unit test compiles but throws NoClassDefFound exception

[beel]

Hi,

I'm just starting with trails. Using http://docs.codehaus.org/display/TRAILS/Testing as a guide, I'm trying to test the mappings and eventually load my database with data from files.

        public void testCreate() {
                DomainObj o = new DomainObj();
                o.setName("some name");
                o = persistenceService.save(o);
// assertEquals(o.getName(), "some name");
// assertNotNull(o.getId());
        }

The method compiles but throws an exception at persistenceService.save(o).

 java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet

The website Trails has generated runs fine, so I'm missing something simple.

Thanks,

 -Bill

You are missing servlet-api from your test classpath.

Thanks!
I edited pom.xml and added

                <dependency>
                        <groupId>javax.servlet</groupId>
                        <artifactId>servlet-api</artifactId>
                        <version>2.4</version>
                        <scope>test</scope>
                </dependency>

Now i'm on to a new error; FileNotFoundException: hibernate.cfg.xml. It must be a classpath issue again.

Hi

It's not necessarily a classpath issue. When you compile the
application Trails creates  an hibernate.cfg.xml file on the fly (I'm
not very fan of this functionality) and this functionality is not
available for testing.
Try this: After compiling look for target/classes/hibernate.cfg.xml
(or target/generated-sources/resources/hibernate.cfg.xml) and copy it
to  src/test/resources/hibernate.cfg.xml
Eventually, you will need to maintain this file manually every time
you add or delete an @Entity.

Let us know if it works.

Saludos.
Alejandro.
