I don't think there are any spaces in any of the names involved. (I put
a few underscores in the changed names below.) I can see exactly where
the exception is ocurring - it's in HTTPSender.readFromSocket(), where
it detects the 302 status, closes the socket, clears the status code,
and sends it off to invoke() where it tries to construct a new URL based
on the 'location' field. Unfortunately, I seem to be getting an
incomplete spec for a URL in 'location' - it's missing the protocol and
the hostname.
(Emphasis here on the fact that I can talk with my own services just fine.)
Would there be anything else I have to do if they are trying to send me
back a url rather than plain text or xml?

Hi Rick-
most DNS servers wont do lookups on DNS CNAMEs for ServerName With Spaces
but rather CNAMEs without spaces such as
private static String URL =
"http://127.0.0.1:8080/axis2/services/AddressBookService";;
Call.java throws MalformedURLException when the EPR (URL) is malformed

Hi Martin,
Thanks. I added the following to my own code while configuring the call:
call.setProperty(MessageContext.HTTP_TRANSPORT_VERSION,
HTTPConstants.HEADER_PROTOCOL_V11);
Hashtable chunkedTable = new Hashtable();
chunkedTable.put(HTTPConstants.HEADER_TRANSFER_ENCODING,
HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED);
call.setProperty(HTTPConstants.REQUEST_HEADERS, chunkedTable);
Now I get similar results, but with one additional go-round. In
HTTPSender.readFromSocket, the first iteration gives me a 100
(continue), then when I do so, I get the 302 again, then the
MalformedURLException.
I should probably mention that this is Axis 1.4, Java 1.5 (OS X)

Hi Rick-
1st make sure you are enabling HTTP 1.1 protocol and chunkedEncoding
transfer-encoding as in this example from /conf/axis2.xml
<transportSender name="http"
class="org.apache.axis2.transport.http.CommonsHTTPTransportSender">
<parameter name="PROTOCOL">HTTP/1.1</parameter>
<parameter name="Transfer-Encoding">chunked</parameter>
<!-- If following is set to 'true', optional action part of the
Content-Type will not be added to the SOAP 1.2 messages -->
<!-- <parameter name="OmitSOAP12Action">true</parameter> -->
</transportSender>

Subject: HTML Status Code 302 And Exception When Contacting IIS Service
Greetings,
I'm new to this area of programming, so please bear with me if this is
something so simple a 5-year-old should be able to deal with. (In the
following code I've changed some names for the sake of confidentiality,
so the URLs will not actually work.)
I've written a very simple Axis client in Java, to contact a service on
a remote IIS machine. I'm passing a String and expecting an
acknowledgment back. I have written my own test service, running in
Tomcat on my own server, and it works fine. When trying to connect to
the IIS machine, my client chokes with various errors depending on the
spellings/misspellings of the endpoint URL. Most common is
MalformedURLException: no protocol. My code:
public void contact() {
try {
Service service = new Service();
Call call = (Call) service.createCall();
URL url = new
URL("http://remote_machine.us:80/product_name/login/Connect.aspx";);
call.setTargetEndpointAddress(url);
call.setOperationName(new QName("Connect.aspx",
"service_name"));
SOAPEnvelope se = new SOAPEnvelope();
Object[] paramValue = new Object[] { "hello from Rick" };
RPCElement rpce = new RPCElement("http://remote_machine.us";,
service_name, paramValue);
se.addBodyElement(rpce);
Object returnValue = (Object) call.invoke(se);
System.out.println(returnValue.toString);
}
catch (ServiceException se) {
se.printStackTrace();
}
catch (MalformedURLException mue) {
mue.printStackTrace();
}
catch (RemoteException re) {
re.printStackTrace();
}
}
I have walked through the Axis source code trying to find a reason for
this. Call.invoke() sends me to HTTPSender.invoke():
targetURL = new URL(msgContext.getStrProp(MessageContext.TRANS_URL));
// targetURL is OK
String host = targetURL.getHost();
// host is the domain name minus the protocol, ie: remote_machine.us, I
presume this is OK
int port = targetURL.getPort();
// port is 80
// Send the SOAP request to the server
InputStream inp = writeToSocket(socketHolder, msgContext, targetURL,
otherHeaders, host, port, msgContext.getTimeout(),
useFullURL);
// Read the response back from the server
Hashtable headers = new Hashtable();
inp = readHeadersFromSocket(socketHolder, msgContext, inp, headers);
// the returned headers look plausible to me: {connection= close, date=
Thu, 29 Nov 2007 15:06:32 GMT, server= Microsoft-IIS/6.0,
content-length= 199, x-powered-by= ASP.NET, cache-control= private,
x-aspnet-version= 1.1.4322, microsoftofficewebserver= 5.0_Pub,
location=
/product_name/login/Connect.aspx?ReturnUrl=%2fproduct_name%2flogin%2fConnect
aspx,
content-type= text/html; charset=utf-8}
readFromSocket(socketHolder, msgContext, inp, headers);
The fun begins in HTTPSender.readFromSocket:
Integer rc =
(Integer)msgContext.getProperty(HTTPConstants.MC_HTTP_STATUS_CODE);
// rc = 302 (moved/redirect)
If rc == 302, readFromSocket() closes the connection and tries to
construct a new URL (and a new connection):
// Temporary Redirect (HTTP: 302/307)
// close old connection
inp.close();
socketHolder.getSocket().close();
// remove former result and set new target url
msgContext.removeProperty(HTTPConstants.MC_HTTP_STATUS_CODE);
msgContext.setProperty(MessageContext.TRANS_URL, location);
// next try
invoke(msgContext);
In HTTPSender.invoke():
try {
BooleanHolder useFullURL = new BooleanHolder(false);
StringBuffer otherHeaders = new StringBuffer();
// The following line raises a MalformedURLException, since the
string it is getting from msgContext is not a complete specification
for
a URL:
"/product_name/login/Connect.aspx?ReturnUrl=%2fproduct_name%2flogin%2fConnec
t.aspx":
targetURL = new
URL(msgContext.getStrProp(MessageContext.TRANS_URL));
.
.
}
When I point a browser at the original URL I am redirected to this
page:
"http://remote_machine.us:80/product_name/login/LoginDisplay.aspx/product_na
me/login/Connect.aspx?ReturnUrl=%2fproduct_name%2flogin%2fConnect.aspx"
Questions:
* Is there any way for me to handle this effectively in code? What am I
doing wrong?
* This is supposed to end up as an automated process; does it make
sense
for it to blindly follow a redirect without knowing where it's going?
Seems risky to me.
* Is the 302 a meaningful error code, or could it be masking something
else?
Any suggestions most welcome!
Rick Strong
