What code are you using to construct your registry?

this:

/**
* Bootstrap the application using HiveMind regsitry.
*
* @param args String[]
*/
public static final void main(String[] args) {
// create an application main class using HiveMind factory
registry = RegistryBuilder.constructDefaultRegistry();
VTMain main = (VTMain) registry.getService(VTMain.class);
main.execute();
}

It works when run in my JBuilder environment, but using the maven build,
will not run it.

TIA,
John

You will get this if HiveMind is unable to find its own hivemodule.xml
files. Although I don't quite see why it would fail. Note that
HiveMind (per default) uses the context class loader to load the
hivemodule.xml files.

Sorry if I can't provide any better help.

It is strange, because as far as I know these files are in the same JAR as
the HM code, which is clearly executing.

This is not a webapp BTW.

I get the impression your context class loader is set to something
"strange". You could verify that by doing something like this before
you construct the registry:

Thread.currentThread().setContextClassLoader(RegistryBuilder.class.getClassLoader());

Although I don't know how you should resolve this issue...

I am attempting to initialise an instance of a class with one of two
sets of data, specified in a hivemodule.xml file, defined as
contributions attached to configuration points.

The code shows instantiating of the object. If the service point called
is 'testConfig.address' the code runs ok, but if I call the service
point 'testConfig.address2' which references the second contribution it
fails with error:

Error at file:...../META-INF/hivemodule.xml, line 41, column 72: Unable

java.lang.reflect.InvocationTargetException

doing wrong.

--Code

public static void main(String[] args) {
Registry registry = RegistryBuilder.constructDefaultRegistry();
Address address =
(Address)registry.getService("testConfig.address2", Address.class);
System.out.print(address.getAddress());

Shing,

Thankyou for your suggestion , however it would appear that adding id to
schema is illegal as I receive the message:

SEVERE: Error at file:...../testConfig/bin/META-INF/hivemodule.xml, line
5, column 28: Unknown attribute 'id' in element
module/configuration-point/schema.

However on checking the documentation at
'HiveMind1.1/docs/descriptor.html#configuration-point' it states that id
is required. This would seem to go against the examples that are shown
in the documentation of the use of <schema> which do not have an id
attribute.

What is correct? Is id valid/required as an id of schema or not?

Please ignore the last messsage on this thread. In looking at the
documentation again I see that if an id is specified in the
<configuration-point> element it is illegal
to have an id in the <schema> element also. Therefore Shing's suggestion
will be invalid, I think.

You can't reuse a schema that is defined inside
an configuration-point. Define it standalone and
it will accept the id attribute:

<schema id="AddressSchema">
<element name="datum">
<attribute name="key" required="true"/>
<attribute name="value" required="true"/>
<conversion class="test.config.Datum"/>
</element>
</schema>

<configuration-point id="Address" schema-id="AddressSchema" />
<configuration-point id="Address2" schema-id="AddressSchema" />

I use this peace of code to build registry:
-----------
Registry registry= null;
try{
RegistryBuilder registryBuilder= new RegistryBuilder();
ClassLoader classLoader=
Thread.currentThread().getContextClassLoader();
ClassResolver classResolver= new DefaultClassResolver(
classLoader );
ModuleDescriptorProvider moduleDescriptorProvider= new
XmlModuleDescriptorProvider( classResolver, "hivemodule.xml" ); //
perhaps the place which should solve your problem
registryBuilder.addModuleDescriptorProvider(
moduleDescriptorProvider );
registryBuilder.addDefaultModuleDescriptorProvider();
Locale locale= Locale.getDefault();
registry= registryBuilder.constructRegistry( locale );

log.debug( "registry builded" );
executeWithRegistry( registry ); // abstract method where
all my logic goes

}catch( Exception ex ){
log.error( ex );
return;
}finally{
if( registry != null ){
log.debug( "going to shutdown registry" );
try{
registry.cleanupThread();
registry.shutdown();

}catch( Exception ex ){
log.error( "failed to shutdown registry", ex );
}
}
}
