ESQL Problem in 2.1.3

Corey Keith Wed, 19 Nov 2003 15:24:09 -0800

The recent changes in xsp.xsl in 2.1.3 seem to be breaking the esql logicsheet or they are uncovering a bug in the esql logic-sheet. ESQL is pretty much broken in 2.1.3 for me. Can someone forward to the dev list?

Thanks,

Corey

1.3 xsp.xsl

<xsl:template match="text()">
    <xsl:choose>
      <xsl:when test="namespace-uri(..) = $xsp-uri and (local-name(..) = 'logic' or local-name(..) = 'expr')">
        <xsl:value-of select="."/> <!---        This change ?>
      </xsl:when>
      <xsl:otherwise>
        this.characters("<xsl:value-of select="XSLTExtension:escape($extension, .)"/>");
      </xsl:otherwise>
    </xsl:choose>
</xsl:template>

1.4 xsp.xsl

<xsl:template match="text()">
    <xsl:choose>
      <xsl:when test="namespace-uri(..) = $xsp-uri and (local-name(..) = 'logic' or local-name(..) = 'expr')">
        <xsl:value-of select="XSLTExtension:escape($extension, .)"/>    <!---        This change ?>
      </xsl:when>
      <xsl:otherwise>
        this.characters("<xsl:value-of select="XSLTExtension:escapeJava($extension, .)"/>");
      </xsl:otherwise>
    </xsl:choose>
</xsl:template>

Causes the following xsp:

<xsp:page language="java" xmlns:xsp="http://apache.org/xsp" xmlns:esql="http://apache.org/cocoon/SQL/v2">
<database>
  <esql:connection>
   <esql:pool>natlib</esql:pool>
   <esql:execute-query>
    <esql:query>SELECT * FROM Core WHERE DigitalID=100006111</esql:query>
    <esql:results>
     <esql:row-results>
      <row>
       <esql:get-columns/>
      </row>
     </esql:row-results>
    </esql:results>
    <esql:no-results>No results</esql:no-results>
    <esql:error-results>Error in query</esql:error-results>
   </esql:execute-query>
  </esql:connection>
</database>
</xsp:page>

Which produces: (note the nested xsp:logic elements)

...

<xsp:logic>
<xsp:logic>private Stack _esql_connections = new Stack();

    private Cocoon2EsqlConnection _esql_connection = null;
    private Stack _esql_queries = new Stack();
    private AbstractEsqlQuery _esql_query = null;
    private SQLException _esql_exception = null;
    private StringWriter _esql_exception_writer = null;

    </xsp:logic>
            private static ComponentSelector _esql_selector = null;

            protected ComponentSelector _esql_get_selector() throws org.apache.avalon.framework.component.ComponentException {
              if (_esql_selector == null) {
                try {
                  _esql_selector = (ComponentSelector) manager.lookup(DataSourceComponent.ROLE + "Selector");
                } catch (ComponentException cme) {
                  getLogger().error("Could not look up the datasource component", cme);
                }
              }
              return _esql_selector;
            }

            protected void _esql_printObject ( Object obj, AttributesImpl xspAttr) throws SAXException
            {
               if ( obj instanceof List) {
           ListIterator j=((List)obj).listIterator();

    <xsp:element name="sql-list">
      <xsp:logic>
                       while (j.hasNext()){

        <xsp:element name="sql-list-item">
          <xsp:attribute name="pos">
            <xsp:expr>j.nextIndex()</xsp:expr>
          </xsp:attribute>
          <xsp:logic>this._esql_printObject(j.next(),xspAttr);</xsp:logic>
        </xsp:element>
                       };

Which results in java all messed up:

   /**
    * Generated by XSP. Edit at your own risk, :-)
    */
   public class query_xsp extends XSPGenerator {

// Files this XSP depends on
private static File[] _dependentFiles = new File[] {

};

       // Initialize attributes used by modifiedSince() (see AbstractServerPage)
       {
           this.dateCreated = 1069271463674L;
           this.dependencies = _dependentFiles;
       }

       /* Built-in parameters available for use */
       // context    - org.apache.cocoon.environment.Context
       // request    - org.apache.cocoon.environment.Request
       // response   - org.apache.cocoon.environment.Response
       // parameters - parameters defined in the sitemap
       // objectModel- java.util.Map
       // resolver   - org.apache.cocoon.environment.SourceResolver

       /* User Class Declarations */
       private Stack _esql_connections = new Stack();
   private Cocoon2EsqlConnection _esql_connection = null;
   private Stack _esql_queries = new Stack();
   private AbstractEsqlQuery _esql_query = null;
   private SQLException _esql_exception = null;
   private StringWriter _esql_exception_writer = null;

/ Something is missing !!!!

   this.contentHandler.startElement(
     "",
     "sql-list",
     "sql-list",
     xspAttr
   );

xspAttr.clear();

   xspAttr.addAttribute(
     "",
     "pos",
     "pos",
     "CDATA",
     String.valueOf(j.nextIndex())
   );

   this.contentHandler.startElement(
     "",
     "sql-list-item",
     "sql-list-item",
     xspAttr
   );

xspAttr.clear();
