Were there any deployment errors in the application?? Did you configure struts in web.xml?? Is there a jsp named product.jsp in the root folder of your application?? Is there a class TestProduct.struts.ProductListAction in your application??

Hi Ankit,

Thanks for Reply. While running application GlassFish V2 gave following Exception. But i think that is related to Validation Framework and that should not be the cause of not even loading the application. (Loading even starting Page).

Following is the struts-config.xml entry in web.xml




Follwing the product.jsp under /WEB-INF folder.




But currently TestProduct.struts.ProductListAction is not there But that should not cause problem of even not displaying first jsp page itself.

Thanks in Advance.

Hi Ankit,

I commented out snippet for /ProductList action in the strut-config.xml in. But in vain.

Thanks.

Please show the complete declaration of struts servlet in web.xml i.e. the <servlet> and <servlet-mapping> tag used to declare struts in web.xml. Also are there files named validator-rules.xml and validation.xml in WEB-INF directory??

Hi Ankit,

Last when i ran the application i got following error.(in bold)


Error occurred during application loading phase. The application will not run properly. Please fix your application and redeploy. WARNING: com.sun.enterprise.deployment.backend.IASDeploymentException: ContainerBase.addChild: start: LifecycleException: javax.servlet.UnavailableException: Cannot load a validator resource from '/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml' run-deploy: Browsing: http://localhost:14521/Inventory/ run-display-browser:


Could you let me know what went wrong here other than validator framework. Moreover i have change form bean extending to ActionForm instead of ValidatorForm.

Hi All,

Now i'm getting HTTP Status 500 and getting following exception on the display page.

exception javax.servlet.ServletException: javax.servlet.jsp.JspException: Cannot retrieve definition for form bean null on action /Product root cause javax.servlet.jsp.JspException: Cannot retrieve definition for form bean null on action /Product.


Do not know where the error lies or what is going wrong?

Please Help on this.
