pumaking Posted September 28, 2009 Share Posted September 28, 2009 Hi,I've got a problem with a UNC image path which comes from the database. I work with these absolute paths from the database in other reports without any problem. But now I got the following error:com.jaspersoft.jasperserver.api.JSExceptionWrapper: Byte data not found at location : \\server\share\folder\file.jpg When I copy the path in the error message and paste in in windows explorer the file is shown without any problem. I also tried to manually add the file to the report as a static image to see if there could be a problem with the file itself. This works perfectly. So I thought if there is perhaps an empty space in the path which comes from the database. So I put the image expression together from the foldername and the filename which also comes from the database:"\\server\share\folder\" + $F{Imagename}With that I get the following error:com.jaspersoft.jasperserver.api.JSExceptionWrapper: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ ) value = (java.lang.String)("\\server\share\folder\" + ((java.lang.String)field_Imagename.getValue())); //$JR_EXPR_ID=12$ So I tried:"\\server\\share\\folder\\" + $F{Imagename}Now the error is again (because the backslash appears only one time in the beginning):com.jaspersoft.jasperserver.api.JSExceptionWrapper: Byte data not found at location : \server\share\folder\file.jpg My next try was this one:"\\\server\\share\\folder\\" + $F{Imagename}And now again this error:com.jaspersoft.jasperserver.api.JSExceptionWrapper: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ ) value = (java.lang.String)("\\\server\share\folder\" + ((java.lang.String)field_Imagename.getValue())); //$JR_EXPR_ID=12$ How can I solve this problem?
