http-outbound-gateway InvalidMimeTypeException due to a ' ' character - spring-integration

I am using http-outbound-gateway to download files from an external service. It works fine except for the times when there is a space in the mime type. I get the following exception:
[13552] 22-Mar-2016 16:09:59-103 ERROR [task-scheduler-4] com.hsbc.clearing.ClearingHouseIntegration - org.springframework.messaging.MessageHandlingException: HTTP request execution failed for URI [https://www.somedomain.com]; nested exception is org.springframework.http.InvalidMediaTypeException: Invalid mime type "application/x-zip; name=Some file.xml.zip": Invalid token character ' ' in token "Some file.xml.zip"

I have no control over what comes in a response content type. Is there any workaround to make it work?

From big height your server isn't right according the RFC 202616 and RFC 1341 and has to fix that value to the
application/x-zip; name="Some file.xml.zip"
To workaround it you have to extend RestTemplate and override its:
protected <T> ResponseExtractor<ResponseEntity<T>> responseEntityExtractor(Type responseType) {
return new ResponseEntityResponseExtractor<T>(responseType);
}
To return a modified version of HttpMessageConverterExtractor, where you populate:
MediaType contentType = getContentType(responseWrapper);
on your own, bypassing the response.getHeaders().getContentType().
Not a Spring Integration issue, BTW, neither Spring MVC though...

$SPARK_HOME/bin/spark-submit \

With Spark 3.1.1 you must use Delta 1.0.x - currently 1.0.0. 0.8.0 is compatible only with Spark 3.0.x (see compatibility matrix):
But most probably that you have an external shuffle service that is running on incompatible version of the Spark, like, your code is on 3.1.1, and shuffle service is on 3.0.x

How to handle FtpOutboundAdapter connection exception in spring integration flow

My flow ends with something like:
.handle(ftpAdapters.rtwFtpOutboundHandler(), out -> out.advice(after()))
.get();
In the advice, we have codes to handle:
#Bean
public ExpressionEvaluatingRequestHandlerAdvice after() {
logger.debug("Evaluating expression advice. ");
ExpressionEvaluatingRequestHandlerAdvice advice = new ExpressionEvaluatingRequestHandlerAdvice();
advice.setSuccessChannel(rtwSourceDeletionChannel());
advice.setFailureChannel(rtwFtpFailureHandleChannel());
advice.setPropagateEvaluationFailures(true);
return advice;
}
But above code is not enough to handle, exception raised with ftp connection bean. (Default Session Factory in the case I am using.
how to handle these exception in flow?

According your stack trace the ExpressionEvaluatingRequestHandlerAdvice catches an exception for the Connection timed out: connect and just re-throws it as is. Because you don't have configured onFailureExpression:
catch (Exception e) {
Exception actualException = this.unwrapExceptionIfNecessary(e);
if (this.onFailureExpression != null) {
Object evalResult = this.evaluateFailureExpression(message, actualException);
if (this.returnFailureExpressionResult) {
return evalResult;
}
}
if (!this.trapException) {
throw actualException;
}
return null;
}
The behavior is that
advice.setSuccessChannel(rtwSourceDeletionChannel());
advice.setFailureChannel(rtwFtpFailureHandleChannel());
does not make sense when appropriate expressions are not configured.
So, if you would like to handle FTP exceptions with that advice, you need to configure an onFailureExpression there. Something like setOnFailureExpressionString("#exception") should be enough. This way a caught FTP exception is going to be sent as a payload into that configured rtwFtpFailureHandleChannel.
I think this is time to improve an ExpressionEvaluatingRequestHandlerAdvice to require expression when channels are configured. Otherwise they does not make sense.
The fix is here: https://github.com/spring-projects/spring-integration/pull/2738

Getting ReplyRequiredException in Spring cloud dataflow

I am trying out spring cloud dataflow. I created a stream with 'source' as "maven://org.springframework.cloud.stream.app:file-source-kafka:1.0.2.RELEASE", I have written my custom processor and the 'sink' is "maven://org.springframework.cloud.stream.app:log-sink-kafka:1.0.2.RELEASE". The source read a file from a particular directory and pass the reference of the file to the processor. But I see following exception in the processor. The properties for processor looks like below

