Could you please let me know what I have missed out?

I am trying to read message from activeMQ Queue. It is dequeuing at ActiveMQ but I am unable to read it at backend. Can anyone guide how to read/print the data on my Local Machine ?
Following is the code:
<proxy name="Listen_Queue" startOnLoad="true" transports="jms" xmlns="http://ws.apache.org/ns/synapse">
<target>
<inSequence>
<log level="full">
<property name="MSG" value="Receiving messages from Queue" />
</log>
<property action="set" name="OUT_ONLY" value="true"/>
<drop />
</inSequence>
<faultSequence />
</target>

<parameter name="redeliveryPolicy.redeliveryDelay">2000</parameter>
<parameter name="transport.jms.ContentType">json</parameter>
<parameter name="transport.jms.ConnectionFactory">myQueueListener</parameter>
<parameter name="transport.jms.CacheLevel">consumer</parameter>
When I run the server of Wso2 MI I get this error too:
Unknown error processing message org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxUnexpectedCharException:
Unexpected character '{' (code 123) in prolog; expected '<'

Amyleads would mean a lot.
Change the content type parameter to below.
<parameter name="transport.jms.ContentType">application/json</parameter>
I've set up NLog in an ASP.NET Core MVC application using the examples in the documentation. Logging to a file (target=file) works without any problems.
However, logging to the Sqlite database results in an exception:
2018-10-30 20:04:41.4394 Error DatabaseTarget(Name=db): Error when
writing to database. Exception: System.InvalidOperationException: Must
add values for the following parameters: #MachineName, #Logged,
#Level, #Message, #Logger, #Callsite, #Exception at

behavior) at Microsoft.Data.Sqlite.SqliteCommand.ExecuteNonQuery()
at NLog.Targets.DatabaseTarget.WriteEventToDatabase(LogEventInfo
logEvent) at NLog.Targets.DatabaseTarget.Write(LogEventInfo
logEvent)
Any ideas why the values of these parameters are empty? Or maybe the parameters are not passed at all?

Unable to fix the issue using Microsoft.Data.Sqlite I switched to using System.Data.SQLite (NuGet) instead, which fixed the issue right away.
Remove the Microsoft.Data.Sqlite reference and add a reference System.Data.SQLite (1.0.109.2 at the time of writing) in your .csproj file. Update the dbProvider attribute value in nlog.config to System.Data.SQLite.SQLiteConnection, System.Data.SQLite and you're set.

<target xsi:type="Database"
name="db"
dbProvider="System.Data.SQLite.SQLiteConnection, System.Data.SQLite"

I am working on Cache Mediator in wso2esb. My requirement is to get Hash Digest value generated by org.wso2.carbon.mediator.cache.digest.DOMHASHGenerator class in this mediator.
<sequence name="In_Seq" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
<cache collector="false"

<onCacheHit/>
<implementation maxSize="1000" type="memory"/>
</cache></sequence>
<sequence name="Out_Seq" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
<cache collector="true" id="MyCache" scope="per-host"/>
</sequence>
Can you tell me how to do that?

I stuck with this for Four days...is there any one out there who can help me....
It was given providerName="System.Data.EntityClient" in connection string and i changed that to providerName="System.Data.SqlClient"
I can just add that if you already used EntityFramework you cannot simply change the provider in your connection string, as your Entity will not work. You can add another connection string for your error logging with providerName="System.Data.SqlClient".
We have been testing the message processors and queues on wso2 esb. We have been using the sampling processor quite successfully to just log data to a DB. This POX end to end. The sampling processor correctly dequeues a message and sends it to the endpoint. The endpoint is defined as POX and non-chunked, and all this works well.
We decided to try the store and forward processor as we wanted to test out the guaranteed delivery mechanism. So we created a new processor and defined it as store and forward. In the main sequence that stores the message, we added the target.endpoint property before storing the message. The property was set to the same endpoint that was being used in the sampling scenario.
However - what have found is that in this mode, the message transformation does not happen correctly. The content type is set to text/html and the output is chunked. This causes our service to return a 415 error.
We have tried adding messageType, contentType etc to multiple place, to the axis http sender transport, etc, but it seems to make no difference at all.
Any guidance on this would be appreciated
Define the following property in the sequence before sending to the endpoint
<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>
The JS code below simply inserts the messageID into the return payload to the caller. Using this with a sampling processor and sequence that simply sends to the same endpoint works fine.
