问题 I'm using PAX-URL to launch a Felix based project from Eclipse. I use the assembly protocol to avoid having to pre-pack my bundles. In the project, felix is started using the felix.jar and a config.properties which includes felix.auto.start.1=assembly:foo/bar/classes to start one of my unpacked bundles. The trouble is, felix doesn't know about the pax-url protocols until after it's finished reading that config file, so I get an "Unknown Protocol: assembly" error. What am I doing wrong? Is it

问题 I'm a complete newb at this so I apologize in advance. I'm trying to create an OSGi component that simply shows a hello world message and is configurable via the input from felix. Then spits it out on a jsp page. I'm using scr annotations to help do this. Here is my java code package com.training.cq5.trainingApp; import org.apache.felix.scr.annotations.Activate; import org.apache.felix.scr.annotations.Component; import org.apache.felix.scr.annotations.Properties; import org.apache.felix.scr

问题 I have a bundle, with an activator declared. This activator create a JFrame and show it. Running on Eclipse as Plugin project it works fine. When I put on Felix it doesn't work anymore. It shows: java.lang.NoClassDefFoundError: com/griep/ui/MainFrame But MainFrame is located in the same bundle the activator is, as a public class, of course. I don't understand why the classloader isn't finding the class. Anyone knows what is happening? 回答1: Make sure you import the javax.swing package into

问题 I have successfully managed to start Apache Felix from code and register an own Bundle. Following relation between OSGI-projects is needed: [OsgiInterface] -- provides interfaces. [OsgiModuleA] -- (bundle) provides an implementation of those interfaces. knows [OsgiInterface] [OsgiUsage] -- makes use of one or more bundle. knows [OsgiInterface] and [OsgiModuleA] Now I have problems registering a service which implements an interface. I would guess that my entries in manifest.mf files are wrong

问题 I have defined four bundles: bundle 1 : export package x version 1 bundle 2 : import package x ver [1,2] and export package y;y uses x bundle 3 : export package x version 2 bundle 4 : import package y and also import package x version 2 Using apache felix (distribuable binary), I found that I should manually impose to not resolve (or start) the bundle 1 and then bundle 2 before starting the bundle 3 (otherwise a uses constraint problem appears because bundle 2 will use package x version 1 and

问题 I tried implementing my own class loader based on some examples. However, I think it is not working as expected ( unable to reload Jar file etc. I see few references of recommending using OSGI or Apache Felix for handling Jar file loading. Is there any examples of loading Jar, instancing a class from the Jar? More details on what I am trying to accomplish..I have a Java command line application that essentially continuously runs. I want it to be able to reference JAR files dynamically at

问题 Is there any example of how to configure/install Apache Felix File install? In official website, it has been mentioned you need to configure properties etc. But no way they have mentioned where you need to put those configuration properties, how to set it up etc. I have downloaded org.apache.felix.fileinstall-3.2.6.jar file and I have felix framework installed. Now I am not getting where should I put those configuration properties so that file install will read that. Can anyone guide me on

问题 I downloaded Postgresql-9.2-1003.jdbc3.jar and put it in felix\bundle directory. My program accesses Postgres table EMP and prints it. I am trying to do it in Felix OSGi server. There are two parts of my program: Part-1 program which simply connects to Postgres JDBC driver and opens the database: package com.myprogram.myemp; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.Statement; import org.postgresql.Driver; public class

问题 I am looking for a way to (re)deploy an exploded bundle (meaning not jarred but in a folder) to a running Apache Felix OSGi container from within Eclipse, preferably using a launch task. I found this question, which has an answer that comes close but it depends on typing commands into a Gogo shell, which is not convenient for long-term development use. I'd like to use Eclipse's launch task mechanism for this, but if there are alternatives that are equally fast and convenient I am open to that

问题 Good day. I am trying to get the benefits of OBR in my application. I took Karaf Cave (4.0.0) as OBR implementation and org.apache.felix.bundlerepository (2.0.4) as OBR client. I successfully configured the repository itself but I can't properly use it. The problem is: when I install the bundle via OBR and all its dependencies are already installed in OSGI runtime, it is installed successfully. But if some of the requirements are missing, I got an "Unsatisfied requirements" error, which is
