Datasource with Java SE

Is it possible to use a datasource, for example OracleDataSource, with JPA and TopLink, out of an application server (with Java SE)? How to configure in persistence.xml?

Assuming your DataSource works outside of an application server, you could either register it yourself in JNDI, or use a SessionCustomizer in your persistence.xml to configure the DataSource in your TopLink Login.
i.e.
public class MySessionCustomizer implements SessionCustomizer {
public void customize(Session session) {
session.getLogin().setConnector(new DataSourceConnector(myDataSource));
}

  • Datasource works with java code but not with sql:query dataSource=...

    Hello everyone! I have a small problem with binding a DataSource object via JNDI and retrieving it in a web application. This is the case:
    I did not wish to make the DataSource available through the server.xml, because I want to create applications that can be bundled in a simple .war file. So I create the DataSource when the context is created in the contextInitialized() method of ServletContextListener like this:
    InitialContext initialContext = new InitialContext();
    Properties properties = new Properties();
    properties.setProperty( "driverClassName", "com.mysql.jdbc.Driver" );
    properties.setProperty( "factory",   "org.apache.commons.dbcp.BasicDataSourceFactory" );
    properties.setProperty( "username", servletContext.getInitParameter( "dbUser" ) );
    properties.setProperty( "password", servletContext.getInitParameter( "dbPass" ) );
    properties.setProperty( "url",      servletContext.getInitParameter( "dbUrl" ) );
    properties.setProperty( "defaultAutoCommit", "false" );
    properties.setProperty( "maxActive",         "25" );
    properties.setProperty( "initialSize",       "15" );
    properties.setProperty( "maxIdle",           "10" );
    properties.setProperty( "testOnBorrow",      "true" );
    properties.setProperty( "testOnReturn",      "true" );
    properties.setProperty( "testWhileIdle",     "true" );
    properties.setProperty( "validationQuery",   "SELECT 1" );
    properties.setProperty( "removeAbandoned",   "true" );
    DataSource dataSource = BasicDataSourceFactory.createDataSource( properties );
    initialContext.rebind( "daers", dataSource );Please comment if you think this is a bad idea!
    All the above seems to work fine. When I try to retrieve the DataSource in a .jsp file then it all works fine like this:
    <% try {
            javax.naming.InitialContext initialContext = new javax.naming.InitialContext();
            java.sql.Connection conn = ( ( javax.sql.DataSource )initialContext.lookup( "daers" )).getConnection();
            java.sql.Statement statement = conn.createStatement();
            java.sql.ResultSet resultSet = statement.executeQuery("SELECT users.name FROM users;");
            while (resultSet.next()) {
                System.out.println(resultSet.getString(1));
        } catch ( java.sql.SQLException e ) {
            e.printStackTrace();
        } catch ( javax.naming.NamingException e ) {
            e.printStackTrace();
    %>But when I try to execute the same sql query through the appropriate JSTL taglib I get a:
    javax.servlet.ServletException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver"The JSTL code I use is this:
    <sql:query dataSource = "daers" var = "query" scope = "page">
            SELECT users.name
            FROM users
        </sql:query>I do put both of the two above pieces of code in the same .jsp page and the first works but the second causes the exception...
    Any clues..?
    Is it illegal to lookup a DataSource in <sql: dataSource=...> if the DataSource is not registered in the server.xml file..?
    If so, do I have any alternatives (like putting the DataSource as a servlet context variable)..?

    I added a response in your original message:

    Let's keep to it since splitting things across two posts might be confusing.

  • How to set up Tomcat4.1.24 datasource with DB2?

    Hi, Guys:
    I try to set up datasource with DB2. I got a sample, but
    I do not know exactly what some tags mean. Could anyone
    who did this show me an example? Thanks a million!
    For example, what is path? what is docBase? In
    <Resource name="jdbc/DefaultDS", what is jdbc/DefaultDS?
    I am using a servlet to call other java classes which
    access database. How do I specify these in Tomcat?
    server.xml:
    <Context path="/test" docBase="test" debug="0"
    reloadable="false" override="true">
    <Resource name="jdbc/DefaultDS" auth="Container"
    type="javax.sql.DataSource"/>
    <ResourceParams name="jdbc/DefaultDS">
    <parameter><name>user</name><value>scott</value></parameter>
    <parameter><name>password</name><value>tiger</value></parameter>

  • Report With Java

    What is the very best tool for design report for applet?

    The idea of the Java API is to extend the functionality of reports. For example you can define your own specific datasource with that. It's not intended as API to build your complete reports. If your familiar with the xml representation of reports, perhaps it's an option for you to create this xml out of your java programs.

  • Accessing a DataSource with a userid, password.

