Hi all. We are new to using Eclipse 3.0.1 to do Java development.
Is this the right place to ask questions? If not, could someone please
redirect us?
If this is the right place, here's our problem:
1. We made a simple app and it runs fine in IDE.
2. We used File, Export to make a jar.
3. In Windows 2000 (on two different PC's) we double-click on jar and
expect to run, as other jars made with other IDE's or Ant do.
4. We get the message: "Could not find main class."
5. We believe we deeply understand what the jar file should look like
internally. We've inspected the insides, made sure manifest.mf was there,
made sure it had proper formatting of the "Main-Class" line, made sure
package name was included and ".class" was not included, we've compared
this to other jars.
If there is one person out there who has made a jar with v3.0.1 and run it
on windows, we'd sure like to hear from you. We'd like to see your jar
and we'd be happy to post ours.
We are aware of Mozilla bug 47717 and we don't think it solves our
problem, though it sure was a lot of nebulous communication in that bug,
so we can't be sure.
Is there a better place to seek help? At the sun forum we've seen others
with (perhaps) this problem and the respondents gave some pretty mean
answers like "learn to make jar files with your bare teeth, you little
wimp."
This is killing us.
