Hi James, finally it worked , but I haven't tested completely , but it seems it will
be okey :))
inside my factory class firstly I used
"MessageResourcesFactory.createFactory().createResources(config)" code fragment
to create file based MessageResource object of Struts ,
but it didn't worked correctly,
actualy it caused infinite loop in my factory class, I think
MessageResourcesFactory.createFactory()
returns same same instanse of my factory class, again and again calling same method on
same instance,,
I dont know exatly why , insted of
"MessageResourcesFactory.createFactory().createResources(config)"
I decided to use MessageResourcesConfig to get factory class, this code segment copied
from
initMesssageResources method of ActionServlet, it seem it works !!!!!!
Craig if you read this lines , is this way okey , are there any better way to create
struts messageResources object ???
another problem is how can I access message properties from my factory class, only
config parameter
is accessible , I want to use a message property to decide which kind of
MessageResource will be created !!!
to do this I am currently using config parameter,
*********************MY FACTORY CLASS *******************************
*********************MY FACTORY CLASS *******************************
*********************MY FACTORY CLASS *******************************
public class TebMessageResourcesFactory extends MessageResourcesFactory
{
public MessageResources createResources(String config) {
if (config == null || "Database".equalsIgnoreCase(config) ||
"VeriTabani".equalsIgnoreCase(config) )
// return own MessageResources object that reads messages from DATABASE
return new TebMessageResources(this, config, this.returnNull);
else {
// return struts MessageResources object that reads messages from FILE
SYSTEM
MessageResourcesConfig messageResConfig = new MessageResourcesConfig();
String factory = messageResConfig.getFactory();
MessageResourcesFactory.setFactoryClass(factory);
MessageResourcesFactory factoryObject =
MessageResourcesFactory.createFactory();
return factoryObject.createResources(config);
}
}
*********************END OF MY FACTORY CLASS *******************************
*********************END OF MY FACTORY CLASS *******************************
*********************END OF MY FACTORY CLASS *******************************
Looks good to me.
