Publishing JMS message on Solace Topic

I am facing issue while publishing JMS message on Solace server topic.
Actually we are successfully able to send message using jmsTemplate.send() method.
But unable to see the message count on solace client GUI.
Below is my solace configuration.

Based on your comments, it would appear that you are publishing to a topic, but there are no endpoints configured to spool the message.
You can refer to at Adding Topic Subscriptions to Queues for details on how to configure an queue to spool messages that are published to a topic.
To confirm, you can verify whether messages are listed under the "No Subscription Match Logs". In SolAdmin, you can view them by heading to "Logging & Diagnostics" and selecting the "No Subscription Match Logs". The corresponding CLI command for this is show log no-subscription-match
Also, the statistics of your application connection would also display the number of messages received and sent, with any discard reasons. This can be viewed by heading to the "Clients" tab, and selecting the "Client" view. Then, double click on your client and head to "Statistics". Alternatively, the CLI command for this is show client <your-client-name> message-vpn <your-vpn-name> stats

bluemix server gives SQLGrammarException in MySQL

![out put from cf logs app-name --recent
]1I have developed a spring/hibernate-MySQL in backend based application. I have tested the application in the local machine successfully. But when I uploaded the app into IBM bluemix, there is exceptions everywhere when I am accessing service-->Dao methods. It says org.hibernate.exception.SQLGrammarException stating the message like " SELECT command denied to user 'username#75.126.83.16'. Interstingly, when I put a normal JSP without Hibernate/spring Dao but by using the same connection string, that works.
Here is the spring-config.xml

Spring WS - JMS backed endpoint - When endpoint not found

I have a Spring WS Endpoint which gets the payload from a JMS Queue. I use annotation based routing on my endpoint [based on payload root].
If for whatever reason, the routing doesn't happen [due to a typo etc], I only see a warning that there is "No Endpoint Found for Request SAAJSoapMessage". The main issue here is the message is lost! In my case, I would like an exception to be raised and fore the message to go to a Dead Letter Queue. The reliability is super critical here. What's the best way to achieve this. Here is my config:
<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616?jms.redeliveryPolicy.maximumRedeliveries=5" />

Spring json not using the desired root name

I have the following configuration :
<property name="defaultViews">
<list>
<!-- JSON View -->
<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
<!-- XML View -->
<bean class="org.springframework.web.servlet.view.xml.MarshallingView">
<constructor-arg>
<bean class="org.springframework.oxm.xstream.XStreamMarshaller">
<property name="autodetectAnnotations" value="true" />
</bean>
</constructor-arg>
</bean>
</list>
</property>
It creates a json, but the root name is not what i want
#XStreamAlias("house")
#JsonAutoDetect
#JsonRootName(value = "house")
public class TableHouse {
private Long value;
.....
}
For the xml it works fine, however for the json it does not pick up the #JsonRootName.. and outputs json with class name as root...
Any ideas?
You have to enable root-level wrapping. See How do I rename the root key of a JSON with Java Jackson? to have an idea on how to use JsonRootName properly.

Spring configuration - mvc:annotation-driven, AnnotationMethodHandlerAdapter, and JSON

Thanks in advance any help.
I'm trying to get one of my controller methods to return JSON. Starting off with a simple test:
#RequestMapping(value="/myReqPath", method=RequestMethod.GET)
#ResponseBody
public Map<String, String> myJsonMethod() {
Map<String, String> response = new TreeMap<String, String>();
response.put("test", "test");
return response;
}
It's my understanding that I need <mvc:annotation-driven/> added to my servlet context to accomplish this. The problem is when I add it, it breaks my custom AnnotationMethodHandlerAdapter.
[B]How do I extract and add the needed parts of <mvc:annotation-driven/> to return JSON from the controller?[/B]
Here are the pertinent parts of my servlet config:
<!--Skipping this for now...
<mvc:annotation-driven/>
-->
<!-- JSON Marshaling -->

<bean id="sessionArgResolver" class="com.SessionParamArgumentResolver"/>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="customArgumentResolver" ref="sessionArgResolver"/>
</bean>
As it stands, my controller method is invoked however, the browser returns http status 406:
406 Not Acceptable - [url]http://localhost:8080/myApp/myReqPath[/url]
If you already have a custom AnnotationMethodHandlerAdapter declaration, you can just add a list of HttpMessageConverters to it:
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="customArgumentResolver" ref="sessionArgResolver"/>
<property name = "messageConverters">
<list>
<bean
class = "org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name = "objectMapper" ref = "jsonObjectMapper" />
</bean>
</list>
