how to set up a subreport using an xml datasource

[ronatartifact]

I am trying to draw a purchase order with a few subreports to display things like Bill to and Ship to addresses as well as item lines.

I can not figure out how to specify the connection of the data source from the main report to the sub reports in the right way

It can not be that complicated but I have not been able to figure it out from the documentation that I have found.

 

Thanks

Ron

XML Datasources work on the XML standards so you simply need to point your datasource at the root of your XML datafile. Then move the cursor position to the correct node to output the data.

Also you need to add the tag name to the Description property of the Field element.

Your datasource to get the data and make it all work will depend on the complexity of your XML datafile and your xPath statement, Which is all garbled above. upload a file!

Suggest you have a look at the example that ships with jasperReports and have a look at xPath tutorial here :

Luck!

I actually found a sample chapter from one of the books on iReports that actually described a good part of the process.

http://books.google.ca/books?id=GeLCEnT1VpMC&pg=PA157&lpg=PA157&dq=ireports+jrxmldatasource+example&source=bl&ots=abW5BGl9G2&sig=ncpr7vEI2QZJfOLe3gJSN5d7vE4&hl=en&ei=dn2pSuvhHoqlnQecjvgY&sa=X&oi=book_result&ct=result&resnum=7#v=onepage&q=&f=false

 

I also found an out of date manual which was helpful.

http://ireport.sourceforge.net/cap7.html  was the most helpful document but it glossed over the key information about how to link up the fields between the  sub-reports and the main report.
By a bit of testing and reading between the lines, I figured out what the actual code had to be.
If it had 2 more sentences and two code fragments, it would have solved my problem at first reading.

The sample chapter (first reference above) supplied the information that the last reference lacked.

I have attached my working code and data for anyone who finds this thread and wants a working solution.

The report is still underconstruction but the bits that are there, work.

ronatartifact,

 

The Google Books link is interesting. (It's out of date compared to what's available on jaspersoft.com, but I don't think that piece hasn't changed.)

 

The scribd link is the entire copy of a copyrighted book. Using 233 of 233 does fall under fair use principles. It's a clear copyright violation. Would you mind removing the link to it?

 

Regards,
Matt
