OpenSpaces.org is alive — project creator will move there soon
December 11th, 2007GigaSpaces has started work on OpenSpaces.org and associated with the pending launch of the site is a call to arms for all who hack.
Check out: Open Spaces Developer Challenge I think there is even a sizable prize involved!
As soon as I can, I will make project creator available on OpenSpaces.org so anyone who wants to can improve it -extend it etc…
Cheers,
Owen.
SBA –all over the world!
October 22nd, 2007Wow!
This Fellow seems to really like GigaSpaces and SBA!!
Check out his blog here.
I wonder where he got his material for the blog…?
I guess the influence of SBA on the architect is felt worldwide.
: )
It does my heart proud to see more and more the path of the parallel and co-located rising up to meet the feet of the technologists who seek it.

DemoKit — here are the files I used when recording the last version of the projectcreator screencast
September 11th, 2007If you want to look carefully through the templates and scripts I used for the screencast demo, you can download them in a jar file (it is really a zip) from here

Project Creator Version .03
September 11th, 2007(My good friend Toby Found a BUG (NPE) I have since fixed it and added one more trick)
You may download the latest jar from any of the links referring to it.
Such as this one here
(I only have the latest copy available and all links point to the same one)
Note the src.jar is similarly updated and can be found here
Added features:
For those of you who want to add additional files and get really fancy - and in anticipation of supporting Spring Remoting with at least one specified Interface and a possible DAO etc… I have added the ability to do two more things with project creator. (these will no doubt again be improved upon, but for now they suffice to allow me to extend the available use-cases this tool will support)
The Two Added Features:
- First Feature: (Pretty Cool and useable)
Specify the existence of a properties file called customTokens.properties and specify its directory. You specify the flag and also the relative or absolute directory containing customTokens.properties fileexample:
The contents of that properties file is a series of named tokens and their replacement values.
-customTokens ./extraStuffGoesHere
example:
-customTokens c:/tmp/wrk/extraStuffGoesHere
NB: The tokens must all begin with @
example:
# the use of this file allows you to add arbitrary name-value pairs which will
# act as replacement tokens within the massaged (template) files.
# the massaged (template) files are limited to:
# whatever you provide as args to :
# -setServiceTemplateName
# -setPUTemplateName
# -customTemplateFileNameList (comma-separated list of files found in the -templateDir)
# as well as the always generated:
# build.xml
# the sometimes generated:
# dataObject.javasrc
# and the various files generated by the intellij and eclipse handlers
#to avoid name conflicts it is advised to use a prefix such as @username.THETOKEN
# Where username is the prefix and token is the thing you care about
# note that in your template files you will have to provide the complete matching token
@owen.description=/* A really wild ride baby! */
@owen.methodsig= public static void doIt(){
@owen.attribute1=someContent
@owen.property1=SomeContent
- Second Feature: (Kinda ugly and less than simple to get correct)
Specify the existence of additional files to be used as templates (The astute will notice this was hinted at in the comments within the example customTokens.properties file above)
It is important to note that there are several expected conditions within the project creator to enable this to work:
- You must specify the flag -customTemplateFileNameList followed by a comma-delimited string containing the filenames of the extra template files you wish to include
example:
-customTemplateFileNameList Message.javasrc_custom,readme.txt
- If adding additional java source files as templates: You must also specify the flag -customPackageDir and supply a single valid package into which they will *all* be placed
example:
-customPackageDir com.test.common.interfaces
- The package declaration of each of the additional java source templates should also contain this value as either hard-coded or using the following expected token: @customPackageDir
- The filename given to the java source template must contain the string: “javasrc” somewhere
example:
-customTemplateFileNameList ServiceInterface.myjavasrc_secondVersion
- The Resulting java Class or interface will be created using the first-half of the given template filename
example:
ServiceInterface.myjavasrc_secondVersion becomes ServiceInterface.java
- As a result of the above, the Class or Interface name specified within the java template must match the first-half of the given template filename
example:
public interface ServiceInterface extends Serializable{
- Non-Java Files specified as part of -customTemplateFileNameList will be saved into the project root directory and will be given the exact same name as provided template filename
example:
readme.txt becomes readme.txt and is placed in the root directory of the project
Again, the primary reason for adding such additional functionality is for me to be able to offer additional templates and examples of such things as Spring Remoting using OpenSpaces and the use of DAO decoupling - not to mention adding additional monitoring services and their associated datatypes that will store their discovered values using the space.
If you find this additional (restrained) flexibility useful for your purposes as well –great! But feel free to ignore it as well.Finally, an example of a script that uses all the above-described features:
(latest args made available in this release are in bold)

