Re: taglibs
OK, so I tried that and found one library needs to be excluded (from the exclusion list) - i.e. scanned # ls jstl*; grep ".tld" jstl-* jstl-api-1.2.jar jstl-impl-1.2.jar Binary file jstl-impl-1.2.jar matches So if your rule works, I need jstl-impl to be scanned, but jstl-api could be excluded. Nice! Thanks. Ray On Monday, November 6, 2017 10:54 AM, Mark H.

So... generally speaking I would say "you should know your own libraries" but it shouldn't be hard to determine which libraries are taglibs. Simply look in each JAR file to see if there are any ".tld" files. Some libraries include tag libraries that your application doesn't care about, though, and you may be able to skip JAR scanning for those JARs if you know enough about their use by your application. - -chris -BEGIN PGP SIGNATURE- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAloAfCYACgkQHPApP6U8 pFg/Rw//d7uXPFuCTucg9E9zGbb4mvO9pfvz+s8YLg81Z5l9b+sDvyWGpYsT9lLg OuOqoX7jJBR2fkwKZ2xaicviuHN+u+GHTHbJjkktf+U7yv6VUNo6ZOnZBeCQOLjV XFMXsxZl6q5o5Gn5jFBVjykqZUZSxlL98lDFJuzm7ut3wtqB/CD0ttGsHsXXBq+u fC4jJUYzYltRR0oYw161fwRfWQ/EqFtYObZCohTvVtByO5Vh3aKHyg8s7cRqLV+7 dz/qhwmXGEvWPiQrNjcZcUEBxXymYOSCspXtX/BaWJH5vL/I78CrjgrjzzrHpz9O w77TlYxgDe5vgRxItrHUv3Omn4QKEYTzxUKrsUpRIghquDg7UL9VqD0bSKi6Njfb 5rX+00Btt4EbRGaqfNFpDNOfbDZat8Ktk6Og6Me/SbZi/AFQrggoc+CFDSjKvHeJ B3B8OWjexnzvaZiJ3RybO3wuPDF63Z3Sqx1JVL6JVVYi4USFj0Nf8kXGL7PcZjHu VdxA/spAKEojzDB6vxquO5FL4VwI2T+r+4nzkp5cnFtcPj79L+B30p1Q9HGmvAQD 4i3ez+u1Hh36Wf8oovMj3v3dzesEE459kpM3Yag44vs6y6CGtuHglDArJt7BC08D 4YrQdT9r+c/pnzeV+lOTivD0vfvUdRcklJVNYQ+6jJ/n/UkCjl0= =NUyW -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: taglibs
Chris, I am not the primary developer. I do Java and DB development. I leave the JSP for someone else (I am mostly retired but I have been doing this a LONG time). But I deal with distributions and builds so I was the one who modified the "not to SCAN" libraries.2.5 minutes down to less than 1 second.But I blew it with the jstl jars so I just wanted to know if there is any way to find out if the jar is a taglib. I don't think we use Maven.

Re: Taglibs ; error in a JSP using expression langluage
Thanks all for your advice.
My web.xml has an entry:
!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd";>
which, I think, caused the error.
I have inserted the line:
<%@ page ... isELIgnored="false" %>
as Pid suggested and the error disappeared.
Thanks a lot.

It seems to me that Tomcat could not interpret the JSP. My question is,
do I miss some libraries? Do My application runs on Linux Debian,
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
(j2sdk1.5-sun).
The taglibs jstl.jar and standard.jar stem from
jakarta-taglibs-standard-1.1.2.
Thanks a lot for your help.
