You can increase the maximum Perm Gen size by launching Eclipse with the VM argument: Note that this issue only appears to happen using an older Sun/Oracle Java Runtime. Generally, you'll find the Source Features in the release-specific repository listed in the installation instructions, WTP_FAQ#How_do_I_install_WTP.3F.Others runtime environments do not seem to have this issue, or may themselves use different methods to control their maximum allowed Perm Gen size. For the Ganymede release, there are instructions provided at this Getting Source link.
Be sure to add both, if more than one is mentioned, and to not mix versions. Launch Eclipse with the -clean option one time to ensure all plug-ins are detected properly and that P2 records a new configuration.A screencast that includes setting up Xdoclet and a JBoss 3.x test server is also available.Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few.Java software for your computer, or the Java Runtime Environment, is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, Java plug-in, Java plugin, Java add-on or Java download.If you do already have Eclipse up and running, Kepler and later versions can install WTP through the Marketplace.
Otherwise, within Eclipse, go to the Help menu, choose Install New Software, and while Working With All Available Sites, choose the features you want from the Web, XML, Java EE and OSGi Enterprise Development category.
For those certain that they only want to install selected parts of WTP, the Eclipse XML Editors and Tools selection is exactly as named, while the Eclipse Web Developer Tools builds on that with HTML, CSS, and Java Script tools, and supports deployable "static" web projects. WTP releases are incorporated into the simultaneous release sites listed below, with the corresponding version-specific WTP update sites used to provide Sources and WTP Adopter documentation, plus the occasional hotfix.
The Eclipse Java Web Developer Tools adds support for JSP files (but not Java Servlets), and complete support for "dynamic" web projects requires the full Eclipse Java EE Developer Tools Feature. If the Simultaneous Release Site and a corresponding WTP site are not already listed on the Available Software Sites Preference Page, you can add them manually.
The WTP SDK (wtp-sdk-*.zip) includes everything produced by the WTP project, including source and both user and programmer documentation.
If you aren't sure which download you need, you should probably get the WTP-SDK.
The default maximum Permanent Generation space set by your JRE may be too small.