Spring-Integration bridging from publish-subcriber channel to direct-channel

I have a strange behavior. As I know you use int:bridge to connect from one channel to the next. So I try to connect a publish-subscriber-channel to a direct channel. The bridge is used in another module in a multi-module-project.
The channels itself are defined as follows in module A:
<int:publish-subscribe-channel
id="ticketOutgoingChannel"
datatype="*.model.Ticket"
/>
<int:channel id="ticketIncomeChannel" datatype="*.model.Ticket" />
The Bridge is defined in Module B:
<int:bridge id="ticketOutgoingIncomeBridge"
input-channel="ticketOutgoingChannel"
output-channel="ticketIncomeChannel"
send-timeout="1000"
/>
When I comment out that bridge, my application works without any issues. I have access to the ticketOutgoingChannel from the other modules, tested as:
<int-stream:stdout-channel-adapter
channel="ticketOutgoingChannel"
/>
When activate the bridge I become:
org.springframework.messaging.MessagingException: failed to resolve channel name 'DECRPYTED'; nested exception is
org.springframework.messaging.core.DestinationResolutionException: failed to look up MessageChannel with name 'DECRPYTED' in the BeanFactory.; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'DECRPYTED' is defined

Suddenly it wants to have a bean names DECRYPTED, but I have no idea why??? There is no bean named like that.
I am using Spring-Boot latest 1.3.x version.
Sorry for that spam, the issue was somewhere else. I have a router what use the header-name ticketSecured, BUT I didn`t have mapped that to a channel. So it tried to resolve the channel bean by name. Thats why it looked for DECRYPTED bean. Maybe someone helps that spam.
<int:header-value-router
id="messageRouter"
input-channel="ticketIncomingChannel"
header-name="ticketSecured"
>
<int:mapping value="NEW" channel="newTicketIncomingChannel" />
<int:mapping value="ENCRYPTED" channel="encryptedTicketIncomingChannel" />
<int:mapping value="DECRYPTED" channel="decryptedTicketIncomingChannel" />
</int:header-value-router>

Spring Integration Sync/Async Message Flow

I am new to spring integration and am trying to model a flow in which I have a synchronous request and response via HTTP, but also part of the same flow that delivers
the response to queue, post-processes it, and has a separate process consume that response. So it is synchronous from the perspective of the client invoking the flow;
Asynchronous from within the flow at the point where the response is placed on a queue. I am hosting the gateway-context.xml and amqp-context.xml within an embedded Jetty server
and posting from a separate process via HttpAmqpClientDemo below.
I am able to submit the request and receive the response, but when
I specify the output-channel attribute to deliver to RabbitMQ, I no longer receive a response via the configured int-amqp:inbound-gateway
and instead receive an exception stating the there is 'No reply produced by handler ... AmqpOutboundEndpoint#0'.
The following message handler chain is configured to deliver the return value (com.uscs.cdm.Response) of the ServiceActivator annotated method
to the output-channel "toRabbit".
Even when using the inbound/outbound-channel-adapter pair I receive a HTTP 500 status code when expecting the response from HttpAmqpClientDemo below.
It is my understanding that I should be using the inbound/outbound-gateway pair instead when expected a response from the same message flow.
What am I doing wrong here? Also, should I be using a inbound-channel-adapter ("fromRabbitReply" in gateway-context.xml below) to consume the AMQP post-processed payload?
From the logs below, I do see that 'com.uscs.cdm.Response' is a payload within the flow, but I am having trouble doing anything with it.
Your help would be greatly appreciated.

13:43:23.775 [qtp692680779-32 - /http/receiveGateway2] DEBUG o.s.b.c.w.OrderedRequestContextFilter - Cleared thread-bound request context: Request(POST /http/receiveGateway2)#21c7fd13
The <int-amqp:outbound-gateway> waits for the response, but your <int-amqp:inbound-gateway request-channel="fromRabbit"> doesn't do that and just prints to the console using <int-stream:stdout-channel-adapter>, so it is the end of the message flow: nothing to reply just because no one component do that.
To make a reply for the <int-amqp:outbound-gateway>/<int-amqp:inbound-gateway> pair you don't need to worry about any replyQueue because those gateways take care about that already using Temporary Queue.
From other side all Spring Integration request/reply components sends it result to the replyChannel from request Message header, if you don't specify output(reply)-channel on the component.
So, instead of one-way <int-stream:stdout-channel-adapter> you should have some <service-activator>, or any other two-way component, but without that output-channel option. Everything will work because there is a TemporaryReplyChannel involved.
Please, read more in the Spring Integration Reference Manual.
