OC4J Struts Tutorial

I was following the struts tutorial and everything was fine until I tried to run it. When starting OC4J, I got:
Error initializing server: Error instantiating default application at file:/home/mcdanijr/jdevhome/system9.0.5.1.1605/oc4j-config/application.xml: Constructing UserManager for default:caught oracle.security.jazn.JAZNRuntimeException

Is there some magic I missed?

Nevermind (I think). I switched to 1.4.1 as the JDK for the project and it looks like OC4J is starting OK now.

Any easy Struts tutorial?

I was asked to do a reaaaally basic thing with struts... I have a web application already developed, and I need to be able to go to a certain jsp file, let's just call it view.jsp, by writing view.do in the URL bar instead of view.jsp. I'm finding it really difficult to find a simple tutorial...

Just make another action in action mappings, like this:
<action path = "/ViewView"
                type = "sdmi.emp.web.maintenance.ViewViewAction"
                scope = "request"
                name = "viewForm"
                validate = "false">
            <forward name = "success" path = "/View.jsp"/>
        </action>
        <action path = "/View"
                type = "sdmi.emp.web.maintenance.ViewAction"
                scope = "request"
                name = "viewForm"
                validate = "true"
                input = "/View.jsp">
            <forward name = "success" path = "/employee_search.jsp"/>
        </action>

Links to Struts Tutorial

Hi
Can some one forwards me some good links to struts online tutorial. I have googled a lot on this but could not find a good decent one in lay man terms for begginers.
Thanx,

the links on the left (user and dev guides, faq) are
exhaustive and their how-to guides were the only ones
i neded even when I started years ago. the blank
struts app is the best way to start.nice try, but realistically you'll be pulling your hair out the first week
there have been many, many comments about the learning curve of struts and i've never heard ANYONE say it was well documented before, until now i guess
not trying to be argumentative, just dont' want to give the wrong impression here

How to instantiate object in JSP/STRUTS page?

I worked through the STRUTS tutorial (http://rzserv2.fhnon.de/~lg002556/struts/Doku.html) but I get errors when I try to instantiate an object of a class that is in my WEB-INF/classes directory:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 14 in the jsp file: /BookSerialize.jsp
Generated servlet error:

symbol : class Book

Book book = new Book();
^
The Book.class (and other classes) is in the WEB-INF/classes directory. The BookSerialize.jsp is here:
<%@ page language="java" import="java.beans.XMLEncoder, java.beans.XMLDecoder, java.io.*"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

book.setTitle("A great Book about Struts");
book.setPages(100);
out.println("<member>First Title: " + book.getTitle() + "</member>");
try {
XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(new FileOutputStream("/Sample.xml")));
encoder.writeObject(book);
encoder.close();
} catch(Exception ex) {
out.println(ex);
book.setTitle("A great Book about Struts, Second Edition");
out.println("<member>Second Title: " + book.getTitle() + "</member>");
try {
XMLDecoder decoder = new XMLDecoder(new BufferedInputStream(new FileInputStream("/Sample.xml")));
book = (Book) decoder.readObject();
decoder.close();
} catch(Exception ex) {
out.println("<h1>" + ex + "</h1>");
out.println("<member>Third Title: " + book.getTitle() + "</member>");
%>
</body>
</html:html>
I also get the same error when deploying and (trying to) run on the J2EE 1.3.1 server.
So far, I just used JSP pages working with beans (usebean tag). Is it possible at all to just do a
MyClass myObject = new MyClass();
within a JSP page, if MyClass.class is in the WEB-INF/classes of the web application?
Is there any kind of import missing? Book.class is in the default package, so i can't state it in the page directive/import parameter of the JSP page...
any advice?

I think, I got it: you have to use package names for your classes and avoid the default package. After I used a package name, it was possible to instantiate the object ....

