Can you please help to provide information what are the missing jars required to get rod of the exception.
JAX-RPC got deprecated a while ago, and has now been removed (or will be removed) from probably all Jakarta EE servers. I advise to migrate to a more recent API like JAX-WS.
Aside from that, SAAJ is not JAX-RPC (although JAX-RPC builds on top of it, as does JAX-WS). But even adding the JAX-RPC jar files would not work, as that just makes the classes available to the web apps - it still needs to be supported by the server which -as you have found out- it is not.
