Replacing servlet.jar

I need to upgrade the javax.servlet to the current version.
Is it simply a matter of replacing the servlet.jar file and reloading or is it more complicated than that ?

I am facing the same difficulty! I downloaded the TomCat added to the project path in JDev. I'm still having JDev recognizing getAttribute() and setAttribute() methods.

Download the jakarta-servletapi file, extract into a directory and add to classpath. This will cater for the command line compiles.
For JDev put the newly extracted servlet.jar on top of the one in the JDEV hierarchy ..\jswdk-1.01\servlet.jar if i remember correctly. This will BREAK servlet debugging from within the IDE - but at least you can compile and deploy.

ABOUT Servlet.jar

I need Help to Configure JBOSS IN eclipse

Hi TCz28,
Some files and dir's aren't unpacked until Tomcat is run for the first time.
The startup error is very strange, I don't know the solution for that.
The servlet.jar-error comes from the classpath (which doesn't). On NT it works a little different, but on Win'95 your must add SET CLASSPATH=.; %TOMCAT_HOME%\LIB\SERVLET.JAR to your autoexec.bat. The dir %tomcat_home% is mentioned in the Tomcat-docs, but you can replace it with c:\java\jakarta-tomcat-x.x.x-lib, for instance.
Good luck!

Some problems with servlet.jar and tomcat 4.1.27

Hello everybody,
I used to work with tomcat 3.3.1 and i've decided to use tomcat 4.1.27 now. The manual explains that we have to change de version of servlet.jar, it's done with servlet-2.3.jar but on tomcat starting i have this message:
jar not loaded. See servlet spec [...]. Offending class: javax/servlet/Servlet.class
what can i do, i've red all de documentation and i think all versions a OK??
thanks per advance
antoine

I am running Tomcat 4.1.18, so your configuration may be slightly different. I found the Servlet.class file you are missing residing in the Tomcat/common/lib directory in the Servlet.jar file. Check your path and also make sure your Servlet.jar file contains the missing class.

Error compilng servlet - even after including servlet.jar in classpath

What is javax.servlet.jar?

Servlet.jar problem

Hi all
Could anyone help me out this problem, I keep trying to figure it out these days but I still cant find my way.
I cannot compile a simple HelloWorldServlet.java, as it gave me 6 errors:
===========================================
package javax.servlet does not exist
import javax.servlet/*;
^
package javax.servlet.http does not exist
import javax.servlet.http/*;
^
the other 4 errors also pointing to the HttpServlet, HttpServletRequest, HttpServletResponse and ServletException
===========================================
I have installed Tomcat 4.1.24 and j2sdk1.4.1_01 on my computer. I know the compiler javac needs the servlet.jar when compiling servlet source code, so I have set the path like this
PATH C:\WINDOWS;C:\WINDOWS\COMMAND;C:\J2SDK1.4.1_01\BIN;C:\Program Files\Apache Group\Tomcat 4.1\common\lib\servlet.jar
However, same errors are still generated after I set the path. So can anyone can tell me what thing goes wrong with my setting? or this is not the servlet.jar and path problem?
With uncountable thank : )
Kelvin

Hi,
My questions are the same.
But I have also set up the classpath for the servlet component.
After that, I found I can't call user-defined obecjts in my servlet.
Even when I just write a simple Java command-line progarm which call the outside objects, it also can't find the user-defined objects; unless I move out the setup of CLASSPATH. So does anyone have the further solution? or tell me where I can find the answer!
Thank you so much!

No, it means you have a null reference in your JSP page.

Servlet.jar not in jdk 1.3.1?

I've always added servlet.jar into the classpath when compiling servlets and it worked fine until i upgraded to jdk1.3 which dosent come with a servlet.jar and cant find javax.servlet classes normally- so what do i have to do then besides finding my old servlet.jar file? what are the javax.servlet classes hidden in for jdk13?

You can download the J2EE add-on to the JDK1.3.
That will have the javax.servlet

Compiling file with servlet.jar

Hi,
I can compile my file under the arm/pdm package fine by using this command:
javac -classpath .;.. pdm\FileName.java
but now i wrote a servlet which imports the javax.servlet directory.
So in order for the class to compile i have to give it the path of the servlet.jar file which is in this directory: c:/jdk1.3.1_07/lib/servlet.jar
The problem am having is that i can't give both the classpaths at one time in order to compile my servlet which also uses classes in the pdm directory and also from a different directory under arm.
Please help
Thanks

Perhaps
javac -classpath .;..;c:\jdk1.3.1_07\lib\servlet.jar pdm\FileName.java

Location of SunServer7 Servlet.jar file?

Hello All I have AppServer7 development edition installed on my machine and I'm trying to compile a simple helloworld servlet to test my installation, but I can't seem to find servlet.jar in the AppServer7 directory structure. Any ideas which file has the servlet interfaces?
Thanks,
Coop

The forum for AppServer questions is:
http://swforum.sun.com/jive/forum.jspa?forumID=114
Having said that, did you check under server_root/jwsdp/common/lib directory?
Thanks

Where is servlet.jar?

Dear Forum,
I try to develop custom tag library under JDeveloper 9.0.3.2 (build 1145). When I create tld file and try to add a tag by clicking the right mouse button no popup window apears.
When i try to compile my old custom tag java classes classes from package javax.servlet.jsp.tagext can not be accesses though JSP Runtime and Servlet Runtime libraries are included in project's classpath.
The Servlet Runtime libraray has servlet.jar entry in [JDevHome]\j2ee\home\lib directory though no servjet.jar file can be not even in that library but also in all subdirectories of [JDevHome]
Where is servlet.jar?
Oh please, make it apear :)
Than You in advance.
Justinas

Look under common/lib in the %CATALINA_HOME% (%TOMCAT_HOME%).
Also the servlet classes can be in the j2ee.jar file.

Looking for servlet.jar

I've loaded a project into Eclipse that requires servlet.jar. This apparently doesn't come with the current version of Tomcat or Sun Application Server. How can I get the file and if I get an older version, is it going to work with Tomcat 5.5?

Addes servlet.jar but still doesn't compile

I'm building a servlet and therefor I added the servlet.jar file in my java/lib directory. After changing the classpath (adding the path to the lib directory), my servlet still doesn't compile. What could be wrong?
debeumers

to add a jar to the classpath, you must add the full path to the jar, for example java/lib/servlet.jar
