Jsp:plugin and codebase

I have a JSP with the following jsp:plugin code:
<jsp:plugin type="applet"
code="com.package.Applet.class"
codebase="/application1/applets/" width="50"
height="50">
</jsp:plugin>
Web applications, which run this applet, specify different codebase, such as /application2/applets/,
/application3/applets/ and so on.
Unfortunatelly JSP specification doesn't allow dynamic codebase in jsp:plugin and we create a new JSP for
each new web domain to specify another hardcoded codebase attribute.
Could you please advice a trick to generate codebase attribute at run-time, to deploy the same JSP in all
applications.

Well, then I would just put in the object/embed tags yourself. You can get whatever the plugin tag writes by just using the tag once with static values and view the source in the browser and copy it out, then replace whatever values with scriptlets (or other taglib tags) to fill in the correct values.

Path Pronlem with jsp:plugin 's codebase

I am unable to call my JApplet Class with <jsp:plugin> tag in my JSP Page. I have tried almost every combination for codebase (absolute and relative paths ) but still there is an Error ClassNotFound .
Please tell me the right way to call the Applet in JSP.
along with a small example ...
Jsp and the Class File exists in Different directories in My Web Project.

JSP:Plugin and naming an applet

Howdy,
I am presently having good success with the jsp:plugin tag starting my applet.
But, I can not seem to give the applet an ID or NAME in the <object> or <embed> tag.
This is needed, as I am attempting to access the applet from javascript in the html page.
my jsp:plugin tag looks like this:
<jsp:plugin type="applet"
          code="Pi_saa/Plugin"
          codebase="/lms1/classes"
          name="AACPlugin"
          archive="/lms1/classes/Plugin.jar"
          height="100" width="100">
<jsp:params>
<jsp:param name="org.omg.CORBA.ORBSingletonClass" value="org.jacorb.orb.ORBSingleton"/>
<jsp:param name="org.omg.CORBA.ORBClass" value="org.jacorb.orb.ORB"/>
<jsp:param name="JacorbProxyServerURL"

<jsp:param name="MAYSCRIPT" value="TRUE"/>
</jsp:params>

If you fight your way through this, you can see that there is no ID or NAME for these tags. That means I cannot access the applet from javascript.
Can anyone give me some help?
Thanks
Mark

Cant you just use
document.applets[0]
if you have just an applet in your page....
You can either use the name or an index as u do for any document property

Jsp:plugin and jreversion

Is jreversion in jsp:plugin really checked?
          I tried it with jreversion="21.31" to test it but nothing happens.
          If I specify 1.3 but the user only has 1.4 installed, does it still work?

How to deploy a JSP with jsp:plugin with applet type?

Hi,
I am a new comer for JSP and when to try to a simple JSP with plugin for applet. Following is part of my JSP script:
<jsp:plugin type="applet" code="DigitalClock" align="center" height="25" width="300"
>
     <jsp:params>
          <jsp:param name="language" value="<%=request.getLocale().getLanguage()%>" />
          <jsp:param name="country" value="<%=request.getLocale().getCountry()%>" />
          <jsp:param name="bgcolor" value="FFFFFF" />
          <jsp:param name="fgcolor" value="CC0066" />
     </jsp:params>
          <jsp:fallback>
          <p>Unable to start plugin.</p>
     </jsp:fallback>
</jsp:plugin>
===========
And Java plugin tell me that can't find DigitalClock class. I want to ask how to deply this JSP using deploytool.
Thanks,
Wise

Hi
It should be in such a way,
The Jsp:param is similar to PARAM used in Applet.
<jsp:plugin type="applet"
code="MyApplet.class"
width="475" height="350"
<jsp:params>
<jsp:param name = "PARAM1" value="VALUE1" />
</jsp:params>
</jsp:plugin>
jsp:fallback Element
It provides alternate text to browsers that do not Support OBJECT or EMBED. You can use this element in the same way as you provide alternate text in your applet.
<jsp:fallback>
<b> Error: This example requires java </b>
</jsp:fallback>
</jsp:plugin>
I hope this will help you.
Thanks

