Am trying to use IBM UDDI registry to search and then
to publish my service using UDDI4J API. My first
problem is when i tried to connect to IBM UDDI registy
with following snippet of code, as am running behind
"proxy server" firewall i am not able to connect to
IBM site.
//here is code which i am using to connect to IBM URL
UDDIProxy proxy = new UDDIProxy();
proxy.setInquiryURL("http://www-3.ibm.com/services/uddi/
testregistry/inquiryapi");

then by reading some of the user groups i got some
clue to set "proxy" for Apache SOAP and am asking my
program to use "proxy" setting for Apache SOAP with
below code.
Properties prop = System.getProperties();
prop.put("http.proxyHost","myproxy.com");
prop.put("http.proxyPort","8080");
prop.put("http.proxyUserName","username");
prop.put("http.proxyPassword","password");

when i tried to run this program am getting following
exception(s).
Exception in thread "main"
java.lang.NullPointerException

at Search.main(Search.java:42)

my Search.java line 42 is: BusinessList bl =
proxy.find_business("V", null, 0);

and i believe due to failure of Apache SOAP transport
am getting this uddi4j exceptions.

Any help would be appreciated highly!!!
Thanks,
