Hello All,
Thanks for all your replies. I am able to create model and bind it to my component controller.
But when i write the code to call webservice , i am unable to instanciate the model....
I wrote the following code :
testmodel = new Soap(); - (1)
Request_ServiceSoap_insertTicket insert = new Request_ServiceSoap_insertTicket(testmodel); - (2)
insert.setUserId("CCM_RUS");   
wdContext.nodeRequest_ServiceSoap_insertTicket().bind(insert);
private Soap testmodel;
In Above code , line (1) , 'Soap' is the name of my WebService model, which i made by importaing the wsdl file from my local system. And line (2), i amd getting error :
the constructor Request_ServiceSoap_insertTicket(testmodel) is undefined.
If i remove the 'testmodel' and just write Request_ServiceSoap_insertTicket() , the webservice is not called, since model instantiation is necessary for webservice Models. I am stuck
Please help
Thanks
Nishu
