you not set the classpath for your web server... which web server you using to support your servlet files ?.

set the classpath for your webserver, your errors will be rectified.

Looks like you are missing the servlet-api.jar. Possibly other jars as well.

[preethi Ayyappan]

Thanks gopi sri .I am using tomcat webserver.It is in the path /usr/local.How should i set the path for this and where i have to set the path?

arulk,
I am having the servlet-api,servlet jar files in /usr/local/apache-tomcat/common/lib and also in /usr/java/jdk/bin and also in /usr/java/jdk/jre/bin. what else i have to add in which path?

Preethi If you want to compile your servlet
then set classpath to the servlet-api.jar
and then compile , Your compilation problem will be solved
Bye

[gopi sri]

hello preethi....
oh great you are using good web server..you set the classpath for your web server using servlet-api.jar file.

goto->mycomputer->rightclick->properties->press Advance tab-> click EnvironmentVariables-> window open

you should enter following
variable name : classpath
variable value: D:\apache-tomcat-6.0.14\lib\servlet-api.jar;
OR
/usr/local/apache-tomcat/common/lib\servlet-api.jar;

i given D:\apache .. since i have apache tomacat in D: drive !! you enter the path where you apached is located..

tak care,
gopi

If it is present at multiple places then anyone can do, but make sure you dont run into version problems.I'll say add /usr/local/apache-tomcat/common/lib to your classpath.
More on compiling servlets here .
BTW gopi sri, preethi is using Linux and not Windows

Hi preethi Ayyappan,

set classpath for each jar files separatly.

the Tomcat or java compiler wont take if you specify the path till lib.

classpath in environment varable: "C:\Tomcat 6.0\lib\servlet-api.jar"

Thanks & Regards,

I am having problem even in accessing the servler-examples project which is given in default.When i tried to access the tomcat page i can able to view that page.But when i tried to access http://192.168.1.147:8080/servlets-examples,i am getting the following error:

HTTP Status 404 - /servlets-examples

type Status report

message /servlets-examples

description The requested resource (/servlets-examples) is not available.
Apache Tomcat/5.5.26

why it happens.It is also due to any class path problem or tomcat is not installed properly?

[Vijay Jeyam]

Make sure that your TOMCAT,Catalina and Java home are set correctly.

If possible use ANT/maven scripts to compile and deply your application

[preethi Ayyappan]

Thank you all.I have solved the problem by compiling it like
javac -cp servlet-api.jar:servlet.jar:mysql-connector-java-3.0.17-ga-bin.jar:.:asterisk-java-0.3.1.jar Outbound.java.

Now it compiles well. but tomcat projects are not opened and displaying error
