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.

Passing data from jsp/servlet to a Tuxedo Service thru VIEW

Hi..
We are using Tuxedo10g R3 on AIX 5.3..
We have a Tuxedo Service running which takes values from the VIEW and converts that to upper case.. From the jsp page v r passing values to the VIEW fields which will be accepted by the service..
For testing v checked the service with a tuxedo client and it is working fine..
We have defined a jolt repository file for this service and finished bulkloading and coded the servlet also.. After passing the datas from the jsp, the Tuxedo service is called and it is ended.. but in the service only blank values are passed or the datas are not passed to VIEW fields.. It is not showing any error..
The repository file for this service:
service=NSIMPSRV
export=true
inbuf=VIEW
inview=sample
outbuf=STRING
param=FIRSTSTR
type=string
access=in
param=SECONDSTR
type=string
access=in
param=THIRDSTR
type=string
access=in
param=S-FIRST
type=string
access=out
param=S-SECOND
type=string
access=out
param=S-THIRD
type=string
access=out
and the servlet code for this service:
Result result1;
ServletSessionPool servletsession = (ServletSessionPool) joltsession.getSessionPool("demojoltpool");
ServletDataSet joltdataset = new ServletDataSet();
joltdataset.setValue("FIRSTSTR","Testing");
joltdataset.setValue("SECONDSTR","Tuxedo");
joltdataset.setValue("THIRDSTR","Views");
result1 = servletsession.call("NSIMPSRV", joltdataset, null);
System.out.println("FIRSTSTR:"+result1.getValue("S-FIRST",""));
System.out.println("SECONDSTR:"+result1.getValue("S-SECOND",""));
System.out.println("THIRDSTR:"+result1.getValue("S-THIRD",""));
we are not sure why the datas have not been passed.. do anyone have any idea regarding this??
Thanks..

How does a JSP page send data to a servlet?

I know, elementary school question, but I can't seem to do it no matter what I tried to do. Here is my code:
       URL url = new URL("http://" + ChatGlobals.SERVER_NAME + "/" +
                ChatGlobals.SERVLET_PATH + "/ppowell.ChatServlet?message=" +
                URLEncoder.encode("/a " + cookieArray.getValue())
out.println("<P>" + url.toString());
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setDoInput(true);     // NOT REALLY INTERESTED IN INPUT BUT MUST BE TRUE
conn.setDoOutput(false);     // NO OUTPUT
conn.setUseCaches(false);
conn.setDefaultUseCaches(false);
conn.setRequestProperty("Content-type", "text/plain");
     * Do servlet connection to retrieve from ChatServlet URL instance
     * by instantiating an InputStreamReader object
     * @see ChatServlet
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String stuff = null;
stuff = in.readLine();
out.print(stuff);
in.close();
in = null;
conn = null;
Upon running this code my page just locks up.. URL: http://www.myjavaserver.com/~ppowell/chat.jsp
But if I call the servlet directly:
http://www.myjavaserver.com/servlet/ppowell.ChatServlet?message=/a+Phil
Everything works perfectly, no lockups, no errors, the log and txt files are created. So if my browser calls the servlet everything is ok, but my JSP script in the same directory as my servlet is the one that needs to call the servlet.
How then does a JSP send data to a servlet?
Please help, I've been searching in books and online resources for days now with absolutely no apparent luck to do it.
Thanx
Phil

It's correct that a JSP is compiled to a servlet. All HTTP servlets receive requests and send responses via HTTP, of course.
But this JSP is making a URL connection to a servlet and sending data.
Are you sure that the URL your JSP creates is identical to the one that works in your browser? Have you printed it out to stdout to verify that it's true? (Code inspection and "it looks right" doesn't count.)
Why are you doing it this way? It's common to have a JSP send to a servlet, but the usual way of doing it is to put an HTML form in the JSP, including an HTML <input type="submit">, and POSTing the form data to a servlet URL. Why aren't you doing that? - MOD

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......
}

How to Hightlight the Data in Jsp Page

How to Hightlight the Data in Jsp Page,
I am doing doing search page,based on values given search page those are sent to servlet,in servlet based on some conditions if particuler id i am getting then i am redirecting to Respective jsp page with highlight the data from database..
Thanks in advance...

