Dear Wiki user, You have subscribed to a wiki page or wiki category on "Fedora Project Wiki" for change notification. The following page has been changed by KarstenWade: http://fedoraproject.org/wiki/Docs/Beats/Java?action=diff&rev2=74&rev1=73 The comment on the change is: updating, wish we had more information about the gcjwebplugin ------------------------------------------------------------------------------ {{{ which java && java -version && which javac && javac -version }}} - = Handling Java and Java-like Packages = + === Handling Java and Java-like Packages === In addition to the `java-gcj-compat` free software stack, Fedora lets you install multiple Java implementations and switch between them using the {{{alternatives}}} command line tool. However, every Java system you install must be packaged using the JPackage Project packaging guidelines to take advantage of {{{alternatives}}}. Once these packages are installed properly, the `root` user may switch between {{{java}}} and {{{javac}}} implementations using the {{{alternatives}}} command: @@ -24, +24 @@ alternatives --config javac }}} - = Handling Java Applets = + === Handling Java Applets === - This release of Fedora includes a preview release of `gcjwebplugin`, a Firefox plugin for Java applets. `gcjwebplugin` is not enabled by default because although the security implementation in `GNU Classpath` is being actively developed, it is not mature enough to run untrusted applets safely. That said, the AWT and Swing implementations in `GNU Classpath` are now sufficiently mature that they can run many applets deployed on the web. Adventurous users who want to try `gcjwebplugin` can read `/usr/share/doc/libgcj-4.1.1/README.libgcjwebplugin.so`, as installed by the `libgcj` rpm. The README explains how to enable the plugin and the risks associated with doing so. + This release of Fedora includes a preview release of `gcjwebplugin`, a Firefox plugin for Java applets. `gcjwebplugin` is not enabled by default because although the security implementation in GNU Classpath is being actively developed, it is not mature enough to run untrusted applets safely.

These packages are modified in Fedora to remove proprietary software dependencies and to make use of GCJ's ahead-of-time compilation feature. Use the Fedora repositories to update these packages, or use the JPackage repository for packages not provided by Fedora. Refer to the JPackage website at http://jpackage.org for more information on the project and the software it provides.

With no additional properties defined (the `mvn` command), `maven2` works exactly like upstream Maven. Users may define additional properties to facilitate off-line builds, or call `mvn-jpp`, a wrapper which defines the most commonly used properties for off-line building. The properties and their usage details are described in the `/usr/share/doc/maven2-2.0.4/maven2-jpp-readme.html` file, which comes from the `maven2-manual` package. + The `maven2` package in Fedora is modified to work in a fully off-line mode.
