| Working with JREs |
| </h1> |
| <p> |
| You can install as many different Java Runtime Environments (JREs) as you like. A JRE definition consists of: |
| </p> |
| <ul> |
| <li> |
| The type of the JRE (e.g. Standard VM or Standard 1.x.x VM) |
| </li> |
| <li> |
| A name |
| </li> |
| <li> |
| The location where the JRE is installed |
| </li> |
| <li> |
| The location (URL) of the Javadoc |
| </li> |
| <li> |
| The system libraries containing the Java system classes (like java.lang.Object). Optionally, the system libraries can be associated with the source file containing the |
| source for the classes in the JRE's CLASS files |
| </li> |
| </ul> |
| <p> |
| You can switch the default JRE for the workbench. The default JRE is the JRE to which the pre-defined classpath variables JRE_LIB, JRE_SRC and JRE_SRCROOT are bound. |
