[jboss-user] [Installation, Configuration & Deployment] - java.lang.NoSuchMethodError: org.apache.xerces.impl.xs.XMLSc

I am currently using Jboss 4.01 sp1 and I am trying to load a schema and validate it using xerces. However, the app server is throwing the following exception. java.lang.NoSuchMethodError: org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar([Lorg/apache/xerces/xni/parser/ XMLInputSource;)V at org.apache.xerces.jaxp.validation.XMLSchemaFactory.newSchema(Unknown Source) at javax.xml.validation.SchemaFactory.newSchema(Unknown Source) at javax.xml.validation.SchemaFactory.newSchema(Unknown Source) at com.nielsenmedia.services.util.XMLValidator.(Unknown Source) I had posted this in another forum, and the suggestion was to use the xerces from 4.0.3. However, I am a little confused. Are you saying to copy the xerces from the endorsed directory of 4.0.3 to 4.0.1sp1? Or are you saying let our code use the xerces from 4.0.3?
