Connecting database to Servlets

Hi i am trying to connect MySql to a simple servlet program. The MySql server gets started and the tables and data are retrievable, and the servlet is compiled, but unable to run the servlet in the browser. I get a blank page when i run the program in the browser.
I have set all the classpaths right, and have mapped the class file in the web.xml. This is my servlet program:
import java.io.*;
import java.lang.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
public class servsql extends HttpServlet
 public void doGet(HttpServletRequest req, HttpServletResponse res) throw
s ServletException,IOException
 Connection con=null;
 Statement stat=null;
 ResultSet rs=null;
 String username="root";
 String password="tellno11";
 String url="jdbc:mysql://127.0.0.1/goldendb";
 try{
 Class.forName("com.mysql.jdbc.Driver").newInstance();
 con=DriverManager.getConnection(url,username,password);
 stat=con.createStatement();
 rs=stat.executeQuery("select * from emp");
 res.setContentType("text/html");
 PrintWriter out= res.getWriter();
 while (rs.next())
 out.println("<html>");
 out.println("<head><title>First SQL Program</title></head>");
 out.println("<body>rs.getString(1)</body>");
 out.println("</html>");
 } catch(Exception e) { }
}Any suggestions of how to fix the problem?
Thanks,

Connecting database in Servlet vs App

Hi,
Windows 2000 Server / SQL Server 2000 / Tomcat
I have a class managing the connections and requests to databases.
When invoking it from a java app context (launched from the command line java myApp), it's working fine
but when the same connection is made from a servlet, the Class.forName(dbDriver) doesn't work. I don't have a specific messsage, the Exception e.getMessage() returns only the driver used to access the database.
Have any idea ?

here is the test I made, creating a servlet as simple as possible :
public void doGet(HttpServletRequest requete, HttpServletResponse response) throws IOException, ServletException{
test( response );
public void test(HttpServletResponse response){
boolean correct = true;
PrintWriter pw = null;
try{
response.setContentType( "text/html" );
pw = response.getWriter();
catch(Exception e){ correct = false;}
if ( correct ){
try{
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" ).newInstance();
catch( Exception e ){
pw.println( "Error : " + e.getMessage() );
the Class.forName send me in the Exception.
The message is Error : com.microsoft.jdbc.sqlserver.SQLServerDriver
I'm running Windows 2000 Server, SQL Server 2000, Microsoft SQL Server 2000 Driver for JDBC, Tomcat 5.5, JRE 1.5.0
The same Class.forName is ok when called from the main of a java App.

Connecting database in servlet

I am trying to connect to the database in a servlet but it throws a ClassNotFoundException.
the problem is when i am trying with the same piece of code in a simple java class. it works perfectly fine.
Server i am using is - Jakarta-Tomcat 5.
driver - com.microsoft.sqlserverdriver.SQLServerDriver.
all the packages imported are also the same..
Can any one suggest a solution to this...

Did you put the sqlsever jdbc jars in WEB-INF/lib, or is it on Tomcat's classpath?

Cannot connect to database with servlet thru apache http server / vhosts

Hello,
I have an application that works perfectly when Tomcat 5.5 is running stand-alone, but when I run Tomcat and Apache HTTP Server together, I get an error when trying to connect to the database. Servlets are working fine otherwise. Connection pooling is setup and working fine for Tomcat stand-alone. With the Apache server, I'm running Virtual Hosts.
My guess is that I need something in the host block of server.xml about the context.xml where the db resource pool is defined. This is what I have so far in server.xml:
<Host name="www.mydomain.com" debug="0" appBase="d:/WebApps/mydomain"
unpackWARs="true" autoDeploy="true">
<Context path="" docBase="" debug="0"/>
</Host>
Or the problem may be caused by something else entirely. Does anybody have any suggestions? Your help is greatly appreciated.
Thank you,
Logan

A little help? Anybody?
I can connect to the database with Tomcat stand-alone, but not with Tomcat integrated with Apache. I have seen this problem described elsewhere, but no solution has been found.

