Re: tomcat 4.1.24 + sdk 1.4.1_03 + Win 2000
Mark, Is there a reason why you are not using startup.bat? (instead of catalina run). The configuration that you describe works like a charm for me! I did have a ClassNotFoundException when I was running Tomcat v4.0.1 (Tomcat v4.0.3, and Tomcat 4.1.24), J2SDK1.4.0_01 on W2000 (and RedHat Linux 8.0), but all this was solved when I installed J2SDK v1.4.1_03. The only thing that you do that seems to differ from my setup is that I use startup.bat and shutdown.bat instead of catalina run.

A post in the archive suggested editing out the JMX MBeans stuff in server.xml and it worked for the original poster, so if you don't need it (if you don't know what it is it is likely that you don't) so in server.xml comment out the following: !-- Uncomment these entries to enable JMX MBeans support -- Listener className=org.apache.catalina.mbeans.ServerLifecycleListener debug=0/ Listener className=org.apache.catalina.mbeans.GlobalResourcesLifecycleListener debug=0/ I would be more tempted to look more at the environment variables and possible problems from the long paths though as a proper solution.

Re: Tomcat Class Loader (parent/child tree)
All, Just to let you know that I found out what caused the ClassNotFoundException problem. I found the answer in the release notes of Tomcat 4.0.6. It says the following: Tomcat 4.0 and Sun JDK 1.4 beta 3 Some unpredictable classloading behaviour has been reported when Tomcat is used with Sun JDK 1.4 beta 3. The problem has been fixed with Sun JDK 1.4 Release Candidate or later. I was using Sun JDK 1.4.0_01-b3 together with Tomcat 4.0.3 (which did not give me any problems) and with Tomcat 4.1.24 (which continuously gave me ClassNotFoundExceptions when retrieving BLOBs from the MySQL database).

ClassNotFoundException
Hi! I am stuck with the following challenge. After some initial problems with my web application with regard to ClassNotFoundExceptions when trying to read blobs from a MySQL database which was caused by my lack of knowledge regarding the Tomcat class loading filosophy (which is explained very well in http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html) I am stuck with the following: I started out with a web application that was fully selfcontained i.e. it did not use database or JNDI resources defined in the Tomcat container. So there was a mysql-connector-java.jar in the WEB-INF/lib of the web application and the classes were in WEB-INF/classes. While developing under Forte4J (SunONE Studio update 1, Tomcat v4.0.1, NetBeans, Windows2000) everything seemed to work fine. Then I deployed to a RedHat Linux 8.0 host running Tomcat v4.0.3 and I got the ClassNotFoundException. QUESTION: Can somebody explain - in terms of class loading - why I get the ClassNotFoundException when both the MySQL driver stuff and the web application are in the same class loader context (at least they are there from my point of view). Then I changed to running Tomcat v4.1.24 both on W2000 and RH 8.0 (with JDK 1.4.0_01), I redesigned my web application to use the Tomcat filosophy regarding JNDI and database resources and I still got the ClassNotFoundException, that is until I found the documentation about class loading... What I don't like much is that I have to move part of my web application code (the classes that are stored as blob in the database) into the container's common/lib directory. This causes deployment of my web application to be more difficult and makes my web application less portable. Of course I did NOT read all of the Tomcat documentation, so I will not say that I know all about the different ways to configure a web application in Tomcat, but sometimes a few words in the right direction helps me to focus. I'm off reading more of the Tomcat docs and hope for somebody out there to enlighten me ;-) Regards, Guus

ClassNotFoundException
Hi! I checked the mailing archive and found some mail but never any answers. Here goes I use the following software: + Tomcat 4.1.24 or Tomcat 4.0.6 + mysql-connector-java-3.0.8-stable-bin.jar (in the $CATALINE_HOME/common/lib) + MySQL database server 3.23.51 + my own web application below $CATALINE_HOME/webapps The web application I created writes a blob to the MySQL database (there is no problem here). When the web application tries to read the blob from the database a ClassNotFoundException is thrown in the com.mysql.jdbc.ResultSet.getObject method while wading the object input stream. I tried different versions of the mysql driver software (org.gjt.mm.mysql package) I tried different versions of Tomcat I tried what Sriram Narayanan writes in his message of 21 feb 2002 (put the mysql jar not only in the $CATALINE/common/lib directory but also in the $CATALINA_HOME/webapps/webapp name/WEB-INF/classes/lib directory) . I tried using the Tomcat DataSource resources . All to no avail! Is there anybody who has any ideas ...? Regards, Guus
