Re: Struts basic forwards

Thu, 14 May 2009 04:46:52 -0700

Forgive me, you have reason.

Using urls like:

http://localhost:8180/Tuto/SayHello.do
http://localhost:8180/Tuto/SayGoodBye.do

It show 2 messages the Hello and Goodbye, correctly.

The problem occurs in which the index should be 2 links:

         <html:link action=""> Hello </ html: link>
         Adios <html:link action=""> </ html: link>

Logically if I remove the 2 links the rest of the load index correctly.

The problem is if you can not resolve the action and gives an exception.

Hi Jesús,
first of all without globalforwards block it should work as well.
Then try not to put anything inside those jsp files,
maybe something is wrong there.

In browser entering address like:
http://yourserver/yourapp/SayHello.do
should show hello.jsp where yourapp is application context or nothing
if it's run as a root.

You can also show more of that exception, not just first line.

Best greetings,
Paweł Wielgus.

Hi for all.

Firstly thank you all for reading this email, I hope you can help me,
I'm starting with struts.

I want to do something as simple as 2 links to pass control to 2
different JPS.
as follows.

        <html:link action=""> Hello </ html: link>
        <html:link action=""> Bye </ html: link>

In struts-conf.xml have defined the following action-mappings and
global-forwards

    <global-forwards>
        <forward name="welcome" path="/Welcome.do"/>
        <forward name="sayhello" path="/SayHello.do"/>
        <forward name="saygoodbye" path="/SayGoodBye.do"/>
    </ global-forwards>

    <action-mappings>
        <action path="/Welcome" forward="/welcomeStruts.jsp"/>
        <action path="/SayHello" forward="/WEB-INF/hello.jsp"/>
        <action path="/SayGoodBye" forward="/WEB-INF/bye.jsp"/>
    </ action-mappings>

And the end result is an exception type

javax.servlet.ServletException: Could not initialize class
org.apache.jasper.runtime.BodyContentImpl

I believed that this would work, otherwise I did not understand how
struts work.
Someone can tell me if my fault or failure of a dependency?

Tnks for all :)
