[question about subreport sample]

Folks, I'm looking at the samples, and i was checking out the subreports sample, and either i don't understand how it works, or something is missing or both. The zip file contained the following files: MasterReport.html MasterReport.jrxml MasterReport.pdf Shouldn't there be a jrxml or something for the subreport part? basically i can't figure out where the subreport text is coming from. e.g. in the left column it says, "Products ordered by people in <City>", and on the right side it says, "Addresses in <city>", but i don't see this text in the MasterReport.jrxml. Thanks, Nilesh

 

 

Nilesh,

 

for the "products", the text "Products ordered by people in <City>" is coming from "MasterReport.jrxml" (line # 195) and "ProductReport.jrxml". A similar situation holds for the "addresses".

the text is coming from the subreports,

[How to report on nested bean collection]

To whom it may concern,

 

I need to report on a nested bean collection in my report, which is essentially a standard letter with a table of data.

 

The following outline resembles my letter:

 

<<START TEMPLATE>>

NAME

ADDRESS

DATE

 

SALUTATION

 

LETTER BODY

 

TABLE DATA

 

SIGNATURE

<<END TEMPLATE>>

 

My Letter body is represented as a Java bean and contains a List of Java beans representing the table data.

 

The Letter and Table beans are fairly standard.

 

eg.

 

import java.util.List;

public class Letter {

private String name;

private Address address;

private List tableList;

public String getName() {};

public void setName( String newName ) {};

public Address getAddress() {};

public void setAddress( Address newAddress ) {};

public List getTable() {}; //List of Table objects

public void setTable( List newTable ) {};

}

 

public class Table {

private Date issueDate;

private String description;

public Date getIssueDate() {};

public void setIssueDate() {}

public void setDescription( newDescription ) {}

public String getDescription() {};

}

 

I am using a JRBeanCollectionDataSource as my data source for the jasper report template.

 

While I can query "fields" from the Letter using bean access notation (eg. letter.name), I cannot query fields from the beans in the nested Table List using bean access notation (eg. letter.table[index]).

 

I may be missing something here regarding how jasper works with (bean) data sources.

 

Am I able to query a bean and nested List using the same bean collection data source ? Or, should I be using a master report template for the letter body and a sub-report template for the table data, each with their own bean data source ?

 

I have yet to find any examples (with the jasper distribution) or elsewhere that cover this problem.

 

I think my query is loosely related to the previous posting in this forum, "How to link each subreport with diff datasrc" at

"http://www.jasperforge.org/index.php?option=com_joomlaboard&Itemid=&func=view&catid=9&id=393#393"

 

Assistance most welcome.

 

 

Thanks.
