RE: Having trouble with a JSP compile

["Frances Stewart" <francess@xxxxxxxxxx>]

With WebSphere Application Sever, you do not need to define the Java
compile command.  My first guess would be that your class for the JDBC
driver is incorrect.
>            Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
should be
>            Class.forName("com.ibm.db2.jdbc.app.DB2Driver");
the lowercase com being key.

Also make sure the value specified for system is a valid entry in the
relational database directory (WRKRDBDIRE).

Also, be sure to check the standard output/error log files for the
application server under which your web application is defined for errors
whenever you get a Compilation failed message.  For the Default Server
application server these files are
/QIBM/UserData/WebASAdv/default/logs/default_server_stdout.log and
/QIBM/UserData/WebASAdv/default/logs/default_server_stderr.log
respectively.

I'm not too familiar with websphere, but do you have your java compile
command defined?  The weblogic app server (which I am familiar with)
requires you to tell it the command line to execute to compile the
generated java source into class files.

> <%@ page import="java.sql.*"%>
> <%! Connection con = null;%>
> <%! String system = "AS/400/LIB"; %>
> <%! String userId = "USERID"; %>
> <%! String password = "PASSWORD"; %>
> <%! String url = "jdbc:db2://" + system; %>
>
> <%! public Connection getConnection() {
>    if(con != null) (return con;)
>       try {
>            Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");

Can I suggest that you try and separate your logic from your presentation?
Create another class that contains all the logic required to retrieve the
data & massage it (along with methods to deliver the data to those that
might inquire).  Then in your JSP, import the necessary hierarchy, and call
the appropriate methods to retrieve the data and display it.
