I have one JRE in C Program Files x86 Java jre6 and that was the only one at the time I installed Eclipse I have subsequently installed a complete JDK in C home SFTWR jdk1 6 0 21 and changed my JAVA HOME environment variable to that However every time I start a new Eclipse workspace it only picks up the old JRE and I have to manually remove it and add the new one How do I bind my Eclipse install to the new JDK so that every new workspace points to that only I checked eclipse ini but there was no reference there to which JRE to go to UPDATE I went into Prefs- gt Java- gt Installed JREs added the new location marked it as default removed the other and it was effective only for the current workspace However when I opened a new workspace only the old JRE was available So this didn t change the core Eclipse config that is applicable across all at least new workspaces

Finally got it: The way Eclipse picks up the JRE is using the system's PATH.

I did not have C:\home\SFTWR\jdk1.6.0_21\bin in the path at all before and I did have C:\Program Files (x86)\Java\jre6\bin. I had both JRE_HOME and JAVA_HOME set to C:\home\SFTWR\jdk1.6.0_21 but neither of those two mattered. I guess Eclipse did (something to the effect of) where java (or which on UNIX/Linux) to see where Java is in the path and took the JRE to which that java.exe belonged. In my case, despite all the configuration tweaks I had done (including eclipse.ini -vm option as suggested above), it remained stuck to what was in the path.

I removed the old JRE bin from the path, put the new one in, and it works for all workspaces.
