[jira] [Created] (GERONIMO-6330) NPE in CompositeELResolver
NPE in CompositeELResolver
--------------------------
Key: GERONIMO-6330
URL: https://issues.apache.org/jira/browse/GERONIMO-6330
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: specs
Affects Versions: 3.0-beta-1
Reporter: Jarek Gawor
Assignee: Jarek Gawor
When you create an application which contains a JSF mapping in your web.xml file, JSP (JavaServer *Pages*) files which contain an EL function, throw a NPE. Here is the web.xml changes I added to a small JSP application:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
After doing this and deploying the application, the following page throws an NPE:
hello.jsp:
Test: '${pageContext.getRequest()}'
Exception:
java.lang.NullPointerException
javax.el.CompositeELResolver.invoke(CompositeELResolver.java:225)
javax.el.CompositeELResolver.invoke(CompositeELResolver.java:225)
org.apache.el.parser.AstValue.getValue(AstValue.java:159)
org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:189)
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(PageContextImpl.java:985)
org.apache.jsp.hello_jsp._jspService(hello_jsp.java:63)
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
javax.servlet.http.HttpServlet.service(HttpServlet.java:668)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:433)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:389)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:333)
javax.servlet.http.HttpServlet.service(HttpServlet.java:668)

[jira] [Commented] (GERONIMO-6330) NPE in CompositeELResolver

Jarek Gawor commented on GERONIMO-6330:
---------------------------------------
The problem is that the CompositeELResolver was iterating over the resolvers array directly instead of relying on the size field.
Fix committed in revision 1327712.
