Re: Which maven provided dependencies to target Tomcat ?

[Xavier Dupont]

Hi Luis,

I'm sorry to say that if you use javaee-web-api on Tomcat, you will pull,
among others, javax.transaction:javax.transaction-api:1.2 which contains,
for example, javax.transaction.HeuristicCommitException and if you try to
put resp.getWriter.println(HeuristicCommitException.class.getName()); your
IDE won't complain but the servlet will throw a ClassNotFound exception at
runtime.

This assuming javax.transaction.HeuristicCommitException is not brought by
some other dependency.

You will get the same result with many other dependencies of javaee-web-api.

I actually performed the same experience with all 17 dependencies of
javaee-web-api, selecting one arbitrary class and checking if it was found
when deployed on tomcat, and I found that only the following should be
included in a project which targets tomcat 8.5 / Java EE 7


javax.el
javax.el-api
3.0.0
provided


javax.servlet
javax.servlet-api
3.1.0
provided


javax.servlet.jsp
javax.servlet.jsp-api
2.3.1
provided


javax.websocket
javax.websocket-api

javax.annotation

You may want to use Apache TomEE instead of Tomcat. TomEE uses Tomcat
at the code, but already provides the remaining "web profile"
dependencies.

Hello Xavier,

Perhaps you can have a look here:
https://wiki.apache.org/tomcat/Specifications.

Me, I have:


javax
javaee-web-api
7.0
provided


Hope it helps,

Luis

Which maven provided dependencies to target Tomcat ?

[Xavier Dupont]

Hi guys.

If I want to target the Java EE full profile, I use go here
https://mvnrepository.com/artifact/javax/javaee-api/8.0 and get the
following XML snippet.


javax
javaee-api
8.0
provided


If I want to target the Java EE web profile, I use  this url instead
https://mvnrepository.com/artifact/javax/javaee-web-api/8.0

And if I only need a subset of JSRs included in the javaee web profile,
they are all nicely included in the list of compile dependencies, this is
all very nice.

Since tomcat only supports a subset of the web profile, which dependencies
should be added in maven ?

Here's the full list for the Java EE 7 Web profile.

javax.annotation:javax.annotation-api:1.2
javax.ejb:javax.ejb-api:3.2
javax.el:javax.el-api:3.0.0
javax.enterprise:cdi-api:1.1
javax.faces:javax.faces-api:2.2
javax.inject:javax.inject:1
javax.interceptor:javax.interceptor-api:1.2
javax.json:javax.json-api:1.0
javax.servlet:javax.servlet-api:3.1.0
javax.servlet.jsp:javax.servlet.jsp-api:2.3.1
javax.servlet.jsp.jstl:javax.servlet.jsp.jstl-api:1.2.1
javax.transaction:javax.transaction-api:1.2
javax.validation:validation-api:1.1.0.Final
javax.websocket:javax.websocket-api:1.0
javax.ws.rs:javax.ws.rs-api:2.0
org.eclipse.persistence:javax.persistence:2.1.0
org.glassfish:javax.faces:2.2.0

I ask because I couldn't find the answer on the web, and it seems to me
that many sources are actually quite wrong and how it should be done.
I believe this should appear in a section of the tomcat documentation, at
least for versions 6, 7, and 8 of Java EE, which Tomcat seems to track.

Xavier.
