Java String [][] Array into Jasper

[ziden]

 Hello there.

     Im having an issue about passing an two dimensional array to jasper so he can build up some sort of table with it. Its a normal table, with 2 variables that represent lines/columns. The array is filled during the Java process and its sent to Jasper as a Class into a JRBeanCollection. What ive needed to do is reading the lines size of the array, then draw some sort of table representing the array positions. Is that possible ? Witch one would be the better way of acomplishing that ? Ive seem some methods on Jasper but im not sure on how to, that would be the CrossTable and the Sub-Report for instance.

   Thanx for any help.

 

PS: Im using IReport 1.2.6 for this task. I know its an Older Version, but its what we gotta use here to work it out. Thanx.

If your data are organized as String[][], a better approach is to use a JRTableModelDataSource instead of a JRBeanCollection. Also, if you don't need special headers and/or row/column calculations, you can draw a simple table just using the <detail/> band, and setting your detail band and report elements with appropriate x, y, width, height and border properties. Be careful that report elements do not overlap.

For more informations about, take a look at the datasource sample, and then try to run it.

Hope this helps,
