Mini HTTP Web server console output

1. WebSphere Studio Application Developer related
   • java.lang.NoClassDefFoundError: javax/sql/DataSource

     WSAD v4.0.3+ contains the fix for this error. You can use the dbbeans.jar in <DB2Everyplace>\SDK\JSP\sample\jsp\VNSchedule_wsad40, which is the jar from WSAD v4.0.3.

   • "Cannot determine search value for column type name <name>. Assumed searchable = true."

     This message is generated by dbbeans.jar and can be ignored.

Web browser

• "The page you are looking for cannot be found."

  If Pocket Internet Explorer displays this message when you try to connect to URL "http://localhost/", your Windows CE device is probably older than Pocket PC v3.0.11171 and you need to obtain a fix for the Web browser. (On the Internet, search for how to connect to localhost through Pocket Internet Explorer.) Make sure the mini HTTP Web server is running.

Application development

• Changes to JSP page are not reflected in the Web browser

  If this occurs, you may need to delete the files in your Web browser's Temporary Internet Files folder or cache.
