Answer 1

The mulerequester:config is outdated and not necessary anymore.

Remove line:

<mulerequester:config name="Mule_Requester" doc:name="Mule Requester"/>

Instead, create a new file-connector config and reference your mule-requester to this config:

<file:connector name="file-connector" autoDelete="false" streaming="true" validateConnections="true" doc:name="File"/>
<flow...>
   ...
<mulerequester:request resource="file://src/main/resources/somefile.txt?connector=file-connector" doc:name="Retrieve File" />
</flow>

This should deploy your app without problems.

NOTE: the file-connector config contains all the settings that you need to modify in order to read the proper folder, etc ...

Answer 2

Many people face this error when they are using various connectors,So I want to given an answer which is helpful to all.When you get this particular error "Invalid content was found starting with element" it means the Jar is not available.whatever connector you use(netsuite,zuora,salesforce,mulerequester etc) if you get this error just right click on the connector and give add libraries to the project and it will fix the issue.
