How to find out the format of a file?
Is there any way to find out the format of a file?
By format I mean binary, text, .doc, .rtf, etc. Please kindly help
The unix file command:
file *
foo.doc ms-office file / word
bar.png png image, 32x32 pixels, no transparency
moo.hhml html text
note that as in the last - file names are ignored, it works by checking the beginning of each file's data against it's database, and as in #2 it can sometimes see a lot more than just the file format.
Don't know of a windows port, you could try cygwin

How to find out the status of a file in java
Hi
I have an application that writes xml files anytime it is invoked. I am writing all unique files to a windows directory.
i also have an ftp client working on that directory that scans all the files and sends them to the server every few minutes.
I want to find a way using which all the files except the one that is being currently written by the application are transferred.
Is there a way to find out in java as to what file is being written to by the operating system at that point of time ? I have looked around for quite a long time and have not been able to find a solution to this problem.
Any help will be deeply appreciated.out = new FileOutputStream(matcher.group(1)+".open" , true);
FileChannel ch = out.getChannel();
FileLock lock = ch.lock(0L, Long.MAX_VALUE, false);
// Connect print stream to the output stream
p = new PrintStream( out );
p.println ("\n" + parms.getProperty( value ) + "\n");
p.flush();
p.close();
lock.release();Ok, I tried implementing locks but I dont know why it is not working...An exception is thrown and nothing is wriiten to the file. I have employed a complete lock on the file so that no other JVM application can use it.
Actually this is a server that grabs data sent from an Iframe and writes it down to a temp file. I open a file input stream, lock it and then use a printwriter strream to write the realyed data to the file. Any inputs as to what is wrong with the code snippet above????? -
How to find out the size of a file?
Hi,
I would like to determine the size of a file from my code. How is that possible? I do not find any appropriate method in the java.io.File class.
Any help would be very appreciated!java.io.File.length()
Returns the size of the file as a long. The number corresponds to the number of bytes in the file. -

Thanks in advance?It depends on the file.
Sometimes it is possible by analysing the file contents. Other times you have to know a priori.

How to find out the locale setting in a browser?
In my Java web project, the multi-lingual issue on the JSP pages is handled by JSTL. It works fine so far for any input messages. However, some messages come from the container. It is needed to find out the browser's country and language settings inside of the container. My question is how to find out the settings?
Thanks in advance.
v.Hi, this I found on James' website--see http://www.rf.net/~james/perli18n.html#Q28
Q28. Can web servers automatically detect the language of the browser and display the correct localized page?
A28. Yes. HTTP/1.1 defines the details of how content negotiation works, including language content.
WWW browsers send an Accept-Language request header specifying which languages are preferred for responses. This technique works fairly well, although some versions of Netscape Navigator send an improperly formatted request parameter. Also, switching language preferences in either Navigator or IE 4 doesn't always "take" without first deleting a language hint.
Few sites do content-negotiation on language, and interestingly enough I do not know of any major portals doing this. One site that does is Sun's documentation library at SunDocs. Debian.org does a very nice job of using Apache content negotiation wih languages and also has some nice help info too on Setting the Default Language.
Apache's Content Negotiation features will select the right page to return, whether HTML or image file. Annoyingly, the match logic is very literal, so a browser request for en-us will not match a server entry of en except as a last resort. Any other exact match will win over en, even if en-us was first preference.
There are 2 ways of doing content negotiation with Apache: type or variant maps and multiviews.
Variant Maps
In httpd.conf, disable Options Multiviews if configured and add
AddType type-var var
DirectoryIndex index.var
Then create an index.var file like this:
URI: start; vary="type,language"
URI: index.html.en
Content-type: text/html
Content-language: en-GB
URI: index.html.en
Content-type: text/html
Content-language: en-US
URI: index.html.en
Content-type: text/html
Content-language: en
URI: index.html.fr
Content-type: text/html
Content-language: fr-CA
URI: index.html.fr
Content-type: text/html
Content-language: fr
URI: index.html.es
Content-type: text/html
Content-language: es
Multiviews
The multiviews technique works like this. This does add extra server load, as each content directory must be scanned for the variant document names.
index.html is localized into variant documents such as:
index.html.en (or index.en.html)
index.html.fr
index.html.es
index.html (or index.html.html as a reader has recommended) symlinked to one of the above as the last resort.
Here's an example of http.conf directives for this:
# in httpd.conf
AddLanguage en .en
AddLanguage fr .fr
AddLanguage es .es
# LanguagePriority allows you to give precedence to some languages
# in case of a tie during content negotiation.
# Just list the languages in decreasing order of preference.
LanguagePriority en es fr de pt
Options Multiviews
# end of httpd.conf fragment
Starting in Apache 1.2, you may also create documents with multiple language extensions.

How to find out the password of system?
Dear all,
I would like to know how to find out the password of system as I forgot it?
Thanks a lot
Francis SZESince oracle passwords are encrypted so you cant see actual password. But you can use following procedure to login to oracle with system user.
For any account issue this statement.
select username,password from dba_users where username='SYSTEM';
EMDU27ANS729273
this will give you the password in encrypted format.
Now you can change that password for temporary purpose.
alter user system identified by test;
Now login and do your work.
After login you can issue this statement to reset the password to its original value.
Alter user system identified by values 'EMDU27ANS729273';
You have to enter the same encrypted password in the quoted string which you had found in 1st statement.
Cheers. -
