SDP support is disabled by default. To enable SDP support, set the com.sun.sdp.conf system property by providing the location of the configuration file. The following example starts an application using a configuration file named sdp.conf:
% java -Dcom.sun.sdp.conf=sdp.conf -Djava.net.preferIPv4Stack=true ExampleApplication
ExampleApplication refers to the client application that is attempting to connect to the IB adaptor.
Note that this example specifies another system property, java.net.preferIPv4Stack. See the
Issues section for more information about why this property is used.
