Programmatically use WsImport with JAXB plugins wi

Question

I am using WsImport to generate some Java sources from a remote WSDL file. Note that this is being from inside a regular Scala project i.e. it is not being done in a Maven or Ant build:

import com.sun.tools.ws.WsImport

def run(wsdlFile: File, destination: File, packageName: String = "generated"): Seq[File] = {        
  sys.props("javax.xml.accessExternalDTD") = "all"
  sys.props("javax.xml.accessExternalSchema") = "all"
  val xjcArgs = "" //TODO
  val args = s"-Xnocompile -XadditionalHeaders $xjcArgs -J-Djavax.xml.accessExternalDTD=all -b http://www.w3.org/2001/XMLSchema.xsd -p $packageName -s $destination $wsdlFile"
  WsImport.doMain(args.split(' '))
}

The above code works great and I use it to generate a Java WSDL client programatically from above Scala code.

But, now, I also want to use some WsImport plugins (such as this and this):

val xjcArgs = "-B-Xequals -B-XhashCode -B-Xvalue-constructor"

I am getting this error: no such JAXB option: -Xequals even though I added the following to my classpath:

"org.jvnet.jaxb2_commons" % "jaxb2-basics" % "1.11.1",
"org.jvnet.jaxb2_commons" % "jaxb2-value-constructor" % "3.0",

How do I force WsImport to use these plugins? Or do I use some other tool besides the WsImport (such as ANT) directly?

Trying with ANT

I am using com.sun.tools.ws.WsImport above but there is also another com.sun.tools.ws.ant.WsImport and I am not compeltely sure how to use it. I tried this:

val task = new com.sun.tools.ws.ant.WsImport2()
task.setPackage(packageName)
task.setWsdl(wsdlFile.getAbsolutePath)
task.setDestdir(destination.getAbsoluteFile)
task.setGenerateJWS(true)
task.setXadditionalHeaders(true)
task.setXnocompile(true)
task.setBinding("http://www.w3.org/2001/XMLSchema.xsd")
task.execute()

The above "almost works" but I can't figure out how to set binding in the ant task. wsimport takes in a -b http://www.w3.org/2001/XMLSchema.xsd but the ant task only accepts files as arguments :(

Answer 1

I am at the same deadlock as the author of the thread trying to tweak gradle's Java source code generation from wsdl.

And the reason for that is jaxb2-basics implements com.sun.tools.xjc.Plugin and @Optional in his answer refers to com.sun.tools.ws.WsImport. At the same time wsimport utility of "modern" Jdk8 rather implements com.sun.tools.internal.ws.WsImport and use com.sun.tools.internal.xjc.Plugin. So jaxb2-basics become kind of obsolete for using with wsimport of Jdk8.

The solution would be to use alternative library to provide WsImport in "old" namespace. E.g. com.sun.xml.ws:jaxws-tools:2.3.0. In Gradle it looks like:

configurations {
  jaxws
}

dependencies {
  jaxws 'org.jvnet.jaxb2_commons:jaxb2-basics:0.11.1'
  jaxws 'com.sun.xml.ws:jaxws-tools:2.3.0'

  compile 'org.jvnet.jaxb2_commons:jaxb2-basics-runtime:0.11.1'
}

wsdlServices.each { u ->
  task "ws${u.service}" (type: JavaExec) {
    classpath = configurations.jaxws

    workingDir = generatedDir
    main = 'com.sun.tools.ws.WsImport'
    args = ['-keep', '-Xnocompile', '-B-XtoString', '-B-Xequals', '-B-XhashCode', u.url]

    compileJava.dependsOn path // depends on current task
  }
}

and in command line this will be:

java -cp "lib/*" com.sun.tools.ws.WsImport -extension -keep -Xnocompile -B-XtoString 'http://www.webservicex.com/globalweather.asmx?WSDL'

where lib contains

commons-beanutils-1.9.2.jar
commons-collections-3.2.1.jar
commons-lang3-3.2.1.jar
FastInfoset-1.2.13.jar
gmbal-api-only-3.1.0-b001.jar

i.e. org.jvnet.jaxb2_commons:jaxb2-basics:0.11.1 and com.sun.xml.ws:jaxws-tools:2.3.0 with dependencies

Answer 2

Can you modify your val xjcArgs to include classpath there. e.g

val xjcArgs = "-cp _path_ofjaxb2-basics.jar:other_plugin_jar_with_path -B-Xequals -B-XhashCode -B-Xvalue-constructor" to make sure classpath is set on WSImport call?

