hello one and all,

i had redhat 9 with tomcat on it. i recently rebuilt the server to
fedora 2 which comes with tomcat 4.1.27-13 with the jk2 connector to
apache. i am currently using

so i am trying to run a servlet that uses the jaybird (
FirebirdSQL-1.5.0Beta3JDK_1.4.zip) drivers to firebird
(FirebirdSS-1.5.0.4290-0). my very simple code works under JBuilder7
but not under the tomcat. the java servlet code is

public static String dbTest() {
String ss = "";
boolean keepgoing = true;
try {
db.setConnection(new
com.borland.dx.sql.dataset.ConnectionDescriptor("jdbc:firebirdsql:localhost/3050:/home/fd/zBrewster/fleet.gdb",
"sysdba", "masterkey", false, "org.firebirdsql.jdbc.FBDriver"));
} catch (Exception e) {
ss = ss+"error[db.setConnection]: "+e.toString();
keepgoing = false;
}
if (keepgoing) {
ss = ss+"db.setConnection sucessful<br>";
try {
db.openConnection();
} catch (Exception e) {
ss = ss+"error[db.openConnection]: "+e.toString();
keepgoing = false;
}
if (keepgoing) {
ss = ss+"db.openConnection sucessful<br>";
try {
db.closeConnection();
} catch (Exception e) {
ss = ss+"error[db.closeConnection]: "+e.toString();
keepgoing = false;
}
if (keepgoing)
ss = ss+"db.closeConnection sucessful<br>";
}
}
return(ss);
}


where i get an error on the openConnection for if i comment that code
out tomcat works fine. below is a copy of the exception returned by
tomcat when openConnection is not commented out...

type Exception report

message

description The server encountered an internal error () that prevented
it from fulfilling this request.
