Hi there, friendly helpers!
I just started building web services with Apache Axis (configuration Tomcat
5, Axis 1.1, JSDK 1.4.1 on WinXP).
What I did:
- I put together a wsdl-file (relevant portions attached) with a complex
type "tps" consisting of a number of complex types ("tp")
- Using WSDL2Java I generated a client stub and server skeleton
(otsbindingimpl)
- I deployed my web service with the generated wsdd file
- yeap, Axis shows my web service in its list of deployed web services.
(http://127.0.0.1:8080/axis/servlet/AxisServlet: And now.. Some Services
*ots (wsdl))
- when I click on the wsdl link I get
Fault - makeTypeElement() was told to create a type "{urn:ots}>tps>tp", with
no containing element
- when I use my client to access the web service (service ots/method
gettps), I always get NULL as return value... (I'm not sure, if this is
connected to the makeTypeElement-Fault.
What I then did, following the good old trial&error-strategy:
- I added a <wsdlfile>ots.wsdl</wsdlfile> element to my wsdd file. I put the
wsdl file into the lib-directory containing my web service classes
(undeploy/ deploy with restart tomcat) Result: No change.
- I tried to access a standard web service (service Version, method
getVersion). Worked out fine. It returned the Axis Version Info.
- I googled around and read the mailing list... Only to find other people
with same problems, but no solutions.
Any ideas?
- Rick.

--- wsdl-file (relevant portion) ---
from the <types>-section:
I have a separate tp element and a tp element encapsulated in the tps
element. (- Axis didn't take a reference to external xsd-files. :( -) With
this specific problem only the encapsulated tp-type is relevant. the
separate one is for another method I have defined in the wsdl.
<xs:element name="tp">
<xs:complexType>
<xs:sequence>
<xs:element name="id" type="xs:string"/>
<xs:element name="predecessor_id" type="xs:string"/>
<xs:element name="hops" type="xs:integer"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="tps">
<xs:complexType>
<xs:sequence>
<xs:element name="tp" minOccurs="0" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="id"
type="xs:string"/>
<xs:element name="predecessor_id"
type="xs:string"/>
<xs:element name="hops"
type="xs:integer"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
the rest (standard):
<message name="gettps_IN">
<part name="maxhops" element="ots:maxhops"/>
</message>
<message name="gettps_OUT">
<part name="tps" element="ots:tps"/>
</message>
<portType...
<binding...
<service...

any information you are missing for some successful trouble shooting? I
would be happy to supply more.
