Error building my first EJB

Question

I am trying to build my first EJB. However, everytime I giev the "ant build" command, I get an erro saying "Validation Problems Were Found". This is the only error i get and Not any syntax errors. Does this have something to do with my remote, local and Home interfaces, the Bean Class or Client, OR is it my build. xml file that has some error in it.

Answer 1

Looks like your ejb-jar.xml is not correct (check the element
<enterprise-beans>). You may post this file so that I can take a look at it.

Thanks for replying. Here is the build.xml file and the error output that
I get when I execute the ant command. My BEAN here is called
<b>SecuirtyEJB.java</b> and all the files including this BEAN are in a
foler named SecuritySystem. Now, here is the build.xml file:

This is the part of the output whee the error message appears and I think
this is the one you want. Hope you can figure out what the problem is here
coz as I said, this is my first EJB program. Thanks
