Hi

Did you ever get a solution for this problem?

[Former Member]

No, Later i understood that NWDS 7.1 will create the webservice from WSDL only for the EJB component. So i managed to create the webservice using bottom up approach.

[former_member772487]

Hello Abu Bakar Siddiq,

From your last response i assume that you had a java project and you solved the problem by creating the webservice using bottom up approch.

I have been trying to create a bottom up webservice for a java project but, unfortunately, met with an error "IWAB0014E Unexpected exception occurred". I got this error at the first step of creating of webservice (at the step of selecting 'develop service' and clicking 'next').

I am using 7.31 SP4 of NWDS.

Could you please help me with your suggestioins.

Thanks.
