Re: Building a uber/fat jar

[John D. Ament]

I use Maven for the actual build. I use these dependencies (with 9.0.0.M26):


org.apache.tomcat.embed
tomcat-embed-core


org.apache.tomcat.embed
tomcat-embed-el


org.apache.tomcat
tomcat-juli


org.apache.tomcat.embed
tomcat-embed-websocket


And use the Capsule Maven Plugin to build the actual runtime (better
isolation than a shaded JAR):


com.github.chrisdchristo
capsule-maven-plugin
${capsule.maven.plugin.version}



build


your.main.class.here
fat





And then the actual bootstrap would look like this:
https://paste.apache.org/vVNs (I put it in a paste since it's pretty long).

web-fragment.xml in embedded containers

Hi,

I was wondering if there was some configuration option that I could enable
in an embedded Tomcat container to have it process web-fragment.xml files?

So I wanted to make sure I didn't lose track of this.  Did you want me to
revise what I put out there, or were you going to bring in your changes?

If you want it, let me know.  I can provide a patch.  I'm not sure what
tests to add, other than verify no extra threads were created.  I need to
setup a bugzilla account too.

The problem is that tomcat is expecting a ThreadPoolExecutor.  It may make
sense to wrap it in a delegate that just handles the calls you need, since
you're only calling one method on the executor.  That would simplify this
logic as well.

Having an option to startStop on the main thread would fix my issue.
However would that be when startStopThreads = 1 or some other parameter (to
not break compatibility) ?

Populating init parameters

[John D. Ament]

Hi,

I'm using Tomcat embedded to start a container.  I need to set some
initParameters in that embedded runtime.  However, when I try to set the
parameters I get the follow:

java.lang.IllegalStateException: Initialization parameters cannot be set
after the context has been initialized

at
org.apache.catalina.core.ApplicationContext.setInitParameter(ApplicationContext.java:1003)
at
org.apache.catalina.core.ApplicationContextFacade.setInitParameter(ApplicationContextFacade.java:624)

I'm using the following to set the init parameter:

Context ctx = tomcat.addContext("",base.getAbsolutePath());
ServletContext servletContext = ctx.getServletContext();
servletContext.setInitParameter("key","value");

When i look, the tomcat instance is in the new state.  So it hasn't been
initialized yet.  I was wondering if this was an error?  I'm using Tomcat
8.5.9.
John

There's two ways to make this work.  The documentation you're reading is
referring to standard servlet containers.  E.g. someone's installed tomcat
somewhere and has a WAR with weld-servlet in it.

In my case, I'm using weld-se to bootstrap a JVM, wrote a CDI extension
that bootstraps Tomcat embedded, pointing to the embedded weld instance.
Its not designed for multiple apps, but a single service in that JVM.
Since I'm using an extension, weld isn't 100% started yet.  Since it hasn't
started yet, some of the bootstrap logic is trying to fire an event.  That
event shouldn't be fired quite yet, and its not able to coordinate that
between the threads, hence where I got this problem.

I ended up working around the issue by delaying Tomcat's bootstrap even
further, ensuring that the container is 100% up before trying to launch
tomcat.

I instantiate the Tomcat object and invoke start() on the "main" thread.
The invocation of ServletContextListeners happens on a
"localhost-startStop-1" thread.  I would like to have that invocation
happen on the main thread instead.

Its nothing within tomcat that is deadlocking, but under the covers weld
has a synchronized block, its inside that synchronized block where Tomcat
is instantiated.  There's a later point where Weld tries getting a lock
again.  In that case, when its single threaded (in other containers) it
passes since it has a lock, but in this case it can't get that lock.

So I was able to identify my issue.  It's not specifically a tomcat
problem, but tomcat's bootstrapping makes it unique.

one of the issues I've observed is that Tomcat's use of multithreading
causes some thread deadlocking with some synchronized blocks.  I was
wondering if there's a way to turn that off?  Make tomcat's bootstrap
happen in the same thread as the original invocation?

On a related note, documentation for tomcat embedded is scarce.  I usually
have to find it on non-apache channels.  What would be the best way to get
a document page started, maybe linked off of
http://tomcat.apache.org/tomcat-8.5-doc/index.html ?  What repo contains

Tomcat listener not coming up - no stuck threads

[John D. Ament]

Hi,

Looking for some external input.  I've put together a simple tomcat
embedded instance designed to deploy an arbitrary set of servlets, filters,
etc.

