javax.comm in JDeveloper

Colleagues,

I'm using a java application to read the data from the instrument via COM port.  I was using Sun JavaOne until my client insisted on to switch to JDeveloper, since they are using it.  Now trhe code doesn't compile, saying

      Error(3,1): cannot access directory javax\comm; verify that directory is reachable from classpath and/or sourcepath

when I do

      import javax.comm.*;

The 2 identical comm.jar files sit here:
      
      C:\j2sdk1.4.2_04\jre\lib\ext
      C:\j2sdk1.4.2_04\lib

The CLASSPATH is
      
      C:\j2sdk1.4.2_04\lib\comm.jar; E:\n\kalaco\comm\app

This arrangement was working fine with JavaOne.  How can I fix the situation in JDeveloper?

Thank you,
Kender

so it appears you need to add the jars to your project using project settings.

Objects,

How do I add a .jar to the project? Could you walk me through?
