Create a JAR including third party JARS

Question

How can I export my project into a JAR file also including the third party JARs being used from my application (project)?
I think Eclipse does not support this, does it?
The problem is, that when I export my project into a JAR and then manually put the required JARs into the JAR using WinZip I do get such an Exception:
java.lang.NoClassDefFoundError: oracle/ucp/jdbc/PoolDataSourceFactory
In my project I have a class (Runner.java) with a main method which the user can invoke from command line. Furthermore I have a GUI also with a main method which internally invokes Runner.java. How can I start either of themain methods/classes both in the same JAR?
Thank you.

Answer 1

hi, i have a question.
i have an application that uses different third party
jars. For the moment i make my jar like this :
a) i include all my third party jars (it is working)
or is it better to
b) include the jars in the jnlp file
this is best, leaving the third party jars alone.
if b is better should i :
b1) link to them to another jnlp file, like this :
<extension name ....
If you app needs all-permissions, it is best to do it this way, you can, for example, sign your jar, and then ask for all-permissions in the main jnlp file, then not ask for all-permissions in the extension jnlp file. Or you can ask for all-permission in the extension as well, if the third party jars are signed, and need all-permissions to run properly.
or
b2) just put them as resources
if you don't need all-permissions anywhere, this is easiest.
If you do need all-permissions everywhere, you could also do this, but you would need to sign the third party jars with the same certificate chain as you signed your jar.
If the third party jars are allready signed by the third party, or if all-permissions are only needed in some of the jars, the b1 is beter.

Another question :
i sign my jar, but can't access the local file
system. if i use solution a from above, do i have
also to sign the jars that i include in my jar...
You need to add :
<security> <all-permissions/> </security>
to your jnlp file. In that case, all the jars listed as resources in that jnlp file need to be signed, and by the same certificate.
for solution b i think i will have to sign all the
jars... right ?
yes
Thx for your help/Andy
