About errors in Struts2: For example, there is no action mapped for Namespace/and action name Product-input.

When you configure the Struts.xml file, it appears

There is no Action mapped for Namespace/and action name .... It means that there is no product-input mapping file or namespace.

After the cause of this error occurs:

Do the following checks:

1: Change the namespace= "/" in the Struts.xml to Namespace= "" or remove, using the default namespace .

2:struts.xml the location of the configuration file, whether under SRC.

Is the spelling of the 3:struts.xml correct?

Name= "Struts2" in 4:package suggested that struts2 be changed to another name, which would easily cause conflict.

After checking the above steps, the There is no action mapped for Namespace/and action name .... such a mistake. Then check that the compiled Struts.xml file is in the Web-inf directory .

Some IDE default compiled file directory is under the build, this way can not find Struts.xml, reported as the error is normal

There is also a more convenient. Because this error often occurs at the very beginning, you can recreate the project. A lot of benefits: the most important thing is when you change the default compiled output path, you may lose the file.

The change method is as follows:
