PleaseHelp on jsp and Mysql connectivity and a lot of exception errors

Hi,
I am Trying to connect a JSP page with Mysql database. I am having a lot of probelms. After having a lot of problems in connecting the JSp with Mysql. Intilally it was giving me the exception error that " NO appropriate driver was found. After modifying the URl it was fine. Now It is giving the Following errors.
servlet.ServletException: Communication link failure: java.io.IOException, underlying cause: Unexpected end of input stream ** BEGIN NESTED EXCEPTION ** java.io.IOException MESSAGE: Unexpected end of input stream
In a window before loading the Explorer page it is giving the following error that The port 8081 is already in use and i should expand to other ports. Noraml JSP Files which used to work before are also not working .
Internal Tomcat JWSDP is alos not working. If i try to start the server it says that port 8081 is already in USe . A java.net.connection exception is also occuring. The normal JSP files are also not working. What is Happening. I am also giving the code i have writted. PLease tellme why so many exception errors are occuring.
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:8081/mis_project", "root", " ");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("Select study_semester FROM Semester");
while(rs.next()) {
%>
<option value="<%= rs.getString("Study_Semester") %>">
</option>
<% }
if(rs!=null) rs.close();
if(stmt!=null) stmt.close();
if(con!=null) con.close();
I am trying to connect to Mysql and automatocally populate a field in a Form in later JSp pages i intend to record the data entered in these fields into other tables.

<%
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/myDB?user=username&password=mypass");
Statement stmt = conn.createStatement(java.sql.ResultSet.TYPE_FORWARD_ONLY, java.sql.ResultSet.CONCUR_READ_ONLY);
String cat = "";
          try{
          cat = request.getParameter("category");
          }catch(NullPointerException npe){}
          ResultSet rs = stmt.executeQuery("SELECT id,fullname FROM users WHERE category LIKE '%motor%' AND subcategory like '%"+cat+"%'");
     %>
This piece gets a category parameter from a form post and uses it to search for a specific category in a database table. I think maybe u need to download JConnector from mysql site and unzip it to the classes folder of your WEB-INF in Tomcat server...... i hope this helps a bit

Unable to connect JSP and MySQL

Hi, I am new to this forum
I've started developing web pages using JSP
I've the problem connecting JSP and MySQL database. I've created the page that retrive records from mysql table. But the connection fail to access to database it gives me this error:
org.apache.jasper.JasperException: Exception in JSP: /retreive_book.jsp:15
The code is:
12: <%
13: //Class.forName("com.mysql.jdbc.Driver").newInstance();
14: Class.forName("org.gjt.mm.mysql.Driver");
15: connection = DriverManager.getConnection(connectionURL,"","");
16: statement = connection.createStatement();
17: rs = statement.executeQuery("SELECT * FROM books_detail");
18: %>
And the connectionURL parameter has this value:
String connectionURL = "jdbc:mysql://localhost:3306/books?username=;password=";
root cause msg is:
java.sql.SQLException: Invalid authorization specification: Access denied for user 'nobody'@'localhost' (using password: NO)
Please can anyone help me. It is 3 days now trying to do that but not succeded yet

Hi
Yes It is true that my MySQl installation its username is root. So how should put that in the url. Cause I did that but it didn.t work
String connectionURL= "jdbc:mysql://localhost:3306/books?username=root;password=";
If I write in that manner is it correct for root username or should I put a single quote
Thanks

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?

Subject: PHP and MySQL Connection problem
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.

Weblogic8.1 and mysql connection failure, please help

Pardon me for repeating this topic. I have spent 2 days on this but still ended
up with failure.
The similar configuration works very well under wls7.0.
It should not be a problem of jdbc driver or its classpath setting, since the
system console say "successful..."
But when I try to access jsp and servlets, it always throws execeptions. All projects
run successfully under wls7.0 don't work.
Please give me some advice, thanks in advance.
The following is my connection pool setting found in config.xml:
<JDBCConnectionPool DriverName="com.mysql.jdbc.Driver"
Name="MySQLConnectionPool" Password="{3DES}aMsyd4ZSbSg="
Properties="user=root" Targets="cgServer" URL="jdbc:mysql://localhost/userdb"/>
<JDBCTxDataSource EnableTwoPhaseCommit="true"
JNDIName="MySQLDataSource" Name="MySQLDataSource"
PoolName="MySQLConnectionPool" Targets="cgServer"/>
The screen shot of the exceptions is as below:

