There are two problems here. Looking at the source code, the problem is that you received back a com.ibm.as400.access.IFSReturnCodeRep from your attempt to exchange attributes the AS/400 file server. The problem is that the level of JTOpen that you're dealing with is not prepared to handle a failed attempt to exchange these attributes when that attempt returns an IFSReturnCodeRep object. If you upgrade to the latest JTOpen on the client side, it will decode the IFSReturnCodeRep and put out a message like Unexpected IFSReturnCodeRep, return code xxxx This will allow further diagnosis of what the underlying problem is. If we could see the trace and stack trace from the current version of JTOpen it will help.
