Hi,
I am using the latest version of Java (jdk1.6) and Eclipse. I also
downloaded JavaMail API and the jaf framework. I added both the mail.jar and
activation.jar to the CLASSPATH variable in Windows XP. I am able to run the
javamail sample programs from the command prompt. However, I get an error
message in Eclipse - import of any classes from the javamail api gives me an
error message. What could be the reason? Anyone else run into the same
problem?
Thanks,
Su

I think you might be confusing your compile classpath (that is, the "Java
Build Path") with the execution classpath.
But I'm not sure what you mean by "I get an error message in Eclipse -
import of any classes...". Can you be more specific? Do you mean that you
have a Java project within Eclipse, and you are trying to add an "import
javax.mail.*" line into a Java source file and getting a syntax error?
If that is the case, you probably need to add those .jar files into your
Java Build Path. Look in Project -> Properties -> Java Build Path.

Eclipse does not use the system variable CLASSPATH. Each Project in
Eclipse has its own build classpath. You'll need to import/copy the JARs
into your project and then add them to the project's build path.
This is all explained in detail in the Tutorials. Open the Eclipse Help
Contents and navigate to Java Development User Guide > Getting Started
and you'll see a couple of tutorials that teach you all the basics.
Hope this helps,
Eric

While it works, that is not the most direct or simplest way to go about
it. Most Eclipse users don't know anything about the PDE or creating
plugins.
Far simpler is to import the JARs into the project. If the same set of
JARs are needed by multiple projects, you can either create a User
Library and add that to each project's dependency, or create a small
Java Project that contains the JARs, add them to its build path, and
then make other projects depend on that one.
Hope this helps,
Eric