Edit

Based on comment: here is my ant command that does. Basically you need all the supporting jars as well.

<project name="jaxws-stack" default="wsimport">
<property name="jaxws.home" location="D:/tmp/wsimport"/>
<path id="wsimport.classpath">
    <fileset dir="${basedir}/lib">
            <include name="*.jar"/>
        </fileset>
</path>

<taskdef name="wsimport" classname="com.sun.tools.ws.ant.WsImport" classpathref="wsimport.classpath"/>

<target name="wsimport">
    <wsimport keep="true" verbose="true" wsdl="mywsdlurl_path">
        <xjcarg value="-Xequals"/>
        <xjcarg value="-XhashCode"/>
        <xjcarg value="-Xvalue-constructor"/>
    </wsimport>
</target>

In my D:/tmp.wsimport I have following jars:

       233,859 commons-beanutils-1.9.2.jar
       315,805 commons-lang3-3.1.jar
       293,543 commons-lang3-3.1.jar.zip
        60,686 commons-logging-1.1.1.jar
        23,205 istack-commons-runtime-2.21.jar
         7,595 istack-commons-tools-1.1.jar
        25,446 istack-commons-tools-2.21.jar
       866,992 jaxb-impl-2.1.10.jar
     3,147,690 jaxb-xjc-2.1.11.jar
       141,087 jaxb2-basics-1.11.1.jar
       166,736 jaxb2-basics-runtime-1.11.1.jar
       141,604 jaxb2-basics-tools-1.11.1.jar
         5,756 jaxb2-value-constructor-3.0.jar
     1,284,131 jaxws-rt-2.1.4.jar
       510,892 jaxws-tools-2.1.4.jar
        33,739 stax-ex-1.7.7.jar
       130,161 streambuffer-0.9.jar

Just call Ant's default target and you will get proper java files.

Edit 2 to support command line/programmatic call.

.

Option 1:

Call just the WSImport.

"jdk_location\bin\java.exe"    -cp "lib\*" com.sun.tools.ws.WsImport -keep -verbose -B-Xequals -B-XhashCode -B-Xvalue-constructor  http://www.webservicex.com/globalweather.asmx?WSDL

Option 2

Call via custom class.

Java class:

package test;

import com.sun.tools.ws.WsImport;

public class Test
{
    public static void main(String args []) throws Throwable
    {
        WsImport.doMain(args); 
    }
}

Command prompt call

"jdk_location\bin\java.exe" -cp ".;lib\*" test.Test  -keep -verbose -B-Xequals -B-XhashCode -B-Xvalue-constructo
r  -Xnocompile http://www.webservicex.com/globalweather.asmx?WSDL

Option 2c

Again a custom java class/method which you can use in scala to use. Make sure you have the classpath properly set with the jars I listed.

package test;

import com.sun.tools.ws.WsImport;
public class MyWSImport {

    public static void main(String[] args) throws Throwable {

        String [] input = new String[] {"-keep",
                                "-verbose","-B-Xequals",
                                "-B-XhashCode",
                                "-B-Xvalue-constructor","-Xnocompile",
                                "http://www.webservicex.com/globalweather.asmx?WSDL"};
        WsImport.doMain(input); 

    }

    public void execute() throws Throwable
    {

        String [] input = new String[] {"-keep",
                                "-verbose","-B-Xequals",
                                "-B-XhashCode",
                                "-B-Xvalue-constructor","-Xnocompile",
                                "http://www.webservicex.com/globalweather.asmx?WSDL"};
        WsImport.doMain(input); 
    }
}
