  • Referencing java resource files for cold fusion

    - by Chimeara
    I am using a .Jar file containing a .properties file in my CF code, however it seems unable to find the .properties file when run from CF. My java code is: String key =""; String value =""; try { File file = new File("src/test.properties"); FileInputStream fileInput = new FileInputStream(file); Properties properties = new Properties(); properties.load(fileInput); fileInput.close(); Enumeration enuKeys = properties.keys(); while (enuKeys.hasMoreElements()) { key = (String) enuKeys.nextElement(); value = properties.getProperty(key); //System.out.println(key + ": " + value); } } catch (FileNotFoundException e) { e.printStackTrace(); key ="error"; } catch (IOException e) { e.printStackTrace(); key ="error"; } return(key + ": " + value); I have my test.properties file in the project src folder, and make sure it is selected when compiling, when run from eclipse it gives the expected key and value, however when run from CF I get the caught errors. My CF code is simply: propTest = CreateObject("java","package.class"); testResults = propTest.main2(); Is there a special way to reference the .properties file so CF can access it, or do I need to include the file outside the .jar somewhere?

  • Need to have JProgress bar to measure progress when copying directories and files

    - by user1815823
    I have the below code to copy directories and files but not sure where to measure the progress. Can someone help as to where can I measure how much has been copied and show it in the JProgress bar public static void copy(File src, File dest) throws IOException{ if(src.isDirectory()){ if(!dest.exists()){ //checking whether destination directory exisits dest.mkdir(); System.out.println("Directory copied from " + src + " to " + dest); } String files[] = src.list(); for (String file : files) { File srcFile = new File(src, file); File destFile = new File(dest, file); copyFolder(srcFile,destFile); } }else{ InputStream in = new FileInputStream(src); OutputStream out = new FileOutputStream(dest); byte[] buffer = new byte[1024]; int length; while ((length = in.read(buffer)) > 0){ out.write(buffer, 0, length); } in.close(); out.close(); System.out.println("File copied from " + src + " to " + dest); }

  • C struct print, decode this code?

    - by pauliwago
    I am in the process of studying for a test, and I'm trying to work through some practice problems. I've been working on this a while now..but can't figure it out. Please take a look at the code fragment: union { int i; short x; unsigned short u; float f; } testout; testout.i=0xC0208000; Before I ask the question, can someone please explain to me how the above code works?? My guess is that testout.i=0xC0208000 puts either an int, short, unsigned short, or float and puts the result in that address. (?) The question is what prints out if we write printf("%d", testout.x)? I know we should expect digits....but I have no idea where they are getting the digits from....there is no output. Any explanation would be greatly appreciated. Thanks!

  • [Python] How to create a named temporary file in memory?

    - by conradlee
    I would like to use Python's tempfile module to create a temporary file that I will use for communication between processes (use of pipes is awkward). The documentation I've linked to above shows two functions that almost do what I want: tempfile.NamedTemporaryFile # For creating named tempfiles tempfile.SpooledTemporaryFile # For creating tempfiles in memory but actually I want a tempfile that is both named AND in memory. Any ideas?

  • How to print all rows in one page with Crystal Reports

    - by Matt
    I am using Crystal Reports 2011. I am totally new to crystal reports and reporting tools in general. I just added my data fields to the details section, but instead of showing all the rows in one page, a new page is created for each row. I did not use any grouping or change the section paging settings. This only happens for a blank report, when using the report wizard it works fine, but I can't see the difference between what I did and what the report wizard did.

  • Beginner servlet question: accessing files in a .war, which path?

    - by Navigateur
    When a third-party library I'm using tries to access a file, I'm getting "Error opening ... file ... (No such file or directory)" even though I KNOW the file is in the WAR. I've tried both packaged (.war) and "exploded" (directory) deployment, and the file is definitely there. I've tried setting full permissions on it too. It's on Unix (Ubuntu). File is war/dict/index.sense and the error is "dict/index.sense (No such file or directory)". It works fine on my Windows computer when running in hosted mode as a GWT app from Eclipse, just not when I transfer it to the Unix machine for deployment. My question is: has anybody experienced this before and/or are there differences in relative path that I should consider i.e. what's the root path for relative file access in a war?

  • Can I use php's fwrite with 644 file permissions?

    - by filip
    I am trying to set up automated .htaccess updating. This clearly needs to be as secure as possible, however right now the best I can do file permission-wise is 666. What can I do to setup either my server or php code so that my script's fwrite() command will work with 644 or better? For instance is there a way to set my script(s) to run as owner?

  • Why can't I reserve 1,000,000,000 in my vector ?

    - by vipersnake005
    When I type in the foll. code, I get the output as 1073741823. #include <iostream> #include <vector> using namespace std; int main() { vector <int> v; cout<<v.max_size(); return 0; } However when I try to resize the vector to 1,000,000,000, by v.resize(1000000000); the program stops executing. How can I enable the program to allocate the required memory, when it seems that it should be able to? I am using MinGW in Windows 7. I have 2 GB RAM. Should it not be possible? In case it is not possible, can't I declare it as an array of integers and get away? BUt even that doesn't work. Another thing is that, suppose I would use a file(which can easily handle so much data ). How can I let it read and write and the same time. Using fstream file("file.txt', ios::out | ios::in ); doesn't create a file, in the first place. But supposing the file exists, I am unable to use to do reading and writing simultaneously. WHat I mean is this : Let the contents of the file be 111111 Then if I run : - #include <fstream> #include <iostream> using namespace std; int main() { fstream file("file.txt",ios:in|ios::out); char x; while( file>>x) { file<<'0'; } return 0; } Shouldn't the file's contents now be 101010 ? Read one character and then overwrite the next one with 0 ? Or incase the entire contents were read at once into some buffer, should there not be atleast one 0 in the file ? 1111110 ? But the contents remain unaltered. Please explain. Thank you.

  • Strange python error

  • Can Adobe AIR Desktop application take full screen snapshots (aka Print Screen button)

    - by tzador
    I would like to know if its possible to get full screen snapshots from an air application. What i am interested in, is functionality similar to PrintScreen button in windows, which takes snapshots of all screens, including third party application windows, not just window in which air app is running. If its not specific to air, and flash/flex API can provide such functionality, it also would be great. Thanx a lot in advance.

  • how to get the PageFormat from a Java.awt.print.PrinterJob

    - by Alex
    Hi, I'm trying to use the PageFormat information to modify my javax.swing based printout prior to printing it. I am stumped as to how I can get the PageFormat from the PrintJob (which is obtained using getPrinterJob() and printDialog()). I know there is the getPageFormat method, but I can't figure out how to get the PrintRequestAttributeSet (which is not the printJob.getPrintService().getPrintAttributes()). Honestly, all I really want to know is the width and height of the page. Any ideas on how I can do that? Thanks.
