Send object to mysql database

hi,
i wondered how i would go about sending changes i've made in
datagrid thats stored in an array back to mysql and only
have the things that were changed in the datagrid updated.
on(release){
var myDataArray:Array = root.dgNieuws.dataProvider
this is where i put the data from the datagrid in the array
ready to send to php
but i don't know quite what to do with it then.
any help would be great
thx

NotSerializableException
This should be pretty obivous, though. You serialize something that's not serializable. Why didn't you just read the API? And thanks to you not printing the stack traces and always catching "Exception", there's no easy way to see where it happens.

Sending colour from a JSP page into a MySQL database field

Dear All,
I am working on trying to send different colours into a MySQL database field from a JSP page.
This is so that I can represent different pieces of data on my webpage tables in different colours providing status depending on the user request.
What is the best way to write JSP code for this?
thanks,

Send form data via email after posting to MySQL database

I have created a form in DreamweaverMX 2004 and then tied it to mySQL database so that on submit the data posts to the database.
This works fine. It also goes to a "success" page just fine. I then added in some php code to also email a few of the fields from the form to a specific email address. This functions correctly using this code below (the email does go - the "from" email address has my login for MySQL database) EXCEPT that the data from the fields does not come through. The field labels are there as indicated below and the email is formatted correctly, but the data doesn't come through.
mail( $to = "[email protected]", $subject = "Someone has submitted an application",
$content= "Essay 1: ".$Essay1."\r\n"
."Essay 2: ".$Essay2."\r\n"
."Essay 3: ".$Essay3."\r\n"
."Essay 4: ".$Essay4."\r\n"
."Essay 5: ".$Essay5."\r\n");
What am I doing wrong?
That's problem #1 - then problem #2 is that I actually also need to send the ID code in this email for the specific record which has been created in my database so the end recipient can associate the email with that specific ID later for other purposes. So even if I figure out problem #1, I'm not sure that I can use this code for problem #2 because the field isn't on the html form, but actually created by the database upon submission.
Any suggestions would be helpful!
Thanks

Serialization big object(100k--2M) into MYSQL database

Hi all !
I have a big object need to be persisted into MYSQL database in my application.
I use two method to meet this request
1 ---- the object implement interface Serializable, but there is serializationVersionID is not same Exception
sometimes.
2 ---- Use XMLEncoder to save my object, the XMLEncoder generate the object XML text about 200k -- 3 M
, but another problem occur :
when I call flush method of XMLEncoder, my application will full ocuppy CPU time, and memory usage will increase to 90M, sometimes will ocurr "Not enough memory" Error.
Why?
can some one help me?
Thanks in advanced

1. You are modifying the signature of one or more of your classes that alters the (system generated) serializationVersionUID and then recompiling. You can declare this for yourself to get control to some extent. See the serialization spec for details.
2. Your object graph is very large, which might be a problem using native or xml formats. Again, the specification details ways in which you can control the serialized form of your objects.
On the information you've provided there's not much more that can be said.

Editing MySQL Database from JTable

Hello everyone, I would like to ask your help on how we can edit JTable cells that would be reflected into the database, or how do we change the database via a JTable.
I have the installer of an application which I made with Java SE called FuelStation.exe
My class files are ready for sharing along with its source files.
I have placed it in this location in my website:

Why is my listener not working or why is it not implemented when I click the cells in the JTable and why is it not reflected into the JTable or into the console?
If this is Flash, Things can be done easily, but this is Java, and I dont know much about this language. I admit that I am new to this -intirely new.

This is a follow up on the code I have posted above.
   public void tableChanged(TableModelEvent e) { // step 4
        int row = e.getFirstRow();
        int column = e.getColumn();
        TableModel model = (TableModel)e.getSource();
        String columnName = model.getColumnName(column);
        Object tableModel = model.getValueAt(row, column);
        // Do something with the data...
        System.out.println(tableModel);
        System.out.println("data");
    }the tableChanged doesnt get called when I would click the cells. The cells are all editable, but as soon as you edit it and press enter, it snaps back to the old data.
How do we make them editable and how do we notify java that the a cell has changed so that we can send it to the database on that specific column of that specific row?
Thanks in advance

