Subject RE: More Tomcat problems.
Date Mon, 04 Dec 2000 11:01:21 GMT
 Hello to everybody. I am using a try-catch pair. I have something like
"<username>", "<password>");
  catch (ClassNotFoundException cnfe)
  catch (SQLExepction sqle)
  but Tomcat just crashes when the: Connection
"<username>", "<password>");  line is encountered. I have to say here that
the above code works fine if I use simple class to obtain connection with
the database. Any more suggestions.
  Thank you.

Are you using a try block around the code to catch SQLExceptions
in your development setup?
This is what is happening: you are throwing an exception without
a handler. The jvm just unwinds to the top and drops you out. 
Try using something like this in the JSP:
<%@ page errorPage="error-page.jsp" %>

or else debug the connection code in an IDE first.

Subject: More Tomcat problems.

  Hello there again, this is the second message I am sending regarding
problems with Tomcat. In my previous message Kief answered solved my
question correctly, so I would really appreciate if he could answer again
this one. It seems that I have exactly the same problem. I am running a JSP
file (lets say myFile.jsp) that open a conenction with the database on the
server. The code is like the following:

  <% ..... 
        String url = <the url string>; 
        String user = <the user string>; 
        String password = <the password string>; 

        Connection con = DriverManager.getConnection(url, user, password); 


When the line Connection con = DriverManager.getConnection(url, user,
password); is encountered then Tomcat just goes off (and I get the error
message from Apache "Internal Server Error....."). Just like that, with no
error messages or anything. This is really weird because I have downloaded
and installed the latest versions of both Apache (v1.3.14) and Tomcat (v3.2)
and I have included the JDBC driver .jar file in my classpath.

  I have looked in the "tomcat.log" file and there are no error messages. I
have looked in the "error.log" file in the Apache directory and I get the
error message (for one more time): [Thu Nov 30 17:47:39 2000] [error]
[client] Premature end of script headers:
c:/work/tomcat/jakarta-tomcat-3.2-b7/webapps/panos/myFile.jsp. I cannot
think of anything to do so if somebody knows more about that please help.

   Thank you.
