Vaadin lets you build secure, UX-first PWAs entirely in Java.
Free ebook & tutorial.
Vaadin 6.2.1 running on JBoss Portal 2.7.2
The class com.vaadin.terminal.gwt.server.AbstractApplicationServlet, which uses java.io.BufferedWriter, does not render portlet content when running on the JBoss Portal.
I fixed it with using java.io.PrintWriter.
Hi,
What exactly is the problem when using BufferedWriter? I do not have JBoss portal installed at the moment so I cannot test it but it sounds a bit strange that BufferedWriter would cause problems.
Hi,
I read somewhere this was a bug on jBoss portal 2.7.x or 2.7.2.
We solved it by changing some of the Vaadin code (method writeAjaxPage). Instead of
response.getOutputStream()
use
response.getWriter()
This worked for us.
