Can't load presentation due to JAXBException

Hi,

I am trying to use docx4j.net in my app, by using it from an assembly used as a plugin.

I use the nuget package docx4j.NET version 3.2.0.1, targeting "net452" (plain library project on framework 4.5.2). The dependencies added by nuget : IKVM 8.1.5717.0, slf4j-api 1.7.5, slf4j-NetCommonLogging 1.7.5.2.

When initializing my plugin, I followed samples (and some googling for classpath assemblies) :

            // Programmatically configure Common Logging
            // (alternatively, you could do it declaratively in app.config)
            LoggingNameValueCollection commonLoggingproperties = new LoggingNameValueCollection();
            commonLoggingproperties["showDateTime"] = "false";
            commonLoggingproperties["level"] = "INFO";
            LogManager.Adapter = new Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter(commonLoggingproperties);

            // Necessary, if slf4j-api and slf4j-NetCommonLogging are separate DLLs
            ikvm.runtime.Startup.addBootClassPathAssembly(
                System.Reflection.Assembly.GetAssembly(
                    typeof(org.slf4j.Logger)));
            ikvm.runtime.Startup.addBootClassPathAssembly(
                System.Reflection.Assembly.GetAssembly(
                    typeof(org.slf4j.impl.StaticLoggerBinder)));
            ikvm.runtime.Startup.addBootClassPathAssembly(
                System.Reflection.Assembly.GetAssembly(
                    typeof(org.slf4j.LoggerFactory)));
            ikvm.runtime.Startup.addBootClassPathAssembly(
                System.Reflection.Assembly.GetAssembly(
                    typeof(org.docx4j.jaxb.Context)));
            ikvm.runtime.Startup.addBootClassPathAssembly(
                System.Reflection.Assembly.GetAssembly(
                    typeof(org.apache.xalan.processor.TransformerFactoryImpl)));

I have also added a custom classloader to handle "docx4j.properties" file loading (stored as assembly resource), code is like PropertiesConfigurator.setDocx4jPropertiesDir.

Then I open my presentation :

PresentationMLPackage prez = (PresentationMLPackage)OpcPackage.load(new ikvm.io.InputStreamWrapper(inputstream));

Kaboom in the logs. Shortenned :

Can it be related to a different IKVM version between your generated assembly (IKVM 7.3.4830, according to nuget dependency) and the latest version (IKVM 8.1.5717.0) ?

If so, can you update to latest IKVM version ? Or what is the compilation workflow to generated docx4j.net from latest version of docx4j ?

Thanks

Hi,

Seams to be related to IKVM version. I have recompiled a docx4j with latest IKVM (see http://www.docx4java.org/forums/docx-java-f6/convert-docx4j-2-8-1-to-net-assemblies-by-using-ikvm-t1573.html) then goes OK.

The test I make : open a pptx file, convert it to SVG.

Seams to work.

That's right, you need to be using consistent version of IKVM.
