How Can I Add Pivot Tables of Excel Into JSP Pages

Hello all,
Basing upon a query to database, i wanted to add a Microsoft Excel pivot table functionality in JSP page [with the result of query].
Is it possible to create a Pivot Table in JSP with dynamic data from database ??
Can any body help me in solving this issue ???
Thanks & Regards

There are a few alternatives to doing this (depending on the clients you are serving this page up for).
Going the pure HTML
There is an open source project called JPivot which provides an HTML front end for Pivot Table (using tag libraries)
Going the Microsoft Office route there are a few options:
1) POI HSSF ( http://jakarta.apache.org/poi/index.html) allows you to "update" an existing Pivot table by replacing data values contained in a template pivot table.
2) Use the open source XELEM api (xelem.sourceforge.net) which produces SpreadsheetML (Micorsofts current XML file Format). At present, I don't believe this handles creating a pivot table from scratch (you have to manually create the Pivot Table template, read in the template (with XELEM) and update the data values in the template before writing it out. (the same holds true for POI)
3) Commercially the company I work for (www.workbeans.com) is writing a pure Java Pivot Table API that will allow you to create a Pivot Table in the Excel SpreadsheetML file format from scratch. (supported by Office 2000, XP and 2003). The Pivot table functionality isn't slated until a future release (Oct. 2005), so if you can wait until then we could help you further.
Best,

How can i hand the RowSet to the next jsp page

In a jsp page, I get a RowSet as the following:

Hello Charles,
I did the registration in the same way as in the JDeveloper 3.2.3 (see follows)
// make sure the application is registered
oracle.jbo.html.jsp.JSPApplicationRegistry.registerApplicationFromPropertyFile(session , "ReefBC_BCPackage_BCPackageModule");
The argument ReefBC_BCPackage_BCPackageModule is a property file (ReefBC_BCPackage_BCPackageModule.properties). After some tries, I can still use it in JDeveloper 9i R2. The reason to keep it is that there would be a lot of migration work of javabean calling if I change it to <job:DataWebBean..>. But I am wondering, do I initialize two application modules when I use registerApplicationFromPropertyFile() and <jbo:ApplicationModule..> in the same page.
The problem in doStartTag() is found after I post "http://forums.oracle.com/forums/thread.jsp?forum=83&thread=155210&tstart=75&trange=15", by tracing into the <jbo:ApplicationModule..> after calling the OrdHttpUploadFormData. HtmlServices.getRequestParameters sends back an exception, that breaks the running of the program. It was temperorily solved by extending the ApplicationModuleTag. If <jbo:..> could use the application module initialized by registerApplicationFromPropertyFile(), I guess it may be a better workaround.

How do i import a table from excel into dw8?

I want to import a table from excel into a table in dw8, i
just want the data inside the excel table to be imported to the
table in dw8.
The tables has the same stracture - number of rows and
columns.
is it possible?
btw special paste is no good, since it copies the stracture
of the table from excel which contains <td height="17">,
which is not good coding - td doesn't support the height
option.

table without special paste:
<table width="90%" border="1">

how can i apply this java program for a jsp pagewhy do you want to do this ?
Your program reads from a file on the disk and formats based on a patterm.
Jsp is not intended for such stuff.

How can i pass the same parameter from 1 jsp page to many jsp page?

hello.....
how can i actually pass a parameter from 1 jsp file to many other jsp files? pls help......
thanx

Hi
Save the information which u want to pass to various JSP's inside Session Object.
There is an Object called HttpSession and u can store information inside which other jsp pages within the same domain and same browser instance can use it.
commands which are for ur interests are
<Session Object>.setAttribute("<object name>", <value>);
Example
HttpSession objsession =request.getSession(true); String strName="NEED_HELP":
objSession.setAttribute("Name", strName);
And then u can retreive that information in your n pages.
Read any JSP/Servlet Books and u will know about them
Bye.

How can I use PowerPivot tables like Excel tables -- printing, etc.?

