744 WebSphere Studio Application Developer Version 5 Programming Guide A red exclamation mark may indicate that there is a problem with the patch. The reason for the failure is found in parenthesis. In our case, the exclamation mark indicates that we are adding new files. If all is well, click Finish to apply the patch. The workspace now contains outgoing changes for each file modified by the patch, as indicated with > signs in the J2EE Navigator view (Figure 22-51). Figure 22-51 Results of the patch As you can see, Test.java, TestBean.java, and TestHome.java files have been added, and ejb-jar.xml and ibm-ejb-jar-bnd.xmi files have been updated by the patch, and are ready to be committed to the CVS repository. Options for applying a patch To get successful matches of a patch file you have the following options in the wizard:  Go back to the first page of the Resource Patcher wizard and select the correct resource to which the patch should be applied.  If a common prefix of the path names stored in the patch file does not match the path names in you current workspace, you can select Ignore leading path name segments (Figure 22-50 on page 743). Note: To apply the full patch successfully you have to eliminate the problems (red exclamation marks) and get checked items everywhere by tweaking the options on this wizard page (see “Options for applying a patch” on page 744). Chapter 22. Using Concurrent Versions System 745  Select the Ignore white space option to make the matching process independent from white space differences between the patch file and files in your workspace.  Adjust the maximum fuzz factor that determines how far from its original line a patch is allowed to match. The default is two. If a patch does not match at the line given in the patch file, the Resource Patcher tries to match the patch fuzz number of lines before or after the position.  Use the Reverse patch option for patch files that already have been applied to your workspace. This option is also useful to undo or redo a patch. Disconnecting a project You can disconnect a project from the repository. Select the ItsoBank5Utility project and Team -> Disconnect . You are prompted to confirm and also if you want to delete CVS control information (Figure 22-52). Figure 22-52 Disconnect confirmation CVS adds special directories named CVS to the project and its folders. These directories can be deleted or kept on disconnect. Reconnect You can reconnect a project to the repository ( Team -> Share Project ). Reconnect is easier if the CVS folders are still in the project. If they were deleted, you are prompted to synchronize your code with the existing repository code. 746 WebSphere Studio Application Developer Version 5 Programming Guide Summary This chapter describes how to set up and configure CVS for working with Application Developer. Through a simple scenario we showed how developers interact with CVS in serial and parallel development. We also showed the compare and merge tools and the resource history. CVS provides a simple but efficient team development environment. You should consider CVS even in a single workstation environment so that you get the benefits of versioning your own code. © Copyright IBM Corp. 2003. All rights reserved. 747 Chapter 23. Using ClearCase In this chapter we demonstrate how to use ClearCase LT with Application Developer. The following topics are covered:  What is Rational ClearCase?  Basic ClearCase terminology  Installing ClearCase LT Server and Client  ClearCase integration with Application Developer  A simple scenario using ClearCase with Application Developer 23 748 WebSphere Studio Application Developer Version 5 Programming Guide What is Rational ClearCase? Rational ClearCase is a software configuration management (SCM) product that helps to automate the tasks required to write, release, and maintain software code. Rational ClearCase offers the essential functions of version control, workspace management, process configurability, and build management. By automating many of the necessary and error-prone tasks associated with software development, Rational ClearCase helps teams of all sizes build high quality software. ClearCase incorporates Unified Change Management (UCM), Rational's best practices process for managing change at the activity level and controlling workflow. UCM can be applied to projects “out-of-the-box”, enabling teams to get up and running quickly. However, it can be replaced with any other process that you already have in place at your site. ClearCase provides support for parallel development. With automatic branching and merge support , it enables multiple developers to design, code, test and enhance software from a common code base. Snapshot views support a disconnected use model for working away from the office. All changes since the last snapshot are automatically updated once you are connected again. Rational offers two version of the ClearCase product:  ClearCase  ClearCase LT ClearCase LT is a light version for support of small teams that do not need the full functionality of the complete ClearCase product (distributed servers, database replication, advanced build management, transparent file access). For the full-sized ClearCase, Rational also provides an add-on MultiSite feature. For more information see: http://www.rational.com/products/clearcase Note: Application Developer 5.0 includes ClearCase LT. Chapter 23. Using ClearCase 749 Basic ClearCase terminology  Activity—A unit of work performed by an individual. In UCM an activity tracks a change set, that is, a list of versions of files created to perform the work (for example, Developer 1 fixing problem report #123). When you work on an activity, all versions you create are associated with that activity.  Component—A set of related directory and file elements. Typically, elements that make up a component are developed, integrated, and released together. In Application Developer, a component contains one or more projects.  Baseline—A version of a project.  Development stream—Each developers’ own working area.  Integration stream—A shared working area for the team, containing the versions of the components that are available to all developers.  Deliver stream—The act of making a developer’s development stream available to the integration stream, publishing a developer’s work.  Rebase—The act of retrieving a project to work on locally, or to synchronize your development stream with what is available in the integration stream.  Check in and check out—A file that is to be edited must be checked out. This lets other developers know that the file is opened by another developer. Once a developer completes any edits on a file, it must be checked back in before making the files available to others.  VOB (versioned object base)—The permanent data repository where ClearCase stores files, directories, and metadata.  View—A selection of resources in a VOB, a window to the VOB data. Installing ClearCase LT Application Developer 5.0 includes both the Rational ClearCase LT Server and Rational ClearCase LT Client products. From the Application Developer product installation dialogs you can start the installation of ClearCase LT. You can also start the ClearCase LT installation from the Rational_ClearCase_LT directory on the Application Developer 5.0 CD. Installing the ClearCase LT Server component also installs the ClearCase LT Client component. We recommend you install the ClearCase LT Server component before installing ClearCase LT Client on any additional machines. Detailed instructions on how to install Rational ClearCase LT are provided in the cc_install.pdf file, which is located on the Application Developer 5.0 CD in: Rational_ClearCase_LT\Rational_ClearCase_LT 750 WebSphere Studio Application Developer Version 5 Programming Guide Installing ClearCase LT Server Application Developer includes a license for the ClearCase LT Server product that enables you to install the product locally on your Application Developer machine to try it out, but not to install it on another machine. To install it on another machine, you must acquire a separate ClearCase LT Server license. Figure 23-1 shows our setup. Figure 23-1 ClearCase LT setup for this chapter Notes:  When installing the ClearCase LT Server, you can be logged on either locally on your Windows machine or logged on to a Windows domain. If installing while logged on locally, you will only be able to connect to the server from your local machine. Other people in your development team will not be able to connect to your machine and use your ClearCase LT Server. The user account used when installing must be a member of the local Administrators group.  To use ClearCase LT in a team environment and let other team members use your ClearCase LT Server, you must be logged on to a Windows domain with a user account having Domain Administrator privileges while installing ClearCase LT Server. The domain must also have a group for the ClearCase users and all members of your development team must be members of this group. This group should also be the Primary Group for these users. You can use the Domain Users group for this. It is highly recommended to use the Windows domain approach. In our example we used this approach.

