Hi,
 
We just install a Apache Tomcat 1.3 on a linux server with JDK 1.2.
 
The JSP files are loaded OK, even we are using Javabeans and there is no problem, but when we are trying to make a conecction from a javabean to a firebird db and this error is thrown:

we put some jar files we downloaded from www.firebirdsql.org on the WEB-INF/lib directory.
 
we have a Apache Tomcat on Windows 98 as well, and is working. OK
 
You can see it on line on:
 
www.lagranjita.com:8080/pruebas 
 
Prueba 1.jsp is just pure JSP
Prueba 2.jspo is JSP with a javabean
PruebaDB.jsp is trying to connect to javabean taht makes aconnection to a firebird db.
 
We don't really know what is the problem.
 
Thanks in advance,
