Hey Ron, sorry for not replying to this.... I got distracted after your email and forgot to come back to it then :) Anway... not sure I follow :) As I see it, the issue on the client side will not be with "text/*" mime types since it seems to me that the issue is that the "text/*" types are coming back "wrapped" as a binary type in an InvocationResponse and the fact that it's "text/plain" underneath has been lost. I hope that makes sense :) So it seems to me like the Server to Client Marshal/Unmarshal process is missing a piece of info and an additional client side step. From memory, I think the http jbrserver-to-jbrclient response process for e.g. "text/plain" is as follows: | 1. [serverapp] return a String ("text/plain") response payload | 2. [jbrserver] wrap "text/plain" response payload in an InvocationResponse (serialized String I think) | 3. [jbrserver] change content-type to "application/something" because it's an InvocationResponse. | 4. [jbrserver] marshal response to client | 5. [jbrclient] unmarshal response from server | 6. [jbrclient] return payload from InvocationResponse - content-type is "application/something" | 7. [clientapp] Use binary response (serialized String I think)??? | So I was thinking there was a piece of info missing in the InvocationResponse that tells the JBR Client that the payload is actually a serialized object and the base content type is "text/plain". | 1. [serverapp] return a String ("text/plain") response payload | 2. [jbrserver] wrap "text/plain" response payload in an InvocationResponse | 3. [jbrserver] change content-type to "application/something" because it's an InvocationResponse - store "base-content-type" = "text/plain". | 4. [jbrserver] marshal response to client | 5. [jbrclient] unmarshal response from server | 6. [jbrclient] extract payload from InvocationResponse - it's a serialized object... base-content-type = "text/plain" | 7. [jbrclient] Deserialize payload to String - set response content-type back to "text/plain" | 8. [clientapp] Use String response ("text/plain") | Hope I'm making sense Ron :) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4247421#...
