How to avoid the need to specify the WSDL location in a CXF or JAX-WS generated webservice client

Question

When I generate a webservice client using wsdl2java from CXF  which generates something similar to wsimport   via maven  my services starts with codes like this    WebServiceClient name    StatusManagement                      wsdlLocation    c  some absolute path to a wsdl file wsdl                     targetNamespace    http   tempuri org     public class StatusManagement extends Service        public final static URL WSDL LOCATION      public final static QName SERVICE   new QName  http   tempuri org     StatusManagement        public final static QName WSHttpBindingIStatus   new QName  http   tempuri org     WSHttpBinding IStatus        static           URL url   null          try               url   new URL  c  some absolute path to a wsdl file wsdl              catch  MalformedURLException e                System err println  Can not initialize the default wsdl from c  some absolute path to a wsdl file wsdl                   e printStackTrace                      WSDL LOCATION   url          The hardcoded absolute path really sucks  The generated class won t work in any other computer other than mine   The first idea is to put the WSDL file  plus everything it imports  other WSDLs and XSDs  somewhere in a jar-file and classpath it  But we want to avoid this  Since all that thing was generated by CXF and JAXB based in the WSDLs and XSDs  we see no point in needing to know the WSDL at runtime   The wsdlLocation attribute is intended to override the WSDL location  at least this is what i readed somewhere   and it default value is     Since we are using maven  we tried to include  lt wsdlLocation gt  lt  wsdlLocation gt  inside the configuration of CXF to try to force the source generator to leave the wsdlLocation blank  However  this simply makes it ignore the XML tag because it is empty  We did a really ugly shameful hack  using  lt wsdlLocation gt       lt  wsdlLocation gt    This changes other places too    WebServiceClient name    StatusManagement                      wsdlLocation                              targetNamespace    http   tempuri org     public class StatusManagement extends Service        public final static URL WSDL LOCATION      public final static QName SERVICE   new QName  http   tempuri org     StatusManagement        public final static QName WSHttpBindingIStatus   new QName  http   tempuri org     WSHttpBinding IStatus        static           URL url   null          try               url   new URL                     catch  MalformedURLException e                System err println  Can not initialize the default wsdl from                         e printStackTrace                      WSDL LOCATION   url          So  my questions are    Does we really need a WSDL location even if all the classes were generated by CXF and JAXB  If yes  why  If we do not really need the WSDL location  what is the proper and clean way to make CXF not generate it and avoiding it entirely  What bad side effects we could get with that hack  We still can t test that to see what happens  so if someone could say in advance  it would be nice

Martin Devillers solution works fine  For completeness  providing the steps below    Put your wsdl to resource directory like   src main resource In pom file  add both wsdlDirectory and wsdlLocation don t miss   at the beginning of wsdlLocation   like below  While wsdlDirectory is used to generate code and wsdlLocation is used at runtime to create dynamic proxy    lt wsdlDirectory gt src main resources mydir lt  wsdlDirectory gt   lt wsdlLocation gt  mydir my wsdl lt  wsdlLocation gt   Then in your java code with no-arg constructor    MyPort myPort   new MyPortService   getMyPort     Here is the full code generation part in pom file  with fluent api in generated code    lt plugin gt   lt groupId gt org codehaus mojo lt  groupId gt   lt artifactId gt jaxws-maven-plugin lt  artifactId gt   lt version gt 2 5 lt  version gt    lt dependencies gt       lt dependency gt           lt groupId gt org jvnet jaxb2 commons lt  groupId gt           lt artifactId gt jaxb2-fluent-api lt  artifactId gt           lt version gt 3 0 lt  version gt       lt  dependency gt       lt dependency gt           lt groupId gt com sun xml ws lt  groupId gt           lt artifactId gt jaxws-tools lt  artifactId gt           lt version gt 2 3 0 lt  version gt       lt  dependency gt   lt  dependencies gt    lt executions gt       lt execution gt           lt id gt wsdl-to-java-generator lt  id gt           lt goals gt               lt goal gt wsimport lt  goal gt           lt  goals gt           lt configuration gt               lt xjcArgs gt                   lt xjcArg gt -Xfluent-api lt  xjcArg gt               lt  xjcArgs gt               lt keep gt true lt  keep gt               lt wsdlDirectory gt src main resources package lt  wsdlDirectory gt               lt wsdlLocation gt  package my wsdl lt  wsdlLocation gt               lt sourceDestDir gt   project build directory  generated-sources annotations jaxb lt  sourceDestDir gt               lt packageName gt full package here lt  packageName gt           lt  configuration gt       lt  execution gt   lt  executions gt

