bad class file error

[AC]

I keep getting an error when I try to import a jar file into a JSP
using myEclipse:

<%@ page import = "java.util.*,
...
com.directory.class_A,
com.directory.class_B"
%>

The .class files for these classes are in a jar file that is in the
Java build path.

The jar file looks like this:

jar -tf myJar.jar

META-INF/
META-INF/MANIFEST.MF
com/directory/class_A.class
com/directory/class_B.class

The error says:
cannot access com.directory.class_A: bad class file:
/directory/myJar.jar(com/directory/class_A.class). NOTE: No JSP line
number was avaliable so line 1 was used for the marker.

If I switch the order of class_A and class_B, I get the same error for
class_B.

I can't figure out why these classes aren't found. Anybody have an
idea?

Thanks in advance.

Hi,

What JDK and JRE versions are you using?

Have you confirmed that they are compatible?

"I forced Eclipse to use the JDK in the installation directory through
the -vm startup parameter, and the error does not appear anymore."

How do you do this? I've been looking around at the preferences and
through the help manual, but I have not solved this yet.

Thanks for your help.

In other words, what is the JDK in the installation directory? I don't
see any JDK there.