    I am getting an SQL Exception with trying to create a database connection using a datasource with userid and password, I can log in to the database manually with the credentials but when I try to access via the datasource this is the error returned.
    java.sql.SQLException: java.sql.SQLException: User: doug, failed to be authenticated.
    <code>
    //-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
    // start getConnection
    //-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

    DataSource dataSource = (DataSource) context.lookup("JDBC-GSFP_ResourceTracker");
    return(dataSource.getConnection("doug","root"));
    } // end getConnection
    </code>
    Any Ideas,

    Hi
    When you created DataSource in Weblogic Admin Console, at one point, you will give all the db details like DB Host, port, sid and username/password. You can TEST the connection also right there. If it says success, thats it.
    Now, on the java side, you do Initial context and do JNDI Lookup for that DataSource and directly get the DataSource. There is no need to pass again username/password from Java Side. Just use dataSource.getConnection() without any arguments.
    public Connection getConnection() throws Exception{
    Context context = new InitialContext();
    DataSource dataSource = (DataSource) context.lookup("JDBC-GSFP_ResourceTracker");
    return(dataSource.getConnection());
    } // end getConnection
    Thanks

  • XSLT Mapping with Java class not working in Integration Repository

    Hi,
    I have an XSLT mapping program with Java enhancement and I was able to successfully tested it in Stylus Studio. However, when I imported the Java class and the xslt program in Enterprise Service Builder and tested it, my program does not compile.
    Here is the error message: "Transformer Configuration Exception occurred when loading XSLT mapping_temp.xsl; details: Could not compile stylesheet".
    My java program is in a zip file containing SOAPHeaderHandler.java and SOAPHeaderhandler.class. My Java has a package com.nga.xslt.
    Here is the declaration of my Java class in the XSLT: xmlns:javamap="java:com.nga.xslt.SOAPHeaderHandler"
    It seems that it could not read the java class. Can you please advice what is wrong?

    Hi ,
    select XMLTOOLKIT option in Operation mapping and execute it.
    I am not sure we can call java program in XSLT Program,but alternative is copy the code and use it in XSLT mapping it self,that means your XSLT program will become with JAVA extensions.
    then in Operation mapping level select SAPXMLTOOL kit option and execute it. i hope it will work. if it is not working then you have deploy some JAXP files on server,because the way execution of XSLT Mpaping program got changed,like when eve you executing XSLT with extnasions( if you are not using XMLTOOL kit option) then you have to use latest version of JAXP.JDK files.

    I want to pass along a couple of tips that will get you more and better response on this list.
    1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
    2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
    3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
    4) If you have a question first search the examples for something tha
    t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
    5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
    6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"

  • Problem with java installation on Linux

    HI ,
    I am trying to install jdk on Linux..I am new to java and Linux both. I am trying to download the file for the linux installation onto my home PC(windows XP) and then ftp it to my Linux machine. I need to do this because I have a remote login to my Linux machine( a server at school). However when I try to download file my IE jsut crashes. I can see the page for accepting the Agreement but when I click on Accept the next page just stops responding.
    Could someone explain why this is happening.
    thanks,
    G.

    The problem doesn't have to do anything with Java or Linux as far as i can see. It's more likely a problem with Windows XP and IE. Be assured that normally downloading the Linux JDK in windows is not a problem.

  • Problem with Java and Windows (Mainly Vista and UAC)

    Hi all,
    I am having a problem with a program that I've devoloped. The program itself is packaged as a jar and I plan to deploy it across multiple platforms eventually however right now i am only concerned about windows based systems. I have made an installer for a windows baised systems using NSIS to install the software files. I made the installer as I need several java packages to be installed so the program would work (JAI, J3D, JAI ImageIO) and I also require the program to have fileassociations on windows.
    I know that this is not what java is about, however the majority of the users will be on windows baised systems so I've decided that OS specific installers is the best option.
    During the process I have noticed that there are several key problem with java for this type of application!
    The first issue that I have come across is getting file associations to work on java. As a .jar is not an excutable it is not possible to directly associate a filetype with it in java so to overcome this I currently run the program from a .bat files and also the program requires large memory so this also allows me to run the program with -xmx. The batch file that I use is :
    <code>
    cd PATH TO PROGRAM
    start javaw -Dsun.java2d.noddraw=true -Xmn100M -Xms500M -Xmx1000M -jar "PATH TO PROGRAM\program.jar" %1 -vram 134217728
    pause;
    </code>
    Ok so all this appears to work fine and allows windows to have file associations and start the program and thats all works perfectly but this is a non-ideal solution. Has anyone got any advice on improving this?
    The next problem that I have appears to be a problem with Vista and UAC (user access control). When a user installs the program and installs the program into the program files directory I found that the program did not work and kept saying that I did not have access to the files in the current directory. This is a problem as I read and write settings files during program execution.
    On a Vista system UAC prevents file write operations into the Program Files directory unless the program has requested elevated status even if the user is a full administrator. The probem is that there appears to be no real way to achieve this under java that I'm aware of...
    Has anyone else had this probem and has a suitable solution?
    Any advice on these issues would realy be appricated.
    Regards
    Joey

    Ok so i've kinda found a solution, its not ideal but its very good. I found this program called Elevate
    A link to the site I got it was
    http://www.wintellect.com/cs/blogs/jrobbins/archive/2007/03/27/elevate-a-process-at-the-command-line-in-vista.aspx
    This program allows you start java with a UAC dialog for high access using
    Elevate java -jar myjar.jar
    This then allows you to have full access using java... I guess it could be dangerous but it does the job.

