It's strange. I remove the c:put, deploy the war, and it failed again. When
I took a look at the java code generated by the JSP, and it has the
following declaration
static private weblogic.jsp.internal.jsp.JspFunctionMapper _jspx_fnmap =
weblogic.jsp.internal.jsp.JspFunctionMapper.getInstance();
static {_jspx_fnmap.mapFunction("json:serialize",
org.apache.struts2.json.JSONUtil.class, "serialize", new Class[]{
java.lang.Object .class , java.util.Collection .class , java.util.Collection
.class , boolean .class , boolean .class });
}
So it is creating a Function Mapper for json:serialize that receives 5
arguments (Object, Collection, Collection, boolean, boolean). If one takes a
look at the API(
http://struts.apache.org/2.1.8/struts2-plugins/struts2-json-plugin/apidocs/org/apache/struts2/json/JSONUtil.html#method_summary),
the method serialize is overloaded, so there is a method that receives only
an object(The one that is declared on the TLD), and another one that
receives the same arguments defined on the JSP. It seems that the WebLogic
is ignoring the TLD, and it is just using another method instead of the one
indicated on the TLD, which is defined as follows
[...]
<function>
<name>serialize</name>
<function-class>org.apache.struts2.json.JSONUtil</function-class>
<function-signature>
java.lang.String serialize(java.lang.Object)
</function-signature>
</function>
[...]
Any idea of why it can behave that way? It's curious that on Linux it works
fine, it only fails on Windows.
