My LoginView.jsp Displays A Blank Page

[Caroline Jen]

My LogonView.jsp displays a blank page.  I have no
idea why nothing is written while the
MessageResources.properties file is found.
 
I would have gotton HTTP Status 500 if the
MessageResources.properties is not found or the value
of the corresponding key in the bean:message tag
cannot be picked up.  I did not get any error message.
 I cannot figure out the reason.  Please help.

I have similar questions.  What is the syntax of the
 tag?

Just take the example given by you, are the codes
shown below correct?  Will the default selection
shown?

How To Specify Error Messages For Self-Provided Validation Rules: "mask"


2003-07-07

Thread
Caroline Jen

I am trying to insert entries in the
MessageResources.properties file for 
the error messages generated by automatic validation.
I could find examples for email and date (see below):

errors.email={0} is an invalid e-mail address.
errors.date={0} is not a date.

What should the messages look like for "mask" in the
MessageResources.properties? I used "mask" to provide
a number of validation rules.  How do I specify those
error messages? (I used mask several times.)

Specify Error Messages For Automatic Validation


2003-07-08

Thread
Caroline Jen

I am trying to put entries in the
MessageResource.properties file for the error messages
generated by the automatic validation. 

I used "mask" to provide a number of validation rules.

How do I specify those error messages?  (I used "mask"
for a number of text field to report various errors.) 
I would like to see an example.

I could find examples for email and date:
errors.email={0} is an invalid e-mail address.
errors.date={0} is not a date.

What Is The Proper Location To Place Inputs For Creating A Drop-Down Menu


2003-07-17

Thread
Caroline Jen

I want to put the "label and value" pairs of the 51
states of the U.S. in a file, read in the file into an
ArrayList, and then create a drop-down menu in a .jsp
file.

Question 1.  Where is the proper place to put those
"label and value" pairs?  Create a table in the
database? or put those pairs in a properties file? 
Which directory does this properties file go?

Question 2.  Do I read those pairs into an ArrayList
in the controller servlet?

package org.apache.struts.action Does Not Exist?


2003-07-18

Thread
Caroline Jen

I have been using Struts (jakarta-struts-1.1-rc2) for
about two weeks. I have tested a number of things and
made them work.

Today, while I was trying to compile a model bean (I
have compiled it before without any problem), I got
compilation error: 
package org.apache.struts.action does not exist

I double checked that the struts.jar is in the
$TOMCATHOME\webapps\MyApplication\WEB-INF\lib
directory. What could have happened?

The source code of my model bean is:

package resources.version1;

import javax.servlet.http.*;
import org.apache.struts.action.*;


public class LogonBean {

String userType, userID ,password;

public LogonBean() {}

public void setParameters(HttpServletRequest request)
{
userID = request.getParameter("userID");
password = request.getParameter("password");
}

public ActionErrors validate() {

if (!userID.equals(password)) {
ActionErrors ae = new ActionErrors();
ae.add("userID", new
ActionError("error.invalid.logon"));
return ae;
}

if (userID.equals("admin")) {
userType = "Adminstrator";
} else
if (userID.equals("user")) {
userType = "User";
} else {
ActionErrors ae = new ActionErrors();
ae.add("userID", new
ActionError("error.invalid.logon"));
return ae;
}

return null;
}

public String getUserType() {
return userType;
}

public void setUserType(String userType) {
this.userType = userType;
}
}

Jimmy, thanks for your reminder and sorry for my
stupid question.  I worked late last night (after
mid-night) and was not thinking well.

Now, I put the struts.jar file back to the CLASSPATH
(not $TOMCATHOME/webapps\MyApplication\WEB-INF\lib)
and everything works.

Error Using select tag To Create Drop-Down Menu


2003-07-21

Thread
Caroline Jen

I am doing testings step by step. I simply want to add
a drop-down menu feature to something that works OKay.
I am a newbie to struts. I do not know where to look
for my mistakes when I encounter problems. 
Something is wrong in my .jsp page. This .jsp page had
worked fine before ...
tags were added. The error message is:


code:
--

2003-07-21 01:24:51
StandardWrapperValve[action]:Servlet.service() for
servlet action threw
exceptionorg.apache.jasper.JasperException: Cannot
find bean under name
org.apache.struts.taglib.html.BEAN

---

Here is the source code of my MainMenu.jsp:


code:
---

<%@ taglib uri="/WEB-INF/struts-html.tld"
prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld"
prefix="bean" %>







 
:


State: 

   
  




---


In the LogonBean.java, I inserted in the
setParameters() method the following code:


code:
---

public void setParameters( HttpServletRequest request
){   userID = request.getParameter("userID");  
password = request.getParameter("password");  
ArrayList states = new ArrayList();   states.add(new
LabelValueBean("Virginia", "VA"));   states.add(new
LabelValueBean("Maryland", "MD"));   states.add(new
LabelValueBean("Ohio", "OH"));   states.add(new
LabelValueBean("Rode Island", "RI"));   states.add(new
LabelValueBean("New York", "NY"));  
request.setAttribute("STATES", states);}

--

I would appreciate if anybody could point out my
mistakes.

RE: drop-down list help


2003-07-22

Thread
Caroline Jen

Hi, Rick:

 Take a look at
http://www.reumann.net/do/struts/main

In Lesson II, you'll find an example of how to use the
html:select tag

Lesson II-4 Create ActionForm - The UI element for
entering a value into the department field will be a
drop-down list.

Lesson II-6 Create DepartmentBean - This bean will be
used to represent options for the drop-down list.

Lesson II-8 Create EmployerService - shows how the
list of departments is created. 

Lesson II-9 Create SetUpEmployerAction - this is where
the list of options is put into the session context.


code:
--

  Collection departments = service.getDepartments();
  HttpSession session = request.getSession();
  session.setAttribute( "departments", departments );

--

Lesson II-14 Create employeeForm.jsp - shows how the
html:select and html:options is used to present a
drop-down list of departments. 

Note the property and labelProperty attributes in the
html:options tag: both id and description are
properties of the DepartmentBean created in II-6. The 
collection attribute is the name "departments" which
was used when the list of DepartmentBeans was added to
the session context (II-9).

