Replaing strings in html pages

Basically I'm looking to write something that searches for a specific string in an html document and then replaces it by something i defined in the code already. so no need to take user inputs, the code will decide already what its going to do. The rundown :
-need the code to search html docs, aka i have a var named stringx and i want to see where in the document it is found
-once stringx is found, i need to go back a couple of spaces as in search backwards for another string (to check a number that is the name) once that number is found, i need to add a link to a filename that is constant + the number found.
is this clear enough?
thanks in advance if anyone can help

Converting a String to HTML page

Hi,
I need to know how can i print a jsp page, throw java application.
1. I have a jsp(html) page whice contains some tables
and data. (this page should be printed)
2. I know how to send a String (which represents the jsp
source code) to a java application(server side)
3. I know how to Print a String.
But it's not enough, because i want to print the page itself
and not it's source code.
Please help.
thanks in advance.

Hmmm ... I tried the same long time ago ... and failed. ;-)
But as I see now, they added some new methods to the engine.
Now I would start here:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper/docs/api/org/apache/jasper/servlet/JasperLoader.html
Maybe it just works when you pass your JSP file to this method:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper/docs/api/org/apache/jasper/servlet/JasperLoader.html#loadClassDataFromFile(java.lang.String)
and write the byte[] in a file.
The problem is, that you just get an class file. (imho, no html file)
But if you execute this class, you should get the proper HTML code...
Hmm... not easy as I said bevore. :-)
Hope I could help you! Let me know if I did.
Happy Coding! :-) ©

Cannot get the parameter from a HTML page at the first time

Hi everyone,
I have a html page with <input name="username" ...>, and the submit action is a url to my JSF web application. In the start page of the JSF webapp, I use following code to get value of username.
FacesContext facesContext = javax.faces.context.FacesContext.getCurrentInstance();
String userName = (String)facesContext.getExternalContext().getRequestParameterMap().get("username");
However, I cannot get it at the first time. The strange thing is if i click "refresh" button, the value of username is shown up on my page.
Why? and How to solve it?
Thanks in advance,

Problem in Opening HTML Page in Internet Explorer from my Swing Application

Hi,
I am opening a HTML file in Internet Explorer from my swing application.I am using the code given below
private final static String WIN_FLAG = "url.dll,FileProtocolHandler";
private final static String WIN_PATH = "rundll32";
String cmd = WIN_PATH + " " + WIN_FLAG + " " + url;
// url is HTML file Path
Process p = Runtime.getRuntime().exec( cmd );
Here there are two things i need to address ...
1)The HTML file is opening up,but it always opens behind the swing application,that makes me every time to maximize the HTML file after it being opened up.I want to open it in front of the Swing Application.I need to implement "Always On Top" functionality for the html page.
2)Whenever i trigger action to open different HTML page,it opens in new Internet Explorer window.
I need to open it in same IE window.
how to solve out these problems ??? any help would be greatly appreciated .Thanks in advance.

Open a html page from an applet

Hi,
I would like to open, from an applet, an HTML page in a new window with a specific width an eight.
Who can help me ?

Here is an example of applet to javascript with liveconnect:
http://www.narhari.com/java/applet2javascript/
You can use the send(String) method from the sample applet to send something like:
window.open('xyz.html','myPopup','width=200,height=200');in order to open a window with specific dimensions
of course you can also build HTML in your applet and use send() + some javascript to render it.

How to display a text file in a html page?

I have written a servlet that executes a batch file whose output is saved to a txt file. I am attempting to display content of the text file as a html page from the servlet but am struggling I have attempted to read the file and output it as shown below but it is not displaying the correct data
Appreciate some help
Thanks in advance
Amjad
Runtime r = Runtime.getRuntime();
Process p = r.exec("C:\\Condor\\test\\QueStatus.bat");
PrintWriter out;
String title = "Que Status";
response.setContentType("text/html");
out = response.getWriter();
FileReader fr = new FileReader ("C:\\Condor\\test\\output.txt");
for (int chr = fr.read(); chr != -1; chr = fr.read()){
out.print(chr);
}

