Hello, I'm a newbie using jasper reports server, and I'm trying to deploy a home server to practise and learn the technology. I'm using jasperserver 5.5.0 over a mysql database. It's working acceptably except for some problems when I'm trying to schedule jobs. First of all, when I try to put the job, I get this error from server ( HTTP 500 Internal Server Error - "java.io.EOFException: No content to map to Object due to end of input"), although job is correctly scheduled and throws itself in time without problem. The stacktrace in log is as following at org.codehaus.jackson.map.ObjectMapper._initForReading(ObjectMapper.java:2766) at org.codehaus.jackson.map.ObjectMapper._readValue(ObjectMapper.java:2682) at org.codehaus.jackson.map.ObjectMapper.readValue(ObjectMapper.java:1308) at org.codehaus.jackson.jaxrs.JacksonJsonProvider.readFrom(JacksonJsonProvider.java:419) In addition, when I return to see the list of scheduled jobs for current report, I get another Internal Server Error which is caused for java.lang.NoClassDefFoundError: com/sun/xml/bind/DatatypeConverterImpl$CalendarFormatter at com.sun.xml.bind.DatatypeConverterImpl._printDateTime(DatatypeConverterImpl.java:360) at com.sun.xml.bind.DatatypeConverterImpl.printDateTime(DatatypeConverterImpl.java:356) at javax.xml.bind.DatatypeConverter.printDateTime(DatatypeConverter.java:598) every time there is still an scheduled job. Even more, when I load a list of scheduled jobs, it doesn't mind if there is any of them, I get an HTTP 404 when trying to view the /options page from the report,being referrer page the following jasperserver/scheduler/main.html. I hope anyone could help me solving this problem because I can't manage my scheduled jobs nowadays. Thank you all in advance.
