Strange preview problem with docs saved via SPP

jmcooper — Wed, 03 Nov 2010 17:02:29 GMT

Running Alfresco Community 3.4a with Ubuntu 10.04 64bit server.Share is working fine and the document viewers are working fine when I upload files via the Upload function (word, pdf, etc)But when I create or modify a document in MS Word 2003 via the SharePoint emulator interface there is no preview

First thing to check is that the mimetype is application/msword instead of application/octet-stream or anything else.

I seem to recall a recently-fixed bug in the SPP code around this area.

Thanks,
Mike

Thanks Mike.

Yes the MIME type is incorrectly set to "Octet Stream"

I don't have any control over that from the MS Word (SPP) level (I don't think). Manually editing via the Share I/F resolves, but … what's the best way to patch this?

Thanks,

John

Here's the JIRA issue: https://issues.alfresco.com/jira/browse/ALF-5098

The suggested fix (to be confirmed) is:

org.alfresco.module.vti.web.actions.VtiIfHeaderAction-> doPut() should be changed: 

Old code: 
———————————————————- 
// updates changes on the server 
try 
{ 
     writer.putContent(req.getInputStream()); 
} 
——————————————————— 

New code: 

———————————————————- 
// updates changes on the server 
try 
{ 
     String mimetype = mimetypeService.guessMimetype(documentName); 
     writer.setMimetype(mimetype); 
     writer.putContent(req.getInputStream()); 
} 
——————————————————— ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks,
Mike

Sorry Mike,

I haven't been able to verify this. I'm confused by where to find the code to change:

You said:
org.alfresco.module.vti.web.actions.VtiIfHeaderAction-> doPut()

I'm looking around here:
root@alf3:/opt# ls -l /opt/alfresco-3.4.a/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/module/org.alfresco.module.vti
total 16
drwxr-xr-x 2 root root 4096 2010-10-27 14:15 context
-rw-r–r– 1 root root 1117 2010-10-27 14:03 modifications.install
-rw-r–r– 1 root root 262 2010-06-09 14:02 module-context.xml
-rw-r–r– 1 root root 278 2010-10-27 14:03 module.properties

Can you point me to something more specific ???

Hi all,

Sorry to raise the post again but I have the issue with my fresh Alfresco 3.4.b installation …

When I upload the document, Share seems not to be able to generate the thumbnail and the preview (Store + Sites) of my doc file (Word2003).

I have checked the file Mimetype in file properties : "Type MIME: Microsoft Word". Moreover, the "Edit Online" option doesn't appear (only for Store, OK for Sites), which "sounds" it's related the same issue.

Can someone help us please ?
Thanks.

Edit Online is not support outside of Sites, as the Sharepoint protocol relies on the idea of "sites" itself.

Thanks,
Mike

Thanks Mike for your reply !

So, what's about the preview (and thumnails) issue ?

Have you heard (or raise in Jira) anything about this issue ? Mimetypes extraction issue or viewer bug ?

Thanks for your help

Have you got all the support applications installed? i.e. OpenOffice, pdf2swf, ImageMagick? Check the startup log for warnings.

Thanks,
Mike

You're probably right because the issue is reproduced against any document mimetype, not only for MSOffice documents.

I've checked my initial logs to find an error that I've missed but I'm still not enable to find nothing helpful … and finally, I've missed the most important !

Windows service "alfrescoOpenOffice" has not been installed (and I don't know why, if it's my fault or …)
Anyway, I've installed and run it and everything back to normal.

Thanks a lot for your great work (yours and Alfresco team) !