JSP Plugin tag for applets with codebase - WLS 6.1 sp2

          Could someone please tell me what I am doing wrong?
          I have the following Plugin tag in my JSP.
          <jsp:plugin type="applet"
          code="com.xxx.efm.frontend.view.EFMApplet"
          codebase="/lib"
          archive="applets/EFMFrontend.jar, EfmCommon.jar, TrimmedWeblogic.jar, dom4j-full.jar,
          /classes/"
          jreversion="1.3"
          nspluginurl="http://java.sun.com/products/plugin/1.3/plugin-install.html"
          iepluginurl="http://java.sun.com/products/plugin/1.3/jinstall-131-win32.cab">
               <jsp:params>
                    <jsp:param name="Delimiter" value="<%=delimiter%>" />
                    <jsp:param name="ComponentMap" value="<%=componentMapValues%>" />
                    <jsp:param name="ServerConfig" value="<%=serverConfigValues%>" />
                    <jsp:param name="GUIConfig" value="<%=guiConfigValues%>" />
               </jsp:params>
          </jsp:plugin>
          I am trying to load the JSP using Netscape 4.7. When I don't have a plug-in installed
          the page
          displays "Click here to get the plugin". On clicking on it the browser pops up
          a "Plugin not loaded" dialog.
          All this is fine except that the dialog says it can retrieve the plugin from "/lib".
          When I click on
          "Get the plugin" button the new browser window tries to load the URL: http://localhost:2002/lib/?application/x-java-applet;version=1.3.
          It totally ignores the netscape URL for plugin. Something similar happens with
          IE as well.
          I tried the same JSP without the codebase tag and all worked fine (except for
          my applets). Yeah, I can append a "/lib" to each of
          my jars in my archive and it just might work. But should I be doing anything different?.
          Any help is appreciated.
          Thanks,
          Gopal

Jsp:plugin codebase problem

suppose the applet class is in
TOMCAT_HOME/webapps/myapp/WEB-INF/classes/mypackage/applet.class
what the corresponding codebase for the jsp:plugin should be?
Thanks

The WEB-INF/lib and WEB-INF/classes directories are off limits cannot be referenced.
You must create and use another directory (I usually use jars) in your application's context to supply the applet.

Question concerning Eclipse and Tomcat Plugin and JSP

I have a Tomcat-Project that I am working on in Eclipse and quite a few external JARs. Everything works fine, when I run my Test class within my project (in Eclipse). But as soon, as I am trying to call the jsp in my browser I get Exceptions: "java.lang.NoClassDefFoundError: org/apache/log4j/Logger" for example, which tells me that in the browser it can't find the JARs... I'm guessing something's wrong with the classpath but I was thinking that Eclipse would handle those things for me...
I've added the JARs to my project via Eclipse (Properties -> Java Build Path -> Libraries -> Add external JARs). And I've created a subdirectory for my jsp files and allowed my project to update the .xml file for the settings and all... Do I need to do anything else? What have I done wrong so far, have I forgotten to do?

I solved the problem...

How can I return some values from an applet invoked by jsp:plugin tag

My JSP is something like that:
<html>
     <head>
             <title> . . . </title>
     </head>
     <script>
          function getValueFromApplet()
               var src = document.pinApplet.checkPin();
               document.myForm.j_username.value = document.pinApplet.tokenizeName(src);
               alert(document.myForm.j_username.value);
               document.myForm.j_password.value = document.pinApplet.tokenizePassword(src);
               alert(document.myForm.j_password.value);
     </script>
        <body>
                <jsp:plugin type="applet"
                      code="PinApplet.class"
                   codebase="/idp"
                   name="pinApplet"
                            width="300"
                            height="300">
                     <jsp:fallback> Authentication Form is not supported by the browser </jsp:fallback>
          </jsp:plugin>
                <form action="https://xxx.xxx.xxx"
               name="myForm"
               method="post" onSubmit="return getValueFromApplet()">
          <table>
               <td><input type="submit" value="OK" >
               <td><input type="hidden" id="j_username" name="j_username" value=""></td>
               <td><input type="hidden" id="j_password" name="j_password" value=""></td>
          </table>
          </form>
     </body>checkPin() returns "alice--alice"
tokenizeName() returns the first token: alice
tokenizePassword() returns the second token: alice
When I test the applet in the IDE, it returns the values properly, but not in the JSP invokation.

