Depending on your networking and security requirements, you may need to set Java system properties related to proxy servers. Because the connection between the on-premise Integration Server and webMethods Cloud is over HTTPS, you need to set some or all of the following:

Because the proxy property values need to be set for the Java Virtual Machine (JVM) in which Integration Server runs, you update the custom_wrapper.conf to ensure the proxy parameter values are supplied when the JVM launches. Specifically, you add a wrapper.java.additional. n property that specifies the property name and value that you want to pass to Integration Server, where n is a unique sequence number. The property name must be preceded by -D.

For example, the wrapper.java.additional properties in the custom_wrapper.conf file might look similar to the following:

For instructions about passing Java system properties to Integration Server and the JVM used by Integration Server, see the webMethods Integration Server Administrator’s Guide.

To pass system properties to Microservices Runtime, you must update the JAVA_CUSTOM_OPTS property in Integration Server_directory /bin/server.bat(sh). For more information about passing system properties to Microservices Runtime, see Developing Microservices with webMethods Microservices Runtime.
