- Print the output on the screen from a class that uses PrintWriter as an output stream.I 'm trying to output the result from a class called lexical, and CLASS
lexical uses PrintWriter as an output stream.
I successfully output the result to the file using the following
command
lexical.outStream=new PrintWriter( new
FileOutputStream("testing.txt") );
but, how can i output the result, and print the result on the screen? I
try the following
OutputStream out=new OutputStream();
lexical.outStream = new PrintWriter( new PrintStream(out));
but it doesn't work.
Any suggestion?

- Runtime.exec gives problem in unix environmentHi,
I have a problem with Runtime.exec() call.
I have used the following code:
String[] env = null;
Process wait = Runtime.getRuntime.exec(exeCmd , env ,workingDir);
.................
.................
My exe command uses some external application which has environment
settings.
If I give the env as null it takes the default environment settings
in windows and works fine in windows .But it doesnt work in UNIX,
it doesnt take the default environment settings in unix.
I have tried using String[] env = {""} , still it doesnt work in unix.
I want my code to work both on windows and unix.
Is there a solution???

- Custom dynamic SQl statementHello,
I am still having no luck with the creation of a custom sql statement.
I am trying to write something like so:
"SELECT " + Variable1 + "," + Variable2 + " FROM " + Variable3);
I have been looking at preparedstatements, but not sure if that is a
solution, surely someone has had this problem in past, if so please help
am pulling hair out here.
I get an error: Unable to load database driver
Details: java.lang.ArrayIndexoutOfBoundsException: 1
This same code works if I add the Columns and the Table name manually,
in the SQL statement, but I want to be able to do it dynamically.
Thanks if anyone can help.

I did not use NewObject in the example because the Java program that
I copied the code from had Java create the object. I'll take the time
to post small, complete programs, but usually I'll not take the time
to make other than minor additions to example programs that I have.
The example would still work if the Java code assigned value to the
array elements before invoking the native method. Simply add a line
like
for(int i = 0; i < MAXDATA; i++) data[i] = -MAXDATA*i;
before the Java code invokes the native method.

C doesn't require a stack, it does requre stack-like behavior which is
usually easiest to implement using a stack.
ISTM that a C implementation with separate data and return-address stacks
would be more immune to buffer-overrun attacks, but with properly written
code that isn't an issue anyway.

- lost reference to request inside beanhi
Sorry if this seems like a JSP 101 question,...
i've got a set of jsp's and beans that make up a website. most jsp
pages communicate with one bean, with no problem at all. a menu jsp
uses a separate bean, and a report page uses a third. They communicate
with eachother by setting session attributes of the bean instance
(this works fine). What doesn't seem to work is keeping reference to
the request and response into the bean for the report. It seems to
lose it at random points.
tags in all pages
<jsp:useBean id="bean_n" scope="session" class="Bean_n">
<% Bean_n.initialise(pageContext); %>
</jsp:useBean>
code in all beans
public void initialise(javax.servlet.jsp.PageContext PC ) {
Object obj;
super.initialise(PC); // defines log & abend routines. gets
connection
pageContext = PC;
servletContext = pageContext.getServletContext();
session = pageContext.getSession();
servletResponse = (HttpServletResponse)
pageContext.getResponse();
servletRequest = (HttpServletRequest)
pageContext.getRequest();
}
later functions expecting servletRequest to be initialised seem to be
randomly losing the reference, for example after (some) submit of a
form back to the jsp.
Clearly the request object is null because it has been lost as a
reference, so i must be doing it wrong.
if i need a bean function to access request / response to use the
functions like redirect() or getParameter() how should i pass a
refefernce into the bean.
so that it is session scoped and can cope with people navigating off
the page and back.
Any ideas?

Probably a memory leak then. A number of pieces of code in Sun's JRE can
leak class loaders (and hence all the classes and other data associated
with them). ThreadLocal is the common one. But java.beans and JDBC also
do it.
You can use a memory profiler to tell where the problem is. Googling can
give you more details.
It may be the permanent generation (code and interned strings) that is
running out. IIRC, -XX:MaxPermSize is the Sun option to increase that.

If the problem is a memory leak as Tom suggested, no.
At least, not unless you consider that doubling the
memory might allow the app. to run (roughly) twice
as long before failing, and that makes for 'a solution'.

Other options that may help you avoid the real problem until it pops up in
production at the least opportune moment:
-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled

It's something I lifted from NetBeans's config file examples.
Options like this are nearly undocumented, perhaps for a reason.

