Mina route on servicemix - Error executing command: java.lang.NullPointerException
Hi guys,
I've created a very simple camel route using the mina component. This
route actually uses a custom Codec and is packaged as osgi bundle.
Whenever I deploy it to servicemix (apache-servicemix-4.4.1-fuse-03-06)
the bundle is not getting the Active state but Installed. And of course
when I try to start it I'm getting a "Error executing command:
java.lang.NullPointerException" from the console, but nothing in the logs...
Can somebody help me make this work I can't figure out what's
happening... Is this a packaging issue? I guess it has something to do
with my codec loading, but I'm stuck here now.
Here is my XML route:
<?xml version="1.0" encoding="UTF-8"?>
<beans>
<bean id="myCodec" class="test.net.mina.codec.MyMinaCodec" />
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="mina:tcp://localhost:9000?sync=true&codec=#myCodec" />
<to uri="log:IncomingMsg" />
</route>
</camelContext>
</beans>
Here is my codecfactory (removed imports):
package test.net.mina.codec;
public class MyMinaCodec implements
ProtocolCodecFactory {
public ProtocolDecoder getDecoder(IoSession session) throws Exception {
return new MyMinaDecoder();
}
public ProtocolEncoder getEncoder(IoSession session) throws Exception {
return new ProtocolEncoder() {
public void encode(IoSession arg0, Object arg1,
ProtocolEncoderOutput arg2) throws Exception {
}
public void dispose(IoSession arg0) throws Exception {
}
};
}
}
And here is my decoder implementation (removed imports) :
package test.net.mina.codec;
public class MyMinaDecoder extends CumulativeProtocolDecoder {
public static final int MSG_HEADER_SIZE = 14;
@Override
protected boolean doDecode(IoSession session, IoBuffer in,
ProtocolDecoderOutput out) throws Exception {
// try to read the message header
if (in.remaining() >= MSG_HEADER_SIZE) {
out.write(readsUnsignedBytesToString(in, MSG_HEADER_SIZE));
return true;
} else {
// not enough data
return false;
}
}
private String readsUnsignedBytesToString(IoBuffer in, int length) {
char[] unsignedChars = new char[length];
for (int i = 0; i < length; i++) {
unsignedChars[i] = (char) in.getUnsigned();
}
return new String(unsignedChars);
}
}
And here is my pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Re: Mina route on servicemix - Error executing command:
java.lang.NullPointerException
Posted by Omar Atia <om...@its.ws>.
Try to start the bundle like this , check if there is missing in the imports ;
Start bundle-id
Check what error it raises .
Also when you start servimix you can check log
Log:display
Or under servicemix dirextory/data/log
Let me know results you get .
For error executing command , this is shell issue , wait till servicemix is up then do what I mentioned up.
Thanks,
Omar atia

Hi
First of all I suggest to make sure it works *outside* OSGi. eg create
a small unit test that tests that it works as expected.
Then when its working, you knows its an OSGi deployment issue, which
can be a beast by itself to tame.
