RE: Classpath Conundrum (2nd try)
For the sake of argument, I moved all the classes from /native into /WEB-INF/classes and I moved all the classes from /foreign into /WEB-INF/lib. Also, for the sake of being extra careful, I packaged up everthing in /WEB-INF/lib into classes.jar (so there's two copies there, the raw directory tree and the JAR file). Then I restarted Tomcat and loaded the servlet. The servlet itself (from the /classes tree) attempted to load, but it broke because one of its dependencies (from the /lib tree) was missing. According to the Application Developer's Guide to which you referred me... When you install an application into Tomcat (or any other 2.2/2.3-compatible server), the classes in the WEB-INF/classes/ directory, as well as all classes in JAR files found in the WEB-INF/lib/ directory, are made visible to other classes within your particular web application. ... no adjustment to the system class path (or installation of global library files in your server) will be necessary. So I expected the contents of /WEB-INF/lib, either the raw files or the packaged JAR, to be automatically loaded. Was I mistaken?

Classpath Conundrum (2nd try)
[I apologize is this message is a dupe. I had trouble sending messages to this group from a hotmail account.] I have been tasked with trying to get a legacy Java Servlet based application running under Tomcat 4.1.24 -- The application currently runs on JRun 2.3.3 On of the requirements imposed upon me is that I can't disturb the existing directory structure. I can't rename or move any directories (or their contents). Our third-party Java classes are in: c:\myapp\foreign Our application and development Java classes are in: c:\myapp\native The root directory of the web server is: c:\myapp\native\web I created the following Context in server.xml: Context path=/tomcat docBase=c:/myapp/native/web debug=0/ Then I created the servlet deployment file: c:\myapp\native\web\WEB-INF\web.xml The contents of said file: ?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-namemyapp/servlet-name servlet-classcom.myapp.servlet.BootStrap/servlet-class /servlet servlet-mapping servlet-namemyapp/servlet-name url-pattern/myapp/url-pattern /servlet-mapping /web-app So now I'm all set to go, except that I'm going to (and did) get a class not found error because there is no /classes directory under WEB-INF and as mentioned above I can't copy the classes from /foreign and /native there. I can't create a symbolic link from /classes to /native since that would be recursive, and it wouldn't include /foreign which is also required. The /native and /foreign directories are in the CLASSPATH environment variable, but as documented in Class Loader HOW-TO that variable is ignored by the class loaders. It would seem to me that the easiest and most straight-forward solution is to get the class loaders to honor the CLASSPATH environment variable. I tried to accomplish this by hacking the start-up scripts, but could not get it to work. Could somebody please help me out here? What's the best way to get the class loader to look in /native and /foreign? Or is there a better solution (other than shuffling the directories around, which I can't do).

I tried that (which was the same as my original attempt, but I tried again just for kicks) and it didn't work. Further investigation revealed that the shortcut to start Tomcat doesn't call catalina.bat at all! Instead, it calls this: C:\j2sdk1.4.2\bin\java.exe -jar -Duser.dir=C:\Program Files\Apache Group\Tomcat 4.1 C:\Program Files\Apache Group\Tomcat 4.1\bin\bootstrap.jar start So I tried hacking the shortcut in the following ways: C:\j2sdk1.4.2\bin\java.exe -classpath %CLASSPATH% -jar -Duser.dir=C:\Program Files\Apache Group\Tomcat 4.1 C:\Program Files\Apache Group\Tomcat 4.1\bin\bootstrap.jar start C:\j2sdk1.4.2\bin\java.exe -classpath c:\myapp\native;c:\myapp\foreign -jar -Duser.dir=C:\Program Files\Apache Group\Tomcat 4.1 C:\Program Files\Apache Group\Tomcat 4.1\bin\bootstrap.jar start But neither worked. After restarting the server, I'm still presented with the expected error: javax.servlet.ServletException: Wrapper cannot find servlet class com.myapp.servlet.BootStrap or a class it depends on Somehow there must be a way to get the class loader to look in the /foreign and /native directories :-( - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I must, if possible, get it working with the existing directory structure. I realize this is not an optimal configuration, but I have no say in the matter. Thank you all for your suggestions. I'll keep my fingers crossed that somebody reveals a clever solution to me soon :-) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
