Hi again,
well it seems the source code wasn't that involved, just a nice wrapper
mostly over the file formats. It doesn't seem to have built-in JDBC
connection support, so I wrote a modified version that takes an Object
for dataSource and then dictates the proper JasperFillManager.FillReport
method depending on a JRDataSource or Connection object. That aside, I
could use some advice into applying the FillAndExport method :
/**
* export the report.
*
* @param inputResource the input resource (report template file
".jrxml")
* @param format the output format
* @param parameterMap the parameter map
* @param dataSource the datasource. Either a JDBC SQL Connection or
JRDataSource object
* @param outputStream the output stream
*/
public void fillAndExport(Resource inputResource, ExportFormat format,
Map parameterMap, Object dataSource, OutputStream outputStream)
{
JasperPrint jasperPrint = fillReport(inputResource,
parameterMap, dataSource);
export(jasperPrint, format, outputStream);
}
In older code at my company (JSP-Servlet based), we typically build the
parameterMap, hand load the inputResource in a File object, and then
define the format/content-type in the HTTPResponse and connect the
HTTPResponse's outputStream into the export method. At this point the
intended results are displayed.
To mirror this, I found the Response service in Tapestry, and use the
getOutputStream(contentType) method, setting the appropriate
content-type string in the call. Can I expect this to work as I intend
(displaying/triggering the browser through this stream)?
I'm calling the function like this:
public void onSuccessFromRepForm(){
Map parameterMap = loadParameters(reportTitle);
Connection conn = null;
try{
conn = Report.getConnection();
rs.fillAndExport(new ContextResource(cimpl,reportTitle+".xml"),
formMode, parameterMap, conn, os);
}catch (Exception e){
System.out.println("Caught exception while trying to execute the report
fillAndExport service method.");
throw new TapestryException("Issue executing report", e);
} finally {
if(conn != null){
try {
conn.close();
} catch (SQLException e) {
System.out.println("Could not close the JDBC connection!!");
}
}
}
}
cimpl is an injection of the Tapestry Context service, formMode is a
page property, and os is the loaded Response OutputStream. When I try to
test this (this was before I made the JDBC Connection change) I get the
following Exception from the ChenilleKitReportsModule (:
Exception constructing service 'ReportsService': Error invoking service builder
method
org.chenillekit.reports.ChenilleKitReportsModule.buildReportsService(Logger,Map) (at ChenilleKitReportsModule.java:43)
(for service 'ReportsService'): Parameter configuration was null.
From the module:
public static ReportsService buildReportService(Logger logger, Map<String,
Resource> configuration)
{
return new ReportsServiceImpl(logger,
configuration.get(ReportsService.CONFIG_RESOURCE_KEY));
}
I'm assuming this is because I don't have a line in my AppModule where i
add to the configuration a mapping for "jasperreports.properties"
(resolution of ReportsService.CONFIG_RESOURCE_KEY), but I'm also not
sure what this is supposed to be mapping to.
Things break worse when I use my own extended version including JDBC

The part that stands out to me is:
**Caused by: java.lang.NoClassDefFoundError:
org/apache/commons/collections/map/LRUMap**
My best guess is that this is a result of the JasperReports 3.7.4
dependency, as I isolated this to only occur when code dependent on this
library is in the application. When I use the Chenillekit-Reports
dependency instead, this exception goes away. A bit interesting... this
exception doesn't actually affect my application since I can use the
Chenillekit-Reports jar, but it seemed worthwhile to mention the
incompatibility.
When I use the ChenilleKit-Reports dependency though, I get the same
exception in my AppModule as ChenilleKitReportsModule from a null in the
buildReportsService method.

Hi,
I have to integrate some Jasper reports into a Tapestry web app and I
came across Chenillekit-reports, which seems like it might be a
solution. I'm having a hard time finding any useful documentation
related to it though. Are there any web resources available explaining
implementation or should I just work my way through the source code?
I'm assuming this is the best implementation of JasperReports into
Tapestry at this point in time, but if there are other options I'm all
ears.

Rich
