problem with JasperViewer

[skuda]

I am executing from my app JasperViewer for every .jprint file created in my application, if i leave the isExitOnClose=true it closes my application when i close the window and if i use isExitOnClose=false many times after the first usage (the first ever work) i get this errors:

sun.awt.X11.XException: Cannot write XdndAware property at sun.awt.X11.XDnDDropTargetProtocol.registerDropTarget(XDnDDropTargetProtocol.java:79) at sun.awt.X11.XDropTargetRegistry.registerDropSite(XDropTargetRegistry.java:554) at sun.awt.X11.XWindowPeer.addDropTarget(XWindowPeer.java:1633) at sun.awt.X11.XComponentPeer.addDropTarget(XComponentPeer.java:1509)at java.awt.dnd.DropTarget.addNotify(DropTarget.java:493) at java.awt.Component.addNotify(Component.java:6666) at java.awt.Container.addNotify(Container.java:2567) at javax.swing.JComponent.addNotify(JComponent.java:4685) at java.awt.Container.addNotify(Container.java:2578) at javax.swing.JComponent.addNotify(JComponent.java:4685) at java.awt.Container.addNotify(Container.java:2578) at javax.swing.JComponent.addNotify(JComponent.java:4685) at java.awt.Container.addImpl(Container.java:1068) at java.awt.Container.add(Container.java:927) at net.sf.jasperreports.view.JasperViewer.<init>(JasperViewer.java:145) at net.sf.jasperreports.view.JasperViewer.viewReport(JasperViewer.java:416) at net.sf.jasperreports.view.JasperViewer.viewReport(JasperViewer.java:380)

I am launching for now every time with java commandline to get a new jvm and can trust it but it is slow obviously slow to start a new jvm every time.

Hi, I have the same problem.

The application run to Linux Ubuntu v.9.04 or v. 10.04 with JasperReport 3.7.1 and I had the problem AFTER the update of JRE from v. 1_6_22 to 1_6_24.

The problem is random, pushing the button the viewer sometimes start and view the report, sometimes I get this error:

sun.awt.X11.XException: Cannot write XdndAware property at sun.awt.X11.XDnDDropTargetProtocol.registerDropTarget(XDnDDropTargetProtocol.java:79) at ecc...

I have tried to update to JasperReport v. 4.0.1, but the result is the same.

Is there a solution or workaround?

Regards

Marco

 Not that i know, but i have the same problem in my development machine (Arch Linux 2.6.37 x86_64 with java 1.6.0_24 64 bits) that in the production machine (Debian Linux 2.6.32-5-686 with java 1.6.0_22 32 bits).

 Strange, I'm not experienceing that on Debian with 64 bit 1.6.0_24, but have a customer experiencing it on 1.6.0_23 (RedHat). 

There's a bug report on Netbeans: http://netbeans.org/bugzilla/show_bug.cgi?id=193917

Hi all!

Would you please explain here the solution? The page at Oracle (yeah... not Sun...) says "This bug is not available."

Thanks in advance,

 Hi!

   The workaround it is to launch java with -DsuppressSwingDropSupport=true parameter in command line.