Struts exception handling - Exception handler

Hi ,
I need some help for struts exception handling . Global exception is working fine in my struts application . But I need to show the exception stack trace also in the screen whenever the exception occurs.I guess this can be achieved if we use a custom exception handler instead of struts default exception handler . Can anyone please provide me a sample code to deal with a custom ExceptionHandler class ?
Thanks in advance...
Regards,
BG

The struts provides org.apache.struts.action.ExceptionHandler class for creating the custom exception handlers. All the custom Exception Handlers should extend the ExceptionHandler class and override the execute() method.
//An Example
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ExceptionHandler;
import org.apache.struts.config.ExceptionConfig;
public class CustomExceptionHandler extends ExceptionHandler {
public ActionForward execute(Exception exception, ExceptionConfig config, ActionMapping mapping, ActionForm formInstance,
HttpServletRequest request, HttpServletResponse response) throws ServletException {
try {
// TODO CustomeCode
System.out.println("Exception Handler for the specific error");
}catch (Exception e) {
return (super.execute(exception, config, mapping, formInstance, request, response));
Struts-config.xml File
<exception key="error.system" type="java.lang.RuntimeException"
handler="com.visualbuilder.handler.CustomExceptionHandler" path="/index.jsp" />
Note:- This will transfer the control to the index.jsp after calling the exception handler. In the struts-config.xml we are adding the global exception for RuntimeException. You can add any exception like the previous example to some actions only.
I have taken this example from following link. You may visit it.
http://www.visualbuilder.com/jsp/struts/tutorial/pageorder/38/
I would like if you share knowledge with me.

Hi
What is the Service Pack you are using in weblogic 8.1?that's WebLogic Server 8.1 SP2
Could you send me the test case which you developed to my mail id?it's downloaded from
http://struts.apache.org/download.cgi
version 1.2.7, unzip the source version, get strut-blank.war.
then via weblogic console, copy the war-file to newly created folder
struts-tutorial and deploy it, testing it via
http://localhost:7001/struts-tutorial/
the error message in the browser is
/pages/Welcome.jsp(2): Error in using tag library
uri='http://jakarta.apache.org/struts/tags-html' prefix='html': The Tag
class 'org.apache.struts.taglib.html.FormTag' has no setter method
corresponding to TLD declared attribute 'name', (JSP 1.1 spec, 5.4.1)
probably occurred due to an error in /pages/Welcome.jsp line 2:
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
PS
I found (in the internet) many people having similar problem, when using
WL5, WL6, struts 1.1, struts 1.2+

Strut

hi,
i'm trying to learn strut. can any person tell me the best place to get tutorials on it?
I'm finding it difficult to configure it. I only copied the lib of the to the lib in the WEB-INF of my directory and it didn't work
thanks

There are so many sites for struts tutorials.
www.coreservlets.com/Apache-Struts-Tutorial/
www.roseindia.net/struts/
these are best ones
If you have any doubt you can contact me directly to my mail id
[email protected]
I hope I will suggest you.

Struts DynaActionForm's set method - is it correctly implemented?

Dear people:
I'm trying to make a struts based application that
chain-forwards a single request via two struts action classes.
when a user submits the form post, the first struts action receives the form, does some processings and forwards it to the next action.
however, just before it's forwarding the action,
it needs to change the DynaActionForm settings that it
received to another value:
((DynaActionForm)form).set("event","now_do_this");
and forward to the second action which will receive the
form and read the value which was set up by
the first action.
However, whenever I tried to do this, the second action
simply couldn't get the set up value from first action.
I've searched around couple of struts tutorial sites
and this should be working:
http://www.exadel.com/tutorial/struts/5.2/guess/strutstutorial-dynaform.html
So what I want to know is:
is JDeveloper's (oracle's) struts runtime not properly
functioning?
or, is it my mistake to misunderstand the struts?
Any comments are welcomed.

I have not come across anything call validation.xml.
All that I know is that if validate is specify to true in the ActionMapping inside struts-config.xml, the validate() method in ActionForm will be invoked.
RequestProcessor that ActionServlet delegates to will pass the user to the "input" attribute specified in the ActionMapping inside struts-config.xml. Since action() method actually returns an ActionErrors object whereby if it is empty then consider there are no erros and RequestProcessor will proceed with getting the Action and invoked its execute() method.....which will then return a ActionForward object.......
I hope what i mention is correct.
