Last time when i tried to install Tomcat6 from JPackage Repository using yum, it prompts the following error.


 

It seems that the /usr/bin/rebuild-security-providers cannot be found. So i check which package provides this bin.

• yum provides /usr/bin/rebuild-security-providers

Install the jpackage-utils-1.7.3-1jpp.2.el5.noarch

• yum install jpackage-utils-1.7.3-1jpp.2.el5.noarch

Now u should be able to install the Tomcat6

• yum install tomcat6

Reference: jpackage-utils provides rebuild-security-providers and thus prevents using jpackage

Done =)
