JNDI - Custom Factory
Hi,
I have a problem with NamingException : "Cannot create resource instance"
with code :
initCtx = new InitialContext(); }
envCtx = (Context) initCtx.lookup("java:comp/env");
System.out.println(envCtx.lookup("bean/MemoireFactory"));
||
====> NamingException : "Cannot create resource instance"
Have you an idea to correct this ?
Configuration :
---------------
web.xml :
<resource-env-ref>
<resource-env-ref-name>bean/MemoireFactory</resource-env-ref-name>
<resource-env-ref-type>pastel.jsp.HD_Exemple</resource-env-ref-type>
</resource-env-ref>
server.xml :
<context ....>
<Resource name="bean/MemoireFactory" auth="Container"
type="pastel.jsp.HD_Exemple"/>
<ResourceParams name="bean/MemoireFactory">
<parameter>
<name>factory</name>
<value>pastel.jsp.MemoireFactory></value>
</parameter>
</ResourceParams>
</Context>
MemoireFactory :
public class MemoireFactory implements ObjectFactory
{
public MemoireFactory() {System.out.println("
MemoireFactory.constructeur");}
public Object getObjectInstance(Object obj,Name name, Context nameCtx,
Hashtable environment)
throws NamingException
{
// Acquire an instance of our specified bean class
HD_Exemple bean = new HD_Exemple();
// Customize the bean properties from our attributes
Reference ref = (Reference) obj;
Enumeration addrs = ref.getAll();
while (addrs.hasMoreElements())
{
RefAddr addr = (RefAddr) addrs.nextElement();
String nom = addr.getType();
String value = (String) addr.getContent();
System.out.println("MemoireFactory "+nom+"="+value);
}
// Return the customized instance
return (bean);
}
}
I have read the Tomcat's HowTo about JNDI Resources.
The version of Tomcat is : 4.0.2.
Thanks for your help,
Elisabeth
