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 just had the same problem on Windows 7, 64 bit. I reinstalled Java 32 and Java 64, and Eclipse, but it did not fix the problem. I found that in eclipse.ini the Dosgi.requiredJavaVersion was 1.5, so I changed it to Dosgi.requiredJavaVersion=1.6.0_25. In the Environmental variables I added to the PATH %JAVA_HOME%\bin;C:\Program Files (x86)\Java\jdk1.6.0_25\bin.
These changes fixed my Eclipse problem.
