Problem in using MySQL in JSF Pages

Hi,
I am facing a problem regarding use of MySQL in JSF.
I am using IBM RAD 6.0 for application developement.
Previously creating a normal java application which is used of retrieval of the data from the database was working fine. by including j/connector jar file in java build path.
But when same program is converted to web service and accessed through a JSF page using a managed bean it is not working. It throws classNotFoundException
Please reply at your earliest.
Thanks in advance.
Regards,
Amit
code :-
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class BeanClass
     public String display()
          Connection conn = null;
          Statement stmt = null;
          ResultSet rs = null;
          String returnDate = "";
          try
               Class.forName("com.mysql.jdbc.Driver").newInstance();
               System.out.println("Sucess");
               conn=DriverManager.getConnection("jdbc:mysql://localhost/switching","root","pspl");
               System.out.println("Sucess******");
               stmt = conn.createStatement();
               System.out.println("Sucess^^^^^^^^^");
               rs = stmt.executeQuery("SELECT * FROM log1 where senderId = '008' ");
               System.out.println("Sucess#########");
               while(rs.next())
                    System.out.println("Date : " + rs.getString("expDate"));
                    returnDate = rs.getString("expDate");
               System.out.println("Final success");     
               System.out.println("Sucess@@@@@@@@@@@@@@@@");
          }catch(ClassNotFoundException cnfe)
               System.err.println("Drivers not found " + cnfe.toString());
               cnfe.printStackTrace();
          catch(IllegalAccessException iae)
               System.err.println("Access Exception");
          catch(InstantiationException ie)
               System.err.println("Instatiation Exception");
          catch(SQLException se)
               System.err.println("SQL EXCEPTION");
               se.printStackTrace();
          System.out.println("Date is = " + returnDate);
          return returnDate;
Errors are :-

  • Using workflow from jsf pages...

    We have built a simple JSF page on OC4J app server..
    We want to call our workflow program from this page.
    How should I use the CREATE PROCESS() AND START PROCESS() inside the JSF page?
    We are using 10.1.2. application server. And We SSO connection between
    OC4J 10 1. 3.2
    we deploy our java application to this OC4J..
    But we when we call workflow functions we get get_remote_user error.
    Can we call direct PL/SQL API over JDBC connection without using OWF Java API.
    Or we need (must) use Java aPI to supply this.
    Thanks...

    We see that we can call CREATE PROCESS() OR START PROCESS() inside the JSF page..
    But the problem are about notifications which needs authentication now

  • Navigation problem when using tiles with JSF

    Hi all,
    I m using tiles with JSF. i have included all the libraries and jsp page is rendered properly. but when i use <h:commandLink> in the body part of the JSP , i cannot go to the specified link. when we use tiles, what changes need to be done in faces-config file?? i mean what navigation rule we need to specify ??

    Hello, I have the same problem; JSF+Tiles = No navigation.
    One basic question is should I reference the parent jsp or the included body jsp in the faces-config.xml file.
    For example: The login.jsp is a main tiles page that includes a menu.jsp, header.jsp & a loginBody.jsp.
    Hence the faces-config could have this rule;
    <navigation-rule>
    <from-view-id>/login.jsp</from-view-id>
    <navigation-case>
    <to-view-id>/catalog.jsp</to-view-id>
    </navigation-case>
    </navigation-rule>
    (I've left the outcome tag out to simplify this post)
    Or, I could refer loginBody.jsp in the navigation rule;
    <navigation-rule>
    <from-view-id>/loginBody.jsp</from-view-id>
    <navigation-case>
    <to-view-id>/catalog.jsp</to-view-id>
    </navigation-case>
    </navigation-rule>
    The loginBody.jsp has a commandbutton which a user clicks which starts the navigation.
    Neither seems to work unfortunately & I'm a stuck.
    Thanks

  • Howto use comments in JSF pages

    Hi all,
    I play a little bit with JSF, at the moment. I wonder that I cannot find any information about how to comment out a part of a JSF page, that it is not rendered.
    If I use the html comment tags <!-- --> then this part is already rendered if I access the page.
    If I want to comment out an invalid part, the execution will fails :(.
    So is there a comment tag in JSF, which is not be rendered if a page is access?
    Thank in advance
    Marco

    I'm sure you must have found a way by now, but to anyone who also has this problem (like myself :D) you can do the following.. I'm using Facelets as XHTML pages, and I didn't find a way of allow the JSP style comments:
    <%--    --%>But if you add the below to your web.xml, you can allow Facelets to skip HTML comments:
    <context-param>
        <param-name>facelets.SKIP_COMMENTS</param-name>
        <param-value>true</param-value>
      </context-param>So with the above in your web.xml, the below:
    First line: #{person.id}
    <!-- Second Line: #{person.id} -->would generate, assuming the person bean's id property is 5:
    First line: 5

  • CachedRowSet.next() problem.  Using mysql.

