J2ee and mysql

hi guys, pls pardon if this has been asked b4...
is it recommended to use j2ee with mysql? are they fully compatiable? if not, what database should be use with j2ee?
thanks!

Is your JdbcRowSetImpl this?
http://developers.sun.com/prodtech/javatools/jscreator/reference/docs/apis/rowset/com/sun/rowset/JdbcRowSetImpl.html
If so, then I notice there is an insertRow() method. Before you call that method, though, you have to call moveToInsertRow() to prepare, then call setInt() or setString() and so on to fill in the data.

  • Few questions about j2ee and my program

    Hello
    I'm new on this forum and in j2ee :)
    I've to write program which should be in working similar to video on demand system but without streaming movies only database and etc.
    I'm gonna write database in mysql. It will contain user and movies. I'll use the tomcat server.
    Can you tell me what should i learn to do it, i mean can i use jdbc to do it or maybe i should use something diffrent, and what will i need more i mean jsp, servlets?
    Sorry for such a question but i'm just beginner in j2ee and i hope you will help me :)

    jsp, servlets?Yes, learn JDBC. And servlets and JSPs. That's quite a lot.
    Sorry for such a question but i'm just beginner in

  • New to J2EE and web development in java

    Hi folks,
    I have been developing desktop app in C# for the past two years. But now I am taking my masters and I am learning in Java. I am also interested in J2EE and wanted to develop web apps in Java. The problem is, I am very much confused with the tools, classes and etc Java uses. For example people say to me, you have to know Struts, Spring, JSP, Ant, Tomcat, Apache Tomcat, Hibernate, and etc. I tried to search every one of those and got some clue but not that much detail and now I am really confused.
    Before I go to coding (which is my interest), I wanted to know what tools to know and why and how they are used, at least the basics. Once I get some idea, I will keep on searching by myself. Can any body please tell me or give me a link of what tools I have to start with as a begineer web developer? Can any body give me a brief description about them?I downloaded Eclipse and I am almost familier on how to use it and I also write some code on it. These days, I downloaded J2EE, Struts, and Hibernate but I dont know how to use them and where to use them. No clue. Help me guys.
    Thank you.

    Step 1 : Download "Eclipse IDE for Java EE Developers". You don't need anything else in terms of tools at the start.
    Step 2 : Get solid experience in basic Java development. Make sure you are very comfortable with the language and core API classes such as I/O, collections, etc. Do this in a basic Java project in Eclipse.
    Step 3 : Learn JSP and Servlets. These two technologies are the foundation of Java EE web app development. Use "Dynamic Web Project" in Eclipse and Tomcat as your server. For a good exercise, build a web app to manage a catalog of something by reading/writing to a text file local to the server.
    Step 4 : Learn JPA. This is the standard for modern Java database access. Make sure you learn JPA standard rather than a specific implementation like Hibernate. In fact, since you are asking on an Oracle site, I would recommend EclipseLink implementation of JPA rather than Hibernate. For an exercise take your app from Step 3 and make it use a database instead of a file. Use MySQL as your database.
    By the time you get this far you will have a good foundational knowledge of Java EE web development. Where you go from here will depend on your interests. If you are more interested in the web tier, you can learn some of the higher-level front-end technologies such as JSF or Struts that make it easier to build very large apps. If your interests are more in middle tier and scalability, start learning EJBs. Don't bother learning Ant or Maven unless your interests are specifically in build systems and release engineering. You don't need to know Ant/Maven to build/run/export Java EE applications in Eclipse.
    Good luck!

  • Problem with CMP bean and MySQL: please help me!!!

