Why jar files work only in WEB-INF/classes extracted ?
Hi , The only way to make my servlets find my jar files is to extract then ans put them at WEB-INF/classes/. WEB-INF/lib/ did not work. Why? Stella -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
java.lang.NoClassDefFoundError
I've placed my servlet in the directory : $CATALINA_HOME/webapps/ROOT/WEB-INF/classes/Login.class and I've written the following at the $CATALINA_HOME/webapps/ROOT/WEB-INF/web.xml : ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd; web-app servlet servlet-name login /servlet-name servlet-class Login /servlet-class /servlet /web-app . Also, I've placed my .jar file at the directory : $CATALINA_HOME/webapps/ROOT/WEB-INF/lib/jCo.jar . When I try to reach the address http://localhost/servlet/login it seems that tomcat can't find my .jar file. I've tried a simple servlet with no specific dependencies and worked fine. Please someone tell me what to do in order to have my servlet working...

RE: Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error -HELP-ME-PLEASE
Thanx Carl,
I've placed jCO.jar at $CATALINA_HOME/common/lib/ it didn't work. I've
tried to extract it and placed the classes at
$CATALINA_HOME/common/classes/ and didn't work either. Also, I tried
$JAVA_HOME/jre/lib/ext/jCO.jar and all other possible paths but tomcat
seemed that could not find it. I worked with Apache Jserv before and the
same servlets worked fine but I want to use Tomcat now.
Any idea someone ?
So it executed the Servlet Login2 as evidence in the stacktrace
root cause
java.lang.NoClassDefFoundError
at Login2.doGet(Login2.java:51)
at
javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
... and it got all the way to line 51. It looks like there are other
classes from this jar package that are being invoked. If they are being
invoked with no exception then the jar file is found. But the class at
line
51 is not found. My line counting isn't working so you need to point
to the
source code line 51. Also assuming your classes are like this:
com.sap.mw.jco.JCO.Repository and the jco.jar file is in your WEB-INF/lib
directory.

New to Tomcat - Need Help!
Hi! I was looking for a way to have a web server running serlvets so I tried Tomcat4. I know few about xml and the configurations are written in xml. I have a lot of questions: - How can I add a directory /icons just like in apache ? - What shall I write at the web.xml of each WEB-INF directory in order to make my classes executable and available? - How can I make my own .jar files available not globaly but on certain servlets? - How can I change my directory index file from index.html to index.wml ? - How can I prevent certain paths to be available through the browser ? - How secure is Tomcat or how can I make it secure? Please help me to get started with Tomcat :-) -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
