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 resolved it by installing 32 bit JDK and editing eclipse.ini to point to 32 bit jdk . Added -vm C:\Program Files (x86)\Java\jdk1.7.0_71\bin at the end of eclipse.ini file.
Note: I have my JAVA_HOME pointint to 64 bit JDK
