Problem with writing into txt file on the Web
Hello friends - please could you give me an advice? Java console says:
Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.io.FilePermission http:\web.telecom.cz\jiriczech\xanado.txt write)
Thank you a lot in advance:)!!
The place you are trying to write the file to does not have write permission.

Problem when I upload txt files to the server
Hi, I have a problem when I try to upload files to the server, and I can't understand the fail.
My case is:
I have a jsp page where a from is.
This form is sended to a servlet that proccess its content and upload the attach file to the server.
It works correctly (it uploads the files, txt, xls and csv), the problem is when I try to upload a txt file like this, for example:
Depth Age
0 0,1
2 0,9
3 2
5 6
6 9
8 12
34 25
56 39
101 40When I verify the uploaded file, this one has a character extra of return of line (a small square). This character prevents me from working then correctly with the file, on having detected a column of more.
Which can be the problem?
The code I use to uploaded the file is:
try
MyConnection Objconnection = new MyConnection();
boolean isMultipart = FileUpload.isMultipartContent(req);
// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Set overall request size constraint
upload.setSizeMax(1024*512); //524288 Bytes (512 KB)
// Parse the request
List items = upload.parseRequest(req);
// Process the uploaded items
Iterator iter = items.iterator();
String dat = new String();
String typeFile = new String();
while (iter.hasNext())
FileItem item = (FileItem) iter.next();
if (item.getFieldName().equals("typeFile") )
typeFile = item.getString();
if (!item.isFormField())
String fieldName = item.getFieldName();
String fileName = item.getName();
String contentType = item.getContentType();
boolean isInMemory = item.isInMemory();
long sizeInBytes = item.getSize();
int numbers=0;
for(int i=fileName.length();(i=fileName.lastIndexOf('\\',i-1))>=0;)
numbers++;
String stringFile[] = fileName.split("\\\\");
HttpSession session = req.getSession(true);
String loginSesion = (String)session.getAttribute("UserLogin");
String newUserFolder = loginSesion;
File createFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/"+newUserFolder);
if ("AgeModel".equals(typeFile))
createFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/AgeModels/"+newUserFolder);
if (!createFile.exists())
createFile.mkdir();
fileName = stringFile[numbers];
File uploadedFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/"+newUserFolder+"/"+fileName);
if ("AgeModel".equals(typeFile) )
uploadedFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/AgeModels/"+newUserFolder+"/"+fileName);
existe = Objconnection.existFile(fileName, typeFile, loginSesion);
if ( true == existe )
exito = false;
else
item.write(uploadedFile);
....// NOW REGISTER THE FILE IN TH DATA BASE
} // if (!item.isFormField())
} // WHILE ( iter.hasNext() )
catch(Exception e) {
out.println("Error de Aplicaci�n " + e.getMessage());
return exito;
...THANKSHi,
Sorry I am aware this question was posted way back, but I am having similar problem and haven't been able to find the fix yet.
So please let me known if you have got any ideas.
My problem is same that I have to upload a CSV file from Client Machine (Windows) to Unix Application Server.
I am using JSP method post and multipart/form-data (as in http://www.roseindia.net/jsp/file_upload/Sinle_upload.xhtml.shtml).
The file is uploaded fine but the problem is it displays carraige Return (^M) a square boxes on Unix file.
I can't ask user to convert file to Unox format before uploading. They just convert excel file to CSV and upload.
Is there any way I can get rid of these characters as I have to use this file further.
Sorry, I can't use any paid utility or tool for it.
I would appreciate if you could please help.
Thanks,

Problem with creating a new file in the Filter
hi,
i have the following problem.
1) For all requests ending with *.xml (for example requests such as http://www.asdf.com/feeds/myfile.xml ) i have mapped it to a filter
2 ) In the filter i did the following...................
//getting the file name from the url
//create the file if it does not exists..................
chain(request,reponse);
//done
problem is
3) a) For files which iam not creating in filter (i.e files which are already there) the response is proper it is returning a xml file
b) But for files which are not there already , which we are creating in the filter dynamically it is showing a 404 (i.e file not found message)
But if i refresh again in the browser it is getting a valid XML file.......................................
I could not able to figure it out why it is returning 404 error in cases where the file is being created dynamically.................................
Can any one guide me resolving this problem?Hi pawan
Try this badi : MB_MIGO_BADI -
(BAdI in MIGO for External Detail Subscreens) as the name suggest ,
If you want to add a screen in header level use : Method : PBO_header an code as :
e_cprog = 'ZMMPRM0001'. """ Your screen created
e_dynnr = '1000'. "Your screen No
e_heading = 'TEXT ID '(004). """" Name of the screen to be created .
ELSE .
e_cprog = 'ZMMPRM0001'.
e_dynnr = '1000'. "External fields: Display
e_heading = 'TEXT ID '."(004).
or if at item level
u can use methid : PBO_DETAIL
for item level screen creation . and code in the same maaner ..
You can explore the remaning methods as per your requirements .
Hope it helps ..!

Problems with plain text (.txt) files
I recently needed some tech. info to be loaded on my PlayBook (OS2.1), but I found that I could not open the files when on location. I had downloaded PlainTextEdit and several others, and have Ghost Commander file manager (which claims to be able to open text files, but none of the apps could find the files - they seem to be searching a different location from that used by the built in File Manager app - which sees the files, but can't locate a program to open them (I had transferred the files both from my Mac desktop and through DropBox).
Does anyone know why this is happening?
I have since taken to putting files on as PDF's, which works fine, but I'm still concerned that there are apps on my Playbook that are searching unknown locations.
Solved!
Go to Solution.Air Browser showed me the Android files that the other apps were searching - I can now move my files into that location.
can you tell us the folder location for each of those two apps ?
Maybe it would be nice if it was displayed in the help section of each of those two apps?
Do you think you will contact those two developers ?
Hi Xandrex,
What I see in AirBrowser is the normal file structure as shown by the built in file manager app, PLUS a directory called Miscelaneius, which contains a directory called 'Android', which is what the other apps (I assume they are both Android ports) search - they don't seem to be able to see the regular Playbook file structure.
Using AirDrop as you suggested, I am able to copy my files into this Android file structue, and work on them.
It would be very nice if Android ports could read the correct file structure, or at least warn users in advance, but as I am not likely to need any more apps, I won't bother to contact the developers about correcting this - even if they can, given the BB OS's emphasis on security.
Thanks again for your help,

Problems with PSE 10 when saving for the web.
I'm having problems saving for web with PSE 10. I edit in RAW, edit in PSE 10, save as Jpeg, resize and save for the web. Results are muddled and not sharp (looks cartoonish). Also, there is no metadata when you look at the image properties. I uninstalled the program and installed again. No change.
Are you resizing the photo before save for web?
What settings are you using in the save for web dialog for the jpeg quality?
If you compress the jpeg too much (low quality settings below 60), that can make your photos look bad.
And save for the web in pse 10 automatically strips any metadata in order to keep the file sizes smaller.
Also, the save for web in pse 10 has a bad habit of not remembering your last used settings, so it's good to verify that your actually set to jpeg instead of the default GIF setting.

Problems with running reports having parameters, on the web
Dear all,
I have recently installed Oracle 9iAS v1.0.2.2.1 on Suse linux 7.3. Also, installed
Forms and Reports 6i alongwith it.
Building and running reports both static and ones that accept parameters was a breeze.
I could also run reports from the web successfully until now when I am trying to run a
report that accepts parameters.
When I enter the following URL:
http://<webserver>/cgi-bin/rwcgi60?report=<some.rdf >userid=<user/passwd@db>
server=<reportservername>destype=cachedesformat=html+paramform=yes
This is what happens:
1. I am prompted for a parameter value in the html format
2. On entering a suitable value, I am prompted for information to connect to the
database viz. username, password and database name
3. Entering suitable values for the above results in a hung state. There is no output and
the busy signal is all that I get for a long long time.
4. Also, stopping this session results in other such sessions resulting in a hung state, too.
That is to say, if I had run a report throug the web successfully before trying this
one, after aborting this session, I cannot re-run the previous successful report. That
too results in a hung state. I have to restart the reports server rwmts60 once again
as well as the web server for things to work smoothly.
I tried recreating the cgi env and ran a strace on the rwcgi60 command. It produces
an error saying 'libzrc60.so.0: no such file or directory' where as it is very much
present in the default LD_LIBRARY_PATH. This could be misleading as I am not sure
how I correct I was in re-creating the CGI env.
This is a problem I face only when I enter the "paramform=yes" option in the URL.
Also, excuse me for my ignorance , but I have no idea how to interpret the cgicmd.dat file.
It does mention that %P, %PT, %PC are amongst the currently recognised special
parameters, though.
Will someone please help me out asap as this is quite urgent.
Thanks a million in advance
HemaHi Hema,
There could be various things that explain this, but from your symptoms it looks like the engine is hung processing this report. This could be as simple as a PL/SQL trigger that is in an infinite loop. Anyway, a simple thing to do is to add TRACEFILE=filename&TRACEMODE=append&TRACEOPTS=TRACE_ALL onto your URL. This will create the specified file and dump information into it about what Reports is doing as it is processing your report. If it is hung in an infinite loop, you should be able to see how far it got when you kill it.
Also, you can see the status of the reports job queue by using the http://.../rwcgi60?showjobs command. If the report is executing forever, you'll see it sitting there in the job queue.
regards,

