Setting the compiler compliance level

The Java™ runtime environment (JRE) of both your Rational® SDP workspace and your intended runtime environment must be the same. For example, if you are developing a HATS rich client plug-in to run on an Eclipse environment that is running a 17 Java™ runtime environment (JRE), you must set the compiler compliance level of your workspace to 17. To do this, from the Rational® SDP menu bar, select Window > Preferences > Java > Compiler and set the Compiler compliance level to 17.

If you have other Java™ or plug-in projects in your workspace that require other compliance levels, you can set the compiler compliance level for individual Java™ or plug-in projects. To do this, right-click on the project and select Properties. In the Properties panel select Java Compiler on the left. Then select the Enable project specific settings box and set the Compiler compliance level to the appropriate level.

Note:

The HATS RCP Runtime Extension project, com.ibm.hats.rcp.runtime.extension, must be at the same compiler compliance level as your HATS rich client project. See HATS RCP Runtime Extension project.
