EJB Simulator Which Simulate the Other EJB and the Developer Can Move Ahead with the Unit Test of His Component and Thus Time Will Be Saved Guru Nanak Dev University Regional Campus, Gurdaspur A Project Report On “Enterprise Java Beans Stub Simulator” For the partial fulfilment for the award of the degree of B.Tech SUBMITTED BY Swajot Singh 74219 Reg. No.: 2006.RG/A.156 UNDER THE GUIDANCE OF Ms. Taqdeer Professor (Dept of CSE) Department Of Computer Science & Engineering 2009-2010 Declaration I hereby declare that the present report has been prepared after the completion of my six months industrial training at Accenture Services Pvt. Ltd., Bangalore and is submitted only at G.N.D.U RCG and not at any other institution for the attainment of any other degree. Swajot Singh 2 | P a g e Acknowledgement Apart from the efforts of me, the success of any project depends largely on the encouragement and guidelines of many others. I take this opportunity to express my gratitude to the people who have been instrumental in the successful completion of this project. I would like to show my greatest appreciation to Mr. Srinivas Kondamudi (Manager). I can’t say thank you enough for his tremendous support and help. I feel motivated and encouraged every time I attend his meeting. Without his encouragement and guidance this project would not have materialized. I would like to thank my Team Leader, Mr. Chandrashekar for the valuable guidance and advice. He inspired me greatly to work in this project. His willingness to motivate me contributed tremendously to this project. I also would like to thank him for showing me some example that related to the topic of the project. The guidance and support received from Mr. Madhu Shanmugam (Senior Programmer) was vital for the success of the project. I am grateful for his constant support and help. I cannot let go this opportunity to thank the most to the project guide assigned to me by the university, Ms. Taqdeer for her belief in this project and for her faith in me and for investing her energies in this project. She has been sole inspiration to hard work and she has been most helpful guide and she has always been so concerned that it has helped me to improve the quality of the project. 3 | P a g e Besides, I would like to take this opportunity to thank the authority of Accenture Services Pvt. Ltd for providing me the opportunity to work in this project and providing with a good environment and facilities to complete this project. Finally, an honorable mention goes to my family and friends for their understanding and support. Without the help of the particular that mentioned above, I would have faced many difficulties while doing this project. 4 | P a g e My Role The project assigned to me was to develop a tool that would simulate the Enterprise Java Beans and this will have an enterprise vide implementation and the other resource working on this project was Mr. Madhu Shanmugam (senior programmer). The project was ably supervised by Mr. Chandrashekar. My working profile on the project comprised of developing a ‘Graphical User Interface’ for the Client which shall provide him the option to browse and upload jar files and provide checkboxes to select home and remote interfaces. Configure the binding of the JNDI names to the Home Interfaces. To find the methods in the Home and Remote interfaces and to pull the required domain jar from the selected Home and Remote Interfaces. Create the Home and Remote Classes by going through the Home Interface chosen by the User. At Last I needed to compile the Home and Remote Classes and then bind the Home to JNDI name. 5 | P a g e Abstract Imagine a scenario where the client (can be an external/internal) needs to access an EJB which has still not been developed yet. Without the EJB the client cannot continue his development/testing. This would result in a decrease in productivity. In such a situation we can deploy a simulator which will simulate the EJB which is not present and will give the output to the calling Client and this would mean that even in the absence of the actual EJB required the client can continue with the process of development and/or testing and this would result in saving in valuable time and has a very practical importance in the enterprise wide working because such issues are encountered very often that we need certain EJBs and they still are not been developed so this tool/project will solve such an issue and therefore client can not only save time but money as well. We need a tool that can simulate the EJB which will help in continuing the development and testing. The simulator would help in carrying out testing process in case of unavailability of an Enterprise JAVA Bean that is being called by another Enterprise JAVA Bean that is to be tested so the stub would provide the test results and thus help in speeding up the testing process. It would automate the process of giving test outputs for the particular Enterprise JAVA Bean while we perform testing. There exists no previous version of this application so this application is being developed from scratch and the tool is aimed to be generic in nature. These are the few key features/functionalities that the aimed tool needs to serve: The project is aimed to be implemented in the areas involving the development of the applications where the different EJBs interact with each other to give an output. The project is aimed to stub an EJB where the client can interact with the EJB which has still not been implemented. It involves developing a tool that would help to simulate this process and component testing can take place. The tool being developed is a generic one so that it can be used/help simulates for various enterprise applications. It can be effectively be used to increase the speed of developing a new application where the client in need for looking up an EJB can use this tool to generate the stub of the actual EJB which has not yet been developed and continue their development and unit/component testing. Hence making the process of coding and testing to an extent parallel to each other. 6 | P a g e Table of Contents Acknowledgement ........................................................................................................................................ 3 My Role ......................................................................................................................................................... 5 Abstract ......................................................................................................................................................... 6 Introduction ................................................................................................................................................ 11 Issues/Risks ............................................................................................................................................. 14 Company Profile .......................................................................................................................................... 15 ACCENTURE SERVICES Pvt.

