attach mode failed

[Pierrick MOLERA]

Hi,
thankyou very much  Julien for this great Jug at Montpellier. :)
Now I want to try CRaSH with my desktop application.

I've started my application and get the pid with the jps command.
So when I run crash.bat pid : I get the following exception :

java.util.ServiceConfigurationError: com.sun.tools.attach.spi.AttachProvider: Provider sun.tools.attach.WindowsAttachProvider could not be instantiated: java.lang.UnsatisfiedLinkError: no attach in java.library.path

What step I've missed for this attache mode ?

If I want embedded CRaSH in a desktop application, what do I need to do exactly ?
thank you in advance for your help.

Regards,
Pierrick

Glad you liked it!

I have to confess attaching has not been tested enough on Windows platform. You are not running into a CRaSH issue per se but instead a “crash.bat” issue.

Henri Tremblay at Devoxx Hackergarten provided a pull request to improve that but I had no time to merge / verify it.

Can you try to apply this patch to crash.bat and see if it improves things ?

Basically three choices:

1/ use the org.crsh.standalone.Bootstrap class like the org.crsh.standalone.CRaSH does (https://github.com/crashub/crash/blob/master/shell/src/main/java/org/crsh/standalone/CRaSH.java)

2/ use org.crsh.standalone.CRaSH class . 

3/ embed CRaSH in Spring and bootstrap Spring : http://www.crashub.org/1.3/reference.html#_embedding_in_spring

I think some people have done that recently in this list, perhaps they can share their experience too!

Pierrick

Thank you very much again,

I will check your links, and I will post if I find an attach mode solution

For the embedded mode I will try this bootstrap class.

Hi Julien,

I've fixed my system path and I've put my jvm path in first.

So, now I've got a new error with the attach mode under Windows :

thanks, I think I need to bootup a windows OS and figure out by myself (with my limited windows skills :-) )

I will try to spend some time on that during the week end!
