Developing Applications with WebLogic Server
wldeploy task provides an easy way to deploy directly from the split development directory.
wlcompile provides most of the same arguments as the
weblogic.Deployer directory. To deploy from a split development directory, you simply identify the build directory location as the deployable files, as in:
See wldeploy Ant Task Reference for a complete command reference.
wlpackage Ant task uses the contents of both the source and build directories to create either a deployable archive file (
.EAR file), or an exploded archive directory representing the Enterprise Application (exploded
.EAR directory). Use
wlpackage when you want to deliver your application to another group or individual for evaluation, testing, performance profiling, or production deployment.
For production purposes, it is convenient to deploy Enterprise applications in exploded (unarchived) directory format. This applies also to stand-alone Web applications, EJBs, and connectors packaged as part of an Enterprise application. Using this format allows you to update files directly in the exploded directory rather than having to unarchive, edit, and rearchive the whole application. Using exploded archive directories also has other benefits, as described in Deployment Archive Files Versus Exploded Archive Directories in Deploying Applications to WebLogic Server.
You can also package applications in a single archived file, which is convenient for packaging modules and applications for distribution. Archive files are easier to copy, they use up fewer file handles than an exploded directory, and they can save disk space with file compression.
The Java classloader can search for Java class files (and other file types) in a JAR file the same way that it searches a directory in its classpath. Because the classloader can search a directory or a JAR file, you can deploy J2EE modules on WebLogic Server in either a JAR (archived) file or an exploded (unarchived) directory.
In a production environment, use the wlpackage Ant task to package your split development directory application as a traditional EAR file that can be deployed to WebLogic Server. Continuing with the MedRec example, you would package your application as follows:
