    Using diffferent HibernateConfiguration for each DataSource

    Hello,

    We are using SmartClient release 8.3 12/12/12.

    We need to use different hibernate configuration for each DataSource. I understand that that this can be achieved by using sprint and providing config bean for each DataSource but the problem is that we don't use spring at all. Is there another way to get this functionality?

    Furthermore, I wanted to know, if I am setting this properties in server.properties

    Code:
    hibernate.config.lookupStyle: factory
hibernate.config.className: com.msp.smartclient.HibernateSessionFactoryFetcher
    How do I know what methods I need to write in the HibernateSessionFactoryFetcher class? (I couldn't find any documentation about it)

    Thank you.

    Update: I still need answers for the questions above, but besides that I am getting NullPointerException at at com.isomorphic.hibernate.HibernateDataSource.initConfigAndSessionFactory(HibernateDataSource.java:549)

    can you please tell me what is throwing this exception?

      About the NPE, we would need at least the server logs for the request (always include this).

      At the moment, Spring is the only way to have multiple Hibernate configurations. However if you let us know why you think you need multiple configurations, there may be another approach we could suggest.

        Ok, so...

        We setup a WebApplicationContext and this is the spring file that is being loaded:

        Code:
        <?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <bean id="hibernate_test"
          class="com.msp.smartclient.HibernateConfigurationFetcher">

        <constructor-arg value="hibernate_test" />

    </bean>

</beans>
        This is the code for the HibernateConfigurationFetcher class:

        Code:
        package com.msp.smartclient;

import com.msp.dao.DaoFactory;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.springframework.beans.factory.FactoryBean;

/**

    public HibernateConfigurationFetcher() {
    }

    /**

     */
    public HibernateConfigurationFetcher(String hibernateConfiguration) {

        this.hibernateConfiguration = hibernateConfiguration;

    }

// ------------------------ INTERFACE METHODS ------------------------

    }

     */

    /**

     */
    @Override
    public Object getObject() throws Exception {
        return DaoFactory.getDaoFactory().getSessionFactory(String.format("%s.cfg.xml", hibernateConfiguration));
    }

    /**

    @Override
    public Class getObjectType() {
        return SessionFactory.class;
    }

    /**

    @Override
    public boolean isSingleton() {
        return false;
    }

// -------------------------- OTHER METHODS --------------------------

    /**

     */
    public Configuration getConfiguration() throws Exception {
        return DaoFactory.getDaoFactory().getConfiguration(String.format("%s.cfg.xml", hibernateConfiguration));
    }
}
        Here is the DataSource that is being fetched:

        Code:
        return DataSource.fromXML(
                        "<DataSource ID=\"" + s + "\" configBean=\"hibernate_test\" serverType=\"hibernate\" dropExtraFields=\"true\" beanClassName=\"com.msp.dao.entities.GenericTask\" >" +
                                "<fields>" +
                                "   <field name=\"id\"/>" +
                                "   <field name=\"name\" treeField=\"true\" canFilter=\"true\"/>" +
                                "   <field name=\"generatedId\" />" +
                                "   <field name=\"parent\" valueXPath=\"parentTask/id\" />" +
                                "   <field name=\"timeCreated\" type=\"date\"/>" +
                                "</fields>" +
                                "<serverObject className=\"com.msp.smartclient.dmihandler.TreeDMIHandler\"/>" +
                                "</DataSource>"
                );
        2. Reminder to answer the "hibernate.config.lookupStyle: factory" question that I mentioned above.

        3. Why I need multiple configuration? Because one of our main feature is that we consolidate data of several software into our software. This is why we need to allow showing data in ListGrid, TreeGrid, etc with DataSource that is using different hibernate configuration. Furthermore, we allow the customer (with our guiding GUI) to configure these other hibernate configuration after the software is installed so this means that the defined hibernate configuration files aren't exist in the classpath but in the tomcat folder. We already have factory that provide HiberateConfiguration and SessionFactory based on the wanted data but I am having troubles using it since you only provide this kind of feature via spring. It was very helpful if you had a feature that before executing each DataSource it would go through a defined factory class that would provide the DataSource with the HibernateConfiguration or SessionFactory based on the DataSource data.

        Thank you.

          Again please provide the complete log for the request (not *just* the stack trace). This is always required. The full log can contain a lot of context that may not seem important to you, but is to us.

          As far as making it possible to use multiple Hibernate configs without Spring, that would be a valid Feature Sponsorship if you really need it.

          "lookupStyle" is documented under ServerObject.lookupStyle.

            and what I meant is that if I'm using these properties in server.properties file:

            Code:
            hibernate.config.lookupStyle: factory
hibernate.config.className: com.msp.smartclient.HibernateSessionFactoryFetcher
            how do I know what methods I need to implement in the HibernateSessionFactoryFetcher class? because I couldn't find any information about that.

              The log we asked for was the complete log for the failing request. This is a log from startup showing some unrelated DataSourceLoader issue.

              Again, see the docs for ServerObject.lookupStyle for information on how to use lookupStyle:"factory". Note that lookupStyle:"factory" and lookupStyle:"spring" are distinct settings - "factory" does not require Spring.

                I provided all the logs I get. I don't know what else I can show you. You can clearly see in the above messages all the information you need. So please try to help me.

                If you think there is more information I can provide, please guide me to how to provide it.

                  OK I figured out what is my problem.

                  The bean must extends either org.springframework.orm.hibernate3.LocalSessionFactoryBean or org.springframework.orm.hibernate4.LocalSessionFactoryBean. The null pointer exception occurred because we have the hibernate3.LocalSessionFactoryBean class in the classpath but not the hibernate4.LocalSessionFactoryBean plus the fact that the bean that is configured in the datasource configBean attribute doesn't extends one of the above classes.

                  Since we already have factory class that handles the Configuration and SessionFactory we have 3 choices.

                  1. Have both hibernate3.LocalSessionFactoryBean and hibernate4.LocalSessionFactoryBean in the classpath in order to avoid the null pointer exception and use this class in the bean definition. This option will work but is very ugly.

                  2. Make the class in the bean definition extends the LocalSessionFactoryBean class and override some of the functions in order to achieve what we need but I see that the getConfiguration method in LocalSessionFactoryBean is final and I can't override it. So this options is problematic.

                  3. Feature sponsorship option. Have you configure an attribute on the DataSource that will allow me to configure different Configuration and SessionFactory for each DataSource.

                  What do you think I should do? If option number 3, how much time it will take you?

                    About the logs - the log that the forums prompts you for, and that we will always request if you forget to provide it, is again the "complete log for the failing request". Not the log from server startup - the complete log for the failing request.

                    You showed an NPE, then when we asked for the complete log for the request that led to the NPE, you provided an unrelated log without that error - obviously not the right log.

                    Hopefully that is clear. We still need this log in order to understand how you could get this NPE.

                    And you still need to read the docs for ServerObject.lookupStyle "factory" because you seem to think this is related to Spring, but it isn't.

                      I provided all the logs I have. I think I know why there is nullpointer exception please read the last post. For the lookup style factory issue, I found what I was looking for and I know that it's NOT related to spring.

                      Just to be sure, here is the entire log from the click of the button that generate the DataGrid to the exception.

                      Code:

                      Please read the last post, I pretty sure I know why there is nullpointer exception.

                        I've noticed that I was logged with another user. This is the user with the premium support plan.

                          A developer has been assigned to look into this, but he is in a European timezone so please bear with us.

                            Thank you. European timezone is good for me because I'm from Israel.
