Applet in JSP/HTML

hi:
i have a myWebApp deployed in Tomcat\webapps, which contains:
myWebApp
- home.html
- WEB-INF
--- classes
------ applet1.class
what are the code should be in home.html to load applet1 ?
i tried:
<APPLET CODE="applet1.class" codebase="\WEB-INF\classes" WIDTH=200 HEIGHT=200></APPLET>
but not work.
please help. thank you in advance.

I always put my class or jar file in the same directory as the html file where codebase="." works just fine. Why don't you try:
<APPLET CODE="applet1.class" codebase="./WEB-INF/classes/" WIDTH=200 HEIGHT=200></APPLET>
or
<APPLET CODE="applet1.class" codebase="./WEB-INF/classes/." WIDTH=200 HEIGHT=200></APPLET>

JSP applet tag X Html applet tag (what is the difference?)

what is the advantage in using the JSP applet tag instead of a simple Html applet tag ?
second question:
I have an applet in a Html frame, and a menu on the left side.... When the user select the applet option at first time, everything runs ok.. after the user select another option and then select the applet again, it fails in some features .. Why ?

well, if by "the JSP applet tag", you mean the jsp:plugin tag.. that will just generate the same HTML tag you would write. The only advantage would be it should be less typing to use the taglib.
second answer:
without seeing any code, it'd be hard to figure out the problem. The obvious thing is you are setting some state of something that is preventing further action.

Applet in JSP Unable to run.. help!

Hello all... am running Lomboz Eclipse on WinXP .. all current versions and runtimes of relative java and tomcat updated and my web apps are all working as expected with no real problems... EXCEPT that I am unable to get a simple applet to display in a jsp page. I am using the <jsp:plugin > tag and the cosole gives me that dreaded bloody class not found error. I can run the applet
in appletviewer (from inside the ide) no problem. I have tried placing the applet in a html page then using <jsp:include> but alas that seems to lock up my whole system. I remember several years there was a tool called the sun applet plug in converter... not sure to be honest.. I am no expert in web apps by any means...so my plight may just be class file in the wrong dir.. or some other arcane issue with classpath.... and help would be appreciated!

Re: Including Applet in JSP with Dynamic input| Help needed

Hi All,
We are into a project in Oracle Portal Server where in we want to embed a result of a standalone application in Portal page.
We can do that once we can embed the result of the standalone application which generates applet based on the input it gets from the current application's database.
If it was static we could have used jsp:plugin but, it fails in our case!
We are clueless as to how to embed an applet which will pick up the data dynamically.
Can anyone of you help me in this regard?
Thanks & Regards
Arthi

Hi Arthi,
I think this might help you to get an idea why jsp:plugin tag does not allow for dynamically called applets.
<jsp:plugin type=applet height="100%" width="100%"
archive="myjarfile.jar,myotherjar.jar"
codebase="/applets"
code="com.foo.MyApplet" >
<jsp:params>
<jsp:param name="enableDebug" value="true" />
</jsp:params>
<jsp:fallback>
Your browser does not support applets.
</jsp:fallback>
</jsp:plugin>
The plugin example illustrates a <html> uniform way of embedding applets in a web page. Before the advent of the <OBJECT> tag, there was no common way of embedding applets. This tag is poorly designed and hopefully future specs will allow for dynamic attributes (height="${param.height}", code="${chart}", etc) and dynamic parameters. Currently, the jsp:plugin tag does not allow for dynamically called applets. For example, if you have a charting applet that requires the data points to be passed in as parameters, you can't use jsp:params unless the number of data points are constant. You can't, for example, loop through a ResultSet to create the jsp:param tags. You have to hand code each jsp:param tag. Each of those jsp:param tags however can have a dynamic name and a dynamic value.
I think you can get better information if you look in to the below link

Many Thanks,
Ramesh.

Applets run client side - which means the relevant class files need to be downloaded to the client.
Anything under the WEB-INF directory is not directly accessible by the client. Nothing under WEB-INF can be downloaded.
ergo, specifying the WEB-INF directory as part of your applet codebase is a bad idea.
I would suggest try copying the applet classes from under WEB-INF to some other place in your application.
Also, you should probably specify the full class name of your Applet in the plugin tag.
<%@ page import="com.util.MyApplet" %>
<jsp:plugin type="applet" code="com.util.MyApplet" codebase="/classes" width="250" height="100" jreversion="1.6">

Applets in JSP --- I'm going crazy!

