Java ConversionException when doing MSWord/Plaintext preview

hello,

I have installed OpenKM-6.3.1 build 8235 on Windows Server 2012 R2. I also installed LibreOffice 5, what is working well anyway. I would "integrate" to this office tool just for able to use "preview" feature inside OpenKM.

For this I set the path of LibreOffice in OpenKM's general settings page
Code: Select all
INSERT INTO OKM_CONFIG (CFG_KEY, CFG_TYPE, CFG_VALUE) VALUES ('system.openoffice.path', 'string', 'C:\\Program Files (x86)\\LibreOffice 5\\program\\');
At OpenKM startp, when tomcat server is starting, I can see this in the catalina.log
Code: Select all

I have made search in this forum and on the "whole internet", but I did not really find such solution what may help for me. As I saw same/similar problem has occurred in the past for other with both OpenOffice/LibreOffice in both Windows/Linux OS, but the suggestions described for those did not helped me at all, and that is why I try turn to you to get some help. I think I missed something wrong, or I have some wring setup somewhere.

The detailed information about the crash, ect can be seen in the attached files.

thanks for your help,

The error is clear, you have not configured the path of libreoffice or openoffice correctly. I have not checked version libreoffice 5 and I do not know if it's some issue related with that version, I suggest you install openoffice ( the error indicate is not finding soffice.bin into the path C:\Program Files (x86)\LibreOffice 5\program, could be some change between version 4 to version 5, I ignore it at this moment, my suggestion is go with openoffice ususally on windows goes betther rather libreoffice ).

hello,

Thanks for your reply.

I have installed OpenOffice 4 on the windows server, as you have suggested, but I did not helped at all. The same error can be seen in the catalina.log when tomcat starts up, and same error window appears in the OpenKM page when I clicked on the preview button.

The error report in the log file is pretty easy to understand, but what else should I set in the OpenKM settings, except the path of OpenOffice? The OpenKM documentation -what I have chcecked- does not says anything else.

PLease see the error in the log file at startup:
Code: Select all
2015-11-28 21:04:22,168 [localhost-startStop-1] INFO  com.openkm.util.DocConverter- system.openoffice.port=2002

java.lang.IllegalStateException: invalid officeHome: it doesn't contain soffice.bin: C:\Program Files (x86)\OpenOffice 4\program

	at com.openkm.servlet.RepositoryStartupServlet.init(RepositoryStartupServlet.java:127)
	at javax.servlet.GenericServlet.init(GenericServlet.java:158)
And please also take a look at the attached pictures about OpenOffice files in the file system, and what is set in OpenKM settings for this.

Do I missed something? If so, what can that be?

thanks for your help,

Your path is not correct, should not include the /program folder !
Also consider, if you added sigar folder to your configuration path, take a look here http://wiki.openkm.com/index.php/Config ... ce_windows

hello,

I have an additional information regarding LibreOffice usage within OpenKM. As I have mentioned in the original post, I would use this instead of OpenOffice, but for same reason LibreOffice won't work.

Now I found the solution. This link https://code.google.com/p/jodconverter/ ... ail?id=103 describes the same/similar problem what I have. Here the solution was to make the basis-link file under "c:\Program Files (x86)\LibreOffice 5\program\" path, than restart tomcat process. I did this, and it works.

So I could use LibreOffice togather OpenKM for preview.

Hopefully this can help for others, who has similar problem.

br,

hello,

Yes, your last reply was helped me lot. I removed "program" in the path of OpenOffice, and set the enviromnent variable for sigar, and finally the preview works as is should.

thanks for your help,
