The WMS GetFeatureInfo operation in the text/plain format returns a http 400 error when no features are found.

Additional Information

Workaround

The file “featureinfo_text_plain.xsl” under “...\ArcGIS\Server\framework\runtime\ArcGIS\Resources\Styles\WMS” was adapted to also receive a response in the case of features not found. The file was modified as follows:

<?xml version="1.0" encoding="ISO-8859-1"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:esri_wms="http://www.esri.com/wms" xmlns="http://www.esri.com/wms">

  <xsl:output method="text" indent="no" encoding="ISO-8859-1" omit-xml-declaration="yes"/>

  <xsl:variable name="newline">

    <xsl:text>

    </xsl:text>

  </xsl:variable>

  <xsl:template match="/">   

    <xsl:choose>

      <xsl:when test="esri_wms:FeatureInfoResponse/esri_wms:FeatureInfoCollection">

        <xsl:for-each select="esri_wms:FeatureInfoResponse/esri_wms:FeatureInfoCollection">@<xsl:value-of select="@layername"/><xsl:value-of select="$newline"/>

          <xsl:for-each select="esri_wms:FeatureInfo[1]/esri_wms:Field"><xsl:value-of select="esri_wms:FieldName"/>;</xsl:for-each><xsl:value-of select="$newline"/>

          <xsl:for-each select="esri_wms:FeatureInfo">

            <xsl:for-each select="esri_wms:Field"><xsl:value-of select="esri_wms:FieldValue"/>;</xsl:for-each><xsl:value-of select="$newline"/>

          </xsl:for-each>

        </xsl:for-each>

      </xsl:when>

      <xsl:otherwise>

        <xsl:text>The request is not allowed.</xsl:text>

      </xsl:otherwise>

    </xsl:choose>

  </xsl:template>

</xsl:stylesheet>
