Thanks Bob. I threw it in and then also tried trowing it in a couple other
places. The only new information was from putting it above line 305(a new
exception is thrown on line 305 so below won't do much :^). This is what
I've got now:
java.lang.NullPointerException
at
com.internetcds.jdbc.tds.Constructors.newConnection(Constructors.java:296)
at com.internetcds.jdbc.tds.Driver.connect(Driver.java:257)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at BasicServlet.doGet(BasicServlet.java:49)
And here is what line 296 is:
public static java.sql.Connection newConnection
// ... snip ...
return (java.sql.Connection)connectionCtor.newInstance(params);
// line 296 ^^^^^^^^^^^^
