Some times (very frequent) mule ESB blocks some of SOAP Requests. How can i Stop Mule from doing that? i don't know what is the reason of blocking.
this is how i have configured http-listener in mule config :
<http:listener-config name="HTTP_listener" host="${MachineName}" port="${InboundPort}" doc:name="HTTP listener Configuration" />
<flow name="etryFlow" >
<http:listener allowedMethods="POST" config-ref="HTTP_listener" path="/{name}" doc:name="HTTP"/>
<set-payload value="#[app.registry.pairFactory.createInputStreamWithStringKeyInstance(message.inboundProperties['http.uri.params']['name'],payload))]" />
<jms:outbound-endpoint connector-ref="jms-connector" ref="UnsortedOrders" />
<logger level="INFO" doc:name="Logger" message="****Entry****" />
</flow>
note : the banned requests are converted into BlockingTransferInputStream instead of BufferInputStream.
thank you.
** EDIT **
this is createInputStreamWithStringKeyInstance implementation :
public static Pair<String, byte[]> createByteArrayWithStringKeyInstance(String key, byte value[]) throws IOException {
return new Pair<String, byte[]>(key, value);
}
and Pair.java is a simple Serializable Class (same as JavaFX.Pair) Note : The input is a SOAP XML

Assuming createInputStreamWithStringKeyInstance (which you don't describe, so it's really hard to help you) returns an InputStream, Mule ends up building a JMS StreamMessage (per this call).
From the Mule code, you can see it drains the streaming payload into a StreamMessage with this logic:
while ((len = value.read(buffer)) != -1)
{
streamMessage.writeBytes(buffer, 0, len);
}
which is fine, provided the stream returned by createInputStreamWithStringKeyInstance doesn't do any fancy business behind the scene.
Also note that a JMS StreamMessage is probably not what you want. Did you read its Javadoc? It says:
A StreamMessage object is used to send a stream of primitive types in the Java programming language.
I'm pretty sure you instead want to use a JMS BytesMessage. Mule creates such a message if the payload is a byte[] (per the above linked transformation logic) so you'd rather have a <object-to-byte-array-transformer/> right before the jms:outbound-endpoint.
