Parse date to something mysql understands?
I have a date that is a string: April 19, 2014 and I'm trying to turn it into something Mysql will understand. I tried this and it didn't work.
[datetime]::ParseExact("April 19, 2014", "yyyy/MM/dd", $null)
Hi Joey,
Thanks for sharing the solution.
In addition, To format the datetime, this article for your reference:

I hope this helps.

How to insert data into the mysql table by giving as a text file
Hi,
Any one know's how to insert data into the mysql table by giving as a text file as the input in JSP.Please respond ASAP.
Thanks:)At least you can try StringTokenizer to parse your text files. Or download a text JDBC driver to parse your files, for instance, HXTT Text(www.hxtt.net) or StelsCSV(www.csv-jdbc.com).

How do i parse data from the second jframe back to the first?
Hello.
I have a jFrame were I promt users to keep a list of Names in a jTable. (I keep data for something else, but lets say names.. ) Anyway, afterwords I want to add some extra parameters for each name. So I created a new frame, which is opened when user press an Edit button. The new frame opens and users can add for the specific name some extra data, like age, height, color, sex.. etc. that characterizes this person.
On this second form i have a save button, which when its pressed i would like to keep this information for this name, so as when user press edit again from the first frame on the same Name the data that previously entered will be loaded (lets say that the user can not enter the say name again)
I haven' t figured the code for the save Button, but with the rest I am fine.
Can you give any ideas with structures that I have to use and how the action listener will have to be??
When I set visible the new form i have made a constructor that loads the new form which have a label with the name of the person that is edited., but how do i parse data from the second form back to the first that is already opened??
Thanks very much..I found it.. it was not so hard afterall..
anyway, i quote the new code..

Urgent, Please help !!! Input Date field in Mysql database using JSP
Hi All,
Please help me ! I am trying to store a date field in MySql databaseusing JSP on Tomcat Server.I am gettting the following error.
I am taking the String Input and then trying to convert it into date type
inorder to store it into date field in a database.
I am using the following code :
<%
try{
String dt=request.getParameter("avldt");
SimpleDateFormat adt= new SimpleDateFormat("dd-MM-yyyy");
Date sqlToday = new java.sql.Date(adt.parse(dt).getTime());
catch(ParseException e){
e.printStackTrace();
%>
But I am getting the following error message :
Class jsp.myjsp.SimpleDateFormat not found.
Please help me !!!.It's very urgent.
Thanks,
Savdeepprogramming is more then copy pasting, it actually is usefull to think about what you are doing. First you declare that you date is format dd-MM-yyyy, then you want to parse a date in format dd/MM/yyyy and behold Java warns you it cannot parse the one into the second ! Cant you solve the rest of this puzzle yourself then ?

Parsing date/time with extra characters
I have a date/time that I would like to parse to make more readable. The original format is like so:
2009-04-26T19:39:00-04:00
This is the date, then 24hr time which is separated by a T, then the time zone. In this case, the time zone is EDT, -4 hours. I have found that I can parse this with something like formatter = new SimpleDateFormat ("yyy-MM-ddTHH:mm:ssZ");This doesn't work, because of the T in the middle I assume. I have also tried
formatter = new SimpleDateFormat ("yyy-MM-dd" + "T" + "HH:mm:ssZ");This doesn't work either. I get a compile error "Illegal patter character 'T'" for both of these. I am about to split the string into two sections, one with date before T, and one with time after T. Before I do this, I was just wondering if there is a cleaner way to do this, using some wildcard possibly?Try this:
formatter = new SimpleDateFormat(""yyyy-MM-dd'T'HH:mm:ss.SSSZ");{code}
Taken straight from the java docs. Hopefully it'll work.
Edit:
Oops, someone already replied...had the window open too long i guess.

