I have jFrame where I have to display data from database on button click. There are 4 buttons, first to display the first record in database, last to display the last record in database, next to display the next record and previous to display the previous record. I have done first and last record but what should I do to display the next and previous record.

I know that object is created. I checked it using jconsole. However it is not accessible with in the application. My second attempt was to regester the pool and then add it to the context and then when I need it read from there.

I need to implement an editable JComboBox. It should display a list of rivers from a database. However since the number of rivers is very large, the entries must be dynamically filled after the user has typed in three or more letters.
I have tried to solve this using a KeyAdapter. Everythings works. However after the user has typed in three characters, these three characters are selected in the Combobox. Of course when the user continues to type these chars will be replaced. I have so far not found a solution to deselect the characters and place the cursor at the end.
this.fliessgewaesserComboBox = new JComboBox<UisFliessgewaesser>(); this.fliessgewaesserComboBox.setEditable(true); this.add(this.fliessgewaesserComboBox, c); FliessgewaesserSuchenKeyAdapter fliessgewaesserSuchenKeyAdapter = new FliessgewaesserSuchenKeyAdapter(this); this.fliessgewaesserComboBox.getEditor().getEditorComponent().addKeyListener(fliessgewaesserSuchenKeyAdapter);
