Hibernate Connection using C3P0 and Postgresql

I am trying to get an application(jadasite) up and running using postgresql and glassfish. The app designers recommend tomcat and mysql. I can not really use tomcat and mysql for this app atm. The application uses JPA so postgresql should be no problem. The designers do mention that postgresql/many other db's should work.

So here is what I have done Using the following two pages as a reference:

Hibernate Docs

Jadasite forums

jada.properties

log4j.directory=/tmp
hibernate.connection.password=password
working.directory=/tmp
encryption.key=fVOew3eAhr+hdZ9eQLeEtw\=\=
hibernate.connection.url=jdbc\:postgresql:dev-rdbms.example.com:5432/jada"/>
hibernate.connection.driver_class=org.postgresql.drivers

persistence.xml(parital)

<property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>
<property name="hibernate.connection.username" value="jada"/>
<property name="hibernate.connection.password" value="password"/>
<property name="hibernate.connection.url" value="jdbc:postgresql://dev-rdbms.example.com:5432/jada>
<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
<property name="hibernate.current_session_context_class" value="thread"/>
<property name="hibernate.connection.provider_class" value="org.hibernate.connection.C3P0ConnectionProvider"/

I then used mysql2psql to make a postgresql compatible db dump, loaded all data and created appropriate users with appropriate permissions and acces.(tested via psql from server glassfish runs on as well)

So after making the changes I put the lastest postgresql jdbc 4 driver into the applications WEB-INF/lib directory. Made a new war file and deployed it to my glassfish v3.01 server.

I get the following errors. Which appear to me to say C3P0 can not find the JDBC drivers(located in apps WEB-INF/lib directory and also in the glassfish domains lib directory)

Does anyone see anything wrong with my connection paramaters or have any idea how C3P0 could be missing these drivers?

Edit

I did see some issues that looked like they were caused by C3P0 not finding the drivers so I did try throwing the C3P0 jar into the glassfish lib as well but still got the same errors. Here is the error from the comment below in a little nicer fasion and more info.

Two things seem odd here:

1) the stacktrace for ClassNotFoundException does not mention the name of the class that was not found:

Caused by: java.lang.ClassNotFoundException:

This would seem to imply that it is trying to load a class with no name, otherwise you would expect to see the name of the class that could not be found.

2) Not sure if it's just a copy and paste mistake, but in the snippet of your configuration above, you are missing the end-quote on this line:

<property name="hibernate.connection.url" 
     value="jdbc:postgresql://dev-rdbms.example.com:5432/jada>

which would make for malformed XML.

3) When you say

Made a new jar file and deployed it to my glassfish v3.01 server.

Do you mean to say you made a new "war" file, not "jar"? You need to make sure that the postgres jdbc jar is on glassfish's classpath ultimately.


Let try this:

You use EJBs right (JPA means EJB)? So, you have at least one EAR, one JAR and possible one WAR, right? You know, JARs cannot access WARs files. If your postgresql jdbc 4 driver is on WAR/WEB-INF/lib your JARs (which need it) cannot access.

Try put your lib in a EAR lib (look for glassfish doc for that, but is something like EAR/WEB-INF/lib too) or put it on server libraries (something like GLASSFISH_DIR/lib/classes)


Why do you have hibernate.connection.driver_class=org.postgresql.drivers in the properties file? Shouldn't it be org.postgresql.Driver instead?

Edit:

Ah! Looks like Jadasite uses the properties file to load the driver class.

From com/jada/jpa/connection/JpaConnection.java class:

67      
68      public void init(String driver, String url, String user, String password) throws Exception {
69          this.driver = driver;
70          this.url = url;
71          this.user = user;
72          this.password = password;
73          
74          HashMap<String, String> map = new HashMap<String, String>();
75          map.put(Environment.DRIVER, driver);
76          map.put(Environment.URL, url);
77          map.put(Environment.USER, user);
78          map.put(Environment.PASS, password);
79          factory = Persistence.createEntityManagerFactory("jadaSite", map);
80      }

Which is read as (in com/jada/system/Initializer.java):

 111            if (requireInstall) {
 112                if (!installCompleted) {
 113                    log("Installation has not been done.  Skipping custom initialization.");
 114                    log("Please proceed to installation and remmember to restart before continue.");
 115                    log("Awaiting installation....");
 116                    return;
 117                }
 118                try {
 119                    Properties installProperties = installer.getConfigProperties();

Which comes from (in com/jada/install/process/Installer.java):

 345        public Properties getConfigProperties() throws IOException {
 346            String filename = servletLocation + Constants.CONFIG_PROPERTIES_FILENAME;
 347            File file = new File(filename);
 348            FileInputStream input = new FileInputStream(file);
 349            Properties properties = new Properties();
 350            properties.load(input);
 351            return properties;
 352        }

Which is read from the file (in com/jada/util/Constants.java):

 275        public static final String CONFIG_PROPERTIES_FILENAME = "WEB-INF/jada.properties";