1. This assumes that you have downloaded the mysql database and configured it and started
it by running mysqld. In my case, I installed it in d:/mysql.
2. It also assumes that you have configured a user on the database.
I configured a user "test" with password "test" on the database "mysql" on "localhost" using
mysql --user=root mysql
grant all privileges on *.* to test@localhost identified by 'test' with grant option;
3. It assumes that you have downloaded the Connector/J zip file and pulled out the jar file.
In my case, I renamed it and copied it to d:/mysql/lib/jdbc.jar.
4. It is absolutely necessary that you put the jar file in your server classpath. It won't
work without doing that. Then I booted the server.
5. I used the WLS 8.1 console to configure the connection pool and associated data source.
In my case, they look like the following:
<JDBCConnectionPool DriverName="org.gjt.mm.mysql.Driver"
Name="mysql" Password="test"
Properties="user=test"
Targets="myserver"
TestTableName="SQL SELECT 1"
URL="jdbc:mysql://localhost:3306/mysql"/>
<JDBCTxDataSource
JNDIName="myDataSource"
Name="myDataSource"
PoolName="mysql"
Targets="myserver"/>
Note that the console uses the old class name for the driver. There is a new class name but
the old name still exists and we figured it would cover folks using the old and new classes.
6. I'll attach a client program that looks up the datasource associated with the connection pool,
gets a connection, and does some stuff with the connection.
The user/password combination must have security priviledges in WLS to reserve a connection
on the pool.
The code for this program is taken almost entirely from the WLS JDBC documentation.
This is all pretty standard stuff.

Problems with JSP and MySql bean.

Hi,
I'm new to JSP and I'm having some problems with it. I'm trying to do a simple login where a java class (bean?) handles the SQL injektion. I have deployed the page on tomcat and it works fine, except that the sqlinjektion does basically nothing. I have installed the mysql driver. I think there is something wrong with the java class, or the way im calling it. It does not produce any error. But its like it would never actually process the java code, because ive tried to append things to error string to see what is going on, nothing happens. everything stay null, no exceptions are thrown. If I implement the code to JSP itself, it does load the driver and print exception that there is no connection to database (which is correct). What am I missing? Code follows:
the sqlhandler:
public abstract class SqlInjektor {
     private static String Database = "*****";
     private static String serverName = "localhost:3306";
     private static String usrName="******";
     private static String passw="******";
     * @return Connection
     public static Connection createConnection(String error){
          Connection mySqlCon = null;
          try{
               Class.forName("com.mysql.jdbc.Driver").newInstance();
          catch(Exception E){
               PrintWriter out = response.getWriter();
               out.println("lol");
          String url = "jdbc:mysql://" + serverName + "/" + Database + "?user=" + usrName + "&password=" + passw;
          try{
               mySqlCon = DriverManager.getConnection(url);
          catch (Exception E){
               E.printStackTrace(System.out);
          return mySqlCon;
     * Metodi saa sy�tteen��n SQL komennon, jonka se suorittaa sek� palauttaa komennon tulokset.
     * @param command
     * @return ResultSet
     public static ResultSet querySQL(String command,String error, Connection con){
          ResultSet rs = null;
          try{
               Statement stmt = con.createStatement();
               rs = stmt.executeQuery(command);
          catch(Exception E){
               E.printStackTrace(System.out);
          return rs;

