HELP URGENT:; Splitting strings in servlets

hi ...
I am trying to access the below servlet from another servlet in iplanet . I have to access a file and arrange the '|' delimited data in the file in a table format like in html ...
I have used my own function inside the servlets which splits a string based on character ...But I always get
Internal error: exception thrown from the servlet service function (uri=/servlet/ReportsDataServlet): java.lang.NullPointerException, Stack: java.lang.NullPointerException
at ReportsDataServlet.split(ReportsDataServlet.java:82)

The sample code is shown below....I get the same error when i tries with stringokenizer as well....Pls help me fix this.....

d deeply appreciate if soeone could take a look at the code and tell me exactly where i am going wrong ..... Its URGENT ...
Thx
klv

But there is the while statement which filters null
values..Which is useless in your case, because you proceed to change the value of st to something else which you don't check for null.
At any rate, what you have to do is this:
1. Look at the stack trace to find the line number where the error occurs.
2. Look at that line in your code.
3. Look at each object variable in that line. Find out how it became null and fix that.

Urgent help reqd in string tokenizing

hi all,
i want to count the number of commas in the screen,
ths is my code
import java.util.*;
class TokenizerTest
     public static void main(String[] args)
String str= new String("REMOVE_STR,01,6403,40,143,990,410,,,11,ATTN PAT COLEMAN,, ,,,N,,,,,,,,,,,NC,,,,,");
     StringTokenizer st= new StringTokenizer(str,",",false);
     int i=0;
     while(st.hasMoreTokens())
          System.out.println(st.nextToken()+" Val :"+i);
          i++;
     System.out.println("Value of i"+i);
System.out.println("Count is " +st.countTokens());
}but its notgiving the proper count... those commas whcih are not separated by spaces orcharacter, it desn't count like" ,," it won't count theese commas it works fine when commas are separated by spaces or charachters.
what is the solution for this?.. plz help me its urgent
Thanx in advance
Deepali

countTokens() should have been called before the while loop.
so, System.out.println("Count is " +st.countTokens()); should be place before the while loop or create
a local int variable to store the count and use the variable in the
System.out.println("Count is " + count);
The reason why you're not getting the proper count is this:
    In the while loop..you use nextToken()..when this method is called..countToken() method count the total
    number of token left; therefore...after the while loop..countToken() will always return ZERO.
    you should use the String split(String regex) function, if you are using the jdsk 1.4 or higher.
public static void main(String[] args) {
    String str= new String("REMOVE_STR,01,6403,40,143,990,410,,,11,ATTN PAT COLEMAN,, ,,,N,,,,,,,,,,,NC,,,,,");
    String s[] = str.split(","); // require jdk 1.4
    // NOTE:   the String "a,,b"      - two commas return
    //    s[0] = "a"
    //    s[1] = "";    // empty string
    //    s[2] = "";    // empty string
    //    s[3] = "b";
    for (int i = 0; i < s.length; i++)
        System.out.println("Value of i = " + s);
System.out.println("Count is = " + (s.length - 1) );

Function module to split strings

Hi,
I have a string value ' DBTABLE-FIELDNAME'. I need to split this into 2 strings - The first one is the database table name and the second one is the fieldname. So, the character '-' is the point where the split needs to be done. How can this be achieved. Any FM that I could use?
Thanks for your help!

Divyaman Singh Rawat

Use FM 'STRING_SPLIT'
REPORT ZEXAMPLE.

            P_DEM.
CALL FUNCTION 'STRING_SPLIT'

          STRING    = P_STR
     IMPORTING
          HEAD      = V_HEAD

Send large string between servlets in different domain

Hi,
I need to send a large string from servlet in an web application to a
servlet in another web application. Those two application are in
different domains. I can't send the string as request parameter,
bacause string is too large. I can't send as request attribute either,
because attribute will lost during redirect to another domain.
Any solutions? Thanks for any help.

do set/getAttribute at the ServletContext level which is unique for a particular webapplication. from 1st application u can access the 2nd one using , getServletConfig().getServletContext().getContext("/uripath") which gives you the ServletContext handle of the other application and you can do getAttribute of this.

