Ok this is probably a JDBC thing but as many admins seem to be running webapps and it is a version migration problem I shall ask here: I have migrated the backend from 7.2.1 to 8.1.1 Most of the JSPs work just fine several others don't §§§§§§§§§§§§§§§§§ org.postgresql.util.PSQLException: ERREUR: Entrée manquante de la clause FROM pour la table «individu» (translation: missing entry in the FROM clause of table...) org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecu torImpl.java:1512) org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImp l.java:1297) org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java: 188) org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Stateme nt.java:430) org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdb c2Statement.java:346) org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2St atement.java:250) org.apache.jsp.contact.fiche_005findividu_005fintra_jsp._jspService(org. apache.jsp.contact.fiche_005findividu_005fintra_jsp:71) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.ja va:322) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) §§§§§§§§§§§§§§§§§§ OK so far so good, now the crunch - I have a newer version of one of the broken pages which uses the exact same JDBC connection code and it works. The only modifications in the new page are use of style sheets for layout instead of tables... I have run the query from the JSP in pgaccess and it works just fine. Tomcat was also updated from 4 to 5.5 and I have the latest postgresql.jar for JDK1.5 Any thoughts?
