Natural RPC Java access always throws ArrayIndexOutOfBound

, ,
1
  • Natural 4.1.3 on VSE
  • Broker EntireX 7.1.1.70 on Windows XP Prof
  • Java Client with EntireX Stub 7.1.1.70 on Windows XP Prof

Natural RPC Server (VSE) registers at Broker on windows. When accessing natural rpc server from java stub we get always the exception ArrayIndexOutOfBoundException, independently from the used IDL.

By the way if we use a broker on linux the problem keeps the same.

Looks like you have a rotten Natural installation on VSE.
Natural returns a NAT 6978 plus some garbage which the Java RPC runtime cannot handle.

[i]NAT6978: Version error on :1:, reason :2: :3:.

Expl. Reason: 1: Version of Natural nucleus and version of SYSRPC do not
agree. After the reason, the current version and the
required version are indicated in the message.
2: Server does not support this version.

Actn. Use the correct version(s).[/i]

Problem solved !

Natural error 6978 was caused by the fact that UID in RPC call was longer than 16 Bytes. Because no userid was set in java client the UID was set to RPC/DAEKSV4/CALLNAT (>16 Bytes) by default - this seems to be a problem in natural vse. after setting a shorter userid in the java client by using methods RPCService.setRPCUserId() and RPCService.setRPCPassword() the problem disappeared.

Thanks for the good support.

Good to hear that the issue is solved !

But one thing puzzles me a bit. You say that the Java app does not set a userid and a default one was used. However the EntireX Java RPC runtime does allow an empty userid. So I suspect that somewhere in your application you will find
new Broker(“ETB001:10050”, “RPC/DAEKSV4/CALLNAT”)
the second parameter being the userid.

7

Additional hint for Natural Error 6978 and ArrayIndexOutOfBound:

We got the “ArrayIndexOutOfBound” error (reason again Natural Error 6978) again although we set UID to a short value (like “sag”)
=> solution this time: we had to set name of natural library via method setLibraryName() in java rpc stub.

Regards,
Dirk