For some reason, when I run tests with Tomcat the server never fully
launches.  I can see the port in use, but connections to the server are not
answered by the instance.  When I debug the start up, I see what appears to
be a loop attempting to start services that never returns, in LifecycleBase.

Easiest way to reproduce it with this project is to clone
https://github.com/hammock-project/hammock/ and run a local build (to get
snapshots) and then run 'mvn clean install -Ptomcat-test' from
rest-resteasy (or spark or jersey).

I'm sure there's something simple I'm over looking.

Ah ha, perfect tip!  I can simply programmatically register default servlet
if none found.  And that works!

How to properly map a filter in tomcat embedded

[John D. Ament]

Hi,

I have this pretty straight forward case of starting an instance of tomcat
and bringing in a filter.

Tomcat tomcat = new Tomcat();
tomcat.setPort(8080);
File base = new File(".");
Context ctx = tomcat.addContext("", base.getAbsolutePath());
String filterName = "Default";
FilterDef filterDef = new FilterDef();
filterDef.setFilterName(filterName);
filterDef.setFilterClass(DefaultFilter.class.getName());
ctx.addFilterDef(filterDef);

FilterMap mapping = new FilterMap();
mapping.setFilterName(filterName);
mapping.addURLPattern("/*");
ctx.addFilterMap(mapping);
tomcat.start();
tomcat.getServer().await();
Thread.sleep(6);

My filter's pretty boring, but here it is

public class DefaultFilter implements Filter{
@Override
public void init(FilterConfig filterConfig) throws ServletException {

}

@Override
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse, FilterChain filterChain) throws IOException,
ServletException {
servletResponse.getWriter().println("Hello, world!");
}

@Override
public void destroy() {

}
}

When starting this up (Just running in a plain JUnit test), the container
is running however making requests to localhost:8080/ just result in
404's.  I'd expect my filter to handle those requests.

When using a servlet, its perfectly fine.

I tried it on both 8.5.4 and 8.0.30.

Any ideas?

Re: change persistence.xml at run time

[John D. Ament]

Well, Tomcat doesn't provide any support for JPA OOTB, so you'd probably
need to check w/ your JPA implementation on what they support.

When you say idle, is there an application deployed to tomcat, or is it
just the bare app server with nothing deployed?

Thanks for providing!

The attribute name on the user is roles not role

You should only define a user once and give them multiple roles.  Your file
should then look like this:

tomcat-users xmlns=http://tomcat.apache.org/xml;

  xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;

  user username=charnasol password=charnasol role=manager-gui /

  user username=tomcat1 password=tomcat1 role=manager-script /

  user username=tomcat password=tomcat role=admin-script,admin-gui /

 You should only define a user once and give them multiple roles.  Your

And also make sure you bounce tomcat after updating the tomcat-users.xml

 The manager-gui role isn't in the file you quoted below. It should be.
 Add it and then show us the new version of the file.

 Did you restart Tomcat after you edited tomcat-users.xml?

 If it still doesn't work, provide the full URL you are trying to access
 and the full text of any response you receive.

Re: JSR 236 with tomcat 8

[John D. Ament]

Concurrency utils is specific to app servers, where applications are
generally unable to create or manage threads.  This is an old EJB
limitation.

This limitation is not present in servlet containers.

Why do you think you need them?

Tomcat's a servlet container, not an app server.  If you want SOAP APIs,
you need to use a SOAP runtime like CXF in your app.

Re: Embedded Tomcat question

[John D. Ament]

Well, thanks for the helpful advice thus far..

So, now that I've added a listener properly, I get this:

java.lang.UnsupportedOperationException: Section 4.4 of the Servlet
3.0 specification does not permit this method to be called from a
ServletContextListener that was not defined in web.xml, a
web-fragment.xml file nor annotated with @WebListener

at 
org.apache.catalina.core.StandardContext$NoPluggabilityServletContext.addListener(StandardContext.java:7019)

When I try adding my listener...

@WebListener
public class CdiServletContextListener implements ServletContextListener
{
@Override
public void contextInitialized(ServletContextEvent servletContextEvent)
{
servletContextEvent.getServletContext().addListener(new
CdiCtrlListener());
}

I even tried rigging my class to have WebListener on it.. until I
noticed the method just threw an exception... no questions asked. :-)

 Given you are using 7.0.54, why would you look for a tag for 7.0.55?

 How do I get access to a StandardContext?  CAn I cast the Context object?

 Yes. It would have taken less time to try that than it did to type the
