| Using Xtext and Code Generator without Runtime [message #1478261] |

Hi everybody,
I have developed a dsl and a generator for this dsl to generate some java files.
Now I want to use this generator to generate the java files but according a special file which must be an input and it must be available without Eclipse Runtime Version or Workbench.
Bests,
Parisa

Create a main class that reads your DSL files and invoke the generator. Then create a launch configuration. With the export wizard you can generate an executable Jar.
Alternatively provide a MWE2 workflow that does the process mentioned above. Then create a launch config for class org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher. Proceed like above.

Hi,
(1) adapt the generatorFragment in the workflow to create a java main
fragment = generator.GeneratorFragment auto-inject {
generateJavaMain = true
}
(2) regenerate the language. you find now a java main generated for the generator (you may use this one or adapt it for your needs)
(3) run the main once in eclipse
(4) use the export -> java -> runnable jar file wizard to create a all in one jar

Actually I have changed the main method like following:
public static void main(String[] args) {
String s="C:\\ ... \\org.xtext.example.pro1\\pro1\\pro1.pro1";
//if (args.length==0) {
// System.err.println("Aborting: no path to EMF resource provided!");
// return;
//}
Injector injector = new org.xtext.example.mydsl.Pro1StandaloneSetup().createInjectorAndDoEMFRegistration();
Main main = injector.getInstance(Main.class);
main.runGenerator(s);
}
but I get this error:
Exception in thread "main" java.lang.RuntimeException: Cannot create a resource for 'c:\ ... \org.xtext.example.pro1\pro1\pro1.pro1'; a registered resource factory is needed
at org.eclipse.xtext.resource.XtextResourceSet.getResource(XtextResourceSet.java:198)
and pro1.pro1 ist the file which I have created in Runtime Workbench.

This is my Pro1StandaloneSetup.java
/*
* generated by Xtext
*/
package org.xtext.example.mydsl;
/**
* Initialization support for running Xtext languages
* without equinox extension registry
*/
public class Pro1StandaloneSetup extends Pro1StandaloneSetupGenerated{
public static void doSetup() {
new Pro1StandaloneSetup().createInjectorAndDoEMFRegistration();
}
}

Hi,
I have tried it with mydsl but I have still the error
Exception in thread "main" java.lang.RuntimeException: Cannot create a resource for 'c:\ ... \org.xtext.example.mydsl\dslmodel\sample.mydsl'; a registered resource factory is needed
at org.eclipse.xtext.resource.XtextResourceSet.getResource(XtextResourceSet.java:198)
