need to use xerces parser implementation instead of crimson

[BRIAN MORAS]

Hi

 

I have got the axis happiness page up with all required and optional jar files. 

 

Please let me know how to override crimson to use xerces.

 

 

When I try using one of the examples  from the userguide folder in WEB-INF\axis( a simple one the CalcClient )

I get the following error :

 

Exception in thread "main" AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException

I have been trying in vain to use xerces instead of crimson that comes bundled in jdk1.4.2_04.

 

I have downloaded xerces 2_5_0 and copied the jars to commom/lib of tomcat

 

I have read the article about xmlParsers it tells about choosing xerces ...but How do I do that?

please let me know if anyone has done this.

 

 

any help would be appreciated.

 

Thanks in advance

 

Brian.
