NullPointerException line number is }
I am getting a NullPointerException, and on the line number
reported is }. This closing brace is the closing brace for the
method. Is there any significance to NullPointerException being
reported at the closing brace of a method or is it just likely that
the Exception occurs higher up and the line number is not
being reported correctly.
As others said, you should check to make sure your source and class are in-sync. This is the usual cuase of this problem. If you are still having this issue, you might be having an issue with an IDE or compilation tool. I've had problems where class files were built with the wrong lines. I think it was JBuilder that was doing it but I can't remember.
The way you can verfiy that this is happening is add a new debug statement at the first line of the method that throws the Exception. If you don't see the debugging, you aren't using an up-to-date class. If you do see it and the line number is still bogus, then try compiling from the command line.

Delivery schedule line number in make to order
Hi all,
i am doing make to order scenario with 20 strategy group. In sales order we r defining the different delivery schedule lines.when i run the MRP and getting the plan orders for all the FG material and semifinished material, the sale order number and sale order item number is getting updated in production order . Beside these two , delivery schedule line number is not populated and delivery date is not picking correctly in production order.
please give your valuable suggestion .
i would be highly thankful to u
regards
piyushHi
When you do the MRP Run at MD02, maintain the Delivery Schedules as 3 (schedule lines), so when ever you do the MRP Run, it will run along with the delievry date.

Link between schedule Line Number and Delivery
Is there a link between Schedule line Number and Delivery number ?
Eg. Line item 10 with quantity 100.
has 5 schedule lines..with 5 different delivery dates.
1 . quanity 40
2. quantity 30
3. quantity 20
4. quanity 6
5 quantity 4
For schedule line 1, 2 deliveries were created,
one with quantity 20
another with quantity 15
quantity 5 is still not delivered.
also schedule lines 2,3,4 and 5 are fully delivered.
Is there any table, FM etc in SAP which will give me the link between the schedule line and delivery number ?
Total deliveries created : 6. - But which delivery corresponds to which schedule line ?
Please dont tell me to look VGBEL and VGPOS.. that will just give line item number 10.. I need to get the schedule line number.
Also, RV_SCHEDULE_CHECK_DELIVERIES --> will give me the delivered quantity against each schedule line.
My purpose is to create an ontime delivery report .
a report which list each schedule lines, and tell, how many shipments were late/ontime/early etc..
and for Late ones, how many days late has to be found.
this is where i need the delivery.
No. Of days Late = Actual GI Date - Planned GI Date.
Actual GI date is in the delivery.
Any suggestions ?
Thank you in advance.Hi,

Schedule line number determination - Schedule line category CP(MRP)
Hello All,
I want to know on what basis schedule line numbers getting determined.
Schedule line category: CP-MRP
Sales order line items getting confirmed based on the Planned order--> production order created through MRP run.
I have created sales order line item 1 with 100 quantities. for example I created today. RDD also today.
3 production order created.
Those production orders confirmation date as below.
Production order 1 - 60 quantities - 14.04.2014
Production order 2 - 30 quantities - 16.04.2014
Production order 3: 10 quantities - 18.02.2014.
There are four schedule lines for the line item 1.
All the 4 lines showed as per the confirmation date order.
But the schedule line numbers are not as per the above order.
For example,
Schedule line number ----- delivery date ----- Confirmed qty
1. 09.04.2014 0
3. 14.04.2014 60
2 16.04.2014 30
4 18.04.2014 10
On what basis this schedule numbers getting determined? Is there any standard procedure ?
Why schedule line numbers not inline with the confirmed date?
Let me know if you need more information.
Thank you.
Regards,
Rakkimuthu CHi,
Schedule line number is the number that uniquely identifies the schedule line .
Use When an item has more than one schedule line, the system automatically assigns a unique number to each line. The number is displayed in the details screens for schedule lines.
Note The schedule line number serves internal purposes and does not, for example, determine the sequence of schedule lines in the overview screen. The schedule lines on the overview screen are sorted by date.
The schedule line number will get created automatically by the system. I hope this will clarify your doubt. Thanking you. -

I would like to know the line number of the current caret position in a JEditorPane. The getLineOfOffset(int offset) method in JTextArea offers exactly what I want. How come there's no method to find out about line number in JEditorPane?
As a workaround, I copied the Swing code from the JTextArea.getLineOfOffset method and used it in my class which extends from JEditorPane. It seems to work fine, but it feels like a bad hack. Will the JTextArea code always work in JEditorPane? Any alternatives? I just think that it's tedious and inefficient to deal with StringTokenizer or manually searching for new line charactors on CaretEvent's.
public int getLineOfOffset(int offset) throws BadLocationException {
Document doc = getDocument();
if (offset < 0) {
throw new BadLocationException("Can't translate offset to line", -1);
} else if (offset > doc.getLength()) {
throw new BadLocationException("Can't translate offset to line", doc.getLength()+1);
} else {
Element map = getDocument().getDefaultRootElement();
return map.getElementIndex(offset);
}It's not a hack. Any document used with a Swing text component is supposed to have the same basic element structure, i.e., a default root element whose children represent logical lines. It's just that with some kinds of documents, like HTML, line numbers don't really mean anything. But JTextArea is hard-coded to use a PlainDocument, which means a logical line always represents a paragraph (or a line of code, or something meaningful), so it made sense for it to provide those convenience methods.

