Remote access invoke issue while executing Windchi...

navyasri · ‎Jul 26, 2023

I am using Windchill PDMLink Release 11.0 and Datecode with CPS N/A

Remote access invoke issue while executing Windchill API's from client machine using Eclipse.

Referred to article CS254321 for RMI.

Here are the errors that I faced

Attached the code I'm using for remote access invoke.

Hi @navyasri

I just guess that Windchill does not load the class what is used.

sun.rmi.transport.proxy.RMISocketInfo

Check if the java class is loaded in Windchill.

There can be a trouble that you use old or newer version of java.

In my case Wch 11.0 uses java 1.8 and it contains rt.jar, where the class is located.

Hi @HelesicPetr

After using the java 1.8 the previous error is gone.

Now getting new error like

wt.util.WTRemoteException: Unable to invoke remote method; nested exception is:
wt.util.WTRemoteException: Unable to locate method server; nested exception is:
wt.util.WTRemoteException: Unable to locate method server; nested exception is:
wt.util.WTRemoteException: Unable to get server; nested exception is:
wt.util.WTRemoteException: Unable to locate server manager; nested exception is:
java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
java.net.SocketException: Connection reset

Any idea on this?

Thanks,

Navya

Hi @navyasri

You need to provide full error where it is thrown. In what method of your code?

Do you use https in your windchill?
