JAVA代码调用birt报表
JAVA调用BIRT设置的SCRIPT数据集
数组方式：
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;
List方式
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
importPackage(Packages.com.jshx); count=0; users=reslut;
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<=users.size()){
row["columnFirstName"] = users.get(count).getFname();
row["columnLastName"] = users.get(count).getLname();
row["columnPhoneNumber"]= users.get(count).getPhone();
count++; return true; }
return false;
