In conluence unable to preview the PDF thumbnail. People want to have thumbnail view for pdf files.
Please find the attached screenshot for your reference. The attached screenshot thumbnail shows preview for PPT file but doesn't for the PDF file.
I have no problem displaying PDFs as links or thumbnails - I can even toggle between either way in the edit screen - refer my screen shots in this posting
You must have a bad file format or a problem in the configuration of your Confluence
Try another PDF file from another source?
I can assure you we have lots of PDF and Word documents that display directly as thumbnails
It looks like we can't display PDF/Word attachments in this forum as thumbnails - I just tried to load another test and it doesn't give the option of how to display it
But you might want to try downloading this PDF and try loading that to your system just to see if it is anything to do with your file
What happens when you try to load a Word document to your system?
The issue I'm experiencing may be the same. In Confluence 6.0.1 PDF thumbnails fail to load for all users except the first user created for this instance of Confluence. The thumbnails either show up as a broken link or as it appeared in this thread's example, depending on the browser that I use. Given that this works for the user that first created the wiki, I assume this is some sort of permission issue, but I've been unable to identify it. When I follow the image location (not the link to the document, but the actual thumbnail's URL), I receive a Confluence "Page Not Found" error:
The page you were trying to reach could not be found. This could be because:
After logging all and poking around a bit more, I see that my issue is centered around a HibernateTemplate error:
execute Not closing pre-bound Hibernate Session after HibernateTemplate
This is occurring during a SQL query that is pulling file details on the thumbnail from the DB. Below is the SQL query that should be executed at that time:
select attachment0_.CONTENTID as CONTENTI1_12_0_, attachment0_.HIBERNATEVERSION as HIBERNAT2_12_0_, attachment0_.TITLE as TITLE4_12_0_, attachment0_.LOWERTITLE as LOWERTIT5_12_0_, attachment0_.VERSION as VERSION6_12_0_, attachment0_.CREATOR as CREATOR7_12_0_, attachment0_.CREATIONDATE as CREATION8_12_0_, attachment0_.LASTMODIFIER as LASTMODI9_12_0_, attachment0_.LASTMODDATE as LASTMOD10_12_0_, attachment0_.VERSIONCOMMENT as VERSION11_12_0_, attachment0_.PREVVER as PREVVER12_12_0_, attachment0_.CONTENT_STATUS as CONTENT13_12_0_, attachment0_.PAGEID as PAGEID14_12_0_, attachment0_.SPACEID as SPACEID15_12_0_ from CONTENT attachment0_ where attachment0_.CONTENTID=? and attachment0_.CONTENTTYPE='ATTACHMENT'
