I’m using the Window Builder from Instantiations and that plug-in’s Design view wants to load my classes with their default constructor. But the eclipse JDK inside MyEclipse is JRE 1.5 and my classes are compiled with JRE 1.6. I *think* that’s why the Window Builder can’t load my classes – I’m not sure. Is there some way to make MyEclipse use my 1.6 JRE? Other ideas?

Thanks!

You can go to Windows > Pref > Java > Installed JRE and add JRE 1.6. You can now make this the default JRE by checking it.

I already have 1.6 as an installed JRE and checked. My workspace compiles with 1.6. But the problem is that MyEclipse, which is itself a Java application, runs under the 1.5 JRE. This means (I think) that the Window Builder plug-in won’t successfully load my classes which were compiled with a 1.6 JDK.

Under Window->Prefs->Java->JRE->Execution Environments I have my 1.6 JRE checked for the J2SE-1.5 environment, which also shows My Eclipse 5.1.1 as a choice, which is not checked. Would that be the correct way to make MyEclipse run under that JRE?

When I start MyEclipse and build my workspace I get the following log entry:
!ENTRY com.instantiations.tools 1 0 2008-05-05 07:25:14.359
!MESSAGE com.instantiations.tools stop
!SESSION 2008-05-05 07:28:49.156 ———————————————–
eclipse.buildId=M20070921-1145
java.version=1.5.0_11
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments: -os win32 -ws win32 -arch x86

Doesn’t this mean that MyEclipse is running under the 1.5 JRE and not the 1.6 JRE I’ve selected?

You need to make this change in your eclipse.ini file. Point the -vm argument to 1.6. Let me know if you cant get this to work.

[Walter Stovall]

There is no vm argument. Where does it belong? What should it say?

-showsplash
com.genuitec.myeclipse.product
–launcher.XXMaxPermSize
256m
-vmargs
-Xms128m
-Xmx512m
-Duser.language=en
-XX:PermSize=128M
-XX:MaxPermSize=256M

1. Add this line to the eclipse.ini file:-
-vm C:\jdk1.6.0_04\bin\javaw.exe

Make sure you are pointing at the JDK’s executables, like C:\jdk1.6.0_04\bin\javaw.exe

2. If you used our installer, it already specifies a -VM argument. Edit the shortcut that is used to start MyEclipse, edit it to point at a JDK on your machine
