Wrong method signature called depending on the name of the operation with JWS
-----------------------------------------------------------------------------
Key: AXIS-2211
URL: http://issues.apache.org/jira/browse/AXIS-2211
Project: Apache Axis
Type: Bug
Versions: 1.2.1
Environment: Windows Xp, Java 1.5.0_04, Tomcat 5.5.9, Axis 1.2.1
Reporter: Andrea Matsunaga
I have a JWS service with two methods with the same name but different
signatures (one has String and the other an array of string). This service was
working properly on Axis 1.1 (on Linux). Now, I'm trying to port it to Axis
1.2.1 (on Windows) and though the client is trying to access the operation with
a String, the operation with an array of string signature is being called by
Axis. Using the SOAPMonitor, it is possible to see that the client is sending a
proper SOAP message indicating a string (and not an array of string), but the
message returned is with an array of string. Adding some logs to my service, it
was verified that the wrong operation was invoked. The odd aspect of this is
that just by changing the name of the operation the expected behavior can be
"recovered". The only difference that I could notice is that the generated WSDL
shows the response/request messages in a different order, but this should not
be influencing wich operation is invoked. When the operation is named
"translate", the service misbehaves, while when the exact same service has its
operations renamed to "echoString", everything works fine.
Here is the service that misbehaves (i.e., when the client tries to access the
first method with String, Axis actually invokes the second with an array of
strings):
public class Echo {
public String translate(String lang, String text) {
return "Echo> " + text;
}
public String[] translate(String lang, String[] words) {
if (null != words) {
for (int i = 0; i < words.length; i++) {
words[i] = "Echo[" + i + "]> " + words[i];
}
}
return words;
}
}
Here is the service that works as expected (i.e., when the client tries to
access the first method with String, Axis invokes the first with a string; note
that only the operation name changed):
public class Echo {
public String echoString(String lang, String text) {
return "Echo> " + text;
}
public String[] echoString(String lang, String[] words) {
if (null != words) {
for (int i = 0; i < words.length; i++) {
words[i] = "Echo[" + i + "]> " + words[i];
}
}
return words;
}
}
