http://issues.apache.org/bugzilla/show_bug.cgi?id=36923 Summary: Deactivated EL expressions are not parsed for jsp expressions/scriptlets/etc Product: Tomcat 5 Version: 5.5.9 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P3 Component: Jasper AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] JavaServer Pages Specification 2.0, section JSP.3.3.2 says: --- Since the syntactic pattern ${expr} was not reserved in the JSP specifications before JSP 2.0, there may be situations where such a pattern appears but the intention is not to activate EL expression evaluation but rather to pass through the pattern verbatim. To address this, the EL evaluation machinery can be deactivated as indicated in this section. [...] The default mode for JSP pages in a Web Application delivered using a web.xml using the Servlet 2.3 or earlier format is to ignore EL expressions; this provides for backward compatibility. --- However, even with deactivated EL expression evaluation, jsp code like: <%@ page isELIgnored="true" %>${<%= "Hello, world!" %>} will produce output like: ${<%= "Hello, world!" %>} which is of course not backwards-compatible with Servlet 2.3 / JSP 1.2 container (e.g., Tomcat 4.x), where the output would be: ${Hello, world!} The ${...} syntax is widely used, and any pre-2.0 jsp pages having it would be incompatible with Tomcat 5.x even though the standard tries to ensure the compatibility. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
