Answer 1

Parse error for certain parameter, you can find out which parameter is invalid by checking the submitted URL.

Try :
- Correct the invalid name of the parameter
- Or, the following example might be a solution / give you an idea :

struts.xml

<interceptor-stack name="defaultStack">
    <interceptor-ref name="params">
        <param name="excludeParams">dojo\..*,^struts\..*,jquery\..*</param>
    </interceptor-ref>
</interceptor-stack>

Excluding parameters

This interceptor can be forced to ignored parameters, by setting its excludeParams attribute. This attribute accepts a comma separated list of regular expressions. When any of these expressions match the name of a parameter, such parameter will be ignored by the interceptor.
