In struts.xml replace 2.3 DTD version:
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
with 2.5:
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd">
Tags attributes
The id
attribute was replaced with var
attribute in the following tags.
<s:action>
<s:append>
<s:bean>
<s:date>
<s:generator>
<s:iterator>
<s:merge>
<s:number>
<s:set>
<s:sort>
<s:subset>
<s:text>
<s:url>
If you have something like that in your code:
<s:url id="url" action="login">
change it to:
<s:url var="url" action="login">
The <s:set>
tag name
attribute is replaced with var
attribute.
From:
<s:set id="str1" value="'string1 value'" /> <s:set name="str2" value="'string2 value'" />
to:
<s:set var="str1" value="'string1 value'" /> <s:set var="str2" value="'string2 value'" />
Also escape
attribute was renamed to escapeHtml
attribute.
From:
<s:property escape="true" var="someProperty"/>
to:
<s:property escapeHtml="true" var="someProperty"/>
Div tag
The <s:div>
tag was dropped.
Replace <s:div>
with plain HTML <div>
tag.
Field names
If you have field names which starts with single lower case letter, for example:
private String sTrng; public String getSTrng() {...} public void setSTrng(String str) {...}
change accessors to getsTrng
and setsTrng
.
Or better yet, change field names to not contain single lower case letter:
private String strng; public String getStrng() {...} public void setStrng(String str) {...}
