SQL from JSP

Hi everybody,
i started to program in JSP only from yesterday and i'd like to execute a statement SQL from my JSP page....
My code is
<%Class.forName("oracle.jdbc.driver.OracleDriver");%>
<%java.sql.Connection c = java.sql.DriverManager.getConnection("ora817", "protocs", "protocs");%>
<% try {
Statement dbst = c.createStatement();
ResultSet rs;
rs = dbst.executeQuery("update upload_status set stato= 4;");
c.close ();
catch (SQLException e) {
out.println("Non riesco a fare l'update "+e);
return;
%>
So when i use use JDeveloper and i run the project i obtain the following error
500 Internal Server Error
java.sql.SQLException: No suitable driver

I hope that some one can help me

Let's see.
You don't have the Oracle JDBC driver JAR in the CLASSPATH. Put it in WEB-INF/lib in your Web app's WAR file.
Your Oracle database URL is totally wrong. It should look something like this:
jdbc:oracle:thin:@host:1521:database
You should separate out that JDBC code and test it in a separate object on the command line before you try sticking it into a JSP. At least make sure that you know how to connect to the database.
Sounds like you need these:

Is it possible to call the SQL Server DB from jsp to java?

im doing a configurable system where you can create your own table using the system. i can do the creation of table by running the statement CREATE TABLE...........(with attributes) in java.
Let's say i have created tblST1 with attributes st_ID, st_Name, st_Description.
My problem is i dont know if it's possible to retrieve all the attributes from jsp to java.

jverd: i need your help. Iv read all the links u posted but im having a hard time in understanding them.
For the site http://java.sun.com/j2se/1.4.2/docs/api/java/sql/ResultSetMetaData.html , there's a code there which is...
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);
what i did was, i inserted it in my java code which is :
public boolean checkFieldTable2()
          boolean checked = false;
          try
               IRMS_DBConnect db = new IRMS_DBConnect();
               db.openCon();
               ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
          ResultSetMetaData rsmd = rs.getMetaData();
          int numberOfColumns = rsmd.getColumnCount();
          boolean b = rsmd.isSearchable(1);
               db.closeCon();
               checked = true;
          catch (Exception ex)
               System.out.println("Error on Execution: " + ex);
          return checked;
and i compiled it and there was an error that the variable stmt was not initialized. Am i doing the right way?

The syntax for accessing MS SQL db from JSP

One way of doing this is to use ODBC. Here's an example:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:<odbc name>", "<login>", "<password>");

i would like to make a big data load from web interface, using SQL Loader or similar, because this utility allows a great performance.
I think that i can make a JSP or Servlet to open file, and create insert statement into a loop, but the performance is very bad for 30000 inpuits.
Help me please

Insert date time into oracle database from jsp

pls tell me ,from jsp how can I insert datetime values into oracle database .I am using oracle 9i .here is codethat i have tried
html--code
<select name="date">
<option selected>dd</option>
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
</select>
<select name="month">

<option>2004</option>
<option>2005</option>
<option>2006</option>
<option>2007</option>
</select>
here the jsp code
<% date= request.getParameter("date"); %>
<% month= request.getParameter("month"); %>
<% year= request.getParameter("year"); %>
try
{ Class.forName("oracle.jdbc.driver.OracleDriver"); }
catch (ClassNotFoundException exception)
try
     Connection connection = null;
     out.println("connectiong the database");
connection = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:orcsid","scott","tiger");
out.println("connection getted");
     int rows = 0;
     String query_2 = "insert into mrdetails values(?)";
     String dob = date+month+year;
     prepstat = connection.prepareStatement(query_2);
     prepstat.setTimestamp(4,dob);
     rows = prepstat.executeUpdate();
     out.println("data updated");
catch (Exception exception3)
out.println("Exception raised"+exception3.toString());
}

To insert date values into a database, you should use java.sql.Date. If it also has a time component, then java.sql.TimeStamp.
Your use of prepared statements is good.
You just need to convert the parameters into a date.
One way to do this is using java.text.SimpleDateFormat.
int rows = 0;
String query_2 = "insert into mrdetails values(?)";
String dob = date+"/" + month+ "/" + year;
SimpleDateFormat sdf = new SImpleDateFormat("dd/MM/yyyy");
java.util.Date javaDate = sdf.parse(dob);
java.sql.Date sqlDate = new java.sql.Date(javaDate .getTime);
prepstat = connection.prepareStatement(query_2);
prepstat.setTimestamp(4,sqlDate);
rows = prepstat.executeUpdate();
out.println("data updated");Cheers,

