I need a Servlet to be started when the web container is starting
Hi All I have a problem to set up a framework application on Geronimo. I need a Servlet to be started when the web container is starting. As I previously did this configuration on Tomcat y try to add the Servlet definition on installDir\var\catalina\conf\web.xml and it loads the Servlet the problem is that the servlet has dependency classes and does not found them on runtime. I try to add the jar containing the classes to installDir\var\shared\lib and did not work. What is the right way to accomplish this? Is there a default application like in OAS or Tomcat? Do I have to add my own module to Geronimo (If so can you give me some directions?) The stack trace says that the class can not be found on Tomcat6/2.0.1/car do I have to add the dependence on that module for the dependent jars? (how can I do that?)

Re: I need a Servlet to be started when the web container is starting
Hi, Did you try write a simple geronimo-web.xml and deploy it along with your war file when you use sharedlib? Here's some information on geronimo-web.xml (geronimo specific web deployment plan) - http://cwiki.apache.org/GMOxDOC21/geronimo-webxml.html You can also try use the plan creator portlet (http://cwiki.apache.org/GMOxDOC21/plan-creator.html) to do that. In the geronimo-web.xml, you can specify the sharedlib as the depedency (I sent you the sample in the other reply). To deploy the war file at GERONIMO_HOME/bin dir, issue ./deploy.sh deploy file.war geronimo-web.xml HTH Lin On Mon, Oct 13, 2008 at 12:50 PM, Juan David [EMAIL PROTECTED] wrote: Hi All I have a problem to set up a framework application on Geronimo.

Hi David I think what I need is descrived for you “If you need some code to execute before your actual apps start you could write a gbean to execute the code and deploy it in a plugin that depends on the tomcat plugin. If your apps depend on this service plugin it is sure to get started before the apps.” I would just get the code out of the servlet and put on a gbean , what I would need is a example of the gbean implementation and deployment if there is one available.

would just get the code out of the servlet and put on a gbean , what
I would
need is a example of the gbean implementation and deployment if
there is one
available.
A simple example of a gbean is (in the geronimo 2.1 branch) at plugins/
clustering/geronimo-farm/src/main/java/org/apache/geronimo/farm/config/
BasicClusterInfo.java
You can view it at
https://svn.apache.org/repos/asf/geronimo/server/branches/2.1/plugins/clustering/geronimo-farm/src/main/java/org/apache/geronimo/farm/config/BasicClusterInfo.java
This one uses constructor dependency injection. The important points
to note are:
- you can use constructor or setter dependency injection
- dependencies can be simple objects (strings, numbers, or something
you provide a PropertyEditor for) via attributes or other gbeans via
references
- references can be single valued in which case they are required or
collection-valued in which case they are optional and gbeans that
satisfy the criteria are added as they start.
- you have to provide meatadata for the gbean as GBeanInfo, as shown
at the end of the class
- there are a few special attributes such as the plugin classloader
and the geronimo kernel
- if you need to do something on shutdown your gbean can implement the
GBeanLifecycle interface.
The plan using this gbean is
https://svn.apache.org/repos/asf/geronimo/server/branches/2.1/plugins/clustering/farming/src/main/plan/plan.xml
This particular gbean has this configuration:
gbean name=ClusterInfo
class=org.apache.geronimo.farm.config.BasicClusterInfo
attribute name=name${PlanClusterName}/attribute
reference name=NodeInfos/reference
/gbean
This particular attribute is overridden in a config.xml fragment and
eventually the value comes from a property in var/config/config-
substitutions.properties however you probably wont need such
customization features for your first gbean.
The reference is blank which means that any gbean implementing the
NodeInfo interface specified in the GBeanInfo for BasicClusterInfo
will be added to the NodeInfos collection.
hope this helps, please ask questions as needed
david jencks
Thank you very much

I can't keep track of how tomcat starts. There might be a default
application with a configuration under var/tomcat.

depends on
