Hello!

Can you please answer is it possible to perform hot swap of view files (xhtml, css etc) with cargo maven plugin?

I am starting my java/jsf app on tomcat 7 with cargo maven plugin.

It runs great but when I change xhtml or css file in my working folders (not compiled one) there are no changes in the browser.

So is it possible to do so and I make some mistakes in pom.xml or it is not possible at all?

Thank you!

Hello :-)

It looks like you're trying to perform in place development, perhaps you can use the following sample for inspiration: https://github.com/codehaus-cargo/cargo/tree/master/extensions/maven2/samples/inPlaceDevelopment-test

Hi , Ali!

Sorry but can't quite understand how it works(

Should I just add this dependency to my pom.xml and I'll be able to modify my view files in working directories (src/java...) and changes will be immediately displayed in the browser?

<dependency>
  <groupId>org.codehaus.cargo</groupId>
  <artifactId>cargo-sample-maven2-inPlaceDevelopment-test</artifactId>
  <version>1.7.15</version>
  <type>war</type>
</dependency>

my full pom.xml and it doesn't work( no changes reflected in browser

Hello

I see - Actually, that is not a dependency, but rather an example, in other words you should use https://github.com/codehaus-cargo/cargo/blob/master/extensions/maven2/samples/inPlaceDevelopment-test/pom.xml for inspiration.

From what I see, the key is to use the <location>${expandedWebapp.directory}</location> in the <deployable> definition, so that what is deployed is the expanded WAR folder and hence your CSS and other modifications will (hopefully) be picked up by the container quickly.

On the other hand, having Java changes directly available in the container will be more complex: you need to somehow auto-compile things real time.

Hello

thank you, I think im starting getting it

But how it will detect changes in my view files?

Thanks

Hello

The location attribute is the directory to use when deploying the WAR, which implies that that directory is the one served by the container. There is no copying around.

Thanks

So to see changes in browser I'll have to change files that are in the container? or container somehow reacts to changes in working directories?

Sorry for stupid questions(

Kind regards

Hello

These are key questions :-)

To see the changes you'll need to ensure the files in the directory set as <location> are updated.

Does this help?

Hello

As I understood to see updates in browser I'll have to change files in expandedWeb directory(that will be in <location>)? and these are files from unpacked war?

or may I make something like to include html/css file's destination folder to <location>, but also I need my compiled java classes to be included to <location> attribute so it would also be in container.

so I need to specify 2 different locations in <deployable> smth like this

<deployable>

  <groupId>com.epam.training</groupId>
  <artifactId>myserv</artifactId>

  <type>war</type>
  <location>${project.build.directory}/classes</location>
  <location>${project.basedir}/src/main/webapp</location>
</deployable>

Thanks

kind regards

Hello

You are getting there - I'm unsure how your application is built, but that would be kind of what to do.

You can only have one <location>, though; so please check in your case where the files are getting generated and use that.
