When I try and run my code that generates a PDF file using JasperReports class I get the following error in the console: java.lang.UnsupportedClassVersionError: net/sf/jasperreports/engine/JRDataSource (Unsupported major.minor version 49.0) Can someone help me get this resolved?

Can someone help me to get an iReport to accept an array as a parameter from a JSP call. Then use that array as my datasource for the detail band.

What I need is the code to put into the Image Expression to convert text to barcode using the barbecue.jar.

What exact code goes into the Image Expression to create a Code39 barcode?

Can anyone help me out here? I really need to get a barcode on my PDF output.

I am sending a string value as a parameter to my report. I need the value displayed as a barcode. I can get it to work with the JR viewer but when creating a PDF output the value reverts back to string. I don't see any barcode font in the PDF Font listing for the field property.

In my report I have two date columns. I need a column that will show the difference in days between these two date columns. Please help.

Yes, only the table name will change.

Is there a way to send a string as a parameter and use it as the Report Query String. I would like to have one report that could pull from one of four data sources depending on the string I send as a parameter.

I still have not found a solution for this. Surely someone can help me with parsing collection elements at the report field level or tell me the better way to send an array to a report.

I really could use some help on this.

I am send a list to my report as a collection. How or what is the syntax in the report field to display the items in the list? This may not even be how to do what I need to do. I need to display a report with many calculated values. I could create a parameter for each one, then from my servlet send the value for each. I would like to create an multi-dimensional array of values and send that as one parameter to the report. Then parse the array into the necessary fields. This is a no-data report.

Still really need some help with this.

Yes. I am sending three prams to the report. I have tested this every way I know how and no success. I changed the two parameters(sd1 and fd1) in the SQL statement to hard coded strings and ran the report with two fields to display the two parameters I am sending and it looks like the values are getting to the report okay. However, tt looks like the SQL statement doesen't interpret the parameters(sd1 and fd1) correctly. Thanks for helping me figure this out.

Is anyone able to give any suggestion for this?
