How can i run a JSR-180 application on an actual device when i get:

java.lang.ClassNotFoundException: com/sun/midp/io/j2me/sip/Protocol
at javax.microedition.io.Connector.openPrim(+211)
at javax.microedition.io.Connector.open(+15)
at javax.microedition.io.Connector.open(+6)
at javax.microedition.io.Connector.open(+5)
at examples.OriginatingINVITE.d(+22)
at examples.OriginatingINVITE.a(+9)
at examples.OriginatingINVITE.a(+4)
at examples.a.run(+7)

The com.sun.midp.io.j2me.sip package is missing. Appearently this package is substituted with com.nokia.phone.ri.sip in the sipa-midp emulator at runtime.

Could this be done using the property javax.microedition.io.Connector.protocolpath so it will run on an actual device? How can i set this property in the .jad?

Or maybe someone has another approach?

Regards,

Marcel