I am using an applet I have written on a JSP page which I have also written.
Using: Win2K, IE6, J2SDK 1.4, Tomcat 4.0.3
I have several problems. Even if you can answer only one of them, it will be a great help!
Here is how I'm adding the applet.
<jsp:plugin type="applet" code="RawData.class" name="rawData" jreversion="1.4" width="700" height="55" >
<jsp:fallback>
Plugin tag OBJECT or EMBED not supported by browser.
</jsp:fallback>
</jsp:plugin>
</TD>
Problem 1) I can only get the applet loaded if the applet class file is in the same folder as the JSP file. Anything else, and I get a ClassNotFoundException.
Can't get the CODEBASE to do anything for me at all.
I set my codebase="/RawData/classes", but makes no difference.
I then tried Jarring my applet and placing RawData.jar in the same folder with the JSP. But also no go. I then set codebase="RawData.jar", but guess what... Nothing.
So my questions are: How do I get the applet to load from the applet.class files using codebase if the applet files are in a sub folder? And how do I get my applet to load from a Jar?
Problem 2) Once this applet is loaded, I have the biggest nightmare imaginable to get the browser to load a new version after I have updated it. And trust me, there is not and old version of the applet.class in my ClassPath. In fact there is not another copy of the applet.class file anywhere on my PC. I made sure. I have also disabled the Java Plugin Cache option, and deleted my temporary internet files with Explorer. But the thing persists in loading the old version from somewhere. What the heck do I do? I fear this is driving me insane.. :)
Problem 3) I need the HTML components to interact with the applet.
When I do a call to an applet function passing no parameters it works fine, and I get the value back, like this:
<SCRIPT LANGUAGE="VBScript">

</SCRIPT>
But when I do a function call, passing parameters, the scrip just stops working altogether, like this.
<SCRIPT LANGUAGE="VBScript">

</SCRIPT>
Why is this. What am I doing wrong.
And better yet... Is there a way of manipulating the HTML components from within JSP scriplet <% ... %>?
Please if anyone can help... It will be greatly appreciated. I am at a loss!
Thanx. Quigrim

imaginable to get the browser to load a new version after I have

Process Monitor Diagram Applet in JSP

Has anyone experienced to use Java Applet in JSP to display the process diagram, just as what you can see in the workflow console. I notice that WF_MONITOR has a getMonitorURL() API which returns a link that leads to Workflow Console, I feel this isn't user friendly. If I could bring what user exactly sees the process diagram in workflow console to Java JSP, it would be superb ...........
any idea?
Kun

All I can think of is that you are using swing and
including the necessary files via import statements in
the code. This might cause the applet to run fine with
the default Netscape JVM. On the other hand, when
using the jsp:plugin tag the browser is instructed to
download the Java2 plugin regardless of whether the
applet will run or not. What I'm saying is that you
probably don't have the Java2 plugin installed on your
browser rather you have the necessary jar files in
your classpath to support Java2. Does that make any
sense?>
CliffI don't have a shell CLASSPATH variable, and I'm not sure how to tell what CLASSPATH variable Netscape is using.
The applet doesn't use Swing as far as I can tell, the code for this applet is at
http://tmap.pmel.noaa.gov/~callahan/JAVA/map_v3.0/LiveMap_30.java.
It appears to use only awt for imaging, which I think is considered Java1.
A bit off topic:
I have the javaplugin.so which ships with jdk1.3.1_01. However when I look under Edit->Preferences->Navigator->Applications and try to set the plugin used for application/x-java-applet I see that the setting is one for "Unknown - prompt user". Also if I look under Edit->Preferences->Advanced I can see that "Enable Java" is checked and activated but "Enable Java Plugin" is not checked and unavailable (it is greyed-out).
1) How can I get Netscape to "know about" the plugin I have available in my JRE ?
2) How can I tell Netscape to use this plugin for all things Java ?
3) How is it that the applet runs fine when included in a HTML page, even though it appears that my browser's application settings aren't set up to handle applets correctly ?
4) The Netscape Edit->Preferences->Advanced shows that Java is enabled but the plugin is not. I guess I'm missing something here as I thought that the Java plugin was required for anything Java related to run (such as applets) but this is obviously not so since the applet will run fine if coming from the HTML page.
A bit perplexed...

Applet to JSP !!!

