unable to call the java function in my .jar

In eclipse, the .java is in MyProject->src->Mypacket->myclass.java

I use export to export the jar and put in in to the root folder of matlab

then I use the javaaddpath and can see the path below DYNAMIC JAVA PATH using javaclasspath

But I can call my function

methodsview ReverseImageSearch also return

No class ReverseImageSearch can be located or no methods for class

Hi Chan,

I can replicate your issue if I load my collective.jar file and try to view the methods of the Radix2FFT java class:

javaaddpath /Users/geoff/Development/java/collective.jar
methodsview Radix2FFT

Error using methodsview (line 100)
No class Radix2FFT can be located or no methods for class

The problem is that I am not making use of the package name. If I list the contents of my jar file (outside of MATLAB, in a terminal window), I see that:

>> jar tf collective.jar

META-INF/MANIFEST.MF
com/geoff/dsp/Radix2FFT.class
com/geoff/dsp/Other.class

So in order to list the class methods (or even instantiate an instance of the class) I have to type:

methodsview com.geoff.dsp.Radix2FFT

Please try the above and see what happens.
