Unable to access resources using initial context factory
Dear all,
In short: I'm having difficulties setting up an initial context factory to
acces resources defined in context.xml . The complete story is as follows:
I'm trying to let send messages from Adobe lcds to JMS. I'm running into
jndi issues (I think) however. It says:
INFO: [LCDS] [INFO] JMS consumer for JMS destination
'java:comp/env/jmz/topic/flex/simpletopic
' is being removed from the JMS adapter due to the following
error: Name TopicConnectionFactory
is not bound in this Context
I've seen in the Tomcat JNDI Datasource HOW-TO that I would normally get the
tomcat jndi context with 'Context ctx = new InitialContext();'. But the
configuration of the lcds jms adapter requires me to fill in a
inititalcontextfactory. In order to get the correct settings I've made an
adapter myself with the following code:
ctx = new InitialContext();
System.out.println("my env = " +
ctx.getEnvironment());
.....
factory =
(TopicConnectionFactory)ctx.lookup("java:comp/env/jms/flex/TopicConnectionFa
ctory");
It's output is:
my env =
{java.naming.factory.initial=org.apache.naming.java.javaURLContextFactory,
java.naming.provider.url=vm://localhost, topic.MyTopic=example.MyTopic,
java.naming.factory.url.pkgs=org.apache.naming,
queue.MyQueue=example.MyQueue}
With this context I'm able to connect to my JMS implementation (activemq),
so I tried to copy this environment to the JMS adapter configuration and got
the error message above. To figure out what's going on, I tried the
following in my self made adapter:
Context ctx;
InitialContextFactory initFac = new
javaURLContextFactory();
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, "vm://localhost");
// env.put(Context.PROVIDER_URL,
"tcp://localhost:61616");
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.naming.java.javaURLContextFactory");
env.put(Context.URL_PKG_PREFIXES,
"org.apache.naming");
// env.put(Context.URL_PKG_PREFIXES,
"java:org.apache.naming");
ctx = initFac.getInitialContext(env);
.....
factory =
(TopicConnectionFactory)ctx.lookup("java:comp/env/jms/flex/TopicConnectionFa
ctory");
But I was unable to retrieve the TopicConnectionFactory (I've also tried the
commented code with the same result). The error is the same as the error I
get from the adobe JMS adapter so I'm doing something wrong here. I'm also
puzzled about the topic.MyTopic=example.MyTopic and
queue.MyQueue=example.MyQueue in the context environment. I haven't
specified that. I'm afraid that there may be some other resource
specification somewhere. I've searched for files with those texts but
haven't found them.
My tomcat/conf/context.xml contains:
<Resource name="jms/flex/TopicConnectionFactory"
auth="Container" type="org.apache.activemq.ActiveMQConnectionFactory"
description="JMS Connection Factory"
factory="org.apache.activemq.jndi.JNDIReferenceFactory"
brokerURL="tcp://localhost:61616" brokerName="LocalActiveMQBroker"/>
<Resource name="jmz/topic/flex/simpletopic" auth="Container"
type="org.apache.activemq.command.ActiveMQTopic" description="my topic"
factory="org.apache.activemq.jndi.JNDIReferenceFactory"
physicalName="APP.STOCK.MARKETDATA"/>
my web.xml contains:
<resource-ref>
<description>JMS Connection Factory</description>
<res-ref-name>jms/flex/TopicConnectionFactory</res-ref-name>
<res-type>org.apache.activemq.ActiveMQConnectionFactory</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
<resource-ref>
<description>Simple Topic</description>
<res-ref-name>jmz/topic/flex/simpletopic</res-ref-name>
<res-type>org.apache.activemq.command.ActiveMQTopic</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
I hope that if I know how to solve this in code I will also be able to solve
it in the adobe lcds configuration. For completeness, my current
messaging-config.xml contains:
<destination id="chat-topic-jms">
<properties>
<jms>
<destination-type>Topic</destination-type>
<message-type>javax.jms.TextMessage</message-type>
<connection-factory>java:comp/env/jms/flex/TopicConnectionFactory
</connection-factory>
<destination-jndi-name>java:comp/env/jmz/topic/flex/simpletopic
</destination-jndi-name>
<destination-name>APP.STOCK.MARKETDATA
</destination-name>
<delivery-mode>NON_PERSISTENT</delivery-mode>
<message-priority>DEFAULT_PRIORITY</message-priority>
<acknowledge-mode>AUTO_ACKNOWLEDGE</acknowledge-mode>
<transacted-sessions>false</transacted-sessions>
<initial-context-environment>
<property>
<name>Context.PROVIDER_URL</name>
<value>vm://localhost</value>
</property>
<property>
<name>Context.INITIAL_CONTEXT_FACTORY</name>
<!--
<value>org.apache.activemq.jndi.ActiveMQInitialContextFactory</value> -->
<value>org.apache.naming.java.javaURLContextFactory</value>
</property>
<property>
<name>Context.URL_PKG_PREFIXES</name>
<value>org.apache.naming</value>
</property>
</initial-context-environment>
</jms>
</properties>
<channels>
<channel ref="my-rtmp"/>
<!-- <channel ref="samples-amf-polling"/> -->
</channels>
<adapter ref="jms"/>
</destination>
I hope anyone has an idea...
