Proxy client issue

Question

Hi,
I am trying to build a stand-alone Java client accessing a given Web Service.
I took the jar file in C:\bea\weblogic700b\server\lib\knex.jar for the imported
classes by the proxy. At run-time I got the following error:
C:\Test\wl70>java -classpath %classpath%;. Main
**** ERROR **** Failed to instantiate "dcw"
You are attempting to use this proxy with incompatible versions of required jars.
Please verify tha
t the jars on your classpath are consistent with those jars used by the instance
of Workshop used to
generate this Proxy.
Error: weblogic.knex.parser.JwSyntax; Local class not compatible: stream classdesc
serialVersionUID=

at weblogic.knex.dispatcher.SoapCall.<clinit>(SoapCall.java:41)
at dcw.getRate(dcw.java:73)
at Main.main(Main.java:9)
Which jars I should use instead?
Thanks much

Answer 1

Ian,
The problem is: If you use the class path as you mentioned, some classes could
not be found (see below). On the other hand, if you use the jar C:\bea\weblogic700b\server\lib\knex.jar,
we are back to the original error I posted ealier. What is the solution?
Thanks

Hi, Ian,
Thanks for the answer. But I am not so sure about how Workshop startsthe
server.
Which script should I look into in order to find the workshop-enabledserver class
path?

Hi. Thanks for the question.
I haven't whittled it down yet so I don't know exactly what the "bare
minimum" classpath setting you need to run the proxy, but I know that
if
your client classpath has exactly the same entries as your
Workshop-enabled
server classpath, you can run the proxy without errors.
