Issue/Introduction

We are using  APM 10.7.0.197 Java agent with Websphere and need to prevent SOAP header manipulation by the agent

The following property values were set

com.wily.introscope.agent.soapheaderinsertion.enabled=false
com.wily.introscope.agent.soapheaderread.enabled=false
com.wily.introscope.agent.httpheaderinsertion.enabled=false
com.wily.introscope.agent.httpheaderread.enabled=false

but the SOAP header still had the correlation id inserted causing the application to fail and we are seeing the following error in the application which sows the header is present

XSD: [ParserException]: The following errors occurred during the XSD check of the sent XML message: 
Line: 1 - Position: 251 - Could not find schema information for the element 
'http://www.ca.com/apm:WSCorIDSOAPHeader'. # Line: 1 - Position: 299 - Could not find schema information 
for the attribute 'CorID'. [ParserError=XSD, RawData=<soapenv:Envelope 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance"><soapenv:Header>
<WSCorIDSOAPHeader xmlns=http://www.ca.com/apm CorID="96AD3D29AC138310B86D32CE7098395D,1:1,0,0

 

Cause

Not all tracers adhere to the property settings and need to be manually disabled

Environment

Release : 10.7.0

Component : Introscope

Resolution

The SOAP header insertion was prevented by commenting the following tracer in spm-correlation.pbd 

TraceOneMethodWithParametersIfFlagged: ApacheCXFJaxWSClientTracing invokeSync(Ljava/lang/reflect/Method;Lorg/apache/cxf/service/model/BindingOperationInfo;[Ljava/lang/Object;)Ljava/lang/Object; ApacheCXFJaxWSSyncClientCorrTracer "WebServices"

 

A defect has been raised for the tracer to be corrected to observe the property settings
