Hello Ian/Everyone,
Yes,
I have carried out a lot more testing and found that this seems to work
on the first main class or any class that is run with appclient. Any other class
that I call from the main class, results as NullPointer when I try to insert. E.g:
If I try insert data of the same bean from the main class, I get the following:
C:\jee\STOCKINFOR2>appclient -client STOCKINFOR2-app-client.jarsuccessfully recorded new Department details
However, if I call the class from the main class, then I get the following:
C:\jee\STOCKINFOR2>appclient -client STOCKINFOR2-app-client.jarCaught an Exception: can not insert new Department detailsjava.lang.NullPointerException at stockinfor2.NewDepartclient.saveNewDeptdetails(NewDepartclient.java:122) at stockinfor2.NewDepartclient.newdepatbutActionPerformed(NewDepartclient.java:113)
So I guess, I have to use just one JFrame client and use containers such as panels and so forth, to separate this.
Or I have to use lookups - Context.
This' now the limitation with server side JEE combined with Client side programming.
Thanks for your help.
