Hi Sachin,

If you goto transaction ST22 and if it shows the WD-Context error then this must be related to context binding. Check all the nodes and attribute, whether they are binded properly or not. Also check for the code and cardinality of the node. Check in BIND_TABLE method. There must be something missing in the codin.

You can also set a breakpoint in that particular method and see if data is getting populated or not.

Hope this will solve your problem as it helped me for the same error!

Cheers,

Darshna.

Hi Sachin,

The problem seems to be with the BIND_TABLE code.You need to check the cardinality of the node to which you are binding the values.

If you are using BIND_TABLE to a node, then the cardinality of the node should be 0-n or 1-n else it will through error during the binding.

Thanks

Hi Sachin,

First of all Welcome!!!

Web Service URL is not working.Try with other URL.If you dont have any, you can Create your own Web Service. It is very Simple.

Just follow the below steps.

1)Create a Simple Java Project, with one method.. ex:- sayHello(String name){return "Hi.."+name;}

2)Go to WebService Perspective, Go to your Project - Class -> Right Click New -> Web Service -> Give Service name and select methods -> Finish.

3)Right Click on the Project -> Build Ear.

Deploy this .ear file.

Your Service is ready. It has been deployed on the Server.

Create WebService Model from Web Dynpro. For this you can go thru with this link.
