RE: Reloadable Servlet?
Also, if you're using Tomcat 1.4.27 then there's a bug which stops the reload from working properly. A hotfix is available from the jakarta website.

RE: Reloadable Servlet?
Howdy, Your servlet doesn't need to explicitly be "reloadable" but your context does. Set reloadable=true in your context definition.

Reloadable Servlet?
This is one heck of a crach course. :) OK, I found my way through the public_html problem...but now I have a question. I want my Servlet to be reloadable. But, when I recompile and make a minor change (changing the printed string), I get the dumb that follows below in my logs and a 503 return error. If I go to TomCat Manager and Stop and then Start (not Reload) my Servlet, everything works again until I recompile and change. My question is...does my Servlet need to explicitly support a reload? 2003-08-12 23:23:27 StandardContext[/HelloWorld]: Reloading this Context has started 2003-08-12 23:23:27 WebappLoader[/HelloWorld]: Reloading checks are enabled for this Context 2003-08-12 23:23:27 StandardWrapper[/HelloWorld:org.apache.catalina.INVOKER.HelloWorld]: Marking servlet org.apache.catalina.INVOKER.HelloWorld as unavailable 2003-08-12 23:23:27 StandardContext[/HelloWorld]: Servlet /HelloWorld threw load() exception javax.servlet.ServletException: Wrapper cannot find servlet class HelloWorld or a class it depends on at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:891) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:823) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:3421) at org.apache.catalina.core.StandardContext.reload(StandardContext.java:2568) at org.apache.catalina.loader.WebappLoader$WebappContextNotifier.run(WebappLoader.java:1369) at java.lang.Thread.run(Thread.java:534) - Root Cause - java.lang.ClassNotFoundException: HelloWorld at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1444) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1289) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:885) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:823) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:3421) at org.apache.catalina.core.StandardContext.reload(StandardContext.java:2568) at org.apache.catalina.loader.WebappLoader$WebappContextNotifier.run(WebappLoader.java:1369) at java.lang.Thread.run(Thread.java:534) -- - John Blanco - Code Guru @ Rapture In Venice - http://members.bbnow.net/jblanco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Doh. 4.1.27. :-) The hotfix is available here: http://jakarta.apache.org/site/binindex.cgi Click on the Tomcat 4.1.27 link. It's hotfix 22096 apparently. Not sure what the bug number is, and I haven't worked out how to use the bugzilla search form properly yet. There was a discussion about it on this list a couple of weeks ago.
