When installing the E2E Bridge, BRIDGE  all additional libraries (E2E SQL Libraries, E2E SAP Libraries, and E2E Java Libraries) are being installed as well. After a successful installation, the Bridge BRIDGE is capable to use imported Java classes.
In some cases, you may want the E2E xUML Runtime to use a different Java version to run deployed services. This chapter describes how to change Java adapter preferences to run xUML services using Java classes with a particular Java version.

Preconditions

the E2E Bridge BRIDGE has been successfully installed. When running the Bridge BRIDGE in server mode (as opposed to workstation mode), the E2E Bridge BRIDGE node instance has to be a member of an the E2E Bridge BRIDGE domain (see Installation Modes and Bridge Domain).
The developing environment for xUML services (E2E Builder Scheer PAS BUILDER for MagicDraw) is based on Java. Thus on the BridgeBRIDGE, compiled and deployed xUML services must be run with the same or higher Java version. The Java versions of released Builder BUILDER and Bridge BRIDGE versions are always matching, unless you changed MagicDraw to run with another Java version.

You can check the Java versions of MagicDraw and the E2E Bridge BRIDGE to ensure they are matching.

...

In the navigation, select the Bridge BRIDGE item of the node instance you want to check the Java preferences of (in this example e2ebridge.e2e.ch) and switch to tab Preferences.
Select the Java Adapter from the drop down list.

...

The Java Home directory shows the version of the Java Runtime that is used by the E2E xUML Runtime (see highlighted area above). The Java versions of MagicDraw and the E2E Bridge BRIDGE are matching, as both use the same version 1.6.x.

Java Runtime Environment Versions (32 or 64 bit)

...

In a browser, open the Web-based user interface of the E2E Bridge BRIDGE of the system, on which the Bridge is installed (see  Checking the Installation). Enter a user id and password of a user with administration rights (the pre-defined user admin, for instance).
The welcome page is displayed.

In the Navigation, select the Bridge item of the node instance you want to define the Java preferences for (in this example e2ebridge.e2e.ch) and switch to tab Preferences.
In the drop down list, select the Java Adapter.

...

We strongly recommend to use no Java Runtime older than the one that has been installed with the E2E BridgeBRIDGE. This ensures that deployed xUML services will run properly.
Using Windows, you can copy the path from Windows Explorer (default directory C:\E2E_BRIDGE_PROG\j2re-x.x.x\win32-64).
