- Help using TexPadIs there anyone here who knows how to use TextPad for a programming editor?
I sure could use the help. The instructions in help don't really explain
what to do. It says I'm supposed to see something but it isn't there, i.e.
I'm supposed to click on "Configure" then "Tools" then "Add" and I'm
supposed to click on "Java SDK Commands" and that command is not listed.
What do I do??
Thanks

- Drawing ImageHi,
I am developing a login application in which i need to have an image
put on to a JFrame which has several internal frames. (The main frame)
when I use the graphics object, it draws up the image and it disappears
in a few seconds.
I tried to change the background color, but i see only a flash of the
color and it disappears.
It would be extremely helpful is someone could sort this problem for
me.
Thank you,
Sumit

- Java inherited annotationsHello all!
Some times ago the problem was raised... I and my collegs started to
use Java annotations and noticed that our annotations those was made
for java interfaces and their methods didn't accessible in inherited
classes and interfaces... I tried to use the metatag @Inherited but IMHO
it doesn't work correctly. Anyway we have made our own realization of
inherited Java annotations and shared it. So u can use it if you want.
It is free and open source. Can be downloaded from here:
http://www.fusionsoft-online.com/annotation.php

- Vendor independent data sourceI have an application that I deployed to WebSphere using the default
Struts datasource from it's action. I've been reading about this now
and it sounds like this is not the prefered way to make a database
connection pool. They suggest using the containers, but I want to
remain vendor independent and be able to deploy my application in any
container with little or no changes.
I know there must be a standard non-vendor specific way to create a
connection pool. Can someone tell me what that standard is? Searching
the web just provided me with about 100 different ways to do it, but I
want the "Java Standard" way to do this.
Thanks,

Because the source code and build infrastructure aren't included for either
the JAR or the native library in the source that Sun distributes(*). You
could copy the included Linux/Solaris JARs over, but then you need to build
the corresponding native library somehow.
* - Actually, the source is there, but its bundled up and there is no
build infrastructure.
Thats my recollection at least.

- Tomcat, Oracle, connection pooling, BLOBsI have a rather strange problem with Tomcat's connection pooling and
the Oracle JDBC driver when using BLOBs that seems to be related to
class loading.
My configuration:
Tomcat 5.0.27
Oracle 9i
ojdbc14.jar is in $CATALINA_HOME/common/lib (and nowhere else)
The datasource is configured in server.xml
Everything works perfectly as long as I don't configure the datasource
in the server.xml file (including reading/writing BLOBs).
Once I use the datasource configuration in server.xml everything
except Oracle's BLOB implementation works (means: I can access the
tables, insert, select etc., but I can't read/write BLOBs)).
The problem is with class loading:
System.out.println(getConnection() instanceof
oracle.jdbc.driver.OracleConnection);
System.out.println(getConnection().getClass().getName());
results in:
false
oracle.jdbc.driver.OracleConnection
So the connection is of the expected type, but the type has been
loaded with the wrong class loader. This leads to a ClassCastException
in the Oracle JDBC driver (createTemporary()).
As I told you the JDBC driver is in common/lib and nowhere else, so
the class should be available in the application code.
Any hints ?

- JSP Include IssuesI have a web page using an include file. I am passing params to the
include page using jsp:param but am having some difficulty.
Locally (Windows PC/Tomcat Server, JBuilder) I can include ™ in
the heading1 param - when I put this live (Linux/Tomcat Server) the
heading1 text is cut off after the &. There is no error message from
Java (unless it is a System.out.print type error).
Does anyone have any suggestions as to why this is not working and how
I can resolve it?
<jsp:include flush="true" page="/inc/nav.jsp">
<jsp:param name="heading1" value="Business Web Design:
<em>Functional, Findable, Accessible ™</em>" />
<jsp:param name="pageTitle" value="Home" />

- Corba java apllet client communication problemI hava a problem with communication between Java/Corba server based on JDK
ORB with Java/Corba client (applet)
based on the same ORB. I`m using IOR to localize server.
client`s ORB i initialize like that:
Dane proxy = null;
ORB orb = ORB.init(parent, null);
org.omg.CORBA.Object obj = orb.string_to_object(sIOR);
proxy = DaneHelper.narrow(obj);
server`s ORB i initialize like that:
ORB orb = ORB.init(args, null);
POA rootpoa = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
rootpoa.the_POAManager().activate();
DaneImpl oDane = new DaneImpl();
org.omg.CORBA.Object ref = rootpoa.servant_to_reference(oDane);
String ior = orb.object_to_string(ref);
It looks like that:
- if i`m trying to run applet throught web site from the same (192.168.0.1)
computer where Corba sever works
everything works fine, i write it in the browser->
http://192.168.0.1//TestCoraba.html
- if i`m trying to run applet throught web site from an other (192.168.0.2)
computer server receive method call
from client but client can`t receive server`s answer and stops, i write it
in the browser-> http://192.168.0.1//TestCoraba.html
Maybe you what i`m doing wrong.
Thanks form any help.

