For creating dynamically generated web pages a technology is used known as JavaServerpages(JSP).java is used as scripting language by JSP. The form <%Java code %> is used by the scriptlets, that are used to embed java code within HTML. A part of Java-code embedded in the HTML like JSP code. Everything inside the <% %> tags is called as scriptlet .It accelerate prototyping by it’s explicit use and establish complexity into the implementation.HTML associate with java code by the help of this scriptlets, which leads to problems in code authentication and debugging, that faces difficulties in software maintenance and evolution. As these scriptlets are not reclaimable. so there is a chances of duplication while cuts and paste edits between pages, which gives us error environment.
The implementation of the proposed concept is provided using the JSP (javaserverpages) technology and the performance is computed in different parameters. For extracting the performance of the system memory consumption, server response time and computational overhead is computed. According to the obtained results the proposed models consumes less resource and produce less overhead and produces accurate comparative ranking of different business and scientific domains. In addition of that the proposed ranking methodology provides the clustered domain ranking system by which domain specific ranking becomes more precise and accurate. In order to compute the Webometrics outcomes for the different business and research domains for every organizations a new technique is designed. This technique utilizes the web documents are available on the web search indexing additionally the updates on these web domains are also included to update the ranking scores. The implementation of the proposed methodology needs to find results from the different search engines thus yahoo search, Google web search, Google scholar search, Bing search and duck-duck go search engines outcomes are utilized. The implementation of the proposed Webometrics calculation is performed using JAVA technology and their performance is computed in terms of server response time, memory consumption and computational overhead. The estimated outcomes of their performance are listed using table 1
2) Apache Tomcat Server: The Apache Tomcat® software is an open source implementation of the Java Servlet, JavaServerPages, Java Expression Language and Java WebSocket technologies. The Java Servlet, JavaServerPages, Java Expression Language and Java WebSocket specifications are developed under the Java Community Process. Apache Tomcat, often referred to as Tomcat Server, is an open-source Java Servlet Container developed by the Apache Software Foundation (ASF). Tomcat implements several Java EE specifications including Java Servlet, JavaServerPages (JSP), Java EL, and WebSocket, and provides a "pure Java" HTTP web server environment in which Java code can run.
One of the main reasons why the JavaServerPages technology has evolved into what it is today and it is still evolving is the overwhelming technical need to simplify application design by separating dynamic content from static template display data. Another benefit of utilizing JSP is that it allows to more cleanly separating the roles of web application/HTML designer from a software developer. The JSP technology is blessed with a number of exciting benefits, which are chronicled as follows:
Both the solutions meaningfully slow down set-up time of the call. In the first case the slow performance of XML parsers and the dimension of complex CPL scripts. In the other solution the necessity to make a remote procedure call is implicitly a bottleneck specially with high level of network traffic. In order to avoid these types of bottlenecks a better solution is to create, starting from a profile in CPL format, a pure Java object, whose behavior is equivalent to the specific profile. This Java object will be used by the proxy to directly manage set-up of a call. In this way interpretation of the CPL document is performed once when the profile is updated. The PSM is just a compiler from CPL to Java, and it generates a directly usable Java class: this operation is longer than the single interpretation of a CPL profile, but the advantage is that it is executed once, in a differet process host of the proxy that can continue handling calls, without losing time to wait for the interpretation or compilation of user’s CPL file. Therefore the proxy, as soon as it receives a call, it has only to download the profile object from the repository and to istantiate it. This will be in charge of managing all the incoming calls for this user, and it will be reused for all the following calls that will have the performance of a local call, because the object has already been created and there is no need to download it fro mthe repository, unless a new CPL script is provided by the user. This type of solution guarantees an increased speed of call set-up, compared to traditional solutions: in fact the most time-expensive operations are executed not during the arrival of a new call, but during the definition of the new CPL file.
A Java package called Java Secure Socket Extension (JSSE) is available for producing secure sockets that im- plement the SSL protocol. However, it would have been inefficient to add this socket to every servlet on the server. Another approach, instead, is to use the web server to produce a secure link with the client and to use it to tunnel servlet results. OpenSSL and a special module (ModSSL) for Apache were installed. OpenSSL is an open source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general-purpose cryptography li- brary. The ModSSL module provides strong cryptography for the Apache Server with the help of the OpenSSL toolkit. Once installed and configured a test certificate was created and self signed to test the connection. ModSSL integrates into the Apache server. This allows functionality for the server to use the OpenSSL toolkit to create secured connec- tions. When a visitor contacts the web server, accessing a secured URL (indicated by a URL that begins with ”https:” instead of just ”http:” or by a message from the browser). The server responds, automatically sending the visitor the site’s digital certificate, which authenticates the web server. This certificate also contains the server’s public key. The visitor’s web browser now generates a unique ”session key” to encrypt all communications with the site. The visitor’s browser encrypts the session key itself with the site’s pub- lic key so only the site can read the session key. This is how a secure session is established. It all usually takes only seconds and requires no action by the user. Depending on the browser, the user may see a key icon becoming whole or a padlock closing, indicating that the session is secure. There are a number of security levels that are available for the server from just authenticating itself using certificates, to encrypting all the data being transmitted between the user and the server.
