Hey folks,
I am new to Apache Isis and this Community, so please don't be too harsh
with me.
I want to create a button, which downloads a file. I already implemented
it for Apache Wicket, now I wanted to know if there is a chance using it
with Isis.
I'm trying to use the org.apache.wicket.request packages for that, which
are in the org.apache.isis.viewer.
But as soon as I import those classes I get this error:
javax.servlet.ServletException: Filtered request failed.

This is the button that I try to make:
public Car generateTxt(){
getRequestCycle().scheduleRequestHandlerAfterCurrent(
new ResourceStreamRequestHandler(new
AbstractResourceStreamWriter() {
@Override
public void write(OutputStream output)
throws IOException {
try {
fileCreator.generate(output,
"login", "password", Car.this);
} catch (IOException |
KeyManagementException ex) {
}
}
})
.setFileName("car.txt")
.setContentDisposition(ContentDisposition.ATTACHMENT)
);
return this;
}
Is there any way how I can get an OutputStream like this?
Best Regards,
Torsten
