Java calls the script dataset set by Birt.

Step 1: Define Java and class (see the attachment below)
Step 2: define a list
Step 3: Enter
Count = 0;
Cf = new packages. User. contactlistfactory ();
C = Cf. createcontactlist ();
In the dataset event of the Birt report (close), enter
Cf = NULL; C = NULL;
In the dataset event (FETCH) of the Birt report, enter
If (count <= C. Length-1 ){
Row ["columnfirstname"] = C [count]. getfname ();
Row ["columnlastname"] = C [count]. getlname ();
Row ["columnphonenumber"] = C [count]. getphone ();
Count ++; return true ;}
Return false;

Two Java class codes in step 1 are issued:
A: Package user;
Public class contact {
String fname;
String lname;
String phone;
Public contact (string fname, string lname, string phone ){
This. fname = fname;
This. lname = lname;
This. Phone = phone;
}
/*
*
* @ Return returns the fname.
*/
Public String getfname (){
Return fname;
}
/**
* @ Param fname the fname to set.
*/
Public void setfname (string fname ){
This. fname = fname;
}
/**
* @ Return returns the lname.
*/
Public String getlname (){
Return lname;
}
/**
* @ Param lname the lname to set.
*/
Public void setlname (string lname ){
This. lname = lname;
}
/**
* @ Return returns the phone.
*/
Public String getphone (){
Return phone;
}
/**
* @ Param phone the phone to set.
*/
Public void setphone (string phone ){
This. Phone = phone;
}
}


B:
Package user;
Public class contactlistfactory {
Public contact [] createcontactlist (){
Contact [] C = new contact [5];
C [0] = new contact ("Stavros", "kounis", "2310886269 ");
C [1] = new contact ("Dimitris", "kounis", "2310888270 ");
C [2] = new contact ("Dimitris", "Adamos", "2310998417 ");
C [3] = new contact ("Nikos", "koufotolis", "2321013770 ");
C [4] = new contact ("Yan", "Liang", "13824745919 ");
Return C;
}
}

Note: After the release, place the classes generated by the two Java classes in
C:/Eclipse/plugins/org. Eclipse. Birt. Report. viewer_2.1.0.N20060628-1351/Birt/WEB-INF/classes/user directory,
User is the package during development.

Write a Java Project
The code for calling the preceding report is as follows:

Package user;
Import javax. Swing. joptionpane;
Import user. executereport;
Public class reporttest {
Public static void main (string ARGs []) {
Try {
Executereport mreport = new executereport ();
Mreport.exe cutereport ();
} Catch (exception e ){
E. printstacktrace ();
}
/* System. Out. println ("people's solutions of China ");
Joptionpane. showmessagedialog (null, "Chinese people's solutions ");
System. Exit (0 );
*/
}
}
