client machine is windows XP
public void init()

int succesbytes = 0;
int current_read;
byte[] strMsg11 = new byte[urlfl.getContentLength()];
int readrs;
BufferedOutputStream outfl =new BufferedOutputStream(new FileOutputStream("c:\\My.dll"));
while(inFile1.available() > 0)
current_read =inFile1.read(strMsg11,0,urlfl.getContentLength());
System.out.println(" Current Read = "+current_read);
succesbytes += current_read;
outfl.write(strMsg11,0,current_read);
msg.setText("<html>"+successbytes+" bytes downloaded successfully..<html>");
System.out.println("Written ... = " +succesbytes );
outfl.flush();

I am getting the following message "safari could not download the file (440MB) because there is not enough disk space. disk utility says i have 249.8 GB of available disk space. any suggestions as to what is the problem would be appreciated

i am getting the following message "safari could not download the file (440 MB) because there is not enough disk space. please delete files or download to another disk." when i check system information it tells me i have 249.82 GB of disk space available. any suggestions as to what i can do to resolve this problem.

don
thanks for your suggestion. that is the same advice that i got from the geek squad at the local apple store.
i did what he instructed but it did not work. i have since called apple support twice regarding the problem. they had me start the computer in safe mode, going into the library and deleting a phlist file (i think) do a repair disk permissions, do a repair disk, empty the cache, and finally the last guy told me to unplug the computer from the wall socket and restart.
when i mentioned the advice you and the apple store guy gave me they sort of poo pooed it saying that was done when they did all this other stuff.
i am now waiting for the download to be completed to see if unplugging the computer had any effect.
thanks again for your kindness in answering my concern.

Help! How do I download software for a HP Laserjet Professional P1100? I keep getting the same message when I have downloaded the file "Your security preferences allow installation of only apps from the Mac App Store and identified developers" Help!

How do I download software for a HP Laserjet Professional P1100? I keep getting the same message when I have downloaded the file "Your security preferences allow installation of only apps from the Mac App Store and identified developers" Help!

You can change the settings in Security & Privacy to "Anywhere"...
That should work... as to whether the printer driver will work, that's another question.
Good luck,

Can I leave the display open for say all day while downloading torrent file

Sometimes it takes all day to download a torrent file can i leave the display on or should i turn it off and will my macbook keep downloading the file thank you

It's fine to leave it on but you can also just set the display to go to sleep and let your computer keep working. The settings are under *System Preferences* in *Energy Saver*. I usually have mine turn off after 15 minutes so it will rest while my download or other work continues.

It shows a POP up window by which u can save or opens the file. But no pop up displayed in this case.
-Shreya

Hi,
Made the same changes but still getting the same error.
The earlier URL also that I had mentoned would dynamically make this url mentioned by you and then shows the pop up window.
However when I am right clicking on the download link and then clicking 'Save target as' then this error message is provided:
Internet Cannot download [schema name].download_myfile2 from [DNS name]
Internet Explorer was not able to open this Internet Site.The requested site is either unavailable or cannot be found .Please try again.
Please help..
Thanks in Advance ...

Display save as dialog when downloading a file

Hi,
I want to display a save as dialog when the user downloads a file.
Now I get a dialog where the user can choose to open or save it.
I set these headers:
res.setHeader("Content-disposition", "attachment; filename=" + filnamn);
res.addHeader("Content-Type", "application/force-download");Thanks!

Sorry!
When the user downloads a file I want to open a dialog where the user
can write a filename and then click Save to save the file.
Today I get a dialog where the user first have to choose if he wants to open or save the file.
When he clicks save then the dialog appears that I would want to be displayed.
I hope this clearifies my question.

Error while downloading a file

I have written a servlet that downloads a file from my server on to my mobile.
i have written the following code to download the file:
URL url = new URL(path);
                    URLConnection connection = url.openConnection();
                    InputStream stream = connection.getInputStream();
                    BufferedInputStream in = new BufferedInputStream(stream);
                    FileOutputStream fos = new FileOutputStream(fileName);
                    BufferedOutputStream out = new BufferedOutputStream(fos);
                    int i;
                    while ((i = in.read()) != -1)
                        //System.out.println("Reading the file");
                        out.write(i);
                    out.flush();The code has no errors, but i m unable to download the file. The mobile gives me an error saying:
Services: Empty File
Can anyone please help me out with this problem.
with regards,
Shirish

This way to download files from server looks odd. You're issuing a new URL connection, likely to self. This may be slower than accessing the file directly using FileInputStream.
But anyway, you haven't set the contenttype and contentlength accordingly. Likely the mobile is aborting the download immediately since the headers have sent a contentlength of 0 bytes.
Check at the bottom of http://balusc.xs4all.nl/srv/dev-jep-pdf.html for some downloadFile() snippets, which might provide useful insights how to download files.

Getting Exception in JWS while downloading jar files from server

Hi All,
I am running JWS on j2re1.4.2_10(build 03). while JWS is trying to download jar files from web server, I am getting the following Exception.
All the jar files are signed. Any idea ?

Are you able to download your *.jar files directly from server
For example say,
http://127.0.0.1:8080/test/testme.jarIf yes,
Then problem should be with your *.jnlp file. Check all your *.jar with respect to context location of your url from where you are downloading *.jnlp file

"\n" problem while downloading the file in unix environment

Hi folks,
I have some problem in uploading and downloading the file in unix environment..
This is my sample code i am using.
File userDataFile = new File("xyz".csv");
out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(userDataFile),"UNICODE"));
out.write("Name"+"\t");
out.write("Age"+"\t");
out.write("Dob"+"\t");
out.write("Contact"+"\n");
for(int i=0;i<retList.size;i++){
out.write("xyz"+"\t");
out.write("22"+"\t");
out.write("300399"+"\t");
out.write("xyzzz"+"\n");
as per this i wrote code for generating the reports. Its contains some 7k records.
Its works in Windows environment.
Some times in Windows environment if the contents size is 7000 records means
i got only the headers..
I am not getting any real records.
I am not sure.. my client is using may be an unix environment..
Please give the solutions for this..
Very thanks in advance.

Hi Jothi,
This is not an answer to your question. It is a question for you instead. I have tried to reach you on several forums regarding the HAP_DOCUMENT documentation you have.
Again, I am really sorry to contact you through a differente forum, but I really need the HAP_DOCUMENT documentation for my project.
Please send me a message to [email protected]
Thanks again.

Mozilla should always give open with option while downloading any file

in Mozilla, when i click on the file to download the dialog box comes with the options of either opening it or saving it. say i get open with option when i click it, if i toggle to save it and go ahead with that process. Mozilla is remembering the last event, and showing me save it option selected when i click on download that file. i would want to set the mozilla config to have open with option selected for any kind of download in my browser. how to do this?

yes this is a way to keep giving me "open with" option for that type of the file. but still if user clicks save option. next time it will show save option clicked while downloading. am not sure if i have put the query correctly. is the problem statement clear?
the reason i want this is because my script which is automated script for an application, when download is clicked i want the open option to be enabled so that i just do a key down option. if it is going to be different everytime. i cant use this script.

Inserting Field Names as Header while downloading the file

But it goes to dump at       l_descr_ref ?= cl_abap_typedescr=>describe_by_data( gt_fldname ) where I am trying to make the filed names horizontal.
Can anyone help on this?

The issue has been resolved after writting:
      l_ref_table ?= cl_abap_tabledescr=>describe_by_data( gt_fldname ).
      l_descr_ref ?= l_ref_table->get_table_line_type( ).
Thanks.
