Hi!!!

I have a little problem on Alfresco + Share 4.2.b
When I create or upload a txt file, I can't see any preview in Share. I get the message "The preview could not be loaded ", and if I check my logfiles (alfresco.log), I find this:

17:39:37,125 ERROR [org.springframework.extensions.webscripts.AbstractRuntime] Exception from executeScript - redirecting to status template error: 00080385 The content node was not specified so the content cannot be streamed to the client: classpath*:alfresco/templates/webscripts/org/alfresco/repository/thumbnail/thumbnail.get.js
org.springframework.extensions.webscripts.WebScriptException: 00080385 The content node was not specified so the content cannot be streamed to the client: classpath*:alfresco/templates/webscripts/org/alfresco/repository/thumbnail/thumbnail.get.js
‍‍‍

The point is, with all other documents the preview works!
I'll be very grateful to anyone who could help me.

Thanks in advance!

Regards,

E.

Hi Enrico,

could you tell me the size of your text file?

The "WebPreview" (default flash reader) has a size limit, if your files is bigger it does not generate the preview.
You can find settings here "<ALF_HOME>\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\repository.properties" (version 4.0.e)

# text -> pdf using PdfBox (txt=text/*) 10M takes about 12 seconds
content.transformer.PdfBox.TextToPdf.maxSourceSizeKBytes=10240

# pdf -> swf using Pdf2swf 1M takes about 30 seconds.
# Using a value of 1.25M (a bit larger that the txt or xlsx) used to create
# the pdf on the way to swf to avoid the second part of a transform failing
content.transformer.Pdf2swf.maxSourceSizeKBytes=1152

# txt -> pdf -> swf 1M (pdf is about the same size as the txt)
# Need this limit as transformer.PdfBox txt -> pdf is allowed up to 10M
# unlike transformer.OpenOffice and transformer.JodConverter which
# also only allow 1M text
content.transformer.complex.Text.Pdf2swf.maxSourceSizeKBytes=1024
