exporting services via spring configuration not working [message #1004153]

Folks,
I have a bundle ( a DAL ) where I have specified it as a service using the spring xml configuration.
When I deploy this, it gets resolved, and I can START it, making it active.

When I inspect it, I get that there are "No registered Services" from this, so when I try to USE it from another bundle, I get a NullPointerReference when trying to get the service.

How do I debug the registration of the service inside the Virgo container when the setup is via the spring xml config file?

Any help greatly appreciated...

Hi James.

You can inspect exported services in the Virgo Web Admin Console (localhost:8080/admin)

Or, you can enable telnet server, conect to it, and use the Equinox Console as well.

Enable it in : repository/ext/osgi.console.properties

And later

telnet localhost 2501 (default port)
> ss (to show status and bundle ids)

> services (objectClass="com.mypackage.MyService")

Will find an service that implements this interface.

Thanks -- it shows NO service that matches what I expect. It looks like the <osgi:service> items in the spring configuration are not causing this to be registered as a service...

Its is weird. Where is located the spring config in your project? Can you post all configuration?

OK, I have the spring config.xml in ...target/classes/META-INF/spring/config.xml
It has

....
    <bean id="myDriver" class="com.nnnnnn.msp.my_service.dao.MyDriverImpl">
	    <property name="documentTypeMapping" ref="documentTypeMapping" />
    </bean>
...    		     
    <osgi:service id="epiDaoOSGIService" ref="myDriver"
       interface="com.nnnnnn.msp.my_service.dao.MyDriver" auto-export="interfaces" >
    </osgi:service>

This tag means to have an ">" at the end of auto export.

<osgi:service id="epiDaoOSGIService" ref="myDriver"
       interface="com.nnnnnn.msp.my_service.dao.MyDriver" auto-export="interfaces" >
    </osgi:service>

Could try to change for that:

<osgi:service id="epiDaoOSGIService" ref="myDriver" interface="com.nnnnnn.msp.my_service.dao.MyDriver" />

As you are already declaring the implemented service interface, you do not need to declare the autoexport.

Do you use the osgi xml namespace?

This is a context config of a bundle here, that is working as expected:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>

James,

Would you mind posting MANIFEST.MF for this bundle? Do you see any errors in the logs? Is the bundle actually active?

Thanks
Dmitry

Sorry for this VERY late reply (I was pulled into another project for the past month and had no time for this).
HERE is the part of the config.xml:

<osgi:service ref="epiDriver" interface="com.moodys.msp.epi_service.dao.EpiDriver" />

HERE is the manifest for the bundle:

,org.springframework.jdbc.core;version="[3.0,4)",org.springframework.jd
bc.datasource;version="[3.0,4)"
Tool: Bnd-1.50.0

The bundles are ACTIVE, everything in the log appears to be fine here is the log from when I STARTED the bundle:

Bundle com.moodys.msp.epi_service-dao-jdbc-impl_1.0.0.SNAPSHOT, BundleEvent STARTED
Started bundle 'com.moodys.msp.epi_service-dao-jdbc-impl' version '1.0.0.SNAPSHOT'.

Nothing fails until I try to use the original service which uses this dao bundle.
