    Greetings;

    Your question is sketchy. Although you can search Java Damage.
    Here is a bit that may help otherwise you could go to Sun Micro Systems to get some info.
    Java-applet normally need a lot of system resources, to be interpreted and executed. Bad-willed applets or just bad-programmes applets can consume resources in rude or malicious ways, so that a lot of or all the CPU or memory resources of your computer are consumed, slowing your computer down to a locking state, where your machine hangs..
    In earlier JAVA-versions, there was a bug in the Verifier ( a part of Java's runtime system, which checks if applets adhere to the Java safety rules ), which allowed applets, to delete files or do other damage. Fixed in JDK 1.0.2 and in Netscape Navigator 2.02
    Malicious Java applets can generate and execute raw machine code, meaning those applets can perform any action that the user, running this applet via his WWW-browser, can legally perform ( e.g.: read, delete or corrupt files ).

    Hi, Just wondering....by any chance did you get a virus alert message through email about a supposed virus that asks you to delete a file named jdbmgr.exe- I know this has been around for a long time, and deleting the file is not supposed to cripple anything for normal home PCs, but if you do Java creation, like for webpages, it might....the fix is to reinstall Java Virtual Machine, if you recall specifically deleting that one file...due to a virus message concerning the jdbmgr.exe file. It is a hoax, lots of people do what it says, though, and friends send it to friends...so it goes around a lot.

    Hi, Thank you Tony for that- much easier than downloading Java again- I forgot it is part of the windows install.
    Always take a look at your antivirus program's website for virus alerts when you get an email from a "friend"- people forward these things without checking up on them. Symantec, for instance, makers of Norton AV, always have a list of the latest hoaxes so you can check things out.

    Statemgr is a Windows Millennium thingie, which means that you won't have it.

    Be sure to follow the directions for Windows XP

    Also, it's not a vital file, unless you use Microsoft Visual J++ 1.1 to develop Java programs.

    If you're having problems restoreing it, just PM me with your e-mail addie, and I'll send you the file.

    All you'll then need to do is unzip it to your Windows\System32 directory.
