Is it possible to write an HTML editor using Java?

I have this final year project (for my degree), where I need to use Java to write an HTML editor.
It doesn't have to be fancy or anything, just need to be able to generate HTML files from the GUI frontend where text, images and tables will be created.
I'm new to Java, and I'm having problem with it.
Please help, I only need to know whether it's possible, and possible a little guideline on how to go about it, please?

WebEnterprise - HTML Editors and Java

I'd like to know any opinions on HTML editors and their use with
WebEnterprise. Have any of you done
evaluations to determine the best editor to use with the Forte product? Also,
do you have experience using
a Java applet as the front-end to a Forte service object? In this instance,
are you able to do so with Forte 30f2 and
WebSDK?
Thanks,

Peggy,
FrontPage 97 / 98 have both worked really well for us, however we
discovered a slight hitch with 98 where the Editor would gobble up
<?FORTE ..> tags inside the SELECT OPTION tag, but you can work around
that one, apart from this FP98 is a great HTML editor. I also thought
HotMetal was a good fit.These observations come out of evaluating about
5-6 leading HTML editors.
Some recommended steps in the process:
1) Create a prototype by laying out all the HTML using an Editor. Figure
out all the navigation within your web. More recent features seen in
HTML editors such as JavaScript generation and DHTML / CSS support are
really difficult to work out on your own, let the advanced Editors do as
much dirty work for you as poss.
2) Once the prototype is finalized, for all the pages requiring any
dynamic content generation, figure out all the Tag Handlers you will
need. Change the HTML Content by inserting the FORTE tags as required,
code the corresponding Handlers.
3) Figure out the relation between page requests and the security
requirements for your pages, design the Session properties and data
tracing across requests using the Session object.
4) Do refer to all the Tech Notes on the Forte web site for known
issues.
As for the Java applets frontend, we have used Java - IIOP - Forte since
early beta through every Forte release (3.0.X) and it works fine with
WebEnterprise and release 30f2.

I am making a photobook through iPhoto for my Guest Book for guests to sign at my wedding. I was wondering if it's possible to write on the paper used in the book with ink? With some photopaper this isn't possible.

Possible deadlocks with in-memory database using Java

I've written a completely in-memory database using the Java API on BDB 4.6 and 4.7 for Windows and Linux (x86). The completely in-memory database means the database content and logs are entirely in-memory and the overflow pages will not be written to a disk file.
The database environment and the database are configured to be transactional. All database access methods are specified to be auto-commit by setting the transaction argument to null. The environment is configured to be multi-threaded (which is the default when using the Java API).
When run with a single-threaded client, the application works correctly on both Windows and Linux for BDB 4.6 and 4.7.
When run with a multi-thread client that uses two thread for the database access, I run into a deadlock inside the call to the Database.delete method about half the time.
I am assuming that in the "auto-commit" mode, a deadlock should not be possible.
Any reported problems with using Java with in-memory database?
Thanks.
Hisur

Hi Hisur,
If you are using transactions and multiple threads, you will have to deal with deadlock. In this particular case, it's likely that a delete is causing two btree pages to be merged (called a "reverse split"). Auto-commit makes no difference in this case -- the application must retry the operation.

How to create hyperlink in Html page using Java

Hello every one
I want to know that how can I create a hyperlink in Html page using java ?
Let for example
I have code like this and i want to give hyperlink to it using java.
rember that i am creating node using this id="name" which give me multiple value. and i want to assign diff link to each name..?
<tr>
<td ><span id="name"></span>
</tr>

but i m using this code to create node in html file
HTMLLIElement li = (HTMLLIElement)appHTML.createElement("LI");
Text txt = appHTML.createTextNode(name);
li.appendChild(txt);
appHTML.getElementById("name").appendChild(li);
this will display all name value which is coming from database,
and i want to assign a hyperlink to it,
I have id with name also so I thought that using id i will
create javascript like
function popup(id)
     if(id==1)
          var n1 = window.open("../list/name1.html");
     if(id==2)
          var n1 = window.open("../list/name2.html");
this way i want to popup particular file if i can pass id value in this function
so want hyperlink like
name

How to write a messenger with using java?

May I know how to write a messenger with using java? The messenger need included two functions which are file transfer and add users to join the conversation.
Thank you.

Ok, so you need to start from the beginning, the requirements, is it a swing (i.e. GUI) app, web app, console, etc...?
As stated by sprizor making an IM client is no easy task, you need to both implement the server side and the client side, which both communicate with each other, file transfers are also quite complex, and even maintaining a multi-user chat can be quite difficult.
If you are after a Web Based app, then you will need to look into Push technologies, like Grizzly Comet which is a nice wrapper for the NIO java stuff:
https://grizzly.dev.java.net/
Good luck...

Is it possible to make a code editor in Java?

I'm new to java and so i'd like to know if it would be possible to make a simple code editor for Mobile Phones with Java.
The code editor will be for GML.
I'd like to make it so that the code can be easily edited on a wide range Mobile phones (not necissarily smart phones).
If this is possible, I would greatly appreaciate any help or advice. Thanks.

Even day in this forum we see what code looks like when this advice is not followed.my first java code 5 years ago was an applet with a changing 2d function being animated.
it worked after 2 grueling days and i was so happy because visual feedback was my only motivation.
so its hard to say. granted, my code was awful for a long time.I'm thinking of the guy last week who had Swing+JDBC code and kept pestering for help on an obvious syntax error (he was invoking a method with no arguments when it was defined to take a String array) and for the life of him, he couldn't see the error or understand the error message. Posters kept telling him to learn the fundamentals first, but he was stubborn and kept demanding someone fix his syntax error...

Creating a small HTML-Editor using JEditorPane

Hello! I'm trying to create a small HTML-Editor. Via this editor users shall be capable to create formatted text (bold, italic, underlined, different sizes, different fonts, different colors). Furthermore, if the user pushes the enter-button a new line-break (<br>) shall be inserted. Basically my editor is working but with some big problems:
1. When I create an instance of my editor, I initialize it with some html-code.
this.m_EditorPane.setText("<html><head></head><body></body></html>"); Without this initialization between the <body> and </body> <p> and </p> will be inserted, what I don't want. But if I push now the enter-button at the beginning, <br>-tag will not be inserted in the <body>-area but in the <head>-area.
2. Styling text is working really good, but when I insert a line-break (via enter-button), the <br>-tag is inserted after the (e.g.) closing bold-tag (</b>). So, in the next line, this style-property must be reselected.
Can anybody help me to change this behavior?
Kind regards, Stefan
P.S. The way I insert the <br>-tag:
JEditorPane editor = getEditor(ae);
HTMLDocument doc = getHTMLDocument(editor);
HTMLEditorKit kit = getHTMLEditorKit(editor);
editor.replaceSelection("");
int offset = editor.getCaretPosition();
kit.insertHTML(doc, offset, "<br>", 0, 0, HTML.Tag.BR);
editor.getCaret().setDot(editor.getCaretPosition());P.P.S. Sorry for my bad english :-/

Is it possible to write an operating system in java?

Our highschool requires us to do a senior project to graduate. It has to be something you want to do as a career. I want to be a programmer so I thought it would be cool if I wrote an operating system. I really don't know where to start though, I thought you couldn't write an operating system in a high-level language at first but then I heard differently. I can see why you'd have to use assembly or someting to write one because it has to be in bionary but i guess that is not true. So is it possible to use java to write an operating system or is that just not possible? I'm only a sophmore right now so i have two years to figure it out but i'd like to get an idea now.
thanks, lateralus

it's not going to have a gui or anything like that,
it's just going to be something similar to DOS. It
really doesn't have to do much. I just like the
challenge, also I heard someone else in my school had
done it and they use java.You sure that you don't just want to write a command shell?
When you open a console window on windows that is a command shell, not an OS.
And writing one of those would be a lot easier than writing an OS.
I suppose you could write a very primitive pseudo OS using the Sun VM. However I am not sure that you would really be able to demonstrate the concepts of an OS except in a very complicated way. For example if you had the following 'OS' commands
1. Store file
2. Print file
Then you could implement it in the following way
- Create a big binary file managed via java
- Storing a file means 'managing' a hunk of that binary file and 'mapping' the file into that space.
- Printing the file would mean
....a Get map to access file (so find it in binary file.)
....b. Read contents (read bytes from binary file)
....c. Print contents to JFrame (or GUI thing)
If the above seems confusing then unless you have a teacher that is either willing to be very free with what a success is or a teacher that understands the concepts very well then going with a command shell would be much better.

How Do I write an XML file using Java?

Hello there!! to everyone reading my post.
I have this project I need to do, and I have no clue where to start, I was wondering if you guys could help me out.
I need to know how to write an XML file using a Java Program, but without using a Third party library.... just using java native APIs.
I will probably take the values to construct the file from a form.
I will certainly appreciate if you could post some sample code for me.
Thank you very much in advance..

Hello there!,
I have some doubts about the Tutorial I am currently reading. correct me If I'm wrong, but the section "Write a simple XML file" teaches you how to do so using a text editor. I need to create my XML file from a running Java Program written by myself, that takes the values to build it from some variables.
If I'm totally wrong about what I'm saying, could you please point me to where I can find the information of how to do what I'm asking for, inside the tutorial.
Thank you very much,...
sincerely.

outf.flush();

Hi,
when I look in the JDK1.4.2 specification I don't see any write method in the Document interface.
However, your solution is the Transformer class. There you transform your DOM tree into any output you need. Your code sould look something like this:     TransformerFactory tf = TransformerFactory.newInstance();
     // set all necessary features for your transformer -> see OutputKeys
     Transformer t = tf.newTransformer();
     t.transform(new DOMSource(xmlDoc), new StreamResult(file));Then you have your XML file stored in the file system.
Hope it helps.

Edit HTML File using java

Hi....
I have a report in HTML format and a list of thresholds in txt format.
Now, using java how can I:
1. Compare the values in the report with the thresholds
2. Edit the report such that values over the thresholds are highlighted in say, red colour.
I am new to Java programming, so java jargons won't be of much help. I read about jeditorpane but it's primary use is to display html file(that is what i inferred). Is their a way in which i could accomplish the above using jeditorpane??....how do i do the comparison part??

How to submit a html form using java

hi friends,
i have a html form with some input fields, when ever a user submit the form the user information is stored in the database. is it possible to pass the user information in the url(url rewriting) and submit it by a java program so that the data will be stored in the database, as like as, user submit it manually.
for eg:
/*sample.html*/
<form action="store.jsp" method="post">
User Data:<input type="text" name="userdata">
<input type="submit">
</form>
in my java is it possible to store the record as below:
URL url=new URL("http://localhost:7001/webapp/store.jsp?userdata=AutomaticDatasave");
URLConnection con=url.openConnection();
int i=0;
while((i=con.getInputStream().read())!=-1)
System.out.print(i);/*it has to print the data that store.jsp is returned like information stored or error storing data(what ever)*/