HELP IN DATABASE CONNECTIVITY IN A SERVLET`

HI there,
I have some issues in an application. I have a servlet which is called Servlet1.class. I have deployed this in my tomcat webapps folder. There is a stand alone application called MailAgent.class which pools into a mail box and retrieves the messages and converts them as HTTP messages. Then the MailAgent.class sends the HTTP message as multipart post (email message) to the servlet. In the servlet I am trying to establish a database connection with the JDBC driver from third party vendor. I am unable to get the driver class when I establish the connection with the database. Is there any issues with servlet and database access. I am able to connect if I run as a stand alone application.
Any help would be greatly appreciated.
Thanks
John

There shouldn't be any .class file in your webapps folder. I hope you mean that you created a subdirectory under webapps, with a WEB-INF under that and /classes and /lib under that. Your servlet .class file and its package directory structure belong under webapps/yourApp/WEB-INF/classes, right?
You can create database connections in a servlet, although I agree with the previous poster that you'd be better off putting database code into objects that you could test off-line, without the servlet.
You've got to have the JDBC driver JARs in the webapps/yourApp/WEB-INF/lib directory, for starters.
If you get really adventurous you can create a pooled JNDI data source, but maybe that's another day's work. Get the basic connection working first.

Connecting to MySQL Database with Servlet

Hi All,
I want to connect to MySQL Database from servlet.
I am using Tomcat websever 3.3.1, where i have to set classpath of mysql jdbc driver.
I tried by copying mysql jdbc driver in so many directiories of Tomcat server but it is
giving me error like "no specified driver find"
So please send me all the solutions and how to set the classpath to connect to
mysql database.
Thanks

U r correct that so many people are giving me solutions but that are not working for me
I think i not correct in setting the classapath to mysql jdbc driver.
1)I have unjarred correctly and all the classes are present in that.
yes driver class is there in that .
2)Now i am using new version of the mysqljdbc that is 2.0.13

Connection to the Database thru Servlet

Hello:
I have just read some threads in this forum and noticed that people saying that connecting to the database in JSP is not a good Java Programming Habit. So, could you please give a little guidance on connection to the Oracle database in servlet. Thank you very much.
Oscar.

You use standard JDBC:
http://java.sun.com/docs/books/tutorial/jdbc/index.htmlIn a servlet container, most of the time, you set up a connection pool that you access through JNDI
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.htmlFor larger applications you might want to use "Data Access Objects"

Failed to open the connection - database vendor code 17

I'm upgrading a VB.net Windows Forms application from 1.1 to 4.0. In the reporting form, the list of reports you can choose are pulled from a folder where the .rpt files reside. Once the user chooses a report and executes it, vb code populates the current database connection information and displays the report in the report viewer control.
The following things are true:
- Version 1.1 works on my systems and my customers systems
- The code has not been changed, except that it now targets .Net 4.0 instead of 1.1
- The exact same .rpt files are being used
- Version 4.0 connects to the same database my customer is using, and I can run the reports just fine from here.
- Version 4.0 is able to connect to the database just fine from my customers systems (using the same connection information provided to the report)
- My customer installed this: http://downloads.businessobjects.com/akdlm/cr4vs2010/CRforVS_redist_install_32bit_13_0_2.zip
The only problem is that my customer encounters this error when trying to run any report from his systems:
Failed to open the connection.
Details: Database Vendor Code: 17
Failed to open the connection.
Orders.BOL.TaskDetail {393C9017-0ED1-4E1E-8824-E222F4B9D14C}.rpt
Details: Database Vendor Code: 17
I read all of the articles I could find, and they either don't describe this exact situation, or there is insufficient information for troubleshooting this issue. Are there steps that I've missed to make Crystal Reports for VS2010 work on my customer's systems?
Your help is appreciated,
Mark

Hi Mark,
More information required -
- Does this happen with all reports or few?
- What is the connection type used for the report to connect to the database (OLEDB,ODBC etc)
- Are you changing the database at runtime?
few things you could check
- Check if the database is accaessible from the client machine with proper permissions / rights.
- If its an ODBC connection check if the DSN with same name is created on the client machine.
- Check the driver / provided used by the report to connect to the DB, verify that the same is installed on the client machine. (SQL NAtive client, SQL Server etc)
Also take a look at below articles discussing the simillar issue.
[CR for VS2010: Failed to Open Connection [Database Vendor Code: 17 ]|CR for VS2010: Failed to Open Connection [Database Vendor Code: 17 ]]

