I wrote the following code to fetch data from my oracle database and show the result using JSP:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%# page import="java.io.*,java.util.*,java.sql.*"%>
<%# page import="javax.servlet.http.*,javax.servlet.*" %>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
<!DOCTYPE html>
<html>
<head>
<title>SELECT Operation</title>
</head>
<body>
<sql:setDataSource var="snapshot" driver="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#localhost:1521:orcl"
user="hr" password="Hrone699"/>
<sql:query dataSource="${snapshot}" var="result">
SELECT No from Client;
</sql:query>
<table border="1" width="100%">
<tr>
<th>No</th>
<th>Client</th>
<th>Information Collection Date</th>
<th>Payment Notice Date</th>
</tr>
<c:forEach var="row" items="${result.row}">
<tr>
<td><c:out value="${row.No}"/></td>
<td><c:out value="${row.Client}"/></td>
<td><c:out value="${row.INFOCOLLECTINGDATE}"/></td>
<td><c:out value="${row.PAYMENTNOTICEISSUEDATE}"/></td>
</tr>
</c:forEach>
</table>
</body>
But I am getting the following error:
An Error Occurred:
SELECT No from Client; : ORA-00911: invalid character
With the following Stack Trace:
javax.servlet.ServletException:

Just remove semicolon(";") from sql statement because oracle driver don't required to end sql statement with semicolon but you have to mention semicolon(";") when you are working with MySQL DataBase(mysql-connector driver)

You need to have getters for jsp el expressions, it won't recognize public properties.
Change your MovieRecommendation class (and possibly others) to something like this:
#QueryResult
public class MovieRecommendation {
Movie movie;
int rating;
Movie getMovie() { .... }
int getRating() {....}
I try to configure spring with tiles and create a website - one to mane relation -> Klient - Pobyt and got a question regarding configuration.
I have got a class Klient and a class Pobyt, I also set up a view, but I am getting a null pointer exception when using = ${klient.idKlienta} in order to connect a klient to a list of pobyt`s.
I am getting a org.postgresql.util.PSQLException:- Error in postgresSQL syntax.
Using a concrete value in sql works fine.
Any idea what is wrong?
Could yoy help?

2014-02-22 18:43:36 CET Query:

where idKlienta =
So the problem is the idKlienta is not passed to the query? How can I solve it?
Used this StackOverflow answer to try an implement a submitless form. The page consists of a selectomenu control and a table. On change of the selection I wish to refresh the table body. The page loads without issues, but when the selection is made I get the following error occurs:

I'm using JBoss-AS-7.1.1, and the selectonmenu looks like this:
<h:selectOneMenu id="ship"
value="#{shipManager.current}">
<f:selectItems value="#{shipManager.list}"
var="ship"
itemValue="#{ship}"
itemLabel="#{ship.name}" />
<f:ajax listener="#{shipManager.changeShip}" />
</h:selectOneMenu>
If I remove the ajax component then no issues although (of course) the shipManager is not updated.
Once I have the selection made I would then like to add the renderer part to refresh my table body.
Many thanks for any help given.
Steve

Your stack trace looks incomplete in that it doesn't actually refer to your code(which is where I'd expect the npe be thrown). That notwithstanding, your select menu doesn't have a converter, so any other problems aside, your form would probably still not save or register the selection
Implement a JSF converter and declare it on that selectonemenu. This is mandatory when a select type component needs to select and save complex POJO types You can look at this example
Try to get rid of that gigantic <h:form/> in your markup. There are too many other components in that form that could be causing you problems. Break the components into smaller chunks in separate forms
If the scope of your bean is #RequestScoped then change it to #ViewScoped , in general ajax better be done with #ViewScoped... cause new instance of the bean created upon each submit...
#ManagedBean(name="shipManager")
#ViewScoped
Also Make sure that the changeShip method takes AjaxBehaviorEvent as the parameter
(ie)
public void changeShip (AjaxBehaviorEvent event){
//** do your stuf
}
and also specidy the execute and Render attributes inside f:Ajax
<f:ajax execute="ship" render="#form" listener="#{shipManager.changeShip}" />
