32 bit Java on 64 bit Windows 7 for running JBoss JSP Editor in Eclipse Juno

Question

I installed JBoss Tools on my Eclipse Juno. It worked, then when I click the tab design/view/ whatever it is except the source on my JSP window, It said that JBoss tool for JSP editor cannot run on my 64-bit Eclipse, JRE7, and Windows 7.

I've been browsing all over the place, some forums say you have to change your JRE to 32-bit. After that I installed JRE7 32-bit, restart and I tried to see the Java on Control Panel.

When I clicked Java tab on Control Panel, it said

Couldn't open \\lib\\i386\\jvm.cfg.

I tried to checked on CMD, I typed java -version then it displayed

Unable to load native library: Can't load IA 32-bit.dll on AMD 64-bit platform.

Answer 1

I advise you to uninstall all Java instances, then start again.

Install 64-bit JDK first, set up your normal development tools to use it. Then install the 32-bit JDK but don't install the public JRE . Then configure a separate instance of Eclipse to use the 32-bit JDK. (I'd keep a separate, normal 64-bit Eclipse around, because 32-bit means you are limited to about 1.5Gb of heap for Java)