ActionForm Design Question


2003-08-01

Thread
Caroline Jen

Hi, I am building a web site.  The primary functions
of this site are for authors to submit their research
papers.  The research papers will go through a
screening process (screened by peers in the field). 
Visiors can view the published articles online.

Authors and peers are the registered users of the web
site.

Therefore, there is not much data manipulation at the
web site except that authors may be requested to
revise their papers and re-submit.  And both authors
and peers have to fill out registration forms to
become members of the web site.

The content of the registration form is pretty
standard: name, address, phone number, academic
background information and achievements, etc.  Most of
them are Strings.  A couple of checkboxes, three sets
of radio buttons (to indicate preferences), and a
primitive double.  Of course, I have a text field for
loading research papers.

Question 1: Do I use conventional ActionForm?
Map-backed ActionForm? or DynaActionForm for this
project?

Question 2: Which strategy should I use to transfer
values between tiers?  Setting an immutable value
object?  or transferring values by reflection
(BeanUtil)? or passing a Map?

I highly value your opinions and advices.  Thanks.

Need Instructions To Setup The Artimus Example

Thread
Caroline Jen

Hi, I am new to Struts.  I would like to get a "look
and feel" of the Artimus example (artimus_1_1.war) in
the "Struts in Action" provided by Husted.

I have the Tomcat 4.1.18 installed and functioning in
my machine.  I also have downloaded the Ant.

Where can I find instructions to quickly deploy the
Artimus example to see all the features offered, such
as users can add, edit, or delete articles,  Any
visitor to the site can view the articles online using
various search features, including full text and by
author, title, or time span?

Thank you very much.

I tried to deploy the artimus_1_1 application and I
followed the instructions in the README file that was
bundled with the artimus_1_1.war.

I successfully logged into the application, using the
username: artimus and password: g0rd0n. 

I continued to followed the instructions.  I  selected
"Create Resources" from the Manager's Options, and
press GO. At this point, I got the following message
on the top of the screen:

The process did not complete. Details should follow. 
ERROR: java.lang.NullPointerException

Please advise me what to do with it.  Thanks a lot.

Confused by index.jsp, welcome.jsp, and logon.jsp


2003-09-09

Thread
Caroline Jen

Hi, I am new to Struts.  I have read the logon example
presented in Husted's "Struts in Action" and deployed
the logon.war on my machine.  Everything works exactly
like what says in the book.

However, I am confused -- 
My question is why I entered
http://localhost:8080/logon
and the welcome.jsp is invoked and displayed in the
browser?

In my mind, http://localhost:8080/logon tells to look
for logon.do.  According to the action mappings:



the Logon.jsp should be invoked.  Could anybody shed
some light on it?

I can understand if I enter
http://localhost:8080/logon/index.jsp
the welcome.jsp is invoked because the logic.forward
tag in the index.jsp: 

<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

NullPointerException While Deploying the Artimus_1_1


2003-09-09

Thread
Caroline Jen

I have 
 
 1. Tomcat 4.1.18-LE-jdk14 up and running in the
Windows XP Pro environment;
 2. I am using Struts-1.1-rc2; 
 3. I have MySQL installed in my machine. And I have
used the Tomcat connection pool to retrieve data
from the MySQL database before.

I tried to deploy the artimus_1_1 application and I
followed the instructions in the README file that was
bundled with the artimus_1_1.war:

 4. I have jdbc2_0-stdext.jar, jta-spec1_0_1.jar, and 

xerces.jar in my 
C:\jakarta-tomcat-4.1.18-LE-jdk14\common\lib
folder

   I hope that jta-spec1_0_1.jar is equivalent to 
   jta.jar
 5. I did not fully understand this instruction:

   "Create a /var/lucene/artimus folder"; therefore,  

   in my machine, I have both folders created
   C:\var\lucene\artimus 
   and 
  
C:\jakarta-tomcat-4.1.18-LE-jdk14\var\lucene\artimus

 6. I exactly followed the rest of the instructions in

the README.txt 

I successfully logged into the application, using the
username: artimus and password: g0rd0n. 

I continued to followed the instructions.  I  selected
"Create Resources" from the Manager's Options, and
press GO. At this point, I got the following message
on the top of the screen:

The process did not complete. Details should follow. 
ERROR: java.lang.NullPointerException

Please advise me what to do with it.  Thanks a lot

Shown below is what in the Tomcat log:

Menu Forwards?


2003-09-11

Thread
Caroline Jen

This is the application I am studying.  The index.jsp
of the application contains two lines:


<%@ taglib uri="/tags/struts-logic" prefix="logic" %>



What is the meaning of this redirect forward?  Is the
browser asked to submit a new request to the path with
logical name "welcome"?

I then searched the config.xml file, 


  


 



 

 

 

 ...

  

The path of the logical name "welcome" is "do/Menu". 
However, there is no Menu ActionServlet in the
application.  

There is Menu.jsp in the application.  Does this
application displays the Menu.jsp file when first
deployed?

Please Help Me To Understand "forward"


2003-09-12

Thread
Caroline Jen

I am studying the code in Artimus_1_1 to make sure
that I understand how things actually work.  I am lost
at the beginning of the application.  Please kindly
help me.  The index.jsp of the application contains
two lines:

code:
--

<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


---

Does this redirect forward tells the browser to submit
a new request to the path with logical name "welcome"?

I then searched the config.xml file, 


code:
---



 

 
 
 
 ...


---

The path of the logical name "welcome" is "do/Menu"
(note it is upper case Menu).  The other place that
"do/Menu" appears in the config.xml is:


   



There is no Menu ActionServlet in the application.

There is a menu.jsp (note it is lower case menu) file
in the application. Does this application display
menu.jsp when it is first launched? Apparently, it
does. This menu.jsp is in the
artimus_1_1/WEB-INF/src/pages/article/content folder.
I am confused - does /do/Menu locate the menu.jsp 

1. in the /src/pages/article/content folder?
2. regardless upper or lower cases?

Confused - Scaffold and Action Mapping


2003-09-17

Thread
Caroline Jen

I have problem to understand the action mapping shown
below:

code:
-

 


 

-

It looks to me that 

1. menuForm is the logical name for the form bean as 
   given in the form-bean segment of the 
   struts-config.xml file.  

