JCO_ERROR_XML_PARSER

[Former Member]

Hi,

I am using JCO to invoke a function module(DDIF_FIELDINFO_GET). I am building a local Repository to store the metadata. When i do an execute i get the following error

com.sap.mw.jco.JCO$Exception: (130) JCO_ERROR_XML_PARSER: Expecting a tag to begin with '<' instead of 'S', in "><TABNAME>SWISLAPCOM"

what could be the problem? where should i look for to debug this problem. Is there some way I can look into the XML which is actually causing the problem?

Thanks in Advance

Do you do something like this :

functionTemplate = aRepository.getFunctionTemplate( "DDIF_FIELDINFO_GET" );

DDIF_FIELDINFO_GET = new JCO.Function( functionTemplate );

If you have a good debugger you should be able to see all of the metadata being returned after the new JCO.Func...

Look in there for any XML.

Is the function DDIF_FIELDINFO_GET active on R/3 ?

Hi Steve,

Sorry about the delay in responding was sorting out a couple of other issues...

This is what I am doing....

func = repository.getFunctionTemplate("DDIF_FIELDINFO_GET").getFunction();

where repository(not directly from R/3) is a local repository I have built to store the templates.

Then I do a func.execute(); that is when the error occurs. I feel the error is because of the way i have build the function template in the repository.

I feel the error is in the way i have build the metadata for LINES_DESCR (a structure in the export parameter of DDIF_FIELDINFO_GET). Because it is deep structure and I havent tried building metadata for deep structure before this.

If you have tried building metadata for LINES_DESCR or any other deep structure can you show me how to do it.

Thanks

I had this problem myself once, and after long searching I found out that JCO's internal XML parser doesn't like XML comments (Stuff like

<b><!-- This is an XML comment --></b> ).

I had some comments in the XML I used to parametrize my JCO function, and I always got that error. When I finally deleted all the comments, it worked.

HTH,

Hai Andreas,

Where did u find details about the JCO_ERROR_XML_PARSER??

I get a similar error and am not directly working with XML in my code, so need to see why the error occurs. Is there some fix available from SAP for this?

Thanks
