Reading Multiple lines in a file Using File Adapter

Hi All,
Iam new to this technology.How to read multiple lines in a file using file adapter.Brief me with the methodology.

I didn't look at anything else but if you want to write more than one line ever to your file you should change this
out = new FileOutputStream("Calculation.log");to this...
out = new FileOutputStream("Calculation.log",true);A quick look at the API reveals the follow constructor FileOutputStream(File file, boolean append) append means should I add on the end of the file or over-write what is there.
By default you over-write. So in our case we say true instead which says add on to what is there.
At the end of that little snippet you shoudl be closing that stream as well.
So where you have
p.close();You should have
p.close();
out.close();

Hello, 
 
I've been using the PWS to run the website on NT workstation 4.0. It was working
fine. 
The URL should be as below: 
http://127.0.0.1/index.htm or http://localhost/index.htm
And suddently, it stops working, it can't find the connection. I tried to figure
out what's going on, but still NO CLUES. Does anyone
know what's going on? Please see the link for more.... I believe that I setup
everything correctly and the bugs still flying in the server.... 
Thank you for your help.

Hi!
This is a possible solution to your problem.
import java.io.*;
class AddressExtractor {
 public static void main(String args[]) throws IOException{
 //retrieve the commandline parameters
 String fileName = "default.html";
 if (args.length != 0) fileName =args[0];
 else {
 System.out.println("Usage : java AddressExtractor <htmlfile>");
 System.exit(0);
 BufferedReader in = new BufferedReader(new FileReader(new File(fileName)));
 StreamTokenizer st = new StreamTokenizer(in);
 st.lowerCaseMode(true);
 st.wordChars('/','/'); //include '/' chars as part of token
 st.wordChars(':',':'); //include ':' chars as part of token
 st.quoteChar('\"'); //set the " quote char
 int i;
 while (st.ttype != StreamTokenizer.TT_EOF) {
 i = st.nextToken();
 if (st.ttype == StreamTokenizer.TT_WORD) {
 if (st.sval.equals("href")) {
 i = st.nextToken(); //the next token (assumed) is the '=' sign
 i = st.nextToken(); //then after it is the href value.
 getURL(st.sval); //retrieve address
 in.close();
 static void getURL(String s) {
 //Check string if it has http:// and truncate if it does
 if (s.indexOf("http://") > -1) {
 s = s.substring(s.indexOf("http://") + 7, s.length());
 //check if not mailto: do not print otherwise
 if (s.indexOf("mailto:") != -1) return;
 //printout anything after http:// and the next '/'
 //if no '/' then print all
 if (s.indexOf('/') > -1) {
 System.out.println(s.substring(0, s.indexOf('/')));
 } else System.out.println(s);
}Hope this helps. I used static methods instead of encapsulating everyting into a class.

StringTokenizer to read multiple lines

I've been struggling to make my program to read multiple lines from the input text
input5.txt:
-.1 -2.3 -45.678 -90
.1 .23 .45678 .90
1 2.3 4.56
0
and the program will stop reading when it sees 0 in the line. What i got was a nullPointerException, it reads a single line fine, but when it comes to multiple lines, it messes up. Heres a portion of my program code:
while (info1 != null && !end)
 tokenizer = new StringTokenizer(info1, " \t\r\n");
 while ((info1 = stdin.readLine()) != null && info1.length() != 0)
 if (tokenizer.hasMoreTokens())
 // temp is a dummy String to help for counting limit.
 temp = tokenizer.nextToken();
 dummy [limit] = temp;
 limit++;
 numbers = new float [limit];
 while (count < limit)
 while (tokenizer2.hasMoreTokens() && num1 != 0.0 && num1 != 0)
 num1 = Float.parseFloat(dummy[count]);
 numbers[count] = num1;
 count++;
 end = true;
}

You need to move the "new StringTokenizer" into the following while loop

Reading Multiple lines using File Adapter in PI 7.1

Hi Friends,
We are using PI 7.1 Service pack 4, scenario is File to IDOC .
I am using Sender File Adapter with File content conversion for fixed lengths to read file from FTP XI-SAP.
File Format :
EDI_DC40 , A, B, C, D, E
E1WPU01, F, G,H, I
E1WPU02 , J,K,L
E1WPU02 , J,K,L
I have maintained Fcc parameters . I am able to read files for mulitple rows when manually set the count in recorset structure
like :
Recordset Structure : EDI_DC40,1, E1WPU01,1, E1WPU02,2...
Problem is when I set * in Recorset Structure : EDI_DC40,1, E1WPU01,,E1WPU02,
Nothing is coming .
Could anyone help me how to resolve this issue.
Regards,
Vijay

Hi Vijay,
As u mentioned in earlier post...
keyfieldName = TABNAM
EDI_DC40.fieldNames :
EDI_DC40. fieldFixedLengths:
EDI_DC40.keyFieldValue :
E1WPU01.fieldNames :
E1WPU01.fieldFixedLengths:
E1WPU01.keyFieldValue
E1WPU02.fieldNames :
E1WPU02.fieldFixedLengths:
E1WPU02.keyFieldValue
Here actually you are trying to get the key field value even from EDI_DC40 and E1WPU01 also....
So obviously u dnt have those values in that rows so.. it cannot get the rows....
So please u try this one..... The same FCC but remove the 2 lines.... for EDI_DC40 and E1WPU01
keyfieldName = TABNAM
EDI_DC40.fieldNames :
EDI_DC40. fieldFixedLengths:
E1WPU01.fieldNames :
E1WPU01.fieldFixedLengths:
E1WPU02.fieldNames :
E1WPU02.fieldFixedLengths:
E1WPU02.keyFieldValue
I hope this wil solve ur problem..
Lemme know if any issues...
Thanks & Regards,

How to handle multiple threads to read one line from a file each time?

