sample example error

[V....@iflexsolutions.com]

Hi,

 

 I'm a beginner for Axis. I tried to deploy the userguide sample. The
service is getting deployed. When I use the EchoBlockingClient 

To call the web service it  gives the following error.

 

Note: I have downloaded the Axis2 1.0 standard distribution and using
inbuilt http-server. Is there any bug with this version?

Please do help me on this error so that I can proceed. I'm stuck up for
past few days
