Hey all,
I'm running into an issue using guice-persist on the server side of a GWT
application.
I'm using the following persistence.xml w/ a JPA annotated DurableUser
class:
<persistence xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";
version="2.0">
<persistence-unit name="db-manager">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.turms.server.database.DurableUser</class>
<properties>
<property name="hibernate.cache.use_second_level_cache"
value="false"/>
<property name="hibernate.connection.drive_class"
value="com.mysql.jdbc.Driver"/>
<property name="hibernate.connection.url"
value="jdbc:mysql://localhost:3306/xxxXX"/>
<property name="hibernate.connection.username" value="xx"/>
<property name="hibernate.connection.password" value="xx"/>
<property name="hibernate.connection.pool_size" value="1"/>
<property name="hibernate.dialect"
value="org.hibernate.dialect.MySQLDialect"/>
<property name="hibernate.hbm2ddl.auto" value="create"/>
<property name="hibernate.id.new_generator_mappings"
value="true"/>
</properties>
</persistence-unit>
</persistence>
in my server's service class, I create an injector w/ my DatabaseModule
class (provides a UserDao) and a new JpaPersistModule("db-manager")
On initialization of my server's service class, I call:
PersistService service = injector.getInstance(PersistService.class);
service.start();
this results in the following exception being thrown:
java.lang.NoClassDefFoundError: com/xxxXX/server/database/DurableUser
(wrong name: com/xxxxx/server/database/DurableUser)
One thing I noticed is that the first path in the exception
(com/xxxXX/server/database/DurableUser) is not quite right..that path
should be com/xxxxx/server/database/DurableUser.
My company name xxxXX, but the last 2 letters should not be capitalized in
the path. I'm not sure where this change is coming from, I dont see any
place where xxxXX is in a package name. The bad path name is the only
problem I can find with my current setup.
My built service (a .war) has the following structure:
XxxXX-1.0
--com.xxxxx.XxxXXWebJUnit
--junit files
--META-INF (empty folder)
--XxxXXWeb
--looks like gwt web stuff in this folder
*--WEB-INF*
* --classes*
* --com*
* --compiled classes*
* --META-INF*
* --persistence.xml*
* *--deploy
--files needed for deployment
--lib
--jars for project
--web.xml
It seems like my persistence.xml is in the right place, so JPA shouldnt
have any trouble locating DurableUser.class
Any help is greatly appreciated!