Implementing Database codes FAIL /error in parsing data into jsp page
Hi there,
I have this problem trying to build a portal application. I am using the JSPDynPage, jsp page and a bean to build a page.
I have this problem parsing data from JSPDynPage to the beans and to the jsp page.
I tested out the connection between the beans and the jsp page. There is no error parsing information from the beans to the jsp page.
So i tried to test out the codes for the database from the beans.
Will this work? Because it does not display the results i want.
I need an Solution asap to find out wad is wrong also also the correct codes to the database.
public String db(){
try {
InitialContext iC = new InitialContext();
DataSource dataSource = (DataSource)iC.lookup("java:env/jdbc/mySQL");
java.sql.Connection connection = dataSource.getConnection();
PreparedStatement st = connection.prepareStatement("SELECT name FROM test WHERE id='123'");
ResultSet resultSet = st.executeQuery();
while (resultSet.next()){
name = resultSet.getString("name");
name = name.toString();
connection.close();
return name;
} catch(Exception n){
e = "Exception";
return e;
This is the method i put in the beans to test out the database connection.
Thanks Loads

hi i'm comunnicating with a UDC (Universal digital controller from honeywell) 3000 using VB 6 and the CWSERIAL, but i have a couple of problems the first is that when i send him some data for example when i ask for the temperatura he send me back the next response:
0080C1,120,150 the first 6 digit tell about the communication if it was right or wrong the next 3 digits is the thing that i want to read for example the temperature or the Set point , and the last 3 digits is the value of the thing that im reading in this case the Temperature, what i need yo do is take this and the last value wil be put in a isevensegment the firts 6 digit i have to compare to look for some mistakes, so how can i parse this in 3 parts? i look some example in this page but it gives me type dismatch error i try something like this
response= cwserial1.tasks("Dato").parse(data)
text1.text= response(0)
text2.text=response (1)
text3.text=response (2)
2)And the other question is that i want to know how can i send a data to cwserial and put the option that someone could fill a part of the data , let me explain it better with this example:
when i want to change the Set point of the temperatura i need to send this :
03,0204,65,18,153,200.0,\13\10 and i do that and that's fine the problem is that this program will be used for other people and i want that they only put the value of the temperature and that's all ( the value of the new temperature is the one in red the 200.0). How can i put some text box or something like that, that when someone put some value like 100.0 and the program then send the array of bytes that i put and put the 100.0 where is the 200.0 ?
Appreciating all the help you could give me Tomás Estradahi , sorry for that, i already solved the problem of communicating with the udc 3000 and the first problem that i put in this post about parse the data with vb 6, the only problem that i can't fix is how send a data like i say before i need to send this data
02,0204,65,18,125,100.0,\13\10
the part in red the 100.0 is the value that i need to put to change the Set point of the controllers, and i want to know how can i send this data but adding the value of the new set point from a text box for example that i can put the value in some text box like 200 and that value save it and put in the data 02,0204,65,18,125,value,\13\10 and the send the data to the controller.

Parsing data from indexed field
Hi,
A contractor is developing a program to parse data from a form that I created in LiveCycle. There are some tables in the form where text fields in the same column have the same base name and are assigned an index by LiveCycle. For instance, there might be a CompanyName column with 6 text fields in each of 6 rows, where the text fields are named as follows: CompanyName [0], CompanyName [1], CompanyName [2], CompanyName [3], CompanyName [4], CompanyName [5].
The programmer of the parsing program is having trouble parsing the data for those indexed fields from the XML. Any pointers you could give me (that I would pass on to the programmer) for how to parse data from fields with indexed names like these? I know just a little about what he is trying to do. He said he is using a third-party DLL called iTextSharp for the parsing. If any pointers come to mind on what he might do, please let me know.
Thanks,
EmilyWhen design Adobe forms, you can have multiple fields with same name; as you mentioned your fields can be named as
CompanyName [0], CompanyName [1], CompanyName [2], CompanyName [3], CompanyName [4], CompanyName [5]
However when the form is submitted the form data (in the form of XML) would look like as follows:
<xdp:xdp xmlns:xdp="http://ns.adobe.com/xdp/">
<xfa:datasets xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
<xfa:data>
<form1>
<page1>
<yourSubform>
<CompanyName>My Company 1</CompanyName>
<CompanyName>My Company 2</CompanyName>
<CompanyName>My Company 3</CompanyName>
<CompanyName>My Company 4</CompanyName>
<CompanyName>My Company 5</CompanyName>
<CompanyName>My Company 6</CompanyName>
</yourSubform>
</page1>
</form1>
</xfa:data>
</xfa:datasets>
</xdp:xdp>
Note that all the CompanyName fields are named without any indexing.
If you explain this format to your programmer, he will be able to understand and write a logic to retrieve all CompanyName field's values. -
How to update transaction data automatically into MySQL database using PI

