As indicated in my earlier post in this forum, I am having trouble with a ClassCastExeption when using
- mvn gwt:run (GWT Maven plugin using Jetty)
- JPA / Hibernate's EntityManager
The error is:
javax.persistence.PersistenceException:
[PersistenceUnit: name] Unable to build EntityManagerFactory
...
Caused by: org.hibernate.HibernateException: Could not instantiate dialect class
Caused by: org.hibernate.HibernateException: Could not instantiate dialect class
...
Caused by: java.lang.ClassCastException: org.hibernate.dialect.MySQLDialect cannot be cast to org.hibernate.dialect.Dialect
Caused by: java.lang.ClassCastException: org.hibernate.dialect.MySQLDialect cannot be cast to org.hibernate.dialect.Dialect
...
(see full stack trace below)
When I do not specify hibernate.dialect in persistence.xml I get other ClassCastException. Deploying to Tomcat works fine.
This happens with GWT 2.3 (GWTP 0.6, GWT Maven Plugin 2.3.0-1) and GWT 2.4 (GWTP 0.7-SNAPSHOT, GWT Maven Plugin 2.4.0).
Maybe this comes from a dependency conflict?

Hi,
I recently migrated an application from GWT 2.2, GWTP 0.5.1 to GWT 2.3 and GWTP 0.6 then GWT 2.4 and GWTP 0.6.
When I moved from GWT 2.2 to 2.3 I added:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId> <!-- Required by GWT 2.3 for bean validation -->
</dependency>
to the Hibernate dependencies:
<!-- JPA/Hibernate dependencies -->
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId> <!-- Required by GWT 2.3 for bean validation -->
</dependency>
And the application works fine when run via mvn gwt:run and when deployed to Tomcat 7.
I'm not sure but the issue you are having may be related to JNDI look ups which don't work in hosted mode.
I have a hosted mode PU and a non-hosted mode PU configured via web.xml:
<context-param>
<param-name>PU-NAME</param-name>
<param-value>HSQLDB-HOSTED-MODE-PU</param-value>
<!-- <param-value>HSQLDB-TOMCAT7-CP-PU</param-value> -->

Thanks Rob (and everybody) for trying to help! Unfortunately I had no luck yet and the ClassCastException is still there in jetty mode. I should have mentioned that it only happens in combination with "install" goal.
mvn install jetty:run
The ClassCastException is reported in console in tab "Jetty" before accessing any URL of the webapp.
BTW: I also don't understand why I can see my slf4j/log4j output only with "install" (and "gwt:run") goal.
Not sure if that worth mentioning, but without "install" on the other hand, there is a 404 error when accessing the problematic URL (see corresponding stacktrace below). Dispatcher is invoked and on server side (in the handler), a Hibernate based service is used (again, this works in Tomcat).
Currently it looks like I can only get rid of all exceptions in jetty by
- using install: mvn install gwt:run
- disabling the use of the service in the handler
- disabling the two lines in DispatchServletModule to setup Hibernate:
// logger.info("Setting up JPA");// install(new JpaPersistModule("name"));// logger.info("Starting JPA PersistFilter");// filter("/*").through(PersistFilter.class);
Regarding JNDI lookups, I don't thik we use it as we directly talk to DB using MySQL driver.
Any hints are greatly appreciated!

When running in hosted mode do you place a copy of the JDBC driver for MySQL in WEB-INF/lib (the same file you place in tomcat\lib)?
e.g. for HSQLDB this would be hsqldb-2.0.01-rc1.jar

Yes, mysql connector is in lib folder, see the "blue JAR" in list below.
Here is also my web.xml and the listener class:

Update: As we need a solution soon, I tried to avoid the guice portion as a last resort.
The (bad?) idea: Skipping the two "red" lines in listener class (see earlier post) and instead creating BaseDao class similar to yours Rob, which creates an EntityManagerFactory once:
public abstract class BaseDao {
protected static String puName = "name";
private static boolean initialised = false;
private static EntityManagerFactory emf = null;
public static EntityManager createEntityManager() {
if (! initialised) {
emf = Persistence.createEntityManagerFactory(puName);
initialised = true;
}
return emf.createEntityManager();
}
}
Even now I get the ClassCastException with "mvn gwt:run":

Hi,
-> Caused by: java.lang.ClassCastException: org.hibernate.dialect.
In your persistence.xml is the dialect set correctly? e.g. <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
Also there is no hibernate-validator-4.1.0.Final.jar in your list (as per my previous post):
<dependency>
<groupId>org.hibernate</groupId>
And you have a couple of JBoss libs? Are you setting transaction-type="RESOURCE_LOCAL" or "JTA"?
Cheers
Rob

Hi Rob,
I'm also working with Alexander on this.
Thanks for your help.
The dialect is set as you mention. Actually when I remove the dialect completely, I still see it find dialect in the console but the error becomes:
org.hibernate.engine.transaction.internal.jdbc.JdbcTransactionFactory cannot be cast to org.hibernate.engine.transaction.api.TransactionFactory
Transaction type is RESOURCE_LOCAL.
It seems to work when deployed in tomcat. Also when I do jetty:run, the hibernate parts appear to work from the console (the app doesn't because not everything is configured). It is only happening in gwt:run, which seems pretty strange, but there must be some incorrect reference or jar.
Thanks,
Lee

HI,
As far as I can recall the only time I received a class cast exception was when I left out the Hibernate validation dependency.
Can you try adding it in?
And then try:
mvn gwt:clean
mvn clean
mvn install
mvn gwt:run

At least the three "Caused bys" did not change (and probably all details remained the same too) yes. So it's (most likely) still the same stacktrace from original post (see also below). If you want, I can double check tomorrow.
I've also posted a "short" summary in other forums that describes what happens when dialect is not set for example:
One thing I didn't mention yet: The class cast exception occurs when hosted mode is started before any page is accessed (which gives HTTP error). It does not get thrown if those two lines are removed
install(new JpaPersistModule("PUname"));
filter("/*").through(PersistFilter.class);
But if you surround them with try catch, the error cannot be caught and logged in Eclipse console; instead it's again reported in console in Jetty tab only. In other words: It's reported only in Jetty console, never in "normal" console (stdout).
Thanks for your patience!
