问题 I'm in the process of converting my projects to OSGI bundles using maven and eclipse. Maven builds the stuff just fine, only I get the above error now within Eclipse. How can I find out which project causes this? Is there a special view or something? How can this happen, I would expect that maven can detect cyclic dependencies as well?

问题 Apache Karaf is a sub project of Apache Felix. It is defined as "a lightweight OSGi container". I don't understand when should I use the heavyweight and when to use the lightweight.

I still know that Equinox is Eclipse's implementation of OSGi. I read in some articles that eclipse rcp is also based on Equinox. So where is the difference between the target platform you have to choose in a new Eclipse Plugin Project? Best regards 回答1: It is about the environement in which the module you

问题 While using a OSGi Platform on Android i got this errormsg: Fatal signal 7 (SIGBUS) at 0x595302e0 (code=2) I don't think that my app needs that much space in memory or need a lot of computation power. Its just the OSGi Platform with 20 Bundles. My app is always restarting after that. Any ideas ? 回答1: Even I too found a similar problem and happens to be (code=128) with about fault. Seems to be a data alignment error. To solve this issue, I tried putting a code something like this: *Data = (

问题 I have a modular application which uses OSGi framework. Here I'm using org.eclipse.equinox.common_3.4.0 OSGi container. So now the application is already running with all the osgi bundles installed and active and I am displaying all the active OSGi bundles on the UI, by looping though a hash map, based on some action. Now the requirement is, while the application is already running, I want to instal a new OSGi bundle, from a file system, by giving this new bundle to the application's OSGi

问题 There are two main approaches when developing an OSGi application with Maven: POM-first and MANIFEST first.

To be more specific, I would also like to know how it relates to: Maturity of toolset Vendor independence Development ease (which includes finding people who can do the development on the tooling) Compatibility Avoiding ClassNotFound Avoiding manual work 回答1: At present this is what I can
