[Resteasy-developers] resteasy spring integration

[Cecil N. <cec...@gm...>]

Hello- A question on resteasy and spring...
I have used resteasy to connect to my database as a test case by hard/soft
coding in a properties file.  But to do it right I am trying to switch to a
connection pool.  So I put together the applicationContext.xml file for
Spring, etc.  It isn't working yet... I have tried various approaches, but
bottom line, it looks like spring is creating instances and so is resteasy.
So when resteasy tries to get my jdbc template instance, it is always null.

Based on the wiki article on this subject, I think the resteasy spring
version is supposed to inject *after* resteasy creates the instance.  I
suspect there's more config info that I am missing.  Hope someone can point
the way here.

Thanks

Here are some snippets in case it helps:

Are the beans being instantiated by Spring ok, but the request isn't 
being dispatched to the beans created by Spring?

I think you need turn off scanning, or just remove these lines

Turn off scanning by setting resteasy.scan to false.  I think removing 
that context-param declaration will work too.  Let me know how it goes.

If I turn of scanning or remove context-param, I get a 404

So I think the later is the case.  Here is console output.  Notice that no
JAX-RX resources are registered.  The STDOUT lines show the bean actions at
work.  The DAO var isn't null at that point.  Both variations are below.

Thanks for your help.

I'm baffled.  Here's a simple I used to test things:

http://resteasy.svn.sourceforge.net/viewvc/resteasy/trunk/jaxrs/jboss-integration-testing/spring-integration-test/


One thing I noted in your previous email.  Are you sure you have the 
correct class name in your bean definition?

     <bean id="dbquery3_dao" class="dbquery3_dao" >
         <property name="jdbcTemplate">
             <ref bean="gxoJdbcTemplate" />
         </property>
     </bean>


the id is the same as the "class" attribute.  Is this a typo? cut/paste 
error?

Took your example and modified it a bit to do some bean wiring.  The first
thing I noticed is that you use spring 2.5... I'm still at 2.0.  Do you know
if that is a strict dependency?

Assuming not... Not sure that the mail list can take attachments, but I'll
try that first.
- tweaked the LocatingResource.java code to add some get/set methods for
spring to use when configuring the bean.
- Added setup in applicationContext.xml and reverted to spring 2.0
- Set the scan to true (otherwise no jax-rs classes get registered
- Tweaked my standard build.xml to handle the directories in this case

Here is console output on deploy and a few lines after a test url.  You will
see that on startup the new variable in LocatingResouce is set to "OK" by
spring.  But on the GET url, it is null.

{Hoping that maybe this is all due to need for spring 2.5 and that it isn't
something more serious.  I'll take a stab using 2.5 next with this revised
example.}

Thanks for your help.

Yup... spring 2.5 did the trick.  I'll start on my database pilot app now
and use 2.5 there too.  Here's hoping!

Thanks!

I'll check the Spring api difference between 2.0 and 2.5.
