Problem compiling servlet

I have IIS5 and Jrun and jdk1.3.1. Im trying to compile a basic servlet for the first time....
I get errors regarding the Http....here is the code.....
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
     public void doGet (HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException
          PrintWriter out = response.getWriter();
          out.println("<HTML>");
          out.println("<HEAD>");
          out.println("<TITLE>");
          out.println("An HTML Hello World");
          out.println("</TITLE>");
          out.println("</HEAD>");
          out.println("<BODY>");
          out.println("<H1>Hello World</H1>");
          out.println("</BODY>");
          out.println("</HTML>");

I didnt find the servlet.jar in the Jrun dir. I'm still a newbie obviously so any more help either of you can give would be appreciated. Thanks
BTW, the code is taken from the book JSP Weekend Crash Course, so if the code is wrong then I dont know how to fix just yet.

I have a problem compiling servlets bymeans of NetBeans IDE 3.6.

If I compile a servlet by means of another IDE, they are oK and work well with NetBeans too.
On the contrary, if I compile it bymeans of Netbeans 3.6, I get a .class which does not work. I
have realized also that for instance if the .class i get with the other IDE is 1,58 KB, if I use
NetBeans I get a .class smaller, that is 1,53 Kb.
Can you help me?
Thanks

ok
This is the servlet named Contatore.java
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Contatore extends HttpServlet
private int conta;
public void init(ServletConfig config) throws ServletException
conta = 0;
public void doGet(HttpServletRequest richiesta, HttpServletResponse risposta)
throws IOException, ServletException
conta++;
risposta.setContentType("text/html");
PrintWriter out = risposta.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Pagina con contatore</title>");
out.println("</head>");
out.println("<body>");
out.println("Questa pagina e' stata visualizzata");
out.println("<h1>"+conta+ "</h1> volte.");
out.println("</body>");
out.println("</html>");
out.close();

Having problems compiling *.java with import javax.servlet.jsp......

I've been trying to do the tutorials in a book titled Apache Jakarta-Tomcat as part of my introduction to JSP. I'm new to Java but do know the basics. I have on my machine Java 1.3, Java 1.4, Java FrameWorks 2.1 and Jython 2.1 on Win2000 Pro. So enough about my configuration. I have never worked with packages also.
I downloaded the files from the books site due to the fact I make a lot of typos when hand coding Java (I've become a pretty good debugger of my own code). But everytime I go to compile the *.java I get error messages. So below you will find HelloTag.java and beneath that the error messages that are thrown when I try and compile it. I tested other bits of *.java and have had no problem compiling them. Is there a JSP module I'm missing?
Am I doing something wrong or am I missing something from my configuration.

Well, it looks like you've not got the servlet development kit JAR on your classpath. I think it'll probably be called servlet.jar on your system. Add that to the classpath if it's not already there.
Incidentally, you've bumped into one of the areas Java's slightly lenient - declaring a method that looks like a constructor:
public HelloTag() { }
public void HelloTag() { }The first is a constructor, the second is a normal method. I'm assuming you intended to have the former instead of the latter.
Anyway, hope this helps.

Problem in Servlet Compilation & Deployment

At the time of compilation gives error message "import javax.servlet.* is not a recognize package.You have to include servlet.jar or j2ee.jar in the classpath when compiling.
My JDK is :-j2sdk1.4.2_04
My Java Enviorment is:- Version 1.5.0 (build 1.5.0_04-b05)Why are the versions of your JDK and Java runtime environment different? Why are you not using Java 5 to compile and run everything?
Class Path=C:\j2sdk1.4.2_04\lib;C:\j2sdkee1.2.1\lib\j2ee.jar;C:\JSDK2.0\libIf this is an environment variable, it should be "classpath", not "Class Path" with a space in between.

Compiling Servlet problem that uses a 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>--------------------

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.

Hi,
The problem is it is not finding the Bean. Put it in the classpath.
The simplest way is put the class in /WEB-INF/classes/MyPackage folder.

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
gjcat777

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 servlet with helper class

Hello,
I have to write a very large number of database queries and huge amount of code so I decided to make each helper *.class file for each table.
Now I have a main servlet that should instantiate each of these helper classes and conduct DB operations:
//Servlet code
RescardreservationTable rv = new RescardreservationTable();
rv.insertInfo();
RescardPassengerTable rp = new RescardPassengerTable();
rp.insertInfo();RescardreservationTable.class
//does DB opsMy problem is that when I try to compile servlet, I get
insert_data.java:172: cannot find symbol
symbol : class RescardreservationTable
location: class insert_data
RescardreservationTable rv = new RescardreservationTable();
Could somebody please tell me how I can make servlet locate my java classes that it has to use?
Thanks,
Victor.

Ok, looks like it's solved. Just forcing the compiler with -classpath to look for the required class file.

