Hi, I am trying to use oryx as an editor for my KB in RuleML. Being relatively new to oryx and mandarax, I was tying out the RuleML examples through the oryx interface. While trying to add new rules, I could not add new predicates. Is there som= e way by which I can create new predicates through the oryx interface for rules in RuleML? Priya |

Hi, after installing v3.7. On startup I get java.lang.NoClassDefFoundError: Illegal name: com/jbdietrich/oryx/gui/swing/plugin/joi/JOIPlugin$1. Sure enough all ..swing/plugin/*.class 's seem to be missing from the likely jars in the lib dir. cheers Colin. |

Dear Open Source developer I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate. You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it. With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development. With many thanks for your participation, Benno Luthiger PS: The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/. We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list. _______________________________________________________________________ Benno Luthiger Swiss Federal Institute of Technology Zurich 8092 Zurich Mail: benno.luthiger(at)id.ethz.ch _______________________________________________________________________ |

ClassCastException were thrown when i added a template rule to the repo=
sitory. The problem occured in CloneService.clone(Rule), line 53. The R=
ule's body is cast to Prerequisite, while the type is FactImpl (impleme=
ntation of Prerequisite's super class Fact).
This patch fixed the problem for me. It does not automatically handle n=
ew subclasses of Fact, this could be achieved by moving the clone()s to=
the Fact/Prerequisite classes.

< body.add(clone((Prerequisite) it.next()));

> final Object o =3D it.next();
> // Avoid ClassCast exception when saving templa=
tes in repository

> body.add(clone((Prerequisite) o));
> } else if (o instanceof Fact) {
> body.add(clone((Fact) o));
> } else {
> throw new RuntimeException("Unknown Fac=
t subclass " + o.getClass());
> }

Hi everybody.. I just wrote a tiny tool to create JPredicates from a class on-the-fly with some mouseclicks. Nothing very fancy but it might help when you want to create a lot of JPredicates base on a limited number of classes. The jar file (which also contains the source) is availble at http://www.teamskill.de/projects.html Just drop it in your Oryx plugin path and re-start Oryx. If somebody finds it useful: enjoy :-) -- Jens Fendler 2b|!2b==ff?UASW:null |

Hi all, * problem with Oryx3.6? Last night, I installed Oryx 3.6 using the new InstallAnywhere. Everything seems to be O.K. But at the end, InstallAnywhere displayed the following error message: "The installation of oryx is finished, but some errors occurred during the install. Please see the installation log for details." There was no installation log could be found anywhere. I ran the start.sh (after fixed the hard-coded paths described below) and it seems to be OK. * issuse with the paths of jars file in start.sh/start.bat: This is not new to Oryx3.6: the big problem that I am having is the start.sh/start.bat. The prebuilt version has "/home/jens/workspace/oryx/oryx-application/xxx" as the paths for the jar files. Unfortunately, I don't have directory path like "/home/jens/...." This happened because both start.sh/start.bat were created/modified during the build. The two variables in the original files of start.sh/start.bat will be replaced: @CLASSPATH@ @MAINCLASS@ The full path of classes will replaced the @CLASSPATH. Therefore, "/home/jens/..." were produced. If I rebuild Oryx from the source, I'll my own full path. I have to change them if I move the jars to somewhere else. Here is my propose: the current format is "/aaa/bbb/lib/xxx.jar". We could replace it with "./lib/xxx.jar" I believe the problem could be resolved. What do you think? Cheers, Chia |

I posted a bug at Oryx's web site earlier; however, the bug page seems to lack of activity. Therefore, I sent this email to communicate with you all. If there was any duplication, please forgive me. Tried to use the ORYX's CRM and Portfolio examples but it failed to create DB in PostgreSQL 7.4.x. The error message was: SQL FAILED: CREATE TABLE CUSTOMER_TRANSACTIONS (ID INT NOT NULL,CUSTOMER VARCHAR(20),AMOUNT DOUBLE,TRANSACTION_DATE DATE,PRIMARY KEY (ID)) The problem is the "DOUBLE" data type defined for AMOUNT. There are three files in the example directories I found that have the "DOUBLE" defined: 1. oryx/src/com/jbdietrich/oryx/examples/crm/CRMExample.java 2. oryx/src/com/jbdietrich/oryx/examples/portfolio_risk/PortfolioRiskExample.java 3. oryx/src/org/mandarax/examples/db/CreateDB.java According to PostgreSQL's doc, it accepts the "DOUBLE PRECISION" data type and not "DOUBLE". I also checked the specs of SQL 92 and 98 and they seem to use "DOUBLE PRECISION". After modified CRMExample.java and PortFolioRiskExample.java in oryx to use "DOUBLE PRECISION" and rebuilt oryx-3.5.4-application, I ran them successfully against PostgreSQL and MySQL. I didn't have the rest of databases on the list therefore I didn't try them. However, if they follow the SQL specs, I believe that it should work also. Maybe someone else has the other databases could give it a try. Thanks, Chia |