Is your Applet being initialised correctly?
Where have you got the classes for it? I think the applet doesn't need any kind of initialization, because it doesn't have any variables and all the process is made in the method called by onsubmit()
The applet is composed only by one class and I'm totally sure that the class is placed in the correct place.

put some logging statements in your applet to see if it gets there.In the javascript, there are two alerts between the three calls to the applet. Where do you advise me to put more alerts?
I don't understand what do you refer when you say "logging statements"
I am going to test again the call to the applet in order to find some kind of code that can be invalid or that can make the function to "crash"

Can't get jsp:plugin to work with jb5

I am trying to get a Swing applet compiled with JDK 1.3.1 to run on a jsp page using the <jsp:plugin> tag. At this stage it is a ridiculously simple applet (just some JLabels and JTextFields) but I can't get it to work. Here is the jsp code:
<jsp:plugin type="applet" code="nz.astarte.ganttapplet.GanttApplet"
codebase="./WEB-INF/classes" jreversion="1.3.1"
width="400" height="175">
<jsp:fallback>
Plugin support could not be determined
</jsp:fallback>
</jsp:plugin>
When I run it in the jb5 ide nothing shows up at all. OK, I figured the ide doesn't support the plugin, so leaving the ide running (which provides me with a web server) I go into IE (version 5) and enter the url to the page, which is http://localhost:8080/AppletCommunications/GanttApplet.jsp
I get the page, and the gray box saying loading the applet but the plugin console tells me:
load: class nz.astarte.ganttapplet.GanttApplet not found.
java.lang.ClassNotFoundException: java.io.FileNotFoundException: http://localhost:8080/AppletCommunications/WEB-INF/classes/nz/astarte/ganttapplet/GanttApplet.class
Why not? Under the directory where the jsp page is located is the directory structure WEB-INF/classes/nz/astarte/ganttapplet and in that directory is a GanttApplet.class file.
I cannot understand why it isn't found. Do applets work with the jb5 ide? Is there something blindingly obvious that I've missed?
Thanks, Andrew

I appear to have solved it, but it is not clear to me why.
I created a jar file of the required classes, and placed it in the same directory as the jsp file. My jsp code then looked like:
<jsp:plugin type="applet" code="nz.astarte.ganttapplet.GanttApplet"
codebase="."
archive="GanttApplet.jar"
jreversion="1.3.1"
width="400" height="175">
<jsp:fallback>
Plugin support could not be determined
</jsp:fallback>
</jsp:plugin>
This works fine. However I would expect to be able to move the jar file to some other directory, so that the jar file and jsp files are separated. I spent hours trying to work out why it wouldn't work when I had the jar
file in WEB-INF/classes (under the jsp file directory) and had codebase="WEB-INF/classes/". In the end I put the jar file into a directory I defined separately called wotnot and defined codebase="wotnot/"
Now it works. However I still think I should be able to have the jar file anywhere, including WEB-INF/classes and would love for someone to tell me why not!
Thanks, Andrew

Jsp plugin

I have created a jsp page and inserted an applet using jsp plugin.
the location of the jsp is C:\JDEV\testapp\test_project\public_html
and the location of the applet class is C:\JDEV\testapp\test_project\classes\test_project.
How can I supply the codebase information during plugin as' \ ' is treated as escape character.
How can I bind an applet with an action button of a jsp page?
Thanks

You need to place the class files needed to run your applet in some browser-accessible location. The WEB-INF/classes is not one of those client-accessible directories.
Think of the way you store your images on the server. Same concept here.

