Thanks. I have used DocumentFilter and it works.

Now my scenario is when i do data validation, navigation to other screens should not be allowed unless valid input is entered in these textfields.

My window has Jtabbedpane which has 3 tabs. Above mentioned Jformattedtextfields is available in one of the tabs. If these textfields has: Duplicate value, empty or invalid data, validation is done and message is displayed.

If one of the text field has duplicate value/empty/invalid data and cursor is still available in the textfield and one of the tab panel is selected, then the validation message is displayed on that tabbed panel.

I need to restrict navigation and display this validation message on the panel where these textfields are available.

Please help me to resolve this issue.

Do i need to use HTMLEditorKit.Parser for reading. I tried using the parser.read() method, but shows errors. Tried the bow code:
HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0); HTMLEditorKit.Parser parser=new ParserDelegator(); parser.parse(reader, callback, true);
when above code is used for reading HTML, search logic itself doesn't work and same java.lang.ArrayIndexOutOfBoundsException: 88 exception as above occurs, this time at parser.parse(reader, callback, true);

Thanks for reading. Any help is highly appreciated.

Hi,
I am searching text from HTML and finding file names. Placing those names to JList. Searching is taking place properly. but java.lang.ArrayIndexOutOfBoundsException: 88 is thrown.

Find the code below:
public String search(JEditorPane editorPane, String word, String arg_strFilePath) { int countOccurances = 0; strGetFileName = arg_strFilePath; try { reader = new FileInputStream(arg_strFilePath); } catch (FileNotFoundException e) { e.printStackTrace(); } HTMLEditorKit htmlKit = new HTMLEditorKit ( ) ; editorPane.setEditorKit(htmlKit); HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument(); HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0); HTMLEditorKit.Parser parser=new ParserDelegator(); try { //parser.parse(reader, callback, true); editorPane.read(reader, htmlDoc); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } if (word == null || word.equals("")) { System.out.println("word == null " ); return null; } doc = editorPane.getDocument(); try { content = doc.getText(0, doc.getLength()).toLowerCase(); System.out.println("Content:\n " + content); } catch (BadLocationException e) { // TODO Auto-generated catch block e.printStackTrace(); } word = word.toLowerCase(); System.out.println("word= " + word); int lastIndex = 0; int wordSize = word.length(); System.out.println("wordSize= " +wordSize); while( (lastIndex=content.indexOf(word, lastIndex+1))!=-1) { countOccurances++; } System.out.println("countOccurances= " + countOccurances); try { reader.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } if(countOccurances!=0){ //Gets file name for matched text getlistElements(strGetFileName) ; filesMatching = strTemp; } return filesMatching; }

Please let me know why this exception occurs:

Hi,
Please let me know how to update JList with new elements. I have used the below code & it gives ClassCastException.

Hi,
I am working for creating help page. After search is done, i get the required texts which are placed in Jtextarea. On clicking each text, respective information page should be displayed in JEditorpane.
Please help me in knowing which listener i can use to click each text.

I have used document listener but not performing what i require.

//Adding document listener textArea.getDocument().addDocumentListener(this); //Implementing methods public void changedUpdate(DocumentEvent arg0) { System.out.println("INSIDE changedUpdate "); } public void insertUpdate(DocumentEvent arg0) { System.out.println("INSIDE insertUpdate "); if(arg0.equals("Global View")){ try { URL htmlURL = new URL("file:"+strNewPath+"\\img\\First.html"); editor.setPage(htmlURL); } catch (IOException ex) { editor.setText("Page could not be loaded"); } } } public void removeUpdate(DocumentEvent arg0) { System.out.println("INSIDE removeUpdate "); }
Please correct me.
