Communication between Jasper and another application

Question

I have a Jasper report server (installed on www.example.com ) and a separate Java / JSP application (installed on www.example.net ), and I use various report generation options.

Option 1 (current working solution)

My current working solution is that the user logs into the Java / JSP application and selects the report. The application creates an XML representation of the report, which it saves as fileNameXML , and then sends it to the Jasper report server using the following code:

  <IFRAME height="600" width="1000" src="https://www.example.com/jasperserver/flow.html? _flowId=viewReportFlow&standAlone=true&_flowId=viewReportFlow& ParentFolderUri=%2Freports& reportUnit=%2Freports%2FExample_Report_2&j_username=user& j_password=password& net.sf.jasperreports.xml.source=https://www.example.net/<%=fileNameXML%>"> </IFRAME> 

(Note that even if I pass the username and password in the URL, security is not compromised because filenameXML is created using String fileName = UUID.randomUUID().toString() + fileExt; )

Option 2

I connect the Jasper Reports server directly to the SQL Server database at www.example.net and create reports this way. The disadvantage of this approach is that (a) I would need to configure all users in Jasper reports (b) I would need to pass parameters consciously so that each user can only access their own data (c) I only have access to the database, not to the calculations of my application.

My perfect solution

However, I would really like to have access to the calculations of my application through Jasper and bypass the entrance to my application.

One of the advantages of this is that my application does not yet have proper mobile access, and users can download the Jasper Mobile Application and access reports from there.

This will include the following:

• User is registered in Jasper
• User selects report
• Jasper calls my application with certain parameters
• The application creates an xml file
• The application returns a link to this file
• Jasper shows report

What is the best way to achieve this?

Answer 1

I think the best way to do this is:

• Create a URL in your application that is accessible at any time and does not require a login. If you use Spring or any other structure, stating that this would be good, as I could show you how to do this.

There are many ways to trick this cat. Let me know what technologies you use, and perhaps we can start from now on. We have complied with the requirement that you have now.

Thanks.
