In a Java web application I am using the Stripes framework on Jboss 4.2.3. In my JSP when I use

<c:import url="http://localhost:8080/contextPath/txts/someID" charEncoding="UTF-8"/>

It works great and the the contents are included in the output HTML. However, this does not work 

<c:import url="/txts/someID" charEncoding="UTF-8"/>

and it throws this error (the whole stack is too big to paste here, so I include the first few lines):

Any advice would be appreciated.

    The problem is that if the StreamingResolution is opened with a Reader, then it (naturally) opens a Writer to stream the output out. The c:import tag doesn’t care, and simply calls getOutputStream on the response.

    So, to mitigate this you should not use a Reader for your StreamingResolution, rather you need to create the StreamingResolution with a InputStream.

    The other option is to override the StreamingResolution.stream() method.

    Stripes is basically “doing the right thing” for you, but the c:import is raining on your parade.

    Thankfully, you have control over Stripes actions. Not so much over c:imports actions.
