Cannot compile servlet

I have this in my classpath
set classpath=.e:/tomcat/Tomcat-5/common/lib/servlet-api.jar;.e:/tomcat/Tomcat-5/common/lib/jsp-api.jar
but I still get those errors saying import java.servlet.*; error
let me know what could be worng
as

You seem to have ".e:\" (ie DOT e:\) twice in your classpath
You want DOT as a classpath directory in its own right
Try this maybe
set classpath/T=.;e:/tomcat/Tomcat-5/common/lib/servlet-api.jar;e:/tomcatomcat-5/common/lib/jsp-api.jar
What are you using to compile the servlets with?
With the command line try including the classpath as an argument:
ie javac -classpath .;e:/tomcat/Tomcat-5/common/lib/servlet-api.jar;e:/tomcatomcat-5/common/lib/jsp-api.jar *.java
If you are using an IDE like Eclipse/Netbeans, you need to look at your project settings to set the library path.

Cannot compile servlet file

I cannot compile Servlet files on my WinXP environment.
my servlet.jar file is located at
c:\tomcat\jakarta-tomcat-3.3.1\common\lib\servlet.jar
what shall I do?
The error messages are only for servlet portion of code?

In XP you can set the path by rightclicking on my computer - then go to environment vairables and edit the path but I cannot see any for classpath???
What is the easist way yo use the class path?

Did you put the servlet.jar in your classpath?

Not Able to compile Servlet from ?

Hi All,

Getting error in compiling servlet

there are 6 error almost same not resolve servlet or http. I already add jdk1.3.1 and tomcat in my path I don't understand why I am getting this error please help me.

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

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.

Wrapper cannot find servlet class error

Hi all!
I'm receiving a mysterious error when I try to run my web ap. "Wrapper cannot find servlet class com.ruffalocody.report.ReportServlet or a class it depends on"
I'm running it on JBoss 3.2.7, and I have another web ap, made almost identical to this one which does not display the same error/exception.
If anyone could give me advice on what I should do to fix this, I'd very much appreciate it. :)

I'm curious. Could you strip off the "java." part of the package, so both in your sourcefile as in the directory structure? It may be that the java package is not allowed, but then I wouldn't know why you didn't get a compile error...

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:

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.

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.

Cannot Compile. Pls. help!

I cannot compile the following program which calls for another 6 class files from its code. Please note the main program (DiveLog.java)+the other 6 class files are stored in the same directory.
And also as this involves "package" I tried to compile it as "javac -classpath DiveLog.jav". But I still get the 'cannot resolve symbol' error messages.
DiveLog.java (Main Program)
package DiveLog;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class DiveLog
private JFrame dlframe; //Not assigned yet.
private JTabbedPane tabbedPane; //Not assigned yet.
//Begins Constructor
public DiveLog()
// Create a frame object to add the application GUI components to.
dlframe = new JFrame("A Java(TM) Technology Dive Log");
// Closes from title bar and from menu
dlframe.addWindowListener(new WindowAdapter()
public void windowClosing(WindowEvent e)
System.exit(0);
// Tabbed pane with panels for Jcomponents
// Instantiate JTabbedPane with keyword new
tabbedPane = new JTabbedPane(SwingConstants.LEFT);
// Calls method to set color
tabbedPane.setBackground(Color.blue);
tabbedPane.setForeground(Color.white);
populateTabbedPane();
//Calls the method that builds the menu
buildMenu();
dlframe.getContentPane().add(tabbedPane);
dlframe.pack();
dlframe.setSize(765, 690);
dlframe.setBackground(Color.white);
dlframe.setVisible(true);
}// Ends Constructor
private void populateTabbedPane()
// Create tabs with titles
tabbedPane.addTab("Welcome", null, new Welcome(), "Welcome to the Dive Log");
tabbedPane.addTab("Diver Data", null, new Diver(), "Click here to enter diver data");
tabbedPane.addTab("Log Dives", null, new Dives(),
"Click here to enter dives");
tabbedPane.addTab("Statistics", null, new Statistics(),
"Click here to calculate" + " dive statistics");
tabbedPane.addTab("Favorite Web Site", null, new Website(),
"Click here to see a web site");
tabbedPane.addTab("Resources", null, new Resources(),
"Click here to see a list of resources");
} //Ends populateTabbedPane method
// Method header
private void buildMenu()
// Instantiates JMenuBar, JMenu,
// and JMenuItem.
JMenuBar mb = new JMenuBar();
JMenu menu = new JMenu("File");
JMenuItem item = new JMenuItem("Exit");
//Closes the application from the Exit menu item.
item.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
System.exit(0);
} // Closes actionPerformed method
}); // Closes addActionListener method
//Adds the item to the menu object
menu.add(item);
//Adds the menu object with item onto the menu bar
mb.add(menu);
//Sets the menu bar in the frame
dlframe.setJMenuBar(mb);
} //Ends buildMenu method
public static void main(String[] args)
DiveLog dl = new DiveLog();
} //Ends Class
===========================================
Welcome.class (one of the 6 class files.The other 5 are identical to this.)
package divelog;
* This class creates the content on the
* Welcome tabbed pane in the Dive Log
* application.
* @version 1.0
//import for buttons, labels, and images
import javax.swing.*;
//import for layout manager
import java.awt.*;
public class Welcome extends JPanel
{ //Opens class
}//Closes class
=========================================================

Might be a typo when you posted, but your DiveLog class is in package DiveLog, whereas your Welcome class is in package divelog (note the capitalization differences).
And even though they're in the same package, i'm always a fan of importing all the files you're going to need explicitly, such as
import divelog.Welcome
this applies to using the wildcard character too (as in, you shouldn't) to import files. Explicitly listing all imports allows you, and any other developer, to quickly see a list of all classes used.

Cannot compile body of dbms_utility without its specification

hi there!
I just got this error on my 11g EE database
yesterday had power problems, and the backup batery did not work(but it happens very often)
today, trying to send email with a job, i realized through TOAD that sys has 304 invalid objects.
Try to compile and it seems something missing.
"cannot compile body of dbms_utility without its specification"
I cant find that specification and no forums found related to this.
need help from experts..
