I got the PaxLogging config working. But the iPOJO isn't.
Here's some code:
package com.example;
import ...*...
@Component(name="LogClientExample", immediate=true)
public class LogClient implements Runnable {
@Requires
private LogService logService;
private boolean running;
@Property
private String logString;
@Override
public void run() {
logService.log( LogService.LOG_INFO, "LogClient run().");
while( running) {
logService.log( LogService.LOG_INFO, "LogClient
Running..." + logString);
try {
Thread.sleep( 10000);
} catch (InterruptedException e) {
logService.log( LogService.LOG_WARNING, "", e);
}
}
}
@Validate
public void start() {
logService.log( LogService.LOG_INFO, "LogClient start()");
running = true;
new Thread( this).start();
}
@Invalidate
public void stop() {
logService.log( LogService.LOG_INFO, "LogClient stop()");
running = false;
}
}
Then I've created a file called 'com.example.LogClientExample.cfg' (I tried
just com.example.LogClient.cfg as well) with one line:
logString=New Hello
The logs come out as "LogClient Running...null"
Unless I put this in the metadata.xml:
<ipojo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="org.apache.felix.ipojo
http://felix.apache.org/ipojo/schemas/CURRENT/core.xsd";
xmlns="org.apache.felix.ipojo">
<!-- declare your component types and instances here -->
<instance component="LogClientExample" name="LogClientExampleInstance">
<property name="logString" type="java.lang.String"
value="Hello" />
</instance>
</ipojo>
