Hi Bastian,
The attach API is in the JDK/lib/tools.jar. So you will need to set the
classpath to include tools.jar (e.g. java -classpath
$JDK_HOME/lib/tools.jar YourApp).
You can refer to the example described in Alan Bateman's blog:

Hope this helps.

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
