Lightweight Instance Initialization

Rate this Message:
Is beta-1 supposed to have the lightweight instance initialization
feature implemented as described in http://jakarta.apache.org/hivemind/instance-initialization.html ? I'm asking because i want to use it but i get an error that indicates that the class name parse isn't being donne correctly. I've tried looking in the source files and couldn't find any code that would implement this feature. If it's not implemented, any predictions for when it will be ?

I just saw in the change log that this is supposed to be implemented
since alpha-2. What i'm trying to do is use this feature for a create-instance. So i have <create-instance class="com.whatever.MyBean,testProperty=hi"/> I always get the error: Unable to process attribute class (of element state-object/create-instance): Unable to convert type 'com.whatever.MyBean,testProperty=hi' to a Java class, either as is, or in package com.whatever. with the following stacktrace: org.apache.hivemind.impl.ModuleImpl.resolveType(ModuleImpl.java:197) org.apache.hivemind.schema.rules.ClassTranslator.translate(ClassTranslator.java:35) org.apache.hivemind.schema.rules.ReadAttributeRule.begin(ReadAttributeRule.java:77) org.apache.hivemind.parse.ConversionDescriptor.begin(ConversionDescriptor.java:141) org.apache.hivemind.impl.SchemaElement.fireBegin(SchemaElement.java:228) org.apache.hivemind.impl.SchemaProcessorImpl.processElement(SchemaProcessorImpl.java:255) org.apache.hivemind.impl.SchemaProcessorImpl.processNestedElements(SchemaProcessorImpl.java:277) org.apache.hivemind.impl.SchemaProcessorImpl.processElement(SchemaProcessorImpl.java:257) org.apache.hivemind.impl.SchemaProcessorImpl.processRootElement(SchemaProcessorImpl.java:235) org.apache.hivemind.impl.SchemaProcessorImpl.process(SchemaProcessorImpl.java:223) org.apache.hivemind.impl.ConfigurationPointImpl.processContributionElements(ConfigurationPointImpl.java:268) org.apache.hivemind.impl.ConfigurationPointImpl.constructMapElements(ConfigurationPointImpl.java:224) org.apache.hivemind.impl.ElementsInnerProxyMap.inner(ElementsInnerProxyMap.java:54) org.apache.hivemind.impl.ElementsInnerProxyMap.entrySet(ElementsInnerProxyMap.java:47) org.apache.hivemind.impl.ElementsProxyMap.entrySet(ElementsProxyMap.java:55) ....(more).....

I tried to use the primitive model (as also mentioned
in http://issues.apache.org/jira/browse/HIVEMIND-120) when creating a service with a Swing component implementation called org.example.Main Does anyone know a work-around that would allow dependency injection on the org.example.Main? Using ObjectProviders like... <service-point id="MainCntrl" interface="org.example.Controller"> <invoke-factory model="singleton"> <construct class="org.example.DefaultController" initialize-method="afterPropertiesSet" autowire-services="false" service-id-property="serviceId" > <set-object property="view" value="instance:org.example.Main"/> </construct> </invoke-factory> <interceptor service-id="hivemind.LoggingInterceptor"/> </service-point> ...does not help if you want org.example.Main to get a reference to yet another service point.

That should be working for you; please double check your classpath,
make sure you have the right version of the JARs. I just checked the code and it should absolutely work for <create-instance>.

I checked and i'm very sure i'm using hivemind-1.1-beta1 and
hivemind-lib-1.1-beta1. Can you point out where in the source is this feature implemented so that i can make sure that i have the correct version ?

Hi,
Has anyone reached a conclusion to this? I'm having the same issue using hivemind 1.1.1. It works fine if I don't specify the property, but as soon as I do I get the same error as Hugo. So I know the classpath is fine. I know I'm missing something, and I'd appreciate any help at all. Here is the code. My class: public class Monkey { private String limb; public Monkey() { } public void setLimb(String s) { this.limb = s; } public String getLimb() { return this.limb; } } hivemodule.xml create-instance node (works): <create-instance class="com.novantas.xml.Monkey"/> hivemodule.xml create-instance node (doesn't work): <create-instance class="com.novantas.xml.Monkey,limb=leg"/> I have even tried putting 'limb' as a constructor argument to no avail. Many Thanks Clive

Hello Clive,
If the problem cannot be solved I would suggest you take a look at HiveMind Utilities project: in the hiveutils module, there is the "ObjectBuilder" service that enables you to create (through configuration in hivemodule.xml) any POJO (no need for interface, no limit on kind of POJO). The only difference with HiveMind for POJO is that it does not allow you to set interceptors (I use it mainly for "small" POJOs in my GUIs).
