ObjectTool

How can I unpack the zip file after downloading Ot.zip from sun website to install ObjectTool, it is mentioned that it can be unpacked by using Zip utility, which I do not know. my oprerating system is windows. Can anyone help?
Thanks!

You need a zip utility program, try a google search on zip.
Winzip or aladdin expander will do what is required.

Problem with initializing a class object

I believe your NullPointerException is happening at
this line (without seeing the line numbers in your
source file, which YOU can do):
>
System.out.println(webBrowser.getURL().toString());
Isn't that line 349, related to this part of the
stack trace?
atcom.ppowell.tools.ObjectTools.SimpleBrowser.generateWe
bBrowser(SimpleBrowser.java:349)
If so, then I'd conclude that webBrowser.getURL() is
returning null, so you can't invoke toString() on
that.It is line 349, it is the line that has System.out.println(webBrowser.getURL().toString()), Removing that line removes the NullPointerException being thrown, however, now I am suddenly unable to use setURL() as it constantly receives a null value when I am clearly sending it a non-null value.

}This code is supposed to handle a single selection from a JComboBox webAddressBox. The front-end functionality of this code blocks works just fine to the user, however, upon viewing the "behind the scenes action", I noticed that the overriden popupMenuWillBecomeInvisible() method within the anonymous inner class instance of PopupAdapter is being called 2 times upon the first time you select something from webAddressBox, 4 times the next time you select something, 8 times the next time, and so on..
Obviously this is a tremendous waste of resources to have it call that many times exponentially - it should only call once each time you select something from webAddressBox, but I can't figure out how to get that to happen.
What suggestions might you have to accomplish this? I already have an ActionListener that runs separately from PopupMenuAdapter that handles the user either clicking a JButton or hitting ENTER - this works just fine.
Thanx
Phil

is being called 2 times upon the first time youselect something from
webAddressBox, 4 times the next time you selectsomething, 8 times the next time, and so on..
Then you are adding the listener to the component
multiple times.WTO sigh.. thanx! :)

Help appreciated, I'm lost here.
Thanx
Phil

How do you do the Java equivalent of eval()?The language provides no support for that.
Reflection lets you call any method, where you
specify that method's name as a string and go through
a few other steps to build the proper Method object
with the proper args.
(http://java.sun.com/docs/books/tutorial/reflect/) It
won't let you just evaluate Java source code as a
script interpreter though. To do that, see
www.beanshell.org. Jython and I think Ruby on Rails
also give you scriptingin Java. Jython uses Python's
syntax, but gives you access to your Java classes. I
don't know ayhthing about RoR.I am going to look up PHP/Java myself as I know no Python right offhand (but probably could learn it in about 10,000 years). Tried to figure out reflection but couldn't figure out how to do what in PHP we do like this:
$msg = eval('JButton ' . $nameArray[$i][0] . ' = new JButton("' . $nameArray[$i][1] . '");');

Renaming packages has caused them to "no longer exist"

I am renaming my packages according to Java conventions..
Tried to rename "com.ppowell.tools.ObjectTools" to "com.ppowell.tools.objecttools"
However, upon doing so I am unable to find any of the classes in "com.ppowell.tools.objecttools"
I am getting "package com.ppowell.tools.objecttools does not exist" compiler errors by the boatload.
I am using NetBeans IDE 5.5
Please help!!
Thanx
Phil

UPDATE
I have no idea but everything's restored again..
however, NetBeans continues to show the package name
as "com.ppowell.tools.ObjectTools" when it is, in
fact, "com.ppowell.tools.objecttools". Can't find
anything in build.xml that tells me anything I can
understand, and everything compiles and runs now.
Just the weird NetBeans bug with the package names
being wrongly displayed that I can't seem to fix.you could try deleting the projects from the workspace (not the filesystem!) and re-importing them. don't know how you'd do that in netbeans, I've never used it

I suspect that you need to "clean" your html priorto
calling super.setText(). My guess is that you're
yanking nodes from beaneath Swing while it'strying
to render.
In addition to that, you may want to use JTidy to
clean up your html, and convert it to xhtml --again
prior to calling super.setText().Problem is that however I clean up the HTML, the
moment I try to reinsert back into the JEditorPane
using setText(), I get EmptyStackException or I'll
get NullPointerException or it just might work - same
problem, different exception(s).Ok this time I am simply using setText() instead of setPage(), but the results are, while consistent, they are consistently completely wrong. The browser appears blank every time, no HTML can be retrieved (you get a NullPointerException if you try), all the while I can verify that that original HTML from the remote site is correct, it never, ever, inserts into JEditorPane.

JEditorPane.setPage(URL url), then I want to clean up HTML, how?

According to http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4695909
the problem with the inconsistent ArrayIndexOutOfBoundsException that
I have been getting whenever I would go to a particular URL to put

containing HTML which contains a <META> tag and/or

Transfer all purchases from the iPad to iTunes on your computer, backup the iPad and then sync one last time.
Then go to Settings>General>Reset>Erase all content and Settings to completely erase the iPad.
Connect the new iPad to your computer and launch iTunes, restore from the backup of the old iPad and then sync with iTunes. You should be prompted to restore from the backup when you connect the new iPad to your computer's iTunes, but you can select it on your own as well.
Transfer purchases.

JButton is created "selected" even when I declare it not to be so

         * Generate value and conditions for {@link #backButton}
        private void generateBackButton() {
            SimpleBrowser.this.backButton = new JButton("<--");
            SimpleBrowser.this.backButton.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent evt) {
                    SwingUtilities.invokeLater(new Runnable() {
                        public void run() {
                            SimpleBrowser.hasClickedBack = true;
                            SimpleBrowser.this.currentHistoryIndex--;
                            SimpleBrowser.this.setURL(
                                    (URL)SimpleBrowser.this.actualHistoryURLVector.get(
                                    SimpleBrowser.this.currentHistoryIndex)

                            SimpleBrowser.this.processor.processURL(SimpleBrowser.this.getURL());
            SimpleBrowser.this.backButton.setSelected(false);
            SimpleBrowser.this.backButton.setFont(SimpleBrowserGlobals.FONT);
        }The moment this particular JButton is created it is created as "selected", even though I have done "setSelected(false)". It does not fire unless I click onto it, of course, but it appears as if I did and that's not good. Is there a way I can fix this?
Thanx

If you need further help then you need to create a

Self Contained, Compilable and Executable, Example

Don't forget to use the [url
