The spring xml file we are using like this:

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:osgi="http://www.springframework.org/schema/osgi"

xsi:schemaLocation="

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd

<osgi:reference id="datasource" interface="javax.sql.DataSource"/>

Any idea will be appreciated, thanks!

Best Regards.

Hi,

Does your karaf already install spring-dm feature? Especially Does the bundle spring-osgi-core get installed?
