Problem reading a string:Plz help

hi gurus
I am reading some files (in a loop written by some other program). I am reading them line by line and I tokenize each line by space using split function.
split(" ");
In resultant string array, somewhere I found NULL or nothing , for example, I print all tokens and it prints like this
?penguins/nns? // I print ?on both sides to check any spaces
?march/nnp?
?? // now here is problem.. both ? combined..nothing between them
I have checked the file.. this problem occurs where there are multiple spaces between tokens of a line...if I remove others and keep one space it works..
Now I want to implement a check in program i.e. where there is SPACE or NULL, I should not process it but It does not work
Please help

Thanks a Lot Sir
There is another problem that I am facing now..
I am using this statement
while ( (rec=dis.readLine() ) != null )to read a line from a file. What I have observed is that if there is a gap between two line then it stops executing file there and even does not go for further files..
Can you identify the problem or better solution
thanks

I think you need to create the build.properties file, as documented in:

Problems with the Strings Urgent Help needed

I have a unique problem. I have to retrieve a particular value from a String. I tried using String tokeniser but in vain. I cannot use java.util.regex package to match the expressions as the version of java on the client m/c is 1.1.8 and they are not ready to upgrade the same.
The string From which I have is a very long one running into more than 100 lines which can vary from case to case all I know is to retrieve the value which is just in front of "TestValue" which occur only once in the String Can Anybody suggest a bettter alternative.
Thanx.
ebistrio

StringTokenize on TestValueHow would you suggest that was done?
As I understand it StringTokenizer tokens = new StringTokenizer(string, "TestValue"); would not tokenize on the string "TestValue" but on any of the characters 'T', 'e', 's', 't', 'V', 'a', 'l' or 'u'. This is a common java pitfall in my opinion due to bady named parameters (I feel it should be called "delims" not "delim") or in other people's opinion due to bad parameter type (should be a char[] not a string).
A clearer explanation of the problem would help.

I am facing a new problem with xml schema, plz help me

Hi @,
I am facing a problem with xml schema validation. Below is my code.
public void initialize(String cfgFileName) {
try {
try {
DOMParserWrapper parser = (DOMParserWrapper)Class.forName("dom.wrappers.DOMParser").newInstance();
parser.setFeature( "http://apache.org/xml/features/dom/defer-node-expansion",true );
parser.setFeature( "http://xml.org/sax/features/validation",true);
parser.setFeature( "http://xml.org/sax/features/namespaces",true );
parser.setFeature( "http://apache.org/xml/features/validation/schema",true );
parser.setFeature( "http://apache.org/xml/features/validation/schema-full-checking",true );
Document document = parser.parse(cfgFileName);
System.out.println("Vijay .. code .. damar\n");
}catch (org.xml.sax.SAXParseException spe) {
} catch (org.xml.sax.SAXNotRecognizedException ex ){
} catch (org.xml.sax.SAXNotSupportedException ex ){
} catch (org.xml.sax.SAXException se) {
if (se.getException() != null)
se.getException().printStackTrace(System.err);
else
se.printStackTrace(System.err);
}catch (Exception e) {
System.out.println("Caught unknown exception : \n");
e.printStackTrace(System.err);
System.out.println("Vijay .. code .. success\n");
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
//docBuilder.setErrorHandler(myErrorHandler);
cfg = docBuilder.parse(new File(cfgFileName));
cfg .getDocumentElement ().normalize ();
} catch (Exception e) {
e.printStackTrace();
In the above code I am parsing the xml file and i am doing schema validation. Schema validation is proper and it is validating correctly. Only problem is that, It is validating and showing error correctly correctly but it is not catching that error.
For clear understanding I am printing one statement before parsing and after parsing.
SYSTEM.OUT.PRINTLN("Vijay .. code .. damar\n") this is before parsing
SYSTEM.OUT.PRINTLN("Vijay .. code .. success\n") this is after parsing
Here what is happening means, It is validating correctly and showing error :
[Error] nw_layout-new.xml:800:97: Datatype error: Value 'y' does not match regular expression facet 'yes|no'..
Vijay .. code .. damar
Vijay .. code .. success
Here it is showing error and still continueing not catching.
Plz give solution for this.
Thanks

hi,
i'm using cookies in my application
1) in file1.jsp i'm setting the cookie as -----
Cookie cook11 = new Cookie("noOfRows","10");
response.addCookie(cook11);
2) in file2.jsp i'm retrieving that value as-----
ServletUtilities is user defined class
ServletUtilities su = new ServletUtilities();
Cookie[] cook = request.getCookies();
String strnoOfRows = su.getCookieValue(cook,"noOfRows","");
3) in file3.jsp i'm reseting the value of cookie as-----
ServletUtilities su = new ServletUtilities();
Cookie[] cook = request.getCookies();
Cookie cook1 = su.getCookie(cook,"noOfRows");
cook1.setValue(strnoOfRows1);
now the problem is after changing the cookie value by running file3 after that if i run file2 and check the cookie value it won't change as setted in file3.
These files are running in browser(IE/Netscape) only .
rather the application is web based.
when i start the application file1 runs then file2, which contains value of cookie same as set in file1...........
i'm providing an opportunity to client to change the cookie value in file3...................
now i want that if user run file2 again further it should show the changed value.
as per someones suggestion
i changed my file3 as...........
ServletUtilities su = new ServletUtilities();
Cookie[] cook = request.getCookies();
Cookie cook1 = su.getCookie(cook,"noOfRows");
cook1.setValue(strnoOfRows1);
response.addCookie(cook1);
BUT SILL MY PROBLEM HAS NOT SOLVED .......................PLZ TELL SOME SOLUTION.
-----Amita

