I am attempting to port a Tomcat/MySql application from OSX to Windows 7 (I previously ported it from Vista to OSX, so it shouldn't be as difficult as it sounds), and am having problems with back-compatibity on some queries.
The application works correctly on OSX, with Tomcat 5.5, JRE 1.5.0 R12, Tomcat JDK 4 Compatibility Pack, J/Connector 5.1.14 and MySql 5.0. On Windows 7, my configuration is Tomcat 5.5.34, JRE 1.6.0 R26, J/Connector 5.1.18, MySql 5.5. (I tried both with and without the JDK 4 Compatibility pack and it doesn't make a difference). The following test JSP shows the problem: <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Test</title> </head> <body> <h1>Results</h1> <sql:query var="rsImages" dataSource="jdbc/Images"> SELECT i.imageID,i.DateDay,i.DateMonth,i.DateYear,i.Location1,i.Location2,i.ScannedYN,c.description AS country,sd1.description AS Subject, sdt.fieldtypeid, sdt.lookuptablename FROM image_tbl i, lu_country_tbl c, xrf_image_subject_tbl si, subject_tbl s, subject_detail_tbl sd1, lu_subject_detail_type_tbl sdt WHERE (i.countryID=c.CountryID) AND (si.SubjectID=s.SubjectID) AND (si.ImageID=i.ImageID) AND (s.SubjectID=sd1.subjectID) AND (sd1.subjectdetailtypeid=sdt.subjectdetailtypeid) AND (sd1.subjectdetailtypeid IN (1,2,6,8,9,13)) and i.imageid=20002 </sql:query> ID: ${rsImages.rows[0].ImageID}<br> Location: ${rsImages.rows[0].Location1}<br> Country: ${rsImages.rows[0].country}<br> Subject: ${rsImages.rows[0].subject}<br> Description: ${rsImages.rows[0].Description}<br> ID: ${rsImages.rows[1].ImageID}<br> Location: ${rsImages.rows[1].Location1}<br> Country: ${rsImages.rows[1].country}<br> Subject: ${rsImages.rows[1].subject}<br> Description: ${rsImages.rows[1].Description}<br> </body> </html> When running this page, ID, Location and Description are all returned with values. However, country and Subject are not returned at all. You will note that country and Subject are both aliased in the query. Description is not a directly requested in the query, but is returning the contents of sd1.description. I seem to recall having a similar issue when first porting to OSX and having to set backward compatibility somewhere, but can't find my records for this anywhere. Anyone got any ideas?
