if we add a few other things to your code, your code does not work. The things I need to add are event listeners and a menu bar. These become necessary as several internal frames need to be generated and organized in Desktop pane.
I tested your code with some standard code from Sun Java tutorials and other well tested code. I get the same error. I could not post this question on other forums (not jReality) as the question involves knowledge of jReality and jrworkspace.
I put below one of the modifications to the code.
I shall really appreciate your help in this.
