All things are correct it is giving error in the below code of line final JFreeChart chart = ChartFactory.createAreaChart("Area Chart", "", "Value", dataset, PlotOrientation.VERTICAL,true, true, false); telling that The method createAreaChart(String, String, String, CategoryDataset, PlotOrientation, boolean, boolean, boolean) in the type ChartFactory is not applicable for the arguments (String, String, String, CategoryDataset, PlotOrientation, boolean, boolean, boolean) everything is correct seems, dont bother about the names these are correct, also CategoryDataset and the PlotOrientation are correct I have given the warning and error in the underline lines above. |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Regards Chandan

Hi All,

I am little bit new to struts framework though I have used tiles in struts application. Now I want to display charts in my application. After searching I found jFreechart library to create charts. (Though it doesn't generate all the charts, like box in web application).

Now I also found some link on how to use jFreechart in struts application. Though the post are not much descriptive, I tried in the same way to incorporate the chart functionality but it is not working......

Can someone please provide the entries to be made in [B]struts.xml[/B], [B]web.xml[/B] to make this functionality work.

Pls find below the different files I am using to run my application.
I have made the changes that I made for graph functionality in bold

Hi Richard, Now its more clear...... Thanks

Thanks Richard..... But I was expecting some live example to get the clear understanding... Its now done by using the below way just creating the object of struct tm and then giving the values to the variables of the structure adding the days to the tm_mday variable using the mktime() function, converting it back to a structure..... and then accessing the required values with the structure variable... I still want to understand the use of the time_t.......if u can......

Sir Thanks for your reply I am working on linux.... and the link you have given... I dont find any function which can add some day to the particular date to give new date. Thanks

Hi All, I want a C programme which will take a user input as a date and number of days, and then it will add the given number of days to the input date and will give the resulted date. It should keep in mind all the permutation and combinations like changing month year , leap year, some months have 31 days some have 30 days etc.... for eg.: input date 2010-12-25 days 20 result 2011-01-14 This programme can be made but this will take a lot of time if anybody has similar to that or exact programme then please help.... its just a module. Thanks

Hi, I have an hdf (extension )file , i need to read that file and convert it into an ASCII format using C program. The problem is small but not finding a way. Thanks

Hi All, I want to declare memory dynamically for a 2 dimensional array. and then want to use that pointer like an array. as i am using ANSI compiler so there is no need to typecast the return type of the memory block returned by malloc() so if i will write the inline code line as arr=malloc (nrows*5*sizeof(int)); its working correctly but i just want to know to be at the safer side that if i will be using the old compiler how to type cast the same as arr=(int [] *)(malloc (nrows*5*sizeof(int))); this is giving error.(i am on linux) thanks

#include
#include
int main()
{
int nrows=2,i,j;
//int arr[nrows][5];
int (*arr)[5];
arr=(int [] *)(malloc (nrows*5*sizeof(int)));

Hi vuyiswa, Thanks for giving so much time i reading this and giving the reply.

I am not able to connect to the database tables as when i enter the login and password it comes to the same login page again without showing any error. Now, I cannot identify whether its due to the following reason:-

How do you know that you cant connect , if you cant see the error ?

Because when i enter hte username and password that there in the database table User_Master[that has been converted to dbo.User_Master] , i cannot loog on to. Inspite it redirects me to the locgin page again. Also I cannot debug the prog as i dont have VS 2008. To check this whats happening , i tried one thing:- On login page [in coding,aspx.cs page], i commented the line which checks whether the username and password is valid or not [ which fetches data from the database] and simply redirected to the Homepage.aspx. It works fine. On one page [in coding,aspx.cs page], i commented the line which checks whether the session for userlogin is there or not[in login page if the user is authenticated i have saved his username in session and checked this session on everypage , if the session is not null then only user can see that page]. So now when i browse that page through IIS server the page is opening(ofcourse, it will) i enter all the data in the text fields. When i submit the button [which enters the data to the tables] it gives me that dirty yellow page. [as i said earlier i cannot debug the programme without VS or there is any way]

Because if it connects then there is some problem related with database, and if there is some problem with database then i have redirected it to the Error.aspx page.

what is your Question Regarding this ?

As now i am not using the default D/B provided by the VS2008 and using SQL Server 2005 express edition, so are there any changes i

hi All, I just wanted to know the following things if u can just help me. I made a website in Visual Studio 2008 and used the database provided by the VS [I dont know which version is this]. That website runs successfully on the machine having visual studio[As in that i just attach my database through the GUI provided by VS]. Now I want to deploy that website on a LAN. I have the database in .ldf and .mdf format. But I dont know whether it is in sql 2005 or sql 2008[as i made it through Visual Studio GUI] Now the system in which i have to deploy cannot have a licensed product. So i have to convert that database either to open source or an free version of sql server. I chose to go for SQL Server express edition that is free. Now the prolem being whether I use SQL Server 2008 or 2005 as i dont know which database was provided by the VS.[when i made that databse] But the problem being that on the system in which i have to deploy does not contain VS. Supposing it provides SQL Server 2005 express edition I permormed the following test:- Now i have installed .NET framework 3.5, MS SQL server 2005 Express Edition and the SQL Server management studio that is a GUI for handling d/b. Now when I attached that database[that i have, of which i dont have the version]. I can see the database and tbles and all the contents that was there in the d/b.[through that management studio GUI]. Now i have deployed my website on IIS also and when i browse my page i can see it on the browser but ....... I am not able to connect to the database tables as when i enter the login and password it comes to the same login page again without showing any error. Now, I cannot identify whether its due to the following reason:- 1> The database that i have is in SQL server 2008 express edition or something else. 2> I have to make some changes in the connectivity[in web.config or some other location] NOTE: Also when i connected the d/b in management stuio it shows all the tables with dbo as a prefix. for eg. suppose i had a table as User_Master than its showing as dbo.User_Master. please guide me if u can. Waiting for ur reply.