    Hi,
    I am using J2EE Sun server 1.3 and Mysql 4.0 database with its MySQL Connector/J 3.0.
    The driver connection to the database is fine since "Generate Default SQL" in deploytool gives "SQL generation complete".
    However, I can't have a simple row with one text field called test being created in my mysql table called test.
    Of course , the mysql server is started and the test table set for use.
    Here is my code (I try to access my database from a servlet using a CMP Entity bean):
    try{
    Context initial = new InitialContext();
    Object objref = initial.lookup(EntityHome.JNDI_NAME);
    EntityHome home = (EntityHome)PortableRemoteObject.narrow(objref,EntityHome.class);     
    Entity test= home.create("zob");               
    /*EntityHome home = (EntityHome)PortableRemoteObject.narrow(objref,EntityHome.class);     
    catch (Exception ex){                                                                out.println("exception message : " + ex.getMessage()+"</body></html>");}
    I get the following exception message :
    RemoteException occurred in server thread; nested exception is: java.rmi.RemoteException: nested exception is: java.sql.SQLException: Syntax error or access violation, message from server: "You have an error in your SQL syntax.

    I would be very grateful for help since I have a close deadline for this!!!!!!!!
    Thank you very much in advance dear java experts!!!!!!!

  • Having J2EE use mySQL

    Hi
    I'm using a standalone RedHat 9 system with J2EE 1.3.1 and mySQL 3.23.54.
    All are working individually.
    My current application creates new tables every time it starts, so I thought it would be dead simple to just ask J2EE to use mySQL. There are currently only two entity beans, and there's the place in the deploytool to enter the database JNDI name, username and password.
    I can't find any information on how to do it though. What do I enter where? Sun's site doesn't seem to tell me about mySQL and J2EE, while mySQL has not one mention of J2EE in its documentation, nor in Kofler (my mySQL book).
    I looked back through this forum too, and there's a link to a blog that doesn't seem relevant either.
    Clues anyone? Much appreciated. If I see you, I'll buy you a pint. Warm, obviously (I'm in the UK). You'll like it, honest :-)

    Hi! I think I may help you. I had the same problem. But I�m Brazilian, I�m learning the English language yet. I�ll try to explain you.
    I am using J2EE version 1.3 with MySQL version 4.1.7 on Windows. You�ll have to configure the two following files:
    - <J2EE_HOME>\bin\setenv.bat
    - <J2EE_HOME>\config\resource.properties
    1) Copy the Jar file of MySQL driver to <J2EE_HOME>\lib directory.
    2) Open the setenv.bat and edit it. Add a reference to that Jar file.
    3) Run the <J2EE_HOME>\bin\j2eeadmin.bat. There are two command lines to be executed, as below:
    j2eeadmin.bat -addJdbcDriver <CLASS NAME OF THE DRIVER>
    j2eeadmin.bat -addJdbcDatasource <JNDI-NAME> <URL>
    For example:
    j2eeadmin.bat -addJdbcDriver "com.mysql.jdbc.Driver"
    j2eeadmin.bat -addJdbcDatasource "jdbc/mysql-connection/test" "jdbc:mysql://localhost/test?user=username&password=password"
    4) Now, the <J2EE_HOME>\config\resource.properties must be modified, with the reference for the MySQL database. Open this file and you will see. But perhaps you will have to configure it editing this file. That�s because I noticed that the character "\" was added erroneously in a lot of places of the code of this file. It seems to be a bug. So I simply removed this character, replacing it.
    5) Run the verbose, none error must appear, and the MySQL can be used with J2EE now! That�s all. Good luck!

    Hi,

    What's so hard about finding a "best linux distro for installing Oracle11g"? The supported distros are listed in the fine Installation Guide for Linux. At the top of the list is Oracle's own Oracle Linux, which is in the same family as Red Hat.

  • PHP and MySQL Connection problem

    I am trying to make a PHP MySQL on a remote server connection in Dreamwesaver CS3.
    When I enter the information (host, user, password, etc.) and hit TEST, I get the following error message.
    "Access Denied. The file may not exist, or there could be a permission problem. Make sure you have proper authorization on the server and the server is properly configured."
    I know the user, password, etc. work, as I can access the MySQL database with other software.
    I checked with my host and they say there are no permission problems on their end.
    I have checked the settings on the Test Server page in Site Setup and everything looks correct and works there.
    I have not seen this particular problem described in other forum postings (although there are a LOT of postings on this topic!).
    Any help would be appreciated.

