Create xml file and write data in to it:

Hi All,
I have a small requirement here.....
I have a java program which reads a xml file.
Now i have stored the contents of that file in to a java object.
I want a sample code now which would take theabove mentioned java object as an input ,create a xml file and write these entries in to the file.
Can anyone help me in this?
Your help would be appreciated.
Thanks in advance.

Hmmm. There is nothing special about an XML file to any other file. The data is simply formatted in a certain way. So to write an XML file, it is no different to writing any other form of file in Java (assuming you know the structure of the xml format to write - which you should)
If you don't know how to write files using Java I would suggest using the Java Tutorial found on java.sun.com and do some reading up about I/O since this is fairly fundamental.

How can FMS create a text file and write data into it in the Server application folders?

Recently, I writed a programe about creating a text file and writing data into it in the server application folder. My code is as following:
           var fileObj = new File("/MyApp/test.txt");
           if( fileObj != null)
                  if(fileObj.open( "text", "append"))
                        fileObj.write( "                                                      ———— Chat Info Backup ————\r\n" );
                        fileObj.close( );
                        trace("Chat info backup document :" + fileObj.name + " has been created successfully!");
But when I run it, FMS throw the error as following: File operation open failed ; TypeError: fileObj has no properties.
Can you help me ? Thanks in advance.
Supplement: The text file named test.txt doesn't exist before create the fileObj, an instance of File Class.

Is MyApp the name of the application directory, or is it a child of the application directory? If myApp is the app name, just use test.txt as the path flag in the file constructor.

How to activate another worksheet in excel file and write data into it

Hi,
I am writing an automation program to collect test data and write the data to an excel file.

Using cfhttp to read a page and write its contents to a file.

Hi,
I am trying to get a feed of my ebay store listings to load
into froogle. Unfortunately, ebay provides the feed as a website
not a file and froogle (via GoogleBase) needs the file to be
submitted as an XML file.
Is there a way to use something like cfhttp to load up the
page where the feed is located, scan the page and write it's
contents into an XML file that I can then load up to GoogleBase???
thanks for the help.

ignore me now.... I answered my own question a short while
ago.
for anyone who cares....
I used CFHTTP to get the page and then used a cffile to write
the #cfhttp.filecontent# into the new file!

How can i go to different worksheets and go to different cells and change the values and save the file.

You can setup an ODBC connection to the Excel file and update the file with JDBC, using the JDBC-ODBC bridge.
Hope this helps

Comparing an excel file to and xml file and appending data to the xml file

I have an xml file (mapsource) and an excel file. One of the columns in the excel file matches up with a node in the xml file. I want to be able to loop through both files and add a new node to the xml file where the one of the columns in the excel file matches a node in the xml file.
I can create a query object out of the excel dosument using the cfspreadsheet tag.
I'm able to use xmlparse to create a xml document object from the xml file.
What I would like to do is add col_3 from the excel spreadsheet as a new node when col_2 is equal to gpx.wpt.name.xmltext of the xml object.
Any help or direction would be very helpful!

Read a bfile and write its contents in a file stored in my hard disk

I will try to describe my problem as clearly as I can.
I have created a table that includes a LOB column "BFILE"
Then I'm trying to READ the BFILE stored in our database using the
DBMS_LOB package.
so far so good.
Now I want to write these data that I have read in the step above in a file
saved in my local disk. The problem is, since the file in databse is
stored as binary and I read Raw Data , I cannot create an exact copy of this
file. It seems that It doesn't write the RAW data in the binary format.
I have used the DBMS_LOB.READ to read the data and it works fine.
Now I want to create a file in my local disk and dump the data that I have
read from the BFILE that has been initially stored in the database.
Is there any solution to this problem?
I hope to hear from you soon
Thanks in advance

I haven't looked closely, but my spidey sense tingles at this:
new FileOutputStream(MPath)This will clobber (erase) the previous contents of the file. Open in append mode:
new FileOutputStream(MPath, true)Of course, if the file exists before you run this code, you will end up append to the original contents. If that is not wanted, consider using File's delete method first.

Trying to write data to a text file using java.io.File

I am trying to create a text file and write data to it by using java.io.File and . I am using JDeveloper 10.1.3.2.0. When I try run the program I get a java.lang.NullPointerException error. Here is the snippet of code that I believe is calling the class that's causing the problem:
String fpath = "/test.html";
FileOutputStream out = new FileOutputStream(fpath);
PrintStream pout = new PrintStream(out);
Do I need to add additional locations for source files or am I doing something wrong? Any suggestions would be appreciated.
Thank you.

This class contained some other functions i've deleted, but i think it still works.
That enables to create a log (.txt file) that you can fill line by line.
Each line start by the current system date. This class was used in swing application, but could work in a web app.

Find a string in a file and write a new text after it

hi
i try to search a string in a small text file. after this position I should write a new text (it is not the end of the text, it could be somewhere between).
I tried to solve this with the StrginTokenizer, but it does not work properly, any other ideas how to solve this?
thanks for your comments
steinfresser

To insert text into the middle of a file you use the process that has been used since the first text editor was invented over 50 years ago:
1. Read the text from the file up to the insert point, and write it to a new file.
2. Write the inserted text to the new file.
3. Read the rest of the text from the file, and write it to the new file.
4. Delete the file.
5. Rename the new file.

Read the file and write the data into string or int

Ok, here's another rookie question.
I got to read the line from the file and store it in the memory as string or integer.
I wrote this code:
File inputFile = new File("c:/xxx.yyy");
String outputString = new String();
FileReader c1 = new FileReader(inputFile);
StringWriter d1 = new StringWriter(outputString);
int data;
         while((data = c1.read()) != -1)
             d1.write(data);
             System.out.println(data);
         c1.close();
         d1.close();This is how I see it, but it cannot be even compiled because there is no such thing as StringWriter(String) wich I find completely irrational. So tell me, am I retarded or what? No, but seriosly, please help the newbie to understand these streams, am I supposed to use some kind of buffer? Any help appreciated.

A String is an immutable. You cannot update a String.
A new String() is basically the same as an empty String ""
An empty StringWriter can be created with new StringWriter().
If you use a BufferedReader you can call readLine().
BufferedReader in = new BufferedReader(new FileReader(filename));
String line;
while((line = in.readLine()) != null) {
System.out.println(line);
}