In Computer Engineering, client-server is a software architecture model consisting of two parts, client systems and server systems both communicating over a computer network or on the same computer. A client-server application is a distributed system consisting of both client and server software. The client process always initiates a connection to the server, while the server process always waits for requests from any client. When both the client process and server process are running on the same computer, this is called a single seat setup. The client-server relationship describes the relation between the clients and how it makes a service request from the server and how the server can accept these requests, process them and return the requested information to the client.
pages ―test virtual machine‖ has modified after the copy of its working set has begun. During this phase of the migration, the migrating virtual machine continues to run. Hyper-V iterates the memory copy process several times, with each iteration requiring a smaller number of modified pages to be copied. After the working set is copied to the destination server, the next stage of the live migration begins. Modified pages are transferred. The third stage of a live migration is a memory copy process that duplicates the remaining modified memory pages for ―test virtual machine‖ to the destination server. The source server transfers the CPU and device state of the virtual machine to the destination server. During this stage, the network bandwidth available between the source and destination servers is critical to the speed of the live migration. Using a 1 Gigabit Ethernet or faster is important. The faster the source server transfers the modified pages from the migrating virtual machines working set, the more quickly the live migration is completed. The number of pages transferred in this stage is determined by how actively the virtual machine accesses and modifies the memory pages. The more modified pages there are, the longer it takes to transfer all pages to the destination server. After the modified memory pages are copied completely to the destination server, the destination server has an up-to-date working set for ―test virtual machine.‖ The working set for ―test virtual machine‖ is present on the destination server in the exact state it was in when ―test virtual machine‖ began the migration process. The storage handle is moved from the source server to the destination server. During the fourth stage of a live migration, control of the storage associated with ―test virtual machine,‖ such as any virtual hard disk files or physical storage
Biometrics has proven to provide good authentication. But when using biometrics like a fingerprint, the question that arises is as to where to store the fingerprint. Fingerprint is vulnerable and if the fingerprint template is not stored in a secure place, it is possible that the fingerprint template can be tampered. When considering a basic application providing logical access to PC/Network logon using biometrics, storing the fingerprint at the local computer or server might be enough as the fingerprint represent the digital identity of the person in the local environment and not on the internet. If the scope is PKI based applications (such as VPN, secure email etc) where a smart card is used for credential storage, the fingerprint template should be stored in the smart card. It is important to choose the appropriate level of security for a system. There are different ways to implement biometrics. Two important aspects of biometric systems are
During the first two decades of their existence, computer systems were highly centralized. A computer was usually placed within a large room and the information to be processed had to be taken to it. This had two major flaws, a) the concept of a single large computer doing all the work and b) the idea of users bringing work to the computer instead of bringing the computer to the user. This was followed by ‘stand alone PCs’ where the complete application had to be loaded on to a single machine. Each user had his/her own copy of the software. The major problems were a) sharing information and b) redundancy. These two concepts are now being balanced by a new concept called computer networks. In computer networking a large number of separate but interconnected computers work together. An application that requires two or more computers on the network is called a network application. The client–server model is a standard model for network applications. A server is a process that is waiting to be contacted by a client process so that the server can do something for it. A client is a process that sends a request to the server.
95] are programs typically written in a script language like Telescript [Whi95] or compiled as byte-code segments from a high-level programming language like Java [Fla96]. They are platform independent and may be transported to any host on the Internet and executed re- motely. Remotely executed applets offer an interesting way to implement many distributed applications. Security is the major concern in mobile applets [HCK95], and Java’s security problems in partic- ular have received significant attention. For example, in [DFW96], many security flaws in the Java implementation have been identified. At a recent meeting [SP996], many people have expressed their concerns about Java not having a clear security model and policy. In fact, Java’s security policy is “unspecified” in the language itself. It is the user’s responsibility to implement the public abstract class java.lang. SecurityManager [GY96] to exercise different security models or policies. As we will dis- cuss later, this approach provides insufficient security requirements for many interesting distributed applications like network management.
