First, check you eclipse.ini (even a space at the end of a line can prevent eclipse from starting)
Second I am surprised to see java* file in your Eclipse distribution.
You shouldn't' have those, and instead refer to the right java (64 bits) in your eclipse.ini.
In both case, see this eclipse.ini as a good example.
Check also the <workspace>/.metadata/.log (error log file).
I just added it there because it was asking for it, supposedly the best way it to put it in the PATH.
If eclipse is "asking for it", that means your current java installation is not part of the PATH. It need to be reference from the eclipse.ini file.

In any event, don't copy any java files around.
Used in your eclipse.ini a path like:
-vm
C:/Prog/Java/jdk1.6.0_21/jre/bin/server/jvm.dll
Do you have the 64-bit version of Java? http://www.java.com/en/download/faq/java_win64bit.xml
