The description information for JNLP module is not correct.

Now the jnlp plug-in description information is "Support for general Java projects,usually J2SE.A J2SE project can compile a Java source root,build a JAR from it,run JUnit-based tests,create Javadoc,and run or debug an application with a main class.No direct support for J2EE or special packaging technologies."
This information can not give the brief function description for this plug-in.
