JR upgrade and now stack trace

[dtrobert]

 Hi,

 I just upgraded JasperReports from 2.0.5 to 3.5.2.  When I compile my templates, I get this stack trace

 

2009-07-27 16:09:37,944|ERROR|http-80-Processor22[FetchReportCategoriesAction] There was an error fetching all categories

java.lang.IllegalArgumentException:  When using array of Objects as the value of SCHEMA_SOURCE property , no two Schemas should share the same targetNamespace. 

at org.apache.xerces.impl.xs.XMLSchemaLoader.processJAXPSchemaSource(Unknown Source)

at org.apache.xerces.impl.xs.XMLSchemaLoader.loadSchema(Unknown Source)

at org.apache.xerces.impl.xs.XMLSchemaValidator.findSchemaGrammar(Unknown Source)

 

I have hundreds of templates but even if I remove all but one (any one), the same error is shown.  (No error when I remove them all of course). 

 

Here is this basic template

Code:

Found the problem was me running an older version of xerces. Using the one packaged with jasper reports dist resolved it.

Could you please tell us how you solved the problem? We're facing it right now and have no idea of how to solve it.

To be more specific, I upgrade my xerces.jar file to use the one included in the JasperReports distribution.
