I'm totally stuck with this pagination in primefaces please could some one help me with good solution
You got a Problem with polluting your server and the database with db-connections. This leads to your error, the DB does not allow any further connections.
To avoid this you must close the connections and free the resources on your server, as well on the DB-server.
I will post a snippet with correct resource-handling. Doing this, I will also use correct Java Code Conventions, especially: Classnames should start with a uppercase letter.
Class.forName("oracle.jdbc.driver.OracleDriver");
List<Customer> cs = new ArrayList<Customer>();
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
try {
con = DriverManager.getConnection("jdbc:oracle:thin:#localhost:1521:XE", "invoice", "google");
stmt = con.createStatement();
rs = stmt.executeQuery("select customerid,customername from customer order by customerid asc");
while (rs.next()) {
Customer cm = new Customer();
cm.setCustomerid(rs.getInt(1));
cm.setCustomername(rs.getString(2));
cs.add(cm);
}
} catch (Exception e) {
LOG.error("Error connecting to DB: " + e.getMessage(), e);
} finally {
try {
// close resources
rs.close();
stmt.close();
con.close();
} catch (Exception e) {// ignore
} finally {
// setting everything to null (allows Objects to be GC'd)
rs = null;
stmt = null;
con = null;
}
}
return cs;
Bare in mind: gathering a connection to DB is expensive. Consider using ConnectionPooling (like c3p0). ConnectionPooling will open a set of connections to the db for you and reuse them.
Your error is here:
at com.invoice.customerlisting.getcustomerlist(customerlisting.java:22)
That is this line:
Connection con=DriverManager.getConnection("jdbc:oracle:thin:#localhost:1521:XE","invoice","google");
You have a problem here on connection and not in primefaces. Isn't trying to open many connections? Try to open the connection just one time in some other method, and on getcustomerlist just create the statement.
public class customerlisting {
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con=DriverManager.getConnection("jdbc:oracle:thin:#localhost:1521:XE","invoice","google");
public List<customer> getcustomerlist()
{
List<customer> cs=new ArrayList<customer>();
try
{
Statement stmt=con.createStatement();

So I'm using Mybatis 3 to make procedure calls. This is the first time I'm using this method to make calls to an oracle database (the other times it was a mysql database) and i get the above mentioned error. I have never had an issue making mysql database calls in the same fashion is there something special i need to do with oracle? It seems that this error message generally means that the number of parameters or '?' don't match the what's being set, but as can be seen from my xml file I am setting all the parameters.

My implementation
private User authorizeAccess(String id){
SqlSession session = sqlSessionFactory.openSession();
Map<String,Object>params = new HashMap<String,Object>();
params.put("id", id);
params.put("cycleType", "TDU");

}catch(Exception e){

The xml file
<mapper namespace="call">
<resultMap id = "userMap" type="com.cmplnr.core.User">
<result property="id" column="ATTRIBUTE1"/>
<result property="fullName" column="USER_NAME"/>
</resultMap>
<select id = "authenticateCmplnr" parameterType="java.util.Map">

#{errmsg, mode=OUT, jdbcType=VARCHAR}

</select>
</mapper>
Can you try putting your OUT parameters to the Map, with null values?
You can see this possibly dupe answer.
private User authorizeAccess(String id){
SqlSession session = sqlSessionFactory.openSession();
Map<String,Object>params = new HashMap<String,Object>();
params.put("id", id);

i've written this code for adding photos to database and i'm not much into web application
so please help me out
// obtains input stream of the upload file
inputStream = filePart.getInputStream();
}
Connection conn = null; // connection to the database
String message = null; // message will be sent back to client
try {
// connects to the database
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/opmdb", "root", "sourabh");
// constructs SQL statement
String sql = "INSERT INTO photos (userId, photo) values (?, ?)";
PreparedStatement statement = conn.prepareStatement(sql);
statement.setString(1, userName);
statement.setBinaryStream(2, inputStream);
here it is telling the error i've also used setBlob but the error remains the same
Exceptions and stacktrace is

change your code statement.setBinaryStream(2, inputStream);
to
statement.setBinaryStream(2, inputStream,file.length);
'setBinaryStream' method need 3 parameteres,add your file length in this method

Here,
} finally {
pstmt.close();
conn.close();
}
you aren't checking if they are null before you close them. If an exception is been thrown upon connecting, they will stay null. Fix it as follows:
} finally {
if (pstmt != null) pstmt.close();
if (conn != null) conn.close();
}
There are no other potential causes for a NPE in the addEmployee() method. I see that you've an e.printStackTrace() call in the catch block. Read this one for the real cause of the problem. I guess that it's a ClassNotFoundException on the JDBC driver class, because you forgot to put the JDBC driver in /WEB-INF/lib folder of the webapp.
