I am trying to perform batch insertion operation with a list object but while inserting I am getting String cannot be converted to DAO.The receiver in the iterator loop.
I have tried to list the list object, at that time it is printing values from the list. but, when I use generics are normal list it is showing error and I don't find any solution to insert
From this method I am reading the excel file and storing into list
public List collect(Receiver rec)
{
//ReadFromExcel rd = new ReadFromExcel();
List<String> up = new ArrayList<String>();
//List<String> details = rd.reader();
//System.out.println(details);

wb.setMissingCellPolicy(Row.MissingCellPolicy.RETURN_BLANK_AS_NULL);

DataFormatter fmt = new DataFormatter();
String data ="";
for(int sn = 0;sn<wb.getNumberOfSheets()-2;sn++)
{
sheet = wb.getSheetAt(sn);
for(int rn =sheet.getFirstRowNum();rn<=sheet.getLastRowNum();rn++)
{
Row row = sheet.getRow(rn);
if(row == null)
{
System.out.println("no data in row ");
}
else

I want to insert list object using JDBC batch insertion to the database.
Your method collect(Receiver rec) returns the List of strings called up.
return up;
However (if you are really using the method collect to pass the List into insert(List res) method), you are expecting this list to contain Receiver objects. Which is incorrect, since it collect(..) returns the list of Strings.
And that causes an error when you try to cast Receiver rs =(Receiver) it.next();
You need to review and fix your code, so you will pass the list of Receiver objects instead of strings.
And I really recommend you to start using Generics wherever you use List class. In this case compiler will show you all data-type errors immediately.
I am running a thread in eclipse to get data from mysql server. Thread works fine. The problem is after bit of time thread stop running(withing 6 to 8 hours). Thread get freeze. After that I have to manually close and re-run the program. Eclipse runs in a windows server 2012 r2 machine. No error or exception is shown.

a possible reason to this situation is, you are hitting mysql's max open connections error, because you are not closing connections in method CallItem_ListCreate. it seems mysql default max connection count is 151. you are openning 15 connections per hour and after 10 hour you will hit that mentiooned error.
p.s. : you should try running your code in debug mode (or using tools like visualvm, jstack) and view thread dumps as #saurav commented.
I finished making an encryption program that encrypts text and tried to apply this program to encrypt a field in a database table. I have a problem that all the data field is encrypted by on value (last record)
public static void main(String[] args) throws IOException {
String v_url = "jdbc:oracle:thin:#192.168.2.154:1522:orcl2";

con = DriverManager.getConnection(v_url, v_username, v_password);
System.out
.println("Connection to Oracle database was Established");
String sql = "select JOB_NAME from job ";
Statement stmt = con.createStatement();
ResultSet srs = stmt.executeQuery(sql);
while (srs.next()) {
vname = srs.getString("job_name");
}
} catch (SQLException err) {
System.out.println(err.getMessage());
}
Scanner in = new Scanner(System.in);
System.out.println("Enter Your KeyText ");
String StrKey = in.nextLine();
// Print the Concatenated Data.
String ConcatenatedData = StrKey.concat(vname);
System.out.println("The plaintext Data is : " + ConcatenatedData);
// Convering the Concatenated data to Ascii data.
byte[] asciiText = null;
try {
// translating text String to 7 bit ASCII encoding
asciiText = ConcatenatedData.getBytes("US-ASCII");

} catch (java.io.UnsupportedEncodingException e) {

// System.out.println("Reveresd binary :" + ReversedBinary);
mainencdec decimalToBinary = new mainencdec();
String binary1 = decimalToBinary.convertBinaryStringToString(ReversedBinary);
try {
String sql_statment = "UPDATE job SET job_name =?";

con.commit();
System.out.println("An existing user was updated successfully!");
} catch (SQLException err) {

