Updating Data in Database using JSP

Hi all,
Can anyone please give me an idea that i have a JSP page that connects to the MS Access database. Now i have a query that shows all the data sorted by date for each individual user. Now if anyone wants to update from there meaning that there should be an update button.And if anyone press that then all the on the particular row will be shown in text boxes and then the user can modify the data. and press update to send the data to the database and show the correct one on that page again.
I know it is a bit hazy. Noe point is i created the query and the update button. Now how can i create text boxes for a particular row if button pressed and also i want to show the dataon this page again dont want to go to another page and do the same thing again. This will enable user to update each row separately on the same page and after all these he can log out. Please help me.
Another question how can i pass some data from an HTML form to the same JSP but in a different place meaning that if i direct the form to the same JSP like "form action=same.jsp" then it will start doing everything from the beginning of the page. But i want to go to a particular form of the same JSP page. Can anyone please help me.
I will be very grateful
Thanks.

Can anyone please look at it. Very Urgent. Thanks

Fetch Data from Database using JSP

Dear friends,
I am developing a portal for my College. The theme is to automate student details.
Here i have Screens for Posting, Editing , Viewing.
In Editing: I fetch the data from the backend using select query.
In the address field: I have value as "Big House".
The user keyed with double quotes when he keyed.
During extraction of the data i put the value inside a textbox as
<input type=text name=st1 value="<%=res.getString("street1")%>">
Here,
the value becomes as
<input type=text name=st1 value=""Big House "">
Here, you can notice that Big house i prefixed by double -double quotes.
The value should be Big House but the values is empty.
What i should. ???
Thanks in Advance.
Rengaraj.R

Try this:
<%
String addr = res.getString("street1");
//escape the double quotes from the address
addr = addr.replaceAll("[\"]",""");
%>
<input type="text" name="st1" value="<%=addr%>">

Efficient way of updating data to database table

what is the efficient way of updating data to database table .
i have huge amount of data in my internal table , how to use update statement in this case .
1. database table having 20 fields ,
2. one is key field and suppose 20 th field i want to change .
3. I have data for only 2 fields , i.e for ( 1 st and last 20 th field ) .
i can't use update statement in loop , as it is not good practice(hits database several times ) .
do it effects all the 20 fields for particular record .

Hi,
Use UPDATE statement , check below description from SAP help.
UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
Effect
Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab.
The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.

Question regarding Polling data from database using DB Adapters in BPEL

Hi,
I have the following question regarding Polling data from database using DB Adapters in BPEL -
If I am selecting data from multiple tables/view to ultimately generate hierarchical xml document, is there a way that I specify polling all of these tables/views. Is polling limited only to one table/view?
Thanks
Ravi

Hi Ravi,
your question seems to have been answered for the question of polling a set of tables with one as the root, and getting back a hierarchical xml representing multiple related tables.
However you can also poll for changes to both the root table and its related tables. Not sure if this was your question or the one already answered. If the former please check out the sample
bpel/samples/tutorials/122.DBAdapter/advanced/polling/PollingForChildUpdates

Error trying to run the Sample Code Virtual Private Database using JSP's

Hi.
I`ve downloaded the Virtual Private Database using JSP's example from the Oracle9iAS Security - Sample Corner (http://otn.oracle.com/sample_code/deploy/security/9i_security.html)
I ran the SQL script just fine. I�ve Opened the JDeveloper Flile (security.jws) and tried to Make it (following step 2 on "Run the Application using JDeveloper Environmentinstructions" in the README ) but i get this error:
Error: unable to copy to output directory, web.xml not found
It seems that i need the web.xml to run this application, but in the zip file i cannot find any XML file.
What can i do?.
Thanks in advance for your help

Hi,
the problem seems not to be within your application but in missing files on your embedded OC4J. Just try and unzip the JDeveloper 10.1.3 install again.

Your database system may well have a setting for character encoding when creating new databases. If you set that to unicode JDBC should store and retrieve UNICODE strings automatically.
As to the HTML side, you should generally use UTF-8 encoding. You need an editor which understands UTF-8. JSPs and servlets have ways of specifying the encoding which goes into the http headers. For static HTML pages you may have to add a header like:
<META http-equiv="Content-type" value="text/HTML; charset=UTF-8">
When receiving form data you need to do
request.setCharacterEncoding("UTF-8");

How to store files in mysql database using JSP?

I'm developing an online recruitment system using JSP in server side. For the users who registers in it, I want them to upload their cv's from the web site so that I can store it in the database..I'm using mysql as the db..
Can I know how to do it.?..or else is there any better way of doing that?
Need a quick reply..Tx

The best way to put data in a database in a JSP is to not do it. Instead, use a Servlet that calls a DataAccessObject. The DAO puts the data in the DB and the servlet gives the data to the DAO. The JSP does nothing but display results.
Take a google for JSP MVC and DAO. BalusC has a great example of DAO and a JSP that uses one on his blog.

Likely you're querying only one selected value from the request using HttpServletRequest#getParameter() instead of an array of selected values using HttpServletRequest#getParameterValues().