Why we need to restart server when we compile servlet (not for jsp)

hi
why we need to restart server/appln when we compile servlet .
same thing is not true for jsp
as jsp converts to servlets then also it need not require restart of server/appln.
Danny

Compile Servlet

when i try to compile servlet i got error message. it can't be identify servlet classes. why is that?
some books mention about class path to fix that problem. but i can't understand.
can any one explain little bit deep?
* i am using windows xp and tomcat server.
-thanks-

hi,
for example your tomcat in c:\tomcat5.0 means
set classpath=c:\tomcat5.0\common\lib\servlet-api.jar
or
set classpath=c:\tomcat4.1\common\lib\servlet.jar
or find servlet.jar or servlet-api.jar (thats depend upon your tomcat version)
give classpath for that jar file
and compile

Unable to compile servlet files in javac

i am unable to compile servlet *.java files in javac.as far as i can see my path is correct.
Kindly provide a solution as soon as possible.
My jdk1.3 is in my c drive and my tomcat in my d drive.
if you are able to compile kindly let me know your path.
it says symbol not resolved.i think that it is unable to import from javax

Assuming that your jdk is in c drive as c:\jdk1.3 set the path and the classpath like as shown below. Remember that you have to set the classpath for the classes in the javax.servlet and javax.servlet.http packages. I know how to do it for JavaWebServer. JavaWebServer has a jar called servlet.jar that contains all these classes. What you need to do is to put this jar file in your classpath. There will be a similar jar file for Tomcat server also. You need to refer the Tomcat server documentation for that.
The path and the classpath have to be set like this...
d:\>path=%path%;.;c:\jdk1.3\bin;
d:\>set classpath=%classpath%;.;c:\jdk1.3\lib;c:\JavaWebServer2.0\lib\servlet.jar;
assuming tht JWS is installed in c:\JavaWebServer2.0
Also note that there should be no spaces in between while setting the classpath. In your case you have to change the last part of the classpath to customize your requirement.
Hope that will help.
Regards
Jaydeep

Problems compiling Zaptel package [SOLVED-ISH]

Hey guys, I'm on an Arch64 system and I'm having problems compiling Zaptel (a dependancy for Asterisk).
Here's the pastebin of the errors I get from the Zaptel makefile: http://pastebin.com/776475
Here's my analysis so far:
There's a line in the Makefile for the zaptel driver that goes like this:
make -C /lib/modules/2.6.17-ARCH/build/ SUBDIRS=/home/woogie/zaptel/src/zaptel-1.2.8 modules
This line activates the kernel's makefile in order to build modules, but specifies that the source directory for zaptel should be included in the make process.
Then things go down the proverbial drain - linux/err_kernel_only.h gets included in the build process, which is designed to do one thing only - stop the build process. So I'm not entirely too sure what's going on here. Is there something misconfigured on my system, or is the Zaptel build system flawed somehow, such that I need to compensate for it?

Further information:
I've manually run the problematic make command from /lib/modules/2.6.17-ARCH/build on my own. After reading the kernel makefile documentation, I've learned of the V=1 flag to show me exactly what's going on. The failing command is this one:
gcc -Wp,-MD,/home/cestus/zaptel/src/zaptel-1.2.8/.zaptel.o.d -nostdinc -isystem /usr/lib/gcc/x86_64-unknown-linux-gnu/4.1.1/include -D__
KERNEL__ -Iinclude -include include/linux/autoconf.h -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -O2
-fomit-frame-pointer -m64 -mno-red-zone -mcmodel=kernel -pipe -fno-reorder-blocks -Wno-sign-compare -fno-asynchronous-unwind-tables -fun
it-at-a-time -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -Wdeclaration-after-statement -Wno-pointer-sign -I. -Iinclude -O4 -g -Wall -DBUILDING_T
ONEZONE -m64 -DSTANDALONE_ZAPATA -DZAPTEL_CONFIG="/etc/zaptel.conf" -DHOTPLUG_FIRMWARE -I/home/cestus/zaptel/src/zaptel-1.2.8//include
-I/home/cestus/zaptel/src/zaptel-1.2.8//include/oct6100api -DMODULE -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(zaptel)" -D"KBUIL
D_MODNAME=KBUILD_STR(zaptel)" -c -o /home/cestus/zaptel/src/zaptel-1.2.8/zaptel.o /home/cestus/zaptel/src/zaptel-1.2.8/zaptel.c
I've figured out that the bit which causes the failure is "-include include/linux/autoconf.h", because autoconf.h just includes the "err_kernel_only" header automatically, which then slays the build process. And I've also discovered that the Zaptel devs are uber-leet. They've found the magical -O4 level in gcc. You know, the one above 3, where the supported optimization levels in gcc are -O, -Os, -O2 and -O3

You need to add servlet.jar into the classpath. You can find servlet.jar in tomcat_home\lib dir.