I can't seem to find any information on this anywhere, and even more surprisingly, no one else seems to have even asked this question...
How can I use tables I create in the Excel PowerPivot window in the same ways I use tables that are in ordinary Excel worksheets, to accomplish tasks such as printing? I am able to use the powerful capabilities of PowerPivot to produce tables with precisely
the information I need for reports -- connecting data from multiple tables/sources, filtering, etc. -- but then there doesn't seem to be any way to actually print what I'm seeing, nor can I seem to access cells in these PowerPivot tables from Excel worksheets.
If a PowerPivot table is conceptually an Excel table with additional power in terms of pulling in data and relating it, it would seem appropriate that all the power of Excel could be brought to bear on these PowerPivot tables, but on the contrary, the available
operations are limited. if, instead, a PowerPivot table is more correctly viewed as a data source that Excel worksheets can connect to, that would be fine, and indeed, one
can use a PowerPivot table as a data source -- except it can't be brought into an Excel worksheet as an ordinary Excel table, unlike most other data sources.
I hope I'm missing something really obvious, and that someone can point out what it is. Thanks.

Kirchh,
When PowerPivot was first designed, the decision was to integrate closely to Sharepoint to allow for team sharing. We are constantly evaluating customer feedback to add more features, and this has been one of the feedbacks we have received. We will consider
supporting this in the future but with no gurantee.

I'm not questioning why PowerPivot is closely integrated with SharePoint. I'm asking why connecting to the PowerPivot model from within Excel was intentionally blocked by Microsoft, when all the functionality to do so appears to be present.
Is creating an OLE DB connection in Excel to PowerPivot as $Embedded$ supported?
No support. It was originally designed for SharePoint. This changed with Power Pivot for Excel 2013 (it's packaged with it). Originally the scope (in 2010 through 2012) was that it was for SharePoint users. So it became more obvious through that to market it
toward all Excel users. Thus the recent changes.

How can I add a log in and password protected page on my website

I would like to add a "register now" and login page to my website. Can anyone help with a SIMPLE solution? I've tried to follow the 'secure area' info on BC but not having any success.
I would like to have a 'register/login' button in order for visitors to get to a secure page. How can I make it happen on Muse?
THANK YOU!!

Hi
You may want to refer to discussion here : Adding a Secure Zone to my Muse site
As mentioned, you need to create a secure zone in your Business catalyst site and have a landing page set there only. This cannot be managed from Muse only.
For more details on how to create secure zones and achieve this, you may want to refer to some useful article as mentioned below:
Business Catalyst Help | Add a secure area to your site

I hope this helps.

How can I add a custom attribute to the create page dialog?

I followed the following link to add a custom attribute called starred and this attaribute can be displayed in siteadmin grid
http://dev.day.com/docs/en/cq/current/developing/customize_siteadmin.html
I would like to let the user input the value when they create a page. That's why I would like to add a custom field in the input dialog box as attached pic.
The method you describe before can only added those CQ bulid-in attribute.
For those custom attribute, how can I added it?

Hi,
How can I customize the /bin/wcmcommand or how can I make use of [2] to create a custom WCMCommand?
I think the "formUrl" is to post those input value to the jcr repository?
var createDialog = {
        "jcr:primaryType": "cq:Dialog",
        "id": CQ.Util.createId("cq-createdialog"),
        "title":CQ.I18n.getMessage("Create Page"),
        "formUrl": CQ.shared.HTTP.externalize("/bin/wcmcommand"),
        "params": {
            "cmd":"createPage",
            "_charset_":"utf-8"
I have added a field called "starred"
Moreover, when I using the firebug to trace the post command, I can see that the starred value is posted also.
:status
browser
_charset_
utf-8
cmd
createPage
label
b
parentPath
/content/keyword_elaboration
starred
c
template
/libs/collab/commons/templates/form

However, when I go to the crxde to view the node's attribute, the properity starred is not created
Are there anything I did wrong or missing?
Thanks.

How can I Locate the correct filepath in a jsp page?

