[jsword-devel] JSword APIExample errors

I am currently trying to get my head around the JSword source. My Java knowledge is not extensive, and in fact, I am working on a Clojure wrapper on the JSword Java source.

The latest JSword code in the git repo fails to build with this message:

Results :

Failed tests:


  DwrBridgeMissingAssetsTest.testSearch:83 expected:<[Exo 5:4, 6:13, 26-27, 7:19, 8:5, 16, 12:1, 16:6, 32:1, Num 14:2, 26:59, 33:1, Jos 24:5, 1Sa 12:6, 8, Mic 6:4, Act 7:40]> but was:<[]>

Tests run: 769, Failures: 2, Errors: 3, Skipped: 13

If I checkout the JSword 2.1 release, it compiles fine. However, when I compile APIExamples.java and try to run it, I get:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: Defaulting to no-operation (NOP) logger implementation

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

The plain text of Gen 1:1 is In the beginning God created the heaven and the earth .

Exception in thread "main" java.lang.NullPointerException

        at org.crosswire.jsword.util.ConverterFactory.getConverter(ConverterFactory.java:51)

        at com.selfdidactic.sword.App.readStyledText(App.java:162)

        at com.selfdidactic.sword.App.main(App.java:462)

the code in question:

    public String readStyledText(String bookInitials, String reference, int maxKeyCount) throws NoSuchKeyException, BookException, TransformerException,



        Book book = getBook(bookInitials);

        SAXEventProvider osissep = getOSIS(bookInitials, reference, maxKeyCount);

        if (osissep == null) {

            return "";


        Converter styler = ConverterFactory.getConverter();

Any insight on this?
