FirstJCRClient and SimpleExample

[leviter]

Hi,

I ran the FirstJCRClient from the SDK with success and can see the content node created in the Company Home using the Alfresco web client.

Now when I run the SimpleExample it lists all spaces inside the Company Home, but not the content created by the FirstJCRClient.

What is the reason for this and how can I retrieve the content?

Unless re-configured, each sample executes with its own repository data store.

If you modify custom-repository.properties so that dir.root points to the same directory for all samples, you'll see the content created in FirstJCRClient within SimpleExample.

Thanks for your reply, but that is what I've done…

The custom-repository.properties of the FirstJCRClient looks as follows:

dir.root=c:/alfresco/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
‍‍‍‍‍‍‍‍‍‍‍‍

And the custom-repository.properties of the JCRSamples (of which the SimpleExample is part of) looks like this:

dir.root=c:/alfresco/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
‍‍‍‍‍‍‍‍‍‍‍‍

They both point to the same location (which is the location which is used by the 'complete' install of Alfresco). And still I don't see the content created with the FirstJCRClient in the SimpleExample.

Another space I created (Users) in the Company Home using the web client interface is returned in the SimpleExample.

Here is the output I get from it….

As can be seen the 'Users' is returned, but the content item created with the FirstJCRClient isn't… and neither is the content item created with the FirstFoundationClient which I also executed.

I am one step further in solving the problem…

It seems that an exception is thrown!

How can I solve this problem with the SimpleExample?

[davidc]

I've just tried your use case with the latest 2.0 sdk (from SVN).

SimpleExample is displaying the content created in the FirstJCRClient.

I notice from your exception that a namespace prefix is not registered for the uri 'cm'.  Well, 'cm' is not a pre-defined uri, so unless you have defined it yourself, it seems that an item in your repo has an invalid uri.

It still is a bit strange, but I found this topic also about the error I got.

Next thing I did was removing all (self created) nodes and try the examples again…. and now it worked! Guess something was already broken…