Line number in a *.class file, please help, advanced language guys
dear all,
i use c++ to open a *.class file and try to read line number of code in the file, i have 2 questions:
1. i read line number in a method successfully, but i can not understand the meaning of start_pc, following are one of those data, please explain:
s = start_pc,n = line_number
s , n
0 , 123
8 , 125
23 , 126
29 , 127
34 , 129
38 , 130
2. i can not find where the class's line number are, i.e. class start line and class end line, or field's line number.
does these info exist inside a *.class file?
thx for any lightjdb gets line number of fields from class file, not
source file definitely.I'm not really sure how you tested this, but here's my test, and JDB definitely gets its listing from the source file.
First, I created and compiled class Tester:
public class Tester
public static void main( String[] argv )
throws Exception
Tester x = new Tester();
System.out.println(x.toString());
int x;
int y;
private Tester()
x = 0;
y = 1;
}Then, I ran this in JDB. Note lines 16 and 17 in the output from "list":
H:\Workspace>jdb Tester
Initializing jdb ...
stop in Tester.mainDeferring breakpoint Tester.main.
It will be set after the class is loaded.
runrun Tester
Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.Throwable
>
VM Started: Set deferred breakpoint Tester.main
Breakpoint hit: "thread=main", Tester.main(), line=12 bci=0
12 Tester x = new Tester();
main[1] list
8 {
9 public static void main( String[] argv )
10 throws Exception
11 {
12 => Tester x = new Tester();
13 System.out.println(x.toString());
14 }
15
16 int x;
17 int y;
main[1] quit
Tester@b82368Then I edited the source file. Again, look at lines 16 and 17:
H:\Workspace>jdb Tester

It will be set after the class is loaded.

13 System.out.println(x.toString());
14 }

16 int a;
17 int b;

Find Line Number in Text Member
I would like to drop in a line of text after a specific phrase in a text member. To find the right place to drop the text, I must first determine the line number the specific phrase text is located. Now, I can use a REPEAT to walk through each line until it is found, but there must be a more elegant way. The code "Offset" is great for finding the first character number of the specific phrase, but I don't know how to glean the line number from that.
Currently this is how I do it...
repeat with xLineCount = 1 to 100
if textDoc.line[xLineCount] contains "<specific text phrase>" then
put RETURN & RETURN & "<new text pasted>" after textDoc.line[xLineCount]
exit repeat
end if
end repeat
Can anyone give me a more elegant approach this?A more elegant approach might be to use a regular expression, but I'm not sure I understand your requirements well enough to make a sensible recommendation.
You could try the following JavaScript handler and invoke it like:
tMember.text = jsReplace(tMember.text, "<specific text phrase>", "<specific text phrase>" & RETURN & RETURN & "<new text pasted>")
function jsReplace(inStr, strFind, strReplace){
// error check input
if(typeof(inStr) != "string") { return inStr; }
if(typeof(strFind) != "string") { return inStr; }
if(typeof(strReplace) != "string") { return inStr; }
// search-and-replace
re = new RegExp(strFind, "g");
return inStr.replace(re, strReplace);
However, this will place the pasted text immediately after the search phrase and not at the end of the line. It is possible to do this with a regular expression, but I'd have to dust off my copy of Friedl's "Mastering Regular Expressions" to craft it for you and I don't have either the time or inclination at present. -

Replacing text in Text File in a perticuler line number
Hi,
I have a text file where values will be stored like
user=alex;checkout=no;checkin=yes;
user=rexy;checkout=yes;checkin=yes;
user=nik;checkout=no;checkin=no;
user=philip;checkout=yes;checkin=no;
user=nex;checkout=yes;checkin=no;
I know the line number of user nik(no=3) how can i replace that full line only with new values
or a particular part (checkout=yes).According to each event i have to change a specific part in text file for that user .
Thanks
[email protected]Read the first two lines and write them to a new file. Write the new values for line 3 to that new file. Read the rest of the lines and write them to that new file. Close all the files, delete the old file, rename the new file.

hello all,
i have an ALV report requirement like this,
on the initial screen i have displayed(for a given agreement number like in ME33K )
in the selection screen i have taken agreement number as EKPO-EBELN.
purchase document number item number short text target quantity net price
5400000019 1 xxx 1.000 304300.00
2 xxxx 1.000 500000.00
the above fields i have taken from EKPO table.....
and on double clicking the item number i have displayed
line number service number short text quantity units gross price quantity released
1 swr10 xxxx 2.00 kg 500 2
2 swr11 xxxx 5.00 EA 500 2
the above fields i have taken from ESLL (esll-extrow, esll-srvpos, esll-ktext1 , esll-menge etc......)
this i have done by passing EBELN to ESLH and getting PACKNO and passed this PACKNO to ESLL.
now my question is i need to display Purchase order, PO Item , Order Number ,entry sheet quantity ,entry sheet price ,invoice quantity, invoice price
against each line number above.....
from which table do i need to take these fields.....
please guide me....
thankq....Thanks Andra,
The problem is the multiple invoices is for non goods receipt item so there will be no delivery.At the time of creating a PO the GR is not checked so there will be no delivery .
Also this setting is for invoices which are comming from Vendors.But if we are genrating the invoices manually it is not blocking those invoices.Also i there is nowhere mentioned in Incomming invoice to set tolerence for incomming invoice.Are you talking about Vendor tolerences?
Thanks in advance