  • Real-Time Java for Embedded Devices: the Javamen Project*
    REAL-TIME JAVA FOR EMBEDDED DEVICES: THE JAVAMEN PROJECT* A. Borg, N. Audsley, A. Wellings The University of York, UK ABSTRACT: Hardware Java-specific processors have been shown to provide the performance benefits over their software counterparts that make Java a feasible environment for executing even the most computationally expensive systems. In most cases, the core of these processors is a simple stack machine on which stack operations and logic and arithmetic operations are carried out. More complex bytecodes are implemented either in microcode through a sequence of stack and memory operations or in Java and therefore through a set of bytecodes. This paper investigates the Figure 1: Three alternatives for executing Java code (take from (6)) state-of-the-art in Java processors and identifies two areas of improvement for specialising these processors timeliness as a key issue. The language therefore fails to for real-time applications. This is achieved through a allow more advanced temporal requirements of threads combination of the implementation of real-time Java to be expressed and virtual machine implementations components in hardware and by using application- may behave unpredictably in this context. For example, specific characteristics expressed at the Java level to whereas a basic thread priority can be specified, it is not drive a co-design strategy. An implementation of these required to be observed by a virtual machine and there propositions will provide a flexible Ravenscar- is no guarantee that the highest priority thread will compliant virtual machine that provides better preempt lower priority threads. In order to address this performance while still guaranteeing real-time shortcoming, two competing specifications have been requirements.

  • Paper Discusses the Advantages and Disadvantages of Each Approach As Well As Specific Experiences of Using Java in a Commercial Tape Drive Project
    Java and Real Time Storage Applications Gary Mueller 195 Garnet St Broomfield, CO 80020-2203 [email protected] Tel: +1-303-465-4279 Janet Borzuchowski Storage Technology Corporation 2270 South 88th Street M. S. 4272 Louisville CO 80028 [email protected] Tel: +1-303-673-8297 Abstract Storage systems have storage devices which run real time embedded software. Most storage devices use C and occasionally C++ to manage and control the storage device. Software for the storage device must meet the time and resource constraints of the storage device. The prevailing wisdom in the embedded world is that objects and in particular Java only work for simple problems and can not handle REAL problems, are too slow and can not handle time critical processing and are too big and can’t fit in memory constrained systems. Even though Java's roots are in the embedded application area, Java is more widely used in the desktop and enterprise environment. Use of Java in embedded real time environments where performance and size constraints rule is much less common. Java vendors offer a dizzying array of options, products and choices for real time storage applications. Four main themes emerge when using Java in a real time storage application; compiling Java, executing Java with a software Java Virtual Machine (JVM), executing Java with a hardware JVM and replacing a real time operating system (RTOS) with a JVM. The desktop and enterprise environment traditionally run Java using a software JVM that has been ported to a particular platform. The JVM runs as a task or process hosted by the platform operating system.

  • Dalvik Bytecode Acceleration Using Fetch/Decode Hardware Extension
    Journal of Information Processing Vol.23 No.2 118–130 (Mar. 2015) [DOI: 10.2197/ipsjjip.23.118] Regular Paper Dalvik Bytecode Acceleration Using Fetch/Decode Hardware Extension Surachai Thongkaew1,a) Tsuyoshi Isshiki1,b) Dongju Li1,c) Hiroaki Kunieda1,d) Received: May 6, 2014, Accepted: November 10, 2014 Abstract: The Dalvik virtual machine (Dalvik VM) is an essential piece of software that runs applications on the Android operating system. Android application programs are commonly written in the Java language and compiled to Java bytecode. The Java bytecode is converted to Dalvik bytecode (Dalvik Executable file) which is interpreted by the Dalvik VM on typical Android devices. The significant disadvantage of interpretation is a much slower speed of program execution compared to direct machine code execution on the host CPU. However, there are many tech- niques to improve the performance of Dalvik VM. A typical methodology is just-in-time compilation which converts frequently executed sequences of interpreted instruction to host machine code. Other methodologies include dedi- cated bytecode processors and architectural extension on existing processors. In this paper, we propose an alternative methodology, “Fetch & Decode Hardware Extension,” to improve the performance of Dalvik VM. The Fetch & De- code Hardware Extension is a specially designed hardware component to fetch and decode Dalvik bytecode directly, while the core computations within the virtual registers are done by the optimized Dalvik bytecode software handler. The experimental results show the speed improvements on Arithmetic instructions, loop & conditional instructions and method invocation & return instructions, can be achieved up to 2.4x, 2.7x and 1.8x, respectively.
