Hi,

I want to use EMF project in the java project....

I had made the jar of the EMF project and added in the java build path of
my ordinary java project....

I am getting the API's but i am not able to access the methods inside
these classes...

Can you plz tell me regarding this...

You shouldn't need to make a jar. Adding the EMF project to the Java
Build Path via the Projects tab should be sufficient.
Personally I never use just an ordinary project since a plugin project
is much easier to manage and ultimately can be used to build a jar that
functions stand alone.

You'd need to add the jar for all the plugins that your model project
depends on, e.g., org.eclipse.emf.common and org.eclipse.emf.ecore.
(It's much easier to let the PDE manage your classpath via dependencies.)

Zakir,

It's definitely a classpath issue, so my best advice is to use plugins
because they manage this much more easily. Ignoring that advice puts
you in the position of needing to set up the build classpath correctly
by hand. If you look at a plugin's dependencies, you can see exactly
which jars it depends as in this example:

So for the library example, you'd need to put the jars for ecore, common
and xmi on the classpath. (EMF does not have a "hard" dependency on
OSGi/Eclipse so you should not need those on the classpath unless you
use those things directly.)
