jasperadmin generate blank report screen

I have upgrate centos 6.4X64bit  to 6.5 X64 bit.

I have already import catalog into jasper server 4.5 but when i click on report from jasper admin its generate blank page for enter input parameter screen.

Can you please let me know jasper 4.5 is supporting centos 6.5 or not?Because i can not see even input parameter screen from jasper admin.

Even I am not able to upload new jrxml file from jasper admin.

When i try to upload jrxml file it generate blank page.

Please get back to me as soon as possible.

Thanks,Zarna
