Hi Ami,
Following sinppet demonstrate the proper way to access an assertion in a
policy.
policy.getAlternatives() will return a iterator from which you can get a
list of assertions of an alternative.
Since your policy contains only one alternative it iterator will return only
one list. ( in othe words you can call iterator.next() only once). That
list will contain only a single assertion which you wanted to have access.
sample code:
String targetPolicy =
"<wsp:Policy xmlns:wsp=\"
http://schemas.xmlsoap.org/ws/2004/09/policy\"; xmlns:sp=\"
http://schemas.xmlsoap.org/ws/2005/07/securitypolicy\";>" +
"<wsp:ExactlyOne> " +
"<wsp:All>" +
"<sp:Basic256Rsa15 />" +
"</wsp:All>" +
"</wsp:ExactlyOne>" +
"</wsp:Policy>";
ByteArrayInputStream bais = new ByteArrayInputStream(
targetPolicy.getBytes());
Policy policy = PolicyEngine.getPolicy(bais);
Iterator alternatives = policy.getAlternatives();
List assertionList = (List) alternatives.next();
System.out.println(assertionList.get(0));
