Hello,

I would like to load plugins dynamiclly when I launch my application, and
unload them when I quit it. These plugins are not .jar but directories. I
use jaas to know if I load or not them.
How can I load and unload these plugins?

Regards,
David.

Normally you use OSGi and your BundleContext ... see
org.eclipse.ui.tests.dynamicplugins.DynamicUtils in the
org.eclipse.ui.tests plugin for an example. OSGi doesn't distinguish
between a directory plugin and a jar plugin.

See http://dev.eclipse.org/viewcvs/index.cgi/ to view the eclipse source
on the web.

Hi,
now I can load my plugin, as it appears in the "Plug-in details".
Nevertheless, I have a ClassNotFoundException for the class which open my
editor, and my editor doesn't open.

What can be the problem?

Thanks,
David.

pde depends page.

I think the problem is that I don't start my installed plugin. But when I
try to start it, I have : "The activator AAA for bundle BBB is invalid"
error message.

Can anyone give me suggestions about this?

Thanks,
David.

In theory installing the plugin should make its plugin.xml available so
editor descriptors and other registry elements show up.

Eclipse will start the plugin (assuming you have auto-start or lazy
start set to try and singleton:=true in your MANIFEST.MF) automatically
for you.

if you specify your activator in you MANIFEST.MF, then your plugin has
to have access to the .class file from the root. Also, is the stack
trace for your invalid error? Usually it has a "Caused by" in it, for
example having your start(BundleContext) method throw an exception would
kill your plugin.

Hi Paul,

My plugin is "Eclipse-LazyStart: true", but it doesn't start. I can see it
in my RCP, but I can use it. When I try start method on my bundle I get a
BundleException. Moreover the used class for Activator is a internal
class, and I acces it with : Bundle-Activator:
package.MyClass$InternalClass.

What can be the problem for a BundleException?

Thanks,
David.

Paul,

When I export my plugin as a "Deployable plugs-in and fragments", I get a
jar file. And I can load this plugin and use it without problem.
Nevertheless, lots of my plugins are directories and I'm not allowed to
export all my plugins. I use the example of "org.eclipse.ui.tests", but I
can't load a "directory" plugin.

Have I forgotten something?

Thanks.

You can load a directory plugin or a jar plugin ... you won't be able to
use this method to load a workspace plugin project, however. Is that
what you are trying to do?

Hi Paul,
Thanks for your help, I am trying to load a plugin from my workspace. Now
I can load directory (exported from my workspace) and jar plugins.

Thanks,
David.
