java.lang.NoClassDefFoundError: com/sun/xml/tree/XmlDocument

Hi

I am running NT 4 + JDK 1.1.7B + SOAP 2.0 rc2 and I am trying to call SOAP
server from the WebLogic 4.51.
Unfortunately one of the EJB-beans is using SUN's jaxp-parser and when I
add xerces.jar before parser.jar
the EJB-Bean which needs parser jar will give me a following error.

Any ideas what I could do for this. I have thought that different parsers
are compatible which each other
but I quess I am wrong. If this is the case it will be really impossible to
maintain environment where you get
components from many different places and versions.

I have tried to use Xerces 1.1.2 and 1.1.3 and Jaxp 1.0 and 1.01
