Re: Clear Cache In IE5
The last thing you can do is to stop tomcat, erase everything inside TOMCAT_HOME/work and start it again. Thank you so much!!! It works now. This problem has bugging me for a very long time.

Hi Try to add headers: response.setHeader(Cache-Control, no-cache, must-revalidate, max_age=0); response.setDateHeader(Expires, 0); response.setHeader(Pragma, no-cache); Thanks for the tip. I'll include that in my development code. just at the begin of a script. Should work on almost all browsers.

Update changes
How can I update the change that I've made to my webapp's directory in TomCat 4.0? Here's the situation, I deleted an unwanted directory in my webapp's directory, but it's still being showed after I restarted TomCat and the browser - well, I actually rebooted the machine. I've set reloadable to be true for my webapp in the file server.xml, although it's irrelevant because that's for reloading the classes. In fact, I don't have any class files in either WEB-INF\classes or WEB-INF\lib, because my app is an applet. Therefore, I'm getting the feeling that the reloadable attribute won't help me to reload the change I've made to the applet. So in short, is there a command or setting I can ask TomCat to reload everything regardless what. -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
Re: Location of jdbc driver
Hi ya, Let's share this with the others ;-), and I think this should be mentioned in the docs. Anyway, here how I do it, I place the *driver directory tree* in the directory as the other class files. For example, my servlet application is called, myApplet, and I put all the class files for this app in myClasses, so the directory tree will look like this, myApplet--myApplet.jsp | myClasses | --(class files for the applet) | --org(this is for the MySQL driver) | gjt | mm [...] See the deep directory tree for the driver, but all you need to do is unjar it. If you use WinZip, right click on the driver file and unzip (unjar) it. I hope you will find this useful. - Original Message - From: Satish Talim [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, November 20, 2001 3:30 PM Subject: Location of jdbc driver Hi, I am facing the same problem.

Re: [repost] loading class files
[...] But from one of the Tomcat's docs, which is tomcat-docs\appdev\deployment.html, in its mid page says, /WEB-INF/lib/ - This directory contains JAR files that contain Java class files (and associated resources) required for your application, such as third party class libraries or JDBC drivers.

You have saved me! [...] Thanks for your thanking! :-) I was very frustrated, I was trying to get this working for a week and I didn't get anywhere, that's why the big thanks ;-). BTW, there are two kinds of class/jar in a webapp: - for Servlet/jsp(it works in server-side) - for Applet or other static content(it will be downloaded to client together with Applet class, and works in client-side) I think the reference email means: - class/jar for Servlet/jsp itself should be put under WEB-INF - class/jar for static content should Not be put under WEB-INF I think your JDBC driver is used by your JSP directly, it works in server-side, (it is not downloaded together with your Applat and work in client-side), so now, as you say, your JDBC driver should be put in WEB-INF/lib. I'm just wondering the JDBC driver is working on the client side, cos' if I place the driver jar file in WEB-INF/lib directory then it can't be found. I've also tried the common/lib directory, as the other helpful folk suggested, and it can't be found there, either. I've actually embedded my database connection in the applet, so it does look like I should place the driver on a separate directory.

Re: [repost] loading class files
I use this setup on my linux box (TC 4.0.1, MySQL JDBC, Mandrake 8). The only issue I've ever had with the driver is the downloaded MySQL JDBC driver file needs to be unjarred. The .jar file nested inside is the actual JDBC driver. Place it in WEB-INF/lib and restart Tomcat so it can find the file. Alternatively, this file can be in CATALINA_BASE$/lib or CATALINA_BASE$/common/lib if you want it available to all your apps or all your apps and Tomcat itself respectively. My applet uses the JDBC directly, so I've unjarred the driver and everything works fine now. Thanks for clearing things up for me. Note on the other stuff: Classes used on the server side should be in a package structure under WEB-INF/classes to work correctly. JSPs, static content, and client-side applets should all be outside the WEB-INF folder for proper operation. This is defined in the spec and is required for all applications conforming to it. Hope this clears some mystery. --David Smith On Monday 19 November 2001 12:41 am, you wrote: Sorry guys this is a repost.

I suggest you also read the Application Developer's Guide included with Tomcat. The Tomcat 4 version is also online at: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/appdev/ From the point of view of the server, applet classes and JAR files are just static content.
