JCO Error JCO_ERROR_XML_PARSER

[Former Member]

Hi All!

I am making a call to an adaptive RFC module on our SAP 4.7 System.

But i fail in executing the call.

this is the error:

Expecting a tag to begin with '<' instead of '0', in "00000000 ", error key: JCO_ERROR_XML_PARSER

I tried searching the forum for results, an saw that this error is because of an error in the metadata XML file.

But, this is Webdynpro, and as i am convinced, you are not to change anything in any XML files,

i tried making the call from to different projects, and the error is the same in both.

Anyone has any ideas ?

Help is much apreciated

Hi Ronni

Did you make an changes to back end RFC after importing the model? If so try reimporting it. Restart the J2EE server also.

Hi Again!

My problem was solved

by chaning the RFC which i called.

i found out that the reason

was beacuse of an deep structurue.

when this was changed, there was no problems.

Hello,

I already reimported (no deltas) and restarted the J2EE engine, bur Error is still the same. It has only one input parameter and a struture as an export parameter, so nothing special in this.

Hello,

I think this is a bug in JCo & adaptive RFC here. I will asked for a redesign of the BAPI structure to get a flat structure and try that.

After searching documentation for any hints about this I can't see anything, but obviously its not working. I will open a new thread with the question, whether nested structures are allowed.

With flat structures it works...

Hi Frank,

Deep structures in RFC's are not supported by webdynpro.

Hi,

I have the same problem using adaptive RFC against a 4.6C R/3 System.

Model was imported again, Server was restarted. No XML is written by me...

Anyone has a solution?
