Issue while deploying custom translator with Teiid 8.0

[manoj.m.agarwal]

Hi,

I am useing JBoss 7.1.1 along with Teiid 8.0  to deploy a custom translator. The implementing class of my executionFactory extands BaseDelegatingExecutionFactory.

I am following the module approch for deploying this translator, so i have created a module for my translator jar and configured it in standalone-teiid.xml as below....

<subsystem xmlns="urn:jboss:domain:teiid:1.0">

...............

<translator name="xyz-translator-safetyHarness" module="com.abc.xyz.teiid.safety"/>

...............

...............

</subsystem>

In my translator jar META-INF/services/org.teiid.translator.BaseDelegatingExecutionFactory  contins "com.abc.xyz.teiid.safety.SafetyHarnessExecutionFactory#xyz-translator-safetyHarness"

When i start Jboss, i get this Error....

17:04:58,956 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 47) Operation ("add") failed - address: ([

    ("subsystem" => "teiid"),

    ("translator" => "xyz-translator-safetyHarness")

]) - failure description: "TEIID50009 Translator \"xyz-translator-safetyHarness\" not found in the module \"com.abc.xyz.teiid.safety\" "

Thanks !

Manoj,

The "ExecutionFactory" class needs to be a top level class and adhere to Java Service semantics. I see you defined as inner class.

Also the file needs to be META-INF/services/org.teiid.translator.ExecutionFactory should contain the implementaion class name, not the BaseExecutionFactory.

Hi Ramesh,

What makes you think that my ExecutionFactory is inner class ? (because its not inner class actulyy...just want to know if i configured it in wrong way and and you said i see it as inner class)

I have copied my ExecutionFactory class below, please let me know if i need to rename the file under META-INF/services and its content.

package com.abc.xyz.teiid.safety;

import java.util.List;

import org.apache.log4j.Logger;

import org.teiid.language.Command;

import org.teiid.metadata.MetadataFactory;

import org.teiid.metadata.RuntimeMetadata;

import org.teiid.translator.BaseDelegatingExecutionFactory;

import org.teiid.translator.Execution;

import org.teiid.translator.ExecutionContext;

import org.teiid.translator.ExecutionFactory;

import org.teiid.translator.Translator;

import org.teiid.translator.TranslatorException;

@Translator(name = "xyz-translator-safetyHarness")

public class SafetyHarnessExecutionFactory

    extends BaseDelegatingExecutionFactory<Object, Object>

{

    private static final Logger              logger               = Logger.getLogger(SafetyHarnessExecutionFactory.class.getName());

    private boolean                          hasConnectionErr     = false;

    private ExecutionFactory<Object, Object> delegate             = null;

    @Override

    public void getMetadata(MetadataFactory metadataFactory, Object conn) throws TranslatorException

    {

        try

        {

            if (!this.hasConnectionErr)

            {

                super.getMetadata(metadataFactory, conn);

            }

        } catch (Exception e)

        {

            logger.warn("Error on getMetaData call", e);

        }

    }

    @Override

    public void setDelegate(ExecutionFactory<Object, Object> delegate)

    {

        this.delegate = delegate;

        super.setDelegate(delegate);

        super.setSupportsFullOuterJoins(delegate.supportsFullOuterJoins());

        super.setSupportsOrderBy(delegate.supportsOrderBy());

        super.setSupportsOuterJoins(delegate.supportsOuterJoins());

        super.setSupportsSelectDistinct(delegate.supportsSelectDistinct());

        super.setSupportsInnerJoins(delegate.supportsInnerJoins());

        super.setMaxInCriteriaSize(delegate.getMaxInCriteriaSize());

        super.setMaxDependentInPredicates(delegate.getMaxDependentInPredicates());

    }

}

Because I saw ClassName#another may be that was a comment, which I misread.

Hi Ramesh,

That is kind of comment where i put the translator name. Its not a inner class. I have checked these links already and configured the custom translator according but still i get the error as mentioned before. Can plese you suggest me something  ?

Thanks !

Manoj

Pls attach your jar file, may be there is more than what you posted here.

Hi Ramesh,

After updating service definition to META-INF/services/org.teiid.translator.ExecutionFactory, i pass thru this issue.

Thanks !