Question 1: What is the rational of having 'menuForm'
in the org.apache.struts.scaffold folder in
ActionMapping? 

2. the action that is going to be executed is 
   the ExistsAttributeAction in the 
   org.apache.struts.scaffold folder.  If the 
   condition returned in that action is 'success', the

   article.Menu tile will render the next page. 

   The code of ExistsAttributeAction.java shows:

   mapping.findForward(Tokens.SUCCESS);

Question 2: Where can I find Tokens.SUCCESS maps to
'success'?

Thank you for your help.

Do Not Understand "/tags/struts-logic" not found


2003-09-19

Thread
Caroline Jen

I double checked that 

1. struts-logic.tld is in the 
C:\jakarta-tomcat-4.1.18-LE-jdk14\webapps\MyApplication\WEB-INF\lib
folder

2. in my web.xml file, I have  

/tags/struts-logic
   
/WEB-INF/lib/struts-logic.tld
  

3. in my .jsp files, I have
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

When I ran the application, I had

org.apache.jasper.JasperException: File
"/tags/struts-logic" not found 

displayed in the browser.

I looked at the tomcat log file, it seems to say
something else is going on.  I do not have the ability
diagnose the proble and hereby post the problem for
help.  The log message is in the attachment.  Thank
you.

I am following Ted Husted's example code and setup;
therefore, I do not think it is the problem.  Those

No Error Message But A Blank Page Is Displayed.


2003-09-29

Thread
Caroline Jen

I am experimenting a basic application - logon.  I got
the first two screens working without problem. 
However, the third screen displays a blank page (no
error message).  I am having a very difficult time to
figure out the problem; henceforth, seeking help. 
Here is the history of my application:

1. http://localhost:8080/LogonPractice/index.jsp (no
problem and I clicked on "Sign in")
2.
http://localhost:8080/LogonPractice/Logon.do;jsessionid=170B50E4D8E07EE36290E98342E8BF9C
(no problem and the screen asked for username and
password.  I filled out the information and clicked on
"Submit")  
3. http://localhost:8080/LogonPractice/LogonSubmit.do
(displayed a blank page)

The Tomcat log file shows the following (no error
message at all):

Re: No Error Message But A Blank Page Is Displayed.


2003-09-29

Thread

My welcome page "is displayed" as the very first
screen without any problem.  The page has
 and  tags, which
test if any registered user has logged on.  

The problem occurred after I filled out username, and
clicked the "Submit" button.  Thereafter, the welcome
page was not shown.  My welcome page looks like the
following:

Welcome.jsp

<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Welcome!




Welcome !


Welcome World!

RE: No Error Message But A Blank Page Is Displayed.

I am very grateful for the overwhelming help that I
have received.  

I followed the advices given by all of you and paid
special attention to possible mis-spelling in forward
mapping.  I did not find any mis-spelling or mixing up
of lower case/upper case.

Finally, I re-typed all the key words in the forward
mapping parts of the program.  Everything worked -  I
got the expected page displayed in the browser.

I still do not have any idea why I got a blank page
last night.  I would be more than happy to share my
experience with all of you if I knew the root cause of
the problem.  But, I do not know.

How To Use Connection Pooling in Struts 1.1?


2003-09-30

Thread
Caroline Jen

Before I started converting my web app to STRUTS, I
used a DataSource to do connection pooling. I had the
Tomcat server.xml file configured. My servlet accessed
a helper class in which I had Context.lookup for the
JNDI name.  All worked well.

Now that I am using STRUTS. I try to authenticate the
logon information against "database".  Should I keep
Connection, ResultSet, Statement in an Action or in a
business bean?  How should I utilize a DataSource and
Connection Pooling in STRUTS 1.1?

Re: My Mail is Bombing

Thread

Todd,

 I am uncertain if this piece of information will
be of any use to you -- when I first tried to setup
JavaMail, I followed the online instruction and put
the mail.jar and activation.jar in my
j2sdk1.4.1_02\jre\li\ext folder.  The JavaMail did not
work.  Thereafter, I got an advise from someone saying
that it was a class loader problem.  I then put the
location of the mail.jar and activation.jar explicitly
in the CLASSPATH.  It worked well.

Container-Managed Authentication  in web.xml vs. Specifying Paths in the struts-config.xml


2003-10-06

Thread
Caroline Jen

I use the Tomcat.  I configured the Tomcat JDBCRealm
so that I can use programmic security testing, such as
isUserInRole(), in my program.

Because Tomcat JDBCRealm is form based, I inserted the
 and its sub-elements in my web.xml file
(see below).  As we know, the  and
 are required.

My question is that the container-managed
authentication does not seem to be consistent with
what we usually do in struts; e.g. we state the
logical name and path for each .jsp page in the
struts-config.xml file.  

What is the Struts convention in dealing with user
authentication?  Should we specify the paths for the
logon page and error page in the struts.config.xml or
we should use the  and
 in the web.xml file?

People answer questions without reading my original
post.  Therefore, I must re-type my original question
again.

Before I posted my question, I had configured the
Tomcat JDBCRealm following the instructions at
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/realm-howto.html
so that I can do security testing programmically, such
as isUserInRole(), in my program.

If I use form based authentication, I insert the
 and its sub-elements in my web.xml file
(see below).  As we know, the  and
 are required.

My question is that the container-managed
authentication (we provide login page and error page
in the web.xml) does not seem to be consistent with
what we usually do in struts; e.g. we state the
logical name and path for each .jsp page in the
struts-config.xml file.  

What is the Struts convention in dealing with user
authentication?  Should we specify the paths for the
logon page and error page in the struts.config.xml or
we should use the  and
 in the web.xml file?

HTTP Status 404 After Inserting  In The web.xml


2003-10-10

Thread
Caroline Jen

I think this is more of a problem in the area of
Servlets/JSPs.  Nonetheless, it happened when I ran my
Struts application and I decided to give a try at this
forum.

