Custom context class [com.springsource.server.web.dm.ServerOsgiBundleXml WebApplicatio

[cmoulliard]

Hi,

When I deploy my WAR in Spring DM 1.2.0-m2, I receive the following error :

It should be possible to deploy a standard WAR file to dm Server without having to have anything dm Server specific in your web.xml: e.g., there should be no need to specify a custom context class.

Have you tried deploying your WAR without specifying the dm Server type as a custom context class in your web.xml?

[cmoulliard]

Hi,

Do you mean "removing the following lines from my web.xml file"

<context-param>
<param-name>contextClass</param-name>
<param-value>com.springsource.server.web.dm.ServerOsgiBun dleXmlWebApplicationContext</param-value>
</context-param>

?

By the way, I have tested my WAR without this context-param but I have the following error :

Hi,

Do you mean "removing the following lines from my web.xml file"

<context-param>
<param-name>contextClass</param-name>
<param-value>com.springsource.server.web.dm.ServerOsgiBun dleXmlWebApplicationContext</param-value>

?



Sorry, I should have been clearer. Yes, that's what I meant.



By the way, I have tested my WAR without this context-param but I have the following error :

[2008-12-08 15:47:40.088] async-delivery-thread-1 catalina].[localhost].[/reportincident.web-1.0-SNAPSHOT].unknown E Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListe ner

Aah, ok. I'd guess from that, that you're using Spring DM in your camel-context.xml file. Is that the case? Could you post your camel-context.xml file to help narrow things down?

[cmoulliard]

Here is the Camel (Spring) xml file :

KR,

[Andy Wilkinson]

Thanks. I think I know what the problem is now.

I can see from your application context that you're using a Spring DM, and that you're importing a service from the OSGi service registry. This means that your WAR is, in fact, a shared services WAR (http://static.springsource.com/projects/dm-server/1.0.x/programmer-guide/html/ch04.html#architecture-shared-services-war).

In a shared services WAR file, it's correct to have the custom context class specified as support for shared services WARs is dm Server-specific. This means that you should have the following in your web.xml:



<context-param>
<param-name>contextClass</param-name>
<param-value>com.springsource.server.web.dm.ServerOsgiBundleXml WebApplicationContext</param-value>
</context-param>


So, we need to step back a bit and look at the original error that stated:



Custom context class [com.springsource.server.web.dm.ServerOsgiBundleXml WebApplicationContext] is not of type [org.springframework.web.context.ConfigurableWebApp licationContext]


This message is rather telling as ServerOsgiBundleXmlWebApplicationContext does implement the ConfigurableWebApplicationContext interface. For Spring to believe that it does not indicates that the class space being used by Spring is not consistent with the class space being used by your application, i.e. there are two different ConfigurableWebApplicationContext classes.

Looking at your MANIFEST.MF that you posted above, I can see that you're not importing Spring into your shared services WAR so, I presume, you've packaged it in WEB-INF/lib? This will mean that your application is using one copy of the Spring, and the dm Server is using another copy. Rather than packaging Spring in WEB-INF/lib, you should import it into your shared services WAR by updating your WAR's manifest. The easiest way to do this is to use the Import-Library manifest header. E.g.:



Import-Library: org.springframework.spring;version="[2.5.5,3.0.0)"


Hopefully making this change should resolve your problem.

You may be interesting in the formtags sample application (http://dist.springsource.com/release/SAMPL/formtags-1.4.0.RELEASE.zip), which provides an example of shared services WAR.

[cmoulliard]

You are right. I have packaged the Spring jarsin my WAR. I will remove them, add the import-library syntax in the MANIFEST file and re-deploy.

Many thanks for your verbose reply and the quality of your explanation.

KR,

Charles Moulliard

[cmoulliard]

Great, it works.

I have another error but this is not at all related to Spring DM.

By the way, if you are interested, you can have a look to my tutorial on Camel + Spring DM (first part published). I'm currently working on the second :

Hi,

I have a new error reported by the BundleDelegatingClassLoader. This looks strange for me because the class mentioned is part of Spring DM Serevr/Tomcat.

What is the reason of this error and how can I avoid it ?

Hi Charles,

My guess is that you're missing an import for org.apache.naming.java package in the manifest of your org.camel.example.reportincident.web bundle.

- Andy.

[cmoulliard]

You are right. I forget to add in the manifest file the following line : import-bundle: com.springsource.org.apache.catalina.

everything is ok now
