Exception during application startup

Guys,

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

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

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

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

Here it is.

You have to set the dataSource of the JdbcDaoSupport:

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.

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

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

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

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

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

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.

I'm posting my complete sources here.

My applicationContext.xml as below;

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

        </props>
      </property>
    </bean>

</beans>

My service class from which I call the DAO implementation:

And finally my DAO implementation class:

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

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 :

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

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

How do you get the AdminServiceImpl bean ?

I instantiate it myself in the jsp currently.

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

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.

(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 ?

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>

<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>

<servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

<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.

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?

Yes.
