One solution to resolve the issue of an empty window name while upgrading from Struts2 2.5.28.2 to Struts2 6.1.1 is to add a default value for the window name in the JSP files.
You can add the following code in the head section of the JSP file:
<head>
<s:if test="#attr['windowName'] == null">
<s:set name="windowName" value="'Default Window Name'"/>
</s:if>
<title><s:property value="#windowName"/></title>
</head>
This code checks if the window name attribute is null and sets a default value if it is. It then uses the windowName attribute to set the title of the page.
Alternatively, you can also set the default window name in the Struts2 configuration file. You can add the following code in the struts.xml file:
<constant name="struts.ui.window.default" value="Default Window Name"/>
This code sets the default window name for all JSP files in the application.
