One relatively easy way would be to use a JSP tag, like this one.

Enable paging in tabular data in JSP/Servlet

i have a JSP page which will show the list of records from the database.
and i can do a buld delete of these records.
what i have done is this jsp page calls a servlet once i check some values and press the delete button. this servlet will delete the selected rows and sow the values deleted.
now when i come back to my jsp page and refresh it, i can see that values being removed from the list.
now i want to do the following things
1) Automatically refresh my jsp page when i click the delete button and don't want to be redirected to a page.
2) i want to enable paging. hope those who have worked with asp.net grid view understand this.
thx

If you are familiar with ASP.NET you should probably consider using Netbeans 5.5 with the visual web pack plugin.
http://www.netbeans.org/products/visualweb
It's currently a preview, but should be released "soon"
It features drag and drop web app development and a paged control like the one you are looking for. Much simpler than using the manual old jsp/servlet route.
The latest Oracle JDeveloper also support visual web app development with these types of components.

How can i display data on tha same page in jsp/servlet

Hello friend,
I am storing 50 items in a dataBase. i ve two buttons/links name previous and next. i ve to display 10 items each time in the same page when i click next button and the revrese for previous. through JSP/Servlet.
Any suggestions will be appreciated.
chintan anand

I'm not sure this is the best practice... try to add the item in the arraylist, then when u click next button, add 10 to the counter. subtract if it is a previous button. thats it!
ex..
for(int x=counter;x<=arraylist.lenght();x++)
....print item here......

Using JSP/Servlet to write Word Document to BLOB

Hi
I need some help pls
When I use a normal class with a main method, it loads the word document into a blob and I can read this 100%.Stunning.
With a JSP/Servlet I cannot get the document out again. The "format" seems to be lost.

hello,
there are multiple documents out there, describing the oracle reports server setup. try doc.oracle.com for documentation.
also it is part of the online-documentation.
you need to install 9iAS enterprise edition. the server is pre-configured and will listen to the url http://yourserver/dev60cgi/rwcgi60.exe
passing only this url you will get a help-screen, describing the syntax.
regards,
the oracle reports team

How can I call EJB from JSP/Servlets in iWS?

Hi!!
My JSP/Servlets are on iWS, and I deploy EJB on iAS.
In this case, I don't know how JSP/Servlet call EJb on iAS.
I'd like to know how I can set JNDI name in JSP/Servlet on iWS.
I will thank you if you give me a simple example source using JSP/Servlet
and EJB.
Thanks in advance!!!
- Park-

Park,
Why Are you running your JSP/Servlets in iWS instead of iAS? For whatever
reason,
look at the Converter sample from iAS. You will be doing RMI/IIOP in this
case and the sample explains in detail what to do.

How to use connection pool in jsp/servlet ?

I found I can "lookup" it in either java beans/servlets/JSP using JNDI. why?
what is the best practice to use it in a jsp/servlet web app considering JNDI lookuping expensive?
Thanks!
Bo

Edited by: BobXu on Nov 17, 2008 2:32 PM

Huh?
You can lookup a JNDI resource from anywhere in java code you want to. As long as you have a repository set up to search on :-)
Of course whether that resource is available or not is a different matter. If you let the server set up the JNDI resource for you, then you can't run it standalone outside the server without something else setting the same thing up :-)
So its not so much a limitation of beans, but just the environment you run the code in.
Best practice? Don't write sql queries in JSP pages :-)
For the rest you might consider the DAO pattern. Or ignore SQL altogether and let hibernate do the work there for you.

How to implement this function in JSP/Servlet env?

Hi all,
I working on a project, it provides functionality to upload file using JSP/Servlet. In the first JSP page, there is file location and submit button. After user select a file to upload and click submit button, a message, like "sending file to XXXX", will be shown on the screen. Once uploading and validation are done on the server-side, a successful/error msg will be shown to user.
Here I have a question for the "sending..." msg and the successful/error msg. They should be put in one jsp page or in two separate page? how to implement them?
Thanks for any help!
Tranquil

For the sending message... Well, the thing is, when you click submit, it's sending the file to the server and the server is processing it, and this is all done before the "complete" page is sent to the server. So one would need to use some Javascript on the page before the actual submit happens to show some message. This is done on Ebay when you put something for sale, you can upload an image, and there is a little popup message telling you that it's uploading, and it is removed when the process is done. Now, I'm not sure the exact details of how this works, but my educated guess is this:
1) The onsubmit function of the form checks that the file upload fields have a value (no need to popup a message if no file upload, since that's what usually takes the time, although it could just be assumed there is a file). If a file is to be uploaded, or just want to show the message anyway, a new popup window is opened with the window.open method and the "sending" message is shown (either written via Javascript or just load a small web page to the window).
2) The popup window, since you can't transfer the window object from the form page to the next page, has to check window.opener for some value that the success/error page would have to set. The success/error page could use it's body onload function to set a variable in it's own window object to denote that the page is loaded. The popup window can use a looping check using setTimeout or setInterval in Javascript to check for window.opener.isLoadedVariable to be present, and if so, close itself.
I've never done that, but I see no reason why it wouldn't work.

You need to use the Oracle jdbc driver. Apparently, the Weblogic JDBC driver is being selected:
weblogic.jdbc.rmi.SerialPreparedStatement
The Oracle JDBC classes can be found in <ORACLE_HOME>/jdbc/lib/See <ORACLE_HOME>/jdbc/readme.txt for how to specify the correct class path in the application.
I would have thought that the oracle JDBC driver would have been selected (if in the classpath) or an exception would be raised if the Oracle JDBC driver was not found.... because the code should include:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
This should load the Oracle jdbc driver and classes, not the weblogic ones. IF the Oracle JDBC drivers are not found, an exception should be raised...

File upload and download using jsp/servlets

How to upload any file to the server using jsp/servlets. . Help me out

You can also try the Jenkov HTTP Multipart File Upload. It's a servlet filter that is easy to add to your web-project. After adding it, you can access both request parameters and the uploaded files easily. It's more transparent than Apache Commons File Upload. There is sufficient documentation to get you started, and there is a forum if you have any questions.
Jenkov HTTP Multipart File Upload is available under the Apache license, meaning its free to use.

Separate jsp/servlets from EJBs for petstore

By default, petstore deploy all the web apps and EJBs in one ear. I am trying to
separate the JSP/servlets to deploy to diffent machine. I need to modify the client
InitialContext to point to the remote server. I took a look at the source and
there are many places using the default constructor of InitialContext to load
the default URL. I wrote a jndi.properties file that has the correct url and put
this to the classpath. I know this file needs to be put to the working directory,
too. In case of pet store web application, what should be the working directory?
Thanks, Cathy

I'm also interested in running the Pet Store application server and the database
(Oracle prefered) on different systems.
Is this configurable during runtime or does it require code modification, compilation
and deployment?
Thanks,
TL