Yes. Them non-standard options are always to

possibly gone the next?).

- updating value in all sessionHi, I am a little stumped on this one, and I was hoping someone else
out there ran into and solved this problem. Using a J2EE servlet
container every client (browser) will acquire a session and certain
values will be stored in this session. However, if a certain
parameter is changed it should invoke a method in one of the beans in
the session, which all sessions will have. This sounds like more like
a type of event handler, but I am not aware of any non-gui event
listeners. Any ideas?

Brian

- Eclipse _mthclass$ problemI have an issue with Eclipse not adding a static Class called
_mthclass$ to my compiled class file and when I compile the same
source using Ant with jdk 1.3 or 1.4 it adds this _mthclass$. I read
that Eclipse has its own javac to compile class files and that you
cannot change this. My classes are now incompatible during
Serialization. Has anyone come across a way to get Eclipse to add this
class or a work around?

- Genercis adviceHello!
i've just read some docs about generics in Java, and i would like to do
a complete Canvas class. Here is my attempt:
import java.util.LinkedList;
import java.util.List;
public class Canvas {
private List<Shape> shapeList = null;
class Shape {
public void draw() {
}
}
class SubShape extends Shape {
public void draw() {
}
}
public Canvas() {
shapeList = new LinkedList<Shape>();
add(new SubShape());
drawAll();
}
public void drawAll() {
// TEH UGLYNESS !!!
List<? extends Shape> shapeList = this.shapeList;
for (Shape s:shapeList)
s.draw();
}
public void add(Shape s) {
shapeList.add(s);
}
}
From what i've understood:
- unbounded is for writing
- bounded is for reading
So basically, i have to use temporaries or i have to do a
"drawAll(bounded version)" wich is even worse.
I really hope i've missed something because i think this stink.
Any advice/explaination apreciated :)

You do seem to have a talent for finding the most astounding drivel ;-) Where

(P.S. I don't at all dispute that C++ is better described as "supporting OO"

- Write formatted XML to a fileHi,
I create the XML with DOM and save it to a file. But when I open such
file with Notepad, for instance, I see the XML file in one line - it
is not formatted/aligned. If I open it with IExplorer it looks fine.
I am looking for the way to save XML to a file so that XML would be
formatted.
The save code:
-------------------
doc.getDocumentElement().normalize();
DOMSource ds = new DOMSource(doc);
StreamResult sr = new StreamResult(out);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer trans = tf.newTransformer();
trans.transform(ds, sr);

- How to gray out the files in JFileChooser?I only let user select the directories,
not let user select the files.
So I
myFileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
That is fine, but user complain about that, they want to
make sure there are files under the directory.
If I do
myFileChooser.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
Then user will mistake select a file, which I don't let them select a
file. I need to popup a dialog says "Please select a directory only".
The idea thing is I can gray out the file names, so user can see
there are files under a directory, but they can't select any file,
only can select a directory.
Anyone out there has any idea how to gray out the file names in
JFileChooser?

cannot reference Z_DEFAULT before supertype constructor has been called
Does anybody know why this happens?

- GridBagLayout on JDesktopHi,
I have problems using GridBagLayout for positioning JInternalFrames on a
JDesktop.
For instance, I have 2 JInternalFrames and I neither set the size nor the
preferedSize of the InternalFrame because I thought my JInternalFrames would
get the size from the GridBagLayout-manager but it doesn't work at all.
[...]
desktop = new JDesktopPane();
gbl = new GridBagLayout();
desktop.setLayout(gbl);
content.add(desktop);
[...]
GridBagConstraints gbc1 = makegbc(0, 0, 1, 5);
gbl.setConstraints(treeIFrame, gbc1);
desktop.add(treeIFrame);
GridBagConstraints gbc2 = makegbc(1, 0, 4, 1);
gbl.setConstraints(tableIFrame,gbc2);
desktop.add(tableIFrame);
[...]
the makegbc is nothing more than:
private GridBagConstraints makegbc(int x, int y, int width, int height)
{
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = x;
gbc.gridy = y;
gbc.gridwidth = width;
gbc.gridheight = height;
gbc.insets = new Insets(1, 1, 1, 1);
return gbc;
}

- Error loading SolarisSerialHello
I tried running the examples on the following link on windows XP and
2000.
http://java.sun.com/products/javacomm/reference/docs/API_users_guide_3.html
Are those programs specific to solaris? Will they work on windows?
I get the following errors when i tried to run the programs:
E:\project\ckt download\Serial_port\trial2\classes>java SimpleWrite