Retrieve multiple images from database to servlet

When I retrieve, I got 3 rows of binary data, but I don't know how to display it on the Servlet/JSP pages.I will pick this bit of your post, because you seemed to have several partly-overlapping questions.
You are going about this wrong. You need to decide what your HTML will look like before you start writing servlet code. In this case you want to have something like a table, with an image in each row, right? Now what does the HTML for that look like? It's a <table> element, and so on, but what about the images? Well this is HTML, so it can't contain the binary images. It has to contains links to the images, and the browser will download the image from each of those links and put all of the downloads together into the page it displays.
That means you can't do it all with one servlet. You need a main servlet that generates the HTML, with the <table> element and the links to the images. Probably you need some DB calls here to find out how many images you're going to have, but you don't need to get them in this servlet. You just need to generate a link for each of them.
Then you need a second servlet that gets an image. It's going to get a single row from the DB and return the binary image you read from that row. Make sure to use "image/jpg" or whatever's appropriate instead of "text/html" in your response's content type here.
I will leave you to carry on from here. First step is to design the HTML that your main servlet will produce; remember that the links it generates need to carry enough information for the second servlet to be able to find the right image in the DB.

Databases and servlets

I'm writing an application that displays all the records in a database using servlets, everything works as it should when run under Tomcat 3.2.3. I've since installed the Win32 version of Apache and the JServ plugin. This works fine except when asked to run the servlet that accesses a database. The servlet loads OK but an exception is thrown when accessing the records (See below). Does anybody have any ideas why this is? Thanks.
Exception thrown:
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

If you're using the jdbc-odbc bridge that ships with the Java api's, then you need to create the Driver and the Connection.
You need lines that look something like:
Driver driver = (Driver) Class.forName(driverName).newInstance();
Connection con = DriverManager.getConnection( dataSourceURL, UserName, Password);

How to delete a record in a connected database?

We are encountering a problem using the delete function for removing a record in a connected database table. The database is an excel-file and we are able to add a new record, update existing records but not delete records. We are using the following script in FormCalc since I read that the function does not work in JavaScript:
$sourceSet.DataConnection.delete()
The error message returned is:
"Deleting data in a linked table is not supported by this ISAM."
We are also curious to know how we can reload the connection so that for example a drop-down list containing values from each record in the table is updated automatically when we insert a new record.
Thanks!
Annika

