Unless you're using Hibernate or iBatis (or any ORM which will create SQL Statements) I would strongly suggest your DBA to place Triggers to validate Data inserts before pushing into DB..(Once the aberrant character is in your DB there is no extracting) I would also suggest incorporating jsp precompile jsp's into your build cycle to catch any misconfigs in tld's here is one courtesy of Glassfish --assumes AS_INSTALL is set to GlassfishDefaultInstallationFolder --assumes AS_JAVA is set to GlassfishJavaDefaultInstallationFolder --assumes AS_ANT_LIB is set to GlassfishAntLibrary @echo off REM REM Copyright 1997-2007 Sun Microsystems, Inc.
