IdP 2.4.5 does not work on recent Tomcat 7 and its workaround

[Takeshi NISHIMURA]

Hi all,

I have an error when running Shibboleth IdP 2.4.5 on recent Tomcat 7.

CentOS 5.11
java-1.6.0-openjdk-1.6.0.39-1.13.11.0.el5_11
Shibboleth IdP 2.4.5
Tomcat 7.0.69 - NG
Tomcat 7.0.68 - NG
Tomcat 7.0.67 - NG
Tomcat 7.0.65 - OK

The error log is attached at the end of this mail.
It also produces a similar error with OpenJDK 7.

If you delete the first slash character in the classpath: URI, it will work as expected.
e.g. "classpath:/schema/shibboleth-2.0-services.xsd" to "classpath:schema/shibboleth-2.0-services.xsd"

There are many classpath: URIs in the following files so you should modify all the URIs.
service.xml
opensaml-2.6.6.jar
shibboleth-common-1.4.5.jar
shibboleth-identityprovider-2.4.5.jar
xmltooling-1.4.6.jar

I think this behavior may be affected by this fix:
