this is all i seem to have as result!

Usage: javac<options> <source files>
use -help for a list of possible options
You need to do something like:
javac -classpath d:\felix-framework\bin\felix.jar -d c:\classes *.java
But as Neil points out, you might be better of starting from a Java
tutorial to understand what is going on there first before jumping into
OSGi development, since your difficulty arises from not understanding
how to develop with Java on the command line.

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

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

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,