    Hello,
    I'm trying to retrieve the results of a database query using a CachedRowSet but the next() function doenst resolve for me.
    I'm using intellij with sun java 1.5.0.06 and mysql-connector-java-3.1.12-bin.jar.
    I've also tried mysql-connector-java-5.0.3-bin.jar but get the same problem.
    Here is the code snippet:
        CachedRowSet crs = LinkerAdapterMySQL.getInstance().getData( "SELECT * FROM restype WHERE 1" );
        Vector<String> resTypes = new Vector<String>();
        while( crs.next() )
            try{
            resTypes.add( crs.getString( "resType" ) );
            } catch( java.sql.SQLException e )
                System.err.println( e.toString() );
        }When i try to build the project i get this error at the line "while( crs.next() )":
    illegal start of type.
    Any ideas what's going on?
    thanks.

    Whoops, nevermind.
    I'm an idiot and had that code outside of a function declaration.

  • Using arrays in a jsf page

    Hi guys,
    I'm developing an ADF application in JDev 11.1.1.6.0. I have problem about using arrays in jsp page. I have an iterator that brings me data from UCM. I just want to take every documents seperately and use in a Jquery division by division.
    Can i have chance to use an array tag in that page? Or how can i make it possible my work in a different way?
    Thank you so much,
    Erdo

    Hi Frank,
    I've already use an iterator. I just want to take datas and after close the af:iterator tag. Then i will use those datas in a different block.
    My code :
    <af:iterator var="node" value="#{nodes}" id="i1">
    <af:outputText value="#{node.propertyMap['CSGMNEWS_REGDEF:Desc'].asTextHtml}"
    id="ot1"/>
    </af:iterator>
    I want to take all informations from node.PropertyMap[] and then i will set the values of outputText with those informations. I hope I'm clear.
    Regards,

    I think that I don't load. But I don't know where I write the below line.Than it's clear that you'll get a NullPointerException.
    But I don't know where I write the below line.
    Context context = new InitialContext();
    this.propiedadesBean = (LocalPropiedades)
    context.lookup("inmovil/propiedadesLocal/local");Whenever you need it. For example within an ActionHandler which loads the bean
    and makes a DTO Object (Bean used by the JSF Page) available for the JSF Page.
    But where you actually have to load the Bean depends on your design.

  • Using expressions in jsf tags

    I have a problem with using expressions in jsf tags! I know this
    topic was discussed before but it doesn`t work.
    I want to use the following jsf-code:
    <h:panel_data id="tab" var="vari" modelReference="Bean.varis">
    <h:output_text id="Id" modelReference="vari.id"/>
    <h:command_hyperlink id="hyper" href="next.jsp" label="Detail">
    <f:parameter id="Param1" name="id" value="vari.id"/>
    </h:command_hyperlink>
    </h:panel_data>
    The value of the parameter should have the value of vari.id!! Why doesn`t it work?? I also tried to use value="${vari.id}" and value=<%= vari.id %>.
    I have also changed the jsf_core.tld from
         <rtexprvalue>false</rtexprvalue>
    to
         <rtexprvalue>true</rtexprvalue>
    Does anybody know what to do? Where should the .tld-files be localized when i deploy the webapplication??

    If you want your parameter's value to be pulled from the model, you must
    use modelReference instead of value. Try that and see if it works.

  • I am developing a Web App which will have millions of users. I am expecting to use MySQL & Microsoft SQL. Is there any issue with doing that?

    I am developing an app that will server millions of users. Most of the information coming out of the database won't be of any security concern, but there will be some accounts with financial information that I want more secure. For money reasons, I am
    looking at using MySQL for the majority of the Web app and then when I am using a secure connection for money things, using Microsoft SQL Server. Is there anything wrong with that idea?
    DCSSR

    I understand the confusion. I don't want the expense of Microsoft SQL server and was thinking that if I left everything that didn't need to be secure in MySQL, then I could use Microsoft SQL Server free (less than 10 GB) for just billing where security
    is more of an issue for me.  It might just be me, but I feel more vulnerable using MySQL.
    Should I not feel that way?
    DCSSR
    This is wrong and it is not not professional to throw recommendations regarding a specific system design , while we do not know your system characterization (which is something you can not post in a forum). What we do here is mostly helping in specific question
    or just throw comments and general points based on golden rules (rules of thumb). as i wrote before I see no reason of using both MySQL and SQL Server and the new information did not change this.:-)
    I can not tell how you should feel, as I dont know you or your system and most important I do not know your developers knowledge/ability. I can tell you that there is no problem in using MySQL regarding security if you do it in the right way. I can tell
    you that I would feel great with working with MySQL regarding security (By personally i prefer SQL Server).
    * You can think on using NoSQL (as well as MySQL) if u need free database server if the size limitation of 10 GB is the problem. You can use flat database as well for some data.
    * If the problem is using 20 GB then I will prefer in most cases to use 2 databases from the same type on using 2 different database server. In this case where I have to choose between using SQLEXPReSS+MySQL or 2 SQLEXPRESS i will probably prefer 2 SQL
    EXPRESS databases (in 2001 I had a system with more then 20k users using several MS-ACCESS as databases... It worked great).
    I hope this is useful :-)