Couple of things. First you should search the forums for how to properly exec a dos batch file. There are some problems you may run into especially with io. I suspect you may not actually be running that batch file at all.
I would test outputing a text file separately from execing the batch file.
Here is some code so you don't have to output 1 char at a time. Setting the content length and closing the output stream might help.
File downloadFile = new File("c:\\blah\\blah\\blah");
response.setContentLength((int)downloadFile.length());
response.setContentType("text/html");
ServletOutputStream out = response.getOutputStream();
FileInputStream fis = new FileInputStream(downloadFile);
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = fis.read(buffer)) != -1) {
out.write(buffer, 0, bytesRead);
fis.close();
out.close();

but it only extracts URLs from <A> (anchor) tags. I want to be able to extract URLs from <MAP> tags as wellGee, do you think you could modify the code to check for "Map" attributes as well.
Can someone maybe point a page containing info on the HTML toolkit for me?It's called the API. Since you are using the HTMLEditorKit and an ElementIterator and an AttributeSet, I would start there.
There is no such API that says "get me all the links", so you have to do a little work on your own.
Maybe you could use a ParserCallback and every time you get a new tag you check for the "href" attribute.

Unable to print HTML pages

After a good bit of reading, I found that printing HTML directly to the printer doesn't work for many printers. I don't want to print the code. I want the actual HTML page. I have some code here that reads the HTML file into a JEditorPane and then is rendered into a graphic for printing.
My code compiles fine, I'm not getting any errors, but what I'm also not getting is any pages printing.
Here is the source of my class:

I think you will find thatDimension d = this.getSize ();produces (0, 0) until you actually display your component somewhere. I believe it's possible to "display" it in such a way that it doesn't appear on the user's screen, but I don't know how.
There's a Swing forum here where you get answers from people who are good at Swing. Posting here attracts answers from people like me who are mediocre at it.I think that calling validate() on a Container will lay it out and size it's components, even if it hasn't been made visible, but don't take my word for it.

How do I change filename for single-image HTML pages in web gallery for LR 3

Hi,
I would like to change the default filename for the HTML pages produced by Lightroom 3 in the web gallery. Specifically, I would like to remove the string "_large" from the HTML filename, so it corresponds exactly to the image filename.
Specifically, the URL by default is like this:
http://www.mysite.com/content/_c_EMT2146_large.html
and I would like it to be like this
http://www.mysite.com/content/_c_EMT2146.html
I assume there is some way to make this change using the template editors, but I can't figure it out.
thanks,
James Riemermann

Turns out there's a fairly easy way to change that on Windows, but I can't figure out an equivalent on a Mac, which is where the need is. On windows, I can edit (after backing up) the following two config files:
C:\Program Files\Adobe\Adobe Photoshop Lightroom 3.6\Shared\webengines\default_html.lrwebengine\grid.html
C:\Program Files\Adobe\Adobe Photoshop Lightroom 3.6\Shared\webengines\default_html.lrwebengine\manifest.lrweb
In which the "_large" string is appended and can be removed, following which the gallery works exactly as I would hope.
But I can't find the equivalent files on the Mac, though I would assume they exist.

How to display an image on the HTML page by using applet

Dear friends,
I am now writing an java applet, I want to display an image on the HTML page, and tried the following commands:
{color:#ff00ff}{color:#000000}Image map; //put in the class definition
map=getImage(getCodeBase(),"hhh.gif"); //put in the function of init()
g.drawImage(map,0,300,this); //put in the function of paint(){color}
{color}
However, when I run it, the image wasn't displayed at all.
I hope who guys ever come across this problem could help me to solve it. Thank you in advance!
Hawaii

Hi,
I am no expert on Images
but
from personal exp.
are you sure that map actually contains the image?
try using
ImageIcon ii = ImageIcon(String name);
map = ii.getImage();I saw a tutorial on images i think on sun
where they use ImageIcon to load the image

Replace HTML page with an applet

Hello to everybody!
I created a servlet who can manage file upload from an HTML page.
Now I want to replace that HTML page with an applet.
I know that I need to use multipart/form-data , but I have no experience with applet.
HTML page code is:
<html>
<head><title>Upload</title></head>
<body>
<FORM ACTION="http://localhost:8080/examples/servlets/servlet/UploadTest" ENCTYPE="multipart/form-data" METHOD=POST>
What is your name? <INPUT TYPE=TEXT NAME=submitter> <BR>
Which file do you want to upload? <INPUT TYPE=FILE NAME=file> <BR>
<INPUT TYPE=SUBMIT>
</FORM>
</body>
</html>
Any help for "translating" this html page into an applet?
Applet will send, like html page, a string and a file.
Thanks in advance, Liuk

If you use something like Apache Http Client you dont have to do any low level implementations.
Also if you are the one who is writing both servlet and applet you dot have to stick to standerd formats. you can develop your own format and write both servlet and applet to handle it. that kind of thing can be done easily even with URLConnection. But if you plan to send large files then URLConnection may not be the right option becouse I have seen many complaining that URLConnection gives OutOfMemoryErrors when uploading large amounts of data.