I would like to know that how can I do for autocommit from jsp. For example, the looping is 10 times which mean I will add 10 records to the db. If the last record is failed to add to db, "how can I rollback the perivious records?" or guide me to set the commit function to handle that case. Thanks a lot for take your time to read my question.

Hello.
The best method is using a session bean and container managed transactions. Other method is using sessions bean and the user transaction object (JTA-JTS).
so, JDBC has transaction management too.
good luck.

HSQLDB Queries fail only from JSP

I am new to Servlets and JSP and have encountered a weird problem when trying to query HSQLDB from JSP pages. If I write a small servlet and deploy it from the same web application with the same classpath, the connection succeeds and queries return. If I make the connection from JSP under either Tomcat or Jetty I get a failure like:

Every previous question I have seen about this has been resolved by a classpath problem, but I have verified that the hsqldb.jar is getting loaded in my classpath, and the servlet works fine in the same webapp. Just not the JSP page. Any ideas? This is really frustrating. Thanks!
Karl

First of all let me say thanks for your help! I think at this point it's just a matter of getting to work because it should and I want to know what I am doing wrong. To test things out, I wrote a JSP in the same directory as the one which is failing. Instead of using the JSTL sql tags I just wrote a scriptlet inline which uses the java JDBC code directly. This should have the same classpath and access as the JSTL code, right? Anyway, it works fine. So maybe I am running into a bug in the JSTL of some kind? Here is the working code:
<%@ page import="java.sql.*" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql_rt" %>

Dear All,
Am working on a small struts project, i want to get values from JSP in the Action class, i tried with sending variables using request through URL, it works fine, any other way is there to send the values from JSP to action class. Am not having any input fields in the JSP.I have links.
Thanks,
vyrav.

I have a dispatch action for that am calling the action like this viewfiles.do?parameter=edit, and i have to send a variable ID from the same page, so am doing like this through java script, viewfiles.do?parameter=edit&id=10. Am able to get the id in the dispatch action edit, but when i start tomcat with security manager its not calling the action itself and its giving accesscontrol exception, but when i directly type viewfiles.do in URL its calling the action.
I dont know wats the problem, tomcat security manager not allowing this. Please help me.

Launching a Discoverer report from jsp page

Hi
I have a discoverer workbook created using BI Discoverer (for relational). I want to accept some parameters for this workbook from a jsp page, which will also have a "View report" button. This button when pressed should open up the Discoverer workbook and all the parameters from the jsp should be passed to the workbook.
Is it possible? If yes, any details on it?
We do the same thing successfully to launch Oracle Reports from jsps, we simply build the url in the jsp, and from jsp we submit it to a new window, and it opens up the report. Similar functionality we are looking to launch Discoverer reports.
Any help will be appreciated.
Thanks
Shalu

You can open the workbook with URL parameters with Discoverer Viewer much like you would Oracle Reports. Setting anything form the username, password, workbook name, worksheet, and parameters. All the information can be found in the following document:
http://download-east.oracle.com/docs/cd/B14099_11/bi.1012/b13918/urlstart.htm
The specific question your asking is addressed under 13.5.2 Example 2. Let me know if you have any issues

How to call RDF report from JSP page

Dear all,
I want to call a RDF report from JSP page. I am creating the JSP page using j developer 10G.
Can anyone help me out in this case. Is there any tag or procedure or any other way by of that i can perform this work.
please help and send the reply on [email protected],[email protected]
thanks

Hi Ashok,
You can use rwservlet - nothing really to do with JDeveloper. Once you have report server up and running (hint: read http://download-uk.oracle.com/docs/cd/B14099_19/bi.1012/b14048/toc.htm), you can call a report like this:
http://server:port/rwservlet?report=my_report.rdf&destype=cache&desformat=html&p_my_parameter=xxx etcHope this helps,
John