"Highlighting data in JSP sounds strange".
Without looking at your search specific algorithms I feel you are finally going to display a page (HTML content) to user which contains highlighted text. Highlighting is not directly related to server side language you use (JSP, ASP, PHP etc.). This is purely HTML and CSS. However, server side script (such as JSP) should generate HTML content for getting highlight effect.
Following HTML shows highlighted text using background-color property on span element.
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
</head>
<body>
      <p style="font-size:1.1em">This is a long paragraph which contains <span style="background-color: yellow;">highlighted text</span> and non highlighted text.</p>
</body>
</html>Thanks,

Reporting Services (SSRS) connecting to a Tabular data model: losing formatting

Hi all,
we are developing a SSAS Tabular data model to enable users to connect to it via:
- excel pivot table
- power view reports
- reporting services reports
We invested a lot of time in correctly setting the format of the different columns directly in the data model, in order to have the same consistence format layout in all the reporting clients. For example currencies column with no decimals and with thousand
separator, percentage with just 1 decimal and with the % symbol, date in short date format and so on.
The same with KPIs: for every KPI we decided in the data model which representation to use
When using excel pivot table or power view reports everything works ad expected.
When using Reporting Services instead all the formatting chosend in the data model is gone and also the KPI representations. Why? Is there a way to have them also in SSRS?
Thank you,
Roberto

Hi jdb09,
Your issue can be caused by many factors, it can be caused by the connection string is not correct, please check to make sure the it is correct.
Please check details information below to make sure you have done the correct connection and configuration first:

Dates in JSP page

I have some dates fields on JSP page I want to store data in mysql databse. Can someone tell me how I can format dates as I do for other data types in servlet before I send data to add in databse: such as
For int type data:
String paymentID = request.getParameter("PaymentID")
I format it like this for class Payment.
Payment newPayment(int.parseInt(paymentID)
how do i work with date fields this is what I Am trying to do:
Code patches....
import java.text.DateFormat;\import java.text.ParseException;
public date date1;
try
      date1= format.parse(paymentStartDate);
catch(ParseException pe)
System.out.println("Problem found");
....I do not get any error but it leaves date fields empty because date1 formatting never goes to try... Always say "Problem found on console"
Any help?

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

Jsp-servlet-bean problem

Please help!
I have a servlet controller, a javabean for the data and a jsp for the view.
I cannot get the jsp using
<jsp:useBean id="pList" class="bbs.PostListCommand" scope="request" />
to access the bean data
However, when I access the bean in this way
<%@ page import="bbs.PostListCommand" %>
// html
<% bbs.PostListCommand postList = null;
synchronized(session){
     postList = (bbs.PostListCommand) session.getAttribute("PostListCommand");
     if (postList == null){ %>
          <H1>Nothing in request scope to retrieve ....</H1>
          <P>
<%     }
     else{ %>
          <TABLE border="1">
// etc
� it works
Does anyone know why the <jsp:useBean> tag does not find the bean
I have installed tomcat 4.18 and set the environmental variables etc.
Directory structure is
E:\Tomcat41\webapps\examples\WEB-INF\jsp          for jsp�s
E:\Tomcat41\webapps\examples\WEB-INF\classes\bbs     for bean and servlets
Thanks in advance for any help.
Chris

GrayMan - Thanks for your help.
Let me explain my problem in more detail ...
Background:
I have some servlet experience, but I am new to jsp - so sorry if this seems trivial to you ...
I have a book called bitter java by bruce tate from manning.com . I am trying to get the chapter 3 examples to work
There are three files
PostListCommand          the bean
PostListController     the servlet
PostListResults          jsp
And a new test file � PostListResults version 2 with scriptlet code to access the bean.
There are a couple of typos in the downloaded source files, but nothing that causes the main problem of not being able to access the bean data.
Program flow
Servlet instantiates new bean
Bean � gets data from db
Servlet passes bean to jsp with a forward
Jsp outputs data
I have put the files in the directories �
E:\Tomcat41\webapps\examples\WEB-INF\jsp          for jsp�s
E:\Tomcat41\webapps\examples\WEB-INF\classes\bbs     for bean and servlets
The complete source code for each file is given below.
1 I have checked the db access � that�s ok
2 I have also checked reading the bean data back in from the request scope and printing out the results from within the servlet.- ok
3 I can access the data through a scriptlet (PostListResults version 2), but not with the original PostListResults which uses <jsp:useBean>
thanks in advance, chris

Jsp / Servlet / bean / upload

Hello,
I use a jsp to enter several fields. These fields are sent to a servlet by using a bean (recorded in the current session). Until now there is no problem. The servlet receives all information. Now I must also send 5 files which must be stored on the server. I have thus to add in my jsp 5 file fields.
My question :
Is it possible to integrate the FileUpload package for uploader my files without anything to change in my code (by using of a bean to exchange the data between my jsp and my servlet). ??
In other words, it is possible to use my bean to also transport files. ??
Tank u for u help

Yes it is possible..
download cos.jar from www.oreily.com for file upload..
it will read dat from the form as two parts ..
parameter part and file part..
and you can implement it throgh a servlet easily..

