Thanks for the help, j. I'm not sure this information relates to my specific problem though. I'm talking about the plugin for iReport that comes with the JasperServer Open Source edition. It asks for this information:Server Information: Name, JasperServer URLAccount: Username, PasswordWhen I submit the information, an empty jasperserverplugin.xml file is created in my .ireport directory and this error occurs:[color=#000080]*****************************java.lang.NoSuchMethodError: java.util.Properties.storeToXML(Ljava/io/OutputStream;Ljava/lang/String; )V at com.jaspersoft.jasperserver.irplugin.IRPlugin.saveConfiguration(IRPlugin.java:249) at com.jaspersoft.jasperserver.irplugin.gui.RepositoryExplorer.jButtonAddServerActionPerformed(RepositoryExplorer.java:2224) at com.jaspersoft.jasperserver.irplugin.gui.RepositoryExplorer.access$3200(RepositoryExplorer.java:80) at com.jaspersoft.jasperserver.irplugin.gui.RepositoryExplorer$33.actionPerformed(RepositoryExplorer.java:602) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$ForwardActionEvents.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.AWTEventMulticaster.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)*****************************[/color]At first I thought that I was entering the wrong information, but now I think that the plugin doesn't work, or maybe the JasperServer installer didn't install it correctly.
