Servlet-jdbc problem

hello all,
I am writing a simple servlet which will extract data (empno and empname) from a html form and insert in to database.
everything seems to work fine except it inserts in to the table empno and empname as it is without values.
if u can think of some reason and specify it would be great.
thanx once again.
mahesh
anyway i have those 2 small programs as below :
enterinfo.java - for generating entry form
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class EnterInfo extends HttpServlet
     public void service(HttpServletRequest req,HttpServletResponse res) throws ServletException,IOException
          res.setContentType("text/html");
          PrintWriter out=res.getWriter();
          out.println("<html><body>");
          out.println("<form name=\"insertdata\" method=\"post\" action=\"msgservlet\">");
          out.println("Emp No<input type=text name=empno><br>");
          out.println("Emp Name<input type=text name=empname><br>");
          out.println("<input type=submit value=send>");
          out.println("</form></body></html>");
msgservlet.java - for extracting data and inserting data in to the table
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class msgservlet extends HttpServlet
     private Connection con;
     private PrintWriter out;
     private Statement stmt;
     public void init(ServletConfig conf) throws ServletException
          super.init(conf);
          try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          catch(ClassNotFoundException cnfe)     
               System.err.println("Details:"+cnfe);
               System.exit(0);
          try
               conrjc();
               //con=DriverManager.getConnection("jdbc:odbc:njdbc");
          catch(SQLException sqle){
          System.err.println("Details"+sqle);
     public void conrjc() throws SQLException
          con=DriverManager.getConnection("jdbc:odbc:njdbc");
     public void service(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException{
          res.setContentType("text/html");
          try{
               out=res.getWriter();
               out.println("<html>");
               out.println("<head>");
               out.println("<title>Sample JDBC Servlet</title>");
               out.println("</head>");
               out.println("<body>");
               stmt=con.createStatement();
               int eno=Integer.parseInt(req.getParameter("empno"));
               String enm=req.getParameter("empname");
               //String ins="insert into MYEMPLOYEE values('req.getParameter("empno")','req.getParameter("empname")')";
               stmt.executeUpdate("insert into MYEMPLOYEE values(eno,enm)");
               out.println("<h1>OK</h1>");
//               stmt.close();
               con.commit();
          catch(SQLException se){
          out.println("An SQL Exception was Thrown"+ se);
          catch(IOException se){
          out.println("An IO Exception was Thrown");
          out.println("</body>");
out.println("</html>");
          out.close();          
          public void destroy(){
          try{
               con.close();
          catch(SQLException sqle){}

try using the following statement instead on the previous one...
stmt.executeUpdate("insert into MYEMPLOYEE values('"+eno+"','"+enm+"')");
Usually strings are passed as 'string' to be inserted into the database. Make sure you know what data type you are inserting into the database (from database design). However, prepared statement should work as well.
Hope this helps

  • JDBC Problem with Netscape Enterprise Server 3.61

    I have created a servlet->JDBC(Thin driver for Oracle 7.3) model to communicate the ORacle Database on an UNIX box by using Netscape Enterprise Server 3.61. I got the following problems and if anyone could help me. Many many thanks.

    By the way. This model works fine on the servletrunner on my NT machine and I guess there are some problem on the Nescape Server setting.

    You need to install the Netscape Proxy plug-in.
    You can find the plug-in at the BEA download site along with the instructions.
    Once downloaded it took about 5 minutes to update a config file and have everything running.
    Good Luck...

    Hi,
    I am just starting to learn servlets and I got problem in compiling them. I got compilation error in

  • Servlets/JDBC vs. servlets/EJB performance comparison/benchmark

    I have a PHB who believes that EJB has no ___performance___ benefit
    against straightforward servlets/JSP/JDBC. Personally, I believe that
    using EJB is more scalable instead of using servlets/JDBC with
    connection pooling.
    However, I am at a lost on how to prove it. There is all the theory, but
    I would appreciate it if anyone has benchmarks or comparison of
    servlets/JSP/JDBC and servlets/JSP/EJB performance, assuming that they
    were tasked to do the same thing ( e.g. performance the same SQL
    statement, on the same set of tables, etc. ).
    Or some guide on how to setup such a benchmark and prove it internally.
    In other words, the PHB needs numbers, showing performance and
    scalability. In particular, I would like this to be in WLS 6.0.
    Any help appreciated.

