How can I display a tree structure?

I would like to display a tree stucture, but don't want to use the JTree look. I would like the tree to look something like the following (but with boxes around the names, and arrows point from children to parent):
            --- child1
root ---|
                                --- child3
            --- child2 --|
                                --- child4Is there a class already out there I can implement and use for this? Or do I basically have to start from scratch?

It strikes me that JTree should have a setHorizontalLayout() feature... But scratch never was a bad place to start, was it?

How can I display contacts in a relationship

I have companies in my CRM. I have a customers/contacts in the CRM I have tied as a relationship with each companies. How can I display all the records/contacts associated with a company? I have a already created a secure zone, so the company user would have logged in. Is this possible? If not, any workaround?
The only workaround I thought of is to use webapp to import the company data and create another web app containing the employees data. Then link both tables/webapp using datasource. But the way the client's data is structured could create a lot of problems going forward.
Any suggestion, help will be appreciated

The relationship feature and how companies work currently in BC is really limited. It is an association and not true relationships at the moment. You cant output a company and show all its relationships at the moment.

How can I display XSLT transformer errors on a web page ?

Hi,
I have some JSP pages that access DB, create an XML based on DB data and then transform it into HTML through an XSLT stylesheet. Developing the XSL code it's easy to make mistakes and generate errors on trasformation, but what I receive on the web page is only a "Could not compile stylesheet" TransformerConfigurationException, while the real cause of the error is displayed only on tomcat logs. This is the code for transformation:
static public void applyXSLT(Document docXML, InputStream isXSL, PrintWriter pw) throws TransformerException, Exception {
        // instantiate the TransformerFactory.
        TransformerFactory tFactory = TransformerFactory.newInstance();
        // creates an error listener
        XslErrorListener xel = new XslErrorListener();
        // sets the error listener for the factory
        tFactory.setErrorListener(xel);
        // generate the transformer
        Transformer transformer = tFactory.newTransformer(new SAXSource(new InputSource(isXSL)));
        // transforms the XML Source and sends the output to the HTTP response
        transformer.transform(new DOMSource(docXML), new StreamResult(pw));
}If an exception is thrown during the execution of this code, its error message is displayed on the web page.
This is the listener class:
public class XslErrorListener implements ErrorListener {
    public XslErrorListener() {
    public void warning(TransformerException ex) {
        // logs on error log
        System.err.println("\n\nWarning on XEL: " + ex.getMessage());
    public void error(TransformerException ex) throws TransformerException {
        // logs on error log
        System.err.println("\n\nError on XEL: " + ex.getMessage());
        // and throws it
        throw ex;
    public void fatalError(TransformerException ex) throws TransformerException {
        // logs on error log
        System.err.println("\n\nFatal Error on XEL: " + ex.getMessage());
        // and throws it
        throw ex;
}When I have an error in the XSL stylesheet (for examples a missing closing tag), I can find on tomcat logs the real cause of the error:
[Fatal Error] :59:10: The element type "table" must be terminated by the matching end-tag "</table>".
Error on XEL: The element type "table" must be terminated by the matching end-tag "</table>".but on my web page is reported just the TransformerConfigurationException message that is:
"Could not compile stylesheet".
How can I display the real cause of the error directly on the web page?
Thanks,
Andrea

This code is part of a bigger project that let developers edit XSL stylesheets through a file upload on the system and we can't impose the use of any tool for checking the xsl. So, I need to display the transformer error on the web page.I see. This code is part of an editorial/developmental tool for developers to create and edit XSL stylesheets.
As part of the editorial process, XSL errors during editing can be considered a normal condition. In other words, it is normal to expect that the developers will generate XSL errors as they are developing stylesheets.
In this light, handling the XSL transformation errors is a business requirement that you need to handle. Using the Java Exceptions mechanisms, e.g. try / catch are inappropriate to handle business requirements, in my opinion.
I suggest that you look at how you handle the occurence of XSL errors differently than what you currently have. You need to:
(1) capture the Transformation exception on the server;
(2) extract the message from the exception and put it into a message that can be easily understood by the user;
The current error message that you have going to the web browser is not useful.
And you should not have the Transformation exception sent to the web browser either.
What you are attempting to do with the exception is not appropriate.
Handle the Transformation exception on the Business tier and use it to create a useful message that is then sent to the Presentation tier. In other words, do not send Java exceptions to web browser.

How can I display True/False in my dropdownlist as "Yes" and "No"?

