Re: [equinox-dev] ClassNotFoundException with sun.misc package

Hi Srijith,

The only packages from rt.jar that are automatically available to you
are the ones beginning with "java.". All others, including javax.*,
org.w3c, etc must be imported using a normal Import-Package statement.

All of the standard rt.jar packages (such as javax.*) are exported by
the System Bundle, so your Import will resolve against that. However
the sun.misc package is non-standard so not exported by the System
Bundle.

The best way to resolve this problem is to NOT USE sun.misc, since
that will make your bundle run only on Sun JVMs! There are Base64
encoders available in other libraries, such as Apache Commons Codec.
If you really cannot avoid using the sun.misc package, then you can
add it to the org.osgi.framework.system.packages property, so the
System Bundle exports it.

Regards
Neil