    First off, whether you use servlets + JDBC or servlets + EJB, you'll
    most likely spend much of your time in the database.
    I would strongly suggest that you avoid the servlets + JDBC
    architecture. If you want to do straight JDBC code, then it's
    preferable to use a stateless session EJB between the presentation layer
    and the persistence layer.
    So, you should definitely consider an architecture where you have:
    servlets/jsp --> stateless session ejb --> JDBC code
    Your servlet / jsp layer handles presentation.
    The stateless session EJB layer abstracts the persistence layer and
    handles transaction demarcation.
    Modularity is important here. There's no reason that your presentation
    layer should be concerned with your persistence logic. Your application
    might be re-used or later enhanced with an Entity EJB, or JCA Connector,
    or a JMS queue providing the persistence layer.
    Also, you will usually have web or graphic designers who are modifying
    the web pages. Generally, they should not be exposed to transactions
    and jdbc code.
    We optimize the RMI calls so they are just local method calls. The
    stateless session ejb instances are pooled. You won't see much if any
    performance overhead.

  • Ias support for EJB, JSP/servlets,JDBC, connection pooling, XML, SOAP, load balancing etc

    Please let me know where I can find more information regarding iPlanet usage/deployment/configuring/tuning etc for support of technologies - like EJB, JSP/servlets, JDBC, connection pooling, XML, load balancing, JDBC & Transactions
    (I have already read the 'Getting Started with the iPlanet Application Server' part five and six - http://developer.iplanet.com/appserver/testdrive/partfive.jsp and partsix.jsp)(I am using the ias testdrive version).

    Hi,
    It's difficult to explain unless the J2EE architecture is understood. Also, explaining things like load balancing, Transactions, tuning, are bit vague and could blow the disk space of this site.
    To get started, the best way is to test the sample applications and the best part is you don't require internet connection to follow each steps. Install iWS and iAS, open browser, type in http://hostname:port/ias-samples/index.html. You can find links to the sample applications bundled. Please follow the steps given on deploying the application. This will enable you to a higher level.

    Hi,

    Web Server : Netscape Enterprise Server
    Database : Oracle 8i
    JDK2 and JSDK2 installed on the Server.

    To run servlets you must have a special server to run them like JRun or Java Web Server visit www.allaire.com to download JRun
    You must also download the servlet.jar

    you must configure your CLASSPATH too

    We have been troubleshooting a problem with our recently installed Linux (mandrake 8.0) Oracle DB Server. Everything seems to run fine, except JDBC connections. Whenever we connect to the server with one of our Java applications, JSP, Servlet, etc... the first time it works, then all other java apps get:
    java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
    ... also, our connect strings are correct... seems to be a problem with the listener...
    this only happens on the linux server and not solaris.
    Here is the listener.ora file
    # LISTENER.ORA Network Configuration File: /disk1/OraHome1/network/admin/listener.ora

  • Java servlets - JDBC

    hi,
    I have a problem... i would like to fetch some strings from the database using JDBC and create a tree structure using java servlets to be displayed on a browser using html.
    Currently i have tried using a hashtable as well as defaultmutabletreenode, both of which grew complicated and did not give the desired results.
    Pls help...