  • Problem with java and flex web service

    Hi,
    I have a basic web service written in java using jax ws 2.1
    ri. I need to call it from Flex using the WebService class
    Annotations for the java web method :
    @WebMethod
    public void Login(
    @WebParam(name="server") String serverURL,
    @WebParam(name=AUTHENTICATE_HEADER,header=true,mode=WebParam.Mode.INOUTHolder<Authenticate Header>
    authHeader)
    When I try and call the service from Flex , it can't find the
    login method and attempts to call it fail. If I set the web service
    to RPC based using @SOAPBinding , the method is found but then
    there are issues with the authentication header.
    What do I need to do to get flex web services communicating
    succesfully with java ?
    Are there are any known compatibility issues ? Or guidelines
    for going about this ?
    Any help would be appreciated

    well Shay,
    i've used JDev's tools to developer and to deploy the web service: the war and ear files are automatically generates you to the end of the process.
    I have included all the files java and the compiled classes, but I do not have files jar.
    But don't works: if i create only one java class with all code inside then it works fine!!

    So here is what comes to pass.
    Recall this started as a Lion Safari/5+ environment that SU took to version 6.
    Two weeks ago I just updated Flash Player. Today I fire up Java Preferences and I am told that I need to download Java. Did so, intentionally hit the "factory reset" button and then installed the Flash Player from teh Adobe site. The most recent install suggests automatic update but I choose "ask first."
    Restart Safari and we seem to be in order
    Thanks

  • Problem with java swing button and loop

    Problem with java swing button and loop
    I�m using VAJ 4.0. and I�m doing normal GUI application. I have next problem.
    I have in the same class two jswing buttons named start (ivjGStart) and stop (ivjGStop) and private static int field named Status where initial value is 0. This buttons should work something like this:
    When I click on start button it must do next:
    Start button must set disenabled and Stop button must set enabled and selected. Field status is set to 1, because this is a condition in next procedure in some loop. And then procedure named IzvajajNeprekinjeno() is invoked.
    And when I click on stop button it must do next:
    Start button must set enabled and selected and Stop button must set disenabled.
    Field status is set to 0.
    This works everything fine without loop �do .. while� inside the procedure IzvajajNeprekinjeno(). But when used this loop the start button all the time stay (like) pressed. And this means that a can�t stop my loop.
    There is java code, so you can get better picture:
    /** start button */
    public void gStart_ActionEvents() {
    try {
    ivjGStart.setEnabled(false);
    ivjGStop.setEnabled(true);
    ivjGStop.setSelected(true);
    getJTextPane1().setText("Program is running ...");
    Status = 1;
    } catch (Exception e) {}
    /** stop button */
    public void gStop_ActionEvents() {
    try {
    ivjGStart.setEnabled(true);
    ivjGStart.setSelected(true);
    ivjGStop.setEnabled(false);
    getJTextPane1().setText("Program is NOT running ...");
    Status = 0;
    } catch (Exception e) {
    /** procedure IzvajajNeprekinjeno() */
    public void IzvajajNeprekinjeno() {  //RunLoop
    try {
    int zamik = 2000; //delay
    do {
    Thread.sleep(zamik);
    PreberiDat(); //procedure
    } while (Status == 1);
    } catch (Exception e) {
    So, I'm asking what I have to do, that start button will not all the time stay pressed? Or some other aspect of solving this problem.
    Any help will be appreciated.
    Best regards,
    Tomi

    This is a multi thread problem. When you start the gui, it is running in one thread. Lets call that GUI_Thread so we know what we are talking about.
    Since java is task-based this will happen if you do like this:
    1. Button "Start" is pressed. Thread running: GUI_Thread
    2. Event gStart_ActionEvents() called. Thread running: GUI_Thread
    3. Method IzvajajNeprekinjeno() called. Thread running: GUI_Thread
    4. Sleep in method IzvajajNeprekinjeno() on thread GUI_Thread
    5. Call PreberiDat(). Thread running: GUI_Thread
    6. Check status. If == 1, go tho 4. Thread running: GUI_Thread.
    Since the method IzvajajNeprekinjeno() (what does that mean?) and the GUI is running in the same thread and the event that the Start button has thrown isn't done yet, the program will go on in the IzvajajNeprekinjeno() method forever and never let you press the Stop-button.
    What you have to do is do put either the GUI in a thread of its own or start a new thread that will do the task of the IzvajajNeprekinjeno() method.