How do I create individual xml files from the parsed data output of a xml file?
I have written a program (DOM Parser) that parses data from a XMl File. I would like to create an individual file with the corresponding name for each set of data parsed from the xml document. If the parsed output is Single, Double, Triple, I would like to create an individual xml file (Single.xml, Double.xml, Triple.xml)with those corresponding names. How do I create the xml files and give each file the name of my parsed data output? Thanks in advance for your help.

Is it possible to insert data into a MySQL database with Java?
Hello everyone!
I would like to know, if it's possible to insert data into a MySQL database, with a JFrame inside a servlet?
When the JFrame is first created it calls this method:
* Connects the servlet with the MySQL database.
private void connect(){
try{
Class.forName("com.mysql.jdbc.Driver");
connection = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/data", "root", "omfg123");
}catch(ClassNotFoundException cnfe){
cnfe.printStackTrace();
}catch(SQLException sqle){
sqle.printStackTrace();
}Then, when you click the "Add" button, it executes this code:
add.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent ae){
String employee = employeeName.getText();
String[] args = employee.split(" ");
firstName = args[0];
lastName = args[1];
execute();
});And this is my "execute()" method:
* Connects the servlet with the MySQL database.
* - And executes the SQL queries.
private void execute(){
try{
PreparedStatement statement = connection.prepareStatement("insert" +
" into employees values(" + firstName + ", " + lastName
+ ")");
ResultSet result = statement.executeQuery();
String fullName = firstName + " " + lastName;
printer.write("Employee " + fullName + " added.</br>");
}catch(SQLException sqle){
sqle.printStackTrace();
}But when I click the "Add" button, nothing happens.This is what I use to insert into mysql. It works on windows.
try {
Class.forName("com.mysql.jdbc.Driver");
String connectionUrl = "jdbc:mysql://" + loadip + "/custsig?" +
"user=root&password=";
Connection con = DriverManager.getConnection(connectionUrl);
newproc = jTextField1.getText();
newsoft = jTextField2.getText();
newdeb = jTextField3.getText();
newcust = jTextField4.getText();
if (newcust.equals("")) {
errorsig12 = 1;
jLabel1.setForeground(new java.awt.Color(255, 0, 0));
} else if (newsoft.equals("")) {
errorsig12 = 1;
jLabel2.setForeground(new java.awt.Color(0, 0, 0));
} else if (newproc.equals("")) {
errorsig12 = 1;
jLabel3.setForeground(new java.awt.Color(0, 0, 0));
} else if (newdeb.equals("")) {
errorsig12 = 1;
jLabel4.setForeground(new java.awt.Color(0, 0, 0));
if (errorsig12 == 0) {
PreparedStatement ps = con.prepareStatement("insert into customer set cust_name = ?, software = ?, processor = ?, debit = ?");
ps.setString(4, newdeb);
ps.setString(3, newproc);
ps.setString(2, newsoft);
ps.setString(1, newcust);
int rs = ps.executeUpdate();
} catch (SQLException eg) {
System.out.println("SQL Exception: " + eg.toString());
} catch (ClassNotFoundException cE) {
System.out.println("Class Not Found Exception: " + cE.toString());

