Hi nk,

This maybe the intialization of Array with minimum number in the webservice.

Can you check the Webservice(Is it created by you)?.

Kind Regards,

Hi NK,

The problem you get is caused by, the recieving end is too small to carry, so it is better to check the webservice and the local dynpro array that recieving the values. Go for increasing the size of array

Hi Nk,

Web Services has that problem b'coz it has return n no of records in XML format. It take more times forming in XML format. Web service has the performance issue.

If your not generating model out web service to retreive data from database go for EJB Lookup call the interface directly.

Hi Ninad,

After long time i am replying for this post.

Sample code for lookup ejb

1. addRecord method is interface in EJB

SampleEJB remote = null;

try {

Context ctx = new InitialContext();

SampleEJBHome home = (SampleEJBHome) ctx.lookup("SampleJNDI");

remote = home.create();

String result = remote.addRecord(aTemp1,aTemp2);

} catch (Exception e) {

System.out.println("Exception:" + e.getLocalizedMessage());

}

Regards

Suresh

Hi ninad,

1. Write one java main program inside put above code look up your ejb and call corresponding interface which u want.

2. run that application you will find exact line which gives error.

3. add jar files and EJB project. Add VM Argument also.

still problem exists mean paste your code

Regards

Suresh
