XMLSchemaException exception prevents the starting of SCA applications

Troubleshooting


Problem

When you start a business-level application that uses a Service Component Architecture (SCA) composite, an XMLSchemaException exception might occur and prevent the application from starting.

Symptom

When you start the SCA application, it fails with an exception stack trace that resembles the following text:

org.apache.ws.commons.schema.XmlSchemaException:
Schema name conflict in collection.
Namespace: namespace_URL
    at org.apache.ws.commons.schema.SchemaBuilder.
      handleXmlSchemaElement(SchemaBuilder.java:223)
    at org.apache.ws.commons.schema.SchemaBuilder.
      build(SchemaBuilder.java:202)
    at org.apache.ws.commons.schema.XmlSchemaCollection.
      read(XmlSchemaCollection.java:424)
    at org.apache.ws.commons.schema.XmlSchemaCollection.
      read(XmlSchemaCollection.java:347)
    at org.apache.ws.commons.schema.XmlSchemaCollection.
      read(XmlSchemaCollection.java:379)
