Need Help

Hi All,

I'm trying to run class having a below method but getting an exception while running. I have check but wnat to know what is wrong so that I make necessary correction to fix this exception.
SPRING_CONTEXT_FILE: ist is a string variable pointing to application.xml file.

public static void main(String[] pArgs)
{
try
{ System.out.println(" starting ");
ApplicationContext ctx = new ClassPathXmlApplicationContext(SPRING_CONTEXT_FILE);
System.out.println("before applicationbean name");
CoreBatchVehicleListApp app = (CoreBatchVehicleListApp) ctx.getBean(APPLICATION_BEAN_NAME);
System.out.println("After applicationbean name");
// get the key framework instances if any of these are missing we will get a runtime exception

Thanks

It will be helpful, if you can post here your application.xml is well..

What type of help do you need?

I can't tell by your subject line. Maybe you can edit your message and change your topic title to be more specific.

Thanks

Please change your subject line so I can see what help you need.

"Need Help" tells me nothing and I go by the subject header.

Well, it looks like a classpath issue.
Can you override the Factory provided constants and use the actual names in your main class? (application.xml & Application bean)
Also, is your ApplicationContext file placed at application root or in classpath?
