Re: [Resteasy-developers] RestEasy 3.0.8: javax.ws.rs.ProcessingException: could not find writer for content-type text/plain Error

[Ron S. <rs...@re...>]

Hi Dileepa,

This is a strange problem. 
org.jboss.resteasy.plugins.providers.InputStreamProvider, in the 
resteasy-jaxrs jar, can write a ByteArrayInputStream. By default, 
org.jboss.resteasy.spi.ResteasyProviderFactory should load all of the 
providers in the file META-INF/services/javax.ws.rs.ext.Providers, which 
is in the resteasy-jaxrs jar.

If you execute 
ResteasyProviderFactory.getInstance().isRegisterBuiltins(), you should 
get true. If you execute 
ResteasyProviderFactory.getInstance().getClientMessageBodyWriters() and 
ResteasyProviderFactory.getInstance().getServerMessageBodyWriters(), you 
should see InputStreamProvider. You could also try stepping through 
org.jboss.resteasy.plugins.providers.RegisterBuiltin.register(), which 
is responsible for loading the providers listed in 
javax.ws.rs.ext.Providers.

I don't know what's going on in your case. Maybe you'll see something 
suggestive if you try these things.

By the way, why do you think it's a dependency problem?