Sir,
The exception is probably in here.
for ( int i = 1; i <= numberOfColumns; i++ ){
results[i] = resultSet.getObject(i);
System.out.print(resultSet.getString(i) + " | " );
}ResultSet counting begins with 1 but array indexing begins with 0 your code should look more like.
for ( int i = 0; i <= numberOfColumns; i++ ){
results[i] = resultSet.getObject(i+1);
System.out.print(resultSet.getString(i+1) + " | " );
}Sincerely,
Slappy

i don't know error mean
can anyone explain me and send me a sample code for connect MySQL
Thank you

The java code in your jsp is not valid java code; the error messages are explaining why.
For example, this statement is totally managled.
String sql="INSERT INTO test VALUES (",' " +name" ', ' " +surname+" ')";It should be:
String sql="INSERT INTO test VALUES (' " +name+" ', ' " +surname+" ')";If you use PreparedStatement instead of Statement, then the SQL gets much much easier to write (and PreparedStatement has other advatages as well).
Your other compilation problem is impossible to diagnose without the JSP source code; furthermore, it has nothing to do with JDBC, you simply have broken Java code. You need to post that question in a more appropriate forum.

Saving image in MySQL database

Best groupmember,
I want to save my images in a MySQL database. After storing that in the database I want to be able to present it using a servlet. Something like this (show image with id=4 from the database):
<img src="/servlet/image?id=4">
Would be happy to be guided to example code or tutorials about how to store images in a MySQL database using Java.
-- Best of Times
Peter Lauri

Ok for storing images you'll have to use the type BLOB (=Binary Large Object) for the rest i would suggest that you take a look at the jdbc-documentation....
this might help... :p

BOE XI 3.1 Mysql database connection jar

Hi All,
I am new learner for BOE.I installed Business Object Enterpraise 12.0.
I have created the report WebI rich client and saved in local path, and also some value insert into mysql database table.
I need to know how its stored into mysql database.
which jar file is used for creating the connection with mysql database .
Thanks,
Yousuf
Edited by: yousufalam on Dec 31, 2010 12:40 PM

The connection objects are store in the CI_APPOBJECTS repository table with SI_KIND='Metadata.DataConnection' . The connection properties are stored as property bags along with your objects.
Unfortunately I have just found a reference that this kind of access in not fully supported though and you may have to use the Universe Designer SDK (COM based)
Change password of Universe connection using Java SDK?
Since you are working with the SDK it will make sense to post your questions here:

Accessing mysql database from oracle using dg4odbc

I've been trying to create a database link from a MySQL database to Oracle using the Oracle dg4odbc gateway. I downloaded and installed DataDirect's ODBC package which includes mysql ODBC library (ddmysql24.so) and a generic ODBC libary (libodbc.so). After creating the DSN in odbc.ini, I tested it and it can connect to the mysql database. Then I created the init{SID}.ora file in hs/admin directory, added dg4odbc lines in the listener.ora, and added lines in tnsnames.ora. Then I tnspinged the new SID with success. Finally, I created the database link. However, when I tried to access the database link using the commands "select * from mdl_user@moodle;", I got the ORA-28500 error like the following:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[DataDirect][ODBC 20101 driver][20101]You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right
syntax to use near '"mdl_user"' at line 1
ORA-02063: preceding 2 lines from MOODLE
My mysql database is utf8 by default. Do I have to use latin1?
It seems to me that the dg4odbc translates the sql commands incorrectly (having double quotes around the selected table).
Any help is greatly appreciated.
Jeffrey

The syntax error occures for example when MySQL isn't running in ANSI mode and thus does not allow double quotes around the objects. DG4ODBC 11.1.0.6 by default always adds double quotes to table/column/view names.
A quick test to check if you hit the double quote issue would be to set the MySQL DB into ANSI mode:
- Open SQL*Plus
- execute:
DECLARE
ret integer;
c integer;
BEGIN
c := DBMS_HS_PASSTHROUGH.OPEN_CURSOR@moodle;
DBMS_HS_PASSTHROUGH.PARSE@moodle(c, 'SET SESSION SQL_MODE=''ANSI_QUOTES'';');
ret := DBMS_HS_PASSTHROUGH.EXECUTE_NON_QUERY@moodle(c);
dbms_output.put_line(ret ||' passthrough output');
DBMS_HS_PASSTHROUGH.CLOSE_CURSOR@moodle(c);
END;
- Now run your select statement
=> if it now works, you can permanently change the MySQL config to be ANSI compliant or you can apply the 11.1.0.7 patchset to DG4ODBC.

