Help!!!! JEditorPane and javascript

i am using JEditorPane in my project to display web
pages. But JEditorPane does not support javascript,
Applet, Shockwave animations.
Is there any way to Support all these things in
JEditorPane by extra coding Sure, but it won't be a trivial task, just like creating your own web browser.
or Using open source code like Mozila's
Rhino ( javascript interpreter ).
Thanks in advanceJava 1.6 has Mozila's JavaScript engine built-in:

HELP PLASE ! JavaBean and Javascript in frames :)

Hello,
First please excuse me for my bad english I'm French think you in advance for your patience and your help ! :)
To resum the problem :
I have 2 frames, a menu frame and a main frame
I use a javabean wich is saved in application variable.
When the pages of main frame use the javabean there is no probleme.
BUT when menu frame calls pages of main frame it don't restore the javabean, it looks like je page called by menu frame, which operates on the javabean, wasn't called, and the changes I do in this page aren't saved
Menu frame uses javascript to calls main frame pages so I think the problem is conjonction of frame and javascript.
But I have no choice because it's volonty of my boss, so please help me ! :)
More precisly :
the javabean : NavigationBean
page frame menu : menu_page.jsp
main pages which use javabean : pageA.jsp, pageB.jsp, pageC.jsp
pageA.jsp has reference on pageB.jsp which has reference on pageC.jsp
Traitement of the javabean NavigationBean in pageA.jsp, pageB.jsp and pageC.jsp :
<jsp:useBean      id="gestionNavigation"
          class= "NavigationBean"
          scope="application">
</jsp:useBean>
<jsp:setProperty      name="gestionNavigation"
               property="request"
               value="<%=request%>" />
(it needs response and request to run)
<jsp:setProperty      name="gestionNavigation"
               property="response"
               value="<%=response%>" />
<jsp:setProperty      name="gestionNavigation"
               property="pageActuelle"
               value="<%=urlActuelle%>" />
(it saves in NavigationBean object the url where user is)
In pageA I clean all NavigationBean so all pages saved are deleted
if user go DIRECTLY on pageA.jsp, all is ok :
user go on
     pageA -> pageB -> pageC
and NavigationBean save
     pageA -> pageB -> pageC
That's good ! :)
BUT if after user go on menu frame it's wrong !
user go on
     pageA -> pageB -> pageC -> menu_page.jsp -> pageA -> pageB
BUT NavigationBean save
     pageA -> pageB -> pageC -> pageB
instead of
     pageA -> pageB
To resume, for NavigationBean when user go directly on main pages there is no problem, but when it uses menu frame it doesn't save that user go on pageA
I clean NavigationBean on pageA, but instead of this problem it doesn't clean and retrieve old datas
It looks like that when user uses menu FRAME it uses an old NavigationBean object, but when it go directly on pages of main frame it runs !
And I use scope application so don't understand, I have tried session scope but no change :(
I have tried using "response.encondeURL" but no change
Think you in advance for your help, and good luck from Paris for all New York people ! :)

It sounds like what might be happening is when the user goes 'back' to the menu, they're not requesting the page from the server. So, they're either getting the old page cached by the browser. Maybe. If you reload the menu page manually, does it work?

Accidently installed NoScript, can't get rid of it and JavaScript has been disabled even though it says it's enabled - help!

I accidently installed NoScript when trying to remove adverts/pop-ups. Now it's causing problems on various sites I regularly use and I can't get rid of it. It doesn't show up on Tools/Add- ons so I can disable and JavaScript has been disabled, even though it shows as 'Enabled'.
Help would be appreciated.

The usual method for uninstalling extensions and themes is by using the Add-ons manager for your Mozilla application, as follows.
# Click "Tools -> Add-ons
# Click on the Extensions or Themes button on the top.
# Click on the extension or theme you want to uninstall.
# Click Uninstall.
# Restart your Mozilla application.

Hi
This is not the forum for this type of question ...sorry. Try the XMLDB forum, XML DB

Does JEditorPane support JavaScript, CSS, XHTML, HTML?

Can anyone confirm what JEditorPane actually can support? I can't find anything specific in the J6SE release notes and most of the stuff of Google is pretty dated, I have also searched the forums but nothing much on there that is recent. According to one post it supports some CSS and HTML but no JavaScript.
Can anyone confirm this?
What I plan to do is make a lightweight split pane editor for the above but I also want to be able to preview the code in another pane instead of launching a browser. If there still is no support then can anyone suggest an alternative way to get the same results?
Failing that I will just have to try and then fall back to the browser but it would be nice to know before hand. The online docs I read don't cover a lot on compatibility.
Cheers

the answer is no. the html support in JEditorPane is
very simple to be able to do things like simple help
manuals and such. But you may be able to integrate
the mozilla gecko engine into your application if you
really want this.

Hi Gimbal,
Thanks for the info. The jrex thing certainly looks more like what I am after.

