Question

What web development frameworks natively support JasperReports?

Consider the following form as an example:

<form name="report" method="post">
  <input type="hidden" name="REPORT_PATH" value="reports/Names" />
  <input type="hidden" name="REPORT_FILE" value="List" />
  <input type="hidden" name="REPORT_FORMAT" value="pdf" />
  <input type="hidden" name="REPORT_EMBED" value="false" />

  Name: <input type="text" name="report_Name" value="" /><br />
  Date: <input type="text" name="report_Date" value="" /><br />
  <input type="submit" name="View" value="View" />
</form>

The framework would pass the report_ parameters to JasperReports, which in turn runs reports/Names/List.jasper, and then sends a PDF attachment to the browser.

In general, the framework can:

• Configure the report (i.e., the hidden REPORT_ variables)
• Use a web FORM for setting report parameters (i.e., the report_ variables)
• Handle configuring database connection, report execution, etc.

I don’t care about the technical minutia on how the integration works, as long as it is simple.
