problem with javac and http

[dognobbler]

I recently had to reformat my hard drive and I am trying to rebuild an application. I had the actuall webapps part of the application backed up but not the rest of tomcat.

So I have download tomcat and installed tomcat and copied across the webapp.

Now when I try to javac one of my servlets I get the following error:

package javax.servlet does not exist

I thought this package was automatically installed as part of tomcat.

Can anyone explain to me why I might be getting this error and what I need to do to get rid of it.

Many thanks.

You do not have the jar file containing the package javax.servlet & its sub-packages ...

You either get it in the J2EE API (in j2ee.jar), or also it comes with tomcat, usually named servlet.jar in tomcat 4 & below, or servlet-api.jar in tomcat 5. It can be found in : TOMCAT_HOME/common/lib.

OK I have checked and I do have a file called servlet.jar in directory TOMCAT_HOME/common/lib but I am still not able to javac.

Can you think of a reason why javac cannot seem to find this file when I run it.

Could this be something to do with setting the environment variables for tomcat and Java SDK. Here is what I set:

USER VARIABLES

CATALINA_HOME
C:\tomcat

JAVA_HOME
C:\j2sdk1.4.2_05

SYSTEM VARIABLES

Path
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\j2sdk1.4.2_05\bin

When I said "You do not have the jar file containing the package javax.servlet & its sub-packages ...", I meant you do not have it in your CLASSPATH - this is why javac cannot find the packages.

before compilation type :

set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\common\lib

Hi Sedj, thanks for the help but I tried that and it didn't make any difference.

Did you try :

set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\common\lib\servlet-api.jar

or

set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\common\lib\servlet.jar

?

You must nam jar files by name, not just directory (its not like the -I switch in gcc)

Thanks I did that and it worked. However now I get the following errors even though my MyBeans does exist in the webapp. Any ideas why it cannot import MyBeans?

C:\tomcat\webapps\

http://www.popmates.com\WEB-INF\classes>javac

profilePost.java
profilePost.java:11: package MyBeans does not exist
import MyBeans.memberBean;
^
profilePost.java:12: package MyBeans does not exist
import MyBeans.dbBean;
^
profilePost.java:56: package MyBeans does not exist
MyBeans.memberBean validMember = (MyBeans.memberBean) session.getAttri
bute("validMemberID");
^
profilePost.java:56: package MyBeans does not exist
MyBeans.memberBean validMember = (MyBeans.memberBean) session.getAttri
bute("validMemberID");
^
profilePost.java:110: package MyBeans does not exist
MyBeans.dbBean db = new MyBeans.dbBean();
^

MyBeans.dbBean db = new MyBeans.dbBean();
