Create problem when compiling the servlet

hi,
i got a problem when i compile a servlet
when i try to compile the servlet, it shows that it could
not found the classes like httpservlet, etc.
means the classes of the servlet
i am using the j2sdk1.4.1 edition,
i had include the javax.servlet.*; in the program
please tell me what can be the problem & especially any solution for that

the javax.servlet package and it's sub packages (javax.servlet.http, javax.servlet.jsp, javax.servlet.jsp.tagext) are not included with the Standard Edition. These packages are part of the Enterprise Edition. Check out this link for download:
http://java.sun.com/j2ee/sdk_1.3/

it's not CLASS_PATH, it's CLASSPATH.
Directory paths with spaces in them are problematic. Surround them with double quotes.
I think the best thing is not a CLASSPATH environment variable. Better to use the -classpath option on javac.exe when you compile.
So your command to compile might look something like:
javac -classpath .;"C:\Program Files\Tomcat\jakarta-tomcat-5.0.28\common\lib\servlet-api.jar" *.java%

Compiling Java Servlet with Depricated Methods

I have a problem of compiling Java servlets that contain depricated methods. If you compile against modern version of servlet.jar I see depricated methods error messages and if I use a very old servlet.jar it cannot find newer methods. What is is the best solution in this case?
Thank you,
Boris.

The best thing to do would be compile your code with the -depreciated option to find which methods have been depreciated and the refactor your code to remove them.
The next best thing is to ignore the messages (they are warnings not errors) and your code should still work

Problem in compiling servlet class - using Tomcat

Hi,
I have a servlet pgm that I'm trying to compile.I using Tomcat application server.I have my servlet class in D:\servlet_wrk\project1\src
and my deployment descriptor in D:\servlet_wrk\project1\etc
my CLASSPATH var is set to C:\Sun\AppServer\jdk\bin
and
my PATH var is set to C:\Sun\AppServer\bin.
When I compile my servlet class Ch1Servlet.java in the command line from the directory
D:\servlet_wrk\project1 using the command
javac -classpath D:\applications\tomcat-5.5.12\common\lib\servlet-api.jar -d classes src/Ch1Servlet.java,
it says error:cannot read: src/Ch1Servlet.java
Can somebody help me to solve this problem and help me to compile my servlet class.
Thanks.

Thanks...as u said I tried putting dir & found that
my file was saved as Ch1Servlet.java.txt instead for
Ch1Servlet.java......So that was a problem.Now I'm
able to compile.Oh, yeah. Notepad will do that to you. I think when you save in Notepad if you put quotes around the name "Whatever.java" then it won't add the .txt.
But on compiling I'm getting the following error
package java.servlet.* does not exist
package java.servlet.http.* does not exist
package java.io.* does not exist
Do u the reason for this??? The servlet stuff is java[b]x.servlet. For the io stuff, I don't know, I'd have to see your code. Either you have a typo or a corrupt installation.

Problems compiling a servlet

Hello,
I recently installed Tomcat 4.1.24 and I am trying to compile a servlet but with no success. The error I get is package javax.servlet does not exist. I have set up jdk1.3.1-3 and the environment paths. I have been successful in compiling regular java applications. I am currently just using the dos prompt and command line c:\javac somefile.java
When I tried to compile a servlet, I ran into the javax.servlet error so I found a javax.jar file and added it to the jdk1/3/1-3\lib directory but the compile still fails.. I even tried to add it to the environment path but that still doesn't work...
could someone tell me where I would need to add the javax.jar file? and what adjustment I need to make to be able to compile servlets?
thanks in advance for any help

You need to get J2EE (Java 2 Enterprise Edition). Download it and install it. It's basically a couple of JAR files that you need to use. Under $J2EE_HOME/lib there is a file called J2EE.jar Include that JAR file into your project and carry on with your servlet development.

Compiling a Servlet that uses JavaBean

I have a servlet that will get data from a JavaBean which is created before in a jsp file. While I trying to compile the servlet I am getting this message:
--------------------Configuration: JDK version 1.3 <Default>--------------------
Command : "C:\jdk1.3\bin\javac.exe" -d "C:\jakarta-tomcat-3.2.1\webapps\ROOT\WEB-INF\classes" C:\jakarta-tomcat-3.2.1\webapps\ROOT\WEB-INF\classes\MyServlet.java

^
2 errors
Process completed.
Where is the problem. SimpleBean is successfully being initializing in my jsp file. But I couldn't compile my servlet that will get data from that bean. Both my servlet and bean are in the same package. I am using JCreator to compile servlets. I think the problem is the compile string that JCreator uses. Can you help me. Thx in advance.

