I have gone through http://www.opal-consulting.de/apex/f?p=20090928:4: but I am not using it.why don't you want to use the integration kit? Is there a problem with it?
I believe that your solution includes a web application and some pl sql packages. I feel that web services are simpler to use and hence I prefered this solution.Well, yes and no. Here is a view of the architecture: http://www.opal-consulting.de/downloads/JasperReportsIntegration/images/screenshot.151.png .
I havnt downloaded the package but I believe that the code must be wrapped hence I will not be able to appretiate the beauty of the solution.
I believe that you must have found a way out of this trouble since you have a solution in place. I humbly request you to suggest a possible way to parse SOAP web service response of JasperWell, I cannot help you here. If you want to learn to handle SOAP request, then please do. But I don't like the complicated stuff ;). Thus I have implemented a simple url interface which does the job nicely. All you get returned is a blob containing the generated report in the desired format .... very simple :).