In http://localhost:8080/myweb/a.jsp, I will call a java bean file which is locate in http://localhost:8080/myweb/WEB-INF/classes/haha/DBConnection.class. This java file requires to read an external file which locates in http://localhost:8080/myweb/WEB-INF/classes/haha/db.txt
My question is how can I get the correct filepath in this environment?
inputStream = new BufferedReader(new FileReader(????????));
Only this will work
inputStream = new BufferedReader(new FileReader("D:\Program Files\Apache Software Foundation\Tomcat 5.5\db.txt"));
But no one will place the file here, and it is impossible to do this when upload to 3rd party hosting.
Any suggestion? thx.

Thx all, in a jsp page, calling this method is fine.
ServletContext s = getServletContext();
String a = s.getRealPath("/");
In a Servlet file, below method is ready to use:
String b = getServletConfig().getServletContext().getRealPath("/");
My problem is, I have a jsp page, which initialize a java bean , this java file is responsible for Database Connection, which will read the external text file to get the login, password and database name. So I won't need to recompile this file every time when I place in different platform with different configuration. I only need to edit the text file is ok.
But How can I get the absolute file path when that jsp page initialize that java bean file? Below is my error, any suggestions are thx.

How can I pass a variable value from first jsp page to thired jsp page

In my program ,threr are three jsp pages . I want the first pages's variable value in to thired page .How can I acess.
I used the request.getparameter() ,but when I print the value , null value is getting .

request parameters only last for one request.
To save them longer than that you need to save them somewhere.
Couple of alternatives
1 - store them to session
session.setAttribute("username", request.getParameter("username");
2 - create a hidden field on page 2 and store the value from page 1 there. When you submit page2, you can get it on page3 with request.getParameter again.
<input type="hidden" name="username" value="<%= request.getParameter("username") %>">

How can i add a table header using DefaultTableModel?

Im having problems finding examples of creating a table header using the DefaultTableModel. Can anyone point me in the right direction?
so far i am able to create a table and add rows, but i need the first row to be the header with title and i am not able to do that with this model.
Below is an excerpt of what i have thus far...
JTableHeader header = new JTableHeader();
        checkOutTable.setModel(tableModel);
        checkOutTable.setRowSelectionAllowed(true);
private DefaultTableModel tableModel = new DefaultTableModel(
            new Object [][] {
                    {"Item ID", "Title", "Type", "Serial ID", "Status", "Response", "Print"},
                new String [] {
                    "TITLE 1", "TITLE 2", "TITLE 3", "TITLE 4", "TITLE 5", "TITLE 6", "TITLE 7"
            ){Class[] types = new Class[] { java.lang.Object.class,
                    java.lang.Object.class, java.lang.Object.class,
                    java.lang.Object.class, java.lang.Object.class,
                    java.lang.Object.class, java.lang.Object.class };
            public Class getColumnClass(int columnIndex) {
                return types[columnIndex];
            }};

Use the constructor that takes a Vector of column names and a row count.

thank you .

hi
Two add two internal tables data. first we need to create third internal table with all the fields of first two internal tables.
later u move the two internal tables data to third internal table
by looping the internal table which have more records or depending on the requirement and move the corresponding fields of first internal table to the third internal table and use the read statement with condition based on primary key of first itab and get the corresponding data of 2table into 3table.
i am sending the sample code to u.
check it out. i think u will understand how to move.
select vbeln waerk netwr erdat audat kunnr
   into table it_vbeln
   from vbak
   where vbeln in s_vbeln
     and erdat in s_erdat.
if not it_vbeln[] is initial.
select kunnr name1
   into table it_kunnr
   from kna1
   for all entries in it_vbeln
     where kunnr = it_vbeln-kunnr.
endif.
loop at it_vbeln.
clear it_final.
   it_final-vbeln = it_vbeln-vbeln.
   it_final-waerk = it_vbeln-waerk.
   it_final-netwr = it_vbeln-netwr.
   it_final-erdat = it_vbeln-erdat.
   it_final-audat = it_vbeln-audat.
read table it_kunnr with key kunnr = it_vbeln-kunnr.
   it_final-name1 = it_kunnr-name1.
append it_final.
endloop.
