Javax.servlet ERROR

Hello I new in jsp!!!
I'm compiling a basic jsp project for run on tomcat. The compiler send me and error message javax.servlet does not exist and it's because I only jave instaled the j2sdk. (I think)
What the library that a must download from java to succelfully compil it.
Thanks a lot and sorry for my english.
Diego

If you have Tomcat, then you have the javax.servlet library, and you just need to include it in your classpath at compile time.
It will be in the [tomcat]/common/lib/ directory
Basically if you have -
Tomcat4, the jar you need servlet.jar
Tomcat 5: you need servlet-api.jar and jsp-api.jar
Check out this useful page on setting up Tomcat: http://www.coreservlets.com/Apache-Tomcat-Tutorial/ - specifically the bit on setting your classpath.
Note this only applies to compiling your own servlets. JSPs are automatically compiled by Tomcat.
Cheers,

I never used DynaActionForm, what I have noticed here is, don't you need to declare the form bean? I may be wrong.
<form-beans>
<form-bean name="newProdForm" type="com.package.form.NewProdForm"></form-bean>
</form-beans>

Thanks for the reply buddy...
As per your reply....I have tried modifying my Preparedstatement properly with ? and then binding values...
But even after doing this i am still getting the same error....
I am clueless...
Following is my modified Prepared Statement ::
conn.prepareStatement(("Insert into MGX (BTS_ID,MGX_Num,Port_No,FRSM_No,RPM_Card,Multi_Link,Port_Status) values (?,?,?,?,?,?,?)"));
stmt1.setInt(1,Integer.parseInt(request.getParameter("bts1")));

stmt1.setInt(5,Integer.parseInt(request.getParameter("allocRpmNo")));
stmt1.setInt(6,Integer.parseInt(request.getParameter("allocMultiLinkNo")));
stmt1.setString(7,"Allocated");
Awaiting for a solution....

Error:    package javax.servlet.http does not exist

How do I import javax.servlet?

Hi,
The file servlet-api.jar / servlet.jar is not available in your classpath.
To compile an Servlet you need the jar file to be in classpath.
The jar file can be found in your webserver / application server lib folder.

ANT script genrated error: package javax.servlet does not exist

Hi there,
I am running ANT and confronted this message:
    [javac] Compiling 1 source file to C:\eclipseProjects\tomcat_test
    [javac] C:\eclipseProjects\tomcat_test\WEB-INF\src\WebTest.java:4: package javax.servlet does not exist
    [javac] import javax.servlet.ServletException;
    [javac] ^I googled around and found this solution:
servlet-api.jar is the jarfile that contains javax.servlet.ServletException and javax.servlet.http.* which are imported by WebTest.java and must therefore be found in the classpath. If javac doesn't find this jar (or the javax.servlet packages), it will say (or shout, depending on my and javac's mood): [the error message]
well...I set in the classpath the location of the servlet-api.jar
(found at: C:\Tomcat\common\lib)
I set it with the environment variable (windows xp)
Just as it's shown here: http://www.cs.usask.ca/~wew036/latex/env-env.jpg
NOTHING :-(
could anyone assist, thanks

Hi..seems u r new to J2ee.. dont worry its a very small problem:
Here is the solution.. yes u have to edit the environment variables:..
I am using J2EE sdk 1.4 and running on xp
This is the classpath setting:
C:\Sun\AppServer\lib\j2ee.jar;
This is the PATH setting
C:\Sun\AppServer\bin;
Good Luck :)

Javax.servlet.* Not Found Error - Please help

I am having a great deal deal of trouble trying to compile a program using javax.servlet and javax.servlet.hhtp.*. I have setup the JAVA_HOME and the CLASSPATH variables as per the Installation instructions. I appear to have hit a brick wall and I am absolutely desperate to get this working. I have installed the J2EE SDK as well as the Servletapi2.1. Please Help.
Variables:
CLASSPATH=c:\jdk1.3\lib\tools.jar;c:\j2sdkee1.3.1\lib\j2ee.jar;c:\jdk1.3\jre\bin;c:\jdk1.3\jre\lib;c:\mm.mysql-2.0.14\org;c:\jdk1.3\lib\servlet.jar;
JAVA_HOME=c:\jdk1.3;
J2EE_HOME=c:\j2sdkee1.3.1;
PATH=%PATH%;c:\jdk1.3\bin;c:\j2sdkee1.3.1\bin;
Error message from compiler:
L:\PROGRA~1\allaire\jrun\servers\default\loanstest\web-inf\classes\PasswordServlet.java:27: package javax.servlet does not exist

