How to make XADisk available as a JCA resource in openejb ?

[Nitin Verma]

As OpenEJB supports JCA standard, and XADisk complies to JCA, the
deployment of XADisk to OpenEJB must be same as any other JCA resource
adapter.

Please see if this link helps : http://openejb.979440.n4.nabble.com/JCA-support-td1288453.html

Hi, I am trying to load XADisk into OpenEJB too...

But there is a lack of documentation on how to load a JCA resource into OpenEJB :-(

Have you succeded ? can you share configuration descriptors ?

Hello Benoit,

I do not have an experience with openejb. Can you share any specific exceptions/problems which you are seeing?

Thanks,

Hello,

here is the result of my first test :

deploy a service-jar in "META-INF/com.mycompany" openejb folder :

<?xml version="1.0" encoding="UTF-8"?>

<ServiceJar>

  <ServiceProvider

      id="XADiskProvider"

      service="Resource"

      types="javax.transaction.xa.XAResource"

      class-name="org.xadisk.connector.outbound.XADiskManagedConnectionFactory">

  </ServiceProvider>

</ServiceJar>

I am using XADiskManagedConnectionFactory because other factory cannot be loaded (constructor must have zero arguments for server to load it)

in openejb.xml, adding this :

<Connector id="FilerLive" provider="com.mycompany#XADiskProvider">

xaDiskHome D:/Temp/FilerXADiskSystem

instanceId 1

enableClusterMode false

clusterMasterPort 999

</Connector>

I added clusterMasterPort because I have the following error when openejb starts :

2014-11-17 17:12:11,381Z|DEBUG|main|Op.options|Using default 'openejb.tempclassloader.skip=none'  Possible values are: none, annotations, enums or NONE or ALL

org.apache.xbean.recipe.ConstructionException: Unable to convert property value from java.lang.String to java.lang.Integer for injection public void org.xadisk.filesystem.FileSystemConfiguration.setClusterMasterPort(java.lang.Integer)

at org.apache.xbean.recipe.ObjectRecipe.setProperty(ObjectRecipe.java:503)

at org.apache.xbean.recipe.ObjectRecipe.setProperties(ObjectRecipe.java:371)

at org.apache.xbean.recipe.ObjectRecipe.internalCreate(ObjectRecipe.java:286)

at org.apache.xbean.recipe.AbstractRecipe.create(AbstractRecipe.java:96)

Do you think it is a bug of XADisk that don't know how to load this propertie ?

An other approach would be to declare something like this :

<Resource id="XADiskResourceAdapter-1" type="org.xadisk.connector.XADiskResourceAdapter">

    xaDiskHome D:/Temp/FilerXADiskSystem

    instanceId 1                                                    

    ...

</Resource>

Is the class org.xadisk.connector.XADiskResourceAdapter th good one ?

Hello Benoit,

I am sorry I still cannot give you a clue on what may be happening; openejb is an unknown area to me.

Thanks,

Here is the solution (works fine for me) to deploy XAdisk as openejb JCA resource adaptor :

1) insert a service-jar.xml file into directory META-INF/com.my.company (I don't know why but it requires the service-jar.xml file to be inside the XAdisk jar (and not rar as our openejb version seems to do not support it), with this content :

<?xml version="1.0" encoding="UTF-8"?>

<ServiceJar>

  <ServiceProvider

      id="XADiskAdapter"

      service="Resource"

      class-name="org.xadisk.connector.XADiskResourceAdapter">

  </ServiceProvider>

  <ServiceProvider

      id="XADiskFactory"

      service="Resource"

      class-name="org.xadisk.connector.outbound.XADiskManagedConnectionFactory">

  </ServiceProvider>

</ServiceJar>

2) in server config (openejb.xml), insert theses 2 sections :

<Connector id="Filer Resource Adapter" provider="com.my.company#XADiskAdapter">

        xaDiskHome path/to/xadisk/system/home

        instanceId 1

</Connector>

<Connector id="Filer" provider="com.my.company#XADiskFactory">

        instanceId 1

</Connector>

3) In your EJB, call the XA resource (called "Filer" in this example) :

    @Resource(name = "Filer")

    protected XADiskConnectionFactory xadiskConnectionFactory;

    ...

    XADiskConnection xadc = xadiskConnectionFactory.getConnection();

    etc..
