Deploying a WAB with Spring Security 3.0.5 in bundle-classpath [message #756334]

I'm bundling my maven project as a wab, using the maven-bundle-plugin. The wab contain spring-security-config3.0.5.RELEASE in WEB-INF/lib folder.

When start the bundle on the osgi shell, I get the following exception.

org.springframework.beans.FatalBeanException: Class [org.springframework.security.config.SecurityNamespaceHandler] for namespace [www.springframework.org/schema/security] does not implement the [org.springframework.beans.factory.xml.NamespaceHandler] interface

I did a clhas through the shell on the SecurityNamespaceHandler class and my module seems to be the only one which has the class

I did a clload on the same class again and this time, the bundle started without any exceptions and was put to the ACTIVE state.

Questions I have,

1. Virgo uses spring 3.0. Does it have an older version of SecurityNamespaceHandler class in its path? The reason I ask this is because, digging through some code, it seems like the xmlbean factory looks for the class in a specific class loader. I'm not packaging the spring modules (packaging only the security modules) and use spring services provided by virgo. If that is the case, the class in my bundle class path may not have been loaded.

2. If Case1 is true, should i package spring with my app and stop using the provided spring framework?

I think I have an idea why you are getting this exception but to be sure I would need to test it quick.

Can you please post your web.xml and MANIFEST.MF for the bundle in question. Just to make sure that it is not something with configuration. Also, where do you have spring configuration files? In META-INF/spring or outside of that directory?

Regards,
Dmitry

Hi Dimtry,

I have attached my web.xml

I dont have a MANIFEST.MF I'm just letting the framework configure my app.

Some of my configurations like applicationContext.xml are in the METAINF/spring folder. Others like webmvc-config are not.

With web applications you have to let web application context load your config. Move all your configuration outside of META-INF/spring and configure "contextConfigLocation" to point somewhere else like "WEB-INF/spring/*.xml". spring-dm extender will ALWAYS look into META-INF/spring to see if this is a spring power bundle and try to create AppContext. spring-dm extender does not know anything about web apps.

See here: http://static.springsource.org/osgi/docs/1.2.1/reference/html/bnd-app-ctx.html#bnd-app-ctx:app-creation
and here: http://static.springsource.org/osgi/docs/1.2.1/reference/html/app-deploy.html#app-deploy:headers

Hope this solves your problem.

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:WEB-INF/spring/applicationContext*.xml</param-value>
    </context-param>

<servlet>
        <servlet-name>tama</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring/webmvc-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

Sorry for the late reply. Thanks for your hint. It works.

Can you guys make a direct mention to this somewhere?, because we were stuck in it for a long time. Or have I missed it?

@Dmitry, Just curious, the idea that you mentioned in your first reply had something to do with this? www.osgi.org/blog/2007/04/importance-of-exporting-and-importing.html

PS: Not being able to post links is painful

There is reference to this issue in the docs 6.4 Form Tags Shared Services WAR.

It is in a bit of a obscure place. Click on the link and look for Note in "Accessing the Service and Types from the WAR" section. It is one of the things that we will have to move to an FAQ section. I will submit and issue to do it.

As for the idea that I mentioned in the first reply - it did not have to do with import/export directly but with the way spring-dm 1.2.x implemented namespace handling. Now that I think more of it - it should not have mattered at all anyway. You are not using osgi shared services model.

Regards,
Dmitry
