I am trying to export a DB record to an excel sheet. Below is the code which I tried. I am not getting any error but still only the first record of the table is getting inserted into the excel sheet. But when I try printing, I prints all the records. Below is the code I did to insert records.
I have a JSP and Java program which will read data from Excel and add them dynamically to create table.My requirement is i should able to edit the columns what ever the data that was fetched from Excel and export those contents to another excel file.This should happen on clicking a button, i mean to exporting the contents of the table.
As of now am using icefaces 1.8.2 provided tags for downloading data into excel sheet where i can download all the data from a data table. But now the requirement is like need to download the data into excel sheet based on values passed from UI as parameters to the action class method.
how to export a full jsf page to PDF. In my jsf page, I have a button to export to PDF and some fields where I am retrieving the values from a database. The form is ready but I don't know how to program code or program a button to export the page to PDF. I tried to search for an easy and a standard way but unfortunately I didn't find any useful example or code.

My app uses docx4J, XStream, and also uses an image on the start page. I placed all of this external libraries in Java Buid Path and in Eclipse it all works well but when I export all data to runnable jar file it doesn't work.

I'm making an import/export of xml - I have the import of xml sorted I'm just trying to finish off the export. My export class is called XmlWriter.java. Inside the class I have an updateFile method to update an xml file as such:
public void updateFile(Environment environment,Document doc) { // code }
I then in my main method have
public static void main(String argv[]){ //declare new object of class XmlWriter xmlWriter = new XmlWriter(); //test testUpdate method // xmlWriter.testUpdate(); Environment environment = ;
[code]....
I don't know what to make my variables equal to - eclipse keeps trying to use null but obviously that won't work. The Environment is another class that just contains getters and setters for the 3 different databases (that are in the xml file) and the getter/setter for the environment ID (also in xml file).
I have a library that I'm writing, the library contains a spring xml configuration file (lets say it's called libraryContext.xml) that sets the library up correctly for runtime, it also includes a test spring xml file that sets the library up for test by importing libraryContext.xml and overriding certain dependency injection beans (the library basically connects to a real database under normal conditions and uses dummy DAO's under test conditions). That bit is all fine.
The thing is, when I build the jar for the library (lets say it's called library-0.1.jar), the jar does not seem to contain the libraryContext.xml and that means that I can't import library.xml into my applications context.xml.
Basically, I have this line in my applications context.xml
Unsurprisingly, since the xml file is not contained in the library-0.1.jar, the error I get is,
Java Code:
Offending resource: class path resource [applicationContext.xml]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [libraryContext.xml]; nested exception is java.io.FileNotFoundException: class path resource [libraryContext.xml] cannot be opened because it does not exist mh_sh_highlight_all('java');
With respect to potential solutions to the above problem, I could:
1) physically copy the libraryContext.xml file (and its other *.xml and *.properties dependencies) into the application, but then I'd have to maintain duplicate files - I don't like this option.
2) find out if there is a better way to handle this problem from people who know better. E.g. is there a way to embed the libraryContext.xml file (and it's dependencies) into the jar file so that it can then be imported into the application. I've spent a while on google trying to figure this out and haven't come up with anything overly useful (perhaps I've been using the wrong search parameters).

I need to retrieve an image from the MySQL DB and display it in my JSP. The code below retrieves and displays the image with success. But, an exception is thrown:

how can I resolve the cause with the getOutputStream() and prevent this exception to occur?
I've got another project for a course and am stuck. I've debugged and tried to figure out where it is breaking, but I just can't find it. I've used this connection code block as well as the contstructors before, but this just won't work. I've got a tab that should send all of the information to a MySql database upon the click of 'Add Employee'. I've given my connection string, the addEmployee(); code, and if needed I can include the subclass code. I've got a superclass 'Employee' and a subclass 'Salaried' that uses four attributes from 'Employee'.
private void btnAddActionPerformed(java.awt.event.ActionEvent evt) { addEmployee(); } public void addEmployee() { int socialSecurity = 0; boolean error = false;

I have written a java application that retrieves data from a database and display it on a graph. What i want is that the two systems are synchronized in such a way that when we update a value in the database, it is immediately shown on the graph.i have tried to use a refresh button but decided this would increase the overhead.

I am having a problem to connect my .exe file to the database(mysql). I used launch4j to convert the jar file to .exe but the jar file can connect to the database when running inside the dist folder. When I run the .exe I am getting this error: No suitable driver found for jdbc:mysql.
private void btnAktualisierenActionPerformed(java.awt.event.ActionEvent evt) { if(sql.conOK) { tabelle.table.tableChanged(null); tablePanel.remove(scrollPanel); // The following fetches the new database data and adds the new jFrame tableExists = false; this.getTable(); tabelle.setOptions(); } else lblStatusCon.setText("Bitte zur Datenbank verbinden."); }
this is what I've been doing. It shows only the new jTable when I resize the window.
