Applet writing on a output file
I am new to JAVA and I've got jdk 1.4.1 downloaded.
I am thinking it is possible to have a JAVA applet
which writes on a output file.
In order to do that, I tried to use the code below, where the Applet "write.class" should display a string on a painted area and write to file "myfile.txt".
Now compilation is OK (no error or warning messages), and I tried to incorporate this Applet into a HTML code (by using the sintax <applet code="write.class" width=200 height=50> </applet>).
When I open the HTML document using Internet Explorer the Applet is run, but the file "myfile.txt" is not created.
Can somebody explain me what is going wrong?
Any suggestion or comment is welcome and appreciated.
import java.applet.Applet;
import java.awt.*;
import java.io.*;
public class write extends Applet {
public void paint(Graphics g) {
g.drawString("The Java Applet is Writing!",20,30);
main();
public static void main(){
FileOutputStream out;
PrintStream p;
try
out = new FileOutputStream("myfile.txt");
p = new PrintStream( out );
p.println ("This is to be written to a file");
p.close();
catch (Exception e)
System.err.println ("Error writing to file");
applets are not allowed to write to the local file system.

Hello all,
I have an ABAP program in BW which reads the data from a BW ODS active table and writes the output to an external file on the server.
The file that is generated is huge(13 MB). The file is generated with the correct results, but along with the data, the program header(filename, path, etc) is also written to the output file which is undesirable. The header is written for every few hundred pages. I want to avoid this.
Database is Oracle.
The syntax for the file declaration is..
PARAMETERS: fileout(120) type c lower case default 'xxxx.csv'
obligatory.
and the open statement is as follows....
OPEN DATASET fileout FOR OUTPUT IN TEXT MODE ENCODING DEFUALT.
In the above statement I want to try taking out the "ENCODING DEFAULT" clause, but it says "in TEXT MODE the ENCODING must be added". I have seen other programs which are already there without that clause.
Any suggestions will greatly appreciated. Thanks.

Powershell scripts not writing it to output file
Hi,
Below is my script which loops through all sites and web in a site collection and if the particular web part is added in a page, it will give the page URL and it should be written to a output file.
function enumerateWebParts($Url)
$webApp = Get-SPWebApplication $Url #Get WebApplication URL
foreach($web in $webApp | Get-SPSite -Limit All | Get-SPWeb -Limit All) #foreach loop to iterate through all sites and webs of WebApplication
if ([Microsoft.SharePoint.Publishing.PublishingWeb]::IsPublishingWeb($web)) #Check if site is a publishing site
$pWeb = [Microsoft.SharePoint.Publishing.PublishingWeb]::GetPublishingWeb($web)
$pages = $pWeb.PagesList
foreach ($item in $pages.Items)
$fileUrl = $webUrl + "/" + $item.File.Url
$manager = $item.file.GetLimitedWebPartManager([System.Web.UI.WebControls.Webparts.PersonalizationScope]::Shared);
$wps = $manager.webparts
foreach ($type in $wps) #loop through each type found $wps
#Write-Host " type searching";
Write-Host $type.GetType().Name;
if ($type.GetType().Name -eq "RightMenu") #if webpart $type -like KWizCom select webpart object
Write-Host "found";
$wps | select-object @{Expression={$pWeb.Url};Label="Web URL"},@{Expression={$fileUrl};Label="Page URL"},DisplayTitle, IsVisible, @{Expression={$type};Label="Type"}
Write-Host $fileUrl;
$page=$pweb.Url+$fileUrl;
Write-Output $page;
else #if web is not a publishing site
$pages = $null
$pages = $web.Lists["Site Pages"]
if ($pages)
foreach ($item in $pages.Items)
$fileUrl = $webUrl + "/" + $item.File.Url
$manager = $item.file.GetLimitedWebPartManager([System.Web.UI.WebControls.Webparts.PersonalizationScope]::Shared);
$wps = $manager.webparts
foreach ($type in $wps)

Write-Output $page;
else
# Write-Host “… completed processing” $web
$row = enumerateWebParts(‘http://sptest.danfoss.net’) #call the enumerateWebParts function pass it the URL for the web application
I run the command through D:\RightMenu.ps1 | Out-File D:\RightMenu.txt

http://stackoverflow.com/questions/10340007/exporting-powershell-output-to-text-file
You can always redirect the output an exe to a file like so (even from cmd.exe):
powershell c:\test.ps1 > c:\test.log
Within PowerShell, you can also redirect individual commands to file
but in those cases you probably want to append to the log file rather
than overwrite it e.g.:
$logFile = 'c:\temp\test.log'
"Executing script $($MyInvocation.MyCommand.Path)" > $logFile
foreach ($proc in Get-Process) {
$proc.Name >> $logFile
"Another log message here" >> $logFile

Reports 2.5 over-writing an existing output file
When I try to save the Reports 2.5 output to a file that already exists, the application seems to work. However, the Report Server logs indicate an error - Rep 1081 - Unable to open file ...
When you check if the file was created, its even worse that the original file has already been deleted - (puff! ... gone).
Am on NT4.0 as client, could this be an NT bug or am just missing something on my code?
Hints and suggestions please.
nullI really appreciate your help, but I already changed the configuration to open a file path taking another ActiveX example as a reference. Here is my subVI's I used, but they are merged in LLB. I am sorry for my ignorance of how to extract all the subVI's from this file.

Output file from an applet to a server
Hi,
I am trying to find a way to get my applet to create an output file on the server in the directory of the applet .class file. This seems to be a problem since most classes I have tried seem to write the ouput file to the computer which is running an instance of the applet as opposed to the server which is running the applet code. If anyone knows of a library or class that can create and write to an output file on the server in the directory of the applet .class, please let me know. Thanks.

hi there.
i need serious help on using an applet and writing the user response into a text file.
issit possible in the first place? cos i read at a lot of sources saying applet cant write to file?
any help is much appreciated
thx!Where do you plane on writing the file to server where the applet is or on the client machine? Applets can only write to files that are on the same filesystem or on the same machine that it was loaded into the browser from. So if you want user to run this applet and have it write out a file you will have to get them to download the .class file and then run it from their computer.
here is somthing might help a bit more.
http://java.sun.com/sfaq/#read
Please give more detail about what you want to. -
What are the cases that cause the I/O error writing to output file
may i ask what are the cases that cause the I/O error writing to output file ??
cause i have the write path and the input file has data
any ideas???and the permission is to write first time then append to itBy "permission" is meant the operating system controlled rights that let
particular users do specified things with specified files or directories.
the error message is a the title of the message
I/O error writing to output fileThe java runtime actually creates a much more useful error message than
this but, unfortunately, your program is swallowing this error message and
replacing it with the message you see.
Somewhere in your code you have something like:try {
// all sorts of stuff goes here
// including the code that is intended to
// write to the file
} catch(IOException ioe) {
System.out.println("I/O error writing to output file");
// add this line
//ioe.printStackTrace();
}It might say Exception rather than IOException.
To get a much more useful error message add the commented line. -

I didn't do a complete inspection of your code (because it's too much and unreadable as it is) and I don't know POI, but creating a new HSSFWorkbook for each input file sounds fishy to me ... try re-using the workbook and just creating a new sheet in each iteration. -

Sorry about the long lines.
As you can see, all input files saved in array called files, however when OpenFile1() function is called, it take input (fileName_in) as a single file not an array. I'm assuming this causes the exception.
When there's muptiple inputs, program should take each file from getFileName() to outputToFile() sequentially.
Does anybody have an idea to solve this?
Thanks a lot!!you naming convention is confussing. you should follows Java naming convention..you have a getXXX but decalred the return type as "void"...get usully means to return something...
your code is doing too much..and hard to follows..
1. get the selected files
for each selected file
process the file and return the result
write out the result.
/** close the precious resource */
public void closeResource(Reader in){
if (in != null){
try{ in.close(); }
catch (Exception e){}
/** get the total number of line in a file */
public int getLineCount(File file) throws IOException{
BufferedReader in = null;
int lineCount = 0;
try{
in = new BufferedReader(new FileReader(file));
while ((in.readLine() != null)
lineCount++;
return lineCount;
finally{ closeResource (in); }
/** read the file */
public void processFile(File inFile, File outFile) throws IOException{
BufferedReader in = null;
StringBuffer result = new StringBuffer();
try{
in = new BufferedReader(new FileReader(inFile));
String line = null;
while ((in.readLine() != null){
.. do something with the line
result.append(....);
writeToFile(outFile, result.toString());
finally{ closeResource (in); }
public void writeToFile(File outFile, String result) throws IOException{
PrintWriter out = null;
try{
out = new PrintWriter(new FileWriter(outFile, true)); // true for appending to the end of the file
out.println(result);
finally{ if (out != null){ try{ out.close(); } catch (Exception e){} } }

