JAX-WS Client for 1.4.2

I have a JAX- web service generated using JDK 6. I need to generate a client for it which could run on 1.4.2 environment. Is this possible?
I keep getting "UnsupportedClassVersionError" when I try to run wsimport on the client as shown below:

$ $JAXWS_HOME/bin/wsimport.sh -verbose -B-XautoNameResolution -s . http://127.0.0.1:8080/ReqQuery/query?wsdl
java.lang.UnsupportedClassVersionError: com/sun/tools/ws/WsImport (Unsupported major.minor version 49.0)

Is there anything I need to take care of?

JAX-WS requires Java 5. You need to create the client code some other way. Or upgrade to Java 6; Java 1.4 had been obsolete for years.

Thanks, I thought so but wanted to make sure. Unfortunately the client is for another company's
system having Java 1.4.2 , which I dont have a control on. Can you give some ideas on other ways to generate only the client, if I have the webservice
generated using JAX-WS and Java 6?

The download of the SAAJ API for Java 1.4 would be one option if you feel like writing the code yourself.

Or use Axis or Axis2 for creating the code; older versions-if not the current one- should be compatible with Java 1.4.
