How to dynamically attach using JRE's java.exe?

[Bastian Helfert]

Hello everybody,

I apologize for posting my question to this mailing list, but is there
anyone who can help me, please?

How can I execute

   VirtualMachine.attach(pid);

by using the java app launcher of the JRE for Windows (i.e. instead of the
java.exe that ships with the JDK)?

I have tried to set:

   -Djava.library.path=%JDK_HOME%\jre\bin\attach.dll

and also


-Dcom.sun.tools.attach.spi.AttachProvider=sun.tool.attach.WindowAttachProvider

which possibly is nonsense, but I still receive the error:

   java.lang.UnsatisfiedLinkError: no attach in java.library.path
   Exception in thread "main"
com.sun.tools.attach.AttachNotSupportedException: no providers installed
       at
com.sun.tools.attach.VirtualMachine.attach(VirtualMachine.java:190)
       ...

Has anyone a solution to this (besides using the JDK's java.exe)? If so:
What libraries / properties do I need to provide / set and how? What else do
I need to do and how?

Thank you very much in advance,
Bastian
