I got it fixed. I made the mistake to clean the data of the JTable by nullifying the JTable. Appareantly the JScrollpane, where i add the JTable to, and the JTable went out of sync.

Thanks for your trouble.

hi everyone,

I construct a JTable with a DefaultTableModel. But after filling in some data in the table on the screen, my program can not find any data in the TableModel, everything is null. I understand from the Java API (5.0) that there is default a TableModelListener. Does anyone how an idea how this is possible ??

Thanks for the help

The code is below:
instantiating the table -->
private JTable getIngredientenTable() { if (ingredientenTable == null) { Object[] columnNames = { "ingredient", "hoeveelheid", "eenheid" }; tabelModel = new DefaultTableModel(columnNames, 20); ingredientenTable = new JTable(tabelModel); ingredientenTable.setModel(tabelModel); } return ingredientenTable; }

retreiving data

HashSet ingredienten = new HashSet(); DefaultTableModel ingredientenData = (DefaultTableModel) getIngredientenTable().getModel(); for (int i = 0; i < ingredientenData.getRowCount(); i++) { if (ingredientenData.getValueAt(i, 0) != null && ingredientenData.getValueAt(i, 1) != null && ingredientenData.getValueAt(i, 2) != null) { String naam = (String) ingredientenData.getValueAt(i, 0); double hoeveelheid = (Double.parseDouble((String) ingredientenData .getValueAt(i, 1))); String eenheid = (String) ingredientenData.getValueAt(i, 2); Ingredient ingredient = new Ingredient(); ingredient.setNaam(naam); ingredient.setHoeveelheid(hoeveelheid); ingredient.setEenheid(eenheid); ingredienten.add(ingredient); } }

problem was in the <c:import> tag. When I add the attribute charEncoding with the value utf-8 the problem was solved. I did a recursive import in this jsp file(mijnxtranet/notifylevel.jsp). The complete code is:
What a bit strange is that the directive is overruled by the import attribute.

Hoi,

I got a problem with displaying the character �. The code of the jsp is:

<c:out value="${someproperty}" escapeXml="false"/>

The static content in the JSP displays the � correctly, but in the out-tag the character is misformed. I have set the page encoding and contentType of the page in utf-8 and the string someproperty correctly shows an � with debugging, but somewhere in the translation from the controller to the view the character is misformed. Has anyone an idea what happens ??

Thanks Haiko

Hi,

I am just building an ordinary Java client-program with Eclipse. I run into a problem when I am debugging. While debugging Eclipse steps through the code normally, until it comes to giving the initiative to the user. Eclipse does not generate my Swing composed screens. I got the message "source not found" on a Swing component. When I try the button "Change Attached Source" it points to a folder rt.jar of Eclipse which does contain the Swing component . Is there something wrong with my settings or is this the behaviour of Eclipse ?? Does anyone have the same problem ?? Would be thankfull for your help

thanx, that fixed the problem. I have added weightX constraints and that did the trick.

Gr. Haiko

Michael, is it illegal to post on two different forums ?? And if not, isn 't there a ex-Stasi meeting you should attend ?

Hi,

I am having some trouble with JTextArea. I insert Strings by using the append() method,

for (int i = 0 ; i < ing.length - 1; i++ ) {
gekozenIngredienten.append((String )(ing[ i ] + ", "));

and that causes the JTextArea to grow in width. But when I am setting Linewrap to true my GridbagLayout turns in some really ugly screen. Does anyone know how to add Strings to a JTextArea without the Area to grow in width ?? Or setting LineWrap to true without my GridBagLayout going of the screen ?

Thanx Haiko
