Hi All,

Can any one help me with this problem?

I am using Tomcat 5.0 and eclipse
xmlbeans 1.0.4

My schema file is like this.

I have generated XMLbeans using scomp utility and created a jar.

i am able to parse an XMLString using this

ReportDescDocument.Factory.parse(xmlString);

sample xmlString that i pass to this method is

\n<rpt:reportDesc xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" xmlns:rpt=\"http://broadwing.com/reporting/xml\" id=\"1.1\" label=\"Call Center Planning\" formId=\"usageCallCenterPlanning\" formSource=\"http://eaidev2/xml/schema/UsageForm.xsd\">\n \n <rpt:request reportName=\"CallCenterPlanningReport\">\n \n <rpt:parameters>\n \n <rpt:param name=\"dialedNumberList\" value=\"\" type=\"string\"></rpt:param>\n \n <rpt:param name=\"startDate\" value=\"\" type=\"date\"></rpt:param>\n \n <rpt:param name=\"endDate\" value=\"\" type=\"date\"></rpt:param>\n \n </rpt:parameters>\n \n </rpt:request>\n \n</rpt:reportDesc>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

i get the above xml after XML & XSL transformation.

But when i call repDescDocument.getReportDesc().getFormId() it throws the below mentioned Exception.

Can someone please let me know if this a known isssue?

Here is the stackTrace.
