For firefox it is taking just 5 secs to display 1295 records and IE more than 2 min. How can I handle this performance issue? Hi,

I think that it would be nice to possibly consider laying on top of AWT, as well as SWT. What are others thoughts along this line?

In my application i have use the concept of card deck. So many pages in my application are loded but unload only when the whole application is unloaded. Is there any way to handle memory leak rather than in the onunload event. hi,

I published an article recently on a related topic at http://www.infonoia.com/en/content.jsp?d=inf.05.07 It was also referred to at theserverside.com and eclipsezone.com I think JS-SWT could be very interesting in relation to what I call RSP (Rich Server Platform). Please email me to discuss. Where are you located? Kind regards, Wolfgang Gehner Hello Josson,

It seems that inner classes compiling is not fully implemented. I tested the compiler on inner class issue by testing on java.util.* (HashSet, HashMap, ...).

Actually, there are other defects in Java2Script, which will require more efforts to overcome. 1. Thread in Java will never be implemented in pure JavaScript (Some alternatives should be invented to imitate the Thread activites: waiting, sleeping, blocking, and so on) 2. Primitive types: byte, short, int, long, float, double are all treated as Number Objects in JavaScript 3. Regular Expression is not implemented yet. 4. Array with different multiple dimensions is not distinguished in the metho invocation. Example, "int[][] a" and "int[] a" is all treated as "Array a". 5. Others...
