I have a strange problem. I've set up a new tomcat installation on a new Linux Slackware computer. I am doing the following:

try {
  con = DriverManager.getConnection(jdbc:sqlserver://sqlhost\\instance:1433;loginTimeout=10;user=myuser;password=mypass;");
catch (SQLExceltion e) { .... }

This works just fine in serveral java programs I have written on this machine, but when I use this in jsp I get an exception. e.getErrorCode() is zero; e.getMessage() is ""cantleys: cantleys: Name or service not known"

I am at a loss about this error. I have successfully installed java and tomcat on three other Linux hosts w/o this problem. "cantleys" is the hostname of this Linux computer. Why is it mentioning it as a service name? Why does this only happen with jsp but not regular java?

I am using the same tomcat version and same sqljdbc.jar on all machines. I've put the sqljdbc.jar file in .../webapps/myapp/WEB-INF/lib and in $CATALINA_HOME/lib, and it both places at once, no difference. If I remove the sqljdbc.jar file from these libs I get java.lang.ClassNotFoundException:, so I know it is using the correct jarfile.
This is killing me! I've been messing with it for hours and comparing with the other computers. Help! I've got a deadline!!!
