How can we pass data from one JSF page to another JSF page?

To pass data from one JSF page to another JSF page, you can use the JSF Managed Bean session scope. Here is an example of how you can achieve this:

1. Create a Managed Bean class with session scope to hold the data that needs to be passed. For example:

```java
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

@ManagedBean
@SessionScoped
public class DataBean {
private String data;

public String getData() {
return data;
}

public void setData(String data) {
this.data = data;
}
}
```

2. In the first JSF page, set the data using EL expression in the Managed Bean:

```html

```

3. In the second JSF page, retrieve the data using EL expression from the Managed Bean:

```html

```

By using the session scope Managed Bean, the data will persist across different JSF pages within the same session. This method allows for passing data between different pages in a JSF application effectively and efficiently.
