Summary

0001852: Web Service schema generation neglects to add namespace to nested types

Description

Given a web service endpoint (GreekEndpoint) that has a method that returns a bean (AlphaBean) that in turn contains a bean (BetaBean), the schema produced by Resin 3.1.1 fails to put the nested bean in the proper namespace.

In a sample project, the generated Resin schema looks like so:

    <xsd:schema version="1.0" targetNamespace="http://ws.example.com/" [^] xmlns:m="http://ws.example.com/"> [^]
      <xsd:complexType name="alphaBean">
        <xsd:sequence>
          
          <xsd:element minOccurs="0" type="betaBean" name="beta"/>
          <xsd:element minOccurs="0" type="xsd:string" name="value"/>
        </xsd:sequence>
      </xsd:complexType>
      <xsd:complexType name="betaBean">
        <xsd:sequence>
          <xsd:element minOccurs="0" type="xsd:string" name="value"/>
        </xsd:sequence>
      </xsd:complexType>
      <xsd:element name="getAlphaBean" type="m:getAlphaBean"/>
      <xsd:complexType name="getAlphaBean"/>
      <xsd:element name="getAlphaBeanResponse" type="m:getAlphaBeanResponse"/>
      <xsd:complexType name="getAlphaBeanResponse">
        <xsd:sequence>
          <xsd:element name="return" type="m:alphaBean" minOccurs="0"/>
        </xsd:sequence>
      </xsd:complexType>
      <xsd:element name="getTime" type="m:getTime"/>
      <xsd:complexType name="getTime"/>
      <xsd:element name="getTimeResponse" type="m:getTimeResponse"/>
      <xsd:complexType name="getTimeResponse">
        <xsd:sequence>
          <xsd:element name="return" type="xsd:string" minOccurs="0"/>
        </xsd:sequence>
      </xsd:complexType>
    </xsd:schema>

However, the schema generated via wsgen:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema version="1.0" targetNamespace="http://ws.example.com/" [^] xmlns:tns="http://ws.example.com/" [^] xmlns:xs="http://www.w3.org/2001/XMLSchema"> [^]

  <xs:element name="getAlphaBean" type="tns:getAlphaBean"/>

  <xs:element name="getAlphaBeanResponse" type="tns:getAlphaBeanResponse"/>

  <xs:complexType name="getAlphaBean"/>

  <xs:complexType name="getAlphaBeanResponse">
    <xs:sequence>
      <xs:element name="return" type="tns:alphaBean" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="alphaBean">
    <xs:sequence>
      
      <xs:element name="beta" type="tns:betaBean" minOccurs="0"/>
      <xs:element name="value" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="betaBean">
    <xs:sequence>
      <xs:element name="value" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

The wsgen schema places the 'betaBean' type in the namespace of the service while Resin's generated schema leaves it to the default namespace of the containing WSDL, http://schemas.xmlsoap.org/wsdl/. [^]

This is reflected in clients that try to consume this WSDL.

SoapUI says: "Thu Jul 05 10:39:19 PDT 2007:WARN:Error: http://localhost:8080/greek/Greek?wsdl:0: [^] error: src-resolve.a: Could not find type 'betaBean@http://schemas.xmlsoap.org/wsdl/'. [^] Do you mean to refer to the type named betaBean@ href="http://ws.example.com/">http://ws.example.com/ [^] (in Greek_3Fwsdl)?"

Apache Axis 1.4 WSDL2Java says: "java.io.IOException: Type {http://schemas.xmlsoap.org/wsdl/}betaBean [^] is referenced but not defined."

Additional Information

I am using "Resin-3.1.1 (built Mon, 07 May 2007 09:32:40 PDT)" with JDK 1.6.0_01.

Here is a sample project that illustrates this issue (all files are likewise contained in attached zip file):

---
resin-web.xml
---
<web-app xmlns="http://caucho.com/ns/resin"> [^]
  <servlet-mapping url-pattern="/Greek"
                   servlet-class="com.example.ws.GreekEndpoint">
    <protocol type="soap" separate-schema="false" />
  </servlet-mapping>
</web-app>

---
GreekEndpoint.java
---
package com.example.ws;

import java.util.Date;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public class GreekEndpoint {

    public String getTime() {
        return new Date().toString();
    }

    @WebMethod
    public AlphaBean getAlphaBean() {
        BetaBean beta = new BetaBean();
        beta.setValue("beta");
        AlphaBean alpha = new AlphaBean();
        alpha.setValue("alpha");
        alpha.setBeta(beta);
        return alpha;
    }
}

---
AlphaBean.java
---
package com.example.ws;

public class AlphaBean {
    private String value;
    private BetaBean beta;

    public String getValue() {
        return this.value;
    }

    public void setValue(String value) {
        this.value = value;
    }

    public BetaBean getBeta() {
        return this.beta;
    }

    public void setBeta(BetaBean beta) {
        this.beta = beta;
    }

}

---
BetaBean.java
---
package com.example.ws;

public class BetaBean {
    private String value;

    public String getValue() {
        return this.value;
    }

    public void setValue(String value) {
        this.value = value;
    }

}

Notes
(0002101) djulian 07-05-07 11:15	I considered setting the severity of this issue to 'block' as it strongly argues against deploying our services with Resin's JAX-WS capabilities. However, I realize this development is still early so I'm unsure as to its "official" status. I learned the '<protocol type="soap" separate-schema="false" />' trick from issue 1838. The protocol tag and its attributes seem to be otherwise undocumented in the Resin documentation.
