I\'ve been using Eclipse for some time already, and I didn\'t have any problems with it. However, when I tried to generate some javadoc, I found that I didn\'t have the SDK
I had encountered the same type of the popup message when i am opening IDT app in SAP. It has been resolved after reduced below value
Option Name: _JAVA_OPTIONS
value: -Xms512M -Xmx1024M ( Previously -Xmx2048)
There could be many possible causes for this error. It could be that compatible mode is not selected in windows 7 , path or eclipse.ini problem.
I am able to solve same issue by specify the -vm C:\Program Files\Java\jdk1.6.0_45\bin\javaw.exe in eclipse.ini.
