Reading/Writing Multiple Files From/To Socket

I'm have a problem in recognizing end of file in socket.
when I write files one after another using object input stream wrapped on the socket's input stream.
on one side:
while((n = send_file_input_stream[ i ].read(buff)!=-1)
socket_output_stream.write(buff,0,n)
on the other side:
while((n = socket_input_stream.read(buff)!=-1)
recv_file_output_stream[ i ].write(buff,0,n)
this process happens for i=1..N files
1) how can i signal the socket That EOF occures ?
2) how can the recieving socket stream recognize it?
3) Is there a simple mechnism for transffering files in java
from dir to dir from disk to socket ?
like copy(InputStream from,OutputStram to)
Thanks
Joseph

one way is to write something as an end of file marker after each file, say character 255, just make sure you escape any 255's in the file (say by sending two 255's)
The other end then needs to look for the 255's, if it gets one on its own its the end of the file. If it get's two together its a single 255 thats part of the file.
If that seems a bit complicated you could send a header with the count of bytes before each file, the receiving end then just has to count bytes.
Another way is to use a new connection for each file (probably also the easiest)

Stax reading /writing need help from xml guru plz

hi, i have been told that stax reading /writing should involve no overhead and that is why i use it and i am now able to write my large data to file, but using my reader i seem to run out of memory, using netbeans profiler i ahve found that char[] seems to be the problem,
by backtracing i ahve found that javax.xml.parser.SAXParser.parse calls the xerces packages which eventually leads to the char[ ], now my code for my reader is attatched here...

}i thought it may have been a recursive problme, hence having so many instance variables instead of local ones but that hasn't helped.
all i need at the end of this is a Collection which holds an array of testCollections, which holds an array of cCounts and i was able to hold all of this in memory as all i am loading is what was in memory before it was written.
can someone plz help
ps when i use tail in unix to read the end of the xml file it doesnt work correctly as i cannot specify the number of lines to show, it shows all of the file as thought it is not split into lines or contains new line chars or anything, it is stored as one long stream, is this correct??
here is a snippet of the xml file:

please if anyone has any ideas from this code why a char[] would use 50% of the memory taken, and that the average age seems to show that the same one continues to grow..
thanks in advance
danny =)

hi, i am still having lo luck with reading the xml data back into memory, as i have said before, the netbeans profiler is telling me it is a char[] that is using 50% of the memory but i cannot see how a char[] is created, my code doesn't so it must be the xml code...plz help

Help on reading from and writing to a file !!!!!!!!!!!!!!!!

hi there
anyone can help me on how to write and read from a file? how can i read one string at a time instead of a char. thank you.

You can do this with classes FileReader and FileWriter directly, but it's easiest to wrap these with other classes and call methods on those to read and write a string. All of the classes used below are in the java.io package. The code fragments just print any I/O exceptions to stderr. Replace filename with the name of the file you want to use.
To write a string to a file:
String s = "hello";
try {
FileWriter fw = new FileWriter("filename");
PrintWriter pr = new PrintWriter(fw);
pr.println(s); // write a string with a newline at the end
// pr.print(s); // write a string without a newline at the end
pr.close(); // must close for string to be written
} catch (IOException e) {
System.out.println(e);
To read a string from a file:
String s;
try {
BufferedReader br = new BufferedReader(new FileReader("filename"));
s = br.readLine();
} catch (IOException e) {
System.out.println(e);

Use the StringTokenizer to break up the line
File newFile = new File("text.txt");
BufferedReader in = new BufferedReader(new FileReader (newFile));
String line;
while((line = in.readLine()) != null){
StringTokenizer st = new StringTokenizer(inputLine, " ");
while(st.hasMoreTokens()){
// do something with the token
// e.g:
// String lc = st.nextToken().toLowerCase()
hope that helps

The text editor is the text area that you use on the webmail (Yahoo, Hotmail) website to create a new mail.
You can compare that with the ''Post new message'' text area that you use to create a new post on this forum.
Just above the text area that you use to enter the message text there is usually a button bar with buttons that allows some text formatting like Bold and Italic and can also include a button to make a clickable hyperlink.

