Using Java beans DS for subreports

[tush]

Hi All,

I want to create a report using few subreports. The data source I want to use is java beans. But the problem here is iReport allows only one java bean as a data source. I have MainRptBean java bean for main report and SubRptBean java bean for subreport. This means different beans for each report. I tried running both report separately, these are working fine but as soon as this subreport is added to main report I can not see the contents of the subreport when I run main report. I want to know how to set up different java bean data source for subreport.

 

The example code is as follows. This below example is using just one subreport but actually I want to use lots of subreports in my actual program.

 

This is the java bean data source for main report. Main report is fetching the data from this bean.

Code:

import java.util.ArrayList;
import java.util.List;

public class MainRptBean {

    private String name;
    private String age;
   
      /**
       * @return Returns the age.
       */
      public String getAge() {
            return age;
      }
      /**
       * @param age The age to set.
       */
      public void setAge(String age) {
            this.age = age;
      }
      /**
       * @return Returns the name.
       */
      public String getName() {
            return name;
      }
      /**
       * @param name The name to set.
       */
      public void setName(String name) {
            this.name = name;
      }
      
      public static List generateCollection()  {
    	MainRptBean mRtp = new MainRptBean(); 
    	mRtp.setAge("25"«»);
    	mRtp.setName("John"«»);
  		
  		List list = new ArrayList();
  		list.add(mRtp);
  		return list;
  	}
}

 

This is the java bean data source for subreport. I want subreport to use the data from this java bean.

Code:

[code] import java.util.ArrayList; import java.util.List; public class SubRptBean { private String subject; private String marks; /** * @return Returns the marks. */ public String getMarks() { return marks; } /** * @param marks The marks to set. */ public void setMarks(String marks) { this.marks = marks; } /** * @return Returns the subject. */ public String getSubject() { return subject; } /** * @param subject The subject to set. */ public void setSubject(String subject) { this.subject = subject; } public static List generateCollection() { SubRptBean sRtp = new SubRptBean(); sRtp.setMarks("99"«»); sRtp.setSubject("English"«»); List list = new ArrayList(); list.add(sRtp); return list; } }

 

Please let me know if the proble m is not clear to anybody.

 

Thanks in advance.
