IllegalArgumentException: key cannot be null - which key?

Trying to create a demo contract is the first service from the WSDL sample (using CXF 2.7.1 ):

<?xml version='1.0' encoding='UTF-8'?> <wsdl:definitions name="OrderProcessService" targetNamespace="http://order.demo/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://order.demo/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <wsdl:types> <xs:schema attributeFormDefault="unqualified" elementFormDefault="unqualified" targetNamespace="http://order.demo/" xmlns:tns="http://order.demo/" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="processOrder" type="tns:processOrder" /> <xs:element name="processOrderResponse" type="tns:processOrderResponse" /> <xs:complexType name="processOrder"> <xs:sequence> <xs:element minOccurs="0" name="arg0" type="tns:order" /> </xs:sequence> </xs:complexType> <xs:complexType name="order"> <xs:sequence> <xs:element minOccurs="0" name="customerID" type="xs:string" /> <xs:element minOccurs="0" name="itemID" type="xs:string" /> <xs:element name="price" type="xs:double" /> <xs:element name="qty" type="xs:int" /> </xs:sequence> </xs:complexType> <xs:complexType name="processOrderResponse"> <xs:sequence> <xs:element minOccurs="0" name="return" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:schema> </wsdl:types> <wsdl:message name="processOrderResponse"> <wsdl:part element="tns:processOrderResponse" name="parameters"> </wsdl:part> </wsdl:message> <wsdl:message name="processOrder"> <wsdl:part element="tns:processOrder" name="parameters"> </wsdl:part> </wsdl:message> <wsdl:portType name="OrderProcess"> <wsdl:operation name="processOrder"> <wsdl:input message="tns:processOrder" name="processOrder"> </wsdl:input> <wsdl:output message="tns:processOrderResponse" name="processOrderResponse"> </wsdl:output> </wsdl:operation> </wsdl:portType> <wsdl:binding name="OrderProcessServiceSoapBinding" type="tns:OrderProcess"> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="processOrder"> <soap:operation soapAction="" style="document" /> <wsdl:input name="processOrder"> <soap:body use="literal" /> </wsdl:input> <wsdl:output name="processOrderResponse"> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="OrderProcessService"> <wsdl:port binding="tns:OrderProcessServiceSoapBinding" name="OrderProcessPort"> <soap:address location="http://localhost:8080/OrderProcess" /> </wsdl:port> </wsdl:service> </wsdl:definitions>

I posted the following:

 wsdl2java -ant -impl -server -d src OrderProcess.wsdl

Source code generation is going well, but when I try to build a server using ant OrderProcessServer , I get the following exception:

 OrderProcessServer: [java] Starting Server [java] Exception in thread "main" java.lang.ExceptionInInitializerError [java] at org.eclipse.jetty.util.component.AbstractLifeCycle.<clinit>(AbstractLifeCycle.java:33) [java] at org.apache.cxf.transport.http_jetty.JettyHTTPDestination.activate(JettyHTTPDestination.java:178) [java] at org.apache.cxf.transport.AbstractObservable.setMessageObserver(AbstractObservable.java:48) [java] at org.apache.cxf.binding.AbstractBaseBindingFactory.addListener(AbstractBaseBindingFactory.java:95) [java] at org.apache.cxf.binding.soap.SoapBindingFactory.addListener(SoapBindingFactory.java:895) [java] at org.apache.cxf.endpoint.ServerImpl.start(ServerImpl.java:131) [java] at org.apache.cxf.jaxws.EndpointImpl.doPublish(EndpointImpl.java:360) [java] at org.apache.cxf.jaxws.EndpointImpl.publish(EndpointImpl.java:251) [java] at org.apache.cxf.jaxws.spi.ProviderImpl.createAndPublishEndpoint(ProviderImpl.java:152) [java] at javax.xml.ws.Endpoint.publish(Endpoint.java:57) [java] at demo.order.OrderProcess_OrderProcessPort_Server.<init>(OrderProcess_OrderProcessPort_Server.java:19) [java] at demo.order.OrderProcess_OrderProcessPort_Server.main(OrderProcess_OrderProcessPort_Server.java:23) [java] Caused by: java.lang.IllegalArgumentException: key can't be empty [java] at java.lang.System.checkKey(System.java:774) [java] at java.lang.System.getProperty(System.java:647) [java] at org.eclipse.jetty.util.log.Log$1.run(Log.java:122) [java] at java.security.AccessController.doPrivileged(Native Method) [java] at org.eclipse.jetty.util.log.Log.<clinit>(Log.java:85) [java] ... 12 more [java] Java Result: 1 BUILD SUCCESSFUL Total time: 2 seconds

My questions:

  • What key?
  • How to ensure this so that I don't get an exception?
  • Why is wsdl2java creating incomplete code? (i.e. not enough .wsdl file?)

UPDATE: The ANT build.xml file created by the wsdl2java command has these two seemingly corresponding lines:

 <sysproperty key="java.util.logging.config.file" value="${cxf.etc.dir}/logging.properties"/> <sysproperty key="log4j.configuration" value="file:///${cxf.etc.dir}/log4j.properties"/>
  • Are they key (no pun intended) for the problem?
  • If so, what values ​​should be placed there to fix this?
  • How do I tell wsdl2java to generate code that I don’t need to fix?

The Jetty Log implementation reads system properties as follows:

 Enumeration<String> systemKeyEnum = Enumeration<String>)System.getProperties().propertyNames(); while (systemKeyEnum.hasMoreElements()) { String key = systemKeyEnum.nextElement(); String val = System.getProperty(key); // ... (process key/values) }

For some reason, you managed to get a blank key: "" in the properties of your system. Therefore, check all the places where you programmatically set the system properties (System.setProperty) and your java command line for the -D options. If this does not help, try to print the properties of your system before this exception occurs, or run a jpda debugging session and place a breakpoint either in log line 122 and in System.checkKey ().

Empty keys come from the cxfrun macro in the generated ant script, build.xml.

Comment it this way and you should be fine:

 <arg value="@{param1}"/> <arg value="@{param2}"/> <arg value="@{param3}"/> <arg value="@{param4}"/> <arg value="@{param5}"/> <jvmarg value="${cxf.endorsed.flag}"/> <!-- Commented out to remove empty keys in system properties --> <!-- jvmarg value="@{jvmarg1}"/> <jvmarg value="@{jvmarg2}"/> <jvmarg value="@{jvmarg3}"/> <jvmarg value="@{jvmarg4}"/> <jvmarg value="@{jvmarg5}"/ -->
