I'm facing connection refused exception while trying to connect through TCP even in localhost by using camel-netty4.
<route id="test-producer">
<from uri="quartz://{{t1tos.promis.containerupdate.job.detail}}" />
<to uri="bean:haSessionProcessor?method=getHAStatus" />
<log message="Server Status ::: ${body}"/>
<to uri="netty4:tcp://localhost:9001??textline=true&sync=true"/>
<log message="Server Status ::: ${body}"/>
</route>
<route id="test-consumer">
<from uri="netty4:tcp://localhost:9001clientMode=true&sync=true&textline=true"/>
<log message="Invert Server Status ::: ${body}"/>
</route>
Please advice to resolve the issue, I'm not able to find a working example for this. Do I need to configure host address and port number.

I am developing a sample route
FROM: SOURCE ENDPOINT URI
Doing some transformation(Ex: XML TO JSON)
TO: TRANS ENDPOINT URI // Connection Error Occurred at this TRANS endpoint
TO: TARGET ENDPOINT URI
I need to send my message directly to TRANS ENDPOINT URI not FROM endpoint again. Because I have already done some transformation before in the middle of FROM endpoint to TRANS endpoint. I am saving my message using
OnExpection useorginalmessage=false and saved in my local directory with the filename
So I need to send the transformed message to the TRANS endpoint URI.
<route>
<from uri="file:C:/MINTS/Source/"/>
<to uri="c:/maps/xmltojson.xslt"/>
<to uri="file:C:/MINTS/TRANS/"/><!--connection error or exception occured -->
<to uri="file:C:/MINTS/TARGET/"/>
<onException useOrginalMessage=false>
<exception>java.lang.Exception</exception>
<handled>
<constant>true</constant>
</handled>
<process ref="MyExceptionProcessor" />
</onException>
</route>
I have a mock endpoint at 8001 that will echo anything provided to it.
I have an http endpoint that will submit the end of the URL to the mock endpoint, and provide a response from the endpoint's response.
That works fine.
The challenge is, I want the http route to use only 1 tcp connection to the 8001 endpoint.
I created a worker group as explained elsewhere, and set the worker count to 1. Looking through the source code, I'm thinking this approach should work.
However, when I do this bash command:
for a in {1..5}; do curl "http://localhost:8080/upstream/REQUESTNUM$a" > $a.txt & done;
I see multiple connections to 8001. I would have expected the http endpoint requests would have to share a single pool worker, but that doesn't seem to be the case.
Perhaps I am missing something, or perhaps there is another way to accomplish my goal of using only 1 back-end tcp connection for all the http requests.
How do I accomplish it?

Looking at the logs, with TRACE level logging, I saw the NettyProducer's pool was indeed set to use 1 max active connection, but the NettyProducer was allowed 100 idle connections. I changed the following line and it is now behaving as expected:
<to
uri="netty4:tcp://localhost:8001?workerGroup=#sharedPool&sync=true&textline=true&keepAlive=true&disconnect=false&reuseChannel=true&producerPoolMaxActive=1&producerPoolMaxIdle=1" />
I assumed the "producer" settings were only good for the producer side (netty in mock host route) of the connection, but it looks like they can be used by the consumer end (netty in http route), too.
edit: I confused the terms producer and consumer and got that backwards above. Seeing that the "to" element is producing a request for something to consume, the producer* parameters make sense for (netty in http route). The (netty in mock host route) is the consumer of requests.
<route>
<from uri="file://inbox?move=.txt"/>
<to uri="netty:tcp://localhost:5150?encoders=#encoders&sync=false"/>
</route>
I need to send files to a remote legacy tcp server via a socket (IP and port ). this server is sometimes unavailable so :
1- I need to check if the remote tcp server(socket ) is available.
2- if not , i need wait 5 minutes.
I tried several options but none is working.
thanks
I made it worked with the following config :
<route id="step1" trace="false">
<from uri="file:/dev/tmp/datain/?sortBy=file:name;&delete=true&maxMessagesPerPoll=1" />
<convertBodyTo type="java.lang.String" />
<to uri="direct-vm:toTcp?block=true&timeout=10000" />
</route>
<route id="step2" trace="false">
<from uri="direct-vm:toTcp?block=true&timeout=10000" />
<to uri="netty4:tcp://localhost:7000?sync=true&textline=true&requestTimeout=50000&synchronous=true" />

