About Question enthuware.oce-ejbd.v6.2.419 :

Post by PedroKowalski »

Howdy!

I was thinking about the last answer:
@Resource(lookup="jms/myTCF")
ConnectionFactory myTCF;
It is wrong because it doesn't use the java:global JNDI namespace but the relative value, right?
So if I use the "lookup" attribute JNDI location for @Resource it always have to be the global one?

Thanks in advance!

Cheers!

I think it is correct because the question says, "... specified it in your message producer's environment under the name "jms/myTCF"..." Therefore, java:comp/env/jms/myTCF and jms/myTCF both are valid.

So you think that the last one is also correct?

To be clear - I'm not telling that it should be :-)
I would just like to know why it is incorrect, as there is no explanation to this answer.

Thanks in advance!

Cheers!

No, there is no attribute named "lookup", it should be "name" as in @Resource(name="jms/myTCF") This is explained in option 3.

The J6EE version introduced "lookup" attibute to the @Resource annotation!, please check if the question/s should be altered.

You are right. The option is wrong because as per the API javadoc for lookup, "It can link to any compatible resource using the global JNDI names. "

For Option 3, the explaination of why it is wrong says:
"The right syntax for resource injection would be:
@Resource(name="jms/myTCF")
ConnectionFactory myTCF;"

But according to 6.2.420, the name does not need to be specified, as "name" is the default attributes.
viewtopic.php?f=4&t=801
So option 3 should also be correct.

Have you tried this? Resouce annotation doesn't compile without name attribute specified. So Option 3 should be
@Resource(name="jms/myTCF")
ConnectionFactory myTCF;

otherwise is not correct.

admin do you mind checking the last comment posted by Nuno Agostinho. because he is correct. in case of annotations if there is an attribute named value in the annotation defintion, then only can you skip writting the attribute name(if no other attributes have been specified) i.e MyAnnotation("helloworld).

i wonder why nuno hasnt been replied to since feb 24
