Eclipse is running in a JRE, but a JDK is required错误的解决
在eclipse目录下eclipse.ini,添加如下两行，注意这行要加在-vmargs之前，
-vm
C:\Program Files\Java\jdk1.6.0_25\bin\javaw.exe
----------------------------
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
