eclipse - javax.xml.stream.FactoryFinder$ConfigurationError: Provider com.ctc.wstx.stax.WstxInputFactory not found -

i trying develop gwt application calls existing (working) web service. using:

- jax-ws ri 2.1.6 in jdk 6 - jdk 6 - glassfish v3 - eclipse 20110615-0604

i have tested 3 component applications independently , work fine:

1. gwt application - browser invoking gwt server side code. based on gwt sample, http://code.google.com/webtoolkit/gettingstarted.html#create 2. java application uses jax-ws proxy invoke web service. based on jax-ws hello world sample. used wsimport on wsdl generate proxy code. 3. pre-existing web service, have wsdl for.

when merge top 2 pieces of code, create gwt application calls web service within gwt server side code, merged application fails exception below. suspect class conflict between standard gwt dependencies , standard jax-ws dependencies.

i next exception:

earlier getting exception:

[error] javax.servlet.servletcontext log: exception while dispatching incoming rpc phone call com.google.gwt.user.server.rpc.unexpectedexception: service method 'public abstract java.lang.string com.mjg.training.client.greetingservice.greetserver(java.lang.string) throws java.lang.illegalargumentexception' threw unexpected exception: javax.xml.transform.transformerfactoryconfigurationerror: provider org.apache.xalan.processor.transformerfactoryimpl not found @ com.google.gwt.user.server.rpc.rpc.encoderesponseforfailure(rpc.java:385) @ com.google.gwt.user.server.rpc.rpc.invokeandencoderesponse(rpc.java:588)

i solved adding these lines code:

system.setproperty("javax.xml.transform.transformerfactory","com.sun.org.apache.xalan.internal.xsltc.trax.transformerfactoryimpl");

is there other similar work around first exception.

thanks, matt.
