hi i make my first steps with sts and osgi

i want to use a apache mina in my bundle but get

Code:
org.osgi.framework.BundleException: The bundle could not be resolved. Reason: Missing Constraint: Import-Package: org.apache.mina.core.buffer; version="0.0.0"
	at org.eclipse.osgi.framework.internal.core.AbstractBundle.getResolverError(AbstractBundle.java:1313)
	at org.eclipse.osgi.framework.internal.core.AbstractBundle.getResolutionFailureException(AbstractBundle.java:1297)

	at org.eclipse.osgi.framework.internal.core.FrameworkConsole.run(FrameworkConsole.java:224)
	at java.lang.Thread.run(Thread.java:619)
i use maven for project configuration and defined the dependency for mina.

Code:
<dependency>
	<groupId>org.apache.mina</groupId>
	<artifactId>com.springsource.org.apache.mina.core</artifactId>
	<version>2.0.0.RC1</version>
</dependency>
with spring bundlor the manifest for my bundle is created

Code:
Import-Package: org.apache.mina.core.buffer,
 org.apache.mina.core.service,
 org.apache.mina.core.session,
 org.apache.mina.filter.codec,
 org.apache.mina.filter.codec.demux,
 org.apache.mina.filter.logging,
 org.apache.mina.handler.demux,
 org.apache.mina.proxy.utils,
 org.apache.mina.transport.socket.nio,
 org.osgi.framework,
 org.springframework.core.style,
 org.springframework.util
so the dependency is in the manifest, too


i recognized that the apache mina bundle is missing in my OSGi Run Configuration and donīt know how to add this in to it. Clicking to "Add Required Bundles" doesnīt solve. But "Validate Bundles" also shows the missing bundle.

need help
