How to do validation with a class that extends DispatchAction?

I'm trying to mess around with some validation with struts for a .jsp form and I've read a tutorial that says I need to extend ValidatorForm instead of ActionForm...however, I'm using DispatchAction instead of ActionForm. What is the best way to do validation if I'm using a DispatchAction?
Thanks a lot.

Hey evnafets,
I do have the struts validator configured in the struts config file, and I do get the following message:
Jun 21, 2005 10:06:55 AM org.apache.struts.validator.ValidatorPlugIn initResources
INFO: Loading validation rules file from '/WEB-INF/validator-rules.xml'
Jun 21, 2005 10:06:55 AM org.apache.struts.validator.ValidatorPlugIn initResources
INFO: Loading validation rules file from '/WEB-INF/validation.xml'
I added the <form-set> tags but am still getting nothing, I'm now wondering if it may have something to do with the following, which I just noticed...
In my .jsp file, I have something like this:
<html:form action="/modifyBook">
<html:errors />
Name: <html:text property="fname" value="${entry.fname}"/> <html:text property="lname" value="${entry.lname}" /> 
<html:hidden property="method" value="edit"/>
<html:submit property="submitValue">Edit</html:submit>
<html:cancel property="cancelValue">Cancel</html:cancel>And in the "edit" method of the ModifyBookAction class, I cast the form into a DynaValidatorForm and just have my code to perform the edit. Now, what I'm wondering is, is the form getting properly associated with a "ModifyBookForm" which is what the rules are written for? The only tie I see is in the struts config where there is this:
 <action
 name="ModifyBookForm"
 parameter="method"
 path="/modifyBook"
 scope="request"
 type="com.yourcompany.struts.action.ModifyBookAction"
 validate="true">
 <forward
 name="failure"
 path="/form/error.jsp"
 redirect="true"/>
 <forward
 name="success"
 path="/loadBook.do"
 redirect="true" />
 </action>Is this enough? I'm thinking that the validation may be set up correctly, I'm just not implementing it in the right way?
Thanks again

Getting grid layout to work with a class that extends JFrame

In my code, I have a class extending JFrame and setting the layout to grid works and the code to add with three parameters compiles just fine but when I run it I get this:
java.lang.IllegalArgumentException: illegal component position
     at java.awt.Container.addImpl(Container.java:999)

     at javax.swing.JFrame.addImpl(JFrame.java:479)
     at java.awt.Container.add(Container.java:928)
on the add(myLabel, 1, 1); line

I see on these from
http://java.sun.com/j2se/1.5.0/docs/api/java/awt/Container.html#add(java.awt.Component)
1.public Component add(Component comp)
2.public Component add(String name, Component comp)
3.public Component add(Component comp, int index)
you should use method add(...) of JPanel instead

How to declare a custome AS-class that extend a Flex componenet

Hello there, would you please help. I have the following mxml tag
<mx:Application xmlns:mx="xmlns:fx="http://ns.adobe.com/mxml/2009"xmlns:custom="com.myComponents.*" layout="absolute" />
<custom:ReturnData id="dataR" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true" />
<fx:Declarations>
<s:CallResponder id="getAllResult"/>
</fx:Declarations>
When I change this into AS and try to use the result in a dataGrid, no info will be populated in datagrid, any idea??? It works when use the xmlns tag.
2) as actionscript object
<fx:Script>
 <![CDATA[
 import com.myComponents.*;
 public var dataR:ReturnData;
 getAllResult.token = dataR.getAll();
 ]]>
</fx:Script>
<mx:DataGrid x="10" y="21" id="dataGrid" creationComplete="dataGrid_creationCompleteHandler(event)" dataProvider="{getAllResult.lastResult}">
<mx:columns>
<mx:DataGridColumn headerText="TreatmentareaID" dataField="TreatmentareaID"/>
<mx:DataGridColumn headerText="ProductName" dataField="ProductName"/>
</mx:columns></mx:DataGrid>I

Thanks for your feedback, my original code is as here below. DataGrid2 populate the data since the component has been initialized in the xmlns. DataGrid does not populate the data and has been initialized by ActionScript???
Any idea where do I do wrong?
Thanks

Hi
I am not suprised no one answered your questions, there are simply to many of them. Can I suggest you read the faq on 'how to get help quickly at - http://forums.adobe.com/thread/470404.

How to call a class that extends a frame from a panel ?

