第一步：定义一下JAVA,class(看后面附件)
第二步:定义一个LIST
第三步：在BIRT报表的DATASET事件中(open)中输入
count = 0;
cf = new Packages.user.ContactListFactory();
c = cf.createContactList();
在BIRT报表的DATASET事件中(CLOSE)中输入
cf=null;
c=null;
在BIRT报表的DATASET事件中(FETCH)中输入
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;

第一二步的两个JAVA类代码发下：
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;
}
}
注：发布后将两个JAVA类产生的CLASS 放在
C:/eclipse/plugins/org.eclipse.birt.report.viewer_2.1.0.N20060628-1351/birt/WEB-INF/classes/user 目录下，
USER是开发时的包
经过发上步骤，再写一个JAVA PROJECT
调用上述报表代码如下
package user;
import javax.swing.JOptionPane;
import user.ExecuteReport;
public class Reporttest {
public static void main(String args[]) {
try {
ExecuteReport mreport = new ExecuteReport();
mreport.executeReport();
}catch ( Exception e ) {
e.printStackTrace();
}
/*System.out.println("中国人民解");
JOptionPane.showMessageDialog(null,"中国人民解");
System.exit(0);
*/
}
}

}
IReportRunnable design = null;

在eclispe 3.2的PATH BUILD中加入
BIRT 的com.ibm.icu_3.4.4.1 .JAR BIRT
的engineapi.JAR BIRT 的coreapi.JAR BIRT 的JS.JAR
