[Design the new POJO MicroContainer] - Re: Microcontainer + Guice
by alesj
I've also added a way to do injection the other way around: from Guice into MC.
| AbstractBeanMetaData guicePlugin = new AbstractBeanMetaData("GuicePlugin", GuiceKernelRegistryEntryPlugin.class.getName());
| AbstractConstructorMetaData constructor = new AbstractConstructorMetaData();
| AbstractArrayMetaData arrayMetaData = new AbstractArrayMetaData();
| final Singleton singleton = new Singleton();
| Module module = new AbstractModule()
| {
| protected void configure()
| {
| bind(Singleton.class).toInstance(singleton);
| }
| };
| arrayMetaData.add(new AbstractValueMetaData(module));
| constructor.setParameters(Collections.singletonList((ParameterMetaData)new AbstractParameterMetaData(arrayMetaData)));
| guicePlugin.setConstructor(constructor);
| controller.install(guicePlugin);
|
| BeanMetaData holderBean = new AbstractBeanMetaData("holder", SingletonHolder.class.getName());
| controller.install(holderBean);
|
| ControllerContext holderContext = controller.getInstalledContext("holder");
| assertNotNull(holderContext);
| SingletonHolder holder = (SingletonHolder)holderContext.getTarget();
| assertNotNull(holder);
| assertEquals(singleton, holder.getSingleton());
|
|
The detail is in GuiceKernelRegistryEntryPlugin, which acts as a middle man between MC registry and Guice Injector instance.
| public class GuiceKernelRegistryEntryPlugin implements KernelRegistryPlugin
| {
| private Injector injector;
|
| public GuiceKernelRegistryEntryPlugin(Module... modules)
| {
| injector = Guice.createInjector(modules);
| }
|
| public void destroy()
| {
| injector = null;
| }
|
| public KernelRegistryEntry getEntry(Object name)
| {
| KernelRegistryEntry entry = null;
| try
| {
| if (name instanceof Class<?>)
| {
| Class<?> clazz = (Class<?>)name;
| entry = new AbstractKernelRegistryEntry(name, injector.getInstance(clazz));
| }
| else if (name instanceof Key)
| {
| Key<?> key = (Key<?>)name;
| entry = new AbstractKernelRegistryEntry(name, injector.getInstance(key));
| }
| }
| catch (Exception ignored)
| {
| }
| return entry;
| }
| }
|
MC documentation has already been updated with this new Guice-int module.

[Design of JBoss jBPM] - [GPD 3.1.0.SP1] NPE when opening process
by laurenzo
Hi,
I am trying to open the loan broker process provided with the mule project examples.
http://mule.codehaus.org/display/MULE/Loan+Broker+Example
GPD fails to open with NPE stack trace provided below. This was on version 3.1.0.CR1. I thought the fix of GPD-148 http://jira.jboss.com/jira/browse/GPD-148 would help but this issue is still present in 3.1.0.SP1 as well.
I would create a JIRA issue but can't seem to get access to the "new issue" feature. Let me know how to proceed if required.
Thanks
L.
