JCO_ERROR_XML_PARSER

[Former Member]

Hello everyone,

first I know that there is another thread regarding JCO_ERROR_XML_PARSER on /message/3284879#3284879 [original link is broken] but as it is in the portal section while my problem isn't a portal issue I decided to post it here in the Java section. Hope that's alright.

Ok let's start. I'm getting a JCO_ERROR_XML_PARSER exception when calling a functional module in R/3. Below you can see the exception I'm getting in Java.

[code]com.sap.mw.jco.JCO$Exception: (130) JCO_ERROR_XML_PARSER: Expecting a tag to begin with '<' instead of '0', in "58320050310"

at [...].sap.function.r3.Z_FUNCTIONS_ZFUBEL01.execute(Z_FUNCTIONS_ZFUBEL01.java:166)[/code]

When I check the relevant position in my trace file I can see the following XML tag structure, but no malformed XML code.

[code]<T_OUTPUT>

<item>

<LINE>0056114100Paid2005KC461416814020050103200502274652059906 460904158320050310.....um41729096/020/AMWEST CONTR41729096020</LINE>

</item>

...[/code]

In R/3 I'm almost getting the same result/output except of one little difference (in Java I get . instead of # right after the position that JCO claims to be faulty).

<code>0056114100Paid2005KC461416814020050103200502274652059906 460904158320050310#####um41729096/020/AMWEST CONTR41729096020</code>

At the moment I'm stuck. Does anyone have a clue what is going wrong?

Any help is appreciated.

Hi Frieder,

Whether your BAPI has nested structure? try to avoid deep structures.

Hi Suresh,

Thank you for your reply but unfortunately we are not using any nested/deep structures in the SAP R/3 function. The export parameter is a table type of type SO_TXTTAB and contains row types of type SQLI (LINE = Char 255).

Therefore I should only get a String with a maximum character number of 255.

Do you or anyone else have any more hints? Thank you guys in advance for your help.

Cheers

Try to validate the xml against an xsd, seems to be an xml parser implementation issue.......

Hi Suresh,

We finally found the reason why the parsing of the XML content failed. There was a packed number (P) within the export parameter string. Obviously JCo can't deal with that although it is an elementary type.

Thank you both for your suggestions.
