FirstFoundation explanations

chapeaurouge — Fri, 25 Jul 2008 14:19:17 GMT

Hi all,Starting on extending a bit alfresco to fit our needs, We will create several thousands specific financial documents in batch, getting metadata from one place, and the actual doc from another, for easier archiving and searching.Got a couple basic questions. I am using the Java Foundation API,

The Foundation Services API is an in-process API, in other words it's intended for developing code that will run inside the Alfresco web app. For out-of-process code that has to interact with a remote Alfresco server, you'll need to use one of the remote APIs (listed in order of preference):

Web Scripts - http://wiki.alfresco.com/wiki/Web_Scripts

SOAP Web Services - http://wiki.alfresco.com/wiki/Alfresco_Content_Management_Web_Services

URL Accessible Operations - http://wiki.alfresco.com/wiki/URL_Addressability

JCR-RMI - http://wiki.alfresco.com/wiki/JCR-RMI_Extension (not recommended)

The reason the Web Client needs to be restarted after running the FirstFoundationClient is that you're running two copies of Alfresco (the Web Client and FirstFoundationClient) against a single persistent repository (alf_data directory / database). This is effectively a two-node Alfresco cluster, however neither the vanilla Web Client nor the FirstFoundationClient example are configured as a cluster by default, so content modification events do not get broadcast between the two "nodes" in the cluster (which is why restarting fixes things - that clears out the various in-memory caches). Note that it's entirely possible to configure the Web Client and FirstFoundationClient as a cluster - they're simply not configured that way by default.

Without diving into the code I'm not sure what the first error is caused by, but the second is often a symptom of either not writing the content of a node correctly or not committing the transaction the write operation is within properly.

As for tutorials, the various SDK examples (including FirstFoundationClient) are one of the better places to start - they demonstrate various different techniques, including a SOAP Web Service client (which is one of the ways I'd suggest handling your bulk load requirement via an external application).

Cheers,
Peter

Hi Peter,

Thanks for the explanations.

So I guess I will have the same issues with the JCR API? I have read, however, that JSR-170 (and upcoming) is a good way to be standard compliant, and that multitude of CMS/DMS uses it. I'd love to leverage that. What do you think?

I will take a more in-depth look at the Web Scripts and SOAP services. I am not familiar with these terms too much, so it kind of scared me off at first (that's why I usually prefer the most "desktop" oriented approach )

Thanks for your time. Cheers,

fred

So I guess I will have the same issues with the JCR API?

If you wish to use JCR to access an Alfresco server out-of-process (ie. remotely) you could use the JCR-RMI extension (http://wiki.alfresco.com/wiki/JCR-RMI_Extension). There are several problems with using JCR-RMI however, the most glaring of which (imvho) is that JCR was never really intended to be a remote API (see for example http://research.sun.com/technical-reports/1994/abstract-29.html for a discussion of why this matters).

I have read, however, that JSR-170 (and upcoming) is a good way to be standard compliant, and that multitude of CMS/DMS uses it. I'd love to leverage that. What do you think?

In my experience very few CMSes support JCR (at least in it's JSR-170 incarnation - perhaps JSR-283 will get more traction), which, amongst other things, makes me wonder if it really is a good abstraction of a CMS. Add to that it's unnecessary Java centricity and (imvho) it's value is even more questionable.

I'd encourage you to investigate Web Scripts (REST) as a basis for communicating with Alfresco (or any other system for that matter) - it really is very approachable and the fact that it's so "light" (from a dependency perspective) makes it pretty compelling.

Cheers,
Peter

What is the possible reason behind this error? I have a database called alfresco with grant options as described in the sdk wiki.

custom-repository.properties file looks like this:

#
# Sample custom content and index data location
#

dir.root=./alf_data

db.username=alfresco
db.password=alfresco

#
# MySQL connection (This is default and requires mysql-connector-java-3.1.12-bin.jar, which ships with the Alfresco server)
#
db.driver=org.gjt.mm.mysql.Driver
db.url=jdbc:mysql://localhost/alfresco

#
# Oracle connection (requires ojdbc14_g.jar or equivalent jar in shared libraries location)
#
#db.driver=oracle.jdbc.OracleDriver
#db.url=jdbcracle:thin:@localhost:1521:alfresco

#
# Sybase connection (requires jconn2d.jar or equivalent jar in shared libraries location)
#
#db.driver=com.sybase.jdbc2.jdbc.SybDriver
#db.url=jdbc:sybase:Tds:localhost:2638/alfresco

since i have uncommented the mysql section and the username and password one as well. My db username is root and has no password.

I had also issued the command as described in wiki:

mysqladmin -u root -p create alfresco
mysql -u root -p -e "grant all on alfresco.* to 'alfresco'@'localhost' identified by 'alfresco' with grant option;"
mysql -u root -p -e "grant all on alfresco.* to 'alfresco'@'localhost.localdomain' identified by 'alfresco' with grant option;"‍‍‍

I do not have Alfresco running since i believe it is not required for this example.

I have followed the http://wiki.alfresco.com/wiki/Alfresco_SDK#Downloading_and_Installing_the_SDK

However, the line "Check the database connection details are correct and then it's simply a case of running or debugging the FirstFoundationClient.java application within Eclipse." is not clear, which file do i have to change the database connection details in if not custom-repository.properties where i have already uncommented the username and password line?

Please help,
Best Regards,
Vibhu.

Hi Vibhu,

i have the same error during the last few builds. My last test was today with the 1-october-builds :cry:

Is this a bug, so anybody has this problem or is this an individual error, perhaps false configuration???

I use eclipse ganymedem and the 1-october-builds. The only changes in the Alfresco-Configuration is the MySQL-Repository.

Hello, please make sure that your hosts file is correctly set.

i modified my to look like this.

Hi Vibhu,

what's your "hosts file"? In the FFC-files i can't find this.

Re: FirstFoundation explanations

vibhutewary — Thu, 09 Oct 2008 18:25:14 GMT

Hi, in Linux fedora, the hosts file resides as "/etc/hosts"
What's FFC?

Vibhu.

Re: FirstFoundation explanations

major_king — Thu, 16 Oct 2008 08:05:18 GMT

FFC = FirstFoundationClient

I have alfresco running on xp. So i have no etc/hosts. I will check windows configuration.

major_king — Thu, 23 Oct 2008 12:59:22 GMT

Hello together,

now i got the First Foundation Client example (SDK Labs 3c) working

On SDK AlfrescoEmbedded, add the following libraries (look at dependencies folder) to Referenced Libraries:
json
ibatis
xmlrpc
alfresco-jlan-embedded (look at WEB-INF/lib folder in the alfresco.war)

At least, configure custom-repository.properties in FirstFoundationClient-project.

christian