How to call a class that extends a frame from a panel ?
I am trying to create an application say "Videoshow"
Videoshow has a panel which in turn consists of 2 components : 1]a textarea( to show the contents of a page) and 2] a mediaclip(to show the video).
Now I have an application "MediaApplication"(to show the videoclip) which extends Frame (Code from Java 2 Unleashed, Chap 21). I want to show this MediaApplication in Component 2 of the above panel. But when I do this, I only see the MediaApplication frame instead of the whole SlideShow.
I want to do something likethis.
VideoShow :
|---------------------------------|-------------------|
| |
| (Comp 1) | (Comp 2)
| TEXTAREA | Video Clip
| |(MediaApp entends Frame)
|---------------------------------|-------------------|
What is the best way to achieve this ? Also which component can I use to show the videoclip ?

im not familiar with the code you mention from Java 2 Unleashed, but your best bet is to read up on Swing a bit - so you get an idea of how Swing containers and components work - then im sure you'll find a solution to your problems. Then if you encounter any difficulties whilst your attempting to do that, post your code in the Swing forum and im sure someone will help you.

Can any one change this Applet into a class that extends Jpanel.....

Hi,
I need this applet as a class that extends JPanel, I will be very very thankful to you if any one kindly change this Applet code into a class that extends JApplet.

thank you sir for your advice.
Its not like that I without any attempt, just past code here & asked for its conversion. I spent about 5 hours on it, can say spoil whole day but to no avail. You then just guide me, give some hint so that I do it. I will most probably wanted to do it by myself but asked for help when was just disappointed.
I try to put all init() in default constructor of identical copy of this applet that extends JPanel. Problem.....ball tend to fell but pad not moving. Also out out was not getting ant color input. That was like my best effort.....other tried that I found by search like just do nothing only extend panel OR frame in spite of applet, start applet from within main of another class.... these are few I remember what I tried.
I will be very very thankful to you if you can help/guide me how can I do it. Behavior of the Applet is like a normal PONG game with on pad controlled by arrow keys, & one ball colliding with walls of boundary & falling down.
Thanks a lot again for your attention & time.

Portlets development: When to use the class that extends PortletBridge...

When I create some Portlet (.jspx based) JDeveloper generate some resources. One of those is a class (with the name that I´ve configured) that extends PortletBridge...
Ok. So, I want to know if I use JSF standards should I put my actions into this class or should I create another Managed bean to handle that? What to do with this generated class?
Thank you.

So you want to create a portlet that uses JSF instead of JSP?
You can JDev do that for you. When you create a new portlet there is a step where you can specify the default page for the portlet mode (view, edit).
On the right hand side you can select ADF JSF (or something like that).
JDev will then create a class that extends the PortletBridge class and you don't have to do anything more. Just edit the jspx like it's a normal page.

Using the UI editor for a class that extends an abstract class

Hi,
At the moment it's unfortunately impossible to use the UI editor to edit a class that extends a certain abstract class. There is a way to circumvent this problem, by using a proxy class. Does anyone know how to create a proxy class for this purpose and how to register it?
Hopefully a future JDeveloper release will solve this problem. Is this a planned feature?
Regards,
Peter

I hope it works for you now (why using , but not indentation?).

JEditorPane (or subclasses) and a class that extends JPanel

hello to all,
i'm realizing an application with Swing.
i have realized a class that extends JPanel(called "PanelLayer") and, other to draw a ruler as Office 2003, it must contain an other subclass of JPanel (called "PanelLayer") that, in turn, will contain a JEditorPane.
the problem is strange: i should continue in moviment the mouse to look well the JEditorPane (or subclasses)

Don't really understand what the posted code does and I can't execute the code so I don't have much to offer.
But I did notice that you don't invoke super.paintComponent(...) which means you may have garbage being painted on the panels.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)", that demonstrates the incorrect behaviour.

Can I invoke a class that extends JAppl from another class extends JAppl

Can I invoke a class that extends JApplet from another class that extends JApplet. I need to invoke an applet then select an action which opens another applet. Thanks in advance.

Nobody is able to solve this problem, i cant even
think this things. i have hope so plz try and get
result and help.Did you understand what Sharad has said???
Yep, you can forward to specific error page from servlet when even error occured in JSP. In order to achieve you have to open jsp file from servlet say example by using reqdisp.forward.
handle exception in the part where you are forwarding. And forward to the specific error page inside catch block.