Hi All,
I want to bind a dropdownlist to a boolean value (so it's either true or false). I'm particularly interested in using two-way binding to when the user changes from "yes" to "no" the boolean value automatically changes from "true" to "false." But, I want the user to see "yes" and "no" as the options, rather than "true" and "false".
How can I display "yes" and "no" and still take advantage of binding? Or can I not use binding in this circumstance?
-Josh

Solution 1:
In order to display Yes/No for True/False, you may specify labelFunction for the dropdownList.
In MXML:
<s:DropDownList labelFunction="myLabelFunction" />
In actionscript:
private var arr:ArrayCollection = new ArrayCollection(["true","false"]);
            private function mylabelFunction(item:Object):String
                if(item.toString() == "true")
                    return "yes";
                else return "No";
OR
Solution2:
may be u can try making an array collection like
private var arr:ArrayCollection = new ArrayCollection([{label:"yes",value:"true"},{label:"no",value:"false"}]);
and specify labelField for the dropdownList like
<s:DropDownList labelField="label" dataProvider="{arr}" />

How can I display & split the audio & video from the same digitized clip?

I digitized a scene into iMovie that I edited on a professional system which I don't have access to anymore. The whole scene is 1 clip. Now I see a few tweaks that I want to make, so I was hoping to do them in iMovie.
I want to "pull up" the audio in one section - meaning I want to take cut about 20 frames of audio from the end of a shot, and then move all the other audio up to fill the hole. To compensate for the missing 20 frames, I'll cut video off the head of the next shot. Some call this prelapping. Some call it an L-cut. Some call it asymmetrical trimming. Either way, I can't figure out how to do it in iMovie.
My clip appears in the timeline as one track - a single track that contains the video and 2 audio tracks. How can I display the audio that's tied to the video on its own track? Then I think I could split audio & video wherever I wanted and trim things up - but I can't figure out how to do it.
Am I asking too much of this software?
BTW, I never see the option to "Split audio clip at playhead". I'm not displaying clip volume or waveforms. Choosing to display waveforms doesn't show me anything. Maybe iMovie thinks I'd only want to see waveforms of audio that isn't tied to my video-and-audio clips?
Thanks in advance for any help...

Jordon,
"Am I asking too much of this software?"
No, you're not.
You first want to select your clip(s) and choose Advanced>Extract Audio.
This will copy the audio from the video clip and place it on one of the two separate audio tracks while lowering the audio level to zero in the original video track.
You can now edit and move the audio independently of the video.
With the audio clip selected, you'll find you now have access to Edit>Split Selected Audio Clip at Playhead.

How can i display a list of all the names stored in the Mail app?

When sending an email, the program shows a list of names according to the first and subsequent letters that I type into the To: field. There are times I cannot recall someone's email user name. How can I display a complete list of all the names Mail has stored? I know that I can go to the To: field then type in the letter A, then write down all listings under A, and then repeat for each letter of the alphabet, but there should be an easier method.
I have perhaps dozens of names in Mail, but only five names in Address Book, so the latter does me no good.

How can I get the XML structure from a flat structure?

Hi all,
in my XI SP 12 I use a JMS adapter to read information using the WebSphereMQ transport protocol.
The structure that I receive have this format:
<Name_A.KeyFieldValue><Name_A.fieldName_A1_Value>...<Name_A.fieldName_AN_Value>
<NumberRecordType_B><NumberRecordType_c>
<Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value>
<Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value>
<Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>
<Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>
the problem is that in this structure each line is not separated by a carriage return or a comma, I have all the information in a single line:
<Name_A.KeyFieldValue><Name_A.fieldName_A1_Value>...<Name_A.fieldName_AN_Value><NumberRecordType_B><NumberRecordType_c><Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value>...<Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value><Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>...<Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>
and the customer don't want to insert a line separator.
Then, the question is:
How can I get the XML structure from this structure?
If possible, I don't want to develop new Module and add it in the JMS Module Sequence.
PS I have already read the article "How to Use the Content Conversion Module with the XI 3 J2EE JMS Adapter.pdf" and it doesn't seem to help me.
Best Regards,
Paolo

To get context parameters from your web.xml file you can simply get the ActionServlet object from an implementing action object class. In the perform (or execute) method make the following call.
ServletContext context = getServlet().getServletContext();
String tempContextVar =
context.getInitParameter("<your context param >");

How can I display more than one value in Calendar ?

Hi,
the standard (example) script allows for the display of one value only (as I understood). How can I display two or three values, from the very same table ? Students of mine during an HTMLDB workshop in Leipzig did ask that question.
Do we have a more detailed docum. on the use of the calendar ?
pls kindly advise. TIA.
Bernhard

my solution:
Source fo the calendar starts:
snip>
declare
q varchar(32767) := null;
begin
q := 'select "ETA", <--- Date Field and concatination of fields as follows:
"SCHIFFSNAME"|| "ETA_TIME"|| "TERMINAL"||''(br*)'',
null,
null,
null,
null
from "#OWNER#"."SCHEDULE"'; . . . . . . .
snip>
comment on (br*) - you have to use "<" and ">" instead of "( " and ")" to have the "break/new line effect"