Example Script: createCustomStuff.cmd

version .02 Update to project-creator.jar –Make your own templates!
September 7th, 2007I have made another fix to the project-creator.jar found here.
This fix allows you to specify
-templateDir X
where
X = path relative to the directory from which the script is invoked
or
X = Absolute pathexample:
Let’s say I want to create a new template for my data Object so that it always has a defined String property.
I create a file called “dataObject.javasrc” (because that is currently the only name available for the dataObject template file)
The file could look like this:
***package @packageName.common;
public class @dataObjectName {
private String dummyValue;
public void setDummyValue(String val){dummyValue=val;}
public String getDummyValue(){return dummyValue};
}***
I save that file in:
c:\tmp\openspaces\mytemplatesin c:\tmp\openspaces I have a script that looks like this: (changes from previous examples are in different font)
****
rem Personal Settings (these change according to each machine environment)
set JAR_FILE_LOCATION=./project-creator.jar
set OUTPUT_DIRECTORY=c:/tmp/openspaces/output
set JAVA_HOME=c:\java\jdk1.5.0_07
if “%JSHOMEDIR%.” == “.” set JSHOMEDIR=c:\GigaSpacesXAP6.0rem Script-specific Configuration Settings:
set PROJECT_NAME=Worker
if “%IDE%.” == “.” set IDE=-eclipse
set SERVICE_TEMPLATE_NAME=service.javasrc_myversion
set PU_TEMPLATE_NAME=pu.xmlsrcset TEMPLATE_DIR=-templateDir ./mytemplates
rem General Options
rem elect to overwrite existing projects with same name:
set OVERWRITE_OPTION=-overwritecall %JAVA_HOME%\bin\java -jar %JAR_FILE_LOCATION% %IDE% %OVERWRITE_OPTION% -project %PROJECT_NAME% -out %OUTPUT_DIRECTORY% -setServiceTemplateName %SERVICE_TEMPLATE_NAME% -setPUTemplateName %PU_TEMPLATE_NAME% -gigaHome %JSHOMEDIR% %TEMPLATE_DIR%
****
If I call that script from the c:\tmp\openspaces directory all will be well and it will find my new version of the dataObject.javasrc file.
If I do not want to call it from that dir everytime, I can instead provide the arg:
set TEMPLATE_DIR=-templateDir c:/tmp/openspaces/mytemplates
and call the script from anywhere.If the template needed for an operation is not provided in your specified TEMPLATE_DIR, projectcreator will look for it in the jar file as usual.
The template directory structure is as follows:
/%templateDir%
/%templateDir%/eclipse
/%templateDir%/intellijAll the templates are stored in the root of the templateDir except the files used for eclipse and intellij.
Some of the templates you can create must have certain names such as:
build.xml
any of the eclipse or intellij files
dataObject.javasrcThe template files used for the Service.java and pu.xml files can be given any name you like.
Within the templates you create you can currently use any of the following as replacement tokens: (consult the source code found here for more details)
@projectName (Name of the project you want to build)
@spaceName (Name of the space you want to connect to ex: MySpace)
@propertySpaceName (Name of the space with a lowercased first letter – derived from @spaceName ex: mySpace)
@varGSHome (Path to [and including] Root Directory of your XAP installation)
@spaceUrl (This is derived from the @spaceName and your choice of remote or embedded)
@packageName (You specify this as the package for your first service in this Project)
@packageDir (This is derived from the @packageName)
@serviceName (You specify this as the name of your service class)
@dataObjectName (You specify this as the name of your data class (note the package name will set to @packageName.common to ensure this class is packaged in a separate jar file for classloading purposes)I hope this addition makes this utility even more fun to use.
Cheers,
Owen.
