Launching java executables in html

<p><span style=" font-size: 18.0pt; line-height: 115%;">I am tryingto get the analyzer html client to function the same way as theanalyzer java web client. All seems to be working well exceptfor launching executables, or basically any link that pointsoutside of analyzer. What can I to get the html version to linkoutside of analyzer?</span></p>

Hi
Look if you want that the code runs in the server side you need create a servlet (that not have any awt stuff) or a JSP (does not have awt to ) that are codes in java that you can put in a html code (CGI like) the code that you write here is for an applet and that MUST run in a client or you can create the applet inside a Application frame and it will run in the client or in the server
perhaps you need another approach of this you can made a application that runs in the web servers as an executable and create a client side awt interface that made a connection with the application running in the server that means you will use RMI or corba
just choose

Executing an HTML file within java program

I want my java code to be able to open/execute an HTML file that I have. How do you do this?
Thanks.

You can display html in a java app, but it is not so simple to run a browser. What you want to look up is the WebBrowser class. Here is an excerpt from some code of mine that displays a url in the browser app in a panel, but there's some chaff in my code you would not be interested in (I'm using a card layout). You're better off loocing up org.jdesktop.jdic.browser which contains the WebBrowser class    /**
     * Reveal the container with the browser display. The browser display is
     * currently hidded using a CardLayout, so it is a simple matter to swap
     * displays; however, we put off actually loading the web page until the
     * first time the display is revealed.
     * @return true if the URL could be resolved and the given web page
     * displayed.
    public boolean showBrowser(
        java.net.URL pURL )
        // See if the web page component has not initialized.
        if ( pWebBrowser == null )
            pWebBrowser = new WebBrowser();
            pBrowserPane.setViewportView( pWebBrowser );
        if ( aLastURLVisited == null || ! aLastURLVisited.equals( pURL ) )
            pWebBrowser.refresh();
            pWebBrowser.setURL( pURL );
            aLastURLVisited = pURL;
        pDualLayout.show( pDualPanel, BROWSER_PANEL );
        return true;

Opening HTML from Java executable?

I have an HTML file that will be located on a CD that spawns off an installation. I need to call this HTML from a java executable. How do I do this?
Thanks,
Scott Roth
[email protected]

You may adopt a refined solution trough the swing package.... Usign the application to shows the HTML file with a JEditorPane or JPane component.
take a look in the jdk1.2.2\demo\jfc\SwingSet\HtmlPanel.java
In this case, your app may becomes slow, but if you will run it in a powerfull machine (128Mb RAM, 16Mb Video) then don�t worry - it works.

When trying to launch a Java preferences get this message: Cannot launch Java application A static initializer of the main class threw an exception: java.lang.NullPointerException"

I have an IMac 10.5.8 and I am having problems with Java. I have tried todownload Java for Mac OS X 10.5 Update 4 and it looks as if it is doingsuccessfully, but I cannot see where it has put it and get this message when trying to launch Java preferences:
Cannotlaunch Java application
A static initializer of the main class threw an exception:java.lang.NullPointerException"
Couldyou please help?

Hmm, only way I know would be a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

JAVA 5.15 / HTML/ FLASH 5/ WIN98 SE questions

I'm a green Java 5.15 /HTML /Flash 5 user, with a PIII 450MgHz computer, using Win 98 SE. Whew! Now that the important preliminaries are out of the way, here are my problems:
1) Most programs I've installed, have indicated where they will install and they add menu (and submenu) items in the Start Menu. Java 5 (update 15) did not. Why?
2) The Java does not come with a compiler/decompiler/editor. Is there an all-in-one that I can download? Do I need a compiler to produce an executable which will run on any OS/Browser platform?
3) When I run the VERIFY INSTALLATION, only the first part is successful (Duke); and then only skewed, because it tells me that I have Win XP installed!! :-) LOL.. The second part of the result shows me a red X, indicating some applet failure. I guess this verification is meant for latest Java 6-update 9, right?
4) Is Java 5.15 compatible with HTML and Flash 5? In other words, can I write a simple initialize/increment variable routine in Java, and have it interface properly with the HTML that embeds my Flash 5? The goal is to load my Flash files at a particular frame in the movie, depending on the value of the variable (set in Java).
Sincerely,
Jakob
Montreal

Dear Inryii,
2) Yes, I do have some rudimentary knowledge of Java and programming in general. Are you suggesting a text editor like Notepad? I would prefer a Java editor which could show me syntax errors. Any suggestions?
3) What is there not to understand about the link: http://www.java.com/en/download/installed.jsp ?? You just click on the VERIFY INSTALLATION button to see if the Java you just installed, did so correctly. In my case, the Java installed itself (with the automatic install wizard) in a manner that I am not used to. The bottom line is that the verification was only partly correct because it was checking for Java 6 update 9 on a minimum OS of Win2000. I have Win98 SE.
4) Again, what is so mysterious about Java 5.15 being compatible with HTML and Flash 5? In a nutshell, here is what I want to do: Initialize a numeric variable in Java, and either have Flash use this variable on the Home page, or load the Home page from the beginning.When a certain page is called, increment this variable in Java and again, either pass this variable to Flash, or load Flash at a particular frame. Is this possible?