Split string into new column

Hi All,
Hoping you are able to help.
I have a table of approx 16 items that I need to split,
EG:
CUSTOMER ACCEPTANCE - HAS BEEN DECLINED - DO NOT APPLY TO ACCOUNT
CUSTOMER ACCEPTANCE - HAS BEEN ACCEPTED - APPLY TO ACCOUNT
CUSTOMER ACCEPTANCE - PENDING DECLINE - ESCALATION REQUIRED - RAISED IN PORTAL
ESCALATION - RAISED - PENDING
ESCALATION - NOT RAISED - STILL TO BE PROCESSED
I need to Keep the first two sections, eg CUSTOMER ACCEPTANCE - HAS BEEN DECLINED in one column, and split off the remaining, eg DO NOT APPLY TO ACCOUNT into a new TEMP table to insert as a column into an existing table.
With little SQL experience, I am having difficulties as they are all of different lengths / criteria etc. Some have 3 hyphens whilst others have 4+
Is anyone able to help point me in the right direction with this request? I will be greatly appreciated.
Kind Regards,
BTMMP

If you're trying to do this all in a SQL query or stored procedure, then you'll probably get better results on the SQL Server forums. However, if you're working with a PowerShell or VBScript that's doing the work, you're in the right place.
Here's one example of how you could do what you're describing. By the way, what do you want to do with the string "CUSTOMER ACCEPTANCE - PENDING DECLINE - ESCALATION REQUIRED - RAISED IN PORTAL"? Should that be split into "CUSTOMER ACCEPTANCE
- PENDING DECLINE" and "ESCALATION REQUIRED - RAISED IN PORTAL", or "CUSTOMER ACCEPTANCE - PENDING DECLINE - ESCALATION REQUIRED" and "RAISED IN PORTAL"?
(In other words, should the script only split off whatever's after the final hyphen, or should it grab the first two pieces of text and split off everything else?)
Here's an example in PowerShell which assumes that you want to separate out all text after the final hyphen in a string. It uses a regular expression, though you could accomplish the same thing with Split, Join and Trim operations, if you prefer.
$string = 'CUSTOMER ACCEPTANCE - HAS BEEN ACCEPTED - APPLY TO ACCOUNT'
if ($string -match '(.*?)\s*-\s*([^-]*)$')
$split = $matches[1], $matches[2]
else
$split = $string, ''
Write-Host "Original String: $string"
Write-Host "First Text : $($split[0])"
Write-Host "Second Text : $($split[1])"

Need some help with the String method

Hello,
I have been running a program for months now that I wrote that splits strings and evaluates the resulting split. I have a field only object (OrderDetail) that the values in the resulting array of strings from the split holds.Today, I was getting an array out of bounds exception on a split. I have not changed the code and from I can tell the structure of the message has not changed. The string is comma delimited. When I count the commas there are 26, which is expected, however, the split is not coming up with the same number.
Here is the code I used and the counter I created to count the commas:
public OrderDetail stringParse(String ord)
OrderDetail returnOD = new OrderDetail();
int commas = 0;
for( int i=0; i < ord.length(); i++ )
if(ord.charAt(i) == ',')
commas++;
String[] ordSplit = ord.split(",");
System.out.println("delims: " + ordSplit.length + " commas: " + commas + " "+ ordSplit[0] + " " + ordSplit[1] + " " + ordSplit[2] + " " + ordSplit[5]);
The rest of the method just assigns values to fields OrderDetail returnOD.
Here is the offending string (XXX's replace characters to hide private info)
1096200000000242505,1079300000007578558,,,2013.10.01T23:58:49.515,,USD/JPY,Maker,XXX.XX,XXX.XXXXX,XXXXXXXXXXXXXXXX,USD,Sell,FillOrKill,400000.00,Request,,,97.7190000,,,,,1096200000000242505,,,
For this particular string, ordSplit.length = 24 and commas = 26.
Any help is appreciated. Thank you.

