Hi, I have a basic doubt in Applets. If I run a applet from browser, then the memory is taken from the browser memory or seperate process memory is used by the applet. Thanks in Advance. Cheers, Ravi. > Hi, > I have a basic doubt in Applets. If I run a applet from browser, then > the memory is taken from the browser memory or seperate process memory > is used by the applet. Probably implementation specific. - Oliver You mean implementation on browser or OS specific > implementation on browser or OS specific Yes. My doubt is wheather it depends on browser implementation or OS implementation or it depends on both. > My doubt is wheather it depends on browser implementation or OS > implementation or it depends on both. To get a specific answer you need to ask a specific question. Why is this information important to you? What specific OS, browser and JRE version are you interested in? [say "all" and you're likely to get a "depends" answer again...] Remember to tell us why is this information important to you. I want for InternetExplorere in Windows OS. This is important for making a decision for developing the product on Applet or Stand Alone Java Application > I want for InternetExplorere in Windows OS. > This is important for making a decision for developing the product on > Applet or Stand Alone Java Application Does it matter? If you run a java application in a JRE, it will need some memory. If you run an equivalent java applet in IE, it will need the same amount of memory. Why should you care if the browser is involved in the allocation of that memory, or not? Thanks for following it. Now I hope you got that question correctly. Why because The applet should not disturbed other application in the opened in the saem browser or other browser. > Thanks for following it.

What you really want to know is how several applets may affect each other? Specifically when it comes to memory allocation. I'm afraid I wouldn't know, but there's bound to be someone around who does. >> Thanks for following it.

Ravi, you could try an experiment. Put two applets on the same page which use the same static variable. If a change in the static variable of one applet affects the second applet, then you know that they are sharing JVMs. If not, then you don't know (maybe they're not sharing, or maybe they're sharing, but the JVM is being sneaky and detecting what you're trying to do and circumventing it). - Oliver > Ravi, you could try an experiment.

If they do change together then you know they are sharing classloaders within the same JVM. If they do not change together then you know that either that browser is not using a Sun JVM (or something derived from it), or that they are sharing a JVM but using different classloaders for each applet. The Sun JVMs do not allow more than one JVM to be created in the same process. At least that's the case for JSE, what happens on phones, and so on, with not-necessarily Sun JVM implementations, is anybody's guess. -- chris Free MagazinesGet these publications absolutely FREE for up to 12 months.
