Stack Overflow in doView()-Method of GenericPortlet

[Matthias Bischof, modificado hace 13 años.]

Hi,

I tried to develop a new GenericPortlet and deployed it on Liferay 6.0.5 (on Tomcat). When the portlet is invoked for the first time, the processing of the portlet container ends in a stack overflow.
The portlet code looks like this (really nothing special...):
public class TestGenericPortlet extends GenericPortlet {

public void init() {
viewJSP = getInitParameter("view-jsp");
}

public void doView(
RenderRequest renderRequest, RenderResponse renderResponse)
throws IOException, PortletException {
include(viewJSP, renderRequest, renderResponse);
}

protected void include(
String path, RenderRequest renderRequest,
RenderResponse renderResponse)
throws IOException, PortletException {

PortletRequestDispatcher portletRequestDispatcher =
getPortletContext().getRequestDispatcher(path);

if (portletRequestDispatcher == null) {
_log.error(path + " is not a valid include");
}
else {
portletRequestDispatcher.include(renderRequest, renderResponse);
}
}

protected String viewJSP;

private static Log _log = LogFactoryUtil.getLog(TestGenericPortlet.class);

}

Is this a problem with Liferay 6.0? (I had the same problem with Liferay 6.0.4....)

Many thanks in advance for any help!

I created a bug report for this:
http://issues.liferay.com/browse/LPS-12196
Under comments you find a workaround for the problem.

Hi,

Generic portlet is working fine in liferay 6. Problem with only liferay-struts-portlet. If you send your portlet bundle, i could resolve your issue.