Help parse date : MMM dd, yyyy hh:mm:ss a zzz
I don't know how to get this to work. It parses but give me a wrong date all the time:
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateParserTest {
public DateParserTest() {
public static void main(String [] argv) {
//Nov 17, 2006 1:00:00 PM MST<
String sdate = "Nov 17, 2006 1:00:00 PM MST";
Date date = extractDate(sdate);
System.out.println("Orig date: " + sdate);
System.out.println("Current date: " + date.toString());
public static Date extractDate(String data) {
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd, yyyy hh:MM:ss a zzz"); //zzz
try {
Date date = sdf.parse(data);
return date;
} catch (ParseException ex) {
ex.printStackTrace();
return null;
}Instead of:
"MMM dd, yyyy hh:MM:ss a zzz"you should have:
"MMM dd, yyyy hh:mm:ss a zzz"Minutes are lowercase m's -
Parsing date from JSON response
Is there any helper method to parse date time value being returned in JSONResponse to get java.util.Date. For example, 2012-06-26T15:51:59.078-05:00. I have done simple java method using SimpleDateFormat, but that does not handle all possible formats. Anyone has ideas on libraries that can be used for this purpose?
ChandreshOh I see you receive different formats from different services, who's backend you can not modify.
I found this, it should help you get the job done:
http://stackoverflow.com/questions/4024544/how-to-parse-dates-in-multiple-formats-using-simpledateformat
Note however, that his problem is only relatively simplistic, yours on the other hand seems to be one of a kind where you have to be set up a pretty nifty algorithm taking care of all the different possible formats. That being said, there is no method which can parse ANY format you throw at it. you must write one yourself which knows which possible formats to expect.
If its only those two formats you can expect:
2012-06-26T15:51:59.078-05:00
2012-06-26T15:51:59-05:00
it should be an easy try-catch construct within a helper method. just be sure to use the right letters when setting up your SimpleDateFormat parse object, it's case sensitive and one quickly gets lost in all those letters.
Edit:
Again this should do the trick:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSz");
Just make sure you remove the last ":" from the JSONString (simple string manipulation) and then have two cases
//removing last ":" from JSONString
//====
//Parsing string to date or gregCalendar
GregorianCalendar time= new GregorianCalendar();
try{
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSz");
time.setTime(sdf.parse(JSONString));
catch{
SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssz");
time.setTime(sdf2.parse(JSONString));

Parsing Date with SimpleDateFormat
Hi,
In my application, i want to parse date which is in String format.
The format of Date in String is "yyyyMMdd'T'HHmmss.SSS'Z'" (ex:- 20031201T100116.000Z).
//Happy Case - Input Param "20031201T100116.000Z"
//Output : 2003-12-01 10:01:16.0 is the expected output ------- works well.
//Exception case Input param Value "00000000T000000.000Z"
But the above case breaks as the expected output is "0000-00-00 00:00:00 ". But the output what i get is
"0002-11-30 00:00:00.0"
Greatly appreciate your inputs...,
Here is my code for the above stated case....
private static void printDateFormat(String str) throws Exception
String format = "yyyyMMdd'T'HHmmss.SSS'Z'"; //Desired Format
ParsePosition pos = new ParsePosition(0);
SimpleDateFormat sdf = new SimpleDateFormat(format);
Date date = sdf.parse(str, pos);
Calendar cal = Calendar.getInstance();
cal.setTime(date);
System.out.println("[After Formatting]" + date.toString());
java.sql.Timestamp ts = new java.sql.Timestamp(cal.getTime().getTime());
System.out.println(ts.toString());
Thanks !

IIMS-NZ.SimpleDateFormat is set to lenient date parsing by default, so it's trying it's best to come up with an actual date for 0000-00-00 (what would you say a 'zero' month should be?). You can prevent this "approximation" by using "setLenient(false)", but then you will get a null Date reference for non-parseable dates like the one you're using.
The bottom line is that you're going to have to do some validation for the user input and handle exceptional conditions.
Hope this helps! :o) -
Best data type in mySQL for an Image
What would be the preferred data type in mySQL to store an image
(jpeg or png)?
I would think BLOB would serve this purpose best.
Who is currently doing this and what data type are you using?
Regards,
ScottHi GIlly,
well, we all agreed that the best field type in which to store the image
would me a blob. I still have not succeeded in storing an actual image
in MySQL database (see my post of July 4th).
UbuntuPenguin has been giving me some ideas but I can't get
an image written to the DB. The trick is to encode the image into
a byteArray and I have code for that and for the decode of the
image when reading from the database.
If you take the encoded byteArray and copy it by hand into a blob
field in MySQL every thing is fine. I just can't get an HTTP service
call to do it.
Regards,
Scott
