Hello Ni Lin, you are right, the sources were accidentally encrypted with a password. Thanks for letting us know. I decrypted the sources and reuploaded the release. Please note, that d3web is also on github, it might be more convenient (and more up to date) to get the sources there: https://github.com/denkbares/d3web-Runtime Also you can check out our nightly distribution, which also brings a lot of improvements and fixes, and also the latest sources: https://repo.denkbares.com/list/downloads/distribution/d3web-KnowWE/nightly/d3web-KnowWE-distribution-12.0-SNAPSHOT.zip...

Hi Greg, this issue should be fixed with the new nightly-build, please try again. https://www.d3web.de/Wiki.jsp?page=Downloads Regards Albrecht

Hi Greg, thanks for reporting! At first sight, this looks like a bug in the Image-Map plugin. I will try to have a closer look in the next days, will let you know when it is fixed (will be the nightly-build then). Regards Albrecht

Hmm, I still suspect your JDK, because that compiler error is pretty typical for it. Just to be sure: Is there a tools.jar at /usr/lib/jvm/java-8-openjdk-amd64/lib? Thats what needed for the OntologyCompiler. If its not there, something is not right with your path/JDK installation. Also, could you check the logs of tomcat and paste the trace for the message "Unexpected internal exception while compiling with OntologyCompiler (Demo - Simpsons): null" here? That would help too. Regards

Hi, what does your JAVA_HOME variable look like? It should point to your JDK. Your error 1 should be a symptom of using JRE instead of JDK. Error 2 is probably a follow-up error to error 1. Regards Albrecht

If you want to use a variable in one of your formulas or any other knowledge snipplet in KnowWE, e.g. rule or flow chart, you have to define that variable in the %%Question markup, there is currently not really a way around it. I'm not sure if you understood correctly how to set values though. You don't set the values in the question markup, but afterwards either in any of the interviews like %%QuickInterview, or via tha API as described here https://www.d3web.de/Wiki.jsp?page=How-To%20Create%20a%20Session#section-How-To+Create+a+Session-EnteringFactsToTheSession...

Hey Yang, yes, you can do this using the TimeDB-Plugin and abstract questions. Example: You have a pressure sensor and a variable threshold (maybe depending on temperature), at which you want to classify the pressure as ok or to high. It would look something like this: %%Question pressure [num] pressure_threshold [num] <abstract> % %%Solution Pressure to high % %%Rule IF eval(pressure > pressure_threshold) THEN Pressure to high = P7 % You can set the threshold the same way you set the value for other...

Hey Yang, I guess this question is also refering to your modelling with multiple equal components in your larger system. As I already described there, this concept does not really exist in d3web in this way. It is possible to do loobs using Javascript-Functions (see here: https://www.d3web.de/Wiki.jsp?page=Doc%20Javascript%20Functions) but I guess this is not what you need. Regards Albrecht
