Error: Could not initialize class sun.nio.fs.UnixCopyFile

#1

I have a page that used to successfully upload an image file, and now does not.

I am getting the following error:
error: Could not initialize class sun.nio.fs.UnixCopyFile

Code is:

<cfset dir_upload = "/home/mysitefolder/public_html/temp" >
<cfparam name="form.fileUpload" default="">

<cfif len(trim(form.fileUpload))>	
	<cftry>
        <cffile action="upload"
        fileField="fileUpload"
        destination="#dir_upload#" 
        nameconflict="overwrite" >
        
		<cfscript> 
        	fileSetAccessMode("#dir_upload#/#File.ServerFileName#.#File.ServerFileExt#", "644"); 
        </cfscript> 
        
        <p>View it here: <cfoutput><a href="/temp/#File.ServerFileName#.#File.ServerFileExt#" target="_blank" >#File.ServerFileName#.#File.ServerFileExt#</a></cfoutput></p>
      
	   	<cfcatch type="any" >
        	<cfoutput>error: #cfcatch.Message# #cfcatch.Detail#</cfoutput>
        </cfcatch>
    </cftry>

What I can quickly get from googling around is the following. Please excuse if you’ve already done that. It’s just the first steps I’d do in your case:

  • Is the directory you are uploading the file existent? If not then create it, and make sure when copying no directory creation has to be envolved.
  • Also check if Tomcat has write permission to the folder you’re uploading the file.

Thanks Andreas, after all that, it appears that a permissions fix resolved this issue. Not sure how those permissions had changed, but glad to have this solved.

Thanks!

I have filed a bug to improve the error message / feedback when this happens, it’s way too cryptic
