View Replies View RelatedI have a program that allows the user to select what type (i.e. tif, jpg, sid) of file they have to load. I use a JCombo box for the selection type. I send this JCombo box string to my ElevationConvert class. What I want to do is check to see if that extension the user selected exists prior to converting it. If the file extension does not exist, I want to pop up a window (JOptionPane) stating is does not exit. I have tried suggestions found on this site, but does not seem to work for my application. The program works with (Process cN = Runtime), if I try not to check for the extension. But when I add the check for (If, else), it bombs. This executable runs in the main folder. The file extensions are in a subfolder called Ned.

I am currently working on an application with java and I want to do is upload and download details in .xlsx file. Uploading process is successfully worked but the problem is that when I download the file .xlsx with details at opening the file it gives me the following message :
Excel cannot open the file '(filename)'.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.
I need to be able to select a file (compressed), change its file extension (to zip) and load all its content, preferably as objects. If it makes things easier one can assume all these files to be of the same type.
The content of the zip file are placed in folders, known Beforehand which might make things easier.
Using Netbeans 7.4, I have hand coded a GUI (SE desktop distributable application), created a single table database (Java DB using 'Embedded Driver' connection).
As I'm at that stage of creating a (non-CRUD) database application using Hibernate 2.0, is it possible to use the Java DB/Embedded Driver with Hibernate or does it need to be a 'localhost' connection?
I'm trying to make a search engine that will search my computer given a path with any options i decide. So if i decides to look for the file name "resume" with extension "pdf", it will give me the files in the directory, including subfiles.

I'm reasonably new to Java and NetBeans.
I'm developing an SE Java application which allows the user to view a database that I've created. I've done the data binding to a JTable but don't see any data. I've read the Derby/Java DB manual and it seems that I need to put data into this Embedded database (single table). All I want to know is how to put the data in - can I copy the files from '.netbeans-derby' folder or do I have to utilise another method?
for a project im doing i need to create a java app with an embedded database so that the datbase is part of the application instead of run on a server that the app talks to.
the problem im having is finding the documentation for this, ive found the following 2 tutorials that almost do what i need:
NetBeans Platform CRUD Application Tutorial Working with the Java DB (Derby) Database.
how i can accomplish embedding a database into a java app.
I have an embedded browser in a standalone java app running on windows. The browser calls up web pages over the internet with no problem.
import org.eclipse.swt.browser.Browser;
final Browser browser = new Browser(group01, SWT.NONE);
browser.setBounds(0, 0, 1000, 400);
browser.setVisible(true);
browser.pack();
browser.setUrl(texturl.getText());
I have a C executable which captures and documents network traffic. I communicate with it by entering http://27.0.0.1:6500 into any browser (it works with them all). It responds with a simple html form (three buttons, a tick box, a label, and one text box).However I cannot get it to work with the embedded SWT browser.
i have a run time error that could not find or load the main file java .

I am working in JSF and I've forgot few of the basics :'I use eclipse IDE to develope JSF projects. When I used to create a JSF file, it's extension is basically .jsp and when I ran that file in server .jsf extension used to be displayed in url. But recently, when I did the same thing I got .jsp extension in browser. in web.xml
when url-pattern is the following, .jsp extension is shown, eg: FileName.jsp
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
but when I change the url-pattern as per following, .jsf extention is shown , eg: FileName.jsf
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
even if I change the url-pattern to abc or xyz, the webpage url is shown in that format. eg: FileName.abc this is the actual scenario to specify extension of a jsf page, or is this an error.
I need to make some operations with a file. I struggle to understand why Apache is throwing this error:
(The system cannot find the file specified)
My file is located in the root directory of the project.
And here is how I indicate the path to it:
String filePath = "default.jpg";
InputStream inputStream = new FileInputStream(new File(filePath));
If I put the file in the Eclipse folder, it works... But I need it to work if I put it in my project's root folder.
recently I noticed that most of the Sun site pages have the extension .jspa, some even have .xml.So just curious about it because I don't know about jspa but as far as I know of xml, it is not rendered by browser like the way we see on Sun site.
View Replies View RelatedI want to programmatically change the default program which an extension is opened in. So .resantic extensions for example to run in my jar file when I double-click on it. I know i need a bat file or exe file because i can't directly run the jar file. But i was wondering if its possible to run it if its an executable jar file. Else i can just make a bat file that runs my program. Also how can i on double click send the path to the file that was clicked in the args[] array so i can open the actual file aswell instead of just opening the program?

I'm trying to find a specific file that already exists on the computer. I want to find that file and zip it. don't get sidetracked with whether or not the file exists, because I'm sure it does on my local machine and TDD will address that what-if scenario later.
My code and JUnit is below. Since its not finding the file, I assume I must be formatting 'path' wrong. I wonder if I'm even on the right track logically.
private ZipParameters zp = new ZipParameters();
private ZipFile zipFile;
public ZipFile createZipFile(File f, String path) throws ZipException{
zipFile = new ZipFile(path);

First of all, i am using ubuntu and jdk8. My problem: displaying the current path of a file in my system Approach: I have a file called dummy.txt in a given directory which have enough permissions and i did the following:
File file=new File("dummy.txt");
System.out.println(file.getAbsolutePath().substring(0,file.getAbsolutePath().lastIndexOf("/")));
I expected to see displayed the current path of the file without the name of the file but it is showing a different path. I just want to display the current path of the file without the name.
I am trying to figure out how to report the high and low scores with names from a file. The format is like:
