JpaCluster on Glassfish using persistence.xml: Can not connect to 192.168.56.101 (1 reply)

Doing some prototyping with openJPA + JpaCluster + Sailfin 2 (based on glassfish 2.1) +
JPA.

Using the following persistence.xml:
<persistence-unit name="BM" transaction-type="JTA">
<provider>
org.apache.openjpa.persistence.PersistenceProviderImpl
</provider>
<jta-data-source>jdbc/bm</jta-data-source>
<class>persist.BigCompany</class>
<class>persist.SmallEmployee</class>
<properties>
<property name="openjpa.BrokerFactory" value="ndb"/>
<property name="openjpa.ndb.connectString" value="192.168.56.101:1186"/>
<property name="openjpa.jdbc.SynchronizeMappings"
value="buildSchema(SchemaAction='add')"/>
<property name="openjpa.ConnectionRetainMode" value="transaction"/>
<property name="openjpa.ndb.database" value="bm"/>
<property name="openjpa.ndb.connectVerbose" value="1"/>
<property name="openjpa.DataCache" value="false"/>
<property name="openjpa.ConnectionUserName" value="root"/>
<property name="openjpa.ConnectionPassword" value="system"/>
</properties>
</persistence-unit>

Cluster-j seems to fail to connect to a data node:

in the ndb_mgm show I can see available mysqld(API) nodes:
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=3 @127.0.0.1 (mysql-5.1.47 ndb-7.1.8, Nodegroup: 0, Master)
id=4 @127.0.0.1 (mysql-5.1.47 ndb-7.1.8, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @127.0.0.1 (mysql-5.1.47 ndb-7.1.8)

[mysqld(API)] 4 node(s)
id=50 @127.0.0.1 (mysql-5.1.47 ndb-7.1.8)
id=51 (not connected, accepting connect from any host)
id=52 (not connected, accepting connect from any host)
id=53 (not connected, accepting connect from any host)

I am using the default config.ini:

[ndb_mgmd]
hostname=localhost
datadir=/home/baboune/ndb/one-cluster/ndb_data
id=1

[ndbd default]
noofreplicas=2
datadir=/home/baboune/ndb/one-cluster/ndb_data

[ndbd]
hostname=localhost
id=3

[ndbd]
hostname=localhost
id=4

[mysqld]
id=50

[mysqld]
id=51

[mysqld]
id=52

[mysqld]
id=53

And my.cnf:

[mysqld]
ndbcluster
datadir=/home/baboune/ndb/one-cluster/mysqld_data
basedir=/home/baboune/mysqlc

Note: if I remove the ndb parts in the persistence.xml then everything works as my data
source points to a valid MySQL connection pool.

How to repeat:
Using above persistence.xml configuration deploy an application on a glassfish server.

Some comments on my setup:
- Main machine using windows 7 64 bits running Glassfish
- Virtual machine running Ubuntu Maverick 32 bits + Mysql cluster

Tried the exact same thing but with everything collocated on windows and I seem to get a
link towards the DB:

It is still not good but at least it appears to connect to the NDB API.

So there is some sort of bug going to an external NDB API (not localhost)?
