I would like to get to query Windows Vista Search service directly ( or indirectly ) from Java. I know it is possible to query using the search-ms: protocol, but I would like to consume the result within the app. I have found good information in the Windows Search API but none related to Java.

This...

Hi, I have an Eclipse workbench application composed of many plugins. I'd like to set the about text of the app to reflect the build number. There seems to be a couple of places to do this: - Inside the application's .product file (setting text here doesn't seem to do anything?) - Inside the plugin.xml file of the main plugin (thi...

I wonder how weak references work internally, for example in .NET or in Java. My two general ideas are: "Intrusive" - to add list of weak references to the most top class (object class). Then, when an object is destroyed, all the weak references can be iterated and set to null. "Non-intrusive" - to maintain a hashtable of objects' poin...

The problem is that I want the API to provide a piece of functionality like: javaApi.waitUntilPredicateIsTrue(Predicate<JavaObj> test); My API (in the background) gets hold of instances of Java Obj (via some mechanism, e.g. polling). I want this API...
