Issue
I'm trying to create a soap web service client and when I go to File > New > Other > WebServices > WebServiceClient.
I'm getting this error:
IWAB0014E Unexpected exception occurred.

I'm using Eclipse 2019.09 and apache cxf2.x V3.3.5 and GlassFish 5.0.1 and jdk 8. I added apache runtime to Eclipse's preferences. I searched allot and none of existing solutions solved my problem. Thanks in advance.
Solution
I downloaded the latest version of Eclipse and that error disappeared! Eclipse IDE for Enterprise Java Developers.
Version: 2019-12 (4.14.0) I recommend clean install rather than update.
