Windows Java VM vanishing

[BirdyBlue]

Hi can anyone help me with a problem that has only arisen a few days ago. I have Java 1.5.etc, as well as the selection for VM in three tick Boxes, with a main tickbox to toggle between 1.5.etc and VM. All the VM reference has gone, and my appplications run even without the 1.5.etc being ticked. I unticked it and they still ran.? Can't find any reference at all from Microsoft. Have I stepped into something nasty? Er complete wipe? I hope not. HELP.

Can you provide a little more info. What OS? What do you mean by "as well as the selection for VM in 3 tick Boxes"?
Is that in Intermet Explorer?

1. As I can make out from your query, you've updated the options related to Microsoft VM in the Internet Explorer, Tools -> Internet options -> Advanced. Changing these options should not make visible difference during normal operations. The following are the options you see:
i) Java console enabled: is only useful for testing of web Java programs - relevant if you're a web site designer.
ii) Java logging enabled: just creates a log of Java activities. Relevant and useful for debugging your java based web pages and also for managing/tracking security.
iii) JIT compiler enabled: A compilation mechanism for java programs in the web pages.

2. If you want to completely disable Java, go to Tools ->Internet Options -> Security. Click the Custom Level button, scroll down the list, and locate Microsoft VM - Java Permissions.Select Disable Java. This will disable Microsoft VM.

3. If you also have the Sun JVM, you'll see a section Java (Sun) in Tools -> Internet Options -> Advanced Tab. If a Microsoft JVM is also available, there is a section called Microsoft VM. To enable Sun's Java, turn on the checkbox labeled Use Java 2 v1.5.xxx for <applet>.

4. Even when the Sun JVM is being used, in the Microsoft VM section, the option for the JIT compiler (ref. 1-iii above) remains selected. Also, under the Custom Level of the Security tab (ref 2 above), the Microsoft VM section remains with High Safety selected. It is advised that you don't change Java permissions to Disable Java option - it most probably will disable the Sun JVM also!

What do you mean by 'items to do with MS Java VM'? Are you saying that the three items under Tools -> Internet options -> Advanced: Microsoft VM have disappered? Can you give a screen shot of what you see?

There is a difference between Sun Java and Microsoft VM Java. My Microsoft Java VM is missing, if you still don't know what this is please leave this alone until someone may
