Unfortunately, we have not tested against the IBM JDK so far. It seems that there maybe some incompatibility.

Maybe you could modify the log.properties in the application directory and send the debug log to uajava-support@prosysopc.com for examination.

You can enable logging on file by adding ‘file’ to the rootLogger:

log4j.rootLogger=INFO,console,file

This turned out to be a problem with byte endianness. Solved by configuring/updating to the latest IBM JDK (if I got it right).

Hello,

Are you receiving the “ServiceResult=Bad_CommunicationError (0x80050000) “A low level communication error occurred.”” error?

Could you tell us more about the situation when the error happens? For example, please tell us what client and server applications you are using. This information helps us to understand the situation.

If you are using IBM Java (as in the case above), please make sure you are using the latest version.

Otherwise, it may be an interoperability issue with the open source server library. If you can post a client side log in DEBUG level it will help to investigate this. Also, you need to investigate this on the server side.
