Bug with symbolic links in WEB-INF/lib/

[Frédérik Bilhaut]

Hi !

I noticed a Tomcat bug that may be of interest for you developers. When using Tomcat 4.0.x, I used to set some symbolic links in my WEB-INF/lib directory. For example :

WEB-INF/lib/mm.mysql.jar => /usr/java/lib/mm.mysql-xx.x/mm.mysql.jar

But this won't work with Tomcat 4.1.12, which throws the following exception when deploying :

java.lang.IllegalArgumentException:
Invalid TLD resource path /WEB-INF/lib/mm.mysql.jar
at org.apache.catalina.startup.ContextConfig.tldScanJar
(ContextConfig.java:898)

It took a while to figure out what happened, so maybe a note in RELEASE-NOTES would be usefull to many people :o)

Best regards,
