Tomcat 8.5.x with Lucee

Martin_Schaible · January 3, 2017, 12:59pm

Hello

Instead of using Tomcat 8.0.x, i updated a server with Tomcat 8.5.x. My
fault
Before i start a downgrade, i like to ask, if tomcat 8.5.x is a kind of
supported for Lucee or not.

I discovered, that Tomcat uses a lot of memory (nearly 10GB) and i’m
wondering why.

Cheers

This is only anecdotal and not intended to take the place of a definitive
response regarding official support for Tomcat 8.5.x , but I am running
Lucee 5 on Tomcat 8.5.9 on one of my development servers without any
problems, and am not seeing anything odd in terms of Tomcat memory usage.On Tuesday, January 3, 2017 at 5:59:36 AM UTC-7, Martin Schaible wrote:

Hi,

I don’t think that Lucee “officially” supports any version of Tomcat as
such, more the servlet specification that the container engine is built to
support. I will see however if I can get some sort of “official” word on
this.

With regards specifically to Tomcat 8.5, it is the same servlet
specification version as 8.0, so should work exactly the same as 8.0:

http://tomcat.apache.org/whichversion.html

Kind regards,

Andrew

Lucee has never really kept a comprehensive list of supported servlet
containers and versions. Lucee should be guaranteed to run on the version
of Tomcat that our installers ship with, but I believe there’s also an
expectation that any other modern servlet container that follows the spec
should work as well, though we don’t put any effort out ATM to test all of
them. If you try running Lucee on a modern servlet container and it
doesn’t work, please put in a ticket. And perhaps someone can start a page
in our public wiki for people to catalog the servlet containers and
versions they’ve tested.

Thanks!

The servlet version required is specified in the source in the following
location:

github.com

lucee/Lucee/blob/master/core/pom.xml#L86


      
          <dependency>
            <groupId>org.apache.felix</groupId>
            <artifactId>org.apache.felix.framework</artifactId>
            <version>6.0.2</version><!-- 4.6.1 -->
            <scope>compile</scope>
          </dependency>
          <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
            <scope>compile</scope>
          </dependency>
          <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.2</version>
            <scope>compile</scope>
          </dependency>
          <dependency>
            <groupId>javax.el</groupId>
            <artifactId>javax.el-api</artifactId>

So currently Lucee requires a servlet container that supports version 3.1,
so Tomcat 8 and 8.5 fall into this category. As Brad has said there is no
specific testing of servlet container performed by LAS so no specific
container is recommended over another, as long as it follows the v3.1
specification then Lucee should in theory run on it without issue but that
is by no way guaranteed.

Kind regards,

Andrew
