Re: How to get changed class to reload
It seems that others are having the same problem. Does it work in some cases and not in others? If you can't get a changed class to reload, how do you develop applications? Is there another way of working that bypasses the need to frequently test changes to a class? It seems that the shutdown-startup process would eat up a lot of extra time in the development process. But I'm new to JSP and Java so I may be missing a better way of doing it. How do most Java developers do it? Or does the reload work for most people? -Gary Lundquest - Original Message - From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, May 17, 2001 9:35 PM Subject: Re: How to get changed class to reload > Hi, > Oooops I have the Java sources in the class directory and in addition > some java sources and class files n outher directories on my machine.

Re: How to get changed class to reload
Hi, Oooops I have the Java sources in the class directory and in addition some java sources and class files n outher directories on my machine. And whenever I touch my JSP or ine of the java files in classes directory, everything what needs to be rempiled is recompiled, even the javas in total differnent directories. So I have no idea why that doesn't work with you configuration.

Re: How to get changed class to reload
Yes, I looked at that, and reloadable is set to true. But it does not reload. - Original Message - From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, May 17, 2001 1:07 AM Subject: Re: How to get changed class to reload > HI, > > just have a look at your server.xml in tomcat/conf directory. > > There are context definitions. > > In these context definitions you can set a flag named reloadable to true: > > looks like this: > > > > for the context test. > > Sascha > > >
Re: How to get changed class to reload
Hi, I think you are wrong and my Tomcat Server makes me quite shure about this. You can put a reloadable flag in the context defifnition in the server.xml. (See my posting from 1 minute ago for details) Sascha
Re: How to get changed class to reload
HI, just have a look at your server.xml in tomcat/conf directory. There are context definitions. In these context definitions you can set a flag named reloadable to true: looks like this: for the context test. Sascha
Re: How to get changed class to reload
Hi, Actually u have to restart the Tomcat Server whenever a change is made to the servlet .. there is no other go .. the server does not automatically detect the change in the class file .. Once u start the server ..the class file is actually loaded once ..this the advantage ..coz you need not compile the servelt everytime you load the servlet ..but you have to restart the tomcat server once a change is made From: Gary Lundquest <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: How to get changed class to reload Date: Wed, 16 May 2001 22:54:32 -0500 I am a new tomcat user (ver 3.2.1) on RedHat 7.0. I put a test servlet in the webapps/examples/WEB-INF/classes directory and it ran fine. But when I modifiy the .java file and recompile it with javac, I cannot get the modified version to display in the browser. I'm pretty sure it is not a cache problem in my browser. I even deleted the .class file and the old result still displayed. I can get the changes to appear by shutting down and starting up tomcat. But I cannot figure out how to get the old class out of tomcat's cache (short of shutting it down). I've read most of the included documentation and it talks a lot about being able to reload a changed class, but no matter where I've tried to put the servlet class in the directory structure, or what I add to the XML files, I can't get it to reload. What is the trick to it? How does tomcat detect whether the class file has been modified - does it check the file date each time it is called? Do I need to be using some tool other than a text editor and the javac compiler for the servlet class? Any help will be appreciated.