I am new to apache camel.
I want to create a service bus (middle ware) using apache camel by making a jetty Post request and then get the response from the server.
Here is what I've done
<route streamCache="true">
<from uri="jetty:{{wrapperEntry.protocol}}://{{wrapperEntry.host}}:{{wrapperEntry.port}}/rsb/SubmitNewCaseForAndroid?continuationTimeout=0" />
<convertBodyTo type="java.lang.String" />
<to uri="direct:helloworld"/>
</route>
<route streamCache="true">
<from uri="direct:helloworld"/>
<transform>
<simple>
Hello World
</simple>
</transform>
<convertBodyTo type="java.lang.String" />
</route>
the request goes successfully to the server and submit my case, other wise I cannot get the response back from the server.
Note: the response comes from the is the server is string it comes like this
'code':0,
'description':'operation completed succrssfully',
'complaintId':'45285'
Thank in Advacnce
When using ssh component to launch a remote scp command I must set the body. The ssh component is using the body as the command to be executed remotely.
What I want to achieve is this:
Monitor folder for files. The "from" is using delete=true as I don't want to keep files once route is completed.
Copy the file on the DMZ server using sftp.
Launch a scp on the DMZ server using ssh.
In case of failure, scp does return code greater than 0, rename the file with ".failed".
Unfortunately using ssh require that I overwrite the body and I'm loosing the content of my file. I tried to use inOnly, sending to another route, but it does not make a copy of the file but probably a copy of the file pointer. I can't use wireTap because by the time it complete the remote execution, the route is completed and the file removed. I cannot use (I think) a temporary variable because the file can be up to gigabyte in size.
I'm using Camel version 2.12.1 running under Karaf 2.3.2. I'm trying to use blueprint XML only to avoid java coding as much as possible. Below a sample. The result, in case of non-zero exit code from ssh component, is the file contain my remote command.
<route id="RemoteTest1">
<!-- 1. Monitor for incoming files -->
<from uri="file:///data/karaf/tmp/RemoteTest1/?delete=true"/>
<!-- 2. Copy file on DMZ server -->
<to uri="sftp:username#myDmz.com//home/RemoteTest1/?privateKeyFile=myPrivateKey.pk"/>
<!-- 3. Execute scp remotely -->
<setHeader headerName="remoteCommand">
<simple>scp /home/RemoteTest1/${file:name} someuser#acme.com:${file:name}</simple>
</setHeader>
<doTry>
<inOnly uri="direct-vm:remoteExec"/>
<log message="Success"/>
<doCatch>
<exception>java.lang.Exception</exception>
<!-- 4. In case of failure rename the file by adding .failed -->
<to uri="file:?fileName=${file:absolute.path}.failed"/>
<log message="Failed"/>
</doCatch>
</doTry>
</route>
<route id="remoteExec">
<from uri="direct-vm:remoteExec"/>
<setBody>
<simple>${header.remoteCommand}</simple>
</setBody>
<to uri="ssh://username#myDmz.com?certResource=file:resources/keys/myPrivateKey.pk"/>
<!-- Throw exception on remote error -->
<choice>
<when>
<simple>${header.CamelSshExitValue} != '0'</simple>
<throwException ref="remoteExecException"/>
</when>
<otherwise>
<log message="scp completed normally"/>
</otherwise>
</choice>
</route>
<bean id="remoteExecException" class="java.lang.Exception">
<argument value="Failed remote execution" />
</bean>
Is there a solution? Any help or tip would be appreciated.
Thanks