Jsp:plugin problem

hi,
i am using jsp:plugin to handle applets.when i am placing the applet class file in the same jsp files directory itself its working.but,when i am placing the applet class file in the WEB-INF/classes directory it couldn't point the class file and its not working.here is the tag,
<jsp:plugin type="applet" code="SampleAppletExample" codebase="WEB-INF/classes" height="400" width="500">
</jsp:plugin>
what is the problem with the tag.how can i pont the class file from jsp:plugin tag.
any one knows please help me.
regards,
j.mouli

Hi,
Please check your codebase parameter again. That part of the directory (web-inf\classes is not visible to client i.e he cann't access it. By default the classes stored under web-inf\classes directory can be accessed from the jsp.
Please find the extract from apache site related to this.
"WEB-INF/classes/ - This directory contains any Java class files (and associated resources) required for your application, including both servlet and non-servlet classes, that are not combined into JAR files. If your classes are organized into Java packages, you must reflect this in the directory hierarchy under WEB-INF/classes/. For example, a Java class named com.mycompany.mypackage.MyServlet would need to be stored in a file named WEB-INF/classes/com/mycompany/mypackage/MyServlet.class.
For further information on this, please browse through the 'Standard Directory Layout' section at http://jakarta.apache.org/tomcat/tomcat-3.3-doc/appdev/deployment.html
Hope this helps.
Good Luck.

Jsp:plugin jreversion1.4 - tomcat4.1.10 - how do I do this?

I would like to get Tomcat 4.1.10 to recognize jreversion's other than 1.2.2 when using the jsp:plugin tag.
<b>My setup:</b>
Windows XP Professional
Tomcat 4.1.10
JDK 1.4.0_01
I wrote a cheezy applet that just displays "Helloworld"
and works fine in a simple page with just a simple applet tag.
I have a short JSP page with the following plugin line:
<code>
<jsp:plugin type="applet" code="forgetech.web.ForgeApplet" codebase="." archive="ForgeApplet.jar" height="100" width="200" jreversion="1.4.1">
<jsp:fallback>
<b> JRE 1.4.1 could not be installed. </b>
</jsp:fallback>
</jsp:plugin>
</code>
The page works fine for all machines that already have a JVM.
But
On a Windows 2000 Professional box w/ IE6 and no Sun JVM; when
I navigate to the page it tries to download and install the 1.2.2 plugin. I want it to download the latest JRE instead. How can I get Tomcat to recognize 1.4 (or soon 1.4.1) and download the appropriate JRE? I tried looking through some of the config files looking for some kind of mapping but did not see anything.
I know I can use the <b>nspluginurl</b> and <b>iepluginurl</b>, but I really dont like hardcoding links into my code.
As a bonus; is there a way to fill in jsp:plugin jreversion attribute with a JNDI lookup. This would be nice so that I can set all of my JSP's on my Tomcat server to push the latest and greatest JRE with their applets.
Thanx in advance,
- Chris

<jsp:plugin type="applet" code="forgetech.web.ForgeApplet" codebase="." archive="ForgeApplet.jar" height="100" width="200" jreversion="1.4.1">
<jsp:fallback>
<b> JRE 1.4.1 could not be installed. </b>
</jsp:fallback>
</jsp:plugin>The page works fine for all machines that already have a JVM.
But
On a Windows 2000 Professional box w/ IE6 and no Sun JVM; when
I navigate to the page it tries to download and install the 1.2.2 plugin. I want it to download the latest JRE instead. How can I get Tomcat to recognize 1.4 (or soon 1.4.1) and download the appropriate JRE? I tried looking through some of the config files looking for some kind of mapping but did not see anything.
I know I can use the nspluginurl and iepluginurl, but I really dont like hardcoding links into my code.
As a bonus; is there a way to fill in jsp:plugin jreversion attribute with a JNDI lookup. This would be nice so that I can set all of my JSP's on my Tomcat server to push the latest and greatest JRE with their applets.
Thanx in advance,

Is Tomcat 4's jsp:plugin tag hardwired to 1.2?