    I tried using both a DefaultMutableTreeNode
    containing all the other nodes as child nodes and a
    hashtable with a series of internal hashtables -- and
    passed it to the servlet displaying the html
    l content.
    Is there a better/simpler data structure to use in
    this case other than a Hashtable and a
    DefaultMutableTreeNode?How should we know? You're asking what is better to solve your problem, without saying what your problem is. (Hint: "I can't do this" or "It doesn't work" are not useful problem descriptions.)
    If I were doing this, and if I had to build a tree structure in memory before producing HTML from it, I would use DefaultMutableTreeNode. But then I don't know anything about your problem.

  • Jsp-servlet-bean problem

    Please help!
    I have a servlet controller, a javabean for the data and a jsp for the view.
    I cannot get the jsp using
    <jsp:useBean id="pList" class="bbs.PostListCommand" scope="request" />
    to access the bean data
    However, when I access the bean in this way
    <%@ page import="bbs.PostListCommand" %>
    // html
    <% bbs.PostListCommand postList = null;
    synchronized(session){
         postList = (bbs.PostListCommand) session.getAttribute("PostListCommand");
         if (postList == null){ %>
              <H1>Nothing in request scope to retrieve ....</H1>
              <P>
    <%     }
         else{  %>
              <TABLE border="1">
    // etc
    � it works
    Does anyone know why the <jsp:useBean> tag does not find the bean
    I have installed tomcat 4.18 and set the environmental variables etc.
    Directory structure is
    E:\Tomcat41\webapps\examples\WEB-INF\jsp          for jsp�s
    E:\Tomcat41\webapps\examples\WEB-INF\classes\bbs     for bean and servlets
    Thanks in advance for any help.
    Chris

    GrayMan - Thanks for your help.
    Let me explain my problem in more detail ...
    Background:
    I have some servlet experience, but I am new to jsp - so sorry if this seems trivial to you ...
    I have a book called bitter java by bruce tate from manning.com . I am trying to get the chapter 3 examples to work
    There are three files
    PostListCommand          the bean
    PostListController     the servlet
    PostListResults          jsp
    And a new test file � PostListResults version 2 with scriptlet code to access the bean.
    There are a couple of typos in the downloaded source files, but nothing that causes the main problem of not being able to access the bean data.
    Program flow
    Servlet instantiates new bean
    Bean � gets data from db
    Servlet passes bean to jsp with a forward
    Jsp outputs data
    I have put the files in the directories �
    E:\Tomcat41\webapps\examples\WEB-INF\jsp          for jsp�s
    E:\Tomcat41\webapps\examples\WEB-INF\classes\bbs     for bean and servlets
    The complete source code for each file is given below.
    1 I have checked the db access � that�s ok
    2 I have also checked reading the bean data back in from the request scope and printing out the results from within the servlet.- ok
    3 I can access the data through a scriptlet (PostListResults version 2), but not with the original PostListResults which uses <jsp:useBean>
    thanks in advance, chris

  • Distributed transactions/jdbc problem WL60

    Hi
              Our company has aworking application running on WLS5.1sp9.
              Im in the process of migrating it to WL6.0sp2.
              Our domain has 2 clusters each running 2 servers:
              1) servlet engines (handling http requests from clients, running servlets
              and jsp's)
              2) ejb containers (runnigour entities and session beans, working with Oracle
              8i database using connection pool and TxDataSource)
              The scenario:
              - a client request invokes a servlet on one of the servlet engines.
              - the servlet opens a jndi context to one of the ejb containers
              - the servlet open a transaction on a UserTransaction stub on that ejb.
              - then the servlet calls an entity bean using a home interface looked up
              using the same context.
              - the entity bean uses DataSource lookup in its own servers jndi to rerieve
              a connection.
              and then i get the following exception:
              java.sql.SQLException: No default driver for database type:
              jdbc:weblogic:jts
              at
              weblogic.jdbcbase.t3.Driver.seeIfWeNeedToInferDriverNameAndUrlFrom(Driver.ja

