Unable to locate Spring NameSpaceHandler - Spring's mvc-basic in equinox using MANIFEST.MF similar to web-console Spring DM sample webapp

Question

Trying to deploy Spring's mvc-basic in Equinox container.

Brief error (full below):

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring   NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context]
Offending resource: ServletContext resource [/WEB-INF/spring/app-config.xml]

mvc-basic's app-config.xml: https://src.springframework.org/svn/spring-samples/mvc-basic/trunk/src/main/webapp/WEB-INF/spring/app-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"&gt;

    <!-- Scans the classpath of this application for @Components to deploy as beans -->
    <context:component-scan base-package="org.springframework.samples.mvc.basic" />

web-console's applicationContext.xml: https://src.springframework.org/svn/spring-osgi/tags/spring-osgi-1.2.1/samples/web-console/war/src/main/webapp/WEB-INF/applicationContext.xml

changed slightly (i.e., changed spring-context.xsd to spring-context-3.0.xsd) to match mvc-basic's app-config.xml (patch is linked below):

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd"&gt;

    <!-- OSGi package admin service reference -->

Thank you!

EDIT: Just tried with Spring DM 2.0.0.M1 which uses Spring 3.0.0.RC1 out of the box.

Relevant .bundles files are: spring-osgi-2.0.0.M1.bundles http://gist.github.com/633280

spring-osgi-2.0.0.M1-with-mvc-basic.bundles http://gist.github.com/633283

2.0.0.M1 reference source: https://src.springframework.org/svn/spring-osgi/tags/spring-osgi-2.0.0.M1/samples/web-console

Unfortunately, the 2.0.0.M1 org.springframework.osgi.* jars are not available (to my knowledge) in any bundle repositories, so you must first download and compile spring-osgi-2.0.0.M1 from this subversion repo: https://src.springframework.org/svn/spring-osgi/tags/spring-osgi-2.0.0.M1

Answer 1

Turns out the OsgiBundleXmlWebApplicationContext is required. Helpful references: http://static.springsource.org/osgi/docs/current/reference/html/web.html http://static.springsource.org/osgi/docs/current/reference/html/web.html

Retrieve relevant patch:

wget http://gist.github.com/raw/648295/452aaeeceed8fae6b9a4d035a5c2d2ad939f65bf/mvc-basic-osgi-works.patch

Command to start mvc-basic using OSGi:

svn checkout https://src.springframework.org/svn/spring-samples/mvc-basic/trunk --quiet && cd trunk && patch -p0 < ../mvc-basic-osgi-works.patch && mvn clean install -DskipTests && bash run.sh

This assumes that you have downloaded mvc-basic-osgi-works.patch into the current folder.

Some things still don't seem to work, e.g., ${pageContext...} tags, but other than that seems to work.
