class path issue

Hi all,

Our web application deploy on tomcat is planning to move to
geronimo-tomcat6-2.2.

In our application, we use castor-codegen-1.1 to generate the java class
from the schema file.
The generated class is using the method 
Unmarshaller.unmarshal(com/bnt/ui/preference/xml/UserPreference, reader)
from the castor-1.1.

The class file is packed in the application jar and is inside the
web-inf\lib folder so when trying to unmarshall, the path of the class
provided in the unmarshall method is giving exception as

While deploying in the tomcat, there is no issue. Can anybody throw some
light on this?


Thanks,

Hi Kevan,

With your suggestion to hide the castor, now it is working

<dep:hidden-classes>
      <dep:filter>org.exolab</dep:filter>
      <dep:filter>org.castor</dep:filter>
    </dep:hidden-classes>
  </dep:environment> 

Instead of putting all the dependencies jar from the web-inf/lib to
repository folder of geronimo, I just moved the xerces.jar in the endorsed
folder and put the below deployment plan

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-2.0.1"
         xmlns:sys="http://geronimo.apache.org/xml/ns/deployment-1.2">
    <sys:environment>
        <sys:moduleId>
            <sys:groupId>samples</sys:groupId>
            <sys:artifactId>bhm</sys:artifactId>
            <sys:version>5.2</sys:version>
            <sys:type>war</sys:type>
        </sys:moduleId>	
       <sys:hidden-classes>
          <sys:filter>org.exolab</sys:filter>
          <sys:filter>org.castor</sys:filter>
       </sys:hidden-classes> 		
    </sys:environment>
    <context-root>/bhm</context-root>
	<gbean name="MyAppSystemProperties"           
class="org.apache.geronimo.system.properties.SystemProperties">
    <attribute name="systemPathProperties">
         com.myApp.ConfigFile=var
    </attribute>
    <reference name="ServerInfo">
        <name>ServerInfo</name>
    </reference>
</gbean>
</web-app>


So, is there any further improvement which can be done.

Thanks,
Ranjan

Hi Kevan,

Thanks for your response, you are right, the castor-1.0.5 is used by the
org\apache\geronimo\configs\webservices-common.
Can we overcome the jar issue by putting the castor-1.1 in the
repository.org.codehaus.castor/castor/1.1 and declare in the artifact alias
as 
org.codehaus.castor/castor/1.0.5/jar=org.codehaus.castor/castor/1.1/jar 
and declared as dependency in my deployment plan  
             <sys:dependency>
                <sys:groupId>org.codehaus.castor</sys:groupId>
                <sys:artifactId>castor</sys:artifactId>
				<sys:version>1.1</sys:version>
                <sys:type>jar</sys:type>
            </sys:dependency>

Now after putting the above code, I didn't get the exception related to
unmarshall method, instead I got the error

The above mention jar jakarta-oro-2.0.5 is also put in the

artifact alias as 
org.apache.jakarta-oro/jakarta-oro//jar=org.apache.jakarta-oro/jakarta-oro/2.0.5/jar
and in the deployment plan as 
           <sys:dependency>
                <sys:groupId>org.apache.jakarta-oro</sys:groupId>
                <sys:artifactId>jakarta-oro</sys:artifactId>
				<sys:version>2.0.5</sys:version>
                <sys:type>jar</sys:type>
            </sys:dependency>

I am wondering why the application cannot read the class file
org.apache.oro.text.regex.Pattern from the jar jakarta-oro-2.0.5.

Thanks,
Ranjan

Hi Ranjan,
Geronimo includes castor 1.0.5. I'm not positive, but I think it will probably be in one of your parent classloaders. So, if you require castor 1.1, you'll want to hide castor from your application. A deployment plan like the following should do that:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-1.1" xmlns:dep="http://geronimo.apache.org/xml/ns/deployment-1.1" xmlns:naming="http://geronimo.apache.org/xml/ns/naming-1.1">
  <dep:environment>
    <dep:moduleId>
      <dep:groupId>org.mygroup</dep:groupId>
      <dep:artifactId>MyApp</dep:artifactId>

      <dep:type>car</dep:type>
    </dep:moduleId>

    <dep:hidden-classes>
      <dep:filter>org.exolab</dep:filter>
      <dep:filter>org.castor</dep:filter>