  • Problem with opening PDF files from JSF page using SDO

    Hi all,
    I'm new with JSF and was attempting to read a PDF file from a Database using SDO and JSF. The code below throws an exception when casting from DataObject to Blob. The getLcDoc() method was created by WSAD when I dragged an SDO relational record onto the JSF page. This method returns an DataObject type which I tried casting to a Blob type before using it further. However, an exception is thrown.
    Any feedback is appreciated.
    Arv
    try {
                   FacesContext faces = FacesContext.getCurrentInstance();
                   HttpServletResponse response =(HttpServletResponse) faces.getExternalContext().getResponse();
                   Blob file= (Blob)getLcDoc().get("ATTACH");
                   int iLength = (int)(file.length());
                   response.setHeader("Content-type", "application/pdf");
                   response.setHeader("Content-Disposition", "inline; filename=Attachment");
                   response.setHeader("Expires","0");
                   response.setHeader("Cache-Control","must-revalidate, post-check=0, pre-check=0");
                   response.setHeader("Pragma","public");
                   response.setContentLength(iLength);
                   ServletOutputStream os = response.getOutputStream();
                   InputStream in = null;
                   in = file.getBinaryStream();
                   byte buff[] = new byte[1024];
                   while (true) {
                   int i = in.read(buff);
                   if (i<0) break;
                   os.write(buff,0,i);
                   os.flush();
                   os.close();
         } catch(Exception ex){
              System.out.println("Error while reading file : " + ex.getMessage());
         }

    Hi...I found out that there is actually no need to use a Blob object at all. You can simply call the OutputStreams write() method and pass the DataObject.getBytes() method that returns a byte[] array. The revised code is shown at the end of this posting.
    However, a few other teething problems exist:
    1. This works well only if I specify the content type in response.setHeader() method. What if my users upload different types of files, is there a way that the browser opens according to the file type without setting the content type?
    2. I still have a problem opening PDF files, even if I specify - response.setHeader("Content-type", "application/pdf");
    I get the message - The file is damaged and could not be repaired
    3. I would also like this to open the attachment in a new window and using target="_blank" doesn't seem to work as seen below:
    <h:commandLink
                                                 styleClass="commandLink" id="link1" action="#{pc_DocumentDetailsRead.doLink1Action}" target="_blank">
                                                 <h:outputText id="text5" styleClass="outputText"
                                                      value="Click Here"></h:outputText>
                                            </h:commandLink>
    ------------------------Revised code-----------------------------------------
    FacesContext faces = FacesContext.getCurrentInstance();
                   HttpServletResponse response =(HttpServletResponse) faces.getExternalContext().getResponse();
                   response.setHeader("Content-type", "application/msword");
                   response.setHeader("Content-Disposition", "inline; filename=Attachment");
                   response.setHeader("Expires","0");
                   response.setHeader("Cache-Control","must-revalidate, post-check=0, pre-check=0");
                   response.setHeader("Pragma","public");
                   ServletOutputStream os = response.getOutputStream();
                   os.write(getLcDoc().getBytes("ATTACH"));
                   os.flush();
                   os.close();

