How to build and debug OpenEMM by using Eclipse?

[aunthas]

Customizing OpenEMM for me is time consuming and so cumbersome. I have to build the whole project with Ant every time I want to test my single change. This gives me only final results without any clue of debugging information.

So I would like to ask for steps on building and debugging OpenEMM by using Eclipse. Or are there other ways to mitigate this unwieldy burden?

Just to make sure I understand you correctly: You need an archive file containing an OpenEMM release as Eclipse project (including files .project and .classpath) which you would like to import into Eclipse?

To use eclipse remote debugging you first need an OpenEMM eclipse project, but this is an easy job using the open sources. Once having your project you must run the httpd java process with jdb debugging options. to reach this just add the following text to your core.sh bash:

Code: Select all

 -J-Xdebug -J-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000 

Than in eclipse create a new Debug Configuration of type Remote Java Application. Use connection type standard (socket attach) and set your host and port correctly (8000). Finally click Apply and Debug. Now your eclipse debug process should connect to your httpd application, which is patiently awaiting this connect (suspend=y). Setting some breakpoints will quickly enable you to jump through the running app! Hope that helps

Code: Select all

export LANG=en_US.UTF-8
export RESIN_HOME=$HOME

echo ""
echo "+-------------------------------"
echo "|  $1 Resin httpd server..."
echo "+-------------------------------"
echo "$HOME/bin/httpd.sh -J-Xms128m -J-Xmx512m -J-Xdebug -J-Xrunjdwp:transport=dt_socket,server=y,suspend=n -conf $HOME/conf/core.conf -server-root $HOME/webapps/core -jvm-log $HOME/webapps/core/log/openemm_jvm.log -stderr $HOME/webapps/core/log/openemm_stderr.log -stdout $HOME/webapps/core/log/openemm_stdout.log -server core -pid $HOME/var/run/core.pid $args $*"

Hi,
i know this topic is a bit old. but is there a description how to get an usable eclipse version out of the source files?
i was creating a web project and was inserting the librarys in the buildpathes. but there are still some errors.
so whats missing? and my eclipse is stucking at validating "src\jsp\fckeditor-2.6.6\editor\_source"
is it even possible with windows? cause of the .sh files....

Did you read the Code Design Guide, section 2.1?

Did you read the Code Design Guide, section 2.1?

yes but there is nothing with windows or/and eclipse :S

If you want to edit OpenEMM's source code in Eclipse follow these steps:
- download and install Eclipse IDE for Java EE Developers
- create a new dynamic web project with source folders src/java + src/conf and content directory src/jsp
- unpack the OpenEMM source tarball
- import the unpacked files (and overwrite dummy files in dynamic web project)
- add all JARs from directory lib to the project's build path

Eclipse is available for both Linux and Windows.

i know but how do i set OpenEMM up in eclispe?
i would like to run it from eclipse

OpenEMM is definitely not the best project for you to learn about Java programming on. The community is relatively small, and contributions from it are rare (either in support or code - I don't believe there's even community SCM).

I am not new to Java and just want to know how to run it with eclipse. i cant understand whats so difficult to tell me how set it up.
just a simple explaination what kind of eclipse project, where to put the files in, which jars i neex (cause i still have some errors after adding the jars), how to setup tomcat,....