Can I use multiple p class="logos" tag with the same name within the same html page?

I was told not to use <div class> tags too many times. I was using them for text, images, to clear floats, I basically built my website using multiple <div class> tags. So if I can't use multiple <div class> tags could I use <p class> tags multiple times in the same html page?
I have a string of logos at the bottom of my webpage which will all be using the same css characteristics for all logos. Would this be the proper way to write the code:
HTML
<p class="logos">Logo1<a href="...></a></p>
<p class="logos">Logo2<a href="...></a></p>
<p class="logos">Logo3<a href="...></a></p>
<p class="logos">Logo4<a href="...></a></p>
<p class="logos">Logo5<a href="...></a></p>
<p class="logos">Logo6<a href="...></a></p>
CSS
.logos {
margin-left:10px;
Here's my website: http://www.darbymanufacturing.com/test_website/index.html - this is the website built with all div class tags
I restarted the website in order to write the code properly so that I don't come to errors when uploading on the server like I am having with the website link above.

Instead of writing something like this -
<p class="logos">Logo1<a href="...></a></p>
<p class="logos">Logo2<a href="...></a></p>
<p class="logos">Logo3<a href="...></a></p>
<p class="logos">Logo4<a href="...></a></p>
<p class="logos">Logo5<a href="...></a></p>
<p class="logos">Logo6<a href="...></a></p>
Why not have something like this -
<div id="logodiv">
<p>Logo1<a href="...></a></p>
<p>Logo2<a href="...></a></p>
<p>Logo3<a href="...></a></p>
<p>Logo4<a href="...></a></p>
<p>Logo5<a href="...></a></p>
<p>Logo6<a href="...></a></p>
</div>
with CSS like this -
#logodiv p { ... }

     jframe.validate();
     jframe.setVisible( true );
plz help me

Hi Sandy,
Instead of giving url in the constructor. Paste the code below the JEditorPane. Remove the url from the JEditorPane constructor.
try{
                    /** Files from system */
                    java.net.URL helpURL = new URL ("file:///" + "C:\\thread.jspa.htm");
                    /** Files from inter net */
                     helpURL = new URL ("http://forums.sun.com/thread.jspa?threadID=5421146&tstart=0");
          if(helpURL!=null)
           jHelp.setPage(helpURL);
          else
               System.out.println("Couldnt find file");
           }catch(MalformedURLException exp){
                System.out.println("Exception in page loading---"+exp);
           }catch(IOException ioexp){
                System.out.println("Exception in page loading"+ioexp);
           }

Read Text from HTML-Pages and want to solve "ChangedCharSetException"

Hello,
I have an app that connect via threads with pages and parse them an gives me only the Text-version of a HTML-page. Works fine, but if it found a page, where the text is within images, than the whole app stopps and gave me the message:
javax.swing.text.ChangedCharSetException
        at javax.swing.text.html.parser.DocumentParser.handleEmptyTag(DocumentParser.java:169)
        at javax.swing.text.html.parser.Parser.startTag(Parser.java:372)
        at javax.swing.text.html.parser.Parser.parseTag(Parser.java:1846)
        at javax.swing.text.html.parser.Parser.parseContent(Parser.java:1881)

        at javax.swing.text.html.parser.ParserDelegator.parse(ParserDelegator.java:78)
        at aufruf.main(aufruf.java:33)So I tried to catch them with "getCharSetSpec()" and "keyEqualsCharSet( )" from the class "javax.swing.text.ChangedCharSetException" and hoped that this solved the problem. But still doesen't work...
Then I looked at the web and found, that I have to add the line:
doc.putProperty("IgnoreCharsetDirective", new Boolean(true));"doc." is a new HTML Dokument, created with the HTMLEditorKit. I do not have much knowledge about that and so I hope, that someone can explain me, how I can solve that problem, within my code.
Here we go:

                URLConnection hs = viele.openConnection();
                hs.connect();
