I've tried to re-install solr on tomcat, and now when I launch tomcat in
debug mode I see the following exception relating to solr. It's not enough
to understand the problem (and fix it), but I don't know where to look for
more (or what to do). Please help me.
Following the tutorial and discussion here, this is my context descriptor
(solr.xml):
<?xml version="1.0" encoding="utf-8"?>
<Context docBase="/Users/simpatico/SOLR_HOME/dist/solr.war" debug="0"
crossContext="true">
<Environment name="solr/home" type="java.lang.String"
value="/Users/simpatico/SOLR_HOME" override="true"/>
</Context>
(the war exists)
$ ls $SOLR_HOME/dist/solr.war
/Users/simpatico/SOLR_HOME//dist/solr.war
$ ls $SOLR_HOME/conf/solrconfig.xml
/Users/simpatico/SOLR_HOME//conf/solrconfig.xml
When Tomcat starts:
....

P.S. If the subject contains "[LON]" or the addressee acknowledges the
receipt within 48 hours then I don't resend the email.
subject(this) ∈ L(LON*) ∨ ∃x. (x ∈ MyInbox ∧ Acknowledges(x, this) ∧ time(x)
< Now + 48h) ⇒ ¬resend(I, this).
If an email is sent by a sender that is not a trusted contact or the email
does not contain a valid code then the email is not received. A valid code
starts with a hyphen and ends with "X".
∀x. x ∈ MyInbox ⇒ from(x) ∈ MySafeSenderList ∨ (∃y. y ∈ subject(x) ∧ y ∈
L(-[a-z]+[0-9]X)).
