Hi Tayeb, To compile your java program you need to tell javac where the classes that your code references are located. Specifically the classes that are not part of the standard Java library, such as Felix. If you run "javac -help" you can see all the parameters it takes. You'll find this line helpful:
-classpath <path> Specify where to find user class files and annotation processors So if you use this parameter to specify where the felix.jar is located, the "package <x> does not exist" errors should be resolved. You may need to do this for multiple jars depending on what classes your program references. hth, ken On Mon, May 14, 2012 at 5:10 AM, Tayeb Cherfouh <[email protected]>wrote: > Hi guys, > i am new at this world and i ve downloaded the felix framework, jdk and > sdk... well after that i ve started the apache tutorials with N°1: Apache > Felix Tutorial Example > 1<http://felix.apache.org/site/apache-felix-tutorial-example-1.html>: > A bundle that listens for OSGi service events. > it was great i ve learned much as i was writing the code and things, but > when i went to the cmd so i can compile it i just got lost! > first off what did they mean when they say to have felix.jar in the class > path? > second off this is what i get if i try to compile: > > c:\classes\tutorial\exp1>javac -d c:\classes *.java > Activator.java:7: error: package org.osgi.framework does not exist > import org.osgi.framework.BundleActivator; > ^ > Activator.java:8: error: package org.osgi.framework does not exist > import org.osgi.framework.BundleContext; > ^ > Activator.java:9: error: package org.osgi.framework does not exist > import org.osgi.framework.ServiceListener; > ^ > Activator.java:10: error: package org.osgi.framework does not exist > import org.osgi.framework.ServiceEvent; > ^ > Activator.java:16: error: cannot find symbol > public class Activator implements BundleActivator, ServiceListener > ^ > symbol: class BundleActivator > Activator.java:16: error: cannot find symbol > public class Activator implements BundleActivator, ServiceListener > ^ > symbol: class ServiceListener > Activator.java:24: error: cannot find symbol > public void start(BundleContext context){ > ^ > symbol: class BundleContext > location: class Activator > Activator.java:32: error: cannot find symbol > public void stop(BundleContext context){ > ^ > symbol: class BundleContext > location: class Activator > Activator.java:42: error: cannot find symbol > public void serviceChanged(ServiceEvent event){ > ^ > symbol: class ServiceEvent > location: class Activator > Activator.java:45: error: cannot find symbol > if(event.getType() == ServiceEvent.REGISTRED) > ^ > symbol: variable ServiceEvent > location: class Activator > Activator.java:49: error: cannot find symbol > else if (event.getType() == ServiceEvent.UNREGISTRED) > ^ > symbol: variable ServiceEvent > location: class Activator > Activator.java:53: error: cannot find symbol > else if (event.getType() == ServiceEvent.MODIFIED) > ^ > symbol: variable ServiceEvent > location: class Activator > 12 errors > > c:\classes\tutorial\exp1> > > it s obvious that i have an issue with the dependencies but how to fix that > ? > i dunno if this would help, but my tutorial java file is saved under > c:/classes/... while my felix-framework is under > d:/felix-framework-4.0.2... does this have anything to do with it? am i > supposed to have the tutorial under felix for instance or something? > > cheers, >
