I have Tomcat 7 + many webapps (webservices). All webapps needed search in LDAP directory. I configured Resource in conf/context.xml with any parameters and <resource-ref> in conf/web.xml.
In my webapps i have my LdapContextFactory class with com.sun.jndi.ldap.connect.pool definition.
Everything is ok, but ... when LDAP server is restarted, connection is lost and I don't now how configure automatic reconnecting (when possible, something like JDBC)
Thank's for help and sorry for my English

context.xml

<Resource name="ldap/LdapResource" auth="Container"

type="javax.naming.ldap.LdapContext"

factory="cz.XXX.ws.test.LdapContextFactory"

java.naming.security.authentication="simple"

java.naming.security.protocol="ssl"

java.naming.security.principal="cn=XXXXX, ou=AAAAA,o=BBBB"

java.naming.security.credentials="YYYYYYYY" />
