I have Jasper Server 6.1.1 and Jasper Studio 6.1.1. Here's my scenario: I tried publishing a report from studio to server, and when I opened up the report on the server web application, the report came up as blank with a message saying 'The report is empty.'. After a bit of googling, I found that my report needs to be published to the server with a data source in order for it to be viewed on the sever web application. So now, when I publish, I check 'Local Data Source'. I select a Datasource JDBC, give it a name ("test", for example) and I then "Import from Jaspersoft Studio", selecting the Data Adapter that I use for data in my report. However, when I click finish, I get this error: org.apache.http.client.HttpException: Internal Server Error at com.jaspersoft.studio.server.protocol.restv2.RESTv2ExceptionHandler.handleException(RESTv2ExceptionHandler.java:72) at com.jaspersoft.studio.server.protocol.restv2.ARestV2ConnectionJersey.toObj(ARestV2ConnectionJersey.java:52) at com.jaspersoft.studio.server.protocol.restv2.RestV2ConnectionJersey.addOrModifyResource(RestV2ConnectionJersey.java:515) at com.jaspersoft.studio.server.protocol.ProxyConnection.addOrModifyResource(ProxyConnection.java:314) at com.jaspersoft.studio.server.publish.Publish.publishResources(Publish.java:198) at com.jaspersoft.studio.server.publish.Publish.publish(Publish.java:67) at com.jaspersoft.studio.server.publish.wizard.Publish2ServerWizard$3.run(Publish2ServerWizard.java:302) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) Any help would be great!
