<wireFormat.jmsText> is broken in some use cases
-------------------------------------------------
Key: TUSCANY-3418
URL: https://issues.apache.org/jira/browse/TUSCANY-3418
Project: Tuscany
Issue Type: Bug
Components: Java SCA JMS Binding Extension
Affects Versions: Java-SCA-1.5
Reporter: Dan Hatfield
>From Simon Laws:
Hi Dan
Yes, I'm seeing it here also. In this case the
WireFormatJMSTextReferenceInterceptor is being added to the wire twice for some
reason and that's causing the problem. Don't know why yet but can you raise a
JIRA [1] for the problem and I'll look at making a fix for it.
------------------------
Basically, I modified the composite files to the have tuscany name space and
placed the <ts:wireFormat.jmsText/> in the appropriate locations.
So the hello world service example now looks like this:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:sca="http://www.osoa.org/xmlns/sca/1.0";
xmlns:ts="http://tuscany.apache.org/xmlns/sca/1.0";
targetNamespace="http://helloworld";
xmlns:hw="http://helloworld";
name="helloworld">
<component name="HelloWorldServiceComponent">
<implementation.java class="helloworld.HelloWorldImpl" />
<service name="HelloWorldService">
<interface.java interface="helloworld.HelloWorldService"/>
<binding.jms
initialContextFactory="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
jndiURL="tcp://localhost:61619">
<destination name="RequestQueue" create="ifnotexist"/>
<response>
<destination name="ResponseQueue" create="ifnotexist"/>
<ts:wireFormat.jmsText/>
</response>
<ts:wireFormat.jmsText/>
</binding.jms>
</service>
</component>
</composite>
And the hello world reference jms example now looks like this:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://helloworld";
xmlns:ts="http://tuscany.apache.org/xmlns/sca/1.0";
xmlns:hw="http://helloworld";
name="helloworldjmsreference">
<!-- A component with a reference promoted as a composite reference -->
<component name="HelloWorldServiceComponent">
<implementation.java class="helloworld.HelloWorldServiceComponent"/>
<reference name="helloWorldService">
<interface.java interface="helloworld.HelloWorldService"/>
<binding.jms
initialContextFactory="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
jndiURL="tcp://localhost:61619">
<destination name="RequestQueue" create="always"/>
<response>
<destination name="ResponseQueue" create="always"/>
<ts:wireFormat.jmsText/>
</response>
<ts:wireFormat.jmsText/>
</binding.jms>
</reference>
</component>
</composite>
I expected this to work based on the fact that the HelloWorld interface is:
public String getGreetings(String s)
And my understanding of wireFormat.jmsText is this:
"The data in the JMS message is the string representation of data coming
from/going to the service operation. The service operation signature is
expected to have a single String parameter"
However, when I run this, I get the following error:
