Hi All,
I am trying to calculate time taken to load the bundles in Felix. I played
around with some profiler tool such JProfiler but didn't get any easy way
out.
I finally wrote a small program to calculate the time taken. It is
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

public class CalculateTimeTaken {

/**
 * @param args
 */
public static void main(String[] args) {
// Get the start time of the process
long start = System.currentTimeMillis();
System.out.println("Start: " + start);

Runtime rt = Runtime.getRuntime();
try {

String command1 = "java -jar
C:\\Users\\KK\\Desktop\\felix-1.4.1\\bin\\felix.jar";

Process pr = rt.exec("cmd /c " + command1);
InputStream is = pr.getErrorStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
System.out.println("ERROR STARTS");
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
System.out.println("ERROR END");
int exitval = pr.waitFor();
System.out.println("exit status is " + exitval);
} catch (Exception e) {

e.printStackTrace();
}

// Get the end time of the process
long end = System.currentTimeMillis();
System.out.println("End  : " + end);

long elapsedTime = end - start;

// Show how long it took to finish the process
System.out.println("The process took approximately: " + elapsedTime
+ " mili seconds");

}

}


However, this fails with following error

Start: 1235369156728
ERROR STARTS
Auto-properties install: org.osgi.framework.BundleException: Unable to cache
bundle: file:bundle/org.apache.felix.shell-1.0.2.jar

Auto-properties start: org.osgi.framework.BundleException: Unable to cache
bundle: file:bundle/org.apache.felix.bundlerepository-1.2.1.jar


After this, it hangs ...
  

Stuart has given a pretty good explanation in another mail...I was just 
going to add that it hasn't "hung", it is running fine, but no 
interactive shell was installed (because of the errors you mention), so 
there is no way to do anything. Felix is running fine, though. :-)

Any help on what the issue might be?


By the way, is there a better way to calculate the time taken to load
bundles ??

Thanks,