Hi,
I'm new to JSP and I'm having some problems with it. I'm trying to do a simple login where a java class (bean?) handles the SQL injektion. I have deployed the page on tomcat and it works fine, except that the sqlinjektion does basically nothing. I have installed the mysql driver. I think there is something wrong with the java class, or the way im calling it. It does not produce any error. But its like it would never actually process the java code, because ive tried to append things to error string to see what is going on, nothing happens. everything stay null, no exceptions are thrown. If I implement the code to JSP itself, it does load the driver and print exception that there is no connection to database (which is correct). What am I missing? Code follows:
the sqlhandler:
public abstract class SqlInjektor {
     private static String Database = "*****";
     private static String serverName = "localhost:3306";
     private static String usrName="******";
     private static String passw="******";
     * @return Connection
     public static Connection createConnection(String error){
          Connection mySqlCon = null;
          try{
               Class.forName("com.mysql.jdbc.Driver").newInstance();
          catch(Exception E){
               PrintWriter out = response.getWriter();
               out.println("lol");
          String url = "jdbc:mysql://" + serverName + "/" + Database + "?user=" + usrName + "&password=" + passw;
          try{
               mySqlCon = DriverManager.getConnection(url);
          catch (Exception E){
               E.printStackTrace(System.out);
          return mySqlCon;
     * Metodi saa sy�tteen��n SQL komennon, jonka se suorittaa sek� palauttaa komennon tulokset.
     * @param command
     * @return ResultSet
     public static ResultSet querySQL(String command,String error, Connection con){
          ResultSet rs = null;
          try{
               Statement stmt = con.createStatement();
               rs = stmt.executeQuery(command);
          catch(Exception E){
               E.printStackTrace(System.out);
          return rs;

Syntac error in JSP and MySQL

HI guys,
I have been facing another problem. The codings below. Worked well with my JSP and Access database.
Then I transfered my database to MySQL and it gives out syntax error in my SQL statement.
CODE1:
     sql = "SELECT Week, SUM (Total_Inspected) AS ins, SUM (Total_Rejected) AS rej, SUM (Total_Accepted) AS acc, SUM (DPPM) AS dpp, SUM (Yield) AS yeel FROM Calc_Data WHERE MONTH(Inspect_Date) ="+bulann+" GROUP BY Week";
     ResultSet rs = stm.executeQuery(sql);
CODE2:
String query   = "SELECT ID, Model, Lot_No, Lot_Qty, Inspected_By, Reject_Desc, Area_Concerned, Location, Remark FROM OQA WHERE Customer = '"+customer+"' AND Inspect_Date =#"+tarikh+"#";
ResultSet rs   = stmt.executeQuery(query);

Whenever you have this type of problem, the easiest
solution is to take the sql and try running it
directly. For MySQL, you can either use the
command-line client, or there are a few graphical
clients that can handle it. Just type in the query,
run it, and let the database itself tell you what the
error is.
In any case, you probably won't find much useful
advice on a JSP forum, esp. since the problem has
absolutely nothing to do with JSP.Indeed - I agree with this. - MOD

Few question about Java and MySQL connection

Hi!
I have some problems with creating connection between Java and MySQL.
I followed the restrictions in mysql-connector-java.jar' readme, I set the CLASSPATH :
CLASSPATH=.;D:/mysql/mysql-connector-java.jar;
I copied this jar file to the right place (descripted above), and I used the right steps to load it:
Class.forName('com.mysql.jdbc.Driver"); and it throws a ClassNotFoundException
Why? All the paths are correct, everything is on the right place.... I dont know why.
When I installed the JBuilder8, and copied the jar file to JBuilder8/jdk4/jre/lib/ext it worked without any CLASSPATH in enviromental variables.
If I want to run my program on machines where are not JBuilder, what should I do?
Please help, if you can.
Thanks,
henpanta

Yeah. So if I compiled my program with JBuilder to an .exe file, I cant run it on other machines, if the jar file isnt in the same place?
If I tried your advice, java -classpath mymainclass I got the next message:
main class not found. Believe me, its there. :(

JSP and DB2 Connection

CS6, FTP and MySQL Connection ERRORs

Adobe CS6 Dreamweaver
I have the latest + updates of CS6 for Mac OS X 10.7.4.latest
I can FTP, but files are not readable after the upload, on any web hosting provider.
I have to use a thrid party FTP application (CyberDuck or Trnsmit) to make this happen.
NOT HAPPY about this £2500 CS6 Master Collection spend not working !!!!
When I try to connect via MySQL I get this error and failed actions:

I have checked the folders & content for ...
_mmServerScripts
Connections
are uploaded properly (having to use a third party FTP application, see above).
I have the correct logins details for FTP and MySQL, as other MySQL Apps (Sequel Pro) have no problem connecting to any web hosting proivdier for MySQL using the exact same login details.
This is the same on my iMac or my MacBook Pro.

Hello David, I am having this issue getting errors while trying to get my SQL to connect with the server. I clicked on the link you provided and I get a "you do not have permission to view this" message. Can you please share what ever solution that adobe has with me too.
I am really really irritated with this issue, as someone else stated this is really inconvenient when I want to get some work done. I am also upset that I bought this software, especially if I cant find a solution.

