Question

Doc needed on where the compiled class files be stored for new japidroot approach

R. Rajesh Jeba Anbiah commented 11 years ago

With the new japidroot approach, the compiled template class files are not created within app path when we create WAR. And so, it doesn't work in Tomcat. Any documentation on this might be helpful.

Its a neglect on my part . Haven't considered the use with tomcat. What's your way of generating the war file?

If I understand your question right, we create WAR in the following approach in Windows:

play war appfolder -o appname
jar -cvf ROOT.war

Not sure, if the below stack trace will give you any idea:

created: japidroot/japidviews/_javatags
created: japidroot/japidviews/_layouts
created: japidroot/japidviews/_tags

The class files are never output to file system in the post-controller integration mode. The "separated" mode assumes a folder named "japidroot" in the working directory. The "current working directory" in a jee server is not defined and may be located in a place you never would imaging.

The Japid42 project contains a short description of using it in a servlet environment. Search "Use Japid in any Java applications" in https://github.com/branaway/japid42.

The standalone mode of Japid42 should work for any Java apps including Play1. See if would fit your need before I enhance Japid for servlet containers.

R. Rajesh Jeba Anbiah · Answer 4 · Thu Aug 01 2013 19:40:27 GMT+0800 (China Standard Time)

Thanks a lot for a quick reply. Will check "Use Japid in any Java applications" now.

Bing Ran/冉兵 · Answer 5 · Fri Aug 02 2013 17:25:22 GMT+0800 (China Standard Time)

I have found out the layout used by the "play war" command. What you can try is create a serlet to bootstrap Japid and configure the root path, something like:

public class S2 extends HttpServlet {

public void init(ServletConfig config) throws ServletException {
        String p = config.getServletContext().getRealPath("WEB-INF/application/japidroot");
        JapidPlayRenderer.setTemplateRoot(p)
}

}

Bing Ran/冉兵 · Answer 6 · Fri Aug 02 2013 17:26:15 GMT+0800 (China Standard Time)

BTW, I have made some changes in Japid hopefully that would work out of box when running in Tomcat. Can you grad the latest jars from: https://github.com/branaway/Japid/tree/master/lib ?

R. Rajesh Jeba Anbiah · Answer 7 · Fri Aug 02 2013 19:29:58 GMT+0800 (China Standard Time)

Thanks, very kind of you. We thought of degrading the version, but will check this version and let you know. Thanks again.

R. Rajesh Jeba Anbiah · Answer 8 · Fri Aug 02 2013 20:31:07 GMT+0800 (China Standard Time)

We tried the new jar, but getting below error.

System error 500: play.exceptions.JavaExecutionException: Japid template class not found: japidviews.Users_Controller.home

Since, there's some urgency, we have decided to downgrade our japid version now (Though standalone version may work, we thought it may demand more time/changes.). After that we'll closely try this with other options and update.

Many thanks for your great support.

Bing Ran/冉兵 · Answer 9 · Fri Aug 02 2013 21:07:43 GMT+0800 (China Standard Time)

Sorry to hear that. When you have time, can you make a minimal application
that demos the problem?

I have identified one bug with Japid and one defect with Play that prevents standalone Japid mode with Tomcat. Can you try 0.9.23 and see if it has dealt with them.

Bing Ran/冉兵 · Answer 12 · Sat Aug 03 2013 16:41:15 GMT+0800 (China Standard Time)

this is a sample dependencies.yml file to reference them:

require:

    - cn.bran -> japidplay 0.9.23
    - org.eclipse.tycho -> org.eclipse.jdt.core 3.8.2.v20120814-155456

For a quick check, we tested with JapidContact2 application. We get same error as shown below. Note that we haven't yet checked the standalone version, as we're more inclined towards japid play version due to its invoke and content negotiation features.

I got the same error with an older version of Japid because of the way it
dealt with path containing dot. I have fixed that. And I have my sample app
deployed on tomcat and its working. Can you try the latest jars in the
Japid project, in the lib dir?

I have updated the JapidContact2 sample app to refer to Japid 0.9.25. It worked OK with my local Tomcat 7.

I wonder it would work in your environment.

1 Clone the latest Japid from github.
2 cd JapidContact2
3 play deps --sync
4 play run

To deploy to Tomcat:

play war JapidContact2 -o jc2
copy the jc2 folder to tomcat webapps
start tomcat
browse to http://localhost:8080/jc2

Bing, I can confirm that we didn't use the latest jar. But, we're yet to check the latest jar. Since, we're working for the release, it's taking time. Sorry for that. I hope latest jar should work as you have already checked. We'll check as soon as we're set. Thanks again.
