You CANNOT store "www dot abc dot com " any where because that is a site, not data.
So FIRST you must first get the data from that site. How you do that depends on the site and the data you want. This might be a trivial step or in might be very, very complicated. This step has nothing to do with storing anything.
If the sight is VERY simple or you have NO need to store images then you might end up with a single html string which can be stored. However that is very unlikely. If not then you must retrieve all of the different parts from the site, and determine how you want to store those parts. A simple mechanism would be to store the tree (because an extracted html site is going to be representable that way.)
SECOND then you determine how you want to store it. Unless the page is very simple or you extract almost nothing from the page then you would need to either create an significant data structure in the database or you would need to store the entire tree as a blob. Doing that requires that you convert the tree into a single binary format and then store it. You can google for example for storing retrieving blobs.
Finally you presumably have researched exactly what your legal right is to download the contents of that site and store it. Even if you own the site there might be limitations on the content (such as picitures) that disallow you from storing it.

How to create a file and store its contents into another file?
Hi,
I'm having some trouble trying to create a code where I have to to create a file and store its contents into another file?
I read the API, but I'm not certain how this file thing works.
Here's my code so far:
public static void main(String[] args) throws Exception
File file = new File("tasks.txt");
if (file.exists())
System.out.println("File already exists");
System.exit(0);
Scanner scan = new Scanner(System.in);
Scanner scan2 = new Scanner(System.in);
//Scans the input line by line
scan.useDelimiter("\\n");
//Scans the input by tabs
scan2.useDelimiter("\\t");
PrintWriter outputs = new PrintWriter("newtasks.txt");
outputs.print("ok");
outputs.println(3);
outputs.close();
}I managed to change my text into uppercase, but how do I store the uppercase content into another file.
-So this is what I did so far, I took a text file and modified its strings to uppercase.
-Now I need to put those modified strings into another text file, is there a way where I can do that with my current code?
-I already tried printwriter, but it doesn't seem to work
public static void main(String[] args)throws IOException
//Task[] oneHundredTasks = new Task[100];
String uppercase;
String combine;
Scanner scan = null;
FileInputStream in = null;
FileOutputStream out = null;
PrintWriter output = null;
try
scan = new Scanner(new BufferedReader(new FileReader("tasks.txt")));
scan.useDelimiter("\\n");
scan.useDelimiter("\\t");
while (scan.hasNext())
if(!scan.hasNext())
scan.next();
combine = scan.next();
uppercase = combine.toUpperCase();
System.out.println(uppercase);
finally
if (scan != null)
scan.close();
//The program will try the input and output files
try
in = new FileInputStream("tasks.txt");
out = new FileOutputStream("newtasks.txt");
int c;
//The number "-1" is used to indicate that it has reached the end of the stream.
while ((c = in.read()) != -1)
out.write(c);
finally
if (in != null)
in.close();
if (out != null)
out.close();

[email protected]Hi i need to write the data from an XML file to a Microsoft SQL SErver database!
i got a piece of code from the net which allows me to parse th file:
import java.io.IOException;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import org.apache.xerces.parsers.SAXParser;
import java.lang.*;
public class MySaxParser extends DefaultHandler

parser.setContentHandler(MySaxParserInstance);
parser.parse(uri);

idx -= INDENT;
public void startDocument() throws SAXException
idx += INDENT;
public void startElement(String uri,
String localName,
String qName,
Attributes attributes) throws SAXException
idx += INDENT;
System.out.println('\n' + getIndent() + "start element: " + localName);
if (localName.compareTo("Machine") == 0)
System.out.println("YES");
if (attributes.getLength() > 0)
idx += INDENT;
for (int i = 0; i < attributes.getLength(); i++)
attList = attList + attributes.getLocalName(i) + " = " + attributes.getValue(i);
if (i < (attributes.getLength() - 1))
attList = attList + ", ";
idx-= INDENT;
private String getIndent()
StringBuffer sb = new StringBuffer();
for (int i = 0; i < idx; i++)
sb.append(" ");
return sb.toString();
}// END PRGM
Now , am not a very good Java DEv. and i need to find a soln. to this prob within 1 week.
The next step is to write the data to the DB.
Am sending an example of my file:
<Start>
<Machine>
<Hostname> IPCServer </Hostname>
<HostID> 80c04499 </HostID>
<MachineType> sun4u [ID 466748 kern.info] Sun Ultra 5/10 UPA/PCI (UltraSPARC-IIi 360MHz) </MachineType>
<CPU> UltraSPARC-IIi at 360 MHz </CPU>
<Memory> RAM : 512 MB </Memory>
<HostAdapter>
<HA> kern.info] </HA>
</HostAdapter>
<Harddisks>
<HD>
<HD1> c0t0d0 ctrl kern.info] target 0 lun 0 </HD1>
<HD2> ST38420A 8.2 GB </HD2>
</HD>
</Harddisks>
<GraphicCard> m64B : PCI PGX 8-bit +Accel. </GraphicCard>
<NetworkType> hme0 : Fast-Ethernet </NetworkType>
<EthernetAddress> 09:00:30:C1:34:90 </EthernetAddress>
<IPAddress> 149.51.23.140 </IPAddress>
</Machine>
</Start>
Note that i can have more than 1 machines (meaning that i have to loop thru the file to be able to write to the DB)
Cal u tellme what to do!
Even better- do u have a piece of code that will help me understand and implement the database writing portion?
I badly need help here.

