Hi Nicolas,

Maybe to preserve the previous behaviour we can make this change dependent of 
the engine name?

So would be something like (putting "rest" in lowercase in the name being a 
convention)

        if (value.isEmpty() && name.contains("rest")) {
            Debug.logWarning("<parameter name=\"" + name + "\"> element value 
attribute is empty", module);
        }

Not sure it's really needed...

Hello,

I discovered a conflict with the management of service engine parameters and 
how I want to use them :)

I created a new engine to call rest service for a specific case with different parameters on the engine definition for a customer site. I have different OFBiz environments where my parameters value change :

        <engine name="rest-api-serveur-one" 
class="com.customersite.service.engine.RestClientApiEngine">
            <parameter name="authUrl" value="MyOaut2Server"/>...
            <parameter name="apiKey" value="04bdeada5093"/>
        </engine>

But on one environment, I need to put one parameter value to empty. The problem in the code base org.apache.ofbiz.service.config.model.Parameter.java:41 :

        if (value.isEmpty()) {
            throw new ServiceConfigException("<parameter> element value attribute is 
empty");
        }

So when ofbiz start, this instance failed because an empty parameters is considers as fatal for the server. I suggest to just inform that the parameter is empty instead of stop the server loading :

        if (value.isEmpty()) {
            Debug.logWarning("<parameter name=\"" + name + "\"> element value 
attribute is empty", module);
        }

Do you have an opinion ?

Nicolas
