Error using fminsearch: No class * can be located on Java class path

Hello,
I'm experiencing some problems when executing fminserach with R2012a 32 bits. Always when I use the plotting option @optimplotfval the function crashes with the following error:
- Error using javaMethodEDT
- No class com.mathworks.toolbox.optim.OptimGUI can be located on Java class path
- Error in callAllOptimPlotFcns (line 78)
- optimtoolGui =
- javaMethodEDT('getOptimGUI','com.mathworks.toolbox.optim.OptimGUI');
The problem appears also when trying to do the example in the documentation with the function onehump (you can search for this in the help). The error is new to me (it worked before) and one colleague with a different computers gets it too.
I hope you can help me on solving this problem.
Bye Dr. Martin Chavez

This code works for me:
x = fminsearch(@(x)sin(x(1))*cos(x(2)),[-2,1],optimset('PlotFcns',@optimplotfval))
x =
-1.5708 0.0000
Perhaps you should call
rehash toolboxcache
If the problem persists, I suggest that you contact technical support.
