Hi all
I have been trying to deploy a custom actor[which extends TypedAtomicActor]
that I have created using the kepler development environment. The actor
works if i instantiate kepler from my devpt. environment. now I need to take
the source files, class files, .xml, .MF files and place it in kepler
version alpha 9.0 and try to bring up the actor in my ontology tree, WITHOUT
COMPILING OR BUILDING. I am using windows XP OS.
For the past two weeks I did some kind of study and found a write up that
might help me in my endeavour.
http://mercury.nceas.ucsb.edu/ecoinformatics/pipermail/kepler-users/2005-May/000006.html
accordingly,
1. I tried to modify Kepler_alpha9.lax with 'src/fpkg' added at the end of
classpath, where fpkg is the package containing the source and class files
for my actor.
2. then I modified the annotation.owl file with the following script
<!-- "File Chooser Actor" "urn:lsid:localhost:actor:473:1" -->
<asc:Annotation rdf:ID="A419.1">
<asc:lsid>urn:lsid:localhost:fpkg:A419:1</asc:lsid>
<asc:annotates>
<asc:ItemTag>
<rdf:type rdf:resource="&ont;FileSystemActor"/>
<asc:taggedItem>
<asc:Actor>
<asc:lsid>urn:lsid:localhost:actor:473:1</asc:lsid>
</asc:Actor>
</asc:taggedItem>
</asc:ItemTag>
</asc:annotates>
</asc:Annotation>
The intention is to place my actor whose LSID is 473 under FileSystemActor
group.
3.In keplerActorOntology.owl file, I added the following at the end
<owl:Class rdf:about="urn:lsid:localhost:onto:1:1#FileChooserActor">
<rdfs:subClassOf>
<owl:Class rdf:about="urn:lsid:localhost:onto:1:1#FileSystemActor"/>
</rdfs:subClassOf>
<rdfs:label rdf:datatype="http://www.w3.org/2001/XMLSchema#string"
>File Actor</rdfs:label>
</owl:Class>
4.I had the .java files and the .class files in a folder called fpkg, which
I copied it in kepler-1.0.0alpha9/src folder
and under the kepler-1.0.0alpha9/src/actor folder, I created a folder called
FileChooserActor within which I copied the xml and MF files for the actor. I
have also attached the xml as well as MF files for your reference. Matt's
suggestion of placing the class files in org.kepler.* also gave me the same
error of 'classpath not found' (see err3.bmp).
5.In C:\kepler-1.0.0alpha9\build\kepler.jar, I manually added the .class
files from C:\kepler-1.0.0alpha9\src\fpkg\* .class which I added in step 4.
The processof manual addition is to open the kepler.jar file using winzip
and then using 'add' command to add the class files from src/fpkg location ,
checking the 'use full path' checkbox.
6. I then used cygwin withnthe command "ant buldkarlib" for building the kar
library. It was successful.
7. Then I double clicked the kepler_alpha9 launchAnywhere zerog software
icon to get kepler running.
I am getting the classpath not found error for the umpteenth time even
though I found the src/fpkg folder added to the classpath. The error message
is given in err.bmp file, with the classpath added using the lax file
underlined in orange.
questions:
1. What are the general steps to be undertaken to deploy custom actors in an
existing kepler version? obviously the above steps are not sufficient.
2. In keplerDevelopment tutorial you have a tutorial to build your own
kepler actor 'Helloworld' using the deveopment environment. But what about
its deployment in a kepler version say alpha9.0?
3. I need to submit my custom actors and workflows to my project manager and
also install them in his machine. How do I do it?
4. My reason for not building C:\kepler-1.0.0alpha9\:
I installed a fresh version of kepler alpha 9.0, and used 'ant run-dev'to
compile and build.
it requires ptolemy i.e. the environment variable PTII indicating the
ptolemy source files. I cannot expect my manager to have the ptolemy source
files in his machine! nevertheless I used my PTII directory and proceeded.
It gave errors like some keplersplash.png and log file missing. I copied
those files from my development environment and placed it in the alpha 9.0
version. Here again my manager being a user, would have no idea about these
errors.
it gave me the following error:
"compile-dev:
[javac] Compiling 878 source files to
C:\kepler-1.0.0alpha9\build\classes
[javac] C:\kepler-1.0.0alpha9\build\src\ptolemy\actor\Director.java:119:
pto
lemy.actor.Director is not abstract and does not override abstract method
isStri
ct() in ptolemy.actor.Executable
[javac] public class Director extends Attribute implements Executable {
[javac] ^
[javac] Note: Some input files use or override a deprecated API.
[javac] Note: Recompile with -deprecation for details.
[javac] 1 error"
so I decided that the deployment should be without building or compiling
kepler alpha9.0. I can use buildkarlib for creating the kar files though.
5. How to deploy the custom actor in kepler version alpha 9.0? can somebody
try deploying the Helloworld actor in kepleralpha9.0 and let me know the
steps atleast?
Thanx
Siva
