上下文是grails app中的只读错误

Question

我尝试使用grails app http://grobid.readthedocs.org/en/latest/Grobid-java-library/中的示例来使用de GROBID JAVA API。 JAVA（Netbeans）中的以下代码运行良好：

public static void main(String[] args) {
    // TODO code application logic here

    String pdfPath = "/home/jose/plantilla_Informatica_2015 (ok).pdf";
    String pathGHome = "/home/jose/GROBID_COMPILED/grobid-home";
    String pathGProp = "/home/jose/GROBID_COMPILED/grobid-home/config/grobid.properties";

    try {
        MockContext.setInitialContext(pathGHome, pathGProp);
        GrobidProperties.getInstance();

        Engine engine = GrobidFactory.getInstance().createEngine();
        BiblioItem bi = new BiblioItem();

        String doc = engine.processHeader(pdfPath, false, bi);
        System.out.println(doc);

    } catch (Exception ex) {
        Logger.getLogger(GROBID.class.getName()).log(Level.SEVERE, null, ex);
    }
    finally{
        try{
            MockContext.destroyInitialContext();
        }
        catch(Exception ex){
            Logger.getLogger(GROBID.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

}

当我将具有相同集合依赖性的相同代码复制到grails时， 并将grobid-core.jar放在文件夹lib中，它给出了错误：

我的Grobid控制器：

import org.grobid.core.data.BiblioItem
import org.grobid.core.engines.Engine
import org.grobid.core.factory.GrobidFactory
import org.grobid.core.mock.MockContext
import org.grobid.core.utilities.GrobidProperties

class GrobidController {

    def index() {

    String pdfPath = "/home/jose/plantilla_Informatica_2015 (ok).pdf"
    String pathGHome = "/home/jose/GROBID_COMPILED/grobid-home"
    String pathGProp = "/home/jose/GROBID_COMPILED/grobid-home/config/grobid.properties"

        MockContext.setInitialContext(pathGHome, pathGProp)
        GrobidProperties.getInstance()

        Engine engine = GrobidFactory.getInstance().createEngine()
        BiblioItem bi = new BiblioItem()

        String doc = engine.processHeader(pdfPath, false, bi)
        println(doc)

        MockContext.destroyInitialContext()

    }

}

我的BuildConfig依赖项：

        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
        // runtime 'mysql:mysql-connector-java:5.1.29'

如果我构建相同应用程序的战争并使用

运行它

grails run-war target/GROB-0.1.war

效果很好!!!!

会发生什么？ 有帮助吗？ 谢谢你。
