Hi,
I am new in karaf and OSGI technologies. I have created a simple OSGI bundle
with Camel and Spring and deployed the same in Karaf 4.2.0. The bundle has
started successfully but I cant see the log which my came route is supposed
to print. My code is using logger and sysout both.
Here is the bean class.
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.util.Date;
/**
* @version $Revision: 640450 $
*/
public class MyTransform {
private static final transient Logger LOG =
LoggerFactory.getLogger(MyTransform.class);
private boolean verbose = true;
private String prefix = "MyTransform";
public Object transform(Object body) {
String answer = prefix + " set body: " + new Date();
if (verbose) {
System.out.println(">>>> " + answer);
}
LOG.info(">>>> " + answer);
return answer;
}
public boolean isVerbose() {
return verbose;
}
public void setVerbose(boolean verbose) {
this.verbose = verbose;
}
public String getPrefix() {
return prefix;
}
public void setPrefix(String prefix) {
this.prefix = prefix;
}
}
