Error description

• After upgrading from CICS TS 5.6 to 6.1 the following error is
  seen :
  
  CWWKF0033E: The singleton features servlet-3.1 and servlet-3.0
  cannot be loaded at the same time.  The configured features
  servlet-3.1 and
  cicsts:com.ibm.cics.wlp.defaultApp1.0-appSecurity2.0
  include one or more features that cause the conflict. Your
  configuration is not supported; update server.xml to remove
  incompatible features.
  
  This occurs when the following three features are enabled:
  <feature>servlet-3.1</feature>
  <feature>cicsts:defaultApp-1.0</feature>
  <feature>cicsts:security-1.0</feature>
  

Local fix

• set -Dcom.ibm.cics.jvmserver.wlp.defaultapp=false to
  remove the defaultapp

  ****************************************************************
  When the following three features are set in a Liberty
  JVMSERVER's server.xml:
  <feature>servlet-3.1</feature>
  <feature>cicsts:defaultApp-1.0</feature>
  <feature>cicsts:security-1.0</feature>
  
  The following error is encountered:
  CWWKF0033E: The singleton features servlet-3.1 and servlet-3.0
  cannot be loaded at the same time.
  The configured features servlet-3.1
  and cicsts:com.ibm.cics.wlp.defaultApp1.0-appSecurity2.0
  include one or more features that cause the conflict.
  Your configuration is not supported; update server.xml
  to remove incompatible features.
  
  The following can also be observed:
  FFDC1015I: An FFDC Incident has been created:
  "java.lang.IllegalArgumentException: Unable to load conflicting
  versions of features "com.ibm.websphere.appserver.servlet-3.1"
  and "com.ibm.websphere.appserver.servlet-3.0".  The feature
  dependency chains that led to the conflict are:
  com.ibm.websphere.appserver.servlet-3.1 and
  com.ibm.cics.wlp.defaultApp1.0-appSecurity2.0 ->
  com.ibm.wsspi.appserver.webBundleSecurity-1.0 ->
  com.ibm.wsspi.appserver.webBundle-1.0 ->
  com.ibm.websphere.appserver.servlet-3.0
  com.ibm.ws.kernel.feature.internal.FeatureManager reportErrors"
  at ffdc_25.02.18_10.51.53.0.log.
  
  servlet-3.1 is then installed and th
  e JVMSERVER enables
  successfully.
  Note: The defaultapp will be added to server.xml if the JVM
  Profile contains option:
  -Dcom.ibm.cics.jvmserver.wlp.defaultapp=true
  

Problem conclusion

• UI98245
  
  CICS has been updated so that the feature cicsts:defaultApp-1.0
  can detect and use servlet-3.1 for its dependencies to prevent
  the CWWKF0033E.
