No declaration can be found for element 'osgi:reference'

Question

I am running on Apache ServiceMix 6.1.0.

I have the following dependencies in pom.xml of the foo project:

<dependencies>
    <dependency>
        <groupId>com.proj.bar</groupId>
        <artifactId>foo</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>3.2.14.RELEASE</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-parent</artifactId>
        <version>2.15.3</version>
        <type>pom</type>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.osgi</groupId>
        <artifactId>org.osgi.compendium</artifactId>
        <version>4.2.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-core</artifactId>
        <version>2.15.3</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

I have the following in my spring core-context.xml:

<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"

            <entry key="osgi.jndi.service.name" value="ConfigService" />
        </service-properties>
    </osgi:service>
</beans>

I have the following in my spring foo-context.xml

<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"

                filter="(osgi.jndi.service.name=ConfigService)"/>
</beans>

I am getting the following Exception:

I am completely at a loss of what i can do to fix this. It seems to be working fine in my core project, but i am not doing anything different. It seems like it doesn't recognize the osgi:reference tag, but the namespace definitions should be correct.

Does anyone know what might cause this?

Thnx in advance!

Answer 1

Your xsi:schemaLocation is missing a reference to osgi, it only has osgi-compendium.

You also need to add this:

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