Last message was not explicit, this is my case:

1) Build a java class (Bean) which provide access to database, this
is an example:

------------------------------------------------------------

public class SiteData{

private Connection dbData;
private PreparedStatement qrData;
private ResultSet rsData;

public void openDB(){
Class.forName(JayBirdDriver);
dbData = DriverManager.getConnection(JayBirdURL, "dbUsr", "dbPwd");
dbData.setAutoCommit(false);
}

public void closeDB(){
dbData.close();
}

public void insertData(int pData1, String pData2){
qrData = dbData.prepareStatement("INSERT INTO tbl " +
" VALUES (pData1, pData2)");
qrData.executeUpdate();
dbData.commit();
}

public String[] getData(){
String[] sData;

qrData = dbData.prepareStatement("SELECT dato1 " +
" FROM tbl");
rsData = qrData.executeQuery();
while (rsData.next()){
sData = rsData.getString(1);
} // while
rsData.close()

return sData;
}

}
------------------------------------------------------------

2) JayBird Drivers are installed on Tomcat/lib directory, driver is
installed for all Tomcat applications.

3) Under Tomcat/webapps directory exists an application named
jayBird, which contains 3 jsp pages: welcome.jsp, report.jsp,
endAppl.jsp. Each page uses SiteData as session bean, following tag
is included at each page:

<jsp:useBean id="objData" class="SiteData" scope="session" />

4) welcome.jsp calls objData.openDB(), then post (calls) report.jsp
page.

5) report.jsp calls objdata.insertData(), objData.getdata() methods,
then post (calls) endAppl.jsp.

6) endAppl.jsp calls objData.closeDB() method, then invalidate
sesion: session.invalidate();


Those are my cases, I don't know what changes must execute, if you
need more information, please notify me.

Best Regards.
