I have written a small application in struts.

The code for it is as follows:

login.jsp




LoginForm.java





struts-config.xml

Can anybody test it and tell me where I have gone wrong.

Hi,

If I check your action mapping i.e.

<action name = "java" path = "/login" scope = "session" type = "sample.LoginAction">

the action tag is not closed it must be like

<action name = "java" path = "/login" scope = "session" type = "sample.LoginAction" /> instead.

What other error do you get?? Kindly specify.

Thank you

Hi,

Thanks a lot. Now, I think there is no problem with the code. But the problem is in setting up my IDE or ClassPath settings.

I am using myeclipse and configured tomcat. when I start tomcat, it says

A configuration Error Occuredduring statup. Please verify the preference field with prompt: Tomcat JDK Name.


Any help in resolving the issue is highly appreciated.

Looking at login.jsp and LoginForm.java, the properties do not match.
The property name used in the jsp should be a member(with getter and setter methods) in the ActionForm

Please do make the necessary Changes.

It is clearly telling

You have more than one version of 'org.apache.commons.logging.Log'

Hope you added 2 different versions of commons-logging.jar
