Where to find javax.management.snmp package

where can i find the javax.management.snmp package? i have downloaded the java management extension (jmx) package, but the snmp package was not included.

I think you can't find the jmx snmp package because it's currently under development.

Cannot find javax.servlet package

I have just downloaded and installed the latest JEE SDK having installed Tomcat on a Linux box so that I can start getting to know JSP.
I am following an example in a book I have for this Servlet...
import javax.servlet.http.*;
import javax.servlet.*;
import java.io.IOException;
public class BasicServlet extends HttpServlet {
     public void doGet (HttpServletRequest req, HttpServletResponse res)
          throws IOException {
          ServletOutputStream out = res.getOutputStream();
          res.setContentType("text/html");
          out.println("<html><head><title>Basic Servlet</title></head>");
          out.println("<body>Hello World</body></html>");
I am using Textpad to write and compile my java and when I try to compile I get errors basically saying that it cannot find the first 2 packages I am trying to import (it manages to find the IOException fine)
Any ideas why? I suspect that the servlet package is not in the classpath but I do no know where the package is in order to add it to my class path.
many thanks

Cannot find javax.ejb.CreateException fix classpath

Hi Guys,
I have made a Webdynpro in which I am using an EJB in the libraries of the project. When I access the classes of EJB I am getting a complie time error saying
Cannot find class file for javax.ejb.CreateException. Fix the classpath then try rebuilding this project.
Can you tell me how to fix this.
Regards,
Khusro Habib

Hi,
Guys I was able to solve this problem, by adding
C:\Program Files\SAP\IDE\IDE70\eclipse\plugins\com.tssap.ext.libs.j2ee_1.3.0\lib\ejb20.jar
into the project properties>> in the Java Buildpath adding external jars.

Cannot find javax

Hi I hit 2 problem here...
1) My jbuilder got corrupted when I closed it without saving my project and I hit the following error
"Fail to start Java VM:193"
May I know how am I going to revive it back??
2) Left without any choice, I compile my java file from the jdk1.3\bin directory... and I hit this error--( basically I import javax package and I compile them in dos mode using javac.)
testAppln.java:10: package javax does not exist
import javax.*;
^
1 error
I had include those classpath that store all the javax folder but still I cannot compile successfully.....Pls help.........:((((

The rt.jar that hold all of the "standard library" classes, java... javax... Are not part of the "user" classpath. Instead, they are part of the "bootClassPath" so the users don't have to worry about it.
So basically if you can't find javax.*; for an import your installation of the JRE is messed up. You can try to set the bootClassPath to the path of rt.jar and see if this is true with the following command.
java -XbootClassPath:c:\jdk1.3\jre\lib\rt.jar MyMain
experiment with that, and see if that works. Or just reinstall :)

Cannot find javax.jws.WebService

Hello
I'm kinda new to this web service thing. I tried to run the hello program using jdk 1.5 update 5. It said it cannot find the javax.jws.WebService. Does anyone know where does this package located so I can set the environment variables? Or if anyone can give me step by step guide for setting the environment to deploy a web service it'd be greatly appreciated.
Thanks
SqW

I'm using this way...
If you installed Java 1.5, then make JRE directory like below.
%JAVA_HOME\jre\lib
C:\Program Files\Java\jre1.5.0_04\lib
Copy all JWSDP 1.6's jar file to JRE\lib\ext folder..
Then, do not pay careful attention to classpath..

Cannot find javax.servlet in J2EE

I am learning about servlet programming. I am using JBuilder-student edition. I downloaded J2EE. I changed the project properties in JBuilder to use the java.exe in J2EE, but when I try importing javax.servlet or the like, it does not show that javax has such a package. Please help. I am working on this project with a professor, and I have to show some work done soon! I cannot get started with my work unless I get javax.servlet.
I hope somebody can help me.
Thank you,

It seemed that the installation did not unzip the j2ee.WAR, which contains the servlet stuff.(or is it not supposed to?) I then added the folder j2ee to the class path, and it works. I am dumb enough not to understand how it worked, could someone explain please.
Thank you

I cannot find javax.servlet package in j2sdk-1.4.0-beta3

I just download and install j2sdk-1.4.0-beta3 and progam a very simple program use import javax.servlet.* and compile it, there is a mistake:
package javax.servlet.* does not exist
And I check the doc of j2sdk-1.4.0-beta3,I also can not find package javax.servlet.So where could I find this package? Need I configure somewhere or download another products?

Hi,
You can go to http://java.sun.com/products/servlet/download.html,
download the servlet 2.3 class files, add the zip file to the classpath.

