JCo protocol error

[Former Member]

Hello,

I try to connect with JCo and seem to get connected.

When trying to do a check of the connection in "SM59 RFC Destinations" I get only a "connection closed".

In the RFC Trace I see the following:

>>> RfcDispatch [1] ...
Received RFCHEADER [1]: 01/LIT/IEEE/SPACE-U2/4103
Error ab_RfcSetHeader> invalid compression value  received

   ERROR: ab_RfcGetName [1]
   Invalid protocol version detected
<* RfcDispatch [1] : returns 22:

I tried different versions of JCo 2.0.5, 2.0.10, 2.0.12 and even 2.1.6. It's always the same, and I can't find a way to influence something with compression.

What's wrong here ?

I am encountering the same error and it appears to be related to a communicating between a unicode and non-unicode application. When setting the SM59 connection to Unicode and testing with what I expected to be a Unicode enable Jco Server I encounter the same error you have here. Have you figured out this problem yet?

[Former Member]

Yes, I tried all combinations.

At the Moment Unicode is enabled on both sides.

The Data is transfered with no Problems as far as I can see.

The strange thing is just this error when testing the connection, everything is working fine.

Hi,

Are you trying to Connect to R/3 using JCO or r u trying to connect to Java program from R/3 using JCO..

Let me know please..

Hi,

it is a Java Programm acting as a "registered server program". It gets connected and registered.

The error occurs when testing the connectino in SM59.

The point is it is not a new program. It works perfectly on other customer installations.

The SAP is a Netweaver 04 SR1.

I attach the short RFC trace below, maybe that helps.

Regards

Uwe
