title: Passing in content when generating JasperServer report using the REST API
body: <p>I'm working on a project that aims to replace our current PDF generator with JasperReports Server. The plan is to use the REST/HTTP API to reach a high level of abstraction between the systems.</p>
  
  <p>Optimally, we do not want to let JasperReports Server pull the data from the database, since this would bypass the existing logging and authorization in the calling application's architecture. Instead, we'd like to start with extracting the content in the calling application, and then pass that content to JasperReports Server.</p>
  
  <p>We've done quite a bit of investigating, and the lack of relevant results indicates that this is not how you typically use JasperReports Server. The input parameters in the tutorials we've found are typically scalar values (integers, booleans or strings), and not complex structures or objects. Furthermore, it seems like more or less every sample assumes that you want to let JasperReports Server connect to a database.</p>
  
  <p>If it's possible to pass in complex structures (like an array of maps, where some map elements are arrays or maps themselves), what's the best practice for doing this? I have no idea of how such a structure should be formatted in the request body. Is the SOAP API a better fit?</p>
  
  <p>If this is not at all how you should design a JasperReports Server solution, what alternative products/solutions are more suitable?</p>
  
  <p>Thanks in advance for any input.</p>
