This is the wrong approach. The system property stuff is legacy from the MBean days. It's certainly the wrong api to be extending, we need to let it die. :-) The correct approach is should be to create your own ValueMetaData | <deployment xmlns="urn:jboss:bean-deployer:2.0" xmlns:ldap="urn:jboss:ldap:1.0"> | | <bean name="LDAPLookUp" ...> | <!-- ldap config here --> | </bean> | | <bean name="blah"> | <property name="x"><ldap:property bean="LDAPLookUp" key="ldapkeyhere" default="..."> | </deployment> | The ldap:property parses to an implementation of ValueMetaData, something similar to the inject value metadata (AbstractDependencyValueMetaData), except it gets the value from the LDAPLookUp bean. (untested code) | public Object getValue(TypeInfo info, ClassLoader cl) throws Throwable | { | ControllerState state = dependentState; | if (state == null) | state = ControllerState.INSTALLED; | Controller controller = context.getController(); | ControllerContext lookup = controller.getContext(getUnderlyingValue(), state); | | if (isLookupValid(lookup) == false) | throw new Error("Should not be here - dependency failed - " + this); | | if (lookup == null) | return null; | | Object ldap = lookup.getTarget(); | if (result instanceof LDAPLookup == false) | throw new IllegalStateException("Not an LDAPLookup: " + ldap); | LDAPLookup ldapLookup = (LDAPLookup) ldap; | Object result = ldapLookup.lookup(key); | if (result == null) | return defaultValue; | return result; | } | But it is not documented how to do this, the only close example is the javabean namespace but that just creates objects directly from the xml. There maybe a case for abstracting this such that a bean could implement a "ValueFactory" interface | public interface ValueFactory | { | Object getValue(String key); | } | and us including a generic piece of xml in our schema to enable its use | <property name="x"><value-factory bean="LDAPLookup" key="..." default="..."/></property> | Which would probably cover most simple use cases?