?An error occurred at line: 20 in the jsp file: /singleupload/BookEntryForm.jsp stmt cannot be resolved
That means it can't see any variable declared called "stmt"
There isn't one at this point.
The stmt variable you have declared up above, is nested in curly braces - within your try/catch statement. As such it only has scope within those curly braces. If you want to use stmt outside of the try block, you need to declare stmt outside of it.
And yes, I echo Balusc's comments about scriptlet code in a jsp page.
A better solution would be to write a java class with a method that does the database query, and returns a List of objects.
Your JSP can then take that list of objects and display them on the page.
Its a bit more work, but makes the code much easier to write/maintain/test because you separate out the "data" and "view" layers.

JDBC and MySQL connectivity problem

The code i hav attached generates Connectivity exception.. the prob is with the part in bold.. can anyone help
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class testconn {
public static void main(String args[]) {
    Connection con = null;
            String serverName = "localhost:8080";
        String mydatabase = "imagedb";
        String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url
        String username = "am";
        String password = "ta";
    try {
      Class.forName("com.mysql.jdbc.Driver");
     con= DriverManager.getConnection(url, username, password);
      if(!con.isClosed())
        System.out.println("Successfully connected to " +
          "MySQL server using TCP/IP...");
    } catch(Exception e) {
      System.err.println("Exception: " + e);
    } finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
}

I had such issue too, and I fixed it by adding in the environment variables the CLASSPATH entry that pointed to all the directories containing the .jar needed for the applications.
for example I used jodbc folder to connect mysql database (I installed last version and I got same issue than yours and it seems to be a 'connector' issue, exactly the same issue than yours) I got something like
CLASSPATH=my root dir/the java dir/the lib dir/jodbc;my root dir/the java dir/other important libs containing .jar files;
This is what I got for the issue, still working around (at the level of mysql all is ok, ...)

Maybe the drivers used (last one: connector/j 3.1.12). The .jar file is in the %classpath% directory c:\Program Files\Java\jdk1.5.0_06\lib.
Can't really understand why this code won't run anymore, ...
I took a look on the other computer where the same code is running ok.
These are the differences:
mysql server is 5.0.18 on the other computer the version is 3.23.41
mysql connector is 3.51.12 on the other computer the version is 3.0.10
access rights are the same because the database is the dumped one from 3.23.41 to 5.0.18, and I'm quite good with the dbms management (I'm IT developper in fact, trying to take over java technology ;) )
in this case this is not a sql error but java error.
the jar file is set to the %classpath% folder on both computers
I copied the jar from the other computer, removing the new .jar file and... it failed, exactly the same issue
Still working around, ...

JSP and MySQL

dear all,
I am new to sql and database programming and am a bit confussed about the line:
Connection Conn = DriverManager.getConnection("jdbc:mysql:dbname");
the jdbc is the what is the dbname??? is it the address of the database on your hard drive??? how is it formated??? what is the file that you need to point to??? how dies this work
Thanks T

Hi
the JDBC Url should have the following format
jdbc:mysql://<hostname>:<port>/<database>
If your MySQL Database is running at your local host
and it is using the default port than you can use
jdbc:mysql://127.0.0.1:3306/test
jdbc -> Means you are trying to open a jdbc connection
mysql -> MySQL Databse Driver
(make sure that your MySQL jdbc driver is registered)
to connect to the test database on your MySQL Server

Jsp and database connection using bean

* I want create a bean to handle database connectivity.The
          <jsp:usebean> tag uses
          no argument constructor ..so I cannot pass the userid and password to
          the constructor.
          So how can I create a database connection when the user_id and password
          will be a part of parameter ?
          * Now I'm opening database connection in the jsp scriplets. Everytime I
          refresh the
          jsp page a new connection is created ? Is it not going to choke the
          database ? I cannot use connection pool because every user logs in with
          different userid.
          Thanks


You can pass your arguments in this way:
          <jsp:usebean id="myBean" scope="page"/>
          <jsp:setProperty name="myBean" property="userId", value=<%= user_id%>/>
          <jsp:setProperty name="myBean" property="password", value=<%=
          user_password%>/>
          of course, in your bean class, you should create two setter methods,
          setUserId and setPassword.
          Hopefully, this will help you.
