How to generate classes from wsdl using Maven and wsimport? - maven

Question

When I attempt to run "mvn generate-sources" this is my output :
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I do not receive any errors but there are no java classes generated from the wsdl file.
Here is my pom.xml file that I'm running the plugin against :
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>gensourcesfromwsdl</groupId>
<artifactId>gensourcesfromwsdl</artifactId>
<version>0.0.1-SNAPSHOT</version>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<version>1.12</version>
<executions>
<execution>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<wsdlLocation>http://mysite/firstwsdl.asmx?wsdl</wsdlLocation>
<packageName>com</packageName>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
</project>
What am I doing wrong ? The package com exists in the project 'gensourcesfromwsdl' and the wsdl location is valid.
When I run wsimport via the command line : >wsimport -keep -verbose http://mysite/firstwsdl.asmx?wsdl the class is generated.

Answer 1

To generate classes from WSDL, all you need is build-helper-maven-plugin and jaxws-maven-plugin in your pom.xml
Make sure you have placed wsdl under folder src/main/resources/wsdl and corresponding schema in src/main/resources/schema, run command "mvn generate-sources" from Project root directory.
C:/Project root directory > mvn generate-sources
generated java classes can be located under folder
target/generated/src/main/java/com/raps/code/generate/ws.
pom.xml snippet
<plugin>
<groupId>org.codehaus.mojo</groupId>

Here is an example of how to generate classes from wsdl with jaxws maven plugin from a url or from a file location (from wsdl file location is commented).
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<build>
<plugins>
<!-- usage of jax-ws maven plugin-->
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<version>1.12</version>
<executions>
<execution>
<id>wsimport-from-jdk</id>
<goals>
<goal>wsimport</goal>
</goals>
</execution>
</executions>
<configuration>
<!-- using wsdl from an url -->
<wsdlUrls>
<wsdlUrl>
http://myWSDLurl?wsdl
</wsdlUrl>
</wsdlUrls>
<!-- or using wsdls file directory -->
<!-- <wsdlDirectory>src/wsdl</wsdlDirectory> -->
<!-- which wsdl file -->
<!-- <wsdlFiles> -->
<!-- <wsdlFile>myWSDL.wsdl</wsdlFile> -->
<!--</wsdlFiles> -->
<!-- Keep generated files -->
<keep>true</keep>
<!-- Package name -->
<packageName>com.organization.name</packageName>
<!-- generated source files destination-->
<sourceDestDir>target/generatedclasses</sourceDestDir>
</configuration>
</plugin>
</plugins>
</build>

Answer 3

Even though this is bit late response, may be helpful for someone. Look like you have used pluginManagement. If you use pluginManagement
, it will not pick the plug-in execution.
It should be under
<build>
<plugins>
<plugin>

Answer 4

Try to wrap wsdlLocation in wsdlUrls
<wsdlUrls>
<wsdlLocation>http://url</wsdlLocation>
</wsdlUrls>

Answer 5

I see some people prefer to generate sources into the target via jaxws-maven-plugin AND make this classes visible in source via build-helper-maven-plugin. As an argument for this structure
the version management system (svn/etc.) would always notice changed
sources
With git it is not true. So you can just configure jaxws-maven-plugin to put them into your sources, but not under the target folder. Next time you build your project, git will not mark these generated files as changed. Here is the simple solution with only one plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<version>2.6</version>
<dependencies>
<dependency>
<groupId>org.jvnet.jaxb2_commons</groupId>
<artifactId>jaxb2-fluent-api</artifactId>
<version>3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-tools</artifactId>
<version>2.3.0</version>
</dependency>
</dependencies>
<executions>
<execution>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<packageName>som.path.generated</packageName>
<xjcArgs>
<xjcArg>-Xfluent-api</xjcArg>
</xjcArgs>
<verbose>true</verbose>
<keep>true</keep> <!--used by default-->
<sourceDestDir>${project.build.sourceDirectory}</sourceDestDir>
<wsdlDirectory>src/main/resources/META-INF/wsdl</wsdlDirectory>
<wsdlLocation>META-INF/wsdl/soap.wsdl</wsdlLocation>
</configuration>
</execution>
</executions>
</plugin>
Additionally (just to note) in this example SOAP classes are generated with Fluent API, so you can create them like:
A a = new A()
.withField1(value1)
.withField2(value2);

The key here is keep option of wsimport. And it is configured using element in
About keep from the wsimport documentation :
-keep keep generated files

Answer 7

i was having the same issue while generating the classes from wsimport goal. Instead of using jaxws:wsimport goal in eclipse Maven Build i was using clean compile install that was not able to generate code from wsdl file. Thanks to above example.
Run jaxws:wsimport goal from Eclipse ide and it will work