public class PasswordServlet extends HttpServlet

I can only think of three suggestions.
One, use your mouse to "cut-n-paste" the value of CLASSPATH and verify that those files are exactly where you think they are, and are spelled right.
E.g.
CD C:\JDK1.3\LIB
DIR SERVLET.JAR
Two, if they're spelled right, run "jar tvf" on the files to make sure they aren't corrupted or something.
E.g.:
JAR TVF SERVLET.JAR
Three, since you're working in Windoze, try putting the value inside double quotes. E.g.:
SET CLASSPATH="c:\jdk1.3\lib\tools.jar;c:\j2sdkee1 ... etc ... "
If you haven't tried the above, give it a go, see what happens.

servlet.jar is not in your classpath. You should not get this error once you include this in your classpath.

Javax.servlet.http.* error

I am trying to compile a file, but got the error message "package javax.servlet.http does not exist",
"import javax.servlet.http.*"
It seems to me that this particular package is missing. how and where exactlly do I get this particular package and make it to work??
thanks

As you are using the package I assume that you're targetting a servlet engine (such as Tomcat) or a J2EE server. The package is in servlet.jar which is part of the binary release of the container that you are using.
You can download containers from the following links:
http://java.sun.com/products/servlet/index.html
http://jakarta.apache.org/tomcat/index.html

Import javax.servlet.* gives error "package does not exist"

I am working through Monica Pawlan's book "Essentials of Java PL".
My PC runs Windows2000 prof. I have downloaded and installed j2sdk-1_3_1_01-win.exe in c:\jdk1.3.1_01
I have downloaded and installed tomcat4.0 (jakarta-tomcat-4.0.zip) into c:\jakarta-tomcat-4.0
CATALINA_HOME is set to c:\jakarta-tomcat-4.0 and CLASSPATH is set to .;C:\jakarta-tomcat-4.0\common\lib\servlet.jar
I can compile an applet starting:
import java.awt.Color;
import java.awt.BorderLayout;
import java.awt.event.*;
import javax.swing.*;
//Class Declaration
class SwingUI extends JFrame implements ActionListener { ... }
but trying to compile my servlet starting:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ExampServlet extends HttpServlet { ... }
gives me the error (import javax.servlet.*) "package does not exist".
Any pointers on this immediate problem? and is my book out of date?
Many thanks,
James Towell

You downloaded the Java 2 SDK Standard Edition, but you need to also download the Enterprise Edition if you want to write programs that use enterprise features.

Error in importing javax.servlet.ServletConfig;

Hi
I am fairly new to servlets technology
while importing package javax.servlet.ServletConfig; i got error Create class "ServletConfig" in package javax.servlet
I'm using eclipse IDE

Which project have you created in eclipse?
Java or J2EE project?
If its a J2EE project, the jars will be included automatically in the lib
but if its a Java project, you will have to include the servlet-api.jar in the classpath.

Missing artifact javax.servlet.jsp:jsp.api:jar:2.1 Eclipse error

When I try to UPDATE my Maven project ( Chapter 8 - Using JSP with AEM 6.0 ) after I updated my main pom.xml with the javax.servlet.jsp dependancy, I get the following error :Missing artifact javax.servlet.jsp:jsp.api:jar:2.1
I even tried to compile from command line using mvn compile and get the same error :

If I look at my .m2 dir, I can see that it attempted to get the jar, but it wasn't able to grab it :

Hi Billy,
Try changing the URL from (http://repo.adobe.com/nexus/content/groups/public/) to (https://repo.adobe.com/nexus/content/groups/public/), i.e. add the https.
That should do it. Let us know if it doesn't work.

Not sure which workflow tutorial you are reffering. The stack trace in log should tell you what is exactly wrong.

Error:java.lang.NoSuchMethodError:javax.servlet.jsp.tagext.TagAttributeInfo

Hi All,
I am getting the following error when i create a jsf jsp page and build it in jdeveloper.
Error:java.lang.NoSuchMethodError:javax.servlet.jsp.tagext.TagAttributeInfo.<init>(Ljava/lang/String;ZLjava/lang/String;ZZ)V
when i build the application by simply creating jsp not jsf jsp then it works well.
Could you any tell me how to fix this? i searched in forums but i didn't find relevant solution.
Thanks,
Udhaya

Hi!
Can you tell us what version of JDeveloper you are using, and what steps you took to create the JSF page? Like, write from scratch or use the JSF page wizard?
Also, can you check your project properties, and check that the JSF libraries are included, and JSF tag libraries set up?
