I just upgraded from grouper-1.3.0 to 1.3.1 and tried to do my best to merge configuration changes and additions into existing config files. Two problems arise with 1.3.1 version under Tomcat 5.5.26:

1) When I log in (using HTTP server authentication), the main page only displays the red text "Error!" and 'view source' tells:



<span class="jspError">Error!</span>

<!-- JspException:ServletException in '/WEB-INF/jsp/MyGroups.jsp':
ServletException in '/WEB-INF/jsp/browseStems.jsp': null -->


2) When I (re)deploy grouper, the following kind of warning message will be
written into syslog(8):

Sep 23 19:49:08 localhost Grouper: INFO: JDBCSourceAdapter: JDBC driver loaded. Sep 23 19:49:08 localhost Grouper: INFO: JDBCSourceAdapter: Data Source initialized. Sep 23 19:49:08 localhost Grouper: INFO: JNDISourceAdapter: Success in connecting to LDAP Sep 23 19:49:10 localhost Grouper: WARN: CacheManager: Creating a new instance of CacheManager using the diskStorePath "/usr/local/grouper/cache/api" which is already used by an existing CacheManager. The source of the configuration was URL of file:/usr/local/grou
per/grouper-api-1.3.1/conf/grouper.ehcache.xml. The diskStore path for this
CacheManager will be set to
/usr/local/grouper/cache/api/ehcache_auto_created_1222188550014. To avoid
this warning consider using the CacheManager factory methods to create a
singleton Cac
heManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance. Sep 23 19:49:10 localhost Grouper: INFO: EventLog: [deec941e-cde4-4ca0-847d-3dc2a7221e69,'GrouperSystem','application'] session: start (1489ms)

Grouper shell seems to work without problems.

Additional information: 469 # uname -a
Linux 2.6.9-78.0.1.ELsmp #1 SMP Tue Jul 22 18:11:48 EDT 2008 i686 i686 i386 GNU/Linux 470 # java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Server VM (build 10.0-b23, mixed mode)

Any ideas, what is going wrong?
