How to consume an ABAP Enterprise Service in JAVA

Dear colleagues:

I'm kind of confused and need your help.

I have already created a Enterpricse Service (for test) in SE80 and configured it through SOAMANAGER.

Question1:

Here is the WSDL URL I got from SOAMANAGER:

http://ldcihri.wdf.sap.corp:50000/sap/bc/srt/wsdl/flv_10002A111AD1/srvc_url/sap/bc/srt/rfc/sap/z_ws2/000/z_ws2/z_binding?sap-client=000

And here is the WSDL URL I got from SE80:

http://ldcihri.wdf.sap.corp:50000/sap/bc/srt/wsdl/flv_10002P111AD1/sdef_url/Z_WS2?sap-client=000：

The XML file I got from the two URL are different, the former is bigger.

Which URL should I use? thanks.

Question2:

I have tested the 2 WSDL URL through Online SOAP Client - WSDLBrowser.com

But both URL failed the test.

I test the same URL in SOAMANAGER-TOOLS-WSDL Analyzer.

Both URL were OK.

Any idea? Is it because the authorization? I need to input user name and password for WSDL Analyzer.

Question3:

I'd like to consume the web service in JAVA.

Is it possible to consume the service in Eclipse IDE?

(I have tried several times by creating Web Service Client using the WSDL but it always say that the WSDL is invalid.

Or I have to consume the Enterprise Service in NetWeaver Develop Studio?
