If you stare at the black + in the center, the moving dot turns to green. Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating... if you're lucky! It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear. This should be proof enough, we don't always see what we think we see. -- Pradyut http://pradyut.tk http://oop-edge.blogspot.com/ http://pradyutb.blogspot.com/ http://praddy-photos.blogspot.com/ http://oop-edge.spaces.live.com/ http://www.flickr.com/photos/praddy http://groups.google.com/group/oop_programming India March 20 forms authentication and session variablesForms authentication and session variables in asp.net navigate between default and webform3 for sessions navigate to webform2 for forms authentication Sources at: - http://myjavaserver.com/%7Epradyut/files/WebApplication2.zip -- Pradyut http://pradyut.tk http://oop-edge.blogspot.com/ http://pradyutb.blogspot.com/ http://praddy-photos.blogspot.com/ http://oop-edge.spaces.live.com/ http://www.flickr.com/photos/praddy http://groups.google.com/group/oop_programming India March 16 changing to absolute positioning in visual web 2008changing to absolute positioning visual web in visual studio 2008

Then we open the admin console. The snapshot: -  In resources->JDBC->Connection Pool
The main thing here: - The name should not contain underscore or other special characters or it may not work DataSource className: - com.microsoft.sqlserver.jdbc.SQLServerXADataSource Resource Type: - javax.sql.XADataSource In the Additional Properties the parameters should be correrct: -  check out the sql server 2005 port number from Sql server Configuration Manager->Sql Server 2005 network configuration->Protocols for SqlExpress. If the TCP/IP is disabled, enable it. Right click on TCP/IP -> properties In the IP addresses tab, in IPAll see the parameter for TCP Dynamic Ports. same should be in the portNumber in Glassfish server Save the settings and test the connection by Ping button on the page. create a JDBC resource using the JDBC connection pool: -
