IBM Worklight 6.0 - How to bind the datasources?

Question

While deploying a custom war to a WebSphere Liberty profile I get the following exception:

Class org.hsqldb.jdbcDriver not found

I have created and configured the databases by following:

http://pic.dhe.ibm.com/infocenter/wrklight/v6r0m0/index.jsp?topic=%2Fcom.ibm.worklight.help.doc%2Fadmin%2Ft_configuring_liberty_profile_for_derby_manually.html

And edited the server.xml file by following:

http://pic.dhe.ibm.com/infocenter/wrklight/v6r0m0/index.jsp?topic=%2Fcom.ibm.worklight.help.doc%2Fadmin%2Ft_configuring_liberty_profile_manually.html

In the web.xml of the generated custom war the resource references for the datasources have these values:

<res-ref-name>jdbc/WorklightDS</res-ref-name>
<res-ref-name>jdbc/WorklightReportsDS</res-ref-name>

But the datasources defined in the server xml have these others:

<dataSource jndiName="worklight/jdbc/WorklightDS" transactional="false" statementCacheSize="10">
<dataSource jndiName="worklight/jdbc/WorklightReportsDS" transactional="false" statementCacheSize="10">

Anyway I have tried changing the datasource jndi and I get the same exception.

I have also tried to add to the worklight.properties file the properties wl.db.jndi.name and wl.reports.db.jndi.name without success. I supose these properties are not longer valid in WL6.0.

Also tried adding a file ibm-web-bnd.xml to the generated war.

I guess the problem is related to the binding between the application and the Liberty profile datasources.

The only way I have been able to deploy the custom war is setting the Derby databases in the workligh.properties file.

wl.db.url=jdbc:derby:C:/WebSphere/Worklight60DBs/WRKLGHT;create=true
wl.reports.db.url=jdbc:derby:C:/WebSphere/Worklight60DBs/WLREPORT;create=true
wl.db.username=WORKLIGHT

For the error this is my server.xml:

<featureManager>                      
    <feature>jsp-2.2</feature>        
    <feature>ssl-1.0</feature>

</dataSource>

And the only properties I have modified in the worklight.properties file:

publicWorkLightHostname
publicWorkLightProtocol
publicWorkLightPort

How can I deploy a custom war to a Liberty profile using datasources?

Thank you.

Answer 1

is a misleading message. It is related to jndi configuration.

Your jndi references should include CaixaProject in the name like this in the server.xml

<dataSource jndiName="CaixaProject/jdbc/WorklightDS"
<dataSource jndiName="CaixaProject/jdbc/WorklightReportsDS" 

and inside the web.xml is should be like this

<res-ref-name>CaixaProject/jdbc/WorklightDS</res-ref-name>
<res-ref-name>CaixaProject/jdbc/WorklightReportsDS</res-ref-name>
