Subject Re: SOLVED: Pool: NoValidConnectionException on jdk1.4 -> Berin, please read this
Date Tue, 02 Apr 2002 10:36:28 GMT
Hello again,
one snippet more:
in the same file (ResourceLimitingJdbcConnectionPool.java also in line 156
you must insert the "3" -> Jdbc3Connection conn = (Jdbc3Connection)poolable;
Now you will get your page every time you reload.

Berin: What did you mean with "I will change it in both classes"?
                                                   ^^^^^^^^^^^^

Regards,
Michael
