Calling applets in jsp

Hi All,
When I tried to call an applet in my JSP page ,it says like " java plugin not installed properly"...I don't know what is wrong with my installation.I'm using jswdk server.
Could anyone help me please....
Would Appreciate if I get help.

Hi
A plugin is used as a substitute to the browser VM as somtimes the client browsers may not have the right version of the VM to run some components like Swing etc.
The way you handle this in JSPs is that you use the <jsp:plugin> option . Any good tutorial on JSps will give you information on this.
One place to start would be:
The <jsp:plugin> directive takes care of generating all the HTML code necessary to embed and activate a Java applet. Consider the following example:
<html>
<head>
</head>
<body>
<jsp:plugin type="applet" code="NewsTicker.class" name="newsticker"
height="100" width="100">
<jsp:params>
<jsp:param name="x" value="10"/>
<jsp:param name="y" value="25"/>
<jsp:param name="cx" value="90"/>
<jsp:param name="cy" value="114"/>
<jsp:param name="bgcolor" value="102,102,153"/>
<jsp:param name="textcolor" value="0,0,0"/>
<jsp:param name="hilitecolor" value="255,0,0"/>
</jsp:params>
<jsp:fallback>Oops! Something bad happened and I can't display this
applet</jsp:fallback>
</jsp:plugin>
</body>
</html>
The code above sets up the applet contained in "NewsTicker.class", and passes it a bunch of name-value pairs of parameters. The <jsp:param> tag is used to pass these
parameters to the applet, while the <jsp:fallback> directive contains error text, in the event that the applet cannot be found or displayed.
When JSP compiles and renders the page, the code above is automatically converted to its HTML equivalent.
<html>
<head>
</head>
<body>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" width="100"

The above sample was taken from the two links shown below.
- http://home.netscape.com/assist/net_sites/embed_tag.html
- http://www.devshed.com/Server_Side/Jserv/JSP8/print.html
For further reading the documentation that comes along with your application server should provide ample guide to using jsp:plugin with your applets.
Good Luck!

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

make sure that you put this class in the right directory.

Passing data from Applet to JSP and back

What is the best way for me to communicate between an Applet and a jsp page? I want to be able to call Applet methods from the JSP and be able to send data to the JSP from the Applet. Thanks.

Can't do this
JSP lives on the server. When it's done, the code is sent to the client
So, in terms of lifespan...
JSP -> Internet -> Client -> Applet
JSP is dead before applet starts

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

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

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>

Hi,
Though there are a lot of importing parameters, you should give only one structure for outtable, and read as index 1 and index 2.
FORM GET_SPRAS TABLES intable   STRUCTURE itcsy
                                          outtable STRUCTURE itcsy.
DATA: lv_kunnr LIKE kna1-kunnr.
CLEAR: GV_SPRAS.
lv_kunnr = intable-value.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      input = lv_kunnr
    IMPORTING
      output = lv_kunnr.
SELECT SINGLE LAND1 SPRAS INTO (gv_land1, gv_spras) FROM KNA1
    WHERE KUNNR = lv_kunnr.
IF sy-subrc = 0.
    READ TABLE outtable INDEX 1.
    outtable-value = gv_spras.
    MODIFY outtable INDEX 1.
    READ TABLE outtable INDEX 2.
    outtable-value = gv_land1.
    MODIFY outtable INDEX 2.
ENDIF.
IF gv_land1 EQ 'DE'.
    CLEAR: GV_LAND1,
           GV_SPRAS.
ENDIF.
ENDFORM.

Error while calling applet from Javascript via LiveConnect and WebDriver

Hi all,
I am trying to call applet Java code from Javascript via WebDriver.
Given the following two cases:
- calling a static method: Integer.parseInt("42")- constructing a new object: new String("Hello world")My Javascript code looks like this:
document.appletId.Packages.java.lang.Integer.parseInt("42");
new document.appletId.Packages.java.lang.String("Hello world");When executing this code in Firefox via the Firebug Javascript console everything works fine and I get the expected results. However, when executing this code via the JavascriptExecutor from WebDriver only the call to the static method succeeds, the construction of the new object leads to the following error: "Attempt to call a default method on object with no invokeDefault method."
I don't have any idea what is going wrong here, so any help would be greatly appreciated.
Thanks!
