java - JExcel Warning: Could not add cell at A257 because it exceeds the maximum column limit' -


I asked to add the average amount of data in my web-app (basically a list from SQL) to download Was the Excel file, so I did a servlet to generate Excel.

The problem is that the jxl API does not like more than 256 rows, and my data is more than thousands

Is there any way to go around this limit? If I could, I would like to use this API (there is no need to set up a separate API in the server and it is easy to use). But if I want I will change

Thanks for all!

PS: Here is the main code of servlet: 

  list & gt; Table project & gt; Sql = (list & gt; TableProject & gt;) session.getAttribute ("sql"); Response.setContentType ("application / vnd.ms-excel"); Response.setHeader ("content-displacement", "attachment; file name = export .xls"); W = workbook Secure Workbook (response.getOutputStream ()); S = w.createSheet ("Consultation Project", 0); For (int i = 0; i & lt; sql.size (); i ++) {S.Dedel (new label (i, 0, sql.get (i) .getCod_project ())); S.addCell (new label (i, 1, sql.get (i) .gettext_project ())); S.addCell (new label (i, 2, sql.get (i) .getDate_notification ())); S.addCell (new label (i, 3, sql.get (i) .getDate_last_action ())); S.addCell (new label (i, 4, sql.get (i) .getTxt_personal ())); S.addCell (new label (i, 5, sql.get (i) .gettext_estate ())); S.addCell (new label (i, 6, sql.get (i) .getTxt_provider ())); } W.close (); W = null;  

  s.addCell (new label (i, 0, sql.get (I) .getCod_project ()));

should be 

  s.addCell (new label (0, i, sql.get (i) .getcod_project ()));

And so on, this is not the line limit you are facing, but the column border. Check out.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
