Why can't I add items to the database?

How to write a JcomboBox selected item to a database?

• I'm playing around with openbravopos application in java and I need a little help please. I made a ComboBoxModel to have several items I have something like this: prodtypesent = dlSales.getProductList(); prodtypemodel = new ComboBoxValModel(); prodtypemodel.add(AppLocal.getIntStrin… prodtypemodel.add(AppLocal.getIntStrin… prodtypemodel.add(AppLocal.getIntStrin… prodtypemodel.add(AppLocal.getIntStrin… m_jProductType.setModel(prodtypemodel)… And it's working fine; it's writing to the database the respective strings when selected. My question is that I have to write to the database not the string but The first letter of it: Something like string combo.others=Something what I need is to write S in the database. Can anyone help me out?

• Answer:

  I'm not sure I understand. Do you want just the first letter of a Java String? I've never used Openbravo POS but if it lets you use regular Java, you can just substring the String? String others= "Something"; others.substring(0,1); Not all your example code is displaying but if "AppLocal.getIntStrin…" returns a string, could you just: AppLocal.getIntString .substring(0,1) (remove the space before the . period above)
