Hi\
solution:at the core of static methods, you know the only class name is able to call the static method of it's own.so!You cannot call a non-static method using class, like JCatalog.getComponent()A non-static method can only be called with instance jcat.getComponent()I see that you have an reference maintained of type JCatalog named jcat. Make sure you initialize it somewhere OR set the instance using setter method. And use this instance to call the getComponent() method\

```
public abstract class JPanelTicket extends JPanel {    JCatalog jcat;    public JPanelTicket() {        jcat = new JCatalog();        initComponents();    }    public void init(){        jcat = jcat.getComponent(); //Here's the problem    }}
```

....................................................................................................alternatively.............................................................................................

```
public abstract class JPanelTicket extends JPanel {    JCatalog jcat;    public JPanelTicket() {        initComponents();    }    public void init(){        jcat = jcat.getComponent(); //Here's the problem    }    public void setJCatalog(JCatalog jcat) {        this.jcat = jcat;    }}
```
