Programmatically use WsImport with JAXB plugins without Maven or ANT?

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

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'