    I thought my testing server was the remote server and is always on as far as I know. I don't know how to turn it on or off.
    Is there some other testing server that I should be aware of?

    I know you are using remote, but is your testing server on? if not turn that on and see if that does it. it just happened to me working on remote server and could not get mysql conn to work, until I turn on my testing (developer server), then I was able to connect to mysql and the tables that I created in phpmyadmin remotly was downloaded.

  • How do I add an already built Shopping Cart  (PHP and MYSQL) application to a page in a Muse site?

    How do I add an already built Shopping Cart  (PHP and MYSQL) (Cartweaver 4) application to a page in a Muse site? Do I have to export the Muse site as Html to dreamweaver and them use the extension to bring the shooping cart in or can I do it directly in Muse?
    Message was edited by: mgv2048

    We have experimented with doing this with some good success. We have been working on adding Cartweaver to a Facebook page by essentially adding a Cartweaver store to Facebook in an iframe.  The "store" would be pages with just your basic product display, cart, and checkout functionality, with none of the "window dressing" - just use CSS to match the color and general look of the design it's being added to.
    The one problem with this for Facebook is when it comes time to check out toy have to leave Facebook and go to your server where an SSL is in place.  Fortunately in this situation this would not be the case, you can have an SSL installed to the root of your site and you'll be okay.
    This is an interesting project.  Give this a try and let me know how it goes and if you run into any snags, please make a post on the Cartweaver forums: http://forums.cartweaver.com - I'm really confident that this can work, and not only work, but work well.
    Looking forward to hearing how this goes, and being of what help we can.

  • Slow DataBase Access using JDK 1.5 and MySQL

    Hi EveryBody,
    I am using Jdk1.5 in my project and mysql 5.0 as my database server.
    The problem is that, to create a connection for the first time it takes upto 20 to 25 seconds.
    when i use the 1.4.2 with the same mysql version it takes only 2 seconds.
    In both the cases i am using the JDBC driver (com.mysql.jdbc.Driver )
    I cannot understand the problem with the jdk1.5,
    so, please help me in resoving this issue.

    I encountered same problem with connecting Oralce.
    It's a bug of JDK1.5.
    You need upgrade JDK1.5 to latest version,or use IP address instead of machine name(such as locahost etc.).

  • Deploy Applet and MySQL - how to read and write

    Question on deploying Applet and MySQL
    I am building an applet that is to be a part of a simple game. The applet is supposed to read data from a MySQL server and use it to place towns on the map. In addition, the applet must be able to write to the base.
    I have build a prototype and ran it in netbeans on my computer. It then successfully read data from a local MySQL base. HOWEVER; when I embed the applet in html code it no longer reads from the base. My method for connecting to the base is
    try{
    Statement stmt;
    ResultSet rs;
    Class.forName("com.mysql.jdbc.Driver");
    String url=adress;
    Connection con=DriverManager.getConnection(url, user, user);
    stmt=con.createStatement();
    rs=stmt.executeQuery("SELECT * " +
    "from "+table+" ORDER BY id");
    while(rs.next()){
    get data...
    Town T=new Town(data...); //construct town object
    TL.put(T); //put town objects in an object TownList to use later
    con.close();
    catch(Exception e){
    So;
    1) Why wont the applet read anymore?
    2) Is there a better way to do this? I have heard that its better to connect applets to servlets in some situations. What demands does this place on the server? Is there software that you need to install on the server to use servlets?

    I think I do need an applet. The map I have written permits a lot of features that I dont know how to achieve in another way.
    1) Zooming in and out on mousewheel
    2) Clicking on on two towns gives the distance and by selecting a trooptype one can get information about the traveltime between cities.
    3) Right now, I have a feature to find players or groups of players that are of special interest. It allows a player to submit a list of interesting players. The applet reads this list and provides a button with the players name. If one clicks the name of a player, all his cities flash between their originall color and white (using thread).
    I need java to do this and I need to run it in a webbrowser because there are som parts of the game that is made up of php. So I assume I have to build it as an applet?