Looks like an import Problem.
The Compiler is not able to "see" the SimpleBean Class.
Take care of the Classpath and your imports.
Happy Coding. :-)

Problem with Sessions in Servlets

Hi,
I'm having a problem with sesions with servlets. It seems that if someone logs into my website, which is running on all servlets, while another person is logged on, the second person gets the session of the first person.
I'm using
HttpSession session = request.getSession(true);to get the session in each page. The session contains a user object which shows if the user is logged in and what permissions.
The session should be unique to the client computer right? Or am I jsut screwing this up big time?

Yes, each client will have their own session. However, you may be testing incorrectly:
In Firefox, for example, all instances of the application running on the same machine will share the same cookies, therefore the same session, and would be considered one client.
MS IE will do the same if you use File - New to open a new wondow rather than clicking on the desktop icon.
If the different clients are using different machines and still getting shared data, then you may be using class-level variables in the servlet, which would not be thread safe and could lead to your problems...
public class MyServlet extends HttpServlet {
String data; //bad
int moredata; //bad
public void doGet(...) ... { ... }
}

Problem with logout in servlet After logging out i need to expire the pages

I have a problem in logout using servlet.
I introduced sessions in my page and while logout i used
session.removeAttribute("name");
session.removeAttribute("password");
res.setHeader("Cache-Control","no-store"); //Directs caches not to store the page under any circumstance
     res.setDateHeader("Expires", 0); //Causes the proxy cache to see the page as "stale"
     res.setHeader("Pragma","no-cache"); //HTTP 1.0 backward compatibility
String user=(String)session.getAttribute("name");
          System.out.println(user);
          if(user==null)
               System.out.println("hi");
               req.setAttribute("Error", "Session has ended. Please login.");
               res.sendRedirect("http://localhost:8080/homepage.html");
and after i logout im redirected to login page but after clicking back button im getting back to restricted pages(the pages b4 logout).
what should i do?????

Thanks Dear BalusC,
I tried with this,
rs.getString("DATA_SCAD1")// where the source from .xls files
String pattern = "yyyy-MM-dd";
SimpleDateFormat format = new SimpleDateFormat(pattern);
try {
Date date = format.parse("DATA_SCAD1");
System.out.println(date);
} catch (ParseException e) {
e.printStackTrace();
System.out.println(format.format(new Date()));
this out put gives me Tue Apr 03 00:00:00 IST 2007
But I want to display the date format in yyyy-mm-dd.

Problem in compiling j2me file

Hello friends,
friends my problem in compiling j2me file..
when i compile my j2me file through WTK2.2 (toolkit)
then it creates extra file including j2me" .class" file..
for example if my j2me file is "aman.java" and when i compile it
then it will covert into "aman.class" file but it creates one more file like "aman1$.class" ..plz help me to get out of this problem..coz its increase my j2me file size..
thanks
Aman

That is an inner class in aman.java that you are seeing there.
If you use inner anonymous classes, for example;
public class MyMIDlet extends MIDlet {
   // code for the MIDlet
   // Anonymous inner class
   setCommandListener(new CommandListener() {
      public void commandAction(Command c, Displayable d) {
        // implementation;
        // may access MyMIDlet's private fields
}then the command listener you create will become another class named MyMIDlet$1.class.
In this example you can get rid of the inner class by making one of the existing classes implement that CommandListener interface:
public class MyMIDlet extends MIDlet implmements CommandListener {
   public void commandAction(Command c, Displayable d) {
     // implementation;
     // may access MyMIDlet's private fields
   // code for the MIDlet
   // Instead of the anonymous inner class, we can now use MyMIDlet since it
   // implements CommandListener
   setCommandListener(this);
   // etc. etc. etc.

root cause
java.lang.NoClassDefFoundError: HelloWorld (wrong name: hall/HelloWorld)Is your servlet contains first line as package hall;If it is there,remove it from the servlet code. And run your program.
If you want to keep it, then make a folder named hall in classes folder and put your HelloWorld.class there. Also change <servlet-class> as
<servlet>
    <servlet-name>HelloWorld</servlet-name>
    <servlet-class>hall.HelloWorld</servlet-class>