You also asked: We are also curious to know how we can reload the connection so that for example a drop-down list containing values from each record in the table is updated automatically when we insert a new record. You should be able to achieve this quite easily using the Data Drop Down List from the Library palette's Custom tab. This object has a pre-defined Initialize script which populates the list with items from a data connection you specify. While the object is pre-configured to load items from the data connection only upon initialization (which only occurs when the form is loaded and after a data merge), you could move the script into a Script Object function and call it whenever you insert a new record (just after the statement which inserts the record). This is the script from the Initialize event of the Data Drop Down list put into a Script Object function called LoadDropDownList which takes the drop down list to populate using the data connection as a parameter: <pre>function LoadDropDownList(oDropDownList) { /* This dropdown list object will populate two columns with data from a data connection. sDataConnectionName - name of the data connection to get the data from. Note the data connection will appear in the Data View. sColHiddenValue - this is the hidden value column of the dropdown. Specify the table column name used for populating. sColDisplayText - this is the display text column of the dropdown. Specify the table column name used for populating. These variables must be assigned for this script to run correctly. Replace <value> with the correct value. */ var sDataConnectionName = "<value>"; // example - var sDataConnectionName = "MyDataConnection"; var sColHiddenValue = "<value>"; // example - var sColHiddenValue = "MyIndexValue"; var sColDisplayText = "<value>"; // example - var sColDisplayText = "MyDescription" // Search for sourceSet node which matchs the DataConnection name var nIndex = 0; while(xfa.sourceSet.nodes.item(nIndex).name != sDataConnectionName) { nIndex++; } var oDB = xfa.sourceSet.nodes.item(nIndex); oDB.open(); oDB.first(); // Search node with the class name "command" var nDBIndex = 0; while(oDB.nodes.item(nDBIndex).className != "command") { nDBIndex++; } // Backup the original settings before assigning BOF and EOF to stay var sBOFBackup = oDB.nodes.item(nDBIndex).query.recordSet.getAttribute("bofAction"); var sEOFBackup = oDB.nodes.item(nDBIndex).query.recordSet.getAttribute("eofAction"); oDB.nodes.item(nDBIndex).query.recordSet.setAttribute("stayBOF", "bofAction"); oDB.nodes.item(nDBIndex).query.recordSet.setAttribute("stayEOF", "eofAction"); // Clear the list first so that we replace any existing items oDropDownList.clearItems(); // Search for the record node with the matching Data Connection name nIndex = 0; while(xfa.record.nodes.item(nIndex).name != sDataConnectionName) { nIndex++; } var oRecord = xfa.record.nodes.item(nIndex); // Find the value node var oValueNode = null; var oTextNode = null; for(var nColIndex = 0; nColIndex < oRecord.nodes.length; nColIndex++) { if(oRecord.nodes.item(nColIndex).name == sColHiddenValue) { oValueNode = oRecord.nodes.item(nColIndex); } else if(oRecord.nodes.item(nColIndex).name == sColDisplayText) { oTextNode = oRecord.nodes.item(nColIndex); } } while(!oDB.isEOF()) { oDropDownList.addItem(oTextNode.value, oValueNode.value); oDB.next(); } // Restore the original settings oDB.nodes.item(nDBIndex).query.recordSet.setAttribute(sBOFBackup, "bofAction"); oDB.nodes.item(nDBIndex).query.recordSet.setAttribute(sEOFBackup, "eofAction"); // Close connection oDB.close(); }</pre> The required modifications to the original script are in bold. The easiest way to create the Script Object is to right-click on the top-level form object ("form1" by default) in the Hierarchy palette and select the Insert Script Object option. This will insert an un-named Script Object which you should then rename to something meaningful like, "ScriptObject". Once you've done this, you can call the function from any event on any object on your form with the following JavaScript: <pre>ScriptObject.LoadDropDownList(<SOM expression for drop down list>);</pre> If you were calling this function on an "add record" button's Click event, the drop down list was named "DropDown" and both objects were in the same subform, you would do this: <pre>ScriptObject.LoadDropDownList(DropDown);</pre> Stefan Adobe Systems

Urgent: how to run applet which connected to the servlet?

hi frends:
i have written an applet on the server side and it supposed to pass parameters to my servlet and retrieve some info from the servlet.
i put both applet and servlet under tomcat../WEB-INF/classes. but when i run the applet from the web browser, there is no response from the servlet.
could anyone help me to solve this problem?
one more thing is i know that applet is able to connect to servlet, but how about java application? is it able to do so? if yes, is it also using URLconnection as applet? and how to run it?
i will be very appreciate if anyone can help me... thanx a million.

You can connect to the servlet from an application.There's a URL class in java.net that has an openConnection method. Then cast the return to an HttpURLConnection and use setMethod to set up as a post request.This may be the default if you call setDoOutput(true) on the URLConnection. Then you'll need to get an OutputStream and write properly formatted form POST data to it. It's also possible to encode your data on the URL, even when using the POST method, and this may be easier when doing it programmatically from an application. To send a get request you can append the name-value pair at the end of the url.

ExtendScript has a Socket object prototype you can use to e.g. connect to the internet. Calling a web service would probably be more elegant than addressing the database directly. Socket is fairly low-level, though. If you need something easier, you could always try out http://extendables.org/docs/packages/http/doc/readme.html
I seem to recall some InDesign plug-ins you could buy that allow you to connect to a database directly, but you'd have to google that yourself.
