Hi,

I am not sure why but I am not able to invoke a static function from =
within a popupmenu plugin. common is another package in the same plugin =
project. I am attaching the code where I am invoking a static function =
of another class Utils. The output only shows "BEFORE".

On debug, earlier eclipse showed me a class not found error, now it does =
not show me anything. I have done a project clean and a full compile and =
the class files are present in the right directory.

Tx Praveen.

I am able to invoke the static method from a regular class as follows. =
So the eclipse JDK has the class path etc. setup. I suspect its some =
tweak I need to make in the plugin execution environment.

Thanks Praveen.

import common.Utils;

public class asd {

public static void main(String[] args) {
Utils.writeToFile("A", "C:\\ad", "QWE.txt");
}
}

I notice that your code doesn't include an import for common.Utils. Is
this just a cut and paste omission?

I suspect its because the plugin is in package plugin.actions and the =
utils class is in common package. common and plugin are at the same =
hierarchy but the execution considers plugin.action as the root and =
looks for common.utils inside it.

I tried adding the bin and src directories to classpath in the runtime =
tab but that doesent help. Any other ideas?

Thanks Praveen.

Praveen,
in the OSGi runtime, your plugin.actions bundle can only load classes
from bundles that it said it required.
What you need to do is for the common bundle to add an Export-Package
for its utils package in its manifest.mf file.
Then plugin.actions needs to either Require-Bundle: common, or
Import-Package: common.utils in its manifest.

Hi Andrew,

I made another hello world plugin with just the same hierarchy of plugin =
and other classes and I am able to access the plugin static method =
without doing an export-Package or a required-Bundle.=20

In my existing project with common, plugin.actions, I added in the =
exported packages tab and the classpath tab. But am still facing the =
same problem

I am not sure what I am missing.

Tx Praveen.

Praveen,
in the OSGi runtime, your plugin.actions bundle can only load classes=20
from bundles that it said it required.
What you need to do is for the common bundle to add an Export-Package=20
for its utils package in its manifest.mf file.
Then plugin.actions needs to either Require-Bundle: common, or=20
Import-Package: common.utils in its manifest.
