Hi All,

When deploying my apps which is using Axon Framework on Eclipse Virgo, I sometimes get the following exception:

Caused by: java.util.ServiceConfigurationError: org.axonframework.serializer.ContentTypeConverter: Provider org.axonframework.serializer.converters.ByteArrayToInputStreamConverter not a subtype at java.util.ServiceLoader.fail(ServiceLoader.java:231) at java.util.ServiceLoader.access$300(ServiceLoader.java:181) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:369) at java.util.ServiceLoader$1.next(ServiceLoader.java:445) at org.axonframework.serializer.ChainingConverterFactory.<init>(ChainingConverterFactory.java:51) at org.axonframework.serializer.AbstractXStreamSerializer.<init>(AbstractXStreamSerializer.java:106) at org.axonframework.serializer.AbstractXStreamSerializer.<init>(AbstractXStreamSerializer.java:81) at org.axonframework.serializer.AbstractXStreamSerializer.<init>(AbstractXStreamSerializer.java:70) at org.axonframework.serializer.xml.XStreamSerializer.<init>(XStreamSerializer.java:53) at org.axonframework.contextsupport.spring.FileSystemEventStoreBeanDefinitionParser.doParse(FileSystemEventStoreBeanDefinitionParser.java:76) at org.springframework.beans.factory.xml.AbstractSingleBeanDefinitionParser.parseInternal(AbstractSingleBeanDefinitionParser.java:85) at org.springframework.beans.factory.xml.AbstractBeanDefinitionParser.parse(AbstractBeanDefinitionParser.java:59) at org.springframework.beans.factory.xml.NamespaceHandlerSupport.parse(NamespaceHandlerSupport.java:73) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1438) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1428) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.parseBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:195) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.doRegisterBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:139) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.registerBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:108) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.registerBeanDefinitions(XmlBeanDefinitionReader.java:493) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:390) ... 21 common frames omitted

I’m using axon 2.4.3 and Eclipse Virgo Jetty Server 3.6.4.

Any help would be greatly appreciated.

Thanks & Regards,

Sounds like there may be more than 1 Axon on your classpath.

Hi Allard,

There’s only 1 Axon deployed. Moreover it works fine in non-OSGI environment, it also works if launched from Eclipse’s OSGI framework launcher.
The Spring framework version is 3.2.5

Thanks & Regards,

Apparantly, the ServiceLoader sees a difference between the interface class used to call load() and the interface implemented by the service class.
No idea how to solve this. I’m not an osgi expert.

Cheers,
