Ok, another question: will Tomcat 9 accept a "legacy" connector
definition in the form as shown below?
<Connector port="443"
protocol="org.apache.coyote.http11.Http11Protocol" maxThreads="150"
SSLEnabled="true" scheme="https" secure="true"
keystoreFile="/foo/tomcat/bar.ks" keyAlias="baz" clientAuth="false"
sslProtocol="TLS" />
To which Mark Thomas replied:
Yes.
This afternoon, I realized that I had a guinea pig available for testing
our webapp under Tomcat 9, on an IBM Midrange box.
With a connector defined according to the above form, I tried launching,
and got this:
06-Mar-2023 18:42:08.677 SEVERE [main]
org.apache.catalina.connector.Connector.<init> Protocol handler
instantiation failed java.lang.ClassNotFoundException:
org.apache.coyote.http11.Http11Protocol at
java.lang.Class.forNameImpl(Native Method) at
java.lang.Class.forName(Class.java:339) at
org.apache.coyote.ProtocolHandler.create(ProtocolHandler.java:260)
. . .
So I'm guessing I need to change the class given in the protocol
clause. To what?
Sorry, I didn't check the values provided in the example. I was just
looking at the overall style.
You need one of the following:
org.apache.coyote.http11.Http11NioProtocol
org.apache.coyote.http11.Http11Nio2Protocol
org.apache.coyote.http11.Http11AprProtocol
The significant change here is that HTTP BIO is no longer available in
Tomcat 9. Actually... HTTP BIO should not have been available to you in
Tomcat 8.5 either. Are you upgrading from 8.0.something?
These days, NIO is the default so unless you have a specific reason to
override that, I wouldn't even bother specifying the protocol.