Using ClearCase 751 To install ClearCase LT Server, perform these steps:  To start the installation, run setup.exe from the Rational_ClearCase_LT directory on the Application Developer 5.0 CD.  Click Next on the first welcome page.  On the Choose Product page, select ClearCase LT Server and click Next.  In the popup window that is displayed, click OK to install the product without licensing configured (the license comes with Application Developer 5.0).  Select Ye s to accept the licensing agreement on the next page and click Next .  On the Select Configuration page, select Typical configuration and verify the install path (we use the default of C:\Program Files\Rational). Click Next .  If the Update Shared Components dialog is displayed, click Next .  Click Next on the Confirmation dialog to start the installation.  When the product is installed, select Restart and then click Finish to reboot your machine.  After the machine has rebooted the installation continues and when done it displays an Error Summary asking you to associate a license with the ClearCase LT Server. You do not have to do this so click Next on the Error Summary page.  On the Installation Complete page, click Finish .  The ClearCase LT Server Wizard is now displayed. The wizard guides you through the process of creating a ClearCase storage directory, a ClearCase VOB and setting up a ClearCase project. On the first page of the wizard click Next .  On the second page, select a directory to store your ClearCase VOB files. Keep the default and click Next .  On the third page, keep the default VOB name sources and deselect the Import projects . Click Next .  On the fourth page, keep the default project name InitialProject and click Next .  On the Summary page, click Next and when the setup is done click OK on the final dialog. When you have installed the ClearCase LT server, review the Rational ClearCase: Upgrades, Patches and Service Releases page on the Rational Web site and make sure that the latest fixes have been applied. The Web site can be found at: http://www.rational.com/support/downloadcenter/upgrades/index.jsp 752 WebSphere Studio Application Developer Version 5 Programming Guide Installing the ClearCase LT client To install ClearCase LT Client perform these steps:  To start the installation, run setup.exe from the Rational_ClearCase_LT directory on the Application Developer 5.0 CD.  Click Next on the first welcome page.  On the Choose Product page, select ClearCase LT Client and click Next.  In the popup window that is displayed, click OK to install the product without licensing configured (the license comes with Application Developer 5.0).  Select Ye s to accept the licensing agreement on the next page and click Next .  On the Select Configuration page, select Typical configuration and verify the install path (we use the default of C:\Program Files\Rational). Click Next .  If the Update Shared Components dialog is displayed, click Next .  Click Next in the Confirmation Dialog.  On the ClearCase LT Server Name page, enter the host name of the machine where ClearCase LT Server is installed. Click Next .  When the product is installed, select Restart and click Finish to reboot your machine.  After the machine has rebooted, the installation continues and displays the Installation Complete page. Click Finish . ClearCase integration with Application Developer Application Developer integrates support for ClearCase, allowing easy access to ClearCase features. Note: Installing the ClearCase LT Server component also installs the ClearCase LT Client component so you do not have to install the client separately on the server machine to access the server. Note: The ClearCase Adapter is a feature during Application Developer installation. It must be installed to make use of ClearCase LT. Chapter 23. Using ClearCase 753 ClearCase help in Application Developer Application Developer provides limited documentation for using ClearCase. To access the help documentation, select Help -> Help Contents to open the new help window. Select Rational ClearCase from the Contents view to open the ClearCase help book (Figure 23-2). Figure 23-2 ClearCase online help ClearCase preferences There are a number of ClearCase preferences that you can modify by selecting Window -> Preferences -> Team -> Rational ClearCase (Figure 23-3). We recommend that you check out files from Rational ClearCase before you edit them. However, if you edit a file that is under ClearCase control but is not checked out, Application Developer can automatically check it out if you select Automatically checkout for the setting: When checked-in files are saved by an internal editor. You can specify if you want to automatically connect to ClearCase when you start Application Developer. Select Automatically connect to ClearCase on startup to enable this option. . on the Application Developer 5. 0 CD in: Rational_ClearCase_LTRational_ClearCase_LT 750 WebSphere Studio Application Developer Version 5 Programming Guide Installing ClearCase LT Server Application.
