It looks to me like your gopa.taglibrary.IncludeTag is calling the weblogic RequestDispatcher instead of the SlingRequestDispatcher, which is attempting to cast the existing Sling JspWriter to a weblogic ByteWriter.
My assumption is that the problem stems from the fact that your tag is calling request.getRequestDispatcher() and instead of getting an instance of org.apache.sling.engine.impl.request.SlingRequestDispatcher, it's getting an instance of weblogic.servlet.internal.RequestDispatcherImpl, which probably works off of the assumption that WebLogic initialized the request in the first place and that all of the JSP objects are WebLogic implementations. I have no idea how you would go about fixing that, unfortunately.
