Hi,
 
I can add that we are successfully running Grouper 1.4 API,
UI, and WS on this platform:

[root@oregano
 ~]# cat /etc/issue
CentOS release 5.2 (Final)
Kernel \r on an \m

[root@oregano
 ~]# java -version
java version "1.6.0_0"
IcedTea6 1.3.1 (6b12-Fedora-EPEL-5) Runtime Environment (build
1.6.0_0-b12)
OpenJDK 64-Bit Server VM (build 1.6.0_0-b12, mixed mode)
[root@oregano
 ~]# rpm -qa | grep tomcat
tomcat5-server-lib-5.5.23-0jpp.7.el5.x86_64
tomcat5-webapps-5.5.23-0jpp.7.el5.x86_64
tomcat5-jasper-5.5.23-0jpp.7.el5.x86_64
tomcat5-common-lib-5.5.23-0jpp.7.el5.x86_64
tomcat5-5.5.23-0jpp.7.el5.x86_64
tomcat5-servlet-2.4-api-5.5.23-0jpp.7.el5.x86_64
tomcat5-jsp-2.0-api-5.5.23-0jpp.7.el5.x86_64
tomcat5-admin-webapps-5.5.23-0jpp.7.el5.x86_64

The class HooksContext is definitely found in the grouper.jar
that Grouper WS is using:

[root@oregano
 grouper-ws]# jar -tf WEB-INF/lib/grouper.jar | grep HooksContext
edu/internet2/middleware/grouper/hooks/beans/HooksContext$1.class
edu/internet2/middleware/grouper/hooks/beans/HooksContext.class
edu/internet2/middleware/grouper/hooks/beans/HooksContext.java

Not being a Java/Tomcat expert, here are my instructions for
how I deployed Grouper WS. These are probably not clever or a
best practice, but it worked:

    * su - tomcat
    * cd /opt/grouper
    * wget 
http://middleware.internet2.edu/dir/groups/grouper/grouper/1.4.0/grouper-ws-1.4.0.tar.gz
    * tar -zxf grouper-ws-1.4.0.tar.gz
    * ln -s grouper-ws-1.4.0 grouper-ws
    * cd grouper-ws/grouper-ws
    * ant dist
    * Change to the directory 
/opt/grouper/grouper-ws/grouper-ws/build/dist/grouper-ws/WEB-INF/classes and 
do the following:
          o copy the file 
/opt/grouper/grouper/conf/grouper.hibernate.properties into the directory, 
replacing the default. Do not symlink as it will not be followed by Tomcat.
          o copy the file /opt/grouper/grouper/conf/grouper.properties into 
the directory, replacing the default. Do not symlink as it will not be 
followed by Tomcat.
          o copy the file /opt/grouper/grouper/conf/sources.xml into the 
directory, replacing the default. Do not symlink as it will not be followed 
by Tomcat.
          o Edit the file log4j.properties and replace ${grouper.home} with 
/opt/grouper/grouper-ws/grouper-ws/build/dist/grouper-ws/WEB-INF/classes/. 
    * Change to the directory 
/opt/grouper/grouper-ws/grouper-ws/build/dist/grouper-ws/WEB-INF/lib and do 
the following:
          o Delete the file mysql-connector-java-5.1.5-bin.jar.
          o copy the file 
/opt/grouper/grouper/lib/custom/mysql-connector-java-5.1.7-bin.jar into the 
directory. 
    * Create the file /etc/tomcat5/Catalina/localhost/grouper-ws.xml with 
contents

      <Context path="/grouper-ws"
docBase="/opt/grouper/grouper-ws/grouper-ws/build/dist/grouper-ws"
         debug="0" privileged="false" reloadable="false"
swallowOutput="true" />

    * Edit the file /etc/httpd/conf.d/proxy_ajp.conf and add the line

      ProxyPass /grouper-ws/ ajp://localhost:8009/grouper-ws/

    * Edit the file /etc/tomcat5/tomcat-users.xml and add these two lines:

      <role rolename="grouper_user"/>
      <user username="GrouperSystem" password="XXXXXXXX"
roles="grouper_user"/>

    * Restart both tomcat5 and Apache httpd.
    * Test the Grouper WS by opening up your web browser and  browsing to
     https://FQDN/grouper-ws/services/GrouperService?wsdl.

     When prompted for a login and password enter
     GrouperSystem and the password you set above. You should
     see the XML document that describes the Grouper WS
     interface in WSDL (web services description language). 

HTH,

Scott
