Jsp:plugin minimalist

Hello
I have a context "demo" with a class, "demoApplet", in a package AppletDemo and I am unclear/unable to configure the jsp:plugin. I can do the following, which doesnt work, grin.
<jsp:plugin type="applet" code="demoApplet.class" codebase="http://localhost:8083/demo/WEB-INF/class/AppletDemo" jreversion="1.4.2"> </jsp:plugin>
What is the minimal correct config necessary to launch the applet? tia.

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.

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

    My JSP is something like that:

    tokenizeName() returns the first token: alice

    When I test the applet in the IDE, it returns the values properly, but not in the JSP invokation.

    javascript will not be executing on the server. You can rule that one out.
    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.

    I would say put in a couple more alerts - one before the call to the applet, one after.
    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"

  • Expressions not evaluating properly in jsp:plugin tag

    Hi there, running OC4J as Oracle9iAS (1.0.2.2.1)
    In the JSP1.1 spec dynamic expressions in the jsp:plugin <param> tag are clearly specified as below:
    <jsp:params>
    [ <jsp:param name="parameterName" value="{parameterValue | <%= expression %>}" /> ]+ </jsp:params>
    Unfortunately, attempting this in OC4J, the expression is simply displayed as a static String, for example the following JSP source:
         <jsp:params>
              <jsp:param name="rootSubAssembly" value="<%=rootSubAssembly%>" />
         </jsp:params>
    Would output "<%=rootSubAssembly%>" as the parameter value, rather than the dynamic value specified in the JSP above.
    Any ideas? We'd like to benefit from using the plugin tag over object/applet if at all possible.

  • 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

  • How to use jsp:plugin action with type = bean

    Hi everybody,
    I'm new to JSP so it could be a stupid question but I'm wondering how can I use a jsp:plugin action with a type equal to "bean".
    Everyone is talking about type equal to applet so the browser can display this applet but if the type will be a bean so then
    does it mean I can send a javaBean class to the client?
    If yes, then can the javaBean object be executed on a client machine?
    Or maybe I'm wrong. I don't know how it works.
    Please give me a resolution.
    Thanks,
    Rafal.

  • 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 seems broken on WL 8.1

              Hi.
              I've tried using the <jsp:plugin> tag in a JSP page, conforming to Sun's JSP
              1.2 spec. It works alright with Tomcat, but it fails on WL8.1: the tag is passed
              as is into the resulting HTML.
              After hours of investigations, it seems that the WL server only transforms correctly
              the <jsp:plugin> tag, as long as there is no nested JSP syntax in it. However,
              the JSP 1.2 spec explicitely states that some parts of the <jsp:plugin> tag can
              be JSP expressions of the form <%=xxx%>. It is allowed, for instance, in the height
              and width attributes, and as applet attribute values in <jsp:param>.
              Is it a known problem? I have found no reference to this limitation in any BEA
              documentation.

  • 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,

  • JSP:Plugin and naming an applet

    Howdy,

    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

    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 in page fragment

    Would like to include an applet in a page fragment, however JSC is not happy.
    Create a page fragment, add a
    jsp: plugin tag and jsc complains with the error:
    The prefix "jsp" for element "jsp: plugin" is not bound.
    Have tried setting this plugin inside a panel grid and also within the div itself.
    So - how do I include a jsp : plugin in a page fragement?
    Thanks

  • 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.
