Jasper Report stopped working

[paola.sartene]

Can anyone hel me, please?

Sometime ago I developed and deployed succesfully a report with two subreports to our platform.
I did not work anymore on the reports till yesterday when I made some minor changes, from that
moment the report generation stopped working (also if I revert the report to the previous version).
The problems are as follow:

1. When I try to get a preview the Eclipse plug-in claims that there is a parameter that "must be compiled"
   before previewing the report (?)
2. When I deploy the three Jasper files I get the exception invalid stream header: 3C3F786D, while all
   the subreports in the main report point to the Jasper version, the compiled file.​

Can anyone help me plase? I am going crazy!

Now I tried something simple like the following one and got the same message at report preview: "Some parameters are present that should be compiled in order to create the report".