Error using java and javascript

I have a jsp page that links to a bean and is working fine (getting data from the database).
On a html form I have a button with a picture that fires off javascript when clicked:
<BUTTON TYPE=reset onclick=showinfo('<%=index%>')>
<IMG SRC="http://localhost:8080/Portal/Images/q2.bmp" ALT="Info">
</BUTTON>
The javascript function just opens a new window and displays the text sent in:
<Script Language=JavaScript>
function showinfo(arrayindex)
InfoWin=window.open("","InfoWin","width=345,height=220");
InfoWin.document.write(arrayindex);
return false;
</Script>
Well in the above example index is a number (pulled from the database using a java bean and javascript converts it into a string then the function displays it correctly. If I replace <%=index%> with regular text it works fine as well(because java isn't used to pull data)! The problem occurs when I retrieve text data from the database and send it to the function. The web page gives errors about a nonterminating string. But I can move the code to somewhere else on the form(as long as I don't send it to java script) and it will print the text to the screen. I can also view the source of the web page and the html shows the text from the data base as if I hard coded the text into the javascript!!!!!!!!!!!!!!!!!
This must be a bug between java and javascript!
-can pass numbers(from a database) between the two
-can't pass text (from a database)between the two
Any info would help!

Found the problem myself!
I am using an odbc connection to msaccess and the spaces in the text was messing things up!
After taking out the spaces it worked again.

Use of HTML and Javascript within EP

I have a newbie question:
I have several HTMl documents with javascript embedded like e.g. various calculators we use on the current website.
If I want to migrate these html sources to EP content, what can I best do than?
I assume that all existing html and javascript renders as normal without too many development involved?
Is there a good example how-To source which I can use to demonstrate this?
many thanks for your help

Hi,
Well there are two options:
<b>1) If you are interested to make the portal component and then use in Portal.
2) If you want to use your earlier HTML document as it is inside the portal.</b>
In case 1 you need to make the Portal objects and then make a portal project. You can use javascript in that as well.
In case 2 you can directly make the URL iView of the HTML document and then view it from the portal. Well this is not a good way of using your javascript. Personally I suggest you to go for Portal Project.
I hope this help you!!

Apply formatting in a JEditorPane and export the content in HTML.

Hi,
I'm writing, a program to allow the user to enter a formated text and even add images in a JEditorPane.
Here is a simple sample of the code:
import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;              //for layout managers and more
import java.awt.event.*;        //for action events

</html>By pressing the Save button I can change the selected text.
I don�t know the way to get and apply the format (size, color �) to only the selected text and display the selected image in real time in the EditorPane. Like if you press the Bold button, the selected text font will be change to bold.
I would like to get or save the HTML code of the content of the EditorPane by pressing the Save button, How to make it?
I can apply the formatting on the selected text in a JTextPane, but I don't know the way to save or export the content in HTML. By doing that it could fix my problem too.
So any help to do that will be much appreciated.
Thanks.

Hi,
Tks for your answer. That one I can do it. I would like to display the selected text in bold instead of adding the tag in the JEditorPane. If I get you right, you get the hole content of the JEditorPane and save it. How did you get it ? And before saving that in the database, did you fing the keysWord to convert the HTML tag in the corresponding entities ?
Bellow you have a sample of code to make the formatting in the JTextPane.

Link in new tab opens blank and "javascript:subValue(1)" is seen in the address bar.

On a specific website, when I left click a link it opens but when trying to open the link in a new tab, the new tab opens blank and "javascript:subValue(1)" is seen in the address bar. This website hosts many, many images which I hope to download using a bulk image save addon but those images must first be in separate tabs. Opening these links in new tabs is vital to the process.

Filting html tags, css, and javascript with regex

hi everyone,
im writing a small application where a user types in a url, and the text of the webpage is displayed in a text area.
ive got it to work, however it takes some time, and also alot of content i dont want is displayed - tags, scripts and sometimes css.
initally i filtered out the html tags with a regular expression, but i still get alot of unwanted content.
im not a confident java programmer, and the idea of parsing html, css and javascript is the scariest idea ever to me, so my next idea is to keep only everything between the <body> tags - everything above and below it is deleted - hopefully that should leave me only with the visible content on the site.
ive messed around with regular expressions but i cant get it to work, can anyone help out?
thanks alot,
Torre

I tried out the regexes I posted on the source of a forum page, which is not valid html (contains two each opening and closing body tags). With a bit of trial and error I was able to remove everything upto the first, and not the second, opening tag by using a reluctant qualifier, ^.*?, but couldn't for the life of me achieve removal of only the last closing tag, leaving the other, invalid one intact. How would you do that?Regexes always try to match the first occurrence of whatever they're looking for (the sentinel), and there's no way to change that behavior (but it would be handy if you could). What you have to do instead is make sure the rest of the regex can't match the sentinel. For that you need lookahead, and the simplest way to use it is to scan the rest of the text looking for the sentinel and, if it doesn't find one, go ahead and gobble up the remaining text: "(?is)</body>(?!.*</body).*$" However, if there are many occurrences of the sentinel, you could take a serious performance hit. Here's a much more efficient way: "(?is)</body>(?:[^<]++|<(?!/body>))*+$" After matching the sentinel, this regex gobbles up anything that's not the first character of the sentinel, or the first character as long as it isn't followed by the remaining characters of the sentinel. The advantages of this regex are that it never has to backtrack, and the lookahead is only applied when it's necessary, where the first regex applies it every time.