Hi all,
I am trying to make a chat application in which registered users
of the website can interact with each other through text aswell as
voice messages after they logged in the website.
There will be e.g three chat rooms in which users can enter.
After login,they can chat with each other through voice aswell as text
messages.
For the above task I am trying to develop a JSP enabled chat application in which users can communicate with each other through Applets using JSP.
I want to know how can I connect my Applet to a JSP to develop such chat application.
thanks for any help in advance:-)

Whenever I hear terms like "JSP enabled" I stop listening. That's pure marketing BS. Accordingly, your entire sentence doesn't make sense. What is the JSP supposed to do? I can't think of anything that can't be done by static HTML.

How do you make JSF draw frame in browser w/o JSP & HTML ?

Hi all,
I already have small web application which uses HTML & JSP and I want to convert it to JSF based application.
I've read O'Reilly JSF books written by Hans Bergsten and in Chapter 15 he states that you can use pure Java classes only (without JSP & HTML) in your web application.
My web application contains some frames. Since I only want to use pure Java classes using JSF what component should I use to draw frame ?
I use MyFaces implementation of JSF.
Any advice would be greatly appreciated.
Best Regards,
Setya

I don't know anything about myFaces, but as far as I know, there is no component to draw frames. The JSF book you read is correct to a degree... It's possible to write completely with JSF tags, but it can be cumbersome sometimes.
To output frame tags using a JSF tag, you can use one of two methods.
First, you can use the outputText tag with escape attribute set to false.
<h:outputText value="<FRAMESET blah blah blah>" escape="false" />The second way is to just wrap HTML in f:verbatim tags.
<f:verbatim><FRAMESET blah blah blah></f:verbatim>If using the second method, be careful not to have any other JSF tags inside the f:verbatim tags.
Hope this helps,

How can I pass a variable to an applet in JSP?

I want to invoke an Applet in JSP and pass a variable( ie. port) to the Applet. I do as follows:
<applet code="best.Applet1.class" width=400 height=300 >
<param name=port1 value=port>
</applet>
in Applet1.java , I use getParameter("port1"),yet I got character string "port" ,not the value of port(i.e. 100).
How can I get 100 not "port"? Thanks!!!

Assuming that port is a variable defined and initailized in the jsp:
<applet code="best.Applet1.class" width=400 height=300 >
<param name=port1 value=<%= port %>>
</applet>

How to convert the source code in JSP,HTML&BEANS into executable files?

Sir,
We are developing one s/w product in JSP,HTML&BEANS.Now we are in the implementation phase.During the time of Installation,without copying our source code in the customer's site I want to copy the executable files of the entire source codes? Is it possible in JSP,HTML&BEANS?

In theory you can do it even with JSP but the you will be unable to run it on the standard JSP engine. :-)
From other hand, all critical logic should be in the Java Beans or at least in custom tags but not in the JSP code. Then you can protect that code and leave JSP open because there is nothing to steal or break.

Java Applet in a HTML page: failing with PLS-00306: wrong number of args

We are trying to use a Java Applet in a HTML page. as our system needs to be able to retrieve a predefined set of data from a third party system that uses Dynamic Data Exchange Protocol (DDE) and are encountering errors from APEX and in IE itself.
We are using JavaDde from www.nevaobject.com that enables our Java applet to interact with Windows applications (Third Party System) using DDE.
This functionality is currently used in our Web Form 6i application and we are trying to use the same in the new ApEx application.
We are using ApEx version : 2.1 and actually aer encountering 2 problems:
Problem 1: ApEx failing with PLS-00306: wrong number or types of arguments in call to 'ACCEPT'
Problem 2: IE crashes if Applet used in a complex page with several regions (1 Context, 4 Report Regions, 2 level Tabs, Links)
This problem does not occur in the page where there is only applet and one region. In the case of complex page the IE crashes if the page is reloaded
Test scenario:
1- Create a simple page with the HTML region.
2- Define the Source of the above region as follows
<OBJECT CLASSID="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
CODEBASE="http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#version=1,4,0,0"
WIDTH="1"
HEIGHT="1"
ID="simpleApplet"
NAME="simpleApplet">
<PARAM NAME="code" VALUE="simpleApplet.class" >
<PARAM NAME="archive" VALUE="simpleApplet.jar" />
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.4">
</OBJECT>
3- Create a simple Java applet "simpleApplet" - for the test its enough if the applet will have just the init method printing out the mesage to the console
4- Create a Submit Button (not redirect) in Region Header and create unconditional (do not set When Button Pressed property) Page Branch to navigate to another page (the page without the applet)
6- Run the page and Submit -
The error below is returned by the engine:
In our case our applet is called ddeApplet - I do not know why is ApEx passing the Applet's ID down to the wwv_flow.accept method as a parameter
