Re: HELP How to Display on JTextArea
Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
Use the JTextArea.append(...) method to append text the text area in tha ActionListener.
the new version is rumored to give the developers a little more access to displays, but it is still on an app by app basis. You would need to contact the developer of the app your interested in to see if they are going to implement it. (yes this includes apple, but they are most likely not going to give full access to display yet)

Please Help::How to display a Map with LIsts as Keys and Values using JSTL
Hi,
I need some assistance on how to display a Map in JSP using struts or core JSTL. I have a HashMap which has a List of keys and each key maps to a value of an ArrayList.i.e I have an ArrayList of taxCodes and each taxCode maps to a value of taxDetails which is an ArrayList of details for for that particular taxCode. I have some trouble to display each taxCode then display taxDetails for each taxCode. Here is my code below:
OrderDetails.java
package orderitems;
import java.sql.*;
import java.util.*;
public class OrderDetails {
private LineOder lineOrder;
private Map lineItems;
//returns an item number, key_item, from its unique keys

Help -- How to display Html text in a JEditorPane
I'm trying to display html in a JEditorPane (html is obtained by transforming Xml and Xsl). So after i do the transformation i have a string which is the html source to be displayed. But when i use editorpane.setText(htmlString) method it is displaying the html source in the editorpane. I also tried using the HTMLEditorKit's read method. Even then its displaying the html source. But when i store the html source as a html file and give the editorpane, the url of the html file, it displays properly.
I would be so grateful if u can help in displaying the html (which i have as a string) instead of the source...
Thank you so much...Hi, after struggling with problem, the solution seems to be to ditch the content type meta tag, JEditorPane seems to barf (silently!) on this...
So, to turn this off...
transformer.setOutputProperty(OutputKeys.ENCODING,"");
Cheers

Help,how to display a index in report
Dear all experts,i need to modify the following code so tat i can actually dispaly one more columm which is at pos0 for the index number. i add in the following code in bold,but it din give me any display...
IF WA_MVSTAT-MATNR EQ SPACE.
AT NEW MAKTX.
<b>counter = counter + 1.</b>
WRITE AT: <b>POS0 counter</b>,
POS1 WA_MVSTAT-MATNR,
POS2 WA_MVSTAT-MAKTX.
PERFORM DRAW_VLINE.
ENDAT.
ELSE.
AT NEW MATNR.
<b>counter = counter + 1.</b>
WRITE AT: <b>POS0 counter,</b>
POS1 WA_MVSTAT-MATNR,
POS2 WA_MVSTAT-MAKTX.
IF NOT P_SUM IS INITIAL.
PERFORM DRAW_VLINE.
ENDIF.
ENDAT.
ENDIF.
I've already add the columm in the print header,everything is working fine except for this INDEX NUMBER itself...pls help. thankshi Joan,
Probably the counter is getting overwritten because of the pos1.
check the values of pos0, pos1.
you might have declared counter as integer. the output length of integer is 10.
so, if pos0 is 1 , pos1 should b at least 11.

Hi Buterem,
I'm sorry to hear you are having issues with your MacBook Pro since your recent Yosemite update. I also apologize, I'm a bit unclear on the exact nature of the issue you are describing. If you are having intermittent but persistent responsiveness issues with your mouse or trackpad, you may want to try using Activity Monitor to see if these incidents correspond to occupied system resources, especially system memory or CPU. You may find the following article helpful:
How to use Activity Monitor - Apple Support
If the entire system hangs or locks up (for example, if the system clock freezes and stops counting up), you may also be experiencing some variety of Kernel Panic. If that is the case, you may also find this article useful:
