Inserting JAVA program in HTML

I want insert a program made with JAVA in a HTML file. How can I do it? I think is not possible!!
THANKS, JUAN

I have a hard time believing that this can't be an applet. You might not want it to be an applet, but you should be able to do anything in an applet that you can do in an application. The only way I know to run it on a web page is to make an applet.
If this has to be an application, I think you're only option is to allow the user to download and run it.
Here is a link for making jar files more or less runnable.

How to call java program by HTML page

Hi guys,
I'm new java programer and want to build an HTML page to access to ORACLE database on NT server by JDBC, Can anyone give me a sample?
I already know how to access database by JDBC, but I don't know how to call java program by HTML page.
If you have small sample,pls send to me. [email protected], thanks in advance

How to show java program on html

i have gotten some program fm a website. the program was in java form which is save as .class. can i know how do i display my result in the html??
thanks alot!!

you may write a applet,for example:
import java.awt.*;
import java.applet.*;
public class Testexample extends Applet {
     public void init() {
     public void paint(Graphics g) {
          g.drawString("Welcome to Java!!", 50, 60 );
compile this java.and then write a html in the same path with Testexample.class:
<HTML>
<HEAD>
</HEAD>
<BODY BGCOLOR="000000">
<CENTER>
<APPLET
     code     = "Testexample.class"
     width     = "500"
     height     = "300"
     >
</APPLET>
</CENTER>
</BODY>
</HTML>
now you may show this java program from html

Table Entry Insert - Java Programming Question

I design table input/output interface with adding / deleting entry function. Table data will be saved in AbstractList by BAPI.
In Controller implementation tab, I created "input" under WD_init()
   Bapi_Entrysheet_Create_Input <b>input</b> = new Bapi_Entrysheet_Create_Input();
   wdContext.nodeBapi_Entrysheet_Create_Input().bind(<b>input</b>);
   <b>input</b>.setEntrysheetheader(new Bapiessrc());
In view action function, I need "input" as.
input.addEntrysheetservices(new Bapiesllc());
My question is how I can let view class know "input".
Thanks.

Hi li dong,
You need to establish context mapping between view and controller. Open view, select "Properties" tab, In "Required Controllers" section press "Add" and add your controller. Create model node in view (Bapi_Entrysheet_Create_Input) and click "Edit context mapping" in context menu for node. Establish context mapping. Than you can call
wdContext.nodeBapi_Entrysheet_Create_Input().modeObject().addEntrysheetservices(new Bapiesllc());
from view.
Best regards, Maksim Rashchynski.

Where does this java program read a text file and how does it output the re

someone sent this to me. its a generic translator where it reads a hashmap text file which has the replacement vocabulary etc... and then reads another text file that has what you want translated and then outputs translation. what i don't understand is where i need to plugin the name of the text files and what is the very first line of code?

without what arguments?Without any arguments. If there are no arguments, there are no arguments of any kind. If you have a zoo with no animals in it, it's not meaningful to ask whether the animals which are not there are zebras or elephants.
does it prompt me to give it a text file name?Apparently.
when i run it this is all i get:
usage: Translate wordmapfile textfile
Press any key to continue...Right. And "wordmapfile" is almost certainly supposed to be a file that holds the word map, and "textfile" is almost certainly the file of text that it's going to translate.

Using the Insert statement in a Java program without hardcoding the data

hello.
this is james mcfadden. i have developed a program called Demo.java, which is used with another program called QueryTableModel.java (a program that allows data to be viewed in a JTable). The Demo.java program displays a menu, connects to a database, allows the user to add data into the database and allows the user to view data that is already in the database. I have a problem with the Demo.java program. I have hardcoded the Insert statement in it. How do you use the Insert statement to put data into a database without hardcoding the data?

It's pretty straight forward, first parse the xml file with the *[best java xml parser|http://www.google.com/search?&q=parsing+xml+in+java]* and then go through the nodes and construct the html with strings and concatination. Then write the file using *[the best java file writer|http://www.google.com/search?hl=en&q=writing+to+a+file+in+java]*.

How to trigger a java program on INSERT in SAP HANA

Hi,
I need to trigger a java program whenever an INSERT happens on a table in SAP HANA.
Please tell me how can I achieve the same.
Thanks & Regards
Divyank Mehta

Hi Mehta,
HANA SQL Script is not able to call external commands . May be from the context of your Java , you can keep pinging the database where the insert is happening for a data change via JDBC or ODBC . From SQL Context I don't think it is possible.

I need my java program to read HTML tags from the browser...

so, i've made this java GUI, which can run from my internet explorer toolbar...
as of now, this program doesn't do anything, it just produces an interface with blank fields
i want these fields to automatically add information about the current web page on the browser... basically, is there any way that my java program can automatically read the HTML source of the web page opened? i just need it to be able to capture the page's URL and title.
i programmed it using NetBeans, and it runs from the .jre file outside of NetBeans. I got an icon for it to appear on my IE toolbar by editing my computer's registry. When I click on this icon, my GUI runs, but doesn't do anything. Can I get it to read (i.e. automatically output on one of the textfields on my GUI) the URL and title of the webpage that i'm currently on? I want this to work like Bookmarks/Favourites does, so that means i don't want to download every single webpage before reading from it.
any help will be greatly appreciated.

I think that if you wanted to do this, it would involve something like the following:
Have your toolbar GUI listen on a local port
Set IE to proxy to localhost at that port
Tunnel/proxy all requests. This will allow you to intercept the page source and the original request. Between the request URL, the request payload, the HTTP headers of request and response and the response payload, that's everything the browser would 'see'. The downside of the above is that you cannot intercept SSL (HTTPS) requests. You might be able to use the Windows/IE API (native) to fetch page source, but this would definitely be an application and O/S specific solution.

Viewing a HTML document in my Java program

Hi,
My Java program has a JTextPane that can display plain text or HTML documents. This program can mark up certain parts of the document to draw the user's attention.
However, I am having problems when it comes to marking up some of the HTML documents. When they are first loaded onto the JTextPane, they appear fine. When I then run the method to apply the mark up styles, I notice that the text turns the same color as the background after a certain point - making it impossible to see the document or markup.
The HTML (or text) document on display is made into a StyledDocument. And this is how the View for the HTML documents is created:
HTMLEditorKit htmledkit = new HTMLEditorKit();
ViewFactory myHTMLViewFactory = htmledkit.getViewFactory();
return myHTMLViewFactory.create(elem);
Note that elem is an Element -.-
- I tried modifying the color tags in the HTML document, but even when I made the text black and the background white, the text still goes white. If it's a black background, the text goes black, etc. The markup style is actually trying to turn parts of the text red - and it works almost all of the time, apart from these certain documents.
- I then tried applying my own style whenever a HTML document is loaded in, in the hope that I could force the background white and text black, regardless of the tags:
MutableAttributeSet att = new SimpleAttributeSet();
StyleConstants.setForeground(att,Color.black);
StyleConstants.setBackground(att, Color.white);
doc.setCharacterAttributes(0, doc.getLength(), att, false);
The resulting document display kept the original HTML background color, but wherever there was text it looked like someone had run a highlighter over it to change the background white and text black. Kinda ugly! And it still didn't work - come markup time this style was ignored after a certain point.
- This is one of the HTML documents that causes the problem:
<html>
<head>
<link rel="STYLESHEET" type="text/css" href="mystyle.css">
<title>My Document</title>
</head>
In the body tag:
<table>
table here... this displays fine
</table>
And here is the problem point:
<table width=100% cellspacing=0 cellpadding=0>
<tr>
<td>
<table width=100% cellspacing=0 cellpadding=0 style="padding: 3px; padding-top: 6px; padding-bottom: 6px;">
<tr>
<td width=100% style=" padding-left: 6px; padding-right: 6px;">
<table class=pane cellpadding=0 cellspacing=0>
<tr>
<td width=100% class=panetitlebox align=Center >
This is the last text that gets displayed! After this sentence, text goes same color as background.
</td>
</tr>
<tr height=100% valign=top>
<td class=panebox colspan=2 align=Left style="padding: 0px; border: solid 1px; border-top: none;">
<table width=100% cellspacing=0 cellpadding=0>
<tr>
<td class=content align=Left style="padding: 4px; background: transparent;">
<b>Bold text that doesn't show</b> More text that doesn't show
And so on....
In the header tag of another HTML document that has the same problem, it says it is HTML version 4.0. I have looked up the Java API and found that the javax.swing.text.html package is still 'migrating' towards HTML 4.0 and only supports HTML version 3.2. (Even in the API for Java 1.5 beta, although I use Java 1.4.2)
So I assume that Java just can't handle my documents! I also think that most of these HTML documents were generated by a program (I think I saw Frontpage in one of the document's meta tags), because when I make my own HTML it doesn't have the problem.
But it would be nice if my Java program can support these documents, so does anyone have any suggestions as to how I could get these documents to display properly once I apply mark up styles?
If I haven't explained something properly, I will clarify as it is a complicated program, and I've been driving myself crazy with this problem for several days!

I was looking through the HTML document removing pieces of code to see where the problem was. I removed all code relating to styles, alignment, width, padding etc, with no luck. The document has several tables, many of them nested, so I added some comments to see where each started and ended. After I added the comments, I checked the document in my Java program again, ran the mark up styles, and it suddenly worked! So I removed each comment one by one, checking each time, until I found the one that made it work. I then tried typing in the same spot, adding an extra space, moving the <tr> tag onto the same line, but only the HTML comment made it work. Here is the part of the document where I added the comment (it's in bold)
This is the last text that gets displayed! After this
sentence, text goes same color as background.
</td>
</tr>
<tr height=100% valign=top>
<td class=panebox colspan=2 align=Left style="padding:
0px; border: solid 1px; border-top: none;">
<table width=100% cellspacing=0 cellpadding=0> 
<tr>
<td class=content align=Left style="padding: 4px;
background: transparent;">
<b>Bold text that doesn't show</b> More text that
doesn't showDoes anyone know WHY this is happening? It's so weird. I thought if it was something more obvious, like styles, I could just get my program to remove them when reading in the document. But added HTML comments????
Thank you ^_^

How to edit the existing data in the XML file from java programming.