Dear Sir or Madam,
I'm new to multiple threads java programming. What I want to do is as following:
1. I'm writing a program to read one line of text from a very large file, and then do some process on this one line of text, then read the next line of text from this file, then process on this line of text, ...... When reach the end of the file, close the file.
This is a single thread scenario.
2. To fullly untilized computer resource, I want to create multiple threads to process this large file.
One thing is very important is that each line of text in the large file has to be read sequentially. This means that the first line of text in the large file is read first, then the second line, then the third line ......
My question is that if I create multiple threads to process the same file, how can I make sure that different threads will read the line of text from the same file sequentially?
I don't have enough experience on java multiple threads programming, so it will be very appreaciated if you can help me on this as soon as you are available.
Thanks and regards,
Steven Wu

A better solutoin would be to have a single thread that reads each line an puts it into a queue, and then multiple threads reading from the queue to process these lines.
This will only be effective if the amount of processing to be done on each line is very large compared to how long it takes to read the line, or if you have more than one CPU on your machine.

Multiple Header line in Receiver File adapter

Hi,
I have an issue in Receiver File adapter with multiple header lines. I am able to get only 1 header lines in the receiver file but not multiple header lines with 'nl' since it is static in file mode
[CommunityTag:Header]
empNo,EmpName,Age
[CommunityTag]
I tried with the below in content conversion one as below with no luck
Root.addHeaderLine=1
Root.headerLine=[CommunityTag:Header] 'nl' empNo,EmpName,Age 'nl' [CommunityTag]
Root.fiedSeparator=,
Root.endSeparator='nl'
I am getting the Header line as same row as static text.
Can you advise this.

Hi Gabriel, I suggest to produce the header lines from additional nodes in the message payload. That means you need to modify the data type of the target message in order to generate an extra structure in the payload. Use constants in message mapping to generate the header column names, e.g.
<Header>
<H1>CommunityTag:Header</H1>
<H2>empNo,EmpName,Age</H2>
<H3>CommunityTag</H3>
</Header>
In content conversion you have to convert the Header row with
Header.endSeparator='nl'
You won't need parameter addHeaderLine anymore then.

Problem while reading a line from a file

Starting Point of Û is 9 and if
V1:=substr(''abcdefghÛLasasa',9,3)
result is v1='ÛLas' which is invalid
can i anybody help me out in resolving this problem

Hello,
What is your oracle version? And what is your expected result.
I used the same string and this is my output on 10.2.

Script or command line to comment out multiple lines in flat files

I am looking for a way to go through multiple flat files within the same directory for the occurance of a server name and if found to insert a comment (#) at the beginning of the line. Currently, I am grepping for the server name within the directory and then doing a vi on each individual flat file to comment out the line. The server name is separated by the pipe (|) symbol and each line of every file is in this format:
webservers:WEBSERVER|Env Name|servername|application name
So, in the above, I am grepping for the servername part and if found in there, I want to change the line to:
#webservers:WEBSERVER|Env Name|servername|application name
I would think there would be a way of doing this either with command line Perl or with maybe awk or sed. Any suggestions would be greatly appreciated.

You could do something like this with a ksh shell script:
#!/usr/bin/ksh
for file in `ls`; do
echo $file
sed 's/^webserver/#webserver/g' $file > $file.parsed; mv $file.parsed $file
doneThis will go through everyfile in the directory and search for "start of line" webserver and replace it with "#webserver". Then the file will get move back to the original file name.
If you just want to change certain files ie. only filenames with the word "server" in it, then change:
for file in `ls`; do to something like
for file in `ls *server*`; doHope this help...
Cheers

Reading multiple messages from XML file.

Hi, I have such XML file:
<?xml version="1.0" encoding="UTF-8"?>
<dataroot xmlns:od="urn:schemas-microsoft-com:officedata" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:SchemaLocation="xml_table.xsd" generated="2007-09-30T17:40:55">

</xml_table>
<xml_table>
<id>2</id>
<name>SomeName</name>
<phone>2929292</phone>
</xml_table>
</dataroot>
I have past this file through file adapter (using schema definition etc). I can read content of file:
ora:getContentAsString(bpws:getVariableData('XMLType','dataroot'))
But I can’t get xml element value, for example name... :
bpws:getVariableData('XMLType','dataroot','/ns15:dataroot/ns15:xml_table/ns15:name')
Error: com.oracle.bpel.client.delivery.ReceiveTimeOutException: Waiting for response has timed out. The conversation id is 16d59568a10954ee:-4254ad7e:11580ba6d96:-7f38. Please check the process instance for detail.

Result: oracle.xml.parser.v2.XMLNodeList@14cb6a0
Etc.
How can I get value through assign method?

It looks to me that your XML data does not have a default namespace.
You defined namespace "ns15" in your bpel process.
Are you able to set the default name space in your xml data.