To distribute live video using the VB150, you create a dedicated web page. The viewers that can be used with the VB150 are “Viewer for Java” (with or without camera control function) and “Viewer for PC”, and detailed parameters can be specified for each of these. You need to determine which of these viewers is supported and create the Web page.
introduce JSP as the technology that can separate them in coding. Whereas Java Servlets are usually coded with both content and presentation, JSP separates the two (Prasad et al, 2001) by using other technologies such as Java Beans to handle the dynamic generation of content. However, while servlets are actual Java code that an ordinary web developer might not be able to develop, JSP works as scripts, similar to PHP, and is supposedly easier to manipulate for the non-Java programmer. Dissimilar to PHP, though, is the ability to embed Java code and Java Beans directly into the script. This presents a problem with Prasad et al.’s (2001) suggestion that JSP is for the non-Java web developer. How does one effectively use JSP without knowing Java? Prasad et al.’s (2001) solution is to have a Java programmer develop those components. For a lone developer unfamiliar with Java but desiring to use the Oracle 8i platform and its web components, it may become a less achievable goal. Prasad et al. (2001) claim that Oracle’s implementation of the JSP specification is the best in the market. Even with the program extensions provided, such as Java Beans for connection, and Oracle’s JSP Markup Language to make development even simpler, there is still a learning curve to overcome for Java, as learned from this project. The ease of JSP may not readily be there for non-Java programmers. Many of Prasad et al.’s examples illustrating the use of a bean or of a built in class still require a certain amount of Java knowledge, albeit not as much as having to develop a servlet. Again, since the primary objective of this paper is to promote the Oracle products, one must be wary of all the claims.
The type of neural network used here is a convolution neural network which is a specifically used algorithm for working with images. The libraries used for the neural networks is Keras with a Theano backend. In order for Theano to be compatible with the dataset images, the images are loaded into a NumPy array which holds all the images. The CNN makes use of the raw data file in order to identify the gestures under consideration. The Neural networks compares the dataset images to the live video feed where each frame of the feed is considered. The gesture which is shown as HSB format is compared to the dataset images in the database. The no of white pixels in both the images are compared. The dataset of the gesture which has the most no of hits is considered as the resultant gesture and hence the prediction is made. The result is reflected on a dynamic bar graph in the java output window which shows the percentage of prediction for each gesture depending on the number of hits it acquired. The connection between the detection module in java and the neural networks module in Python is established using a server socket connection that is socket programming. The connection is localized within the system and is done by handling requests from the server side to the socket side.
3) Improvement in the development of web-based application allowing to modify and add features to existing SaaS. 4) Provision of open-computing platforms for supporting applications written in different programming languages and using any type of database, operating system, and server. The design, development, deploy and maintenance of PaaS- hosted applications are different from the multiple-steps process of traditional hosted application. The purpose of this study is to understand if the two methodologies are comparable and thus the use of PaaS platforms actually facilitates application development throughout its lifecycle, or if the required skills in the use of the tools introduces an additional level of requirements. Traditional development requires an effort to install, configure and then maintain the hosted environment which must accommodate the application, chosen between the different frameworks according the selected programming language. These tasks are time consuming and painful. The development on a PaaS platform requires steps to build the needed environment on the local machine in order to deploy the application. Usually these are operations performed using simple command line tools. For example, Heroku PaaS solution requires that you install a software named Heroku Toolbet that includes a tool for creating and managing Heroku applications (Heroku client), an options for running the application locally (Foreman) and the Git software  that is the free and open source distributed version control system. Then, for supported programming languages (e.g., Ruby, Java, Python, Node.js, Clojure and Scala), it is needed the installation of additional software needed by the language. For example, if the application is written in Java, will be necessary to install the Java runtime kit (JVM) and the Maven 3 software that is a software project management and comprehension tool. Then the application must run on the OpenJDK version that is an open-source implementation of the Java software developer kit (JSE). Anyhow, PaaS solutions have some limitations, since it is not possible to access to features such as the core instances of the processes, storage, networking and routing that could be required by some types of applications such as the legacy ones.

The Citrix SSL Relay Service is a MetaFrame server component that provides encryption, authentication, and forwarding capabilities. This service can be installed on any MetaFrame server; it must be installed on all MetaFrame servers to which clients will attempt SSL connections. Typically, the Citrix SSL Relay Service listens for encrypted SSL traffic on TCP port 443 and decrypts and forwards information to other services on the MetaFrame server, such as the XML service or the ICA listener.