the problem is that the data in job name field is encrypted by the same value as: JOB_NAME
323130,2'2$1'2&0&2#1
323130,2'2$1'2&0&2#1
323130,2'2$1'2&0&2#1
323130,2'2$1'2&0&2#1
323130,2'2$1'2&0&2#1
I want each value in this field encrypted according to its data
I use a jTable jquery for jsp page, it work very well. It can display the showing count records in bottom right of table well (e.g. Showing 1-10 of 22). When I insert the Filtering into the page, the showing count record is not correctly.
I follow this for Filtering: http://www.jtable.org/Demo/Filtering
How to customize the code for showing count record (I use java-jsp and sql server). Sorry for my English language :))
Here is the code I am using right now in controller.
if (action.equals("list")) {
try {
int startPageIndex = Integer.parseInt(request.getParameter("jtStartIndex"));
int numRecordsPerPage = Integer.parseInt(request.getParameter("jtPageSize"));
String jtSorting = null;
//Fetch Data from Rejected_Product Table
lstSite = dao.**getAllSite**(filter_site, startPageIndex, numRecordsPerPage, jtSorting);
//Get Total Record Count for Pagination
int siteCount = dao.**getSiteCount**();
//Convert Java Object to Json
Gson gson = new Gson();
JsonElement element = gson.toJsonTree(lstSite, new TypeToken<List<Site>>() {
}.getType());
JsonArray jsonArray = element.getAsJsonArray();
String listData = jsonArray.toString();
//Return Json in the format required by jTable plugin
listData = "{\"Result\":\"OK\",\"Records\":"+listData+",\"TotalRecordCount\":"+siteCount+"}";
response.getWriter().print(listData);
System.out.println(listData);
} catch (Exception ex) {
String error = "{\"Result\":\"ERROR\",\"Message\":" + ex.getStackTrace() + "}";
response.getWriter().print(error);
ex.printStackTrace();
}
}
and here method getAllSite:
public List<Site> getAllSite (FilterSite filter_site, int jtStartIndex, int jtPageSize, String jtSorting) {
List<Site> siteList = new ArrayList<Site>();
String query = "";
String siteQ = filter_site.getSite();
String clientQ = filter_site.getClient(); // wait
String locationQ = filter_site.getLocation();
if (locationQ.isEmpty()) {
locationQ = "";
} else {
locationQ = "and location like '%"+locationQ+"' ";
}
String site_idQ = filter_site.getSite_id();
if (site_idQ.isEmpty()) {
site_idQ = "";
} else {
site_idQ = "and site_id = '"+site_idQ+"' ";
}
String divisionQ = filter_site.getDivision();
if (divisionQ.isEmpty()) {
divisionQ = "";
} else {
divisionQ = "and division = '"+divisionQ+"' ";
}
int range = jtStartIndex+jtPageSize;
query = "SELECT * FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY CODE) as row FROM [site]) a "
+ "WHERE (code like '%"+siteQ+"' "+locationQ+site_idQ+divisionQ+") "
+ "and row > "+jtStartIndex+" and row <= "+range;
try {
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery(query);
System.out.println("query : "+query);
while (rs.next()) {
Site sitebean = new Site();
sitebean.setName(rs.getString("name"));
sitebean.setCode(rs.getString("code"));
.....
siteList.add(sitebean);
}
} catch (SQLException e) {
e.printStackTrace();
}
return siteList;
}
and here method getSiteCount :
public int getSiteCount () {
int count = 0;
String query = "SELECT COUNT(*) as count FROM [site] ";
try {
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery(query);
while (rs.next()) {
count = rs.getInt("count");
}
} catch (SQLException e) {
e.printStackTrace();
}
return count;
}
If you mean by "not correctly" that the row count is larger than expected, then the solution would be to include the where clause in the siteCount query.
WHERE (code like '%"+siteQ+"' "+locationQ+site_idQ+divisionQ+")
I currently have a web app that has certain classes able to connect to my database, but one other class cant.For whatever reason, I have started to get this exception for one of my classes. Here is what I have done:
I am working with Java 7 and have ojdbc7 in both my class path and lib folder
I have multiple classes who can connect to the url file, yet my other class cant and throws "java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:#someurl"

As mentioned in my last comment, the JAR was on the webapp's class which meant the error couldn't be caused by a lack of drivers. Apparently when deploying my WAR file, tomcat was referencing an older WAR file or something with code that was not updated with the code I had posted above. After exporting my WAR file and renaming to an arbitrary name followed by deploying it under that name, I was not getting the error anymore. Something else to think about is the my messiness of code in the previous war file; I wasn't closing PreparedStatement, Result, and even the Connection variables correctly. Updating the war with a different name with the code posted above worked.
