error in SimpleFormController

[hakaxh]

Hello,

I need some help with my Controller which extends an SimpleFormController. My application is deployed in Tomcat 6.0. When I look into the logfiles in Tomcat I can see that the variables written by Log4J has been assigned with correct values. I do that in the method doSubmitAction.

The next statement to be executed is in my case to create a project which I do in the ProjectService object by the method createProject.

This is my error;Line 69 is the statement projectService.createProject(projectDao). I don't know why this happens. Maybe someone can help me with this?

Your service likely isn't wired up correctly, ie, its not being initialized hence the infamous NPE.

Agreed. Specifically, it looks like you need a projectService set as a property on your controller, and it isn't being set.

In my dispatchere-servlet.xml i have configured a bean name like this;

<bean name="/createProject.htm" class="businessLayer.controller.CreateProjectContr oller">
<property name="formView">
<value>createProject</value>
</property>
<property name="successView">
<value>readProject</value>
</property>
</bean>

I wonder how to configure my ProjectService as att attribute in this file?