              :44)
              at com.unisfair.util.DBHelper.getConnection(DBHelper.java:43)
              the transaction toString() gives:
              transaction=(IdHash=7541556,Name = [EJB
              UserBeanImpl.generateSessionSuffix()],Xid=2:b53da78d3c1badbb,Status=Active,n

              ned=none),SCInfo[ejb2]=(state=active),SCInfo[servlet2]=(state=active),SCInfo
              [ejb1]=(state=active),properties=({weblogic.transaction.name=[EJB
              UserBeanImpl.generateSessionSuffix()], weblogic.jdbc=t3://10.0.0.31:7007}))
              However the error happens on the other ejb server 10.0.0.33:7007
              It seems that the jts driver tries to get a remote connection on the server
              that coordinates the transaction but uses the deprecated t3 driver.
              I hope someone can help us since this problem is a good enough reason for us
              not moving on to WL6.0 we also looked at WL6.1 Beta and theres nothing new
              about it either.

    <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDBC_TX ():
    In the readme file of Oracle JDBC drivers 8.1.6.0.1 (http://technet.oracle.com/software/tech/java/sqlj_jdbc/files/Readme_01.txt)
    it mentioned that it supports "distributed transactions".
    As I understand, JDBC transaction is connection based and uses Oracle internal transaction manager. In order to do "distributed transactions", I must have at least two connections open at the same time each to its own database instance. How does the two connections coordinate the transactions? I thought in order to support "distributed transactions", one has to build a higher layer to encapsulate the two connections and therefore coordinate the distributed transactions. Any examples will be welcome.<HR></BLOCKQUOTE>
    The two branches of the transaction are coordinated using 2-phase commit.

  • Informix JDBC Problem

    Hi!
    We're using Informix 7 + WL6sp1 + Informix JDBC Driver v2.2. We have a connection
    pool and connect to the pool using:
    Driver myDriver = (Driver) Class.forName("weblogic.jdbc.pool.Driver").newInstance();
    con = DriverManager.getConnection("jdbc:weblogic:pool:poolname");
    The problem is as follows:
    Every time we modify a stored procedure (DROP ... CREATE ...) our app fails when
    trying to use that stored procedure. We have to shut down the server and restart
    it in order to keep going.
    The stack trace:
    java.sql.SQLException: SPL routine(disponibilidad_hot) is no longer valid.

    It happens because weblogic caches prepred statements.
    Though the name of the stored procedure remains the same,
    it's a different object from the database point of view, which is
    why a mismatch between cache and database occurs.
    You may consider setting size of the prepared statement
    cache to zero. That should solve the problem. Later, when
    the SP code is stabilized, you will be able to turn in on back.
    Regards,
    Slava Imeshev

    Hi!
    We're using Informix 7 + WL6sp1 + Informix JDBC Driver v2.2. We have aconnection
    pool and connect to the pool using:
    Driver myDriver = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
    con = DriverManager.getConnection("jdbc:weblogic:pool:poolname");
    The problem is as follows:
    Every time we modify a stored procedure (DROP ... CREATE ...) our appfails when
    trying to use that stored procedure. We have to shut down the server andrestart
    it in order to keep going.
    The stack trace:
    java.sql.SQLException: SPL routine(disponibilidad_hot) is no longer valid.

  • Servlet JDBC

    Can anyone please help me with pointing to the right direction on webapplications.
    I have a table in the database that returns 50K rows when running a query. I have been reading through some books and forums, SDN including that a correct way to access the database is through the Business tier EJB session beans and JPA and access these objects from Servlets. I understand that and I have an example that works using paging so I do not need to send all 50K records at once. My question is, the resultset retrieves entity objects and I have to create data transfer objects for each one of them to send to the GWT client? Doesn't it mean I have twice as much objects in the memory at a time to compare with accessing database through JDBC from Servlets directly? In the later case I wouldn't have any entity objects and occupy less memory? Is it completely wrong idea?
    Thanks

    Never mind,
    Thanks for answer.I don't understand what the problem is here.
    Dod you have a problem with making them Serializable? They have to be Serializable if you want to make them arguments to remote methods anyway.