My application worked well with 


 FORM
  
  
/signin/logon.jsp
  
/signin/logon.jsp?error=true
  
 

in the web.xml file. Thereafter,I inserted
 preceding the 
element, and inserted  following the
 element. The application stopped
functioning.  I got:

HTTP Status 404 -/PracticeVersion
description: The requested resource(/PracticeVersion)
is not availabe.

in the browser, and I have this message in the Tomcat
log file:

LifecycleException: Container
StandardContext[/PracticeVersion] has not been started

This was what my web.xml looked like when the problem
happened:

How To Work Out This Action Mapping?


2003-10-10

Thread
Caroline Jen

Because there is such a statement (shown below) in my
signinForm.jsp:



I put 

 

in my struts-config.xml file.

When I ran the application, I got:

[ServletException in:/article/content/signinForm.jsp]
Cannot retrieve mapping for action /j_security_check' 

I know that I did not specify the action properly. 
What is the correct way to do it?

Thank you for your reply.  I am using container
managed authentication.

My problem is "how to go from j_security_check back to
my Struts framework."

I have my Tomcat JDBCRealm configured and users,
user_roles tables prepared in the database.

In my struts-config.xml file, I did this forward when
users click on the LOGON button:

 

and in my web.xml file, I have:


 FORM 
  
  /signin/logon.jsp
 
 
/signin/logon.jsp?error=true
   


The Tomcat server found the signinForm.jsp through the
/signin/logon.jsp without problem.

and my signinForm.jsp is correctly prepared:

<%@ taglib uri="/tags/struts-html" prefix="html" %>

Re: How To Work Out This Action Mapping?

Thread
Caroline Jen

Thank you very much for the detailed explanation. 
Yet, I still have hard time to make my application
work -- I am "able" to display the welcome page (no
problem). And I have
http://localhost:8080/PracticeVersion/do/Menu;jsessionid=0A6E76A8F3E849BC8DAAC45BFB72F72E
in the address bar.

However, after I click on the LOGON button in the
welcome page, the welcome page remains in the browser.
 The logon.jsp, which collects j-username, j_passwor,
does not get displayed and
http://localhost:8080/PracticeVersion/do/admin/Menu
shows in the address bar.

I do not know what went wrong.  Could it be that the
JDBCRealm is not configured correctly?

Because the LOGON button links to a forward: 
LOGON
 
and in my struts-config.xml, I have 

 

The /do/admin/Menu is my protected resources.  I keep
it unchanged.

1. I configured the Tomcat JDBCRealm and prepared the
users table, user-roles table according the
instructions found at
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/realm-howto.html

2. Because I want to use FORM based container managed
authentication, I inserted 


 FORM 
   
  
/signin/logon.jsp  
  
/signin/logon.jsp?error=true



in the web.xml file.

3. I put logon.jsp in the ApplicationRoot/signin
folder.  Here is the code of the logon.jsp (I took out
all the Struts tags) and I know the code works well
because I have tested it:

Craig, thank you for your very strong support in the
past day or two to guide me through problems with the
container-managed authentication.

I looked at my web.xml file again and again.  There is
nothing wrong with the order of the elements in that
file.  And there is no stack trace in the log files
that talks about an XML parsing error.

I did some experiments.  I found that as long as I
have the JDBCRealm in the
$TOMCAT_HOME/conf/server.xml, the Tomcat does not
accept  element in the
application's web.xml file.  And the Tomcat gives me
"the required resouce /MyApplication is not availabel"
HTTP Status 404. 

Have you seen this kind of problem before?  I have
posted the question at the tomcat-user discussion
forum.

Where Do I Create Session, Set Attributes in Struts?


2003-10-16

Thread
Caroline Jen

I use container-managed form-based authentication to
verify users (it works well).  

Now, I want to create a session and set user's name
after users successfully log in:

HttpSession session = request.getSession( true );
if ( session.isNew() ) 
{
   student.setName(request.getParameter("username"));
   session.setAttribute("student", student);
   Student stud =
(Student)session.getAttribute("student");
}

First of all, in the context of container managed
authentication, can I write:
 
   student.setName(request.getParameter("username"));

Second, what is the proper place to insert the
aforementioned codes.  

The container intercepts and takes care of the
authentication when

 

and the action controller is in the scaffold folder:






where .article.Menu is a tile.

2003-10-17

Thread
Caroline Jen

I have all the required jar files in the
MyApp/WEB-INF/lib directory.  Please help me in
identifying the problems with compilation:

1. For example, I have the commons-scaffold.jar in my
$TOMCAT_HOME/webapps/MyApp/WEB-INF/lib folder.

2. I have the struts.jar in the
j2sdk1.4.1_02/jre/lib/ext folder

3. in my java class, I
import org.apache.commons.scaffold.text.ConvertUtils;
import
org.apache.commons.scaffold.util.ProcessBeanBase;
import org.apache.commons.scaffold.lang.Tokens;

But, I get compilation error:

package org.apache.commons.scaffold.text does not
exist

package org.apache.commons.scaffold.util does not
exist

I have to prepare many drop down lists for visitors of
the website to make selections.  For example, I have

Java Compiler Cannot Find the Required JAR File in the Classpath


2003-10-20

Thread
Caroline Jen

I posted this problem before.  Max and Carey answered
my post right away.  I tried and tried   I must be
missing something.

I really do not understand why all of a sudden that
the java compiler cannot find the required JARs in the
classpath.  I have done some similar compilation
before successfully.  My head is not sober enough to
pinpoint the problem this time.  

I am doing the compilation manually (I am not using
ANT or any IDE).

