Hi Paul
First of all, apologies for the long silence; I have been away. I am
creating the complete jar in maven using the "maven assembly plugin"
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<archive>
<manifest>
<mainClass>MyServer</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
If I run the target with jersey - 1.0.3 META-INF/services got a file named
"com.sun.jersey.spi.inject.InjectableProvider" with value
"com.sun.jersey.atom.abdera.impl.provider.injectable.ContentHelperProvider".
However, if I upgrade to jersey 1.4 and run the same target the contents of
the "com.sun.jersey.spi.inject.InjectableProvider" are as follows:
com.sun.jersey.core.impl.provider.xml.SAXParserContextProvider
com.sun.jersey.core.impl.provider.xml.XMLStreamReaderContextProvider
com.sun.jersey.core.impl.provider.xml.DocumentBuilderFactoryProvider
com.sun.jersey.core.impl.provider.xml.TransformerFactoryProvider
Now I can see that there is of-course nothing about the
"com.sun.jersey.atom.abdera.impl.provider.injectable.ContentHelperProvider"
in the "com.sun.jersey.spi.inject.InjectableProvider". Is it something to
do with the jersey configuration or wrong use of maven assembly build?
Any advice would be appreciated; I can still carry on with the jersey 1.0.3
but would like to use the newer version.
