3.0.0 alpha, and seam tutorial problem

[jjfraney]

I don't know the root of the problem, may not be jboss tool, but its a place to start.

I run the tutorial at http://docs.jboss.com/seam/latest/reference/en-US/html/gettingstartedwithjbosstools.html.

I finish the 'add action' section. There are two failures at this point. I'm not sure what these mean. I'm not expecting these kinds of errors in a tutorial. The tutorial hasn't given enough information, I think, to figgure out how to proceed.


1) clicking the 'ping!' button in the web view causes a null pointer exception (like the injection of log and facesMessages did not happen). Seam gives me the error page.

Here is the relevant part of stack trace (I left off ejb transaction rollback stack traces, but if you want to see them, I'll post 'em)

org.domain.seamhello.session.PingBean.ping(PingBean.java:21)

org.jboss.ejb3.entity.TransactionScopedEntityManagerInterceptor.invoke(TransactionScopedEntityManagerInterceptor.java:54)

2) The testng unit test fails for the ping method. A little red x appears next to the test named: 'org.domain.seamhello.test.PingTest.init' and the following shows up in the 'Failure Exception' window:

org.jboss.deployers.client.spi.IncompleteDeploymentException: Summary of incomplete deployments (SEE PREVIOUS ERRORS FOR DETAILS):

[jjfraney]

So, I found that the post above describes two different problems, and I've solved one of them. I found this on the seam forum: http://seamframework.org/Community/SeamTestDoesNotWorks and set all build JDK and runtime JRE libraries to java 1.5.

Now both the web page and the testng fail with the same null pointer exception.

John

[maxandersen]

please show the null pointer exception stacktrace.

[jjfraney]

Thanks.

I'm posting two traces, one from the jboss server.log, the other from the testng stack trace window, because there is some difference between them (even though both show a null pointer at the access to the @Log injected variable).

This first one is from the jboss server.log (jboss 4.2.1 GA):

[maxandersen]

got any other error information in the server logs ?

[jjfraney]

oops. Sorry. Looks like I messed up on this one.

The 1.5 32-bit jdk I have been using on my ubuntu 64bit system has been running fine up until a recent upgrade of ubuntu. Now, with a 64-bit 1.5 jdk, seam runs without error.

Sorry for the alarm. Thanks for your time.
