Subject deploy a GBean - how ?
Date Mon, 19 Jan 2009 12:46:15 GMT

Hi,

I try to encapsulate my JNI calls in a GBean.

I read a lot of docs and articles, wrote my GBean along the sample in this
posting
http://www.nabble.com/POJO-caching-in-geronimo-td16986524s134.html

read this Wiki entry: http://cwiki.apache.org/GMOxDEV/gbeansarticle1.html
Unfortunately the entry does not tell how to install a GBean into the
server.

I guess, you use the deployer or console and deploy a jar together with a
plan, isn't it?

The Wiki entry links this sample from
http://apache.org/~hemapani/docs/gbeans-sample.zip
but it does not work with 2.1.3, console says:

java.lang.ClassNotFoundException:
org.apache.geronimo.upgrade.Upgrade1_0To1_1 in classloader
org.apache.geronimo.plugins/plugin-console-tomcat/2.1.3/car

org.apache.geronimo.kernel.config.MultiParentClassLoader.loadOptimizedClass(MultiParentClassLoader.java:437)

org.apache.geronimo.kernel.config.MultiParentClassLoader.loadClass(MultiParentClassLoader.java:279)
	java.lang.ClassLoader.loadClass(ClassLoader.java:597)

org.apache.geronimo.console.configmanager.DeploymentPortlet.processAction(DeploymentPortlet.java:189)
	org.apache.pluto.core.PortletServlet.dispatch(PortletServlet.java:218)
	org.apache.pluto.core.PortletServlet.doPost(PortletServlet.java:145)

Probably it does not like sample's plan's
<configuration
    xmlns="http://geronimo.apache.org/xml/ns/deployment"
    configId="test/plan2">
    

Then I tried

<?xml version="1.0" encoding="UTF-8"?>
<configuration
    xmlns:sys="http://geronimo.apache.org/xml/ns/deployment-1.2">
    configId="test/plan2">
    
    <gbean name="test:axis=gb1" class="my.JNIGBean">
    </gbean>
    
</configuration>

Now I get 

Deployment failed:
Cannot deploy the requested application module because no deployer is able
to handle it. This can happen if you have omitted the J2EE deployment
descriptor, disabled a deployer module, or if, for example, you are trying
to deploy an EJB module on a minimal Geronimo server that does not have EJB
support installed.

Then, how do I call a GBean method from a web app, is it still like cited in
the posting
http://www.nabble.com/POJO-caching-in-geronimo-td16986524s134.html ?

quoting:
<dependencies>
      <dependency>
        <groupId>com.w.core.geronimo.services</groupId>
        <artifactId>pojo-cache</artifactId>
        <version>1.0</version>
        <type>car</type>
      </dependency>
    </dependencies>
   
    ...
    </environment>  
    <gbean-ref
    xmlns:naming="http://geronimo.apache.org/xml/ns/naming-1.1">
    <ref-name>cache</ref-name>
    <ref-type>java.util.Map</ref-type>
    <pattern>
      <name>POJOCache</name>
    </pattern>
  </gbean-ref>
 
And get the cache in the following manner

  cache = (Map<String, Template>) new InitialContext()
          .lookup("java:comp/env/cache");

end quote

Thanks,
Juergen
