Hi, I don't have the file ReportExecutionJob.java. Also, my filepath is different. I have /opt/jasperreports-server-cp-4.0.0/samples/java-webapp-sample/jasperserver-ws-sample-jar/src/main/java/com/jaspersoft/jasperserver/sample. Under the sample directory, I have WSClient.java, ReportExecutionHyperlinkProducer.java, ImageServerlet.java, and ContentResourceDataServlet.java. How do I go about and remove the hyphen from the filename when adding a timestamp.