Closing a class that extends JPanel

Hi, i have a class that extends JPanel(lets call it class A). In that class, if the user click the logout button, i want class A to close and display class B that extends JFrame. right now, i am able to call class B, but i cannot close class A.
I uses remove() to close class A, but it doesnt work... could u tell me what to do??
I put this code in class A...
if (e.getSource() == logoutButton)     {
     remove(this);
     new Rest_Login1();
     String [] ar = null;
     Rest_Login1.main(ar);
} Thx

some of my code look like this.

import javax.swing.*;
import javax.swing.event.*;
public class CustomerPanel3 extends JPanel implements ActionListener
// some JButton, JLabel n etc

               remove(this);
               new Rest_Login1();
               String [] ar = null;

How do I write a Java Class that Loads a RPT and exports to PDF All Automatically?

I am using Crystal Reports for Eclipse and I am trying to create a java class that will do everything independently. It will take a .rpt file, load it with data from the database and then export that to a pdf file and put that pdf in a specific location with a specific name. I am using the Crystal Reports for Eclipse and the sample jsp project does that but I am looking for a java class example that doesn't require human interaction through the website. I have read the help file and seen snippet examples but I am not seeing a complete example. Could someone point me in the proper direction of a good example either in the forum or the help file for eclipse?

Hi, If you wanted to achieve this in a JSP page then I would suggest using the JSP Page Wizard as it allows you to select PDF as an output type. You can run the wizard and choose the PDF output and it will automatically generate the required code for you. However, as you want to use a Java class then I would suggest downloading the following package of sample code:<a href="http://support.businessobjects.com/communityCS/FilesAndUpdates/crxi_r2_jrc_desktop_samples.zip">http://support.businessobjects.com/communityCS/FilesAndUpdates/crxi_r2_jrc_desktop_samples.zip</a> This package includes a number of sample Java classes that demonstrate how to use the engine. The one that you will be interested in is titled "JRCExportReport" To make life easier I would suggest trying the class in a Crystal Reports Web Project as the runtime libraries will automatically be in the classpath. Anyway, give this a shot and let me know how you make out.

How do I deal with Tokenized strings that are blank?

I'm writing a little application that writes data to a file. It sends data to the file as a "|" delineated string. Then I use tokenizer to break up the string as follows:
try {
                              String searchtext = SearchTxt.getText();
                              String tokenString = "";
                              String[] returnData = new String[8];
                              File filedata = new File("bigbase.txt");
                              BufferedReader in = new BufferedReader(
                              new FileReader(filedata));
                              String line = in.readLine();
                              while ( line != null) {
                              Pattern pat = Pattern.compile(searchtext);
                              Matcher mat = pat.matcher(line);
                                   if ( mat.find() ) {
                                   StringTokenizer t = new StringTokenizer(line, "|");
                                   maintextArea.setText("");
                                   int count = 0;
                                        while (t.hasMoreTokens()) {
                                             tokenString = t.nextToken();
                                             returnData[count] = tokenString;
                                             maintextArea.append(tokenString + " ");
                                             System.out.println(tokenString);
etc etc etc
The problem is that when the tokens are blank, I get an endless loop when I try to print out the data on that last line. How do I deal with Tokens that are blank so they don't endlessly loop my output?
Thanks
MrThis

Most people would probably tell you to use:
String.split(...);
But I'm not most people and I wrote this class before regex support was added to the String class which is based on StringTokenizer but supports empty tokens:

How to set the size of a class that extends JDialog

Hi,
I was trying to set the size of my dialog window to be 600 by 600, but couldn't change it. Here is my code:
public class alii extends JDialog {
/** Creates new form alii */
public alii(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
private void initComponents() {
Container contentPane = getContentPane();
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
closeDialog(evt);
pack();
public static void main(String args[]) {
JFrame frame = new JFrame();
alii a = new alii(new javax.swing.JFrame(), true);
frame.setSize(600,500);
frame.setLocation(200,200);
frame.setVisible(true);}}
Please help me with this and explain to me what is the problem and what needs to be changed.
Cheers

Hi,
The code you sent me doesn't work, and the code I posted wasn't a complete, but there is the complete one. You can see now what the code does.

TS1884 How do you cope with a system that shuts itself down after a safe boot progress bar is completed?

How do you resolve a problem with a system that shuts itself down after a safe reboot and when the progress bar is completed? Thanks.

Thanks for you response - the honest answer is I don't know, not being particularly IT literate. I do know however that I'm running Maverick if that is of any help?
I also tried the Command R route, along with holding some other keys as per the Apple troubleshooting guide, but no luck. My wife pointed out though that the system was running slowly over the last few days and we had quite a lot of the 'spinning beach ball' before being able to undertake tasks.
Lastly, I inserted my start up disk bit as the system is unable to start I'm now unable to retrieve it. All-in-all a real pain.
Appreciate any advice. Many thanks.
