I searched through StackOverFlow, spent a lot of time researching on this issue in Google and tried changing the class loading strategy to Parent Last but still I am getting the same error. Here is the list of JARs inside my WEB-INF/lib:

commons-dbcp-1.2.2.jar
commons-logging-1.1.3.jar
commons-pool-1.3.jar

spring-ws-test-2.2.1.RELEASE.jar
spring-xml-2.2.1.RELEASE.jar
xmlschema-core-2.2.1.RELEASE.jar
xmlunit-1.5.jar
Has any body faced this issue? Any help would be greatly appreciated. Should I remove any other JAR? Am I missing something?
I even tried mvn dependency:tree -Dverbose=true -Dincludes=org.apache.ws.xmlschema:xmlschema-core:: but nothing came up :(

IBM WAS has its own implementation of class org.apache.ws.commons.schema.XmlSchemaCollection, located in one of many jars supplied with WAS.
To prevent WAS from loading first class XmlSchemaCollection that doesn't have the necessary method read(), you should use your own xmlschema-core-2.2.1.RELEASE.jar (in version 2.2.1 class XmlSchemaCollection for sure has needed read() method) as IBM WAS shared library.
You can setup shared library and connect it to your web application in WAS administrative console.
It will fix your problem.