Cannot find javax.crypto.KeyGeneratorSpi

The following code compiles but
I get a runtime error as follows.
NoClassDefFoundError for javax.crypto.KeyGeneratorSpi
I did a jar tf on the sunjce_provider.jar file and
this class is not contained?
It is in the jce1_2_1.jar file and is abstract.
When at runtime the factory tries to create an instance
of the keyGeneratorSpi I think it tries to get a concrete
implementation of the class from the SunJCE implementation and cant find it?
Is this correct.
Obviously the classpath is set correct as I am able to
import all of the SunJCE classes.
Heres the code.
import java.io.*;
import java.util.*;
import javax.crypto.*;
import javax.crypto.spec.*;
import com.sun.crypto.provider.*;
import java.security.*;
public class CryptoTest {
public static void main(String[] args)
KeyGenerator keygen = null;
SecretKey desKey = null;
Cipher desCipher = null;
Security.addProvider( new com.sun.crypto.provider.SunJCE() );
byte[] ciphertext;
try
keygen = KeyGenerator.getInstance("DES","SunJCE");
catch(Exception e){
System.out.println("Exception getting keygenerator");
e.printStackTrace();
}

What jdk version do you use?
I use the J2SDK 1.4.0-beta(contains the jce and the Sun JCE provider).
And the following code works fine to me:
KeyGenerator keygen = null;
try {
keygen = KeyGenerator.getInstance("DES","SunJCE");
} catch(Exception e) {
System.out.println("Exception getting keygenerator");
e.printStackTrace();
}

Javac cannot find javax.servlet.*; package

getting an error when I try to compile code that contains the line:
import javax.servlet.jsp.*;
import javax .servlet.*;
Yet, other classes in javax can be seen by the compiler such as javax.swing.*;

I had to download the servlet specification from sun as it wasn't in my jdk (I prefer stripped down versions). Then I placed the jar file in my classpath.
Alternatively, if you are already running tomcat you can point to the servlet api jar file in the lib directory.
And a clear indication that the person stumbling like
that shouldn't try writing servlets yet, as he
clearly lacks knowledge about what's even in the
standard API and what isn't.That's a clear indication that the person making such comments should not be on the forums as the idea is to help people and encourage people.

Cannot find javax.microedition.khronos.opengles

Hi all,
I'm relatively new to Java, and have gone through much of the tutorial. I am trying to utilize the OpenGL ES API and am unable to locate it in the latest 1.6 SDK. What am I missing here? I found documentation around the API but haven't located the API itself to save into my JDK source file. Any help would be appreciated.

oh. I think I got it. You managed to run the opengles code in emulator, right? Now, you want this code somehow to run without emulator, correct?
Well, per my understanding of the nature of "JSR 239: Java _Binding_ for the OpenGL ES API", only having API jar should not be sufficient for that.
Thing is, jsr 239 only binds java to underlying platform-specific OpenGL code. Code in jar is rather an adapter, it doesn't do the real job.
I think that in order to run opengles code without emulator, one has to figure and reproduce a way how emulator performs that binding to platform-specific code on the particular machine. If I understand correctly, there should be something outside the API jar, something that does the real thing, something passing java stuff to "real", platform-specific OpenGL.

First and most obvious question is, what are you trying to have the applet view? The NoPlayerException generally means that JMF couldn't figure out how to display what you're telling it to display, be that an unknown codec, or unknown media type.

Javax.media.NoPlayerException: Cannot find a Player for :v4l://0

Hi,
I'm trying to grab a frame in a linux box with a webcam.
First i was having trouble in getting my webcam registered but thats history and now i can use jmfstudio to view thru the camera's eye.
But using the code below to get a frame i get the following exception:
Exception in thread "main" javax.media.NoPlayerException: Cannot find a Player for :v4l://0

Any tips?

hi
i've got the same problem too
the jms could only play .mp3 not other formats
is the installation wrong?
could some experts give me some advise?
my e-mail:[email protected]

I've used the same apple ID for years and it is now saying it cannot find it. It won't allow me to log in to manage my account

So I am trying to get into manage my account on appleid.apple.com. My ultimate goal is to edit my primary email address so that I can switch it over. I no longer have access to the email address that is registerd as my apple ID. However, when I log into manage my account, it is saying it cannot find my Apple ID, and when I try to the reset password, it tells me an e-mail has been sent and to open it to verify (it will not give me the "edit e-mail for verification" option.) I am running into a load of problems. Ultimately I just want to be able to have access to my Apple ID that I have had for years but now the password can't be reset, and the apple ID can't be found. I am at a loss.

Sometimes, sites divide their content and login logic over multiple servers. In that case, the sites may not recognize that you have logged in if you block third party cookies. Can you check your cookie settings, as described in this article: [[Websites say cookies are blocked - Unblock them]].
During your earlier troubleshooting, did you try the site in Firefox's Safe Mode to rule out an extension as the potential culprit? More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using

In the dialog, click "Start in Safe Mode" (''not'' Reset)
Any difference?
