Jsp files error....

[qiu zhixiong]

I have 2 questions:
1)
When i javac a java file, the following errors came out.
C:\>javac logon.java
logon.java:3: package javax.servlet does not exist
import javax.servlet.*;
^
logon.java:4: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
2 errors
Anyone knows what does it means??? Any ways to solve this error??
2)
When i type http://localhost:8080/cdlist/cd_list.jsp at the IE address to view the file , the following error came out
org.apache.jasper.JasperException: This absolute uri (http://jakarta.apache.org/taglibs/xtags-1.0) cannot be resolved in either web.xml or the jar files deployed with this application
Can anyone please explain what it means and is there any ways to solve this error. Thankyou very much....

To answer your first question, servlet.jar is not in your CLASSPATH and hence the error.
For second one, more info. is needed.
I would check the following:
-Is tomcat installed properly ?
-Does anything(Simple.html) work under the newly created context root.

Thanks for your reply.
1)
Some people give me this solution
javac logon.java -classpath c:\jakarta-tomcat-4.1.18\common\lib\servlet.jar
but it cant works.
2)
Tomcat works fine, the version i install is 4.1.18.
I did change the context:
<Context path="/examples" docBase="examples" debug="0"
reloadable="true" crossContext="true">
<!---- my context here -->
<Context path="/cdlist"
docBase="c:\jsp\cdlist\"
crossContext="false"
debug="9"
reloadable="true" >
</Context>
<!---- my context here -->
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_examples_log." suffix=".txt" timestamp="true"/>
If i put the cdlist folder outside root then will i need to change the context isit?? If i put the folder in root then i will not need to change anything right???
Not very sure isit 100% correct, cos it can't works. I have been tying to solve this problem for quite afew days already and i can't carry on with my project unless i solve this error. Hope you could help me, Thanks alot.

Check where is your servlet.jar is located.
And in the command prompt set the classpath:
for instance if it is in C:\Program Files\Apache Tomcat 4.0\common\lib\servlets.jar
set classpath=%classpath%;C:\Program Files\Apache Tomcat 4.0\common\lib\servlets.jar;

and then try
javac logon.java
