The import cannot be resolved [message #498920]

Hi there,
I develope a jsp using eclipse, and try to call a jar file that I made.
The problem is that when I import the jar into the jsp page, I get an error says:
'The import myClass cannot be resolved'.
I included the jar in the Libraries in the build path. The class I'm trying to use in the jar is public.
I also read that running a 'clean' action (project -> clean) can solve it, and I did it. It didn't solve
my problem.
I still get The import cannot be resolved error.
I'll be glad to here any idea, I didn't find a solution yet Sad

Thanks.

Another thing:

Well, I even put my jar inside the lib in the web project, but it is still not working:
Actually, the jar contains some classes that some of them are recognizad in the "import",
but the class that I built and want to use is not recognized.
I don't know why, driving me crazy !
The both classes are public.
Thanks for any help

What is the fully-qualified name of the class? Did you define the class in a package, or are you using the "default" package? You'll generally have issues if you try to use the "default" package with web applications, although I can't be certain.

That means that class was available at compile time, but not at deployment time. That class needs to be deployed as "WEB-INF/classes/Hasp/hasp_demo.class" or WEB-INF/lib/<jar file containing Hasp/hasp_demo.class>". Is "hasp_demo.java" a source file in your project, or is the "Hasp" package something provided in a jar file that you're using?

It might be useful to do a "File"->"Export"->"WAR file", selecting your project. You can then inspect the resulting WAR file to see if or where that class was deployed to.
