Newbie HelloWorld Struts.xml problem

[Ron Ingram]

Catching an exception when trying to run the HelloWorld tutorial... Can someone help please? Seems to be a struts.xml format issue

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <constant name="struts.devMode" value="true" />

    <package name="basicstruts2" extends="struts-default">

        <interceptors>
        </interceptors>

        <global-results>
        <global-results>


        <action name="index">
            <result>/index.jsp</result>
        </action>

        <action name="hello" class="src.org.apache.struts.action.HelloWorldAction" method="execute" ></action>
        <result name="success">/HelloWorld.jsp</result>

    </package>

</struts>

Looks like your interceptors element is not complete, as you have not specified a interceptor or interceptor stack. I'd recommend deleting it, as well as the global-results tag that does not have an end tag.

Thank you, now I'm back to my original exception where I'm not following the struts.xml format. Exception below:

This is my struts.xml file now:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <constant name="struts.devMode" value="true" />

    <package name="basicstruts2" extends="struts-default">

        <action name="index">
            <result>/index.jsp</result>
        </action>

        <action name="hello" class="src.org.apache.struts.action.HelloWorldAction" method="execute" ></action>
        <result name="success">/HelloWorld.jsp</result>

    </package>

</struts>

[Joe Ess]

Take a hard look at that second action declaration.

[Ron Ingram]

Thanks for not giving it away.. I did need to really look over it and follow my tags.. I moved the </action> to the proper place after the </result>.

Appreciate your time. R

[Mohana Rao Sv]

method="execute". you can take off by default execute method would be called. Because we're overriding it.
