I develop and support an application with HTML- sites which contains a lot of Applets (5-25 per site). Sun's JRE: Under Windows2000/XP/IE6.xx the JRE 1.4/1.5 runs only if I set the heap up to initial heap=128MB and maximal heap=256MB from the JRE- Icon in the System Panel. Microsoft's MSJVM 5.0.0.3810: This Engine displays all 25 Applets after the first start, slow down after the first refresh and freeze after the second refresh. After that the IE 6.XX is not longer usable and must be killed with the taskmanager. Who can I tell me how can I tell my WindowsXP that the MSJVM can get more resources? I have a lot (1GB) . If I have an application with only one Applet, the Sun Engine JRE runs in their default, the MSJVM too.

If I have an application with only one Applet, the Sun Engine JRE runs in their default, the MSJVM too. I personally have never used the MS JVM; it supports only JDK 1.1 and even then it apparently has some issues. The behaviour you're seeing with MS JVM doesn't really surprise me. I'm surprised that the Sun JRE won't run the applets using its default configuration; I've run applets of various sizes without having to tweak the plug-in. I haven't, however, tried to run 25 applets at once, which is the likely cause of your trouble. My only suggestion would be to insist on the Sun JRE for running your applets. If at all possible, try to simplify your page to use fewer applets as well. Much of what applets were originally used for (rollover buttons, for instance) can now be accomplished with JavaScript. -- Kevin Dean [TeamB] Dolphin Data Development Ltd. http://www.datadevelopment.com/ NEW WHITEPAPERS Team Development with JBuilder and Borland Enterprise Server Securing Borland Enterprise Server http://www.datadevelopment.com/papers/index.html Please see Borland's newsgroup guidelines at http://info.borland.com/newsgroups/guide.html Back to top Jasper Friese Guest Posted: Thu Jan 19, 2006 6:30 pm    Post subject: Re: IE6/MSJVM freeze Hallo Kevin, thanks for your reply, but my application need (too) many Applets. It is a part from a big process management system. The processes are the background- pictures and the Applets on it displaying the data. A real solution are servlets which can working as GIF- generators, but they are not ready. I do not like the MSJVM too, but my customer love it.

That would require a complete rewrite. JWS would only require a wrapper.