Change language of tab Launcher.java UI shell

hi
Im using Dynamic Tab UI Shell template
in launcher.java
public void launchSecondActivity(ActionEvent actionEvent)
_launchActivity(
"Next Activity",
"/WEB-INF/flows/second.xml#second",
false);
i want to change "Next Activity" to arabic language , when i write a aword in arabic it is converted to "????"
Studio Edition Version 11.1.1.3.0 ,Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660
thanks

hi
the problem solved
use this
String toarabic(String tab){
try{
tab=new String(tab.getBytes("iso8859-1"),"windows-1256");
catch(Exception e){
e.printStackTrace();
return tab;
then in change your code to
public void launchSecondActivity(ActionEvent actionEvent)
_launchActivity(
toarabic("write_arabic_Text"),
"/WEB-INF/flows/second.xml#second",
false);
note: in every jspx page the following code must be added
<?xml version='1.0' encoding='windows-1256'?>
<jsp:directive.page contentType="text/html;charset=windows-1256"/>
But i think in jdeveloper 11.1.1.4 they solved this problem without the above code ( im using 11.1.1.3)

Problem while calling java function from html

when i tried to call a java function from html i'm getting an error
object don't support this property.
what could be the reason.
This is my html.
I got this from this forum only.
My applet is accessing the system property "user.home".
I ran it in IE
<DIV id="dvObjectHolder">Applet comes here</DIV>
<br><br>
<script>
if(window.navigator.appName.toLowerCase().indexOf("netscape")!=-1){ // set object for Netscape:
     document.getElementById('dvObjectHolder').innerHTML = " <object ID='appletTest1' classid=\"java:test.class\"" +

<BR>
<input value="Javascript to java" type=button onClick="document.appletTest1.fromJavaScript()">

I tried this example using the repy given to an earlier post.
But its not working with me.
What i did in addition was adding plugin.jar to classpath to import netscape.javascript.*;
Let me add some more details
1) I'll add the stack trace
2) my java progrma
3) batch file to sign the applet.
1) This is the stack trace i don't know whether u will undertand this

[Bug ID 4711700|http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4711700] is eerily similar to what you're experiencing. Although the bug was reported against an older version of the JDK the last comment provides a workaround to the problem that may be helpful. Good luck.

Cannot launch Java Report Panel

I would like to use the 'Advanced' Web Intelligence editor.
Unfortunately, when I attempt to edit a WI report, I get a message that reads 'This software has already been installed on your computer. Would you like to reinstall it?'
If I allow the installation, Java 6, Update 3 is downloaded and installed. I restart the browser. Attempting to edit the WI report generates the installation message.
If I don't allow the installation, I get an error that reads 'Cannot launch Java Report Panel, please make sure you have installed a Java virtual machine.'.
It never gets out of this installation loop.
At one point, the Advance editor worked, then something changed.
The Java Control Panel indicates that I have JRE versions 1.6.0_03 and 1.6.0._20 installed (in the Java Applet Runtime Settings). In addition, versions 1.4.2_04, 1.4.2_07, 1.4.2_12, and 1.6.0_03 are listed in the JNLP Runtime settings.
Any assistance is greatly appreciated.
Craig Buchanan

I am having the same problem and I don't see an answer here. I have uninstalled every instance of java and restarted my computer, then installed the one suggested here: Cannot launch Java Report Panel, please make sure you have installed a Java virtual machine. (the Java Virtual Machine was a link). Restarted again, tried again, same error. On the sun page, I tested my java installation and it works fine. I have checked that java is enabled in both IE and Firefox and I still get this error in either browser. I am using Windows XP.
Upon comparing my computer with my coworker's java configurations, we found that she has a certificate called "Business Objects America" and I don't have that. Could that be the problem, and if so, where can I get that certificate? There was no active X question as I would have expected to see asking to run active X or not. I can't find any certificate downloads on your site at all.
Please advise ASAP because I need to use this Web Intelligence Reporting and I cannot get in.
Thank you.

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.

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?

when my applet tries to parse an XML file with SAX (no DTD-validation) i got the following error:
java.lang.ClassFormatError: <HTML> (Bad magic number)
Well i had some problems before with the ClassFormatError but they were because some class-files were corrupt. They were easy to fix because the defecitve class-file was written next to java.lang.ClassFormatError. This time i got the <HTML> expression next to the error. what does this mean?
thnx in advance!
marc

Bad magic Number. means the first 4 bytes did not equals CAFEBABE (0xCAFEBABE) But why do you see <HTML> after that is beyound me. Can you locate which class is foul and replace it?

I am having problems with my java scrip and html, I don't know if it was me or not?

java scrip was downloaded but I cant open anything with java, also my html is not reading write. I am not sure if I did something with the plug ins or add on. Oh ya I am running on a mac with mountain lion.
