编写有关WSO2 CEP的自定义经纪人

Question

I have a question about Custom Broker.

I tried Custom Broker using an example from this blog article.
I downloaded a sample template Custom Broker from " https://dl.dropbox.com/u/17922825/blog/cep-ext-broker.zip ", I put cep-broker-1.0-SNAPSHOT.jar in CEP_HOME/repository/components/lib .

Next, I put broker.xml in CEP_HOME/repository/conf . Following contents of broker.xml :

<brokerTypes xmlns="http://wso2.org/carbon/broker"><br>
   <brokerType class="org.test.cep.broker.TestBrokerTypeFactory"/><br>
</brokerTypes>

And, restart and login to the management console.

But, I accessed Configure -> Broker -> Add on management console, and each time I get the following error messages dumped into Monitor -> System Logs

Error during rendering

Also, I get the same error when I access Configure -> Broker -> List, Main -> CEP Buckets -> Add and List.

I use version 2.1.0 of WSO2 CEP.

If I need to explain more, I will add more information later.
I entreat you to help me.
