Question

in eclipse plugin i have two plug-in which are used there own class loader to load classes.. 2 main problem
Case 1:- in 1st Plugin i made a singleton class and when ever i want it to set some property form another plugin (because singleton so every object will change same object) but it can t do same as i accept.. because for every class loader there its own singleton object....
Case 2:- in 1st or 2nd plugin i made a class with a single staticproperty and through another plugin i want to access that property...
i want to access that property but i can t because every class loader there own name-space that means there own static variable...
what i did is :-
1. i make a class in 1st plugin with a static String variable
2. through 2ND plugin i set the value of that property
3. when i use it through 1st it how its value null and if through 2nd the is show that what i set previously . Now the problem is how i can access those property...in case 1 and case 2

在Eclipse,每个OSGi bundle(plugin)都有自己的班轮。与其他包裹相比,它们没有等级。

但是,如果你在plugin1中界定一个静态变量,并希望从plugin2中加以利用,那么,如果是plugin2, MANIFEST,的话,你将具备以下标准: MF:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: %Plugin.name
Bundle-SymbolicName: org.eclipse.ui.examples.propertysheet; singleton:=true
Bundle-Version: 3.2.200.qualifier
Bundle-Activator: org.eclipse.ui.examples.propertysheet.PropertySheetPlugin
Bundle-Vendor: %Plugin.providerName
Bundle-Localization: plugin
Require-Bundle: plugin1
Bundle-ActivationPolicy: lazy
Export-Package: org.eclipse.ui.examples.propertysheet
Bundle-RequiredExecutionEnvironment: J2SE-1.4

<代码>Import-Package和Require-Bundle是正确的方式,只要捆包也使用,即可从一个捆绑到另一个捆锁的班级。 Export-Package
