JAX-WS error on WSDL file: “Error resolving component 's:schema'”

Question

The Error

I am using wsimport in a Java project to generate sources for three SOAP web services. The first two work fine: I use the JAX-WS Maven plugin to grab the

Answer 1

Had same issue fixed it with below command:

wsimport -b http://www.w3.org/2001/XMLSchema.xsd -b xsd.xjb service.wsdl

where xsd.xjb refers to :

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
          xmlns:xsd="http://www.w3.org/2001/XMLSchema"
          xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
          version="2.0">

  <globalBindings>
    <xjc:simple />
  </globalBindings>

  <bindings scd="~xsd:complexType">
    <class name="ComplexTypeType"/>
  </bindings>

  <bindings scd="~xsd:simpleType">
    <class name="SimpleTypeType"/>
  </bindings>

  <bindings scd="~xsd:group">

This seems to be working for me finally. I am using apache maven cfx plugin

    <plugin>
                <groupId>org.apache.cxf</groupId>
                <artifactId>cxf-codegen-plugin</artifactId>

                    </execution>
                </executions>
            </plugin>

along with these changes I had to create jaxp.properties file in ..java/jdk/jre/lib folder with following property

  -Djavax.xml.accessExternalDTD=all

For Nick's solution to work you may have to add these two jvm arguments to your pom.xml So when encountering those errors:

org.xml.sax.SAXParseException; systemId: http://www.w3.org/2001/XMLSchema.xsd; lineNumber: 67; columnNumber: 11; External DTD: Failed to read external DTD 'XMLSchema.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property.

[WARNING] schema_reference: Failed to read schema document 'xml.xsd', because 'http' access is not allowed due to restriction set by the accessExternalSchema property. line 91 of http://www.w3.org/2001/XMLSchema.xsd

Just add those to your pom.xml

-Djavax.xml.accessExternalDTD=all
-Djavax.xml.accessExternalSchema=all

<vmArgs>
    <vmArg>-Djavax.xml.accessExternalDTD=all</vmArg>
    <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
</vmArgs>

Answer 4

If you don't actually care about this particular bit of the model data you might be able to use a JAXB bindings file to tell JAXB to map the offending bits to properties whose type is a DOM Element rather than actually trying to data bind them into normal JAXB classes. The unofficial JAXB guide has a section on this technique.

Answer 5

I solved this by adapting Vivek Pandey's method to Maven, while updating to the jaxws-maven-plugin 2.2. I'll reiterate it here for posterity:

Summary

Put this XJB customization file (see below) in your default binding files directory, and set wsimport to bind it and http://www.w3.org/2001/XMLSchema.xsd .

XJB Customization

The contents of the aforementioned XML file, xsd.xjb, that should go in your default binding files directory, is as follows (credit goes to Kohsuke):

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
          xmlns:xsd="http://www.w3.org/2001/XMLSchema"
          xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
          version="2.0">

  <globalBindings>
    <xjc:simple />
  </globalBindings>

  <bindings scd="~xsd:complexType">
    <class name="ComplexTypeType"/>
  </bindings>

  <bindings scd="~xsd:simpleType">
    <class name="SimpleTypeType"/>
  </bindings>

  <bindings scd="~xsd:group">
    <class name="GroupType"/>
  </bindings>

  <bindings scd="~xsd:attributeGroup">
    <class name="AttributeGroupType"/>
  </bindings>

  <bindings scd="~xsd:element">
    <class name="ElementType"/>
  </bindings>

  <bindings scd="~xsd:attribute">
    <class name="attributeType"/>
  </bindings>
</bindings>
