Error description

  • Enabling Probe with Non-XML request type rule and Flow Control
    enabled, if INPUT is not consumed, might result in transaction
    error.
    
    
    Details:
    Non-XML request-type assumes that input gets consumed by a
    Transform Binary Action or by a convert-http action. If that is
    not the case, DataPower just appends INPUT to the output
    generated by rule processing (see slides 15-17 of this WSTE
    webcast:
    http://www-01.ibm.com/support/docview.wss?uid=swg27022979).
    
    Issue exists for Non-XML data getting passed thru and
    Flow Control enabled because INPUT
    has not been consumed for Non-XML request-type with Probe on.
    Problem does not exist on response rule.
    .
    

Local fix

  • If empty output is intended (eg. by NULL--Results--OUTPUT),
    add Transform Binary Action
    INPUT--xformbin(null.xsl)--NULL somewhere in the rule. This will
    avoid the transaction error.
    
    Copy of null.xsl:
    <xsl:stylesheet version="1.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xmlns:dp="http://www.datapower.com/extensions"
      extension-element-prefixes="dp"
    >
      <dp:input-mapping  href="store:///pkcs7-convert-input.ffd"
    type="ffd"/>
    
      <xsl:output omit-xml-declaration="yes" />
    
      <xsl:template match="/">
        <!-- do nothing -->
      </xsl:template>
    
    </xsl:stylesheet>
    

Problem summary

  • Affected is request rule processing with Non-XML request type
    and Flow Control enabled.
    
    With Probe enabled, a transaction might raise an error message.