Netui tags and javascript

          Hello Gang, not sure if anyone has run into this issue, but here it goes.
          I got a netui:form with netui:checkboxes that I need to have a specific type of
          functionality.
          The first netui:checkbox when checked calls a javascript function that enables
          the remaining netui:checkboxes so that the user can check them.
          Except the first netui:checkbox, all other netui:checkboxes need to be disabled
          at run time and then enabled once the first check box is checked, below is the
          code I got thus far, can't get the diable/enable part to work for the netui tags.
          (Keep in mind that this works well with regular html checkbox tag and javascript)
          The following code wont generate javascript errors.
          It's not doing anything in terms of enabling/disabling the netui:checkboxes.
          <script language="javascript">
          function checkBoxDisable()
          document[getNetuiTagName("updateForm")][getNetuiTagName("tue")].disabled=true;

Problem of Java - javascript and javascript - java communicate of same obje

Hi all,
I have met a great problem in program an applet! I have tried to communicate between java and javascript and javascript and java in the same page by using jsobject. However, problem occur. It is not a problem to call javascript from java by using jsobject. However, javascript call java by using document.object.function has problem. It cannot find out the object in IE. I have followed the webpage show in java, but the browser still prompt me the object called client not find. Please help!! My html code is shown as follow:
<HTML>

Thanks your kindly help.

Everthing looks fine to me from here, you should be able to just call the java function direct such as
document.myAppletObj.doMethod();
I think your problem could be that your object is called "client". IE can get funny about names, it didn't like me calling a method delete()!!
Try adding something else to the name such as "my_client", and see if this works any better.

HTMLEditorKit : How you handle FRAMES, IFRAMES and JAVASCRIPT

Hi all,
Currently im using the HTMLEditorKit to parse through the HTML page. Obviously its easier when the elements are on the body of the page. But what if the page has frames,iframes or javascript and i want to extract links that these elements reference to. How do i do it? I know some of you would recommend my class to extend the parsercallback class. But is there a way for example i can use 3 or even 4 different iterators each pointing to the different elements ?
and lets say if i reference to a SCRIPT tag of the HTML, how do i extract the possible URLs in it. Same goes for iFrames and JavaScripts. Can anyone please help me with this ?

Tim,
The form action needs to be the page URL. The INPUT fields/objects of your form will be sent as parameters when the form is submitted. These parameters can be read by your portlet by using the parameter passing PDK services. It is recommended to use qualified parameters in case the portlet that reads the parameters is the same as the one that has submitted them.
As far as I remember the parameter passing sample portlet contains similar code to what you're looking for.

Help Library Requires Javascript

Whenever I try to use the Logic Pro 9 online Help from the menu bar Help item, I get the message
The Help Library requires JavaScript.
If JavaScript is not enabled, you will not be able to view all the content.
So how do I enable JavaScript?

A bunch of us have had this problem, too. The solution I found in another of the notes dealing with this was to open a Terminal window, and enter the line:
defaults write com.apple.helpviewer WebKitJavaScriptEnabled 1

Help: JEditorPane displays all HTML content centered

I'm using a JEditorPane to display the contents of a simple help file written in HTML.
The problem is that the help file is displayed with all elements centered! That is, every element is displayed as if it had the <CENTER></CENTER> tags around it. The page is not written this way, and displays normally in regular web browsers.
It's a really simple help page, and was written by hand. I have checked, and all of the tags used in the page conform to HTML 3.2. Does anyone know what might be causing this problem?
   private JEditorPane createEditorPane()
      JEditorPane editorPane = new JEditorPane();
      editorPane.setEditable(false);
      editorPane.addHyperlinkListener(new Hyperactive());
      if (theHelpFile != null)
         try
            editorPane.setPage(theHelpFile); //This is a string, the URL to the file
         } //end try
         catch (Exception e)
            System.out.println(e.getMessage());
            System.err.println("Bad URL: " + theHelpFile);
         } //end catch
      } //end if
      else
         System.err.println("Couldn't find file: "+theHelpFile);
      } //end else
      return editorPane;
   } //end createEditorPane

If you are using the standard HTMLEditorKit that comes along with JEditorPane, you should note that it only supports HTML 3.2. This may be the problem. Check page source if div's and similar are used or if the page has "HTML 3.2"-old elements like table's or similar to control layout/display.
