To run the JBuilder Integration Configuration Tool, your PATH environment variable must point to the bin directory of a JDK that can execute .jar files. JBuilder includes a JDK with .jar support and adds it to your PATH variable at install. However, if you have an older JDK version in your PATH, the configuration tool may use this version instead.
If you have problems running the install tool, check that the JDK included with JBuilder is the only JDK in your PATH variable. If you are unable to set your PATH to use this JDK, you must manually set up the integration by running the addin directly.