How to store email content as a document variable?
Hi there,
I have a question where I need to store the content of an email-service into a txt-file. I guess I should somehow put it in an document variable, how can this be done?
Thanks in advance
Sincerely
KimKim
I would suggest one of the following two methods:
1) Prior to sending the email with the SendEmail service, build the email contents via SetValues and using String process variables. Have one String for the subject (i.e. sSubject) and one for the body (i.e. sBody) and build your content appropriately. You can use multiple SetValues or you could do it all in one. After your email's body is done being built, use a SetValue to set it to a Document variable (i.e. docBody = sBody). You can then use this Document variable as the input to your SendEmail service's body parameter. What you have then is a Document containing all the content of the email's body that you can now write to the filesystem, archive to a repository or do whatever you'd like with. Please note that if you are using HTML formatting for the email's body that your Document variable will literally have the HTML code in it. This means that if you, say, archived the Document to the file system as a .txt and then opened it, you would see all the content but it would have all the HTML code with it. To get around this, you might consider archiving the email contents as a .htm or .html file. This will cause the file to open in the system's default browser for viewing but it will also only display the actual content formatted per your HTML code.
One other thing to note is that if you wanted the subject to be part of the archived file's contents as well, you could simply do a String concatenate of the body String (sBody) to the subject String (sSubject).
2) If the emails you are sending go to the same email box(es) each time, you might consider building a second orchestration that uses an Email endpoint to watch the box(es). With this, you could monitor those inboxes and handle incoming messages appropriately.
Please do let me know if you have any questions.

How to store the content of text_edit in the BSP page to infotype
Hi experts,
I created a bsp page with a text_edit which is for every one that read the page to leave comments...
I tried to store the content of the text_edit to infotype, but failed, I noticed that there is a class named CL_HRRCF_INFOTYPE, has method named read_text and update_text.
I think maybe these methods could help me fulfill the requirement,
I've debug the standard program many times(the standard infotype 5130 used the class CL_HRRCF_INFOTYPE and the methods to store descriptions into infotype.)but still can not figure out how the standard complete the process..
Please help me with this...
Thank you!!So the issue is not with BSP but to find the appropriate method/FM for updating the text. you will get a quicker response in ABAP forum and moving your thread to ABAP forum.

How to store the contents of a text file directly in to a clob field
Hi All,
Could anyone help me to store the contents of a text file (*.txt,*.xml etc)directly in to a clob field.
Thanks in advance
Jayaram.One way is to use sqlloader. Three files are used. A control file, an xml data file, and a file with the path of the xml data file. Here's the control file. It reads load.file, which is the file with the path of the xml data file. It names the path ext_path, and inserts the xml into field xml_field.
CONTENTS OF CONTROL FILE:
load DATA
INFILE 'load.file'
APPEND
INTO TABLE xml_table
( ext_path FILLER CHAR(13),
"XML_FIELD" LOBFILE(ext_fname) TERMINATED BY EOF
CONTENTS OF FILE LOAD.FILE:
/tmp/load.dat
The xml is in the file /tmp/load.dat.

How to store the contents of a file
Hi,
I'm using forms6i and database 10g.
Through forms if a user selects a filename , and clicks a button or something,
the contents of the file should be saved in the database.
The file can be of any type, like .doc,.pdf,.xml,.html etc...
and the contents filed will be of type varchar
Please help me do this..
ThanksDo you really want to save the "Content" of a file or the file itself? If you try to save the contents of a .doc or .pdf in a column with a VARCHAR2 datatype, you are going to corrupt the contents of the file since these file types have binary data in them as well as text. I think you would have greater success storing the actual file in a BLOB column.
Here are a few Oracle Support documents that discuss how to store and retrieve files stored as BLOBs in the database.
Doc ID: 168277.1 - How to Upload Binary Documents Back to Database BLOB Column from Forms
Doc ID: 330146.1 - How to write BLOBs Stored Inside the Database Out to Files.
Hope this helps,
Craig B-)

How to store forms fields into the session ?
Hi All,
I have to store forms fields into the session.
I have four forms (htm forms) in four jsps and there are total 25 fields.
I am inserting all the fields into the database at once while user submit the last form.
I want to use session to store forms fields.
So please anybody tell me how to do that.
Is the following code correct to store the forms fields into
the sesstion........
// creating a session
HttpSession session=request.getSession(true);
// retrieving form fields
String name=request.getParameter("customer_name");
String business=request.getParameter("business");
String address=request.getParameter("address");
and so on....
// store form fields into the session
session.setAttribute("name",name);
session.setAttribute("business",business);
session.setAttribute("address",address);
and so on....
and later on get the value as:
session.getAttribute("name");
session.getAttribute("business");
session.getAttribute("address");
and so on....
OR
is there another way to store form fields into the session.
Please guide and reply with coding.....
Please answer and help.
Thanks
AmitindiaI don't mean to be an *** but I have no desire to help someone so unwilling to think >>and do. Go through some of these tutorial, do the examples in each and you will be far >>better equipped to ask questions:
http://www.google.co.za/search?hl=en&q=%2Bjsp+%2Bjavabean+%2Btutorial&b >>tnG=Google+Search&meta=
I was just asking that if I use the following
<jsp:useBean id="cart" scope="session" class="session.Carts" />
<jsp:setProperty name="cart" property="address" value="myaddress" />
</jsp:useBean>then will I be able to acheive my aim as I have to store form fields into the session and later retreive while user submit the last form.
Please read my question that I have posted.
Am I using the right way................or which is the best way to store form fields into the session and later retrieve them.
please reply
Thanks

DATA lo_el_kna1 TYPE REF TO if_wd_context_element,
DATA lt_kna1 TYPE wd_this->elements_znode.
DATA ls_kna1 TYPE wd_this->element_znode.
lo_nd_kna1 = wd_context->get_child_node( name = wd_this->wdctx_znode ).
lo_el_kna1 = lo_nd_kna1->get_element( ).
lo_el_kna1->get_static_attributes( IMPORTING static_attributes = ls_kna1 ).
modify kna1 from ls_kna1.
