Access Persistent Property value out side of PropertyPage [message #138064]

I have used the new plugin wizard creatd a plugin with property dialog ( a
subclass of PropertyPage), in it I use the following code to persist a
property.

public class MyPropertyPage extends PropertyPage {

.....
public boolean performOk() {
// store the value in the outputSqlFile text field
try {
((IResource) getElement()).setPersistentProperty(
new
QualifiedName(Platform.getBundle("com.myPlugin").getSymbolicName(),
OUTPUT_SQL_FILE_PROPERTY),
outputSqlFileText.getText());

} catch (CoreException e) {
return false;
}
return true;
}

I need to get the persistent property value outside of MyPorpertyPage,
because the value needs to be available even the user does not open the
properties dialog. How can I do it?

I have searched eclipse help, it says "Persistent properties are used to
store resource-specific information on disk. The value of a persistent
property is an arbitrary string. Your plug-in decides how to interpret the
string. The strings are intended to be short (under 2KB). "

But how do I access the property persisted on the PropertyPage, from
outside of the PropertyPage class?

Thanks a million.

The properties are stored with the bundle. No need to be inside a
property page do access them.

Thank you for the answer!
But now I have to ask you how can I access the bundle, because I wasn't able to find anywhere.

Platform.getBundle("com.myPlugin")

I still have some problem:

Now I set the property in the PropertyPage like this:

((IResource) getElement()).setPersistentProperty(
					new 
					QualifiedName(Platform.getBundle("org.eclipse.emailrecommender").getSymbolicName(), 
					"MAIL_LIST"),
					MailingList.listToString(arrayMailingList));

and I try to access like this:

Bundle b=Platform.getBundle("org.eclipse.emailrecommender");
		BundleContext bc = b.getBundleContext();
		String s=bc.getProperty(Platform.getBundle("org.eclipse.emailrecommender").getSymbolicName());

but I get a NullPointerException at b.getBundleContext();

This either means you have a typo in the bundle name or the bundle
cannot be found.

I solved my problem with this:

IProject[] projects=ResourcesPlugin.getWorkspace().getRoot().getProjects();
for(IProject prj :projects){
    String property=prj.getPersistentProperty(PROPERTY_NAME);
}

And I can get all the projects which has my property set!
(It's more or less what I wanted)

Thanks Dani for the help!
