Just start the server: ./ape.exe -httpserver and then call from your application, e.g. <a href="http://localhost:8000/?text=Every+man+is+a+human.&solo=drsxml" rel="noreferrer" target="_blank">http://localhost:8000/?text=Every+man+is+a+human.&solo=drsxml</a></blockquote><div> <div class="gmail_default" style="font-size:small">Ok, I think it's a good solution. the only concern is the fact that in our platform (Amine), things must not be complicated for users, which are often not computer scientists, so they would not have to run any external program. If the APE HTTP server start/stop operations can be performed programmatically, it would be perfect, the platform runs the server before the analysis of the ACE text, and stop it once the DRS is generated. What do you think ? and if the command line ape.exe -httpserver runs the server, how to stop it ? </div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> and parse the result. Actually the Java Interface for APE does the parsing for you, see the Javadoc <a href="http://attempto.ifi.uzh.ch/site/docs/java/apidocs/index.html" rel="noreferrer" target="_blank">http://attempto.ifi.uzh.ch/site/docs/java/apidocs/index.html</a> and a concrete example how to use the webservice: <a href="https://github.com/Attempto/APE/blob/master/java/src/test/java/ch/uzh/ifi/attempto/ape/APEWebserviceTest.java" rel="noreferrer" target="_blank">https://github.com/Attempto/APE/blob/master/java/src/test/java/ch/uzh/ifi/attempto/ape/APEWebserviceTest.java</a> i.e. you just need to start the server and have attempto-ape.jar on your classpath to be able to use it via simple Java methods. </blockquote><div> <div class="gmail_default" style="font-size:small;color:rgb(0,0,0);display:inline">It's perfect. </div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> I agree, getting the JPL-based access (i.e. APELocal) to work is complicated. That's one of the reasons I prefer the HTTP-interface. Your error (NoClassDefFoundError) indicates that JPL is not found on the Java class path. Have you tried the instructions on <a href="https://github.com/Attempto/APE/tree/master/java" rel="noreferrer" target="_blank">https://github.com/Attempto/APE/tree/master/java</a>? I just tried, and all the tests worked (mvn test). I had to make the following modification: <a href="https://github.com/Attempto/APE/commit/b1eab4e0640ab09fecdeb69ccccb8473dd4af947" rel="noreferrer" target="_blank">https://github.com/Attempto/APE/commit/b1eab4e0640ab09fecdeb69ccccb8473dd4af947</a> </blockquote><div> <div class="gmail_default" style="font-size:small;color:rgb(0,0,0)">I made the modifications, but I have probably a jar versionning problem, the version of my jpl is 7 (because I have SWI-Prolog 7.3.16), which is, I suppose, not compatible with the attempto-ape.jar.</div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> You probably need to do something similar. (We don't currently have a more general solution, that would work out of the box.) I'd prefer to continue this discussion on the mailing list, in this way other users can profit from it as well. </blockquote><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> Best, Kaarel On Sun, Jan 31, 2016 at 11:33 PM, Mohammed Nasri <<a href="mailto:mohammed.nasri@gmail.com" target="_blank">mohammed.nasri@gmail.com</a>> wrote: > Hi Kaarel, > > Thank you for you answers and your suggestions. > > For information, here is the exact command line I generate : > /Users/mohammednasri/Travail/TLN/tln/tools/APE/ape.exe -text "John eats an > apple." -solo drsxml > > When I copy/paste this line and run it in the terminal, it seems to be > correct, but with the java application, I get the following error : > ERROR: Illegal argument: arglist_namevaluelist/2: eats > > Otherwise, I cannot use the APE HTTP interface if it requires an internet > connection. > > I suppose, on the other hand, that the Java bridge is the best solution, if > it calls the locat APE instance.
