I’m using ME to develop a struts/tiles app and had no problems with the following page-welcome.jsp.

<%@ taglib uri=”/WEB-INF/struts-tiles.tld” prefix=”tiles” %>

<tiles:insert page=”myLayout.jsp” flush=”true”>
<tiles:put name=”title” value=”tbd” />
<tiles:put name=”body” value=”body-welcome.jsp” />
<tiles:put name=”footer” value=”footer.jsp” />
<tiles:put name=”menu” value=”menu.jsp” />
</tiles:definition>

The specified put jsp’s, and the underlying layout.jsp produced correctly formatted browser presentations

Then I tried to refactor my pages using using the apache <tiles:definition> tag. The page-welcome.jsp code in question follows:

<%@ taglib uri=”/WEB-INF/struts-tiles.tld” prefix=”tiles” %>

<tiles:definition id=”wynnContent” page=”wynnon-layout.jsp”>
<tiles:put name=”title” value=”tbd” />
<tiles:put name=”body” value=”tbd” />
<tiles:put name=”footer” value=”footer.jsp” />
<tiles:put name=”menu” value=”menu.jsp” />
</tiles:definition>
<tiles:insert beanName=”wynnContent” beanScope=”application” >
<tiles:put name=”title” value=”Welcome To Wynnon” />
<tiles:put name=”body” value=”body-welcome.jsp” />
</tiles:insert>

Deploy to the server seems to go OK, but execution of the app produces the following Exception page on the browser:

500 Internal Server Error:

I’m running XP with Orion 2 and ME on the same workstation. Is there
something special one must do to handle <tiles.definition …> tags,
in the struts servlet, or with the orion config? I’ve enabled the tiles
plugin in my struts-config, and I can’t see anything wrong with my
tag code (which is highly likely to be the problem, I admit).

Any assistance will be much appreciated.

Bill.

My Tiles knowledge is minimal. So you Tiles experts please chime in. From the stacktrace –

javax.servlet.jsp.JspException: Error – Tag Insert : No value defined for bean ‘wynnContent’ with property ‘null’ in scope ‘application’

I would start researching the tiles:insert tag for more background. Looks like the wynnContent bean is not defined at runtime.

<tiles:insert beanName=”wynnContent” beanScope=”application” >
<tiles:put name=”title” value=”Welcome To Wynnon” />
<tiles:put name=”body” value=”body-welcome.jsp” />
</tiles:insert>

Tiles tags API is defined here:
http://jakarta.apache.org/struts/userGuide/struts-tiles.html#insert

Tiles HOW-TO info defined here – see resources at bottom of page:
http://jakarta.apache.org/struts/userGuide/dev_tiles.html
