How best to maintain an Eclipse RCP plugin target?

阅读更多关于 How best to maintain an Eclipse RCP plugin target?

I have a plugin for an RCP app that uses BIRT. I have a target for building my app which contains only the plugins/features that are required. I recently updated the BIRT plugin versions in my IDE, which created an incompatibility in the design files with previous versions of BIRT. I have the old version of BIRT in my target and need to update to the newer plugins. In the past I have manually updated plugin jars in the target, but BIRT is a complicated platform with dependencies out the wazoo. Is there any utility or way of organizing my target differently that will make this easier to control

Printing with an Eclipse RCP program

阅读更多关于 Printing with an Eclipse RCP program

I am looking for a good, standard way to generate "output" in my RCP programm and print it. This should work as it works on Windows, Mac OS and Linux with the standard print dialog. I am aware of the Birt project, but I could not find any hints about how to implement it within a RCP programm and how to invoke the standard print dialog and how to pass the Birt generated report to the printer.

For that to work, it is

Eclipse RCP: Only one Job runs at a time?

阅读更多关于 Eclipse RCP: Only one Job runs at a time?

问题 The Jobs API in Eclipse RCP apparently works much differently than I expected. I thought that creating and scheduling multiple Jobs would actually cause multiple worker threads to be created, executing the Jobs in parallel unless there was an ISchedulingRule conflict. I went back and read the documentation more closely, and also discovered this comment in the JobManager class: /** * Returns a running or blocked job whose scheduling rule conflicts with the * scheduling rule of the given

阅读更多关于 Restrict permissions to threads which execute third party software

问题 I'm developing an eclipse based application capable to execute third party component (not eclipse-plugin). Each component has a custom descriptor, where are listed permissions (with correspondent motivation). In this way final user can decide if execute it or not. Components are executed in separated threads. How can I restrict permissions to these threads according with the descriptor, without restrict entire application? Thanks 回答1: First of all, you should turn on the Security Manager.