Dear All
I have a requirement to read/write excel files in .xlsx format. I am good in doing it with .xls format using jxl.jar. The jxl.jar doesn't support .xlsx format. Kindly help me in understanding how do I need to proceed on reading/writing .xlsx files using Webdynpro for Java.
Thanks and Regards
Ramamoorthy D

i am using jdk 1.6.22 and IBM WebSphere
when i use poi-3.6-20091214.jar and poi-ooxml-3.6-20091214.jar to read .xlsx file. but i am getting following errors
The project was not built since its classpath is incomplete. Cannot find the class
file for java.lang.Iterable. Fix the classpath then try rebuilding this project.
This compilation unit indirectly references the missing type java.lang.Iterable

HELP - Buffered Reader

Below is a portion of my program, its a simple app, that is supposed to read a policy number, and then display the results. I can't get it to read the file, or output onto the app. Any help would be appreciated.
the file is called loans.txt and a line looks like this...
12322|Smith, Dennis|456 Westfield Blvd|Westfield, IN 46033|$2,500|1/1/2001|7/11/2005|None
public void GetFile(){
//User's entered policy number is stored here
String Policy_Num_Entered = SearchFor.getText();
/*If the the policy is found in loans.txt, sucess will be changed to 1,
otherwise it will stay 0 and be used to output a "I'm Sorry message*/
int sucess = 0;
//Try Catch Block
try{
BufferedReader br = new BufferedReader(new FileReader(file));
//Access the first line of loans.txt
String line = br.readLine();
//Read the # of lines in loans.txt
LineNumberReader read = new LineNumberReader(new FileReader(file));
//Assign the # of lines to count
int count = read.getLineNumber();
//Item being looked by the String Tokenizer
String Item;
//For loop, looping the # of times a line must be read
for(int x = 0; x < count; x++){
//While Line is not empty, proceed
while ( line != null )
//Read individual words of the line from loans.txt
StringTokenizer tokenizer = new StringTokenizer(line, "|");
Item = tokenizer.nextToken();

//Access the first line of loans.txt
String line = br.readLine();
//Read the # of lines in loans.txt

How Do I read a String as an XML and reply?

Hello there to everyone reading my Post !
I am entering a total new subject in my learning about Java Programming, where I will need to interact with a server, I was wondering If somebody could help me with a Question I have; here it is:
A server provided me a Socket, (and that is of course an IP address and a Port), And I am supposed to connect to that server using a Java program that connects to servers using a Socket class, then I am supposed to send a String representing a valid XML, and then the server replies me With another String representing a valid XML which I am supposed to store in a String type.
Is this exact write/read operation possible? If so, could someone please give me some code to solve this problem?
PD: The server Does this operation only: recieve/send Strings. as its called transactional switch.
Sorry If I have put this Query in the Wrong Forum, I have put it in Networking also, just in case. Excuse me for any inconveniences.

I am supposed to send a String representing a valid XML.what do you mean? do you want to send value that you get from XML doc or what? cos i don't understand about "String representing a valid XML". is it XML document exists or not? can you give us more detail about what you asking for.

String type container element truncated in email

Hi Folks
In the email step of the workflow I have used a string type variable ( Notes of approver of ESS workflow ). The variable is populated completely in the container element in workflow log, but in the email body it's getting truncated after about 80 characters. I did apply the note 975947 but it did not help. Appreciate if anyone can let me know the fix for this.
Regards
Rajeev

I Know that EMAIL subject has a limitation upto 80 characters.
so you can do like this, create a internal table with one variable of 132 chanracters.
Pass this variable to that table.
so while inserting the table in email body, you will be asked to choose one of the options.
there you choose an with line break, it will appear in your editor as&it_tab##&.
Then definitely all the contents will be displayed.

App for editing/reading/writing Excel, Word, Windows notepad text documents

I was wondering if any of you's could recommend some apps (from experience) that would allow me to, edit/read/write Excel, Word, Windows notepad text documents.
I could make do with an app that would do the above but without the ability to create, edit Windows notepad text documents. But been able to read, write, edit Word and Excel documents would have to be a must.
Thanks in advance.

