Is there a way to call a stored proc from the web in Oracle 10g?

Question

I've found an article about Native Oracle XML DB Web Services in 11g, but it appears to be a new feature. Is there any way of accomplishing something similar in 10g? I would like to be able to process XML documents that contain the name and parameters of the stored proc/function to execute.

I agree with you. I was looking into mod_plsql, but it turns out that their development standards include not using Oracle HTTP server. The whole reason why they want to be able to execute a stored proc based on what is specified in an XML doc is that they want to avoid having to change their middle-tier configurations anytime a new stored proc or a change in stored proc parameters is made. I'm not familiar with what all is involved with .NET and the middle-tier, but supposedly this way, they can specify any stored procedure name and its parameters in an XML file. The XML is then suppose to be passed on to an Oracle stored procedure which will parse the XML and dynamically execute the stored procedure that was specified in the XML.
Here is an example of the XML:
'<Root>
  <PackageName>TEST_PKG</PackageName>
  <ProcedureName>TEST_PROC</ProcedureName>
    <Parameters> 
    <Parameter>
        <Name>EmpID</Name>
        <Value>12345</Value>
    </Parameter>
    <Parameter>
        <Name>Org</Name>
        <Value>ABC</Value>
    </Parameter>
    </Parameters>
</Root>I basically need to parse out the pkg/proc names:
  SELECT t.COLUMN_VALUE.extract('//PackageName/text()').getstringval() PkgName,
         t.COLUMN_VALUE.extract('//ProcedureName/text()').getstringval() ProcName
     INTO v_pkg_name, v_proc_name
     FROM TABLE(xmlsequence(XMLTYPE(v_XML_input) .extract('/Root'))) t;...and then execute the procedure:
    EXECUTE IMMEDIATE 'BEGIN '||v_pkg_name||'.'||v_proc_name||'(:a, :b, :c); END;'
      using in v_in_param1, v_in_param2, out v_XML_output;The problem is that this approach is very complicated since there can be any number of IN/OUT parameters and of various datatypes. I would have to create all kinds of possible bind variables!
