Eclipse debugging Java calls the MATLAB program 7.17dll cannot find the problem

After multiple searches, this problem was originally very simple. In the environment variable classpath, configure c: \ MATLAB \ r2012a \ toolbox \ javabuilder \ jar \ win64 \ javabuilder. Jar

Note that if the entire environment is 64-bit, it must be a correct version.

After the Eclipse project is called, The DLL cannot be found;

I keep searching, but I always feel that my configuration is the same as that provided on the Internet;

In the end, I accidentally found that my eclipse was a 32-bit version, and the 32-bit version could not load 64-bit DLL. so I couldn't find anything else!

Switch to 64-bit eclipse, and finally get it done !!!
