java.lang.NoClassDefFoundError for javax.security.auth* packages

Hi,

I am using Apache Karaf with JAAS login module. My application throws 
java.lang.NoClassDefFoundError exception. If I import that 
javax.security.auth* packages in my bundle this problem is resolved. As 
these packages are provided by JRE, do I need to import them? I am using 
Karaf 3.0.1.

As I use Maven + Tycho for development, javax.security.auth* packages 
are not available for import and this causes PDE to show errors in 
manifest file.

Regards,

Raj

Sorry, I realized that removing javax.security.auth.* will not auto 
export those packages.

The workaround to my problem is to add the javax.security.auth.* to 
org.osgi.framework.bootdelegation thought this is strongly discouraged [1]

Thanks JB. I think some thing has changes in the current version of 
Eclipse and it does not export these packages and they are not available 
for import in the PDE.

Is there a workaround? What happens if I remove the javax.security.auth* 
from system packages?

Regards,

Raj

Hi Raj,

even if the packages are provided by the JRE (and defined in 
etc/jre.properties), you have to import it in your bundle: it's what we 
name the system packages.