Hej!
I've switched from Google to Firefox because I was so tired of Google crashed all the time. Now I have the same problem with Firefox, Bank id, file downloading, accessing Web pages, none of it works. What is the error?
Ronnie.When Firefox crashes, it usually records information about what was happening at that moment and displays the Mozilla Crash Reporter. Are you seeing that, or is Firefox just freezing and you're killing it?
Assuming you have crashes, you can submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the support article "[[Firefox Crashes]]" (especially the last section) for steps to get those crash report IDs, and then post some of the recent ones here.
If that's not possible, have you tried Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference? -
I have a small LabVIEW program which writes random numbers very fast into a ASCII-file. I want that file to be copied to a new position every 10 min. Therefor I use a backup/synchronisation software which is doing a copy operation every 10 min. It works fine a certian amount of time and after a while I get either an LabVIEW error (LabVIEW: Fiel already open: NI-488 Comand requieres GPIB Controller to be System controller) or an backup-software error (couldn´t open file...whatever). I´m guessing, it has something to do with file-access but I don´t know why?!? If I run the LabVIEW program and I copy and paste the random-number-file with the windows explorer very fast (pressing ctrl+v rapidly) while LabVIEW is still writing into this file, no error appears. Can sombody help me?
LabVIEW 2011Hi Serdj,
you don't get a GPIB error, the error number has just 2 different explanations...
Well, you have two programs accessing the same file. One program just wants to make a copy, the other (LabView) is trying to write to the file. When copying a file that is written to you get inconsistent results! That's why one of both programs is complaining an error...
You can't have write and read access at the same time! (But you can have more than one read access at the same time...)

Now that code above produces two errors. First of all.
local trim();produces the error:
Syntax error, insert "AssignmentOperator ArrayInitializer" to complete ArrayInitializerAssignementSecondly, if I take that into comments, the line
setLabel(m.get(LineField.getText()));Produces the error:
The method setLabel(String) in the type Personnel is not applicable for the arguments (Object)If anybody could help me solve these, I would be sincerely thankfull.
Now, before anybody asks as to why I want to trim the String in the first place, it is due to the fact that I compare it to another String that is without whitespaces. Thus the field that DOES have whitespaces was preventing me from launching into the if loop:
if (sortHelp[1]==local) {
flag=true;
(within actionperformed) Or at least that's my explanation as to why the loop never launched. If it is wrong, can somebody please explain?)
I apologize for the horrible indentation and lack of comments. This is an unfinished version.. I'll be adding the comments last (won't that be a joy), as well as looking for things to cut down on and make the program more efficient.
Anyways,
Thanks in Advance,

Java.io.NotSerializableException when overwrite the JTable data into .txt file
hi everyone
this is my first time to get help from sun forums
i had java.io.NotSerializableException: java.lang.reflect.Constructor error when overwrite the JTable data into .txt file.
At the beginning, the code will be generate successfully and the jtable will be showing out with the data that been save in the studio1.txt previously,
but after i edit the data at the JTable, and when i trying to click the save button, the error had been showing out and i cannot succeed to save the JTable with the latest data.
After this error, the code can't be run again and i had to copy the studio1.txt again to let the code run 1 more time.
I hope i can get any solution at here and this will be very useful for me.
the following is my code...some of it i create it with the GUI netbean
but i dunno how to attach my .txt file with this forum
did anyone need the .txt file?
this is the code that suspect maybe some error here
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String filename = "studio1.txt";
try {
FileOutputStream fos = new FileOutputStream(new File(filename));
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(jTable2);
oos.close();
catch(IOException e) {
System.out.println("Problem creating table file: " + e);
return;
System.out.println("JTable correctly saved to file " + filename);
}the full code will be at the next msgthis is the part 1 of the code
this is the full code...i had /*....*/ some of it to make it easier for reading

A problem with importing layered PSD file into Flash
Hi.
There's a problem with importing layered PSD file into Flash.
If I import a layered PSD file, some part the color of the lower layer is shown at the edge of objects or shadows. Instead, if I crop each layers first and import them, there's no problem.
If the higher layer has brush or transparent effects, it becomes worse.
Any help with this problem?
Thanks.How was the original art created? Was the original RGB or CMYK? What is the resolution of the Photoshop file? Flash only works well with RGB and 72 pixel per inch resolution. If your original art is not set this way, then Flash will attempt to convert it as it imports it. Flash uses the sRGB color space. You'll get the best color translation if your Photoshop file is using this color preference.

I have a problem with running an EXE file on win2000, the Lab View is 5.1 and I do not know if it is 16 bit...what should I do?
Hi Arika,
The drivers that you need to install to make your executable work depends on what your executable is doing. To get started, you need to have the LabVIEW Run-Time Engine installed on your target machine (the Win2000 machine you are planning to use) in order to run your executable. Next, you need to determine what drivers your executable uses, if any. For example, if you are using GPIB instrument control, you will need to install the NI-488 drivers on your target machine. If you are performing data acquisition, you will need to install NI-DAQ drivers. If you are doing image acquistion, you will need to install NI-IMAQ drivers.
All these drivers are available for downloading on ni.com. To get the drivers, go to ht
tp://www.ni.com/support , click on the link that takes you to Drivers and Updates (under Option 3), and click on the links to get to the driver(s) you need. For example, if you need the LabVIEW 5.1.1 Run-Time engine, click on the All Drivers and Updates by Application link on the main page (http://www.ni.com/softlib.nsf/). Then click on the LabVIEW link, Windows 2000, Run Time Engine, and then you will see the link to get to the page to download the LabVIEW 5.1.1 Run-Time Engine.
I hope this information helps.
Best Regards,
