swing not getting initialized when the DISPLAY is not set

I have a batch programme which will load the Spreadsheet into database..

When the DISPLAY is set and X11 window server is running, there is no issue in reading the spreadsheet and loading into database without lauching UI.

But if the display is not set, then there is an issue... Any ideas over this ?? Why does a batch programme requires DISPLAY and X11 window server to be set when there is no need of UI to launch....

Code pasted below :

24 public class Spreadsheet extends com.f1j.swing.JBook
25 {
26 private int failedSheetNum = 0;
27
28 public Spreadsheet()
29 {
30 super();
31 setup();
32 }


Exception is thrown at line 30 :

GIT-CHECK-ATTR(1)						    Git Manual							 GIT-CHECK-ATTR(1)

NAME
git-check-attr - Display gitattributes information SYNOPSIS
git check-attr [-a | --all | attr...] [--] pathname... git check-attr --stdin [-z] [-a | --all | attr...] < <list-of-paths> DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname. OPTIONS
-a, --all List all attributes that are associated with the specified paths. If this option is used, then unspecified attributes will not be included in the output. --cached Consider .gitattributes in the index only, ignoring the working tree. --stdin Read file names from stdin instead of from the command-line. -z Only meaningful with --stdin; paths are separated with a NUL character instead of a linefeed character. -- Interpret all preceding arguments as attributes and all following arguments as path names. If none of --stdin, --all, or -- is used, the first argument will be treated as an attribute and the rest of the arguments as pathnames. OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF <path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either: unspecified when the attribute is not defined for the path. unset when the attribute is defined as false. set when the attribute is defined as true. <value> when a value has been assigned to the attribute. EXAMPLES
In the examples, the following .gitattributes file is used: *.java diff=java -crlf myAttr NoMyAttr.java !myAttr README caveat=unspecified o Listing a single attribute: $ git check-attr diff org/example/MyClass.java org/example/MyClass.java: diff: java o Listing multiple attributes for a file: $ git check-attr crlf diff myAttr -- org/example/MyClass.java org/example/MyClass.java: crlf: unset org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing all attributes for a file: $ git check-attr --all -- org/example/MyClass.java org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing an attribute for multiple files: $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java org/example/MyClass.java: myAttr: set org/example/NoMyAttr.java: myAttr: unspecified o Not all values are equally unambiguous: $ git check-attr caveat README README: caveat: unspecified SEE ALSO