File Adapter Overwriting the output files
Hi All,
I´m using a File Receiver Adapter to write flat files on to an FTP. Same Communication Channel is used for all types of output files (As per the business requirement the file name(
MzOutput.txt) shud b same for Deliverz orders, Purchase orders etc...). The receiver legacz szstem reads one file at atime and deletes it. So if i´m writing a Deliverz Order File, i have to wait until the file MzOutput.txt gets deleted and then i have to write the next file using the same name. in order to acheive this, i had used a module processor which waits until that MzOutput.txt gets deleted. Mz problem is
As there are ´n´ no of orders waiting in the queue, if at 12:14:00 the MzOutput.txt gets deleted, then two threads which check for the existance of the MzOutput.txt file finds nothing and tries to write at same time. as a result, first file got overwritten by the second file.
I dint check the indicator OverwriteExisting File in the CC configuration.If i use two different CC channels to write the same file, it is giving FTP Exception which is true.
I´m loosing few deliveries as a result of the above case. Can anzone please help me out in this regard?
Thnx in Advance
AnilHi Anil,
Why dont you write the files with 'Add time stamp' option on for the file name and then the third party/legacy system to read the files in the order which they were created.?
Another option will be to write these files into a folder with these Add time stamp option/counter option and make a shell script check the folder for the MzOutput.txt file exists in the folder from where the third party/legacy system reads the file and once it has deleted the existing file, then ur files shud be moved in the order in which they were written n the temporary folder.
This will avoid the queue of messages in the adapter engine.
Cheers

How to map expdp parallele process to output file
How to map expdp parallel process to its output file while running...
say i use expdp dumpfile=test_%U.dmp parallel=5 ..
Each parallele process writing to its related output file.. i want to know the mapping in run time...I'm not sure if this information is reported in the status command but it's worth a shot. You can get to the status command 2 ways:
if you are running a datapump job from a terminal window, then while it is running, type ctl-c and you will get the datapump prompt. Either IMPORT> or EXPORT>
IMPORT> status
If you type status, it will tell you a bunch of information about the job and then each process. It may have dumpfile information in there.
If you run it interactively, then you need to attach to the job. To do this, you need to know the job name. If you don't know, you can look at sys.dba_datapump_jobs if prived, or sys.user_datapump_jobs if not prived. You will see a job name and a schema name. Once you have that, you can:
expdp user/password attach=schema.job_name
This will bring you to the EXPORT>/iMPORT> prompt. Type status there.
Like I said, I'm not sure if file name information is specified, but it might be. If it is not there, then I don't know of any other way to get it.

Server/browser requirements for WebHelp output files
What are the UNIX server and browser requirements in order to
display a WebHelp project output file correctly?
When I generate the primary layout, I am not selecting 508
format, and I select Java Applet as the preferred method for the
Navigation Pane (checking the radio button for DHTML > Java
Applet > Pure HTML as the order of preference.
When viewing the help project on the UNIX server through
Mozilla, the page appears to load and reload, load and reload.
Sometims pressing Esc. stops it and you can view the TOC and
content pane. The way around this is to generate Pure HTML only,
but then the index and the glossary become very difficult to use.
Robohelp Webhelp descriptions claim to work on all platforms
and in all browser types. What requirement are we missing on our
UNIX server so the project can display correctly?
Thanks in advance for your time and trouble. :-)Hi GEWB,
Here are some more details--
Generate Webhelp output setup:
Use lowercase filenames (recomm. for UNIX)
Toolbar buttons: Content, Index, Search
Navigation: Add breadcrumbs links
Additional options: Enable Highlight Search results, Synchronize TOC automatically
Navigation Pane preferred format: DHTML > Java Applet > Pure HTML
Optimize speed for: Web site
Q: how are you setting up your Linux to open the default project page?
A: I use Linux only to launch the webehelp output.
Q: Are you opening the GENERATED project default page or trying to open the project source files?
A: I am trying to open the generated project default page. I copy the Webhelp folder to a Linux machine and launch the index.html page to see the output.
Q: Why are you replacing the foreward-backward slash?
A: In Linux '\' is not supported for hyperlinks/filepaths. Therefore I changed the backward slashes to forward slashes.
The scenario:
When the project files have filepath such as ../../doc/xyz/,
when I view in Windows (IE)- I can access the link
when I view in Linux (FF)- I see broken link with error message somewhat like "cannot find ..\..\doc\xyz\". (Note the changed usage of slash)
This indicates that the generated files changes the forward slash to backward.
Maybe you are looking for
