Re: [topbraid-users] Re: Query in Sparql View versus UpdateQuery in sm Script

[Scott Henninger]

John;  In terms of passing a string argument, the best way to do this is to use one of the wizards to set the type in the spl:Argument's to be what you want it to be in the end.  If that's a string, then use xsd:string.  If it's a URI, then set to rdf:Property, owl:Ontology, owl:Class, myns:Thing_1, etc and it will be cast the value, if it is a properly formatted URI. In that respect, make sure you use the Scripts > Create SPARQLMotion function/web service...  This wizard does three things:   1) creates a new script   2) names the script so it can be called as a Web service   3) creates the arguments using the spl:Argument template wizard In terms of the Web service call, everything starts out as a string.  And you do have to be careful about getting the proper HTTP encoding.  The exceptions you sent indicate that perhaps the URI that was passed was not well-formatted.  One hint is that most entities (browsers, etc.) will take slashes but not hashes, so use %23 for '#'. Finally, I attached a script that has an example of passing a value that is cast to a property and used to query our favorite kennedys model.  Test it with the URL:   http://localhost:8083/tbl/sparqlmotion?id=http://support.tq.com/exampleServicePassArgument%23GetKennedyPropValues&property=http://topbraid.org/examples/kennedys%23name Hopefully that can give you solid ground to start from. -- Scott On 3/11/2013 7:31 PM, John Perdoni wrote: Scott I am now getting the following error, I shall delete the script and start again, I agree with you that nothing is wrong on the surface, but any advice on how you set the value type of an sp:arg when passing in a string via http would be helpfull, I have a nagging feeling this is the root of the problem. java.lang.reflect.InvocationTargetException     at org.topbraidcomposer.sparqlmotion.actions.AbstractExecuteSPARQLMotionAction$1.run(AbstractExecuteSPARQLMotionAction.java:148)     at org.topbraidcomposer.core.util.ThreadUtil$1$1.run(ThreadUtil.java:64)     at java.lang.Thread.run(Unknown Source) Caused by: java.lang.IllegalArgumentException     at java.net.URI.create(Unknown Source)     at org.topbraid.spin.sparqlmotion.engine.impl.ExecutionEngineImpl.merge(ExecutionEngineImpl.java:256)     at org.topbraid.spin.sparqlmotion.engine.impl.ExecutionEngineImpl.executeModule(ExecutionEngineImpl.java:149)     at org.topbraid.spin.sparqlmotion.engine.impl.ExecutionEngineImpl.execute(ExecutionEngineImpl.java:120)     at org.topbraidcomposer.sparqlmotion.views.console.SPARQLMotionConsole.execute(SPARQLMotionConsole.java:79)     at org.topbraidcomposer.sparqlmotion.actions.AbstractExecuteSPARQLMotionAction$1.run(AbstractExecuteSPARQLMotionAction.java:137)     ... 2 more Caused by: java.net.URISyntaxException: Expected scheme-specific part at index 14: publishedBook:     at java.net.URI$Parser.fail(Unknown Source)     at java.net.URI$Parser.failExpecting(Unknown Source)     at java.net.URI$Parser.parse(Unknown Source)     at java.net.URI.<init>(Unknown Source)     ... 8 more Root exception: java.lang.IllegalArgumentException     at java.net.URI.create(Unknown Source)     at org.topbraid.spin.sparqlmotion.engine.impl.ExecutionEngineImpl.merge(ExecutionEngineImpl.java:256)     at org.topbraid.spin.sparqlmotion.engine.impl.ExecutionEngineImpl.executeModule(ExecutionEngineImpl.java:149)     at org.topbraid.spin.sparqlmotion.engine.impl.ExecutionEngineImpl.execute(ExecutionEngineImpl.java:120)     at org.topbraidcomposer.sparqlmotion.views.console.SPARQLMotionConsole.execute(SPARQLMotionConsole.java:79)     at org.topbraidcomposer.sparqlmotion.actions.AbstractExecuteSPARQLMotionAction$1.run(AbstractExecuteSPARQLMotionAction.java:137)     at org.topbraidcomposer.core.util.ThreadUtil$1$1.run(ThreadUtil.java:64)     at java.lang.Thread.run(Unknown Source) Caused by: java.net.URISyntaxException: Expected scheme-specific part at index 14: publishedBook:     at java.net.URI$Parser.fail(Unknown Source)     at java.net.URI$Parser.failExpecting(Unknown Source)     at java.net.URI$Parser.parse(Unknown Source)     at java.net.URI.<init>(Unknown Source)     ... 8 more On Monday, 11 March 2013 21:40:25 UTC, John Perdoni wrote: Hi yet again I apologise if I am wasting your time if this turns out to be lack of knowledge ie a sparql problem.
