Substitution variables in gbean attribute value


Hi,
Is there a way to use substitution variables when defining gbeans in
geronimo-web.xml? For example, I would like to define a SharedLib for our
application with an APP_HOME variable that points to the actual location of
files on the user's filesystem:

  <gbean name="SharedLib"
class="org.apache.geronimo.system.sharedlib.SharedLib">
       <attribute name="libDirs">${APP_HOME}/lib</attribute>
        <attribute name="classesDirs">${APP_HOME}/conf</attribute>
        <reference name="ServerInfo">
            <name>ServerInfo</name>
        </reference>
  </gbean>

I've tried setting an APP_HOME environment variable as well as passing
APP_HOME as a Java system property. I even tried
org.apache.geronimo.config.substitution.APP_HOME but that seems to be
specific to config.xml.

Thanks,

Anil Chawla

Create a Geronimo plugin should be the best way to do it, or you might
extend the Sharelib gbean, so that you could do anything you like :-)

Right. To summarize, deploying as a geronimo plugin could simplify things to the point that a user would only need to modify a config-substitutions.properties property (or you provide a tool to do this or you allow the plugin deployment plan to be customized, prior to installation within the geronimo server.

If you are willing to distribute your app as a "predeployed" geronimo plugin rather than an app that must be deployed on each server, you can include this config.xml info in the plugin.  The easy way is to use a maven project and the car-maven-plugin to package your app as a plugin.  The geronimo build has lots and lots of examples of how to set up the config.xml bits and default values for config-substitutions.properties such as the plugins/tomcat/tomcat subproject.

For example, is there an easy way to append to the classpath of the server when running geronimo.sh? If so, we can just ask our users to set APP_HOME as an environment variable and provide a startup script that runs gernonimo.sh with the right parameters.

that won't work, sorry.

Re: Substitution variables in gbean attribute value

Ivan, thanks for the prompt response. Our intention is to provide our users
with a WAR/EAR file and perhaps a simple startup script that they can edit
to set the correct environment variables for their environment. It is good
to know that there is a work-around like this but it might be a little too
complicated for our users.

Is there any other option for configuring external folders in our classpath
without putting a fixed path in geronimo-web.xml? For example, is there an
easy way to append to the classpath of the server when running geronimo.sh?
If so, we can just ask our users to set APP_HOME as an environment variable
and provide a startup script that runs gernonimo.sh with the right
parameters.

Thanks,

Anil Chawla

You could NOT use the substitution directly in geronimo-web.xml, but you
might try a workaround solution below, it should work :-)

a. After deploying your application into the server, then stop the server.
b. Open the var/config/config.xml, and find the segment for your
application.
c. Let's take the SharedLib as an example, add a xml fragment like :
    <gbean name="SharedLib">
        <attribute name="libDirs">${APP_HOME}/lib</attribute>


<attribute name="classesDirs">${APP_HOME}/conf</attribute>


    </gbean>
d. add the APP_HOME and its real value in the
var/config/config-substitutions.properties
e. Start the server, now it should use the value configured in the
config-substitutions.properties.