Is it possible that you can avoid using wsdl2java  You can straight away use CXF FrontEnd APIs to invoke your SOAP Webservice   The only catch is that you need to create your SEI and VOs on your client end  Here is a sample code    package com aranin weblog4j client   import com aranin weblog4j services BookShelfService  import com aranin weblog4j vo BookVO  import org apache cxf jaxws JaxWsProxyFactoryBean   public class DemoClient       public static void main String   args           String serviceUrl    http   localhost 8080 weblog4jdemo bookshelfservice           JaxWsProxyFactoryBean factory   new JaxWsProxyFactoryBean            factory setServiceClass BookShelfService class           factory setAddress serviceUrl           BookShelfService bookService    BookShelfService  factory create               insert book         BookVO bookVO   new BookVO            bookVO setAuthor  Issac Asimov            bookVO setBookName  Foundation and Earth             String result   bookService insertBook bookVO            System out println  result       result            bookVO   new BookVO            bookVO setAuthor  Issac Asimov            bookVO setBookName  Foundation and Empire             result   bookService insertBook bookVO            System out println  result       result            bookVO   new BookVO            bookVO setAuthor  Arthur C Clarke            bookVO setBookName  Rama Revealed             result   bookService insertBook bookVO            System out println  result       result              retrieve book          bookVO   bookService getBook  Foundation and Earth             System out println  book name       bookVO getBookName             System out println  book author       bookVO getAuthor                You can see the full tutorial here http   weblog4j com 2012 05 01 developing-soap-web-service-using-apache-cxf

1  In some cases  yes   If the WSDL contains things like Policies and such that direct the runtime behavior  then the WSDL may be required at runtime    Artifacts are not generated for policy related things and such     Also  in some obscure RPC Literal cases  not all the namespaces that are needed are output in the generated code  per spec    Thus  the wsdl would be needed for them   Obscure cases though   2  I thought something like  would work    What version of CXF    That sounds like a bug   You can try an empty string in there  just spaces    Not sure if that works or not    That said  in your code  you can use the constructor that takes the WSDL URL and just pass null    The wsdl wouldn t be used   3  Just the limitations above

Seriously  the top answer is not working for me  tried cxf version 2 4 1 and 3 0 10  and generate absolute path with wsdlLocation every times   My solution is to use the wsdl2java command in the apache-cxf-3 0 10 bin  with -wsdlLocation classpath wsdl QueryService wsdl   Detail       wsdl2java -encoding utf-8 -p com jeiao boss testQueryService -impl -wsdlLocation classpath wsdl testQueryService wsdl http   127 0 0 1 9999 platf testQueryService wsdl

We use   wsdlLocation    WEB-INF wsdl WSDL wsdl    In other words  use a path relative to the classpath   I believe the WSDL may be needed at runtime for validation of messages during marshal unmarshal

For those using org jvnet jax-ws-commons jaxws-maven-plugin to generate a client from WSDL at build-time    Place the WSDL somewhere in your src main resources Do not prefix the wsdlLocation with classpath  Do prefix the wsdlLocation with     Example    WSDL is stored in  src main resources foo bar wsdl Configure jaxws-maven-plugin with  lt wsdlDirectory gt   basedir  src main resources foo lt  wsdlDirectory gt  and  lt wsdlLocation gt  foo bar wsdl lt  wsdlLocation gt
