ECLIPSE IDE

Thanks in advance to responding.
I have been developing with JBuilder 5.0 and using ANT to build my projects. I want to start using Eclipse. I installed it and try to run my build.xml file for ANT and I get the following error:
"Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK"
Not sure what I have set up wrong. I have tried so many things to try and compile my project and to run it from ANT, but nothing seems to work. I think it's an internal classpath setting with eclipse.
Thanks,
jorge

Moving to IDEs and other tools forum...

eclipse's ANT runtime does include tools.jar.
I also have my JAVA_HOME set to C:\jdk1.3
All my environment variable do work when working with JBuilder and ANT to build my apps. I think it's just a small little thing I have to do.
Please advise and thank you in advance.

You need to add 'tools.jar' inside Eclipse: 'Window->Preferences->Ant->Runtime' in the 'Runtime classpath' should the ref. to 'tools.jar' be.

Well, where can I get the history of Eclipse? In short what I know is that Eclipse was developed by IBM and then later open sourced. A little lights on its strngth (is it plugin development?) and weaknesses are most welcome.
I am also looking for a plugin (otherwise to develop) for Eclipse that will connect to Sun One Studio/Application Server, say for checkin-checkout.

short history don't know.
the info is spread over a few pages.
Those I found most usefull:
the wiki was quite usefull: http://eclipsewiki.swiki.net/1
and
this site:

here's overview over existing plug-ins:

Manning is offering a brand new ebook, which I'll buy soon:
http://www.manning.com/gallardo/index.html
