Maven Web Project with Apache Felix Plugin

问题

What's the best way to create a simple osgi (deploying into virgo server) project using maven, to create a war structure with pom.xml maven descriptor?

A Structure target is

*.jsp
*.html
META-INF
MANIFEST (OSGI-CONFIG)
WEB-INF
  classes
  lib
  web.xml

Then when I create a project

This is my pom.xml

project properties

<groupId>com.aaaa</groupId>
<artifactId>first-maven-virgo-project</artifactId>
<version>1.0.0</version>
<packaging>war</packaging>

Felix Plugin

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
        <supportedProjectTypes>
            <supportedProjectType>war</supportedProjectType>
        </supportedProjectTypes>
        <instructions>
            <Export-Package>com.roshka.servlet</Export-Package>
            <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
            <Bundle-ClassPath>.,WEB-INF/classes,{maven-dependencies}</Bundle-ClassPath>
            <Embed-Directory>WEB-INF/lib</Embed-Directory>
            <Embed-Dependency>*;scope=compile|runtime;</Embed-Dependency>
            <Embed-Transitive>true</Embed-Transitive>
            <Web-ContextPath>/hello</Web-ContextPath>
            <Webapp-Context>hello</Webapp-Context>
        </instructions>
    </configuration>
</plugin>

But, when I execute mvn install the package does not create the MANIFEST file, to package into METAINF folder.

What's the wrong with my felix project? What's is the typical pom.xml template to create an OSGI BUNDLE , and WAR OSGI BUNDLE?

p.s. if I change WAR TO BUNDLE into Packaging Maven descriptor, the JAR generated works OK, with MANIFEST generated OK. But it is not WEB Structure.

My question has been resolve with the next pom.xml

回答2:

There is an answer from IBM to be found here which describes the process step by step. A script could be developed to create a bundle given a war, I have written one in java, invoked as a build step.

One crucial difference is that the IBM steps leave the finished product as a jar, whereas jrey leaves his as a war file. This is possibly because the IBM steps might lead to further CICS bundling, which requires jars as far as I am aware, at least when using the RAD environment.
