I developed the whole web based project using Swing 1.1.1 and used JDK =
1.1.2 plug for deploying it in the web.
but when in the final testing, I found severe memory leaks in Plugin =
1.1.2
when I reload my applet 9 times there is out of memory error.(Actually I =
popup the JFrame from the applet, I dispose that frame in its destroying =
event)
I tried the same thing with using Internet Explorer 4.0 VM atleast 50 =
times and every thing is working fine. it means that there is some =
problem in plugin.
I visit the web site of sun and see this issue in Bug prade, but Sun =
claim that it is fixed and closed. but we have no new version of plug-in =
so what can I do now.

I have second alternative to use JDK plugin 1.2.1 instead of JDK plugin =
1.1.2, but it has also one severe problem
if user in Windows 95/98 uses non default cursor(e.g. Plus theme cursor) =
lightweight components don't update and the application looks very =
buggy. Sun also claimed that it is fixed but not new version =
available.(I am waiting for JDK 1.2.2 plugin hope fully its work fine)

its means that for the time being there is no single plateform available =
for sun, to use Java Swing applets in internet(both 1.1 and 1.2 has =
bugs)
If I forget plugin and use browser native VM then the applet size is =
about 2MB this is certainly unexpectable for client.

WHAT CAN I DO FOR THIS PROBLEM, JUST THROGH JAVA AWAY FROM MY DESKTOP =
AND OUR COMPANY AND ALSO LOOSE OUR 4 MONTHS PROJECT HARDSHIP. OR WAITING =
FOR MAIRICAL.

I am waiting for your people reply.... and suggestion to overcome this =
problem
