decoupling OpenOffice and Alfresco

dmakovey

I've got a dilemma: installing Alfresco as WAR on the server we used J2EE stack provided by JPackage team using SUN's JVM etc (it's a requirement). However since we're running RedHat and they ship now their own re-packaged JPackage stack using gcj to compile "natively" we avoid any RedHat Java-related packages. Now, to install OpenOffice on RedHat you need to install some libraries that create conflict between JPackage installed libraries and RedHat's repackaged ones. To eliminate this problem it seems the most natural solution would be to decouple Alfresco and OpenOffice and deploy them on 2 separate machines.

Now Alfresco expects OpenOffice to be on 127.0.0.1:8100 but OO sits on 192.168.1.22:8100 . How do I configure Alfresco to access OpenOffice remotely on 192.168.1.22:8100? (for now I'm doing ssh port forwarding, however it's a workaround - I'd rather configure Alfresco to do "the right thing")

Is decoupling approach even feasible? Is there a strict requirement for OO to be on the same machine as Alfresco? Having it decoupled I can (I think) recycle same OO instance for several instances of Alfresco.

Yes, this is possible.

On the remote machine, in the script for starting OpenOffice use something like: (my path is for Mac OS X, replace it for Linux)

'/Applications/OpenOffice.org 2.3.app/Contents/MacOS/soffice' "-accept=socket,host=156.124.12.101,port=8100;urp;StarOffice.ServiceManager" -nologo -headless &

Note the host and port arguments.

In Alfresco, under the extensions directory (ex. tomcat/shared/classes/alfresco/extension)

create a custom-content-services-context.xml file

insert into the file:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

        <bean id="openOfficeConnection" class="net.sf.jooreports.openoffice.connection.SocketOpenOfficeConnection">
                <constructor-arg type="java.lang.String" value="156.124.12.101"/>
                <constructor-arg type="int" value="8100"/>
        </bean>

</beans>

Again note the address (which can be IP or DNS) and the port

awesome. It worked as expected. Thanks for quick reply!

dmakovey

is it me or is Enterprise 2.1.2 doesn't send documents over TCP anymore? I can swear 2.1.1 did send stuff over TCP (I ran a quick test originally and I *never* had OO running on the same machine before) and it worked at least once.

Are you getting an error? Can you post it?

got more tcpdump so in case if that's needed I can post it externally as a raw file for further inspection.

Are you using a trial version on enterprise trial. I am wondering about the read only information there…..

dmakovey

As far as I can tell - it's a full enterprise edition.

14:38:53,813 INFO  [service.descriptor.DescriptorService] Alfresco license: Enterprise Network granted to Enterprise Network License Holder (does not expire)
14:38:53,813 INFO  [service.descriptor.DescriptorService] Alfresco started (Enterprise Network): Current version 2.1.2 (268) schema 81 - Installed version 2.1.2 (268) schema 81

moreso - I checked and files are created just fine under /var/tmp/tomcat6 (both source .doc and destination .pdf). It's just that .pdf is 0-length.

I'm not a "pro" with OO communication etc, but could it be that ReadOnly is passed to OO just to discourage it from trying to modify original document?

dmakovey

Can anybody reproduce similar problem with 2.1.2E ? Should I start considering switching to 2.2.0E maybe ?

I've updated the wiki page with instructions to enable the remote OO transformations.

Basically, I created an AMP that will add the code to perform the transformations. You will also need to add the remote-openoffice-context.xml file configured to reference the remote OpenOffice.