Submitting Pdf form fields to a MySQL database via PhP

Hi there,
I have recently created a Pdf in Adobe LiveCycle which looks great, and I have added a submit button which is set up to send all the form data in HTML to a PhP file on the server side. The PhP file then collects the form data and inserts it into my MySQL database.
When I run this form from Adobe reader or Professional it works great and the new record is inserted in the database. However I am trying to embed the form into a HTML page, which again looks fine, and all other buttons i.e. Save As, Print work fine.
The submit button however is not working properly now. It inserts a new record into my database, but the fields are blank as if the form data has not been sent or received?
Can you possibly advise me where i'm going wrong.
Much appreciated
Cane

Hi Cane,
I'm relatively new to creating Adobe Forms but I'm looking to do exactly what you have set up, submitting the results to php which sends the results to a database. I don't like the responses being sent to a pdf response file then every so often you have to export to csv then import the results into a database....too tedious. Can you perhaps provide the code that goes behind the submit button and maybe the code that you use on the php/server side? Again, relatively new to this and don't know where to begin but if I can look at the code behind this it would make things a lot easier.
Thanks,
Ed

Need help connecting a remote MySql database from Iphone

Hi, i need to connect to a remote MySql DataBase in windows from IPhone but..... i'm a noob with Xcode and Objective-C.
Can someone help me or explain me the way to do it plz?

I do not think MCPKit will help you on the iPhone. It is just an Objective-C wrapper around the standard mysql libraries which are not available for the iPhone. Your best bet would be to post on the mysql forums and see if you can get any help.
You can try extracting the mysql client library source code into a separate static library project, and see if you can get it to build for the iPhone.

Unable to connect to MySQL database

Hello,
I have written a DatabaseManager class that controls access to a locally stored database, implemented in mysql. In theory, client request should be passed to the DatabaseManager through RMI, but I cannot even create a connection to the database yet!
Here's my connect statement:
con = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/media", "mysql", "mysql");When this statement is executed, the following exception is produced:
java.sql.SQLException: Unable to connect to any hosts due to exception: java.security.AccessControlException: access denied (java.util.PropertyPermission file.encoding read)Can somebody explain to me how I successfully create a connection to the database? I would be extremely grateful. Also, could somebody explain how I could connect to the database from a remote machine using the following connect statement:
con = DriverManager.getConnection("jdbc:mysql://server:3306/media", "mysql", "mysql");I have a feeling I need to grant a certain PropertyPermission in my policy file, but I'm unsure of what values I should be using.
Thank you in advance.
Pete

Thank you for the prompt reply.
In answer to you question: No, it is not an applet. The DatabaseManager is a class that implements a Remote interface, I have it running on the same machine as the mysql database (the server). I then have a small GUI that runs on a client machine which is used to make RMI calls to the DatabaseManager across the network in order to query the database.
When the DatabaseManager object is spawned on the server, it tries to connect to the database to be ready for client queries. This is when it produces the exception mentioned in the original post.
What confuses me is that in my original implementation, the DatabaseManager object was run on the client and the mysql JDBC had no difficulty in connecting to the database across the network. Could the security manager have something to do with it? I am using the RMISecurityManager in conjunction with the java.policy file from the Java RMI tutorial on the Sun website.

Using MySQL database in Jdeveloper

I am using MySQl database in my applicaion.I have successfully created connection to the database and have created entity beans from the tables and a session bean as well to use the entity beans
now when i am trying to call persistEntity(object obj) of session bean, basically to insert records into tables.
i am getting following exception :
Internal Exception: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '"tdmce_approval_status" (APPROVALLEVEL, DOCREFNO, STATUS, COMMEError Code: 1064
Call:INSERT INTO "tdmce_approval_status" (APPROVALLEVEL, DOCREFNO, STATUS, COMMENTS, DMCETYPE, ACTIONDATE) VALUES (?, ?, ?, ?, ?, ?)
bind => [1, 12355, Approved, abcd, import, 12/03/2008]
i believe this insert query is automatically generated by Jdeveloper. have tried executing the same query in sql sheet it has worked perfectly fine.
Can any one please suggest on this ?

Hi Frank,
thanks for your response, there are only setters & getters method in my entity

& session bean class to call the same

public void removeTdmceUserDetails(TdmceUserDetails tdmceUserDetails) {
tdmceUserDetails =
em.find(TdmceUserDetails.class, tdmceUserDetails.getUserid());
em.remove(tdmceUserDetails);
Where else can i look for the query?or for mysql i have to configure some property.