1. I have the commons-scaffold.jar in my
$TOMCAT_HOME/webapps/PracticeVersion/WEB-INF/lib
folder.

2. I have the struts.jar in both
$TOMCAT_HOME/webapps/PracticeVersion/WEB-INF/lib
folder and j2sdk1.4.1_02/jre/lib/ext folder

3. in my java program (Bean.java), I
import org.apache.commons.scaffold.text.ConvertUtils;
import
org.apache.commons.scaffold.util.ProcessBeanBase;
import org.apache.commons.scaffold.lang.Tokens;

4. I first set the classpath 
C:\>set
CLASSPATH=C:\jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/src/java;%CLASSPATH%

then, I go to the folder where Bean.java is

C:\>cd
jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/src/java/org/apache/artimus/article

then, I try to compile and put the class file in the
destination folder

C:\jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/src/java/org/apache/artimus/article>javac
-d
C:\jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/classes
Bean.java

But, I get compilation error:

package org.apache.commons.scaffold.text does not
exist
package org.apache.commons.scaffold.util does not
exist
package org.apache.commons.scaffold.lang does not
exist

Re: User Authentication implemented in Struts


2003-10-22

Thread
Caroline Jen

My question is similar.  I use container-managed
"role"-based security checking.  I put "role" property
in Action Mapping and use isUserInRole in my JSPs. 
For example, John can view the sales reports if he has
the "sales role". Now, I want to further restrict John
to view the sales reports in is "region" only.

People say that I can use the servlet filter. I need
guidance to see some examples.

To the Person Asked About Form-Based Container-Managed (JDBCRealm) Authentication Question


2003-10-23

Thread
Caroline Jen

Hi, I saw your message asking me about the form-based
container-managed authentication in Struts.  I
accidentally deleted your message and could not find
your name and e-mail address.

The following steps are what should be done:

1. configure the JDBCRealm in the Tomcat server.xml,
see
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/realm-howto.html

2. container-managed, form-based authentication is
completely handled by the server.  That is to say, it
is none of Struts business.  Prepare your logon.jsp
and error.jsp (do not use Struts tags).  There is
nothing wrong with your j_security_check, ..., etc.

3. in your web.xml, you have

  
FORM 
 
 
/signin/logon.jsp  
 
/signin/error.jsp
  
   

4. Do not change your action forward in the
struts-config.xml file (i.e. do not forward anything
to logon.jsp because it has nothing to do with Struts)
except add redirect="true".  For example:

 

Craig McClanahan wrote a detailed explanation on how
it works (I am quoting what Craig said below):

form-based login is triggered the first time that an
unauthenticated user requests a URL that is protected
by a security constraint.
(1) Unauthenticated user requests a protected resource
(*NOT* the login page!) 
(2) Container remembers the protected resource that
was requested in a private variable. 
(3) Container displays the login page, which must have
a destination of "j_security_check", and waits for the
user submit. For some containers, including Tomcat,
this is the one-and-only time that submitting to
"j_security_check" will not return a 404. 
(4) User enters username and password, and presses the
submit button.
(5) the post to j_security_check is intercepted by
your servlet container, which performs Container
Managed Authentication - it looks for the j_username
and j_password, authenticates the combination, and
forwards to the originally requested resource, or to a
configurable error page if the authentication 
(6) Container authenticates the username (j_username)
and password (j_password) combination. If valid,
container recalls the originally requested resource
saved in (2) and displays *that* to the user in
response to the login submit.  Or forwards to a
configurable error page if the authentication fails.
The important point is that, at no time, did anyone
ever submit a request to the URL of the login page,
because there is no such thing.  Also think of the
login page as part of the container, not part of your
app. 


Let me know if you have further questions.

-Caroline

Tiles And Images

Thread

I use tiles and stylesheet to display my web pages.  I
also try to insert some images in those pages.

The tiles work fine.  I have header, footer, navbar,
content, etc. displayed without problem.  But, I am
curious to know if anybody has had difficulties in
inserting images.  I have tried various ways and
cannot succeed.

Tile and html:img


2003-10-24

Thread
Caroline Jen

Thanks for the advices that have been given to my
earlier question regarding inserting images while
using tiles.  

The tiles part works fine.  The browser still has
problem to pick up the image that I try to insert. 
This is what I do:

1. I have  inside the  tage in the
main JSP page.

2. I use the following code in the header.jsp





3. The header.jsp is in the
ApplicationRoot/article/common folder

4. The images folder is where the header.jsp is; i.e.,
in the 
ApplicationRoot/article/common folder

5. I checked the spelling; including upper/lower
cases, of the path and the name of the image.  I also
checked the extension of the image.

I sort of think it is the path problem.  Please
comment on what I did.  Thank you.

My logic Tag Does Not Seem To Work


2003-10-27

Thread
Caroline Jen

Please point out my mistakes.  Does the 'name'
attribute of the logic tag accept an object only?  For
example, I created a session this way:

HttpSession session = request.getSession();
String username = request.getRemoteUser();
session.setAttribute( "user", username );

In the LogoffAction, I invalidate the session and want
to forward the visitor to the welcome page.  This is
what I did:

HttpSession session = request.getSession(false);
String username = (String)session.getAttribute( "user"
);
if (username != null) 
{
   session.removeAttribute( "user" );
   session.invalidate();
   return (mapping.findForward( "success" ));
}

I used the logic tag in my welcome.jsp.  It does seem
to work because the LOGOFF button is still displayed.

RE: Forward Cannot Be Achieved In One Step


2003-10-28

Thread
Caroline Jen

Let me re-phrase my question.

Upon the user click on the LOGOUT buttion, I have two
actions - the first one of the actions is Logoff.java
in which I invalidate the session, ..., etc. and the
second action upon success will lead the user to the
welcome page in which choices for unregistered member
plus a LOGON buttion is provided.
 
As long as two actions are involved, the user does not
get back to the welcome page by just click on the
LOGOFF button "only once". 

Need your guidance on how such a situation is usually
handled?

RE: Forward Cannot Be Achieved In One Step

Thread

I have tried your suggestion.  It still takes two
steps to go back to the welcome page.  

As long as there are two actions in between, it does
not seem that I can go directly from "clicking the
LOGOUT buttion" to "have the welcome page displayed".

I really wish to learn what people usually do - the
first one of those two actions is Logoff.java in which
I invalidate the session, ..., etc. and the second
action upon success will lead the user to the welcome
page in which choices available for unregistered
members plus a LOGON buttion are provided.

I have checked the syntax of the isUserInRole in the
request.tld, which is:

 
<%-- do something --%>


Is it possible to specify more than one role?  What is
the syntax of specifying that?  My application has
many roles.  In some cases, both "administrator" and
say, "contributor" share doing the same thing.

How To Submit A Propery/Value Pair That Is Not Selected/Filled-Out By Visitors of the Website?


