Running Java applications

Important

Solus does not add Java to the PATH environment variable by default.

There are multiple ways to execute Java applications in Solus:

• Create a .desktop file, then add env JAVA_HOME=/path/to/jdk/bin to Exec.
• Create a script that sets JAVA_HOME before running the application.
• Symlink the java executable from /path/to/jdk/bin to /usr/bin.
• Add /path/to/jdk/bin to your PATH environment variable.
