Here is sample code of reading EPR from file and contructing object. The
code is from
http://viewcvs.globus.org/viewcvs.cgi/wsrf/java/core/source/src/org/globus/w
srf/client/BaseClient.java?revision=1.43&view=markup
in = new FileInputStream(line.getOptionValue("e"));
this.endpoint =
(EndpointReferenceType)ObjectDeserializer.deserialize(
new InputSource(in),
EndpointReferenceType.class);
You'll need to modify it to suit your scenario of multiple EPRs.
