Using camel to route from webapp - spring

I am trying to use camel to route a message from my web app to a queue and I am using a bean reference to grab the message from a function that is run whenever an input is given to the browser. However, camel creates a Null exception when it continues to poll because there isn't always an input every half second. How can I make the camel only pick up the message when there is one to pick up? Browserbean is the function that returns the message from the browser.
Here is my camel route:
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="browserBean"/>
<to uri="jms:queue:testQSource"/>
<to uri="myBean"/>
<log message="Routing message from testQSource to testQDestination queue with data ${body}"/>
<to uri="jms:queue:testQDestination"/>
<to uri="finalBean"/>
<log message="message: ${body}"/>
</route>
</camelContext>
<camel:camelContext id="camel-client">
<camel:template id="camelTemplate" />
</camel:camelContext>
<bean id="jms" class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
<bean id="myBean" class="com.example.integration.modifier"/>
<bean id="finalBean" class="com.example.integration.ActionApp"/>
<bean id="browserBean" class="com.hello.integration.GreetingController"/>
</beans>
Here is the stack trace I get every second or so:

It just means the server closed the connection - look at the server logs.

how to use ExecutorChannel in spring integration?

Firstly thanks for attention
i defined ExecutorChannel and task executor in my spring integration project, for async processing on messages with spring batch, as bellow :
<bean id="ftpSessionFactory" class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
<property name="host" value="${ftp.server.ip}"/>
<property name="port" value="${ftp.port}"/>
<property name="username" value="${ftp.username}"/>
<property name="password" value="${ftp.password}"/>
<property name="clientMode" value="2"/>
<property name="fileType" value="2"/>
</bean>
<int-ftp:outbound-gateway id="gatewayGET"
local-directory-expression="'./backup/' +#remoteDirectory"
session-factory="ftpSessionFactory"
request-channel="toGetFilesChannel"
reply-channel="toRemoveChannel"
command="get"
command-options="-P"
expression="payload.remoteDirectory + '/' + payload.filename"/>
<int:channel id="toRemoveChannel">
<int:interceptors>
<int:wire-tap channel="logger2"/>
</int:interceptors>
</int:channel>
<int:transformer input-channel="toRemoveChannel" output-channel="outboundJobRequestChannel">
<bean class="ir.ali.configuration.FileMessageToJobRequest">
<property name="fileParameterName" value="fileName"/>
</bean>
</int:transformer>
<int:channel id="outboundJobRequestChannel">
<int:dispatcher task-executor="simpleExecutor"/>
</int:channel>
<task:executor id="simpleExecutor" pool-size="10-1000"
queue-capacity="5000"/>
it's work correctly , but thrown bellow exception:

That exception is unrelated to the channel type.

It just means your ftp server closed the connection while listing the files.

What to retrieve:
I want to get the meaningful message always, like in this case:
The value '' of element 'ds1:HomecomingDate' is not valid.
Every message contains the following line at the start:
org.xml.sax.SAXParseException;
and in every message, stack trace start from this line:
at org.apache.xerces.
so i want to get the message in between. I tried with the following property mediator but haven't got any luck.
<property xmlns:ns2="http://org.apache.synapse/xsd" xmlns:ns="http://org.apache.synapse/xsd" name="DesiredValue" expression="fn:substring(get-property('ERROR_DETAIL'),1,fn:substring-before(get-property('ERROR_DETAIL'),"org.apache."))" scope="default" type="STRING"></property>
We can do like this
<property name="MSISDN" scope="default" type="STRING" value="94710000000"/>
<property expression="fn:substring($ctx:MSISDN, 3)"
name="MSISDN_WITHOUT_COUNTRY_CODE" scope="default" type="STRING" xmlns:ns="http://org.apache.synapse/xsd"/>
The output would be 710000000
Can you try below properties:
<property xmlns:ns="http://org.apache.synapse/xsd" name="Cause" expression="get-property('ERROR_MESSAGE')"/>
<property xmlns:ns="http://org.apache.synapse/xsd" name="ERROR_CODE" expression="get-property('ERROR_CODE')"/>

#SendTo("/topic/greetings")
public Greeting greeting(HelloMessage message) throws Exception {
//Thread.sleep(3000); // simulated delay
return new Greeting("Hello, " + message.getName() + "!");
}
}
Even though I attempt filter out the null bodies, I am still getting the error. Am I filtering them out too late?
You cannot put the filter inside of from tag. The below route should work :)
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="browserBean"/>
<filter>
<simple>${body} == null</simple>
<stop/>
</filter>
<to uri="jms:queue:testQSource"/>
<to uri="myBean"/>
<log message="Routing message from testQSource to testQDestination queue with data ${body}"/>
<to uri="jms:queue:testQDestination"/>
<to uri="finalBean"/>
<log message="message: ${body}"/>
</route>
You can also use a choice clause, as another way to do it. Here is an example:
<route>
<from uri="direct:routePublishedResponse"/>
<bean ref="caseHearingHandler"/>
<choice>
<when>
<simple>${body} != null</simple>
<to uri="direct:resultSubRoute">
</when>
<otherwise>
<log message="skipping due to NULL body" loggingLevel="DEBUG" />
</otherwise>
</choice>
</route>

I am expecting that Apache CXF will make my kerberos config in jaxws-client be available on my JaxWsProxyFactoryBean. As it turns out, that's not the case. I get the error below:

The http conduit name is not the conduit address, You need to change the http:conduit name just like this
<http:conduit name="*.http-conduit" />
