javax.naming.NameNotFoundException - JNDI
Hi,
I just downloaded activeMQ 4.1.1 to learn something about message queues.
I started the message broker and used example code to run a JMS client.
I tried to follow the instructions in JNDI support to use JNDI names but had
no luck, I keep getting a javax.naming.NameNotFoundException error. have
included the error message below.
I created a jndi.properties file based on the example shown. have also
included the contents below.
I tried placing the jndi.properties file in my own jar file "jndi.jar"
which i refer to in the classpath.
I also placed the jndi.properties in the apache-activemq-4.1.1.jar . I am
not sure whether the jndi.properties file has
to be placed in a particular location in the jar. Tried a few things but
still I keep getting the error message.
i have also included a java code snippet.
would appreciate any help.
thanks
tony

Yes, the suggestion about the case sensititvity of the factory name was
correct.

Could it also be because you're trying to look up ConnectionFactory, whereas
you've defined an entry in your jndi.properties called connectionFactory? I
do believe the names are case-sensitive.

Its usually easiest to put the jndi.properties file in a directory
which is on the classpath; but it should be found if its in the root
directory of a jar

Note that this string "ConnectionFactory" is the JNDI name to use -
which you changed to "connectionFactory" in your editted
jndi.properties....

So it looks like you've overloaded what names you want the connection
factory to appear as. If you comment out this line (ie. use the
example jndi.properties file without changing it) your code would work
