Embed an applet in jsp

Hi I have created an applet and put the Statistics.java into my project folder. I am using jsp for the project. I am using this code:
<APPLET code="Statistics.class" width="200" height="200">
</APPLET>
in the jsp but when I run it it just runs a grey box set to the specified size.
Anyone know why?
Any help appreciated

Use HtmlConverter and it will put converted tags for your applet coding.
It will look like this,
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
WIDTH = 780 HEIGHT = 525 codebase= ""
<PARAM NAME = CODE VALUE = "">
<PARAM NAME = CODEBASE VALUE = "">
<PARAM NAME = ARCHIVE VALUE = "" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.2.2">
<PARAM NAME="scriptable" VALUE="false">
<NOEMBED>
</NOEMBED>
<EMBED type="application/x-java-applet;version=1.2.2" CODE = "" CODEBASE ="" ARCHIVE = "" WIDTH = "780" HEIGHT = "525"
PLUGINURL = ""
</EMBED>
</OBJECT>

Object tag is recognized by IE browser and Embed tag is for Netscape broser.
Hope it helps.

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,

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

at all.Set CODEBASE to point to the relative directory where your code is. If it is in the same directory as the JSP then CODEBASE="."; if it is in a sub-directory 'classes' then CODEBASE="classes".
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. Close ALL browser windows - you have to force the plugin JVM to re-initialise - I've not found any other way to do it.

How to run the applet in JSP

hi,

please can you help me in this matter.

And don't use the applet tag, use object embed.
use the htmlconverter in the jdk bin dir to convert an applet tag.

Well instead of generating entire applet ,you can have a generic applet which takes parameters as ( <PARAM name="name" value="value"> ) inputs and process those inputs to generate output.
In this case the output of the stand alone program would be a object. And in JSP page you need to access this object, then you can get the values which need to be passed to Applet.
Else
1.Identify the real path of the applet class file
ServletContext context = session.getServletContext();
String realContextPath = context.getRealPath(request.getContextPath());2.Copy the file to a standard location in your web application

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>

</jsp:plugin>
and I copy the class file to folder where the JSP page is located. When I start Jsp page I have a message: "Applet not found"
What I do wrong??? PLZ Help!
BEST REGARDS

Hi,
I am not sure the JSP file, which resides in the public_html directory, is part of the class path of the running application. If you open the project properties, you can see where JDeveloper looks for Java classes. Try and extend this setting to include the public_hml directory (you can also try and just add the source as a library path (see library section))

Embed an applet into jpanel

I have a unique problem. I have an application built on swing f/w with xml used for design and maven used for build.
I have an applet that is independent of this application. Now i dont have a clue how to embed that applet into a jpanel or into that application. Anything of that will help me immensely. Please suggest if anybody has a clue.
Thanks in advance.

In any case, if you control the source of the applet, or can recreate it, the best solution has already been given on the first reply.
If not, and it actually makes sense to embed an Applet or JApplet in a Swing JPanel(/JFrame), then it becomes more complicated.
Here is one of the most simplistic [examples of embedding an applet in a JFrame|http://forums.sun.com/thread.jspa?messageID=10259860#10259860]. If it becomes necessary to pass parameters to the applet, allow it to share input streams, or implment the showStatus() showDocument() methods as I did in Appleteer, it becomes more complex again. So far I have found no practical way to mimic Applet/JavaScript interaction.
Edit 1:
And noting you are yet another multi-poster. No that is not unique, just very irritating, and a great disincentive for others to help.

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...
