The way I read the 2.3.1 code (http://cvs.apache.org/viewcvs.cgi/xml-soap/java/src/org/apache/soap/uti l/net/HTTPUtils.java?rev=1.26&content-type=text/vnd.viewcvs-markup) is that the java.net.UnknownHostException will propagate out of buildSocket and be caught in post, which then throws the IllegalArgumentException. SOAPHTTPConnection#send will in turn catch that exception and throw a SOAPException chained back to the IAE.
Are you saying that the stack trace for the java.net.UnknownHostException is being printed from code other than your own? Or did you add that to get to the bottom of the problem, and you are complaining that by the time your code gets an exception, the actual root cause (the UHE) has been wiped away? If the latter is true, the best advice I have is to use a nightly build instead of 2.3.1, as the current code base does not throw and IAE from post. Instead, it throws a SOAPException that is chained to the UHE that caused the problem in the first place.
