RE: Tomcat4.0.2 MySQL Connection Pools ClassLoader - bug ?
Title: RE: Tomcat4.0.2 MySQL Connection Pools ClassLoader - bug ? Dear all, I am not exactly sure of what I have found a bug or a JNDI context misunderstanding from me. I have search since three days why, when I follow the JNDI howto, I cannot use JNDI datasource due to bind problems. The reason was that I use JBuilder : to compile I must include the required .jar. BUT when he generate the war, jbuilder include all the jar. Catalina find the jar in /WEB-INF/lib and seems to create another Context that can not access to java:comp used by common/lib I have just remove the /WEB-INF/lib directory and everything is running ok. Is it a know issue ? -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

Title: RE: Datasources context ?
In fact I just reading the JNDI Howto and try to set up the thing for the very first time for JDBC access
Someone (Mark) seems to have the same kind of problem with oracle ;(
Where can I find a working test sample ?

I have got this error
Name java:comp is not bound in this Context
When I try the following code :
try {
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/env);
DataSource ds = (DataSource) envCtx.lookup(jdbc/TestDb);
Connection conn = ds.getConnection();
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery(SELECT prenom,nom FROM
annuaire;);
while (rs.next()) {
out.println(p + rs.getString(prenom));
out.println(nbsp; + rs.getString(nom));
}
conn.close();
} catch (Exception e) {
out.print(e.getMessage());
}
Well, the big questions are:
- where is that code fragment located ?
- are you modifying the context classloader ?
To end up with the right JNDI context, Catalina uses context classloader
associations. So if you get the error you're getting, it means that the CL
association is not the one it should be. There were a few bugs caused
because in some places, it wasn't set properly (for example, you can look at
bug 5330).

May be you have defined at a wrong place your resource in your
server.xml file.

RE: Determining User Connection Speed
Title: RE: Determining User Connection Speed Check on IP : lan and dialup should be different ! -Original Message- From: Jim Urban [mailto:[EMAIL PROTECTED]] Sent: Friday, February 15, 2002 6:03 PM To: Tomcat Users List Subject: RE: Determining User Connection Speed Our clients run our application on both the internet and intranet. The users who use the application on the intranet are usually on a 100MB (LAN) network directly attached to the application server. For these users the application really hums. For those on the internet, using 33kb or 58kb dialup connections, the application is very slow downloading data. We have experimented with sending back the data compressed with mixed results. That is, the dialup users see a significant drop in download time while the intranet (100MB LAN) users actually see a slow down in performance do to the additional time needed to compress and uncompress the data. If we could tell when a user is on a dialup (slow) connection we could compress the data and not compressing it for those on a LAN connection. Jim -Original Message- From: Christopher K.
