Writing Data To A Static Table - Can't Populate All Fields With Data
Jun 24, 2015I have a program which consist of several classes. The program reads a pom file and parses the data and then writes the data to a static table. The issue I'm having is with writing my LIB file data to my table. In the HtmlDataTable Class Im trying to write the files that are read in the lib directory to the table. My table currently consist of 3 columns (missing jar files,Lib Directory files, and POM file data) currently Im only able to write the missing jar files data to my table. In the HtmlDataTable class there is a for statement where I write the missing jar file data to my table. Im also trying to write the contents of the Lib directory within this statement as well. This is where I'm having my issue. My other classes consist of a SAX parser which parses the xml file, a class that creates my static table and a class that compares the jar files in my lib directory to the jar files in my pom file. . Theres a lot of code so I included the parts I felt were useful. If needed I can include the other classes as well.
public class ReadPomFile extends DefaultHandler {
public static void main(String[] args) {
try {
// obtain a SAX based parser to parse XML document

Enterprise JavaBeans :: How To Refresh JPA Data When Table Data Is Updated From Backend
Nov 27, 2012Is there a way to inform the Entity Manager or force the JPA provider to reload data from the database? The scenario could be data being updated by a store procedure or direct SQLPlus maintenance, without restarting the Application Server, the JPA need to load the newly updated data from the database.
I think the current JPA API is not enough. The void refresh(java.lang.Object entity) from EntityManager need to pass in the Entity object, I will like to know how to refresh the entire JPA Entity data after the physical table data being update from backend.

JSP :: Download Data In Different Sheets In Excel
May 27, 2010I have a requirement to download the data from DB to CSV/Excel. What I did is retrieving all the records from DB and store in the List and pass that list to the jsp page. In JSP page, I am using the below setting to download it to CSV/EXCEL.
response.setContentType("application/vnd.ms-excel");
String fileName = "Report"+System.currentTimeMillis()+".xls";
response.setHeader("Content-disposition","attachment;filename="+fileName);
It was working fine. But I have an issues in it. Excel is capable of storing it only 65,536 rows. Even all the data getting downloaded to CSV/excel (> 65,536), while saving I am getting error from excel saying that it can't save more than 65,536 rows and the below data won't be saved.
This workbook contains data in cells outside of the row and column limit of the selected file format.
Data beyond 256 (IV) columns by 65,536 rows will not be saved.
Formula references to data in this region will return a #REF! error.
I am not opt for POI apache third party at this point of time. Is it possible to download it in other sheets if it exceeds the max limit.
Example: Having data of around 100,000.
Download 65,536 - Sheet 1
Remaining in Sheet 2,3.. of the same excel.

Value Format While Reading Excel Data Into Java
Jan 20, 2015I am reading Excel data using java apache. I got format issue while reading double value such as 869.87929 (in excel) into 869.8792899999999 (in java).
I'm using following files to read excel data.
1. Schema.csv: SheetName,2-int-Double
2. File.xls:
col1 | col2
123 | 869.87929
Sample code:
if(type.equals("Double")){
String str = content[i-1];
//System.out.println(str);
BigDecimal d = new BigDecimal(str);
listObjects.add(d);
}
Note: type from schema.csv & content [] value from file.xls
If I print **str**, it shows value as 869.8792899999999.
But i need to get **str** value as 869.87929. How can I get it?

Auto Click And Auto Populate Data
Sep 26, 2014I am working on a project named as "Auto Click and Populate". This is link is like online feedback form / surveys which we program. I have a link with me which is mentioned below and there will be a counter box which will hit the link that much number of times.
Inputs:
-A text box having this link.
-A numeric box having counter number i.e. the number of times the link should be processed.
-A button named as process which will INITIATE the process.
Now say if I input 10 into the numeric box; the attached file contain link should be processed 10 times and the question which is coming on the link should be answered randomly out of the options which are present. For ex: When you will hit a link; the first question will be gender in that 3 options are present "Male", "Female" and "Prefer not to answer"; either of 1 out of 3 should be punched automatically and proceed automatically ahead. The punch(es) will be stored in database which is maintained at my end.I have done research and till now found the code for auto click only and not for auto process.

How To Get Data Inside Table Row When That Row Is Clicked
Dec 19, 2014I am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file
