Обсуждение: Program accessing database via servlet
Hi, all. I am having a problem when accessing the postgresql database via servlet. I set up a java web server (Win 95), and my servlet program need to access the remote postgresql database which is not on my server. When the program executed DriverManager.getConnection(dburl, user, passwd), it shows the error: java.lang.IllegalArgumentException: Argument # > Arg length But the similar program which I don't use servlet runs ok, it can access the remote database very well. I don't know why. And if I change the database to the MS Access database which is on my machine, the servlet program also runs fine. Anyone can help? Thanks.

I had the samme problem on my system (mac > linux). Make sure that you, if you load the dburl, usr and password from a file, removes ANY tailing spaces. If you get the the same error try to hard-code the dburl,usr and password into your program (during debuging).

Try the newest JDBC driver first (from the CVS). It *should* return you the correct error message then which I guess is something like "wrong username/password" or so in your case!

Switching to the new 6.5.2 driver fixed the problem for me. -- Richard Morrell richard@ednet.co.uk Operations Manager - edNET: InternetWorkingSolutions - http://www.ednet.co.uk
