I am trying to implement an XSP that uses the following if statement.
This might be extremely simple. I think I remember seeing a URL that in
the User Documentation section that provided an example of code to use
inside an XSP page including a CDATA section. I can't seem to find it
anymore. I simply would like to know how to write the following if
statement with or without a CDATA section. (I've forgotten how the CDATA
section is used also.) Any quick help/reminder would be appreciated.
if( <xsp-session:get-attribute name="state"/> == null &&
<xsp-request:get-parameter name="state"/> == null ){
<field id="state" label="State" type="select"
selection="multiple">
<esql:connection>
<esql:pool>testdb</esql:pool>
<esql:execute-query>
<esql:query>select distinct state from
state_table</esql:query>
<esql:results>
<esql:row-results>
<value><esql:get-string column="state"/></value>
</esql:row-results>
</esql:results>
</esql:execute-query>
</esql:connection>
</field>
}
To document the error, I get the following "Internal server error" page:
