Attachment to a running virtual machine failed

Question

I get the error message "Attachment to a running virtual machine failed" when trying to instantiate my active x bundled java bean.
The steps I took to create it are:
javac Person.java
jar -cvfm PersonBean.jar person_manifest Person.class
set JRE=D:\Applications\JavaSoft\JRE\1.3.1_01
set classpath=%JRE%\lib\rt.jar;%JRE%\lib\jaws.jar
java sun.beans.ole.Packager
Then I answered the questions on the packager.
When I try to create the bean from inside my application, I get an error dialog with the title "Java(TM) Plug-in 1.4 Fatal Error".
When I try to create MSCal.Calendar in my application, all is well.
Anyone know what is happening?

Answer 1

If you run the packager, try not to register the
newly created type library (*.TLB) immediately,
but let the packager create the registry instructions
(a *.REG file).
Look at the *.REG file and check all references to
virtual machines. Since you are using the packager
from 1.3.1, probably the virtual machine (path for beans.ocx etc) points to the 1.3.1 JRE instead of the
1.4 plugin.
Make sure, all references to the virtual machine are
linked correctly to 1.4 and reregister your TLB.
Hope that helps and please let us know if you were
successful, as this would indicate that indeed, beans
packaged with the packager from 1.3.1 can run in the
1.4 plugin. Sylvia
