SAP Java Netweaver Performance metrics

[hari0011]

Hi everyone,
We are currently working on monitoring SAP Java NetWeaver (7.5) via JMX and need to access certain MBeans remotely. However, we are encountering the following error while accessing some:

java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: com.sap.pj.jmx.mbeaninfo.MBeanInfoSupport (no security manager: RMI class loader disabled)

Could someone guide us on how to resolve this issue for a SAP Java NetWeaver J2EE instance ,ideally through instance properties or JVM parameters without affecting the existing setup? Any tips, best practices, or examples would be greatly appreciated.
Thank you in advance!
