Chapter 4. Configuring and starting Process Server

If Business Central and Process Server are installed on separate application server instances (Red Hat JBoss EAP or other), use a separate port for the Process Server location to avoid port conflicts with Business Central. If a separate Process Server port has not already been configured, you can add a port offset and adjust the Process Server port value accordingly in the Process Server properties.

Example:

-Djboss.socket.binding.port-offset=150
-Dorg.kie.server.location=http://localhost:8230/kie-server/services/rest/server

-Djboss.socket.binding.port-offset=150
-Dorg.kie.server.location=http://localhost:8230/kie-server/services/rest/server

If the Business Central port is 8080, as in this example, then the Process Server port, with a defined offset of 150, is 8230.

When you use a class inside a dependency JAR file to access Process Server from Process Server client, you get the ConversionException and ForbiddenClassException in Business Central. To avoid generating these exceptions in Business Central, do one of the following:

System.setProperty("org.kie.server.xstream.enabled.packages", "org.example.**");

System.setProperty("org.kie.server.xstream.enabled.packages", "org.example.**");

<property name="org.kie.server.xstream.enabled.packages" value="org.example.**"/>

<property name="org.kie.server.xstream.enabled.packages" value="org.example.**"/>

-Dorg.kie.server.xstream.enabled.packages=org.example.**

-Dorg.kie.server.xstream.enabled.packages=org.example.**

It is expected that you do not configure the classes that exists in KJAR using these system property. Ensure that only known classes are used in the system property to avoid any vulnerabilities.

The org.example is an example package, you can define any package that you want to use. You can specify multiple packages separated by comma , for example, org.example1.* * , org.example2.* * , org.example3.* *.

You can also add specific classes , for example, org.example1.Mydata1, org.example2.Mydata2.
