JDBC query theme in a JSP page

Question

Hi, everyone
I tried to write JDBC query theme in a JSP page at MapViewer, but it did not work.
The following is the codes.
1.JDBC theme in a map request in XML
<theme name="jdbc_theme_contour">
<jdbc_query
datasource="spatial10g"
jdbc_srid="8703"
spatial_column="geom"
render_style="C.RED">
Select geom from contour where time='01-JUL-07'
</jdbc_query>
</theme>
2. JDBC theme in a JSP request.
"<theme name=\"jdbc_theme_contour\" >\n" +
" <jdbc_query \n" +
" jdbc_srid=\"" + srid + "\"\n" +
" datasource=\"" + dataSource + "\"\n" +
" spatial_column=\" geom \"\n" +
" render_style=\"C.RED\" >\n" +
" SELECT geom from contour where time='01-JUL-07' \n" +
" </jdbc_query> \n" +
" </theme> \n" +
I do not know whether the second form is right or not. I did not display the JDBC query in MapViewer. Does anyone know the second form is right? or Maybe give me a right form in a JSP request. (contour is a table , geom is the column of geometry attribute in contour)

Hi
Here is the map request in JSP
// Construct a map request
mapRequest = "xml_request=" +
"<?xml version=\"1.0\" standalone=\"yes\" ?>\n" +
"<map_request \n" +
// " title=\"" + title + "\"\n" +
" datasource=\"" + dataSource + "\"\n" +
" basemap=\"" + basemap + "\"\n" +
" width=\"" + width + "\"\n" +
" height=\"" + height + "\"\n" +
" bgcolor=\"#FFFFFF\" >\n" +
" format=\"PNG_URL\" >\n" +
" <center size=\"" + size + "\">\n" +
" <geoFeature>\n" +
" <geometricProperty typeName=\"center\">\n" +
" <Point>\n" +
" <coordinates>\n" +
" " + cx + ", " + cy + "\n" +
" </coordinates>\n" +
" </Point>\n" +
" </geometricProperty>\n" +
" </geoFeature>\n" +
" </center>\n" +
"<themes> \n" +
(flood.equals("true")?
("<theme name=\"jdbc_theme_contour\" >\n" +
" <jdbc_query \n" +
" jdbc_srid=\"" + srid + "\"\n" +
" datasource=\"" + dataSource + "\"\n" +
" spatial_column=\"GEOM\"\n" +
" render_style=\"C.RED\" >\n" +
" SELECT * from contour where time='01-JUL-07' \n" +
" </jdbc_query> \n" +
     " </theme> \n") : "") +
     (waterdepth.equals("true")?
     (" <theme name=\"FLOOD.LINKS\" >\n" +
     " </theme> \n") : "") +
     " <theme name=\"net_theme\" user_clickable=\"false\"> \n" +
" <jdbc_network_query \n" +
" network_name=\"" + networkName + "\"\n" +
" network_level=\"1\" \n" +
" jdbc_srid=\"" + srid + "\"\n" +
" datasource=\"" + dataSource + "\"\n" +
(showlinks.equals("true")?
(" link_style=\"L.CRM_SROADS\"\n") : "") +
(showlinks.equals("true") && showdir.equals("true")?
(" direction_style=\"M.IMAGE105_BW\"\n" +
" direction_position=\"0.75\"\n" +
" direction_markersize=\"" + dirsize + "\"\n") : "") +
(showlinks.equals("true") && showlklabels.equals("true")?
(" link_labelstyle=\"" + lklbstyle + "\"\n" +
" link_labelcolumn=\"link_id\"\n") : "") +
(shownodes.equals("true") ?
(" node_style=\"M.CITY HALL 4\"\n" +
" node_markersize=\"" + nodesize + "\"\n") : "") +
(shownodes.equals("true") && showndlabels.equals("true")?
(" node_labelstyle=\"" + ndlbstyle + "\"\n" +
" node_labelcolumn=\"" + ndlbcolumn + "\"\n") : "") +
(showpath.equals("true") ?
(" path_ids=\"" + pathid + "\"\n" +
" path_styles=\"L.PH\"\n") : "") +
" asis=\"false\"></jdbc_network_query> \n" +
" </theme> \n" +
(runanalysis.equals("true") &&
(algorithm.equals("DIJKSTRA") || algorithm.equals("ASEARCH")) ?
(" <theme name=\"spath_theme\" user_clickable=\"false\"> \n" +
" <jdbc_network_query \n" +
" network_name=\"" + networkName + "\"\n" +
" network_level=\"1\" \n" +
" jdbc_srid=\"" + srid + "\"\n" +
" datasource=\"" + dataSource + "\"\n" +
" analysis_algorithm=\"" + algorithm + "\"\n" +
" shortestpath_style=\"L.DPH\"\n" +
" shortestpath_startnode=\"" + startnode + "\"\n" +
" shortestpath_endnode=\"" + endnode + "\"\n" +
" shortestpath_startstyle=\"M.STAR\"\n" +
" shortestpath_endstyle=\"M.CIRCLE\"\n" +
" asis=\"false\"></jdbc_network_query> \n" +
" </theme> \n") : "") +
"</themes>\n" +
"</map_request>\n";
in this request, other themes and JDBC network query theme work except the JDBC query theme. I guess the style or format in the following are not right.
" spatial_column=\" geom \"\n" +
" SELECT geom from contour where time='01-JUL-07' \n" +
Anyway, I hope you can give me instructions.
