Server version: Apache Tomcat/7.0.27
OS Name: Linux
OS Version: 2.6.32-431.el6.x86_64
Architecture: amd64
JVM Version: 1.7.0_40-b43
JVM Vendor: Oracle Corporation
Note: SELinux IS enabled.

When attempting to preview a document, I get the following error:
Conversion: IO exception executing command:
(and there is no command listed.

In the catalina.log file there is this, that seems related:

Code: Select all

Caused by: java.io.IOException: Cannot run program "": error=2, No such file or directory
        at java.lang.ProcessBuilder.start(ProcessBuilder.java:1041)

        at com.openkm.util.DocConverter.pdf2swf(DocConverter.java:472)
        ... 42 more

This may also be helpful:

Code: Select all

ls -l /opt/openkm-6.2.5-community/tomcat/bin/pdf2swf
-rwxrwxr-x. 1 root root 4027300 Apr  3  2013 /opt/openkm-6.2.5-community/tomcat/bin/pdf2swf

And because it's selinux:

Code: Select all

ls -ladZ /opt/openkm-6.2.5-community/tomcat/bin/pdf2swf
-rwxrwxr-x. root root unconfined_u:object_r:usr_t:s0   /opt/openkm-6.2.5-community/tomcat/bin/pdf2swf

Is SELinux the problem?

Thanks.

I'm getting a little closer. I had overlooked the configuration options in the Administration panel. So I added the path to pdf2swf, and the path to soffice.bin and restarted catalina. The original error is gone, but now I get one that simply says "Conversion:" The catalina.out log says:

Code: Select all

I guess that's progress, so I'll keep working on it. Maybe someone will be able to assist.

Ah, I found it in the documentation. To enable PDF previews. I needed to start with
Enable Document Preview, and read it more carefully.

The last error was because,

Since OpenKM 5.1.9 the pdf2swf command line parameters should be added in the configuration property, for example:
system.swftools.pdf2swf=/usr/bin/pdf2swf -T 9 -f ${fileIn} -o ${fileOut}

so now I'm moving forward. It now works with PDF documents (only). It still does not work with OpenOffice or MS Word doc files.

I have the path defined for soffice.bin. I have tried both LibreOffice and OpenOffice, and I get the same errors. As directed in OpenOffice configuration issues, I attempted to download an OpenOffice text file as a PDF. It produced the same error as seen when trying to preview the document.

Fixed. I finally found the configuration checker utility and it showed me that the path I had entered for "soffice.bin" was not correct. The wiki documentation is INCORRECT on this. It says to enter the path to the location for "soffice.bin" but it really needed the path to the OpenOffice or LibreOffice application. It appends "program/soffice.bin" to whatever you put in this configuration option.

Can you provide us the wiki url and we'll try to explain it better.

I thought I followed instructions to enter the full path to soffice.bin in the system.openoffice.path parameter. However, now I cannot find any wiki page that says to do that. Perhaps I simply misread "OpenOffice configuration issues"where it says

Inside the path define at system.openoffice.path you should see a directory called program, where can see soffice.bin file. This file is used by OpenKM to start the OpenOffice / LibreOffice service. I included the full path (including the "program" directory) and of course that did not work. It should be the path to the OpenOffice (or LibreOffice) program.

Thanks.
