Tomcat 5.0.28 on Solaris 9 has been correctly serving Web apps
using both http and https. Then, after the Sun computer was
shut down and restarted, Tomcat failed to serve https requests.
It appears it could not initialize the https connector.
It continues to serve http requests normally.
Before the hardware shutdown, I had shut down and restarted
Tomcat and it continued to work normally. Breaking after a
hardware restart suggests that the problem is in the environment outside
Tomcat. Tomcat reports JAVA_HOME, CATALINA_HOME, and
CATALINA_BASE correctly. JSSE_HOME should not apply since I
have jre 1.4.1. What else influences https/TLS initialization?
The docs suggest some common failures, but I haven't found a cause
for this failure. I would appreciate pointers to what I need to learn
about this.
The symptoms: With an http address, Tomcat serves pages normally.
For an https address, Netscape 7.0 on Solaris 9 produces the alert
The connection was refused when attempting to contact <server>
while IE 6.0 on Windows Server 2003 produces the error page
This page cannot be displayed
Cannot find server or DNS error
Diff shows that server.xml has not changed since a time
when Tomcat was serving https correctly. The https connector in
server.xml:
<Connector
acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true"
keystorefile="conf/.keystore" keystorePass=<password>
port="443" scheme="https" secure="true" sslProtocol="TLS"
clientauth="false"
keypass=<password> keystore="conf/.keystore"
maxSpareThreads="75" maxThreads="150" minSpareThreads="25"
protocol="TLS" maxPostSize="0">
</Connector>
I suspect some of this is unneccessary, but I think that's a different
issue.
There's also an http connector, but it's working.
In catalina.out:
<date> org.apache.coyote.http11.Http11Protocol init
INFO: Initializing Coyote HPPT/1.1 on http-8080
<date> org.apache.catalina.startup.Catalina load

The code tells me CoyoteConnector failed to instantiate a protocol class.
I haven't convinced myself which class it's trying to use there.
Something on the system is occasionally writing backups of server.xml.
When that happens, the connector in server.xml has gained a second copy of
the attribute "secure". Then I have to edit server.xml so Tomcat
will parse the connector. Neither the system administrator nor
I have been able to discover what is doing that. I don't know if
that affects the main problem.
Thanks for insights.