Today, I was getting an array out of bounds exception on a split
I don't see how that could happen with the 'split' method since it creates its own array.
For this particular string, ordSplit.length = 24 and commas = 26.
PERFECT! That is exactly what it should be!
Look closely at the end of the sample string you posted and you will see that it has trailing empty strings at the end: '1096200000000242505,,,'
Then if you read the Javadocs for the 'split' method you will find that those will NOT be included in the resulting array:
http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)
split
public String[] split(String regex)
Splits this string around matches of the given regular expression. This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
Just a hunch but your 'out of bounds exception' is likely due to your code assuming that there will be 26 entries in the array and there are really only 24.

String.class without split(String regex)

hello,
This is my problem:
I am using eclipse with j2sdk1.4.2 which
implement
the clase String.class with
method replaceAll(String regex, String replacement) and
method split(String regex)
PAth: home_j2sdk1.4.2/jre/lib/rt.jar 25.762kb
In this way:
String columns[] = line.split("\t");
for (int i=0; i<columns.length; i++)
ws.addCell(new Label(i,row,columns.replaceAll("\"","")));
I move the code above to websphere Application Developer 5.1.2
which use Home_Websphere/eclipse/jre/lib/rt.jar 8.827 kb
this jar in yours String.class not contains the
method replaceAll(String regex, String replacement) and
method split(String regex)
I need to find the use my code above with that methods,
what i need to do ???
possible,i need to find the source to String.java of j2sdk1.4.2
which implement the methods, but where ???
or there is another way to do it ???
Any help is greatly appreciated.

If websphere is supposedly 1.4 compatible, arethey
"allowed" to leave out methods from the JFC? Not sure what the JFC is, but no, they would not be
allowed to leave out any methods.
JFC - Java Foundation Classes. I think they started calling what might be considered the Java Core the JFC when they first added Swing to the distribution. Maybe the term is no longer used.

Split String FM

Hello,
Does anyone know a standard string FM that split string at an absolut place and consider if the N place is blank or not ?
My meaning is likely:
str = 'test one two three'.
I would like to split str at the 10th place but because it's in a middle of word split it in the 8th place ..
str1 = 'test one'
str2 = 'two three'
and not
str1 = 'test one t'
str2 = 'wo three'
I know that VB has few methods like that, I'm hope abap has it also ..
Thanks in advance,
Rebeka

Hi Rebeka,
                Please check the following code. This would help. FM 'TEXT_SPLIT' does it correctly.
DATA: text(50) TYPE c VALUE 'test one two three',
text1(20) TYPE c,
text2(20) TYPE c.
CALL FUNCTION 'TEXT_SPLIT'
EXPORTING
    LENGTH             = 10
    TEXT               = text
   AS_CHARACTER       =
IMPORTING
   LINE               = text1
   REST               = text2
check sy-subrc = 0.
write :   text1 ,
          text2.
Reward points if useful.

Need help urgently with OS X and Windows 7

I need help urgently.
I installed Windows 7 on my macbook pro with OS X Lion. After installing Windows7, I accidently converted the basic volumes to dynamic volumes and now i can't even boot to OS X.
Please help me how to recover my OS X Lion. If I have to delete Windows and bootcamp partitions, it is OK.
I just want to get back my OS X bootable.
Thanks

I could see OS X and Windows partitions if I hold down Option key before changing the partitions to Dynamic partitions from Basic in Windows 7.
Now can't see OS X partiton and only see Winodws partition but when I tried to boot onto Windows7 , I got BSOD and macbook pro restart.
Please help
The usual reason for the OSX partition to be invisible under these circumstances is that it has been trashed by Windows.
Do you have a backup?
