You have two options:
1. You can modify your other bundles to wait until a log service is
available before continuing, thus they won't try to use it before
it appears.
2. You can install the log service into start level 1 and all your
other bundles into start level 2 (look in the spec for start
levels).
Approach 2 is simpler, but your bundles are more fragile and difficult
to reuse in other projects.

I guess that using a comination of both approaches is the best way to go.
I am planning to use the log service only if it is available. Otherwise the
jdk log will be available.
Is there a tutorial somewhere around the web that shows how to work with
startlevels.
How do i have to modify my startup class to work with startlevel:
<code>
Map<String, String> configMap = new HashMap<String, String>();
configMap.put(AutoProcessor.AUTO_DEPLOY_DIR_VALUE, "bundle");
configMap.put(AutoProcessor.AUTO_DEPLOY_ACTION_PROPERY,
AutoProcessor.AUTO_DEPLOY_UNINSTALL_VALUE + ',' +
AutoProcessor.AUTO_DEPLOY_INSTALL_VALUE + ',' +
AutoProcessor.AUTO_DEPLOY_START_VALUE + ',' +
AutoProcessor.AUTO_DEPLOY_UPDATE_VALUE);
The auto-deploy directory does not support start levels. If you want
start levels, you will have to use the Felix framework launcher
auto-start property or install the bundles programmatically.
-> richard
configMap.put(Constants.FRAMEWORK_STORAGE, "cache");
configMap.put(Constants.FRAMEWORK_STORAGE_CLEAN,
Constants.FRAMEWORK_STORAGE_CLEAN_ONFIRSTINIT);
configMap.put(Constants.FRAMEWORK_SYSTEMPACKAGES_EXTRA,
"javax.swing.plaf," +
"javax.swing.plaf.metal," +
"com.sun.java.swing.plaf.gtk," +
"com.sun.java.swing.plaf.motif," +
"com.sun.java.swing.plaf.nimbus," +
"com.sun.java.swing.plaf.windows");
try {
framework =
getFrameworkFactory().newFramework(configMap);
framework.init();
AutoProcessor.process(configMap,
framework.getBundleContext());
framework.start();
framework.waitForStop(0);
System.exit(0);
} catch (Exception ex) {
System.err.println("Could not create framework: " + ex);
System.exit(-1);
}
</code>
Greetings.
