Anne, I've done some more research. I created an even simpler WSDL because I think I'm going to have to submit an issue. The WSDL is listed at the bottom of this message. This is just a simple "echo" service that takes a string and returns a string.
If the client code uses the jars from nightly build from 8/30 it works fine. If the client code uses the jars from either last night or the night before it doesn't work (NullPointerException from the service). I used tcpmon to watch the requests being sent by the client and found that the only difference is the SOAPAction header. The older build (the one that works) sent the SOAPAction as urn:echoString. The latest nightly build sends the SOAPAction header as "". The WSDL specifies the soapaction="", so technically the newer build is setting the SOAPAction header correctly, but the Axis Servlet throws a null pointer exception for some reason. The older build incorrectly sets the SOAPAction to urn:echoString, which is incorrect based on the WSDL, but the Axis Servlet at least doesn't throw a NullPointerException. Here is the ironic part. I'm the person who filed the issue to get SOAPAction header set to "" when the WSDL specifies the SOAPAction as "". This was necessary because a non-java SOAP service I am using specifies a soapaction="". When my Axis2 client sent them any other SOAPAction, their service would reply back with an "Unknown operation". I'll go ahead and file another issue to get the Axis Servlet fixed to handle the SOAPAction header being "". -----Original Message----- From: Doolittle, Todd Sent: Thursday, September 07, 2006 2:06 PM To: '[email protected]' Subject: RE: Null pointer exception Anne, Thanks for the help! Well after doing a little troubleshooting it appears that something major was broken over the last couple of night in the nightly build. I created a much simpler WSDL by hand that defines an "Address book" service. The only operation is "lookup". You pass it the last name of the person you want to look up in the address book, and it returns their address book entry (name, address, etc). I then created a client and service using wsdl2java (from last night's nightly build). I just leave the service skeleton code as is. It will just throw an UnsupportedOperationException when it received a request. I deployed the service. The tomcat server is using axis.war from last night's build. If I run the client using last night's build jar files I get the NullPointerException returned from the service (see below for a stack trace). If I run the client with the 8/30/2006 nightly build's jar files I get the UnsupportedOperationException as expected. Considering how simple this service is, I'd say something major was broken between 08/30 and 09/05's build. I output the envelopes from the client and they look the same. So it's probably something being sent in an http header that is causing the problem. I haven't gotten the SOAP Monitor up and running yet, so I can't tell. Below is my WSDL if someone wants to verify it. <?xml version="1.0" encoding="UTF-8" standalone="no" ?> <wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"; name="AddressBook" targetNamespace="http://tempuri.org/"; xmlns:fjs="http://tempuri.org/"; xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";> <wsdl:types> <xsd:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/"; xmlns:s1="http://tempuri.org/";> <xsd:element name="personID"> <xsd:complexType> <xsd:sequence> <xsd:element name="lastName" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:element name="addressBookEntry"> <xsd:complexType> <xsd:sequence> <xsd:element name="lastName" type="xsd:string" /> <xsd:element name="firstName" type="xsd:string" /> <xsd:element name="address" type="xsd:string" /> <xsd:element name="city" type="xsd:string" /> <xsd:element name="state" type="xsd:string" /> <xsd:element name="zip" type="xsd:int" /> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:schema> </wsdl:types> <wsdl:message name="lookupIn"> <wsdl:part element="fjs:personID" name="parameters" /> </wsdl:message> <wsdl:message name="lookupOut"> <wsdl:part element="fjs:addressBookEntry" name="parameters" /> </wsdl:message> <wsdl:portType name="AddressBookPortType"> <wsdl:operation name="lookup"> <wsdl:input message="fjs:lookupIn" name="personID" /> <wsdl:output message="fjs:lookupOut" name="addressBookEntry" /> </wsdl:operation> </wsdl:portType> <wsdl:binding name="AddressBookBinding" type="fjs:AddressBookPortType"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http"; /> <wsdl:operation name="lookup"> <soap:operation soapAction="" style="document" /> <wsdl:input name="personID"> <soap:body use="literal" /> </wsdl:input> <wsdl:output name="addressBookEntry"> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="AddressBook"> <wsdl:port binding="fjs:AddressBookBinding" name="AddressBookPortType"> <soap:address location="http://localhost:8090/AddressBook/AddressBook"; /> </wsdl:port> </wsdl:service> </wsdl:definitions> Stack trace when using the 09/06 or 09/05 nightly build...
