Java.lang.ClassNotFoundException:myclass org.apache.catalina.loader

I've been building some HTTP servlets and to ease up on the typing I've created a ServletUtilities file and class for repetitve tasks. I then added this file to my core package. However once I made a call to my ServletUtilites class from the other classes I've been getting:

Cannot import package org.apache.catalina in Tomcat 4.1

Hi,
Don't know why I cannot import org.apache.catalina.realm.RealmBase.*; or org.apache.catalina.*; but no problem in importing org.apache.*; ?
error prompts "package org.apache.catalina.realm.RealmBase does not exist " Thanks.
Jackie

Yes, I can find org.apache.catalina.jar in /lib but why my jsp program cannot locate this class? Something wrong with my web.xml / server.xml? Thank you.

Newbie question: taskdef class org.apache.catalina.ant.DeployTask error

Hi,
I am trying to run one of the examples in the JWS tutorial, but everytime I go "ant build" it throws the following error
<stuff_up_front>/jaxrpc/common/targets.xml:30: taskdef class org.apache.catalina.ant.DeployTask cannot be found
As far as I know I have all the necessary path and environmental variable set. Only thing I can think of is that I choose not to install the Tomcat that comes bundled with the JWSDP package since I already had tomcat server running on my machine. But my Catalina_Home has been set from a long time and it works with other applications. So I really not sure what I am suppose to do. Help would be very welcomed. Thansk you.

Please dis regard I just now noticed the dates on this thread. (I sure hope you have gotten it working by now.)
I did get these examples running. The fact that I had several versions of Tomcat installed by IDE's I think alot of my env.vars where not pointing to the proper place. I ended up just using all the stuff that came with the jwsdp(server and likes). maybe later once I get a greater understanding I can do better. BUT I AM A BIT SLOW. Thanks all.
If you every reply to me type slow so i can keep up.

Sorry, you are not running Java 5. I know you think you are, and I
don't know how to prove there is an older Java (probably 1.42) installed
somewhere). But there is
> java.lang.UnsupportedClassVersionError:
> com/novell/webaccess/WebAccessServlet (Unsupported major.minor version
> 49.0)
This error can ONLY occur if the JVM is running too old a version. As it
happens 49.0 is 5.0 (50 is 6.0, 51 is 7.0).
java -version doesn't prove much. (that proves a version of java you
have is 1.5, but not that tomcat is running it). Go to the tomcat dirs,
find the bin directory and try running startup.sh directly there. IIRC
it spits out the JAVA_HOME var it is using.

I have configured the JAVA_HOME, J2EE_HOME and J2EE_CLASSPATH correctly, as far as the documentation tells me. Would I be correct in assuming that I have a missing JAR file, if so any idea which one ?
TIA Matt

Solved my problem.
After checking the CPATH, J2EE_HOME, and JAVA_HOME and finding no problem I found a post on a website that talked about a conflict with servlet.jar in the JAVA_HOME\jre\ext folder and with other versions of Java.
So I reordered my PATH env variable and put the JDK1.3.1_01 paths at the beginning, as I have Oracle installed and Jbuilder and they have JDK's with them as well. I aslo removed several JAR's from JAVA_HOME\jre\ext (including servlet.jar)....
and eureka I can now get the congratulations page.
Not sure if Oracle or JBuilder are going to like it !!!

Use org.apache.catalina.FileLogger

Hi All,
Does any1 know of a neat way to implement the org.apache.catalina.logger.FileLogger class in a JSP ?
I have referred to a number of sites and all I got was to configure the server.xml file's Context for the org.apache.catalina.logger.FileLogger class.
But that's not what I want.
What I want is to be able to implement the logging thru JSP code so that I can write my own errors in the log file.
Any suggessions ??
Thanx.
Sherbir

Hi,
you must to try whit this
in the web.xml
<init-param>
<param-name>FileLog</param-name>
<param-value>/log/logfile.log</param-value>
</init-param>
<init-param>
<param-name>log4j-init-conf</param-name>
<param-value>log4j.properties</param-value>
</init-param>
in your class
String directory = this.getServlet().getInitParameter("FileLog");
System.out.print(directory);
System.setProperty("log.directory", directory);
String prefix = this.getServlet().getServletContext().getRealPath("/");
String file = this.getServlet().getInitParameter("log4j-init-conf");
System.out.println(prefix+file);
if(file == null|| file.trim().length()==0 ||(new File(prefix+file).isFile())){
System.out.println("ERROR: no se puede leer el archivo ");

What is: org.apache.catalina.startup.bootstrap

This keeps poping up in my dock.
"org.apache.catalina.startup.bootstrap"
Why is it there and is it a problem.
I have not noticed it there in the past four years. It is also seen at shut down.
Thank you for your help.

That would be a Java-based loader for the Catalina component of Tomcat, an extension to Apache to handle JavaServer pages. Did you or someone at some time in the past install the Tomcat server on your system?

Can anybody plz tell me how can i eliminate that error.............Thanks in advance.
Edited by: sumanthchowdary on Jun 2, 2008 11:34 PM

What is there inside your jxl.jar.
Apache POI library name is poi-3.0.2-FINAL-20080204.jar in the last release available on [http://www.apache.org/dyn/closer.cgi/poi/]. Check your classpath, IMHO it doesn't contain any POI class.

Org.apache.catalina.startup.Bootstrap

On our XServe with MacOS X Server 10.6.8 there appears in the dock 'org.apache.catalina.startup.Bootstrap'. This prevents the system from rebooting. How can we remove 'org.apache.catalina.startup.Bootstrap'?

Catalina is part of Apache Tomcat, which is a web services environment. That tool is not part of the default contents of the Dock on OS X Server 10.6, so it's been added. If you don't want it in the Dock.app, then drag it off the Dock.app. Might also want to see if Tomcat is being automatically launched during bootstrap, if you don't want that. Usual launch would be via launchd or maybe via a login item or via a web-related start-up.
Which implies there's something else going on here, or something else that's concerning you related to the OS X Server environment. Could you elaborate a little more on what's happening or the specific text of any diagnostics you're receiving?
Now if Tomcat is running and you're trying to reboot, for instance, then you'll probably want to shut down Tomcat first, or rework the shutdown to perform that shutdown automatically.
If you're intending to run Apache Tomcat and don't want that icon to appear in the Dock, then you'll want to use a command-line editor or TextWrangler text editor (do not use a GUI text editor, Office, nor the TextEdit tool, to edit this file, as these will convert the file to a format that won't be readable by the Unix environment) the catalina.properties file, and add the following configuration setting:
java.awt.headless=true
On a local 10.6 OS X Server box, here's the path to that file:
$ locate catalina.properties
/Library/Tomcat/conf/catalina.properties
$
