Dependencies

Update Struts dependencies to 2.5.

Remove the following plugin dependencies because they were dropped and aren't supported anymore.

  • Dojo Plugin
  • Codebehind Plugin
  • JSF Plugin
  • Struts1 Plugin

StrutsPrepareAndExecuteFilter

The org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter was moved to org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter.

In web.xml replace this:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

with that:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

DTD

Struts DTD was updated to 2.5 version.

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'" />

 

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) {...}
