Please Urgent sound applet in jsp problem

Hi please any body hekp me urgently.
I have a problem while playing a sound applet in the jsp file the error is class not found.
My applet class file is in the com.mypack.common
its code is
public class PlayErrorSoundApplet extends Applet
public PlayErrorSoundApplet()
public void init()
public void playSound()
String soundObj = getParameter("soundObj");
AudioClip sound = getAudioClip(getDocumentBase(), "success.wav");
sound.play();
in the jsp i have written the code like this
<applet codebase="com.mypack.common" code="PlayErrorSoundApplet.class" name="soundApplet" width="0" height="0">
<param name="soundObj" value="error.wav">
</applet>
In the applet console i got class not found error.
please help me .....advanced thanks......

actually, codbase is a directory. so
<applet codebase="com/mypack/common" code="PlayErrorSoundApplet.class" name="soundApplet" width="0" height="0">
<param name="soundObj" value="error.wav">
</applet>this means you have something like
pacakge com.mypack.common
public class PlayErrorSoundApplet {
Make sure to put the html file in the root directory of the package structure
/myhtmlfile.html
   /com
      /mypack
           /common
                PlayErrorSoundApplet.class

in index.jsp page i have included the following code for calling this applet:
<jsp:plugin type="applet" code="NewJApplet.class" codebase="applets"
width="600" height="300">
<jsp:fallback>Could not load applet...</jsp:fallback>
</jsp:plugin>
if i view it in using AppletViewer it runs perfectly and display the data in JLabel. (ie, both jlblTitle and jlblNewTitle).(ie, DATA FETCHES FROM db AND DISPLAYS PROPERLY)
BUT IF I CLICK ON INDEX.JSP, ONLY jlblTitle APPEARS. jlblnNewTitle WILL BE BLANK(this label name is supposed to fetch from database)
EVERY THING IS DISPAYING PROPERLY EXCEPT DATA FROM DATABASE!!!
i signed the applet as follows :
grant {
permission java.security.AllPermission;
Can any body help me to figure out the problem?

can any body help me regarding this matter.? Thx in Advance.

Including applets in JSP - problem!!

I'll begin by admitting that I am fairly new to JSP. That said, I am experiencing a ClassNotFoundException when trying to include an applet in a JSP under certain conditions. Here's the detail:
I'm using Tomcat 4.0.4 and am working in the default ROOT webapp directory. This is running on Win2k Pro on port 8080. I HAVE managed to get the applet to load under the following circumstances:
- JSP page in ROOT/jsp directory
- applet class file (and supporting classes) ALSO in ROOT/jsp directory
That's just great... but I want to be able to place the applet class file and supporting classes with all of the other class files in ROOT/WEB-INF/classes. Here's the scenario that fails time and time again:
- JSP page in ROOT/jsp directory
- applet class file (and supporting classes) in ROOT/WEB-INF/classes
- in this scenario I have added a 'codebase' attribute to the applet tag (please be aware that I have tried this with both the APPLET tag and the jsp:plugin tag, each method yielding identical results)
- I have tried several different codebase values, all listed below:
codebase="../WEB-INF/classes/"
codebase="http://localhost:8080/servlet/"
codebase="http://localhost:8080/WEB-INF/classes/"
codebase="."
and I have tried it w/o a codebase at all
None of these help the JSP to find the applet class file. I've really thrown my hands up in the air with this. I realize that every 3rd or 4th thread is typically a beginner with some Class not found error... but I've put my time in on this one, and I cannot figure it out. Thanks.

Hi, Ben
You bring up a very good issue that a lot of these books about JSPs and Servlets usually forget to mention.
I dont know what sort of Web Servlet Container you are using, but I know that in Tomcat there is a 'lib' and and 'classes' directory, so if you want to have classes that are used by different applications from different directories then you can place them there. If you want you can compile all these classes into a jar and put that jar either in the 'TOMCAT_HOME/lib' or 'TOMCAT_HOME/common/lib' directories or you can simply put all the .class files into either the 'TOMCAT_HOME/classes' or 'TOMCAT_HOME/common/classes' directories. This way your classes will be known to any applications running on your webserver.
If, however, you want supporting classes to be only used by servlets or jsps, then you should put them in the web-inf directory.
Let me know if this works,
Val.

Applets in Jsp generates ClassNotFoundException

hi there,
I face a problem of calling applets in Jsp.
The code to call applet is:
<jsp:plugin type="applet"
code="core.TextApplet"
width="475" height="350">
</jsp:plugin>
And I have a 'core' directory in source packages and TextApplet.java in core directory.Wehn I run the TextAppletJSP ,it gives me an error message in applet display area:
Exception:java.lang.ClassNotFoundException:core.TextApplet
Anyone who help me for this problem plz.
thanks for your help.

I am also getting out of memory errors, and Tomcat keeps increasing in memory on every page refresh. Please let me know if you get this resolved how you did it. Thanks.

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.
Hope these help you.

Premiere Pro 2.0 and Windows 7 - Direct Sound Input soundcard driver problem

My XP machine crashed, I reinstalled Premiere Pro 2.0 with Windows 7, and I got the following error: 'The Currently installed soundcard driver does not support Direct Sound Input. Recording audio is not possible.' The soundcard drivers are updated. Any ideas? Here's what I have: AMD Phenom II X4 965 Processor 3.40 GHz 8 GB, 64 bit. Thank you for looking.

Thanks! Though I upgraded to solve the problem, this is good to know.

Insert Micropone or any jack in Micropone Input or Aux Input, on your sound card or motherboard !
AND NOW YOU CAN USE PREMIERE PRO 2.0

This code doesn't seems working with Tomcat 5.5.12. I works fine with Tomcat 4.1.31
Please help
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">
     <jsp:fallback>
          <B>Unable to start plugin!</B>
     </jsp:fallback>
</jsp:plugin>cheers,
