the ShrinkWrap and the NoClassDefFoundError

[chaiyilin]

hi guys,

i am a ShrinkWrap novice and just want to try the simplest example for novice ShrinkWrap (not with Arquillian), so the method:

    public static void main(String[] args) {

        JavaArchive javaArchive = ShrinkWrap.create(JavaArchive.class,

                "test.jar");

        javaArchive = javaArchive.addClasses(WordItem.class, WordItemDAO.class);

        javaArchive = javaArchive.addAsManifestResource("persistence.xml",

                ArchivePaths.create("persistence.xml"));

        System.out.println(javaArchive.toString());

    }

the class got complied but the execution immediately stop at first line: JavaArchive javaArchive = ShrinkWrap.create(JavaArchive.class,"test.jar");

and the exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/shrinkwrap/api/spec/JavaArchive

    at org.cyl.english.ffl.Entities.WordItemTest.main(WordItemTest.java:25)

what wrong with the code?

Do you have Shrinkwrap jars in the classpath of the application?

[chaiyilin]

of course. i am in eclipse and m2eclipse. otherwise this code will not get compiled.

I meant the runtime classpath of the application and not the compile time classpath. This exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/shrinkwrap/api/spec/JavaArchive

    at org.cyl.english.ffl.Entities.WordItemTest.main(WordItemTest.java:25)

Caused by: java.lang.ClassNotFoundException: org.jboss.shrinkwrap.api.spec.JavaArchive

indicates that the Shrinkwrap jar(s) weren't found in the runtime classpath.

haha, thanks jaikiran. you enlighten me. because i am using maven, i forgot put the arquillian to compile scope.  now it works. thanks again, dear jaikiran

[jaikiran]

You're welcome!

[alrubinger]

Arquillian in compile scope? Thought you weren't using Arquillian?

What you really want is to have shrinkwrap-api in compile scope, shrinkwrap-impl-base in "provided" or "test" scope (hence available to the runtime).

S,

thanks, andrew. just want to try the shrinkwrap api. not in production. thanks dear.
