How to properly access fields from GenericEntity

[John Martin]

I'm trying to integrate another system with ofBiz using a few RMI
calls.  Not being familiar with the ofBiz objects, I've gotten a
little stuck.

I'm calling the userLogin service and get back in the Map, a
[GenericEntity:UserLogin].  I cast the object back into a
GenericEntity and attempt to get various fields out but the system
bombs. Here's my code:

...
RemoteDispatcher rd.Naming.lookup(RMI_URL);
...
Map context = new HashMap();
context.put("login.username", username);
context.put("login.password", password);
Map result = rd.runSync("userLogin", context);
GenericEntity ge = (GenericEntity) result.get("userLogin");
// The object looks good in the debugger at this point, I can see the
key/value pairs

String userId =  ge.getString("userLoginId");
// This is where I try and access a field but it blows up.

What is the proper way to access the values from the GenericEntity?

Thanks,

John

The above line should be:

GenericValue ge = (GenericValue) result.get("userLogin");

The GenericEntity class models the entity definitions, while the
GenericValue class models the records in the entity.

U CAN CONVERT INTo MAP USING getallfields() method and then u can use.i need
some help on how to see GenericEntity in eclipse debug mode .i can't able to
do.i think ,I miss some classpath in eclipse

Hi Jacopo,

I ended up adding the entity source to my client app so I could walk
through and see the problem.  I've narrowed it down to the
GenericEntity is attempting to access a delegator (default) from the
pool but the pool is empty.

try {
                        delegator = new GenericDelegator(delegatorName);
                    } catch (GenericEntityException e) {
                        Debug.logError(e, "Error creating delegator", module);
                    }

sorry - Gmail can send emails before you want...

Being that this is a remote client attempting to access an object
passed over the wire, my thought is that something in the entity
classes was not properly initialized.  Any thoughts?

Thanks,

Hey Raj,

Thanks for the getAllFields() call, that worked.  It would be nice to
figure out what the delegator initialization issue was though.

The delegatorName variable is assigned in the web.xml
file for each webapp.  Out of the box all of the
delegatorName variables = "default" which is calling
the definition from
/framework/entity/config/entityengine.xml <deleagotor
name="default" ...>

So in short, call the same method but set String
delegatorName = (String) "default";
