How to fetch fileds of GenericValue from a client application

[Zoltan Vereczi]

Hi,

I'm new to Ofbiz...
I have a very simple client application based on the
org.ofbiz.service.rmi.ExampleRemoteClient, talking to a remote Offbiz instance.
I exported the userLogin service and the service call from the client app
returns successfully.
I get the userLogin object from the result map as a GenericValue fine.
Next I try to get some fields from the GenericValue which
fails with an Exception.
As I debugged the client side code I realized that getting a field from the
GenericValue involves GenericEntity and GenericDelegator from the included
Ofbiz jars and my call fails as it tries to create a new GenericDelegator with
the name "default" and tries to log this action with org.ofbiz.base.util.Debug.
I get a MissingResourceException: Can't find bundle for base name cache,
locale hu_HU.
I guess it's because I don't have a configured Ofbiz instance on the client
side, no configuration files, propertiy files there, only the jars,
and I guess I don't have a delegator at all there...
Can someone help me what do I have to do to fetch the fields of a GenericValue
returned by a service on the client side?
Do I have to setup my client app to use the remote delegator maybe?

my code:

// call the login service
Map result = dispatcher.runSync("userLogin", UtilMisc.toMap("login.username",
             username, "login.password", password));
GenericValue userLogin = (GenericValue) result.get("userLogin");
String userLoginId = userLogin.getString("userLoginId");


the Exception:

Thanks for your help in advance, Zoltan

When using certain objects, like the GenericValue object, from OFBiz  
there are a few resources you need. This error message says it can't  
find the cache.properties file, so you need to add that to you  
application classpath.

First of all thanks for the fast reply.

I started to add the missing resources...
First I added cache.properties, debug.properties. If I only include
cache.properties I get the following exception:

java.lang.IllegalStateException:
[GenericEntity.getDelegator] could not find delegator with name default

if I add debug.properties it starts to throw ClassNotFoundExceptions. I
continued to add the missing jars and files. I had to add a lot of stuff, jars
(avalon, xerces, oro, geronimo...), even the entityengine.xml and the
serviceengine.xml,
security.xml... xsd files, and some more ofbiz jars as well. Not a few, a lot...
Is this normal?
Right now I'm getting the following on the console. Did I add unnecessary files
or still missing something (looks like it needs the entity definitions too)?

Thanks, Zoltan

All things needed are documented in ExampleRemoteClient.java
(cache.properties, other propertie, jars etc).

However the problem was about how to access the fields of
a GenericValue object, i.e. how to 'get inside' a GenericValue.
It was obvious that we have the information available on the client
side (printing out the object showed all), just had problems
about accessing the fields.

Zoltan found out that on the remote client side using the get
method leads you to nowhere, because it would drag way too many ofbiz
things (works with local) to the client side. He also found that the proper
way of getting these is by using the getAllFields, getFields etc. methods
instead.
