How to read the contents of a file present in local file system

Hi ABAP Experts,
I want to read the file contents of a file in the local system. I want to read it stream based i.e if the file is if 100kb in size, i want to read the first 100bytes at one time, next 50 kb after, and remaining some other time. Is this possible. I know that with GUI_UPLOAD i can get the total contents into a xstring.
But how to resolve the following i am not sure. Can you please help.
Thanks & Regards,
Vinay.

In order to read the content of the Redo Log files, you should use Logminer Utility
Please refer to the documentation for more information:

package java.io
InputStream.read(): int
Reads the next byte of data from the input stream.
Implementation:
InputStreamReader
An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.

Help me...How to read the content if "Transfer-Encoding:chunked" is used?

I am doing a project for internet control using Java,PHP and MySql.All sites should go through the proxy server only.If the HTTP header contains Content-Length,am getting the content length as below:
public class HTTPResponseReader extends HTTPMessageReader
    String statusCode;
    public HTTPResponseReader(InputStream istream) throws IOException,                     NoSuchElementException
BufferedInputStream distream = new BufferedInputStream(istream);
retrieveHeader(distream);
StringTokenizer st = new StringTokenizer(new String(HTTPMessageReader.toArray(header)));
versionProtocol = st.nextToken();
statusCode = st.nextToken();
String s;
while (st.hasMoreTokens())
        s = st.nextToken();
        if (s.equals("Transfer-Encoding:"))
       transferEncoding = new String(st.nextToken());
     if (s.equals("Content-Length:"))
       contentLength = Integer.parseInt(st.nextToken());
     if (s.equals("Connection:"))
      connection = new String(st.nextToken());
      if (connection.equals("keep-alive")) mustCloseConnection = false;
   retrieveBody(distream);
}After getting the Content-Length,i used read method to read the content upto that content length.Then i concatenated the HTTP header and body and the requested site was opened.But some sites dont have Content-Length.Instead of that,Transfer-Encoding is used.I got the HTTP Response header as "Transfer-Encoding:chunked" for some sites.If this encoding is used how to get the length of the message body and how to read the content.
Can anybody help me.
Thanks in advance...

Why don't you use HttpUrlConnection class to retrieve data from HTTP server? This class already supports chunked encoding...
If you want to do anything by yourself then you need to read HTTP RFC and find all required information. Well in two words you may reject advanced encoding by specifying HTTP 1.0 in your request or download chunked answer manually. Read RFC anyway :)

How to read the contents of XML file from my java code

All,
I created an rtf report for one of my EBS reports. Now I want to email this report to several people. Using Tim's blog I implemented the email part. I am sending emails to myself based on the USERID logic.
However I want to email to different people other then me. My email addresses are in the XML file.
From the java program which sends the email, how can I read the fields from XML file. If any one has done this, Please point me to the right examples.
Please let me know if there are any exmaples/BLOG's which explain how to do this(basically read the contents of XML file in the Java program).
Thank You,

try this code to store image file in back end system.
IWDResource res=wdContext.currentMyDataElement().getPictureres();
          InputStream in=res.read(false);
          ByteArrayOutputStream bout=new ByteArrayOutputStream();

          bout.write(part,0,length);
          in.close();

If it is other than image file like word or text then try this in action
IWDResource resource = wdContext.currentResElement().getResorce(); // your existing handle to the upload resource type
            try {
               InputStream stream = resource.read(true);

Hi Harshal ,
I dont think there is such function module /BAPI/Class-Method .

How to read the content of a blob col along with other cols as pipe delimit

Hi,
I would like to read the blob content along with the other columns . Assume table TAB1 has columns Response_log, Empcode and Ename. Here Response_log col is a blob data type, and the content of the blob is an xml file.Now i would like to read the content of the xml file of response_log column along with Empcode and Ename as pipe delimited . or else the best option would be to write to a text file with name extract.txt with the data being pipe delimited .
create table tab1(
response_log blob,
empcode number,
ename varchar2(50 byte)
)Sample code goes something like the one below .
select xmltype( response_log, nls_charset_id( 'char_cs' ) ).getclobval() || '|' || empcode || '|' || ename
from tab1 Can I have any other alternate way for this.
Please advice

Just Now one example is given in HOW TO WRITE ,SAVE A FILE IN BLOB COLUMN

How to read the content of "Transfer-Encoding: chunked" header

Can anybody tell me how to get or read the value of transfer encoding.
I got the HTTP Response header as "Transfer-Encoding: chunked".But i can't get the chunk size or the chunked data.
Without getting those details i cant read the content of the site.If Content-Length is in the HTTP header,i can read upto that length.But in this Transfer-Encoding case,i cant know any other details except the value "chunked".So suggest me to read the content of the site using Transfer-Encoding.
Message was edited by:
VeeraLakshmi

I used HTTPURLConnection also.If i use that am getting the values in request headers only and not in Response headers.So i cant read the content.
Then i went through RFC 2616.There i can only understand about chunked transfer encoding.Still i cant get any idea to know the chunk-size and the chunked data of the transfer encoding.Because i am getting the HTTP Header Response as "Transfer-Encoding: chunked".Below that am not getting the size and data.If i know the size or data,i can proceed by converting the hex into bytes and i can read.
