Hi, I'm getting "The preview cannot be loaded form the server." (sic) when I try to view the large preview image of a PNM/JPEG2000 file in Share. The small preview in the list file shows up fine. Large previews of other objects, from PNGs to PDFs, are working fine. I'm running Labs version D on RedHat Linux with the Alfresco-included Tomcat 6, JRE 1.6. My JAVA_OPTS are "-Xms256m -Xmx512m -Xss96k -XX:MaxPermSize=128m -server". I do have jasper installed. The large preview did work in Labs version C, but stopped working in Labs version D. I haven't tried it with version E. The first time I got this error, looking at a pnm that I had uploaded with Labs version C, I saw this in the error log:java.awt.image.RasterFormatException: Data array too small (should be 189125 ) at

Since then, however, I've seen no errors in the error log post-processing. I haven't been able to get this error to come up again. I wonder if it has to do with being unable to load the preview cached with version C. On uploading a new .pnm file, I got the following errors in the error log. I don't get these errors when uploading non-PNM files.java.nio.channels.ClosedChannelException at sun.nio.ch.SocketChannelImpl.ensureWriteOpen(Unknown Source) at sun.nio.ch.SocketChannelImpl.write(Unknown Source) at org.alfresco.jlan.smb.server.nio.ChannelPacketHandler.writeBytes(ChannelPacketHandler.java:133) at org.alfresco.jlan.smb.server.nio.TcpipSMBChannelHandler.writePacket(TcpipSMBChannelHandler.java:167) at org.alfresco.jlan.smb.server.PacketHandler.writePacket(PacketHandler.java:219) at org.alfresco.jlan.smb.server.SMBSrvSession.sendResponseSMB(SMBSrvSession.java:1579) at org.alfresco.jlan.smb.server.SMBSrvSession.sendAsynchResponseSMB(SMBSrvSession.java:1750) at org.alfresco.jlan.smb.server.notify.NotifyChangeHandler.sendChangeNotification(NotifyChangeHandler.java:813) at org.alfresco.jlan.smb.server.notify.NotifyChangeHandler.run(NotifyChangeHandler.java:1038) at java.lang.Thread.run(Unknown Source)java.nio.channels.ClosedChannelException at sun.nio.ch.SocketChannelImpl.ensureWriteOpen(Unknown Source) at sun.nio.ch.SocketChannelImpl.write(Unknown Source) at org.alfresco.jlan.smb.server.nio.ChannelPacketHandler.writeBytes(ChannelPacketHandler.java:133) at org.alfresco.jlan.smb.server.nio.TcpipSMBChannelHandler.writePacket(TcpipSMBChannelHandler.java:167) at org.alfresco.jlan.smb.server.PacketHandler.writePacket(PacketHandler.java:219) at org.alfresco.jlan.smb.server.SMBSrvSession.sendResponseSMB(SMBSrvSession.java:1579) at org.alfresco.jlan.smb.server.SMBSrvSession.sendAsynchResponseSMB(SMBSrvSession.java:1750) at org.alfresco.jlan.smb.server.notify.NotifyChangeHandler.sendChangeNotification(NotifyChangeHandler.java:813) at org.alfresco.jlan.smb.server.notify.NotifyChangeHandler.run(NotifyChangeHandler.java:1038) at java.lang.Thread.run(Unknown Source)
Let me know what you think… config problem, or software bug? If it's a bug, I'll try version E before I report it.
