THE DEVELOPER PORTAL FOR SOA

Custom task code uses Spring 2.5.6 - clashes with WSO2 1.7.1 Spring version

Hello All, I have built a custom task to do some work. It uses various OSS jar files including Spring 2.5.6. I deployed my jar along with all the depedencies into /webapp/WEB-INF/lib/extensions. Not surprisingly, loading my Spring XML config caused problems which appear to be caused by loading the wrong version of Spring (Error BTW was :org.xml.sax.SAXParseException: Document root element "beans", must match DOCTYPE root "null"). As a general principle, there is no way of deploying libraries which clash with WSO2 versions - i.e. I cannot get a separate class loader for my custom code ? Regards, Serge

BTW , if your are not using ESB spring mediator ... you can remove existing spring jars ...and also if the your spring jar's are new , spring mediator may still work if spring have preserved backward compatibility.