Is Tomcat 4's <jsp:plugin > tag hardwired to version 1.2 of the JPI?
I was absolutely horrified today at a job interview when, proudly navigating to the page containing the 1.4-demanding applet I embedded in the page using <jsp:plugin ...> the plugin installation dialogue came up -- asking whether they wanted to install the 1.2 plugin (up until recently, I had the applet's object tag embedded manually... switching to jsp:plugin was fairly recent).
As it turns out, the <object> tag generated by Tomcat was specifying the download path for the 1.2 plugin, even though I specified jreversion="1.4" in the <jsp:plugin> tag:
<OBJECT
   classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
   name="theApplet"
   width="550"
   height="400"
   align="middle"
   codebase="http://java.sun.com/products/plugin/1.2.2/jinstall-1_2_2-win.cab#Version=1,2,2,0">The "clsid" value can be changed in web.xml by changing the jsp servlet's "ieClassId" initParam, but as far as I can tell there's NO mechanism for changing the "codebase" value anywhere.
Is the <jsp:plugin> tag (under Tomcat 4, at least) just useless for Applets that must have 1.4, or is there a configuration parameter somewhere to set the "codebase" value generated by the tag?
I know I could always put the manually-specified code back in, but I'd prefer to stay with the <jsp:plugin> tag if possible just because it makes the jsp source cleaner. What's strange is that nobody seems to have complained about that problem on the usual places (Usenet/dejanews/Google, jguru.com, etc). Whether that's just because nobody writes applets that actually demand 1.4, or whether everybody who does just embeds the <object> tag manually, I'm not sure.
In any case, I'm trying to figure out how to make <jsp:plugin> generate the right HTML for 1.4-using applets... or whether it's even possible.

Sigh. I found it. It's actually specified as the "iepluginurl" property of the <jsp:plugin> tag.
<emotion:frustration variation="anger">
Now I just need to figure out what *$%!# value to use for it.
The JPI's developer guide has to be the worst document I've ever seen from Sun. Normally, Sun's documents are good. Often, exceptionally so. But the JPI guide... well, after reading http://java.sun.com/j2se/1.4.1/docs/guide/plugin/developer_guide/using_tags.html multiple times, I'm still not sure what #$%^&* URL corresponds to "The newest released JPI equal to or newer than 1.4.0". The only URL on the whole page that they even imply works is hardwired to 1.4.0, and in the same breath they imply that every other codebase URL on the page is wrong, hypothetical, and shouldn't be used... oh, and for that matter, the 1.4_0 one shouldn't really be used ether, because it might change in the future. Grrrrr.
If there's a pattern to the following URLs (all used on the same page) that's supposed to illustrate something besides abyssmally bad editing and apparent indecision, I haven't seen it yet:
http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1,4,0,0
http://java.sun.com/products/plugin/1.4/jinstall-14-win32.cab#Version=1,4,0,mn
http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1,4,1,mn
http://java.sun.com/products/plugin/autodl/jinstall-1_4_0-win.cabHmmm. Let's see here. They're all the same up to http://java.sun.com/products/plugin, but from that point one diverges into /1.4/, while the others continue into /autodl/. But even past that point, two imply that the filename follows the pattern jinstall-1_4-windows-i586.cab#Version=1,4,x,* ... but whether developers who really, truly, don't care about the specific maintenance release should use "0" or "mn" is left up in the air.
Furthermore, the ONE URL on the entire page that they come halfway close to implying will work is the last one I listed above, which itself goes totally against whatever hypthetical pattern they were trying to imply with the other three. For now I'll probably stick the last one listed as the parameter because it's the only one they actually come out and say will work, but I suspect the first one is probably the "right" one.
Of course, there's always the matter of Macintosh users running IE. Or Windows users running Mozilla (which is technically Netscape, but uses MSIE ActiveX plugins). Does Mozilla get fed the value of "iepluginurl", or the value of "nspluginurl"? Sigh.
