This is one technology that should help out right away. Type the correct command,
and you have a ready to run application. It basically does your homework for you.

It writes the code, creates the directory structure, and deploys the code.
The code templates are simple but you save a lot of time from creating directory structures
and tedious default headers, etc.
Here are some template or workspace types :

• Session/Entity EJB workspaces
• JDBC workspaces
• Web page creation
• Simple classes and interfaces

And I recommend using XDoclet, XDoclet this is not.

And this will not replace 'learning java' but I think it may be useful if you want to get started some example java projects with a 'single' command as opposed to do 100 google searches for code.

Note : This file contains a walkthrough of example operation for
SpiritCodeGen, typically download a java VM and just type 'runit',
I have included some walkthrough of DOS commands to show full
use of the system, don't get confused about what is a DOS command
and what is a SpiritCodeGen command, example 'dir'.

changes to  runit.bat :
  java -classpath "%LOCALCLASSPATH%" org.retro.gis.gen.CodeGen -help

..... INFO - WorkSet-Dir exists ... [ OK ]

usage: java org.retro.gis.gen.CodeGen <-h/-help>

    ..... <-listbuffers-xml>
    ..... [ List current code generation buffers in the config file ]


    ..... <-listbuffers-file>
    ..... [ List current code *.java buffer-files in 'output' dir ]

    ..... <-newproject [type] [new-name]>
    ..... [ Create one of a number of workspaces ]
    type : none ; entity-ejb ; session-ejb ; servlet ; jdbc


    ..... <-writebuffer [buffer-name] [new-name.extension] {-force}>
    ..... [ Write a buffer to file and replace tags from config file ]
    example-buffers : ZMakefileGen ; ZSimpleMainGen


    ..... <-writejava [buffer-name] [class/interface] [new-name.extension] {-force}>
    ..... [ Write a buffer to file and replace tags from config file ]
    example-buffers : YSimpleMainGen

 ex : org.retro.gis.gen.CodeGen -writejava class YSimpleMainGen ABC.java -force


* 2. Check what buffers the user can write to file, only use buffers starting
      with Z or Y.


java -classpath "%LOCALCLASSPATH%" org.retro.gis.gen.CodeGen -listbuffers-xml

..... INFO - Configfile exists ... [ OK ]

* 3. This command writes a simple buffer to the 'code' directory

java -classpath "%LOCALCLASSPATH%" org.retro.gis.gen.CodeGen 
          -writejava class YSimpleMainGen ABC.java -force

..... INFO - Configfile exists ... [ OK ]

* Wow, all these files get created, of course you need 'ANT to build the project *

... see build.xml to get an idea of the ANT tasks available.

Using the option '-newproject session.ejb', in the ejb-jar.xml file,
change the SomeProjectName.SomeProjectName to the package name used, for example
'org.retro.gis.system.SomeProjectName.

The linux scripts will not work very well because they were created in windows, to convert the script:
tr -d '(slash)015' < runit.sh > A mv A runit.sh chmod 755 runit.sh
