Like what you said, if you run javaclasspath, you will see your jar is there, and when you import, there is nothing wrong. But when you call the classes. it says undefined.

To do this, simply type: "edit classpath.txt" in your Matlab Command Window and after adding your JAR(s) restart Matlab > > Yair Altman > http://UndocumentedMatlab.com Thanks, Yair, Yes, I did that, and I am quite sure classpath.txt is edited and jar files are there. I am using a third party ones, and their instructions is like this also. So, I am still not sure what is wrong. I also checked with other matlab versions, not working either. But if you have time, I can send you the jar file for a test.... /Lei

Feel free to email me. > > Yair Altmanhttp://UndocumentedMatlab.com Hi, I am not a professional consultant :D However I had the same problem and apparently it is because of the version of java being used in your Matlab and in your java code. Make sure they are using the same version. For example I was compiling my code using jdk 1.6 while my Matlab was using jdk 1.5. I changed my main java to 1.5 and then Matlab was able to load the jar file. Hope this helps. Best, Mohsen |
