I am trying to fetch data from db, do mapping and upload to cloud for each record from db one by one. I have done below approach:
select data from db, map each record from the db, then upload.
Mule flow:

Question:
1)Do I need to use object-to-string-transformer to get the data from db and map in java component?
2) How do I upload/send the data each row from db. When i use for each i am getting above error since I have converted db data to string transformer. I am using java component to transform instead of Data Mapper.
EDIT:
After removing object to string transformer, getting following error at the end, i.e after java mapping:

EDIT:2
Solved, after below changes:I have converted to json object after select query as:
<db:select config-ref="PostgreSQL" doc:name="PSI-Select">
<db:parameterized-query><![CDATA[SELECT * FROM clients_int WHERE int_status = 'Reading']]></db:parameterized-query>
</db:select>
<foreach doc:name="For Each">
<json:object-to-json-transformer returnClass="java.lang.Object" doc:name="Object to JSON"/>
<logger message="===Main Flow #[payload]===" level="INFO" doc:name="Logger"/>
</foreach>
Remove the object-to-string-transformer: it transforms the rows enumeration into a String, which prevents for-each to work.
EDIT: Moreover, because the inbound HTTP endpoint is request-response, it will need to return a response to the client. Mule will use the current payload (a Jdbc4Array instance) as the payload of the HTTP response and will fail.
You need to add a set-payload to set the body of the HTTP response to whatever you want to return to the caller. Use an http:response-builder to set response headers, cache directives... as well.
Alternatively, you can switch the HTTP inbound endpoint to one-way. This will return OK to the client immediately, and whether what happens down the flow succeeds or fails.

I'm developing an integration using Mule ESB which needs to read a binary file (.zip) from the file system and create it as an attachment in Salesforce. However, I'm not able to get this work and I'm getting the following error:

I checked the Anypoint exchange and googled, but all the pointers that I'm getting is geared towards text files (like CSVs). Appreciate if someone can share a working example to read a binary file and create it as an attachment in Salesforce (can attach to any object like case object).
I'm using Anypoint Studio 5.4.1 with Mule runtime 3.7.3 EE.
Edit: I was able to resolve the issue. Basically, as #david said, the create method takes a collection and I was not passing it as a collection. Here is the updated code (just the dataweave part):
[
{
ParentId: "b2U7AB010540yZ",
Name: "Test Name",
Description: "Test Descr",
Body: payload
}
]
Note the open and close square brackets. Thanks #david.
What I understand from the SFDC Connector doc, is that the create method expects a collection of objects.
But you're passing a map to it, thus this exception:
Could not find a transformer to transform "SimpleDataType{type=java.util.LinkedHashMap, mimeType='*/*', encoding='null'}" to "CollectionDataType{type=java.util.List, itemType=java.lang.Object, mimeType='*/*'}"
Try adding the map you create in dw:transform-message to a list, using a transformer for this, and it should work.
I'm new in MULE ESB, I have this code and i'm trying sending a http request using http:request with the following format:

</http:request-builder>
</http:request>
But I'm having this error:
Message : Error sendinbut g HTTP request. Message payload is of type: LinkedHashMap
Code : MULE_ERROR--2
Exception stack is:

org.mule.module.http.internal.request.DefaultHttpRequester:190
(http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/MessagingException.html)
The question is how can I do to make a http request with that format using the map?
According to documents
https://www.mulesoft.org/documentation/display/current/HTTP+Request+Connector#HTTPRequestConnector-HTTPRequestBody
The Mule Message payload is converted into a byte array and sent as
the HTTP Request's body. This behavior is carried out always, except
in the following scenarios:
The Mule Message's Payload is a Map of keys and values
Generate the Request Body with
Content-Type:application/x-form-urlencoded
Whenever the message payload is a Map, the connector automatically
generates an HTTP request with the header
Content-Type:application/x-www-form-urlencoded. The keys and values of
the map in the payload are converted into form parameter keys and
values in the body of the HTTP request.
I suppose the map is converter automatically for the request. Correct me if I'm wrong
It was necessary to make a transformation before the
<json: json-to-object-transformer returnClass = "java.util.Map" doc: name = "JSON to Object" />
It is corrected by putting
<byte-array-to-string-transformer doc: name = "Byte Array to String" />
The error you're getting actually is not because your request has something wrong (or at least is not failing at that stage) but that your app is not being able to connect to the http server you're trying to send the request to. You can infer this by the exception you're getting java.util.concurrent.TimeoutException.
In order to troubleshoot please verify the host name and port are typed correctly.

Can you please help me to cast this object correctly so i can access the Payload here ?
Thanks.
There's a bug in your component.
This Arrays.asList(message.getPayload()) wraps the message payload into a list. But the message payload is already a List<RemoteIssues> so this wrapping is unnecessary.
If you look at the source code of the JIRA connector, you'll see that MuleSoft prefers late casting of the RemoteIssue. I suggest you do the same:
for (Object o : ((List) message.getPayload())) {
RemoteIssue ri = (RemoteIssue) o;

How to solve this error please help me
Thanks
Please try to replace your ftpDownloadFile method by this
public List<String> ftpDownloadFile() {
return Arrays.asList("A","B","C","D","E","F","G");
}
What it is wrong in your flow? It is because the last payload is an String (request sent by http). In your method you should return a Collection and that would be the payload for the batch:process-records
You should not use a custom component for downloading a file. You can use the FTP component to retrieve the file contents and transform the content to a List so batch would able to process it.

Judging from the top description of the error, I understand the problem to be that Scatter gather does not receive String payloads, even though the current documentation for the component mentions nothing of the sort. Is this correct?
The flow I'm running is fairly simple, receiving a String from an inbound http and trying to route it to a REST service that will use the String to print something (returning text/plain) and to a DB to store the String in a table. Relevant code follows:
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8084" doc:name="HTTP"/>

Trawling through the net I found this old Mule JIRA issue with an exception similar to what I'm getting, but trying out the suggested solution (workaround?) didn't do anything for me: https://www.mulesoft.org/jira/browse/MULE-7594
Something wrong is happening in your route 0.
You are getting a composite routing exception as per documentation:
The CompositeRoutingException is new to the 3.5.0 Runtime. It extends
the Mule MessagingException to aggregate exceptions from different
routes in the context of a single message router. Exceptions are
correlated to each route through a sequential ID.
This exception exposes two methods which allow you to obtain the IDs
of failed routes and the exceptions returned by each route.
The getExceptions method returns a map where the key is an integer
that identifies the index of the failed route, and the value is the
exception itself. The getExceptionForRouteIndex(int) method returns
the exception of the requested route ID.
As you don't have an execption strategy, the toString is call to that exception and that only prints the route failing (that has nothing to do with the fact that the payload is String)
Please use the following exeption strategy to find out exactly what's wrong:
<catch-exception-strategy doc:name="Catch Exception Strategy">
<logger level="ERROR" message="#[exception.exceptions]"/>
</catch-exception-strategy>
