Layout tags don't handle huge inserted contents (layout definitions) well,
usage results in OutOfMemory errors
--------------------------------------------------------------------------------------------------------------
Key: STS-391
URL: http://mc4j.org/jira/browse/STS-391
Project: Stripes
Issue Type: Bug
Components: Tag Library
Affects Versions: Release 1.4.3
Reporter: Karel Kolman
Assigned To: Tim Fennell
I'm using the Stripes layout tag library and am experiencing difficulties
rendering huge web pages.
An example structure is the following (/WEB-INF/jsp/content.jsp file generates
approximately 13 megabytes of data)
<%@ taglib uri="http://stripes.sourceforge.net/stripes.tld"; prefix="stripes" %>
<stripes:layout-render name="/WEB-INF/jsp/layout.jsp">
<stripes:layout-component name="body-content">
<!-- either this -->
<stripes:layout-render name="/WEB-INF/jsp/content.jsp"/>
<!-- or this -->
<jsp:include page="/WEB-INF/jsp/content.jsp" flush="true"/>
</stripes:layout-component>
</stripes:layout-render>
This results in OutOfMemory errors being thrown (and page not being displayed),
the server has 512MB of heap space available.
Changing the code in LayoutRenderTag.java from
BodyContent content = getPageContext().pushBody();
getPageContext().include(this.name, false);
getPageContext().popBody();
getPageContext().getOut().write(content.getString());
to
getPageContext().include(this.name, false);
I am able to render the large jsp files inside the layout-render tags.
Could this somehow be fixed ? Could you consider adding an additional attribute
to the layout-render tag that would work without loading the whole contents of
the inserted subpage into a buffer ?