Hi all

xml4j.jar u can download this file from here
http://www.alphaworks.ibm.com/tech/xml4j
or we can use the SAX(simple API for XML)
some sample applications for this

Using a Java Program to execute JavaScript from a website

Okay, let me try and explain as good as I can. I have a program now, that searched through all files and folders in Unix (Solaris machine) and gets the list of files in the bin and sbin folders.
Well, I want to find the version of each of these files from the bin and sbin folders and not all of them have the -v, -V or -version feature (or any others there may be). But, I found this page:
http://sunsolve.sun.com/pub-cgi/fileFingerprints.pl
where if you go to the page I can find an md5 number, place it in the box and click submit to find versions, if available.
My thing is, as I find the number from my java program, I want to be able to open this page, insert in the box (or maybe even call the javascript function) and then submit to get the version numbers. That would mean I could need to get back info from the javascript function.
I hope that explains what I need and hope that someone can help me.
I have found information on the JSObject, but not sure what that means exactly so if someone can explain this:
JSObject win = JSObject.getWindow(this);
JSObject doc = (JSObject) win.getMember("document");
JSObject loc = (JSObject) doc.getMember("location");
String s = (String) loc.getMember("href"); // document.location.href
win.call("f", null);
it would be greatly appreciated. But, this may not even be what I need. I see that the win.call is where I would call the function needed and I am guessing the null could be where I put the number if that is how the function i need works like that. But, what I dont understand is what "document" is and "location". Also, i the "href" the page I put above? I am just lost on that. Hope someone will understand.
Thank again for the help!

Exactly so. Check out the last item - reading and writing to a URL - writing to a URL.
Pulling out the form code from that page:
<FORM METHOD="POST" ENCTYPE="application/x-www-form-urlencoded">
<TEXTAREA NAME="md5list" ROWS=16 COLS=66 MAXLENGTH="33792"></TEXTAREA>
<BR><INPUT TYPE="submit" NAME="submit" VALUE="submit">
<INPUT TYPE="reset" VALUE="reset">
</FORM>You should end up with something like this (copying and pasting from the example):
URL url = new URL("http://http://sunsolve.sun.com/pub-cgi/fileFingerprints.pl");
String sNumbers = "put your serial nos in this string"
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
PrintWriter out = new PrintWriter(connection.getOutputStream());
out.println("md5list=" + sNumbers);
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null){
// read in the HTML page result for later parsing?
in.close();

Running a java program at "Start Up"

Besides running an html file with an applet in it. Are there any simple ways to launch a java program every time the computer is turned on.
I am not asking for specific directions, but rather just an idea, and i will go find my own guide.

Well two ideas (if ur on windows) u could try are -
one, if you had a class file you could simply create a
batch file on windows that says java <class> and then
put that batch file in your startup so that the class
is run at startup or else you could think of modifying
the registry keys on windows to run this class at
startup - whichever works for you.Or you could just jar the program up, adding a Main-Class indicator in the manifest, and then add a shortcut to the jar to the startup folder, as someone else stated. Theres little need to go messing around with DOS batch in modern windows.

Running a java program via a batch file

I am unable to run a java program from a batch file that I created.
spiderpackage.EntryPoint is a class file which I am trying to run with a -v option to output something.What should I do to get the output?
echo ^<html^>^<body^>
echo hello^<br^>
call java spiderpackage.EntryPoint -v
echo ^</body^>^</html^>

This has nothing to do with java programming. Have a look at the windows help for the call command.
The echo <html> stuff doesn't make sense. What's it for?
The command in you batch file should be:
java -cp . spiderpackage.EntryPoint -v
assuming that java is in the system path, and the EntryPoint.class is in a directory called spiderpackage which is a subdirectory of your current working directory

Error while executing HelloWorld.java program

Hi All,
I am trying to execute the samples(HelloWorld.java) program from Jdeveloper and provided the following details in runtime.defaults:
CONTENT_DB_URL
ADMIN_USER_NAME
ADMIN_USER_PASSWORD
however getting the following exception:
FdkException:
Error Code: ORACLE.FDK.UnexpectedError
Detailed Error Code: ORACLE.FDK.FeatureNotEnabled
Trace Id:
info (NamedValue[]): null
can any one please help me to resolve this issue.
Thanks
Krrish.

See the Cleartext Authentication note in the running_client_samples.html file of the CDB devkit.
The default configuration for an out-of-box Oracle Content DB installation allows Cleartext Authentication only if SSL has been enabled (and the Web Services connection string begins with https). See the authentication topic for details.
To allow Cleartext Authentication to take place over standard (non-SSL) HTTP, set the Oracle Content DB domain property IFS.DOMAIN.WS.CleartextAuthenticationRequiresHttps to false using Enterprise Manager (Application Server Control). See the Content DB Administration Guide for details.
If the domain property above is not modified to false and Cleartext Authentication is attempted using using standard HTTP, an FdkException will be thrown:
ORACLE.FDK.UnexpectedError : ORACLE.FDK.FeatureNotEnabled
cheers
Matt.
