JavaToWS 错误：java.lang.AbstractMethodError 从类生成 Web 服务

Question

I'm trying to generate a wsdl file from Java classes using Eclipse Oxigen (Right Click on class -> WebService -> Create Web Service) , Java 8u152 runtime and Tomcat 7.

With the following settings:

• Web Service type: Bottom up Java Bean Web Service Service
• Implementation: my concrete class
• Slider:Develop service
• Runtime: CXF 2.x
• SEI: my interface class

I have fed Eclipse with the CXF 3.2.2 jar (the same happens with 2.2.9 and 2.3.1).

I get the following error:

JavaToWS Error: java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V

    at org.apache.cxf.tools.java2ws.JavaToWS.main(JavaToWS.java:46)

And it does not generate anything but an unwanted cxf-beans.xml.

Am I missing something?

Answer 1

It's possible exists a problem with "xml-apis" or "xmlParserAPIs" on the classpath

you due to verify your version for it has the method javax.xml.parsers.DocumentBuilderFactory.setFeature(String ) .

For example, the first version with method in xml-apis is 1.4.01

Answer 2

In my case the problem was caused by xerces jar which was included in the classpath. I searched for it in Dependency Hierarchy of pom.xml and I have removed the artifact for xerces jar.

<exclusion>
       <groupId>batik</groupId>
       <artifactId>xerces</artifactId>
 </exclusion>