Thanks everyone for the help it was much appreciated.
After debating, I decided on Docs To Go at £9.99. For this amount its a universal app and as such I can have it installed on my iPhone as well as my iPad (which is what I have done), so £5 for to have it on each device is good value I feel. Quick Office on the other hand would have cost £8.99 for the iPad version and £5.99 for the iPhone version a total of almost £15, which is quite a bit more than I paid for Docs To Go.
Upto now, I find Docs To Go does everything I want from it, with regards to editing, reading, writing my Excel files. I tried transferring a Microsoft Windows Notepad text document over to the iPad/iPhone, I was able to read this and also add additional text/words to it and save it too. I do use text documents sometimes because if I want to add them onto a friend's computer for example, I know that they will be able to read them because with them having a Windows PC and also my friend does not have the Microsoft Office program on their PC.
The transferring of files from the computer to the iPhone/iPad is done via a free download of the Docs To Go desktop software program (which is both PC and Mac) compatible). You first need to go into the Docs To Go app and select 'ADD DESKTOP'. This then allows you to add a device to the Docs To Go desktop program thus enabling transfer. You are shown a pin number on the screen which you enter into the Docs To Go app, this procedure only needs to be done once.
The Docs To Go desktop program creates a folder during installation, where all the files etc are stored that are transferred/going to be transferred over are kept.
Some people might think needing to use a program to transfer files over is a bit of a nuisance, when other similar programs allow transfer via a web browser. Personally I find that those programs, the transfer is a bit cumbersome and can be a bit slow. I find the transfer via the Docs To Go desktop program is a lot easier and faster than using the web browser. The only downside I can see with needing to use the Docs To Go desktop program is that.. If I am at a friend's house and want to transfer something on to my iPhone/iPad. My friend would need to install the program, but saying that, its a very small program and its not a big deal having to install it. If they didn't want to install it, then there is either emailing the file or transferring the file to my Dropbox account. I forgot to mention that Docs To Go supports cloud/online storage such as Dropbox, GoogleDocs as well as others.
Once the above is done, you switch the wifi on, load the Docs To Go app, load the Docs To Go desktop program. You then just drag and drop the folders etc that you are wanting transferred over into the The Docs To Go desktop program, then you click on the circular arrow button and they are then transferred over onto the iPhone/iPad.
Once on the iPhone/iPad, you can view them, add additional information, when you make any changes you can press the circular arrow symbol (bottom left of the Docs To Go app) on the Docs To Go app and the changes are then synced back to the same file that is stored on the computer, so its very easy to keep everything in sync and up to date.
It is possible whilst using a Microsoft Word document to have a word count, you just touch the symbol at the bottom right of the Docs To Go app and choose Word Count from the drop down menu. I have heard a few people in some reviews saying that 'Docs To Go doesn't have a word count', when indeed it does.
One surprise is that Docs To Go, does not have a spell checker, but hopefully during later updates, the feature might be added. I sent my feedback to Docs To Go requesting this feature on future releases. I expect that there will be many other people who have requested this feature too.
I just thought I would share my experience with using Docs To Go.
Thanks again everyone for the help, it was much appreciated

Textarea with Read Only Condition Type

A have a textarea (database field with Varchar2(4000) with the Read Only Condition Type set to Request != Expression 1. Works fine, except that data presented as a long 1 line text (like a Displayed text) when condition meet (no vertical scrollbar).
Am i missing some additional settings.

the easiest way to get the read-only version of your textarea item to appear more like your read/write version is to add some style specifications into the "Read Only Element Table Cell(s) Attributes" field that's right below where you specified your read-only conditions ("Expression 1" and "Expresssion 2"). as the name suggests, values entered into that field end up in the table data tag for the cell in which your read-only content is placed. added style specifications for height and width would help you control how the text is spread across your page. you can/should also consider using background and color style attributes to color the table cell the way we're used to seeing read-only data ("grayed out"). so though my colors are way off, a string like this...
style="width:16px;height:30px;background:#C5D5C5;color:666666;font-weight:bold;font-size:12pt"
...in that "Read Only Element Table Cell(s) Attributes" field would format your read-only data closer to what you're going for. at the least, it'd give you an idea for the type of control you have.
for extremists, there's also another approach: if you want absolute and total control over the way your textarea item's data is displayed, you could display your item's data in an HTML region instead of as the item directly. for instance, you mentioned you liked that scroll bar. you could achieve the scroll bar by defining your table, the scroll bar class, and table cell in an HTML region. say we saved your textarea item's data to a hidden item called P1_MY_TEXTAREAS_DATA. i'm pretty sure this html would let you show that data in that scrollable non-updatable format you're shootin' for...
<style type="text/css">
.scrollarea{
font-size: 10pt;height:250px;width:100%;text-align:left;
background-color:#ffffff;color:black;padding:0px 0px 0px 0px;margin:0px;overflow: auto;
float:left;}
</style>
<div class="scrollarea">
<table summary="" width="100%"><tr>
<td style="width:16px;height:300px;border:4px;margin-left:4px;margin-right:9px">
&P1_MY_TEXTAREAS_DATA
</td></tr></table><div>
...see? by defining your own table, you get the easy opportunity to wrap it in those div tags that call the scrollarea class. also note that i just referenced the content of your textarea item with that ampersand syntax (&P1_MY_TEXTAREAS_DATA). you could, of course, keep things cleaner by defining your scrollarea class in a css, but that's your call.
hope this helps,

Log the local variables (string type) to the database (SQL Server)

i have a customized PreUUT callback so that my own VI gets the information from barcode. it contains serial number as well as other information. i am collecting the information into local variables of the PreUUT callback.
Now i want to log the local variables (string type) to the database (SQL Server).
i have a successful connection to the database and i am using a generic recordset schema.
can anyone help me how to do it?
also shall i have to create the corrosponding fields (columns) in the database? or is there any option in TestStand4.0 to do it?

Hello i like original,
After re-reading your original message, I think I might have a better understanding of what you would like to do. I have included a few links to Knowledge Base and Developer Zone articles that should be very useful for you. I have included these links below:

Still need help with case sensitive strings

Hello guy! Sorry to trouble you with the same problem again,
but i still need help!
"I am trying to create a scrypt that will compare a String
with an editable text that the user should type to match that
String. I was able to do that, but the problem is that is not case
sensitive, even with the adobe help telling me that strings are
case sensitive. Do you guys know how to make that comparison match
only if all the field has the right upper and lower case letters?
on exitframe
if field "t:texto1" = "Residencial Serra Verde"then
go to next
end if
end
|----> thats the one Im using!"
There were 2 replys but both of them didnt work, and the
second one even made the director crash, corrupting even previously
files that had nothing to do with the initial problem..
first solution given --
If you put each item that you are comparing into a list, it
magically
makes it case sensitive. Just put list brackets around each
item.
on exitframe
if [field "t:texto1"] = ["Residencial Serra Verde"] then
go to next
end if
end
Second solution given--
The = operator is not case-sensitive when used on strings,
but the < and > operators are case-sensitive.
So another way to do this is to check if the string is
neither greater than nor less than the target string:
vExpected = "Residencial Serra Verde"
vInput = field "t:texto 1"
if vExpected < vInput then
-- ignore
else if vExpected > vInput then
-- ignore
else
-- vExpected is a case-sensitive match for vInput
go next
end if
So any new solutions??
Thanks in advance!!

The first solution does in fact work and is probably the most
efficient way
of doing it. You can verify that it works by starting with a
new director
movie and adding a field named "t:texto1" into the cast with
the text
"Residencial Serra Verde" in the field. Next type the
following command in
the message window and press Enter
put [field "t:texto1"] = ["Residencial Serra Verde"]
You will see it return 1 which means True. Next, make the R
in the field
lower case and execute the command in the message window, it
will return 0
(true).
Now that you know this works, you need to dig deeper in your
code to find
what the problem is. Any more info you can supply?

Help needed for writing query

help needed for writing query
i have the following tables(with data) as mentioned below
FK*-foregin key (SUBJECTS)
FK**-foregin key (COMBINATION)
1)SUBJECTS(table name)
SUB_ID(NUMBER) SUB_CODE(VARCHAR2) SUB_NAME (VARCHAR2)
2           02           Computer Science
3           03           Physics
4           04           Chemistry
5           05           Mathematics
7           07           Commerce
8           08           Computer Applications
9           09           Biology
2)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2) SUB_ID1(NUMBER(FK*)) SUB_ID2(NUMBER(FK*)) SUB_ID3(NUMBER(FK*)) SUBJ_ID4(NUMBER(FK*))
383           S1      9           4           2           3
384           S2      4           2           5           3
---------I actually designed the ABOVE table also like this
3) a)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2)
383           S1
384           S2
b)COMBINATION_DET
COMBDET_ID(NUMBER) COMB_ID(FK**) SUB_ID(FK*)
1               383          9
2               383          4
3               383          2
4               383          3
5               384          4
6               384          2
7               384          5
8               384          3
Business rule: a combination consists of a maximum of 4 subjects (must contain)
and the user is less relevant to a COMB_NAME(name of combinations) but user need
the subjects contained in combinations
i need the following output
COMB_ID COMB_NAME SUBJECT1 SUBJECT2      SUBJECT3      SUBJECT4
383     S1     Biology Chemistry      Computer Science Physics
384     S2     Chemistry Computer Science Mathematics Physics
or even this is enough(what i actually needed)
COMB_ID     subjects
383           Biology,Chemistry,Computer Science,Physics
384           Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --Pradeesh

Well I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say.
