OpenJDK ?

I am working my way through getting jforum 2.3.4 working on Amazon AWS.

However, it seems jforum uses com.sun.image.codec.jpeg.* which is only in the sun/oracle JDK and not in OpenJDK.

This breaks captcha and smilies (maybe other things).

I have tried to get the sun jdk installed and used but all attempts so far have broken other functionality with more severe consequences.

I have seen some discussions where javax.imageio might be used instead the proprietary sun versions. Some examples:

Any thoughts on having jforum use the non-proprietary JDK?

Thanks,
Spencer

The problem is, JForum does not use that package, one of the dependent libraries does (jcaptcha in this case). If it was JForum, it might not be hard to replace with ImageIO (and would be a good thing to do), but as it is one would have to patch that library. A quick look at that source code finds it used in 9 files - I'll take a look at how hard it might be to patch that, but no promises.

What do you mean about the smilies - how are they affected? Those are just static images that are shipped with JForum, and should work on any platform.

This is a JCaptcha 1.0 jar file where I have replaced the com.sun.image.codec.jpeg stuff with javax.imageio.ImageIO. Replace the jar you currently have with this one and see what happens. Please understand that I have done no testing with this, it's just a build with the altered sources.

That has fixed the captcha. Thank you.

The smilies were broken when I tried to solve another problem. Jforum was intercepting my <welcome-file-list> that had index.htm. I renamed the index.jsp to forum.jsp which causes the smiles to to be looked for in http://www.mapbake.com/forum.jsp/images/smilies/... instead of http://www.mapbake.com/images/smilies/...

In SystemGlobals.properties I set:

forum.link = http://www.mapbake.com/forum.jsp
homepage.link = http://www.mapbake.com/

Do you know if I can correct this without causing my main page to be intercepted by jforum?

Thanks again for your help.

I don't think I understand the problem - JForum's servlets and filter are mapped to "*.page" by default. That it would intercept an *.htm file sounds like you may have changed some things from their default...? What's more, JForum doesn't use JSP, so you shouldn't map any JSP pages.

I saw that jforum servlets are mapped to *.page. I may have mis-stated what was happening. When I went to the domain with no page specified it was going to jforum and not the index.htm which I specified in the <welcome-file-list> of web.xml.

There are 3 jsp files provided with jforum (index.jsp, install.jsp, and ping_session.jsp) in web. I changed index.jsp to forum.jsp and it now goes to my index.htm instead of jforum.

I posted about this on another thread (<welcome-file-list> ignored).

I think setting SystemGlobals.properties as:

forum.link = http://www.mapbake.com/
homepage.link = http://www.mapbake.com/

may fix it. It worked locally...

I will do some more testing before deploying live later today.

Thanks for your help.

It was the incorrect setting of forum link.

It is working now.

Thank you again.