2003-10-30

Thread
Caroline Jen

In the welcome page, all visitors of the web site can
choose to view any article that is available in the
database.  But, visitors will not be able to delete or
update any of those articles (DELETE, UPDATE, etc.
buttons are not provided).  This part of my struts
application works well.  I have a drop-down list
enclosed in  for visitors to make a
selection and submit it for an action to be taken:



Find articles by: 







GO

 

Visitor can choose articles by title, author,
category, content, or article ID.  If "author" is
selected from the drop-down list and the name of the
author "Victor Hugo" is supplied, keyName will be set
as creator and keyValue will be set as Victor Hugo for
further processing as shown in my struts-config.xml
below:










After a registered visitor successfully logs in, a
user specific page is displayed.  For example, after
the author Victor Hugo who has submitted several of
his articles at the web site logs in, he will see a
page with "Submit Article" and "View Article" (IT IS A
LINK OR A BUTTON.  IT IS NOT A DROP DOWN LIST), etc. 
The author can view his own articles only because
DELETE, UPDATE, etc. buttons will be provided.

I am stuck here.  There is no drop-down list for
Victor Hugo.  How do I supply keyName (which is
"creator") and keyValue (request.getRemoteUser) to the
action below if Victor Hugo clicks on the "View
Article" button?

findByProperty() in the scaffold.sql.AccessBase - Need One Additional Parameter to the Pair of Property/Value


2003-10-30

Thread
Caroline Jen

I am using the findByProperty method in the
org.apache.commons.scaffold.sql.AccessBase.  The
findByProperty method takes "one" pair of
property/value as it parameters.  As such, visitors of
the web site can query all articles in the database by
providing 'author' as the property and supply the name
of the author (xyz) as value.

public static final Collection findByProperty
(
Object target,
String property,
String value
) throws ParameterException, PopulateException,
ResourceException

I have this field "category" in my database.  I want
to search and get all the articles written by
author(property) with name xyz (value) within the
HISTORY category.  The value of the category will be
supplied by the application developer (NOT BY THE
VISITOR of the web site via selecting from a drop-down
list and fill out the value in the text field).

I need help in handling this kind of situation. 
Thanks in advance.

I am trying to modify the behavior of the

I put the struts.jar and struts-scaffold.jar in my

Hidden Field

works well because "author" is expected literally as
the value of a property called "dispatch".

I also want to pass 
String username = request.getRemoteUser(); 
as the value of a property called "keyValue".

But,

or


gives me problems.  What is the proper way of doing it?

Session Times Out


2003-11-02

Thread
Caroline Jen

I check if session expires for each action in the
application.  If the session times out, I forward the
user to index.jsp so that the user can log on again.  

How do I inform the user with a message that he/she is
at the welcome page because the session has expired?

RE: Handling Session Timeout


2003-11-05

Thread
Caroline Jen

People have suggested servlet filter is a good choice
to check session time-out that if I want all servlets
and JSPs remain intact.

I do not have any idea how it works in Struts.  First
of all, I think this servlet filter has to be declared
in the web.xml.  I have many actions in the struts
application.  How do I call this servlet filter
whenever the flow goes to an action?  Do I code 

HttpSession session = request.getSession( false );
if ( session != null) 
{
   session.removeAttribut( ... );
   session.invalidate();
}

in the doFilter(); ?

FAQ (Passing Variables Between Actions); But, Stuck and Need Help


2003-11-06

Thread
Caroline Jen

Passing variables from one action to another is a
frequently asked question.  The answer is to use
either hidden fields or a session object.  

The story starts with searching the database.  My
application offers options to search the database by
author, title of the article, article ID, or . I
have a drop-down list in my JSP for visitors to make a
selection.  By clicking on one of those options, the
property "dispatch" is set.  And the visitor fills out
the text field to set "keyValue".  With both
"dispatch" and keyValue forwarded to an "action"; say,
Action ONE, the desired articles can be retrieved from
the database.  So far so good.

What I have handled next is the "author's page" of the
web site.  An author can only view his own articles
and perform update, delete, save, ... functions.  I
use the hidden field technique to handle it.  The
property "dispatch" is arbitrarily set as "author"
(needless to say) and keyValue can be obtained by

String username = request.getRemoteUser();

And,




are forwarded to the same action (Action ONE) for
processing.  Again, no problem.

Now, the application has another user case -  editors.
 An editor only retrieve and view all articles in
his/her own field of specialization.  I arbitrarily
set "dispatch" as "field_of_specialization" and use
the hidden field technique:



Nonetheless, the way to get the "value" the editor's
field of specialization is from the database.  Because
editors are registered members of the web site, the
application should be able to look for his/her profile
and obtain his/her field of specialization in the
database once an editor successfully logs into the web
site.  Therefore, it takes an "action" (Action TWO)
that tells the business tier to find the "keyValue" in
the database.  And should I put the "keyValue" in a
session object.  

I have tried to handle this situation again and again
in many different ways.  I am very frustrated and need
help -- how does a user go from by clicking a button
in a JSP to go to Action TWO (get the keyValue) and
then forward this keyValue and 


 
to Action ONE for retrieving the desired articles from
the database?

Re: FAQ (Passing Variables Between Actions); But, Stuck and Need Help

Thread
Caroline Jen

Thank you for the very useful and constructive
feedbacks.

I think I am going for the first method that you
suggested - create a user bean and store it in a 
session object at login.  My concern is that I use
container managed authentication at login.  After the
container does its job, is there any way other than
using an Action that delegates the business tier to
search the database and obtain the value of
field_of_specialization?  If an action has to be
involved at this point to form a session object, does
it suffer the the disadvantage of being overwritten if
the user has more than one browser window opened?

