Yes. The syntax for the Resource tag in the server.xml has changed. The
resource parameters are no longer defined in tags nested into the
Resource tag, but in attributes of the tag. This is an example from the
Tomcat 5.5 documentation:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html

DBCP ClassCastException
Hi all,
I'm getting a the following ClassCastException running Tomcat 5.5.9 with
MySQL
java.lang.ClassCastException: org.apache.tomcat.dbcp.dbcp.BasicDataSource
Here's the relevant code:
*Java code:*
org.apache.commons.dbcp.BasicDataSource datasource;
datasource = (BasicDataSource)ctx.lookup("java:comp/env/jdbc/myserver");
*web.xml*
DB Connection
jdbc/myserver
javax.sql.DataSource
Container
*server.xml*
**
factory
org.apache.commons.dbcp.BasicDataSourceFactory
*...*
This same code works in Tomcat 5.0.30.
Has anything changed? Am I missing something?
Thanks.
Re: Simple JavaBeans applications not working (newbie question)
From: "Michael Strorm" <[EMAIL PROTECTED]> skeleton/WEB-INF/lib/subapp/Beany.class Jar files go in WEB-INF/lib. Classes go under WEB-INF/classes in a directory structure matching the package name. What package statement does Beany.java contain? org.apache.jasper.JasperException: /subapp/skeleton.jsp(2,0) The value for the useBean class attribute subclass.Beany is invalid. Shouldn't that be 'subapp.Beany' and not 'subclass.Beany'? That's why I asked, above, about the package statement. Before you continue, you might shut down Tomcat and delete the 'work' directory associated with this webapp to make sure you're starting fresh. (I assume such a thing exists in version 5, I'm still using 4.1.) You're close, just change one thing at a time until you figure it out. -- Wendy Smoak - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Cannot download files with IE through tomcat. SSL with no-cache problems?
As posted by Tim Funk in reply to your original message, the details regarding this problem are found here: http://issues.apache.org/bugzilla/show_bug.cgi?id=27122 Note that it is a problem with IE only, wherein IE can't handle no-cache cache directives, and Tomcat only sets these headers when serving content from a protected context. Also, if you're using other than form authentication, you need to substitute the class name for your authenticator in the configuration described below. Donny R Rota wrote: I found the solution!

Re: trouble with Font objects in Tomcat
Your class comments indicate a different purpose than your class code,
but assuming a connection in your mind, code something like the
following might be helpful to you:
public class Fonts {
public static Font [] getFonts() {
return GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();
}
public static String [] getFontNames() {
Font [] fonts = getFonts();
String [] fontNames = new String [fonts.length];
for (int i = 0; i < fonts.length; i++) {
fontNames[i] = fonts[i].getFontName();
}
return fontNames;
}
public static String [] getFontFamilies() {
Font [] fonts = getFonts();
String [] fontFamilies = new String [fonts.length];
for (int i = 0; i < fonts.length; i++) {
fontFamilies[i] = fonts[i].getFamily();
}
return fontFamilies;
}
public static String [] getNames() {
Font [] fonts = getFonts();
String [] names = new String [fonts.length];
for (int i = 0; i < fonts.length; i++) {
names[i] = fonts[i].getName();
}
return names;
}
public static void main(String [] params) {

Re: trouble with Font objects in Tomcat
I agree 100% with Farhad. The problem is not with headless but with
your code. The exception tells you exactly what is happening. Your
code is not finding the font. If you want to build fonts, you have to
upload the font files with the right TextAttribute settings.

(Bangs head against wall several dozen times) Thank you. That was such a stupid mistake; I should have spotted it. If there is any excuse it is that I'd had what *looked* like the same problem with two earlier attempts; the package name was not the problem there.

Hi, Yes Connection pool is good because it gives a performance boost to your application ( because open connection / close connection is cpu and network intensive ) You dont have a to configure DBCP in tomcat. you can do that in your application as well.

I have read a lot on the web that using a connection pool is very good. I just wondering why I should configure DBCP in tomcat? i think if i write the database connection in jsp pages(not in beans) I need configure DBCP in tomcat. if in the page I just call some JavaBeans to connect to database, i just need write a connection pool class in java. is that true? thanks -- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
