networking issue over WAN.

[jayachandra]

Hi guys,

I too am running into a problem with accessing a webservice over WAN.

I successfully created wsdl2java artifacts, by giving the D parameters for proxyHost, proxyUser and proxyPassword needed and got my artifacts generated.

However when I'm trying to run a TestClient written to use these generated stubs, I'm getting "host parameter is null" exception.

 

These are the series of steps I'm doing.

[[I'm using Axis1.3]]

i) Create WSDL2Java artifacts (giving -Dhttp.proxyHost parameter) by pointing to the WAN wsdl URL (This WSDL is accessible via browser). Artifacts got created.

(ii) Extracted a client-config.wsdd and edited it to use CommonsHTTPSender as http transport

(iii) Used commonshttpclient-3.0-rc2.jar in my classpath and along with it commons-codec-1.3.jar is also put in classpath.

(iv)Wrote a simple TestClient.java to test a stub based invocation of one of the methods of the webservice

(v) compiled the artifacts and the TestClient.java

(vi) Ran java -Dhttp.proxyHost=<my.proxy.com> -Dhttp.proxyPort=80 -Dhttp.proxyUser=<mydomain>\<myuserName> -Dhttp.proxyPassword=<myPasswrod> TestClient

 

And after doing this I have the following error appearing on my screen.

Intially I was using normal HTTPSender, then I was getting the nasty "connection refused"  error. After moving to CommonsHTTPSender and commonshttpclient3.0-rc2 I'm getting this error which is better than earlier one, but something that is not leaving me any clue to resolve it futher. I came close, very close but not till the destination hence am soliciting your help.