In regard to the two-action approach that you
discussed toward the end of your message, I
encountered some problems.  If you would take a look
at the problem -  I provide a buttion in editor's
page, which is a JSP tile:



View Articles



If the button is clicked, I attempt to use an Action
(via the path /editor/Category) to search the database
for the field_of_specialization.  However, I got this
message in the browser:

[ServletException in:/article/content/menu.jsp] Cannot
retrieve mapping for action /do/editor/Category'

and in my struts-config.xml

Off Topic, Problem With Passing Business Bean in Between Classes As Part of My Struts Application


2003-11-27

Thread
Caroline Jen

It is not a Struts problem.  But, it is the problem I
encounter in my Struts application.  Please help.  I
am NOT showing all my code.  For example, I skip the
DAO interface, and the class that returns a connection
object from the connection pool.  Nonetheless, those
classes are irrelevant to my question.

The root of my problem is that I do not know how to
pass data that are wrapped in a business bean in
between classes.  THE JAVA COMPILER DOES NOT RECOGNIZE
THE BUSINESS BEAN!

1. I have a controller Servlet that reads the
"username" that is supplied by a visitor of the web
site. I want to search the database by the "username"
and get some information about that user; such as
userrole, category, etc. A business bean sits in
between the controller servlet and the database. Here
is the partial code of the controller servlet:
[code]
// the statement below has problems
EditorBean editorData;
// Obtain username and password from web tier
String username = request.getParameter( username );
// find the editor's information via the business tier

// Again, the parameters that I supplied in the method
below have problems
EditorBean editor = EditorBean.findEditorData(
username, editorData );
// wrap the information found in the database in a
session object and go on
HttpSession session = request.getSession();
editor.setUserrole( request.getParameter( "userrole" )
);
editor.setCategory( request.getParameter( "category" )
);
session.setAttribute( "editor", editor );
[/code]
2. I have this EditorBean class. This EditorBean is a
business bean. I am struggling with how the EditorBean
pass the data in between the controller and the
database.
[code]
import org.apache.artimus.logon.dao.*;
public class EditorBean 
{   
   private String username;
   private String userrole;
   private String category;
   EditorDAO ed = new MySQLEditorDAO();
   public EditorBean() {}
   public EditorBean( String username, String
userrole, String category )
   {
  setUsername( username );
  setUserrole( userrole );
  setCategory( category );
   }
   public String getUsername(){ return username; }
   public void setUsername( String username ) {
this.username = username; }
   public String getUserrole(){ return userrole; }
   public void setUserrole( String userrole ) {
this.userrole = userrole; }
   public String getcategory(){ return category; }
   public void setCategory( String category ) {
this.category = category; }
   // the parameters in the method below have problems
   public EditorBean findEditorData( String username,
EditorBean editorData )
   {
  // What do I do here?
  ed.findEditor( String username, ?? );
  // I am not sure what to return here
  return ?;
   }
}
[/code]
3. Here is my data access class:
[code]
import java.io.IOException;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.SQLException;
import
org.apache.artimus.logon.exceptions.EditorDAOSysException;
import org.apache.artimus.ConnectionPool.DBConnection;

public class MySQLEditorDAO implements EditorDAO{
   // the parameters of the method below have problems
   public EditorBean findEditor( String username,
?? )
throws EditorDAOSysException
   {
  Connection conn = null;
  Statement stmt = null;
  ResultSet rs = null;
  try
  {
 conn = DBConnection.getDBConnection();
 stmt = conn.createStatement();
 String query = "SELECT user_role,
journal_category FROM members WHERE user_name = '" +
username + "'";
 rs = stmt.executeQuery( query );
 if (rs.next())
 {
// something is wrong in returning the
information about that editor
return new EditorBean( username,
rs.getString( "user_role" ), rs.getString(
"journal_category") );
 }
 else
 {
System.out.println( "invalid user name" );
return null;
 }
  }
  catch (SQLException se)
  {
 throw new
EditorDAOSysException("SQLException: " +
se.getMessage());
  }
  finally
  {
 if ( conn != null )
 {
try
{
   rs.close();
   rs = null;
   stmt.close();
   stmt = null;
   conn.close();
}
catch( SQLException sqlEx )
{
   System.out.println( "Problem occurs
while closing " + sqlEx );
}
conn = null;
 }
  }
   }
}
[/code]

re: Getting ArrayList of objects from my form bean into my drop down list -> solution

What a good timing to see this post.  I was about to

I have an ArrayList of JavaBean objects created from

while(rs.next())

   editorBean=new
EditorBean(rs.getString("user_name"));
   editors.add(editorBean);
}
   return editors;

Obviously, each EditorBean object is the value of the
"user_name".  If I have this 
request.setAttribute( "EDITORS", editors );

How do I create a drop-down list?  Please comment the
way I tend to code:

How To Display the Information That Is Wrapped In a Session Object


2003-11-28

Thread
Caroline Jen

1. I my action class, I reference a bean 

EditorBean editor = EditorBean.findEditorData(
username );

2. this bean accesses the data access logic and the
bean gets populated by information fetched from the
database (see the code below)

3. In the action class, I then wrap editor in a
session object:

HttpSession session = request.getSession();
editor.setUserrole( request.getParameter( "userrole" )
);
editor.setCategory( request.getParameter( "category" )
);
session.setAttribute( "editor", editor );

4. In the JSP, how do I get userrole and category from
the session object and how to display them in Struts?

Here is my EditorBean class:

public class EditorBean {

   private String username;
   private String userrole;
   private String category;

   // UserDAO and MySQLUserDAO are in another package.
 Must import that package.
   // should not instantiate an interface because it
does not have a constructor
   static EditorDAO ed = new MySQLEditorDAO();

   public EditorBean() {}
   public EditorBean( String username, String
userrole, String category )
   {
  setUsername( username );
  setUserrole( userrole );
  setCategory( category );
   }
   public String getUsername() {
  return username;
   }
   public void setUsername( String username ) {
  this.username = username;
   }
   public String getUserrole() {
  return userrole;
   }
   public void setUserrole( String userrole ) {
  this.userrole = userrole;
   }
   public String getcategory() {
  return category;
   }
   public void setCategory( String category ) {
  this.category = category;
   }
   public static EditorBean findEditorData( String
username ) 
   {
  return ed.findEditor( username );
   }

How Do I Create This Drop-Down List in Struts?


