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

[Dileepa J. <dil...@gm...>]

Hi All,
I'm developing a connector to Apache ManifoldCF and in my connector I'm
using RestEasy 3.0.8 Final version. When I invoke the Rest API in a
standalone java class (Main method) it works, but when I added the my
component jar with all dependencies (including RestEasy 3.0.8 related
dependencies: )  to ManifoldCF I keep getting below dependency error in
runtime.
I think it's due to some cyclic dependency issue with ManifoldCF and
RestEasy 3.0.8 used in my component.
I tried out this in both ManifoldCF 1.8 and 2.1 both get the same error.

Can someone please give me pointers on what dependencies I should resolve?

[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?

Hi Ron,

Thank you very much for your reply. I will go through the steps you have
mentioned to figure out the problem.

I thought it's a dependency issue because, ManifoldCF also has RestEasy
dependency lib which is of a different version and I think at runtime my
connector get's wired to the RestEasy lib from  ManifoldCF instead of the
rest easy 3.0.8 dependency library inside my connector.

As a work around I used Jersey Rest client for my connector and proceeded
with the development. But it's good if I can sort out this issue and use
RestEasy.

Thanks,
Dileepa
