app modules

[Tmmet Johnson]

Hi,
I have the below questions.

1. In my application ear, I have a ejb module (project) and web module(project).
Which module's (ejb / web) will be loaded first by the class loader?
Is it web, since, web classes call the ejbs?.

2. I have a jar file with utility .class files.I have included this jar in the web project's lib folder.But,at runtime,I get "NoClassDefFoundError" when the classes of utility jar is called.
Do I miss any setting?If so, please let me know.
Also, when I include the same utiltiy jar in ear and refer it in web module(Java Jar Dependencies), everything works fine.

Thanks in advance,

The order of classloading depends on the application server and also on classloader setting which you might have defined. Since you not facing any problem when putting the utility jar in the ejb jar , the ejb jar is getting loaded first. Are you using weblogic server ?

This varies with the particular server and
different versions of each server, but
sometimes it helps to provide a
classpath in the manifest in order to
find libraries that are outside the
component war or ejb-jar, but are
in the ear.