2003-11-29

Thread
Caroline Jen

My ArrayList is a collection of bean object.  The
ArrayList is created this way:

public Collection findEditors( String userrole, String
category ) 
{
   ..
   EditorBean editorBean = null;
   ArrayList editors = new ArrayList();
   // database access code
   while( rs.next() )
   {
  editorBean = new EditorBean(
rs.getString("user_name") );
  editors.add( editorBean );
   }
   return editors;
   ...
}

and my EditorBean is like:

public class EditorBean 
{
   private String name;

   public EditorBean() {}

   public EditorBean( String name )
   {
  this.name = name;
   }
   public String getName() {
  return Name;
   }
   public void setName( String name ) {
  this.name = name;
   }
}

After "editors" is returned, I create a session
object:

session.setAttribute( "EDITORS", editors );

How do I create a drop-down list for this collection
of editors?

Very Troubled in Finding Ways to Pass a Variable to a Class


2003-12-05

Thread
Caroline Jen

I have a class FindEditorData.java.  I want to pass a
vairable 'username' to this class for some processing.
 This class is invoked from a JSP:


View Articles

and the value of the 'username' is obtained this way:

String username = request.getRemoteUser();

Due to my limited knowledge in Struts,  I cannot
figure out what to do.  Let me explain the problem:

1. This class has this method:

   public Object execute() throws Exception { ... }

   I do not make this class extends HttpServlet or
extends Action.  I cannot nest a method inside a
doGet/doPost or the Action's excute().

2. The action mapping in the struts-config.xml is this
way:

   
   

I am stuck because I do not know how to pass
'username' to the FindEditorData.java.  I cannot
state:

   String username = request.getRemoteUser(); 
   or 
   String username = (String)session.getAttribute(
"EditorName" );

   because the FindEditorData is not a servlet and
does not extend Action.

I cannot pass a hidden variable from the JSP because I
do not know how to retrieve the value of a hidden
variable in a Java class.

Need clever ideas.  Please help.

This Java class has a mapping in the struts-config.xml

RE: Very Troubled in Finding Ways to Pass a Variable to a Class


2003-12-06

Thread
Caroline Jen

It is wonderful to know that there are some ActionForm
methods that holds true in the
scaffold.ProcessAction's execute() method.  It gives
the hope that my problem could be resolved.  

Via a submit button in my JSP, I try to pass two
variables; username and keyName, to my Java class
(FindEditorData.java) with the
type="org.apache.struts.scaffold.ProcessAction", and
this Java class has this method:

   public Object execute() throws Exception { ... }

1. if I use the hidden field technique (see below)
inside the JSP  tag:
<% String username = request.getRemoteUser();%>



How do I retrieve the value of username and keyName in
the Java class?  Probably due to my lack of knowledge
of the ActionForm, I got compilation error "cannot
resolve symbol: request" or "cannot resolve symbol:
session" because FindEditorData.java does not extend
HttpServlet and FindEditorData.java does not extend
Action.

2. if I want to get 'username' in the Java class
instead of passing the 'username' as a hidden field
from a submit button in my JSP, how do I do it?

String username = request.getRemoteUser(); gives me a
compilation error "cannot resolve symbol: request".  

The action mapping in my struts-config.xml looks like:

Pass A String From Servlet And Write Out Its Value in JSP


2003-12-07

Thread
Caroline Jen

My servlet has a String called 'category'.  I want to
pass the String to a JSP.  Therefore, I have the code
shown below in the servlet:

session.setAttribute( "c", category );
OR
request.setAttribute( "c", category );

And, I do the following in my JSP:

<% String keyValue = (String)session.getAttribute( "c"
); %>
OR
<% String keyValue = (String)request.getAttribute( "c"
); %>

How do I write out keyValue in my JSP in Struts?

My code was shown in my original message.  I used two 
 tags to pass two hidden fields, one
is successfully passed while the other shows null.  By
the way, I do not use 'request' to retrieve the value
of the hidden field because my Java class is a
scaffold.ProcessAction type.  I simply use getXxx.

Let me show my code again:

Re: HELP: about to get datasource of struts and pass to logic beans...

There are lots of classes involved.  I will give you
an example:

1. my LogonAction calls EditorService.java (business
delegate)
2. EditorService.java calls MySQLEditorDAO.java (data
access object implements EditorDAO.java, which is a
data access interface)
3. the MySQLEditorDAO.java returns EditorBean.java (a
Java bean with three properties)

Here is my LogonAction.java:

package org.apache.artimus.logon;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletResponse;

EditorService service = new EditorService();
EditorBean editor = service.findEditorData(
username );

HttpSession session = request.getSession();
session.setAttribute( "editor", editor );

// Log this event, if appropriate

if (servlet.getDebug() >= Tokens.DEBUG) {
StringBuffer message =
new StringBuffer("LogonAction: User
'");
message.append(username);
message.append("' logged on in session ");
message.append(session.getId());
servlet.log(message.toString());
}

// Return success
return (mapping.findForward(Tokens.VALID));

}

} // End LogonAction

Here is the EditorService.java:

{
   EditorDAO ed = new MySQLEditorDAO();
   public EditorBean findEditorData( String username )

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction

I did not mess up lowercase and uppercase of the
hidden field I want to pass from my JSP to the
scaffold.ProcessAction.  If it had been the
lowercase/uppercase problem, I would have gotten a
message saying that the variable could not be
recognized.  

I pass two hidden fields at the same time.  One of
them is successfully passed with correct value.  The
other is passed but its value shows a 'null' in the
scaffold.ProcessAction.  What could go wrong?  Let me
show my code again:

Two hidden fields: username and keyName are passed 
from a JSP via a SUBMIT button:



<% String username = request.getRemoteUser();%>

and an action mapping:


   


The value of the 'username' is found to be a 'null' in
the FindEditorData.java while the value of keyName is
successfully retrieved.  In the browser, I got:

name=null; kn=journal_category; kv=null 

The code of my FindEditorData is shown below:

I pass two hidden fields: username and keyName at the
same time.  The keyName is passed and with the correct
value in it.  The username is passed but its value
turns out to be a null.

It is impossible for request.getRemoteUser(); in my
JSP returning a null.  (see code below) Before it
reaches request.getRemoteUser(); the user has already
been successfully logged in with a valid name.





<% String username = request.getRemoteUser();%>
