Re: [ptp-user] Remote Tools search path for the "java" executable

Greg,

I've been seeing an issue on newer machines where the Dstore server is
complaining about the version of java - or isn't finding it (and doesn't
get launched in either case).  I've tried looking at the environment
(through the build mechanism), everything looks sane there, and the
default java in the path is 1.6, both for build and also interactively.
I'm wondering if the issue reported below is related somehow, and also
would like to figure out how to debug this issue better.  Do you have any
suggestions?

Jay

Hi Rodrigo,

Please open a bug. That way we can keep track of the issue.

We could use the RM configuration file for this, but that would mean that
you need to configure a RM to use a remote project, whereas remote
projects are currently independent of the RM framework. I think it would
be better to make this a configurable property of the project.

Regarding the debugger, you can set the gdb location using the SDM
preferences (Preferences>Parallel Tools>Debug>SDM). Note however, that
this setting will apply to any debug configuration that uses the SDM. If
this is too restrictive then it might be better to make this a
configuration option in the debug launch configuration.

Regards,
Greg
