Spring, Apache CXF and Embedded Jetty - web-services

I'm trying create a web service capable server using Apache CXF, Spring and an embedded Jetty server. When I run my project the server seems to initialize correctly, however when I navigate to http://localhost:8080/SomeService expecting to see the service WSDL, instead I get the following exception:
SEVERE: /SomeService
java.lang.NullPointerException

I should mention that I'm using the Maven one-jar plugin, although I doubt that makes any difference to this problem.

Servlet filter invoke not on default port [duplicate]

I'm running embedded jetty inside of a spring ioc container. The spring ioc contains also an embedded hsqldb which makes the whole configuration a nice and complete web application development environment (on a single JVM). Now I'm trying to add apache CXF to this environment to make the jetty host not only servlets but also web services.
Unfortunately I'm getting NullPointerException when attempting to access http://127.0.0.1:8080/cxf/* (servlets and static content are served ok). Any idea what's wrong?

I've found out that the above configuration was wrong:
I did not use any WebApplicationContext with has to be initialized prior to the CXFServlet. The simple solution is to use the non-spring version of CXFServlet - it does not require any ApplicationContext (I don't want to create a separate ApplicationContext for the Web Services since I need to have shared DataSource between them) but it has too be initialized (Web Services must be published in the code).
After solving the Context issue I've found out that jetty 6.1 does not initialize the servlet context in proper way, everything works fine after updating to 7.x.
After writing custom WebApplicationContext I was able to use the main/root ApplicationContext as the WebApplicationContext allowing me to use the spring version of CXFServlet with about 6 lines of glue code.

You are autowiring addNumberEndpoint by name so Spring will look for calcService to bind to it (because of the setter name) but the id of CalculatorService is calculatorService.
Change setCalcService(...) to setCalculatorService(...) in AbstractCalculatorEndpoint

Apache CXF + resource handler with embedded jetty in osgi with spring dm

I'm trying to run an apache cxf endpoint in an equinox osgi environment with jetty 7. I need the endpoint to be on address http://x.x.x.x:8080/ws/endpoint1 and have static resources on the root path http://x.x.x.x:8080/*.
I have a dedicated bundle for this purpose containing the cxf libraries. Spring dynamic modules are part of my target platform.
After some research I tried to start the jetty webserver in my spring application context.

My WebService Endpoint is declared with:
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<bean id="someService" class="abc.xyz.SomeClass" />
<jaxws:endpoint id="endpointId" implementor="#someBean"
address="/endpoint1">
</jaxws:endpoint>
Unfortunatly this is not working. I can reach the static resources, but not the webservice.
The log says, the WebService is published under address /endpoint1. No warnings, no exceptions.
When I change the address of the webservice to its full url
<bean id="someService" class="abc.xyz.SomeClass" />
<jaxws:endpoint id="endpointId" implementor="#someBean"
address="http://x.x.x.x:8080/ws/endpoint1">
</jaxws:endpoint>
the webservice works fine, but the static ressources are not available any more.
Is it possible with a configuration like this to publish an endpoint to a running jetty with relative address? Or am I totally wrong? Most examples I found on the web use a web.xml, but I'm not working with an application server like tomcat and need the application to be a standalone eclipse app.
Spend the whole last two nights on this, any help is highly appreciated.
Kind regards,
Onno

ClassCastException Thrown When Getting X509Certificate in Jetty-7.1.6.v20100715

The filter I wrote threw ClassCastException
[Ljava.security.cert.X509Certificate; cannot be cast to java.security.cert.X509Certificate
when I tried to cast an Object extracted from the ServletRequest attribute, i.e.
public void doFilter(ServletRequest req, ServletResponse res, FilterChain filterChain) throws
IOException, ServletException
{
X509Certificate cert = (X509Certificate) req.getAttribute("javax.servlet.request.X509Certificate");
System.out.println("cert dn " + cert.getSubjectDN().toString());
filterChain.doFilter(req, res);
}
As I dug deeper I understood that exception like this was most probably caused by different classloaders though they are of same class type. How do I resolve this?
Thanks

I don't think it's a duplicate class problem in this case, because X509Certificate is contained in the core JRE libraries. There is, afaik, no other library which provides this abstract class.
I think the problem is the getAttribute() returns an array of X509Certificate objects, whereas you cast it down to a single object. The beginning [L of the ClassCastException message indicates that the object returned is an array.
Try casting to an array of certificates:
X509Certificate[] cert = (X509Certificate[])
req.getAttribute("javax.servlet.request.X509Certificate");
Also, i think that you should retrieve the object from getAttribute() and use instanceof checks to see whether it contains the desired types and maybe handle them differently.

During Spring unit test, data written to db but test not seeing the data

I wrote a test case that extends AbstractTransactionalJUnit4SpringContextTests. The single test case I've written creates an instance of class User and attempts to write it to the database using Hibernate. The test code then uses SimpleJdbcTemplate to execute a simple select count(*) from the user table to determine if the user was persisted to the database or not. The test always fails though. I was suspect because in the Spring controller I wrote, the ability to save an instance of User to the db is successful.
So I added the Rollback annotation to the unit test and sure enough, the data is written to the database since I can even see it in the appropriate table -- the transaction isn't rolled back when the test case is finished.
Here's my test case:
#ContextConfiguration(locations = {
"classpath:context-daos.xml",
"classpath:context-dataSource.xml",
"classpath:context-hibernate.xml"})
public class UserDaoTest extends AbstractTransactionalJUnit4SpringContextTests {
#Autowired
private UserDao userDao;
#Test
#Rollback(false)
public void teseCreateUser() {
try {
UserModel user = randomUser();
String username = user.getUserName();
long id = userDao.create(user);
String query = "select count(*) from public.usr where usr_name = '%s'";
long count = simpleJdbcTemplate.queryForLong(String.format(query, username));
Assert.assertEquals("User with username should be in the db", 1, count);
}
catch (Exception e) {
e.printStackTrace();
Assert.assertNull("testCreateUser: " + e.getMessage());
}
}
}
I think I was remiss by not adding the configuration files.

Some of this I've inherited from someone else. I wouldn't have used the proxying that is going on here because I'm not sure it's needed but this is what I'm working with.
Any help much appreciated.
IIRC, Hibernate (and other O/R mappers) delay the database INSERT and UPDATE statements until the transaction commit. The SELECT then does not see the data, as it is not yet written. Try explicitly requesting a session flush.
See also the documentation for an explanation and example:
http://docs.jboss.org/hibernate/core/3.3/reference/en/html/objectstate.html#objectstate-flushing
Doesn't transactionInterceptor automatically commits?
http://www.docjar.com/html/api/org/springframework/transaction/interceptor/TransactionInterceptor.java.html
Line 117:
commitTransactionAfterReturning(txInfo);
By default the flush mode should be auto, so there should be an implicit flush when commit is performed. I have the same problem and had to solve it by manually calling flush. That is very unsatisfying because my existing code depends on auto-flush before migrating to Spring transation manager. I wish there is a way to tell org.springframework.orm.hibernate3.HibernateTransactionManager to flush after commit.