  • Serious problem of jdbc-mysql connectivity using tomcat

    hi everybody
    i m in serious problem since last 15-20 days. i m trying hard to make the connection jdbc-mysql using tomcat with the help of a jsp test page but every time i am facing almost the similar probems listed below in detail:
    to make sure that the jdrivers's .jar (mysql-connector-java-3.1.7-bin.jar) available for such connections working fine i have tried the above said connection without using tomcat....which is working fine...for this i have created a dummy database with a dummy table ..and written some queries in the .java file of my code which upon running inserts the specified values in the defined(dummy) database.
    this is the confirmation that the classpath etc..are ok in regard to the mysql-connector-java-3.1.7-bin.jar
    now i have placed a copy of this .jar file in to the commons/lib directory of the tomcat web server(which is suppossed to be the place for such external jars)
    after doing so i have followed 2 methods :
    method 1st:........
    i have made aone more jar file from the following .java file....
    import javax.naming.*;
    import javax.sql.*;
    import java.sql.*;
    public class TestSQLLoad
    String user = "Not Connected";
    String pwd = "no pwd";
    int id = -1;
    public void init() {
    try{
    Context ctx = new InitialContext();
    if(ctx == null ) {
    throw new Exception("Boom - No Context");
    DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
    if (ds != null) {
    Connection conn = ds.getConnection();
    if(conn != null) {
    user = "Got Connection "+conn.toString();
    Statement stmt = conn.createStatement();
    String q = "select name, password, id from user";
    ResultSet rst = stmt.executeQuery(q);
    if(rst.next()) {
    user=rst.getString(1);
    pwd=rst.getString(2);
    id = rst.getInt(3);
    conn.close();
    }catch(Exception e) {
    e.printStackTrace();
    public String getUser() {
    return user;
    public String getPassword() {
    return pwd;
    public int getID()
    return id;
    after compiling it at the cmd prompt i made a .jar file from the .class of it and named it MySQLLoad.jar...then i placed it also in to the commons/lib directory where the mysql-connector-java-3.1.7-bin.jar was already placed.
    then i have changed the server.xml and web.xml files from the conf directory of the tomcat as given here:
    server.xml
    <!-- Example Server Configuration File -->
    <!-- Note that component elements are nested corresponding to their
    parent-child relationships with each other -->
    <!-- A "Server" is a singleton element that represents the entire JVM,
    which may contain one or more "Service" instances. The Server
    listens for a shutdown command on the indicated port.
    Note: A "Server" is not itself a "Container", so you may not
    define subcomponents such as "Valves" or "Loggers" at this level.

    after all this i have taken a jsp page whose code is here:
    (the mysql database used is named as "testdb" and the table name is "user" which is having fields name,password and id)
    <html>
    <head>
    <title>DB Test</title>
    </head>
    <body>
    <%
    TestSQLLoad tst = new TestSQLLoad ( );
    tst.init();
    %>
    <h2>Results</h2>
    User <%= tst.getUser() %>
    Pwd <%= tst.getPassword() %>
    Id <%= tst.getID() %>
    </body>
    </html>
    and placed it in to the Tomcat 5.5\webapps\tomcat-docs\testdb directory and saved as test-db.jsp
    when i run this page on the browser i get a lot may errors stating
    org.apache.jasper.JasperException: Unable to compile class for JSP
    An error occurred at line: 12 in the jsp file: /testdb/test-db.jsp

    note The full stack trace of the root cause is available in the Apache Tomcat/5.5.4 logs.
    AND NOW WHEN just to get rid of such errords i try to include a statement
    <%@ page import="pkg.TestSQLLoad" %> in the jsp page code (and also place the MySQLLoad.class file in a folder called pkg and place it in the same directory where the jsp page is )and make it look like
    <html>
    <head>
    <%@ page import="pkg.TestSQLLoad" %>
    <title>DB Test</title>
    </head>
    <body>
    <%
    TestSQLLoad tst = new TestSQLLoad ( );
    tst.init();
    %>
    <h2>Results</h2>
    User <%= tst.getUser() %>
    Pwd <%= tst.getPassword() %>
    Id <%= tst.getID() %>
    </body>
    </html>
    now when i run it i get the following errors:
    exception
    org.apache.jasper.JasperException: Unable to compile class for JSP

    in response to the above error i have even tried placing the MySQLLoad.class directly in the testdb folder along with the jsp page without keeping it in a package named pkg and then importing directly as <@page import="MySQLLoad" %>
    that too gave me the following errors

    and if i do not use the statement <%@ page import="MySQLLoad"%> then also i get the errors like

    THE 2nd Method:
    in my second method i did the same changes in the web.xml and server.xml
    then i took a jsp page with the following code:

    Connection conn=dataSource.getConnection();
    Statement stmt=conn.createStatement();
    ResultSet rset=stmt.executeQuery("select * from user");
    if (rset.next()){

  • How to Use another JSF page that I load by XMLHttpRequest?

    Hi everyone, I'm a newbie of JSF and curisous about how to load page content seperately by AJAX.
    I saw example of Java Blue Print. It's load some data to use in page. What I want is to load another JSF page when click a link or button, (Like include another page). And work with functions privoided by loaded JSF Page.
    My example is, In a main page. I request a JSF page and set it into a div layer.
    var requestURL = "/admin/customer/customer-list-body.faces";
    var content = postDataWithoutContent(requestURL);     divContent.innerHTML = content;     
    All JSF components are required under <f:view>, thus action of form is set as "action='"/admin/customer/customer-list-body.faces'"
    But my page is main.jsp. Each time I click command button in customer-list-body.faces, the url will change to customer-list-body.faces, I want to request and hold in main.jsp.
    What can I do then? Any advices?

    Hi,
    the list doesn't seem to be your problem. You need to track down the illegal argument exception. Once you have that sorted out, expose the method on the AM so it gets shown as a method binding. The return values then could be picked up in a managed bean to create the select Item list
