General Formatting Conventions

The OFBiz project follows the Sun coding standards for Java source code. For information regarding this standard please visit http://java.sun.com/docs/codeconv/html/CodeConvTOC.doc.html

The line length of 150 is an exception to the Sun standard

Here is an example of a Java formatter for Eclipse

For Groovy we suggest you read http://www.groovy-lang.org/style-guide.html but we don't expect people to follow all details there, still a good read..

HTML code should be XHTML compliant. Groovy and Javascript files should follow the same conventions as Java files.

...

1. Java -> Code Style -> Code Formatter -> Show... In dropdown pick -> Java Conventions built-in -> Indentation, select Tab policy as "Spaces Only". Enter a new name for this profile and click "OK".
2. Java -> Editor -> Typing, and check "Insert spaces for tab".
3. General -> Editors -> Text Editors -> Insert spaces for tabs
4. Ant -> Editor -> Formatter, and uncheck "Use tab character instead of spaces".
5. If you installed Colorer, Colorer Library Editor -> Uses spaces instead of tabs.
6. If you installed XML Buddy, XMLBuddy -> Formatting -> Uses spaces instead of tabs.
7. If you installed Oxygen, Oxygen -> Editor -> Format -> uncheck Indent with tabs, indent size 2 (beware for existing files with 4 spaces, always a trouble :/)
8. XML -> XML Files -> Editors -> Text Editors -> Indent using spaces (4)
9. Unfortunately the main FreeMarker plugins has no Unfortunaltely neither of the 2 main FreeMarker plugins have similar functionnality yet. But there is somehow a (sometimes annoying) solution :
   • Install AnyEdit plugin (http://andrei.gmxhome.de/eclipse/) and set its parameters in General -> Editors -> AnyEdit Tools. When using AnyEdit plugin, you should set it to
     • Convert tab to space (it's by default in last versions)
     • Add filters (like *.js, *.css) for files you don't want to auto-convert)

In Eclipse, for Java, you may use Ctrl+I to be sure of correct indentation.

For Javascript in Eclipse we suggest to use Aptana and to import /tools/ofbiz.aptana.js.format.xml (from Windows/Preferences/Aptana/Editors/Javascript/Formatting/Import in Eclipse).

Files paths

• Java
  The OFBiz project follows the Maven Standard Directory Layout to organise its Java files. At the moment of writing there are only a few unit tests (but a lot of what we so far call integration tests) so you will mostly find the ../src/main/java/org/apache/ofbiz.. path in components. As of today in few components in framework (base, entity, start, webapp) you will also find the ..src/test/java/org/apache/ofbiz.. path
• Groovy
  We decided to use a groovyScripts sub-folder under components folders to put parsed Groovy scripts. We named it groovyScripts rather than script because other script languages could be used in the future
  Even if it's no used yet we reserved the groovy sub-folder under components folders for pre-compiled Groovy scripts. A distant goal is to replace Minilang by a Groovy DSL...
• Freemarker
  The Freemarker templates are in template sub-folders under components folders
• Minilang
  The Minilang map processors and minilang scripts are in minilang sub-folders under components folders

Misc.

In OFBiz we don't set serialVersionUID but let the system handles that for us and rather use @SuppressWarnings("serial") where necessary.

License Headers

Each and every source file should contain the ASL2.0 header:

...

In most of case, the request name is the same than the view-map called. For the request-map name use java naming convention for Objects (ex : "FindParty"), and declare all in one line.

     <request-map uri="FindParty"><security https="true" auth="true"/><response name="success" type="view" value="FindParty"/></request-map>

...

For the request-map name use java naming convention for field or method (ex : "editParty"), and declare each xml element on separate line

   <request-map uri="createPerson">
        <security https="true" auth="true"/>
        <event type="service" invoke="createPerson"/>
        <response name="success" type="view" value="EditPerson"/>
        <response name="error" type="view" value="EditPerson"/>
    </request-map>

...

For the view-map name use java naming convention for Objects (ex : "FindParty"), and declare all in one line.

    <view-map name="FindParty" type="screen" page="component://mycomponent/widget/PartyScreens.xml#FindParty"/>
