how to rejected request missing header or wrong header in wso2

I have code in API WSO2 like this
<api context="/request" name="Request" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET" uri-template="/Executionreport/{vtid}/{token}">
<inSequence>
<property expression="get-property('uri.var.vtid')" name="Vtid" scope="default" type="STRING"/>
<property expression="get-property('uri.var.token')" name="token" scope="default" type="STRING"/>
<filter regex="1234" source="$ctx:token">
<then>
<log>
<property name="sukses masuk token" value="0"/>
</log>
<sequence key="select_Execution_report"/>
<property name="messageType" scope="axis2" type="STRING" value="application/json"/>
</then>
<else/>
</filter>
</inSequence>
<outSequence/>
<faultSequence/>
</resource>
</api>
so for this request I will use like this one
http://localhost:8280/request/Executionreport/1100/1234
so if the token is wrong I will replay this one
HTTP/1.1 200 OK
soapaction: urn:mediate
Host: localhost:8280
Accept-Encoding: gzip,deflate
cache-control:
Content-Type: application/json; charset=UTF-8
Date: Thu, 23 Jul 2020 07:51:59 GMT
Transfer-Encoding: chunked
Connection: Keep-Alive
{ "status":"401 Not Authenticated" }
i want to change the logic like the request is like
http://localhost:8280/request/Executionreport/1100 with methods GET and have header token=1234
so if token wrong in header request wso2 will rejected so status will be HTTP/1.1 401 unauthorized.
so my question how to create API methods GET and need header in WSO2 ?

You can read the incoming header as below.
<property name="Token" expression="get-property('token')" scope="transport" type="STRING" />
Based on that you can perform any action.

Sending message on wso2 socket, getting exception

I am trying to send a message over TCP in wso2 framework. I am getting this exception in log:
[2015-08-20 12:21:50,098] ERROR - TCPWorker Error while processing TCP request through the Axis2 engine

And wso2.xml:

</outSequence>
</target>
<parameter name="transport.tcp.port">6060</parameter>
<parameter name="transport.tcp.contentType">application/xml</parameter>
<description/>

</definitions>

It sounds like no proxy service can be found in the ESB when a message is received on tcp port 6060.
I'm not used to tcp transport in WSO2 but I wonder if the "transports" attribute in you proxy definition should contain "tcp" instead of "https,http" :
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="TCPProxy"
transports="tcp"
statistics="disable"
trace="disable"
startOnLoad="true">
<target>
<inSequence>
<log level="full"/>
</inSequence>
<outSequence>
<send/>
</outSequence>
</target>
<parameter name="transport.tcp.port">6060</parameter>
<parameter name="transport.tcp.contentType">application/xml</parameter>

Facing "unqualified type in strict mode for: MessageExchangePattern" while trying to integrate Mule with Drools

i am trying to integrate mule with drools, i have mainly followed the tutorial here but i am getting this error :
(1,22) unqualified type in strict mode for: MessageExchangePattern
(1,30) unqualified type in strict mode for: ONE_WAY '
it seems impossible to find the solution to me, can any one help me? thanks.
this is my .drl file :
global org.mule.module.bpm.MessageService mule;
import com.hamgam.hit.esb.*;
rule "La Vita Ebela"
dialect "mvel"
when
$x:XMLDTO( inputXML == "inputXML" )
then
mule.generateMessage("emc", "KeyValueMatched", null, MessageExchangePattern.ONE_WAY);
end
and this is mules flow :

You need to:
import org.mule.MessageExchangePattern
Otherwise your Drools MVEL script will have no idea what MessageExchangePattern.ONE_WAY is.

Issue with XSLT Transformation using WSO2 ESB

I struggling with XSLT transformer mediator using XSLT mediator in wso2 esb 4.8.1.
The xslt is :

What may be the cause of the exception if the XSLT transformation is working fine in other tool ?

The key in the proxy is correct. I might have pasted the wrong XML proxy,

Local entry:

There was a problem with the local entry. Finally, I was able to fix this issue by adding a local entry like this in the synapse config
<localEntry key="xslt99">
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="//ns:getResponse"/>
</xsl:template>
<xsl:template match="ns:getResponse">
<ep:credit xmlns:ep="http://ep.service.ims.com" xmlns:xsd="http://ep.service.ims.com/xsd">

Initially I was trying to add the local entries like this
<localEntry xmlns="http://ws.apache.org/ns/synapse" key="xslt1" src="file:resources/creditproxy/personToCredit.xslt"></localEntry>
But still I don't know how to specify a xslt file in local entry.?

Sending an simple E-mail using WSO2 ESB

I am trying to send an e-mail to a specific address using WSO2 ESB.
I configured my axis2.xml by applying following settings to mailto transport sender.
<transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
<parameter name="mail.smtp.host">smtp.gmail.com</parameter>
<parameter name="mail.smtp.port">587</parameter>
<parameter name="mail.smtp.starttls.enable">true</parameter>
<parameter name="mail.smtp.auth">true</parameter>
<parameter name="mail.smtp.user">myusername#gmail.com</parameter>
<parameter name="mail.smtp.password">mypassword</parameter>
<parameter name="mail.smtp.from">myusername#gmail.com</parameter>
</transportSender>
This is my fragment of the sequence which is responsible for sending mail.
<log level="custom">
<property name="Mail status" value="===============enter the mail============="/>
</log>
<property name="messageType" value="text/html" scope="axis2"/>
<property name="ContentType" value="text/html" scope="axis2"/>
<property name="Subject" value="File Received" scope="transport"/>
<property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
<log level="full"/>
<send>
<endpoint>
<address uri="mailto:myreciveemail#gmail.com"/>
</endpoint>
</send>
<log level="custom">
<property name="flag" value="=====After======="/>
</log>
I am pretty much sure that other parts of my proxy service are working just fine.
But the problem is when I triggered the proxy service, it is going through all parts of the sequence without throwing an error but not sending the mail
This is my console output relevant to the fragment of sequence I stated earlier.

Guys please any one knows what's the issue is????

Try to use
<parameter name="mail.smtp.user">myusername</parameter>
without #gmail.com

For those of you who are trying to send an email using the configuration stated in the question via wso2 esb, apart from all that you will need to include a axis2-transport-mail-1.0.0.jar under wso2esb-5.0.0\repository\axis2\client\lib. This jar contains the classes necessary for axis2 to send out an email. Hope this helps someone.
