Hi, First of all, I'm new to Java and Java Applets. I didn't know about JasperReports Applets till now and saw its potential to my projects. However, I can't make it work. I attached the Applet I'm currently working. It's a modified copy of the EmbeddedViewerApplet.java. Sorry if I made a mess. Also attached HTML I used. Basically, I need to be able to control some functions in Applet through Javascript specially the print function. But errors shows on console log. (Shown below) I can view the report nicely using the applet so I assume the JasperPrint object sent by the server is fine. Here's what fixes I already tried but to no avail. 1. Signed all jar files using jarsigner 2. I marked Option 1 on my code using JasperPrintManager, see what happened below 3. I marked Option 2 using JRPrinterAWT, also noted below 4. Upgraded to jasperreports-applet 4.0.2 hoping for some bugfixes Code:=============================================Option 1:ERROR Showing when using JasperPrintManagerNote: Access to printer does NOT prompt--------------------------------------------- java.lang.ExceptionInInitializerError at JRViewerApplet$1.run(JRViewerApplet.java:109) at java.lang.Thread.run(Unknown Source)Caused by: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.print) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPackageAccess(Unknown Source) at sun.plugin2.applet.Applet2SecurityManager.checkPackageAccess(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at net.sf.jasperreports.engine.JasperPrintManager.<clinit>(JasperPrintManager.java:419) ... 2 more=============================================Option 2:Error showing when using JRPrinterAWTNote: Access to printer prompts, and answering 'Yes' to allow access.--------------------------------------------- java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/print/JRPrinterAWT$1 at net.sf.jasperreports.engine.print.JRPrinterAWT.printPages(JRPrinterAWT.java:143) at net.sf.jasperreports.engine.print.JRPrinterAWT.printPages(JRPrinterAWT.java:84) at JRViewerApplet$1.run(JRViewerApplet.java:110) at java.lang.Thread.run(Unknown Source)Caused by: java.lang.ClassNotFoundException: net.sf.jasperreports.engine.print.JRPrinterAWT$1 at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) ... 4 more

Hi, I just upgraded from JasperServer 3.5 to 3.7 to 4.0 as stated in documentation. After upgrading, report headers are not included when exporting to XLS. Included here is my xlsExportParameters as stated in applicationContext.xml I also attached a sample jrxml file that has the issue. Hope someone can help. Thanks in advance! Code:<property name="detectCellType" value="true"/><property name="onePagePerSheet" value="false"/><property name="removeEmptySpaceBetweenRows" value="true"/><property name="removeEmptySpaceBetweenColumns" value="true"/><property name="whitePageBackground" value="false"/><property name="ignoreGraphics" value="false"/><property name="collapseRowSpan" value="false"/><property name="ignoreCellBorder" value="false"/><property name="fontSizeFixEnabled" value="true"/><property name="maximumRowsPerSheet" value="65000"/><property name="xlsFormatPatternsMap" ref="formatPatternsMap"/>