Create a new cookie and overwrite the old cookie instead of attempting to change it's value.
     Cookie cook1 = new Cookie("noOfRows",strnoOfRows1);
     cook1.setPath("/myApp");
     response.addCookie(cook1);

Oracle to Mysql character set conversion problem!!! PLZ HELP

Hi Experts,
I have created a database link from Oracle 10g to Mysql 5.
I have installed Oracle Gateway 11g for this purpose.
When i retreive the data from sql plus the text is displayed as question marks.
Oracle 10g Database character set is WE8MSWIN1252
Mysql character set --->latin1
Character set of ODBC connector for mysql is latin7
Character set in the parameter file of HS folder is WE8MSWIN1252When i retrieve data from sql developer the text is fine(as i think it directly takes the character set of target) but
when i login from sqlplus i get question marks!
Appreciate your help,
regards

thank you for replying damorgan,
my previous two threads in the "heterogeneous Connectivity" forum were for different issues, one was to enquire as to how i could connect from oracle to mysql(which i have marked as answered), the other is for error when i get when i tried accessing data(which i am still facing on my office machine ).
I followed the steps from these two threads and was able to successfully connect to mysql on my personal PC at home, but faced some problem with text not displayed so i created this thread.
I had created another thread similar to this in the globalisation support as i was facing issue with the character sets in a heterogenous setup, so wasen't clear as to which forum would be suitable for this issue.
My apologies to everyone if this has offended you.

HT4489 I can't import an Outlook vcard that is 7.3k in size. It sends me an error message saying it had a problem reading the card. Help.

Using the iCloud help screen I tried to import an Outlook contact in vcard format. iCloud tells me it is having trouble reading the vcard (which is 7.3k in size). Can someone help overcome this problem? Thanks.

The message says: "The payment method has been denied, try another method"
I'm living in the same country and city since I was born, so I don't think the location is the problem.
And yes, I paid with the card a meal in Burguer King today. And nothing more.

Realtek HD Audio Problems... Plz Help!

I'm currently a temporary DJ for my friend, who's a professionalk DJ, and our party starts in an hour or so. My MacBook, the one I bought last Thanksgiving, the audio on windows won't work. I had Realtek HD Audio, the driver that was on my Leopard dvd. I have always kept my sound muted on XP, so maybe this could be a problem? But the audio won't play, and I've tried playing different mnedia players, Microsoft's WMP and Apple's iTunes. I tried playing a clip from YouTube, all won't play with sound. Any ideas or help??? Thanks.

oops. sorry, I just experimented, I plugged in my iPod earbuds into my laptop, and played the clip. The familiar click sound of the volume adjust was heard, and I pulled the earbuds out and beautiful audio came out on the speakers! So maybe its just the fact that I havent used the speakers on my laptop much. Thanks for looking anyway, and problem solved!

If you can solve this problem u r genius - plz help me

Others have run into similar things. See if one of these links offers any help and if not try to google for FacesServlet.java:209:

My guess is that something may have gotten corrupted (second link) unless someone changed something from the time it was working to the time it stopped working.

During Foreach read another foreach - PLZ HELP!

Hi all powershell gurus out there.
I have a foreach which opens a URL from URLListl.txt and doing a
Measure-command on them. The result from Measure-command writes to event-log.
In another text file i have country list, like:
USA
Canada
Brazil
and so on....
I want in write eventlogs Message to read from this Text file and write it with the Measure-command result in Message part of the eventlog.
The below is my script which works fine but it creates two entries for each URL.
function Measure-Site
$URLListFile = "C:\yourname\URLList.txt"
$URLList = Get-Content $URLListFile -ErrorAction SilentlyContinue
Foreach ($Uri in $URLList)
$Time = Measure-Command {
C:\yourname\MainScript.ps1}
$Time.TotalSeconds
$countrycode = (Get-Content c:\yourname\URLListcountry.txt)
foreach ($SiteCode in $CountryCode)
$LogFileExist = Get-EventLog -list | Where-Object { $_.LogDisplayName -eq "Scriptcheck" }
if (! $LogFileExist)
New-EventLog -LogName "Scriptcheck" -Source "Scripts"
if ($Time.Totalseconds -lt 25)
Write-EventLog -LogName "Scriptcheck" -Source "Scripts" -EntryType information -EventId 100 -Message " $SiteCode `nTotal Time: $Time"
elseif ($Time.Totalseconds -gt 25)
Write-EventLog -LogName "Scriptcheck" -Source "Scripts" -EntryType warning -EventId 101 -Message " $SiteCode `nTotal Time: $Time"
if (Get-Process -name iexplore -ErrorAction SilentlyContinue)
Stop-Process -Name iexplore

Noobish question on strings-plz help

Whats wrong with this code?
public String name(){
          String str="hi";
          if(str.equals("hi"))
               return str;
Why is it saying "This method should return a result of type string"?
Regards.

public String name(){
    String str="hi";
    if(str.equals("hi")) {
        return str;
    // if above if statement is false code gets to here
    // where is the return statement?
}The compiler doesn't give a shit about evaluating the if statement to see that it can only be true. All the compiler looks at is that when the if statement is false there is no return statement.