JSP- Servlet-- Bean-- JSP how to implement

I have problem.
My JSP will take a emplyee id .
Now I want to show all the values regarding that employee in a JSP(JSP form) from the DB(Oracle).
So Iam planning like
JSP-->Servlet-->Bean-->JSP
So my doubts are.
1. Is it correct approach
2.If it is correct then which part of the flow connects to DB and stores the value before putting to JSP.
Iam using Tomcat 4.31
Plz help me

What you are probably proposing is an MVC design pattern. I wonder if u have heard of the struts framework. Sruts uses MVC design pattern wherein the servlet u are talking about acts as a controller(C) and the bean acts as the model(M) .The JSPs present the view(V). Hence the name MVC.
Your approach is right. First get the employee ID from the jsp and get the corresponding data from database(This logic u implement in the servlet). Then save the fetched data in a bean so that the result jsp can fetch data from it.
Now this is not a strict MVC approach.
Learn more about struts. It presents a much more cleaner solution.

JSP Servlet and convert the result set of an SQL Query To XML file

Hi all
I have a problem to export my SQL query is resulty into an XML file I had fixed my servlet and JSP so that i can display all the records into my database and that the goal .Now I want to get the result set into JSP so that i can create an XML file from that result set from the jsp code.
thisis my servlet which will call the jsp page and the jsp just behind it.

This is how i used to create an XML file in a JSP page only without JSP/SERVLET concept:
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%
// Identify a carriage return character for each output line
int iLf = 10;
char cLf = (*char*)iLf;
// Create a new empty binary file, which will content XML output
File outputFile = *new* File("C:\\Users\\user\\workspace1\\demo\\WebContent\\YourFileName.xml");
//outputFile.createNewFile();
FileWriter outfile = *new* FileWriter(outputFile);
// the header for XML file
outfile.write("<?xml version='1.0' encoding='ISO-8859-1'?>"+cLf);
try {
// Define connection string and make a connection to database
Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/SAMPLE","app","app");
Statement stat = conn.createStatement();
// Create a recordset
ResultSet rset = stat.executeQuery("Select * From posts");
// Expecting at least one record
*if*( !rset.next() ) {
*throw* *new* IllegalArgumentException("No data found for the posts table");
outfile.write("<Table>"+cLf);
// Parse our recordset
// Parse our recordset
*while*(rset.next()) {
outfile.write("<posts>"+cLf);
outfile.write("<postname>" + rset.getString("postname") +"</postname>"+cLf);
outfile.write("<comments>" + rset.getString("comments") +"</comments>"+cLf);
outfile.write("</posts>"+cLf);
outfile.write("</Table>"+cLf);
// Everything must be closed
rset.close();
stat.close();
conn.close();
outfile.close();
catch( Exception er ) {
%>

Please state your problem that you are having more clearly so we can help.
I looked at your code I here are a few things you might consider:
It looks like you are putting freely typed-in comments from end-users into an xml document.
The problem with this is that the user may enter characters in his text that have special meaning
to xml and will have to be escaped correctly. Some of these characters are less than character, greater than character and ampersand character.
You may also have a similiar problem displaying them on your JSP page since there may be special characters that JSP has.
You will have to read up on how to deal with these special characters (I dont remember what the rules are). I seem to recall
if you use CDATA in your xml, you dont have to deal with those characters (I may be wrong).
When you finish writing your code, test it by entering all keyboard characters to make sure they are processed, stored in the database,
and re-displayed correctly.
Also, it looks like you are putting business logic in your JSP page (creating an xml file).
The JSP page is for displaying data ONLY and submitting back to a servlet. Put all your business logic in the servlet. Putting business logic in JSP is considered bad coding and will cause you many hours of headache trying to debug it. Also note: java scriptlets in a JSP page are only run when the JSP page is compiled into a servlet by java. It does not run after its compiled and therefore you cant call java functions after the JSP page is displayed to the client.

Sending binary data from JSP (1.1)

Hi all:
I am using Tomcat 3.2.1 and Apache under Linux Mandrake OS.
I have a JSP (1.1) sending binary data (GIF, PDF, DOC ..) using response.getOutputStream().write(data)
method.
The problem is the precompiler automatically creates the JspWriter and puts some out.write("\r\n") lines
before I use getOutputStream method. The JVM throws an IllegalStateException because I am using both
methods (this is from Servlet 2.2 specification).
Must I change my code to forwarding to a servlet that make this work or is there a simple solution to
avoid this?
Thanks in advance.

Hi Shreeharsha
Please refer to below docs for sending data from JSP page to RFC. In which you need to use sap connectors for connecting to SAP backend system.
