Hello,
I was trying to run JSF (Mojarra implementation) with google apps
engine. I tried both 1.2 and 2.0 versions. My test page was simple,
just:
<f:view>
<h:outputText value="tralala"/>
</f:view>
Whenever I tried to view this page (under developer appserver) I
received such error:
HTTP ERROR: 500
jsp.error.beans.property.conversion
RequestURI=/test.faces
Caused by:
org.apache.jasper.JasperException: jsp.error.beans.property.conversion

org.apache.jasper.runtime.JspRuntimeLibrary.getValueFromPropertyEditorManager

I looked at compiled test_jsp.java, around line 123. It looked like
that:
_jspx_th_h_outputText_0.setPageContext(_jspx_page_context);
_jspx_th_h_outputText_0.setParent((javax.servlet.jsp.tagext.Tag)
_jspx_th_f_view_0);
_jspx_th_h_outputText_0.setValue((javax.el.ValueExpression)
org.apache.jasper.runtime.JspRuntimeLibrary.getValueFromPropertyEditorManager
(javax.el.ValueExpression.class, "value", "tralala"));
int _jspx_eval_h_outputText_0 = _jspx_th_h_outputText_0.doStartTag();
(...)
I guessed it had something to do with Jasper. So I entered the
directory google_app_engine/appengine-java-sdk-1.2.2/lib/shared/jsp.
There I deleted files repackaged-appengine-jasper-compiler-5.0.28.jar
and repackaged-appengine-jasper-runtime-5.0.28.jar. Then I downloaded
Tomcat (version 6.0.20) and I found in it files jasper-el.jar,
jasper.jar and tomcat-juli.jar. I copied them to google_app_engine/
appengine-java-sdk-1.2.2/lib/shared/jsp.
After that error dieappeared.
Have any of you encountered problem like that?
