Using a different JDK with JBuilder

Hi All,

I have just got JBuidler 8, and I want to use the latest JDK with it. How /
Can I do this. Also I am building a project using java media api and java 3d
api, how can I get JBuilder to recognise them?

You cant. JBuilder uses its own embedded compiler (which is never good) so
you can not make it use a different JDK.

Netbeans or Gel will allow you to do this (and they are free). Eclipse is
free and quite nice also but unfortunately also uses its own compiler so it
can not be upgraded with a newer JDK.

Is it not just changing the path in preferences? You can chang the JDK
path. Jbuilder has a JDK which downloads with the tool, accounts for 90% of
the size of the download. You can set the JDK path to say
c:\apps\JDK1.4.xxx in the preferences, of the newer JDK that you download
from SUN.

Complete and utter BS.
JBuilder has supported JDK switching since version 4 (or maybe earlier).
Look in the IDE settings (I think, might differ between versions).
To add an external library, check "required libraries" under project
properties.
Netbeans or Gel will allow you to do this (and they are free). Eclipse is
free and quite nice also but unfortunately also uses its own compiler so it can not be upgraded with a newer JDK.

Another BS. Eclipse doesn't even come with a JDK, so HAS to use an external
one.
check window->preferences->Java->installed JREs.

Selecting a different JDK will only use diferent JARs during compilation

and a different JRE during runtime. JBuilder does not allow you to completely
replace JDK functionality (javac). The new assert keyword which was
introduced in 1.4 could not be used in the JBuilder version that was current at the time (don't remember exactly, think it was version 5). Apart from
that the compiler at that time could not read JARs created with the 1.4
javac since the class-file version had been upgraded.
JDK 1.5 will introduce lots of new language constructs. Upgrading the JDK
will be of little use to JBuilder users. They have to wait for the new
release from Borland.

Bottom line JBuilder does not allow a complete upgrade to the newest JDK in general. In the future, if you decide to post a message in such strong
wordings be sure you have all the facts right, otherwise you will look
stupid again.

BTW: Eclipse has an internal Java compiler. For compiling it strictly does
not need a JDK, it needs a JRE though for access to the standard libraries
and for launching applications. The same issues as with JBuilder arise when
newer Java versions are incompatible with the internal compiler.

c:\apps\JDK1.4.xxx in the preferences, of the newer JDK that you download

That's pretty muchwhat I've done so far.
