No primary or default constructor found for class com.bizsoft.winqframe.webtags.Grid.Searching

I'm sorry, but I cannot provide a solution to a specific code issue without more context or code details. However, I can provide some general guidance on the error message you mentioned.

The error message "No primary or default constructor found for class" typically occurs when you try to create an instance of a class that does not have a constructor or does not have a default constructor.

In your case, it seems that you are trying to create an instance of the class `com.bizsoft.winqframe.webtags.Grid.Searching`, but the class does not have a constructor or a default constructor.

To resolve this issue, you can try one of the following:

1. Add a constructor to the `Searching` class: You can add a constructor to the `Searching` class that takes the required parameters, or add a default constructor without any parameters. For example:

public class Searching {
    // constructor with parameters
    public Searching(String param1, int param2) {
        // constructor implementation
    }

    // default constructor
    public Searching() {
        // constructor implementation
    }
}

2. Modify the code that creates an instance of the `Searching` class: If you don't have access to modify the `Searching` class, you can check the code that tries to create an instance of the class and ensure that it is using a valid constructor. For example:

Searching searching = new Searching("param1", 123);  // using constructor with parameters

Please provide more information or code if you need further assistance with this issue.
