CXFServlet throws java.lang.NoSuchMethodError: org.codehaus.stax2.ri.EmptyIterator.getInstance()Lorg/codehaus/stax2/ri/EmptyIterator;

I'm using Java 11, Spring Boot 2.1.1 and Apache CXF 3.2.7 to expose a SOAP web service that imports an XSD schema. In the WSDL it shows like:

<wsdl:import location="http://localhost:9000/endpoint/ws?wsdl=WS_endpointSoapPort.wsdl" namespace="http://test.com"> </wsdl:import>

When I send a query it fails with the following stack:

2018-12-31 12:05:54,908 ERROR se.[Tomcat].[localhost].[/].[CXFServlet]: 175 - Servlet.service() for servlet [CXFServlet] in context with path [] threw exception [Servlet execution threw an exception] with root cause
java.lang.NoSuchMethodError: org.codehaus.stax2.ri.EmptyIterator.getInstance()Lorg/codehaus/stax2/ri/EmptyIterator;

Any thoughts?

I had a conflict on the org.codehaus.woodstox:stax2-api which was included in version 3.1.4 within org.apache.cxf:cxf-core and in version 4.1 within com.sun.xml.ws:rt. I solved the conflict by removing the library using Maven excludes:

        <exclusions>
            <exclusion>
                <groupId>org.codehaus.woodstox</groupId>
                <artifactId>stax2-api</artifactId><!-- 4.1 conflicts with 3.1.4 from apache cxf-spring-boot-starter-jaxws-->
            </exclusion>
        </exclusions>

After research in deeply, I found the following JIRA that mentions a problem with Stax2 version. BTW the ticket said that it resolves with the version that I'm using.

In the end, I fixed upgrading to woodstox-core-5.2.0. In fact, the library mentions a similar problem that was solved in that version. Details here.

I run into the same problem and upgrading to CXF 3.2.7 or later fixed the issue for me.

The key is likely in your mvn:dependency-tree output. In my case:

[INFO]    \- org.apache.cxf:cxf-rt-ws-security:jar:3.3.6:compile
[INFO]       +- org.apache.cxf:cxf-core:jar:3.3.6:compile
[INFO]       |  \- com.fasterxml.woodstox:woodstox-core:jar:5.3.0:compile (version managed from 5.0.3)
[INFO]       |     \- org.codehaus.woodstox:stax2-api:jar:4.2:compile
[INFO]       \- org.apache.wss4j:wss4j-policy:jar:2.2.5:compile

[INFO]                \- (org.codehaus.woodstox:stax2-api:jar:3.1.4:compile - omitted for conflict with 4.2)

org.apache.cxf:cxf-rt-ws-security:jar:3.3.6 leads to both version 3.1.4 and version 4.2 of stax2-api because of the very much outdated woodstox-core-asl dependency (from 2014). I will have to see if I can get rid of this, because it leads to the NoSuchMethodFoundError described above.

I had the same problem with some dependencies in Maven that used the stax2-api with different versions.

Maven compiler uses only one version of stax2-api (in my case it was the newest), so I tried to include versions 3.1.4 and 4.2.1 (that were required by other jars) using the runtime scope

Here is a snipped of the pom.xml

<dependency>
  <groupId>org.codehaus.woodstox</groupId>
  <artifactId>stax2-api</artifactId>
  <version>4.2.1</version>
  <scope>runtime</scope>
</dependency>
     
<dependency>
  <groupId>org.codehaus.woodstox</groupId>
  <artifactId>stax2-api</artifactId>
  <version>3.1.4</version>
  <scope>runtime</scope>
</dependency>

REMARKS: In my case it works when executing a class as a java application, but does not work when executing in a web application environment (Tomcat)!
