Exception during application startup

[Joe Harry]

Guys,

I have a Spring web application running in Tomcat. When I try to bring the application up, I get the following error.

Mar 16, 2010 9:55:29 PM org.springframework.web.context.ContextLoader initWebApplicationContext

Is the CGLIB what it complains is a library?? Should that be added as a dependency?

[Joe Harry]

After a bit of self exploration, I found out that I missed something in the applicationContext.xml configuration. Later I corrected it and now this is the error that I face:

Here is my applicationContext.xml snippet:

</beans>

Here IAdminDAO is my DAO interface and AdminDAOImple is the implementation class.

[Christophe Verré]

Can you show AdminDAOImpl.java ? It looks like you need to set a dataSource or a jdbcTemplate in that bean.

[Joe Harry]

Here it is.

   

public class AdminDAOImpl extends JdbcDaoSupport implements IAdminDAO {

    /**
     * @{inheritDoc}
     */    
    public int save() throws Exception {
        //getJdbcTemplate().update("insert into division values");
        return 0;
    }
}

[Christophe Verré]

You have to set the dataSource of the JdbcDaoSupport:

<bean id="adminDAO" parent="txProxyTemplate">  
	<property name="target">  
		<bean id="adminDAOImpl" class="com.myproj.fgen.core.persistence.admin.impl.AdminDAOImpl">  
			<property name="dataSource" ref="dataSource" />
		</bean>
	</property>  
	<property name="proxyInterfaces" value="com.myproj.fgen.core.persistence.admin.IAdminDAO" />  
</bean>

[Joe Harry]

Oh yes, it worked. I did forget to specify the datasource property. The server startup was without any exceptions. Now I have to check how the declarative transaction would work by forcefully introducing some exceptions during insertion into the table. Will post here if I face any difficulties.

[Joe Harry]

Getting a NullPointerException in the line below in my AdminDAOImpl.java

getJdbcTemplate().update("insert into division (div_name) values (?)"); 

Looks like the getJdbcTemplate() returns me null. What could be the reason? Am I missing any configuration information??

[Joe Harry]

Do I still miss anything in my applicationContext.xml declaration?

[Christophe Verré]

If you want to use the JdbcTemplate (or SimpleJdbcTemplate), you need to set it explicitly.

public class AdminDAOImpl extends JdbcDaoSupport implements IAdminDAO { 
	...
	public void setDataSource(DataSource dataSource) {
        this.jdbcTemplate = new JdbcTemplate(dataSource);
    }

}

Or you can create a JdbcTemplate in your context file, and assign the DataSource to it, then wire it to your Dao.

[Joe Harry]

public void setDataSource(DataSource  dataSource) {
    this.jdbcTemplate = new JdbcTemplate(dataSource);
}

Seems not to work, since setDataSource is final (in the JdbcDaoSupport) and cannot be overridden. I'm anyways wiring it in the applicationContext.xml as you can see it in my post above.

[Joe Harry]

I'm posting my complete sources here.

My applicationContext.xml as below;

      <property name="proxyInterfaces" value="com.myprog.fgen.core.persistence.admin.IAdminDAO" />
    </bean>

</beans>

My service class from which I call the DAO implementation:

public class AdminServiceImpl implements IAdminService {

    /**
     * @{inheritDoc}
     */
    public List getAllDivisions() {
        return null;  //To change body of implemented methods use File | Settings | File Templates.
    }

    /**
     * @{inheritDoc}
     */
    public List getAllTypesForDivision(long divisionId) {
        return null;  //To change body of implemented methods use File | Settings | File Templates.
    }

    public int saveDivision() {
        IAdminDAO adminDaoImpl = PersistenceFactoryImpl.getInstance().getAdminPersistence();
        try {
            adminDaoImpl.save();
        } catch (Exception e) {
            System.out.println("Exception caught...check in the db if the transaction is rolled back or not...");
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }
        return 0;
    }
}

And finally my DAO implementation class:

public class AdminDAOImpl extends JdbcDaoSupport implements IAdminDAO {

    /**
     * @{inheritDoc}
     */    
    public int save() throws Exception {
        String div = "divtwo";
        String typ = "typTwo";
        System.out.println("The GETJDBCTEMPLATE is ***************** " + getJdbcTemplate());
        getJdbcTemplate().update("insert into division (division_name) values (?)", new Object[] {div});
        getJdbcTemplate().update("insert into type (type_name) values (?)", new Object[] {typ});
        return 0;
    }
}

So System.out.println("The GETJDBCTEMPLATE is ***************** " + getJdbcTemplate()); prints null???

[Christophe Verré]

Seems not to work, since setDataSource is final (in the JdbcDaoSupport) and cannot be overridden.

Sorry, the jdbcTemplate is supposed to be instanciated when the DataSource is set. So the xml file is correct.
What puzzles me now is the following line :

IAdminDAO adminDaoImpl = PersistenceFactoryImpl.getInstance().getAdminPersistence();  

Is this IAdminDAO instance retrieved by the Spring container ? If not, that would explain why the jdbcTemplate is not set.

[Joe Harry]

I changed them accordingly as below but still there seems to be the exception:

How do you get the AdminServiceImpl bean ?

[Joe Harry]

I instantiate it myself in the jsp currently.

How to get the AdminServiceImpl wired in the applicationContext.xml?

[Christophe Verré]

I instantiate it myself in the jsp currently.

If it's not managed by Spring, the wiring process will not magically happen
You should get it from a servlet, not from a JSP. You can retrieve it any way you would for a classic application, via the ApplicationContext.

ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(getServletContext());
Object myDao = context.getBean("adminService");

(It would even be better to autowire the service to the controller, so you wouldn't need that)

I hope you have everything configured properly. Your context file doesn't seem to have a correct name. It should be named [servlet-name]-servlet.xml, where [servlet-name] is the name you have given to the DispatcherServlet. Are you using a tutorial ?

[Joe Harry]

Here is my web.xml:

<web-app>
  <display-name>Struts Blank Application</display-name>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
  </context-param>
  
  <listener>
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>  

  <!-- Standard Action Servlet Configuration -->
  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
 </servlet>


  <!-- Standard Action Servlet Mapping -->
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>


  <!-- The Usual Welcome File List -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

</web-app>

I'm just testing this app set up and all what I'm doing is just calling the AdminServiceImpl implementation in my index.jsp. Is there any additional configuration that I need to do to wire up the service?? I'm using Struts 1.3.10 framework.

[Christophe Verré]

Aaaah, ok You're not hiding some information So you are using the ContextLoaderListener. You can now access the context via WebApplicationContextUtils:

ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(application);

The "application" is the jsp implicit object?? Am I right?

[Christophe Verré]

Yes.
