Ok, folks, I know this is something really simple that I'm missing. I tried Sun's beans tutorial with SimpleBean.java. Followed the directions to the "T". It won't load the JAR file into the Toolbox. It complains about not finding the class file, when it is there. What am I missing or haven't found on the web????? Thanks in advance.

Have you put your jar file in the beans/jars directory?

Class file?  Are you trying to load a jar file or a class file?  The class should be in a jar.

When exactly does it complain about not find the bean?

If you are using 1.4 you may need to include the bean in a package (and as a general point this is recomended).

No, I did not put the jar file in the beans/jar directory. Didn't think I had to do that if I was specifying the location through the Toolbox's "File--->Loadjar" menu option, where it prompts you through a browser for the file location. Jimmack, I am loading a jar file correctly that has a class file and a manifest file in it, but it complains about not finding the class file nonetheless. As for objects comment, I may have to look into that as well, as I am running J2SDK 1.4.2.

OK.  I downloaded and the Beanbox onto my Linux (MDK 9.1) system using J2SDK 1.4.2.

Following the tutorial you mentioned for the SimpleBean produced what was expected.  The only problem I can across was with the button.jar bean.  This was an issue with Introspection (a known problem with 1.4 and beans).

The make file provided in the tutorial creates the jar file and places it in the beans/jar directory.  If you haven't got the jar file in that directory, then you've missed a step somewhere.

I stopped the Beanbox and moved the jar file to another directory (for this test, I put it in the demo directory).  Restarting the Beanbox shows that the SimpleBean is missing, but File|Load jar lets me load it OK from that directory.

It sounds like there may be a problem with the jar file that you have.  Do the following:

> jar tvf SimpleBean.jar

You should see the following (or very similar):

   129 Fri Nov 14 09:54:42 GMT 2003 META-INF/MANIFEST.MF

Folks, nevermind. It was my ineptitude that led to this stupid question. I didn't have a carriage-return in the manifest file as I needed. Thanks for your help anyway.