- C++ programmer stumbles over pass by value. Need advice.Here's a model of my problem. I see what's causing it (thinking in C++,
with pass by reference) but I don't see a Java way to solve it. Probably
because I'm so new to Java.
Here's the problem.
2 methods inside the same class. Method1 passes a String array to
method2, relying on method2 to process the string array and return a
String and a new String array for further processing back to method1.
public boolean method1 (String s1, other args)
{
//do some stuff
String [] sa1 = null; // to be created and returned by method2
String s2 = null; // to be created and returned by method2
Method2(s1, sa1, s2)l
//do some important stuff with sa1 and s2
return true;
}
// C++ type method (unfortunately)
private void method2 (String s1, String [] sa1, String s2)
{
//do some stuff
StringTokenizer st = new StringTokenizer(s1, "/");
String sRemainder;
sRemainder = st.nextToken();
s2 = st.nextToken(); // just a string to be returned
sa1 = sRemainder.split(","); // a string array to be returned
}
The eclipse debugger confirms that method 2 is processing the strings
exactly as I want it to. sa1 and s2 after the processing look great
inside method 2. But they're null after the return to method1. I assume
this is because sa1 and s2 are copies inside method 2 and they go out of
scope on the return. sa2 and s1 are created inside method2 but I need
them for further work in method 1.
I obviously coded this like a C/C++ programmer. What I'd like to know is
what's the conventional methodology (or programming idiom) for passing
back lots of stuff created in one method to it's caller? Feel free to
hack up the above example to show me how, if it's convenient.
Thanks in advance for your help/

- Validating parsed XML document against XML-schema*PROBLEM: how to validate parsed XML document against (parsed) XML-schema.
*IN: XML document as org.w3c.dom.Document, XML-schema as stream
*OUT: information if document is valid against schema. If document is not
valid DETAILED information about ALL errors (especially: node that caused
problem).
*Additional information:
- validation is performed quite often,
- XML-document object is changed quite often,
- XML-Schema is fixed.
- XML-document doesn't contain information about related XML-schema
(attr xsi:noNamespaceSchemaLocation)
- XML-Schema is available as file only when the application starts.
It means that schema can be loaded from a file only once.
- must works in Java1.4+
I've tried to implement it using JAXP:
//app start
SchemaFactory schemaFactory =
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Source schemaSource = new StreamSource(new File(schemaFile));
Schema schema = schemaFactory.newSchema(schemaSource);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(xmlFile);
//document is being changed usign .addChild etc.
//
Validator validator = schema.newValidator();
validator.setErrorHandler(new SimpleErrorHandler());
validator.validate(new DOMSource(document));
Unfortunately org.xml.sax.ErrorHandler gets only SAXParseException which
doesn't constant information about node that caused the problem.
Is there any other way to validated DOM-document?

java-programmer, If I write java program for Windows, will it run on a PDA or Cell Phone?
I guess that says it. I want to write a tool to use on my PC, but I
would like it to run on Linux, and a Palm or some other PDA, or a Cell
Phone. It would be a pretty simple program.
Thanks a lot...

The main Java language is OK, but handling the screen, the keys, and the
digitizer has to be done specially. The usable features available on
PDAs and phones are just too different from those of a regular computer,
and from one PDA or phone to another, for Java to cover.

Linux: yes.
PDA/Cell Phone - only if you use J2ME.

Is J2ME very different from java? I know programming C for a Palm
pilot required a very different approach than programming C for a PC,
due to memory,

J2ME is Java (Java 2 Micro Edition).
It is a scaled down version of Java intended for
devices with little memory.
There are some differences.

Thanks, I see your point. How then do developers handle it if the built
in java tools and guis don't work? Do they have to write custom code
for each PDA or cell phone? Are there APIs released by the phone
manufacturers?
Thanks much.

The good ones have 'em. As others have said, you need the Micro Edition.

- Help: Calling System.exit(0) inside finallyHello everyone,
I am trying to release windowing resource after a try-catch and found
that calling System.exit(0) inside finally may hide the an uncaught
exception. See example below.
What is the *right way* to use finally in this case?
--lc
PS.
(1) Problem with putting System.exit(0) at the end is that the JFrame is not
properly released when an uncaught exception (e.g. divide by zero) is
generated.
(2) Now if I move System.exit(0) inside finally clause, then JFrame is
released OK but the uncaught exception is not even reported!
import javax.swing.*;
public class FinallyTest extends JFrame {
FinallyTest(String title) {
super(title);

- NervousText vs NetBeans 4.1Hello,
I'm trying to learn how to create custom property editors for own javabeans.
I'm using sun's tutorial from webpage
http://java.sun.com/developer/onlineTraining/Beans/Beans4/nervous07.html
Everything is going well, i'm able to add this bean as new component
toNetBeans
by Palette Manager, i'm able to add this new component to jFrame,
but when I'm trying to change "text" property in properties editor,
NetBeans adds in initComponents() line:
nervousText071.setText(???);
Does anybody know what is the reason of malfunction? Is it my fault?
this is the property editor class:
package sun.beanbox.beans;
import java.beans.*;
public class NervousText07TextPropertyEditor
extends PropertyEditorSupport {
public String[] getTags() {
String values[] = {
"Nervous Text",
"Anxious Text",
"Funny Text",
"Wobbly Text"};
return values;
}
}
The rest of sources is on that webpage.
Many thanks in advance,

- JToolbar and XP look and feelDoes anybody know how to make buttons placed on the JToolbar to have XP type
border? I noticed that if I place a button on the JPanel I have button with
XP type, round conners border. If I place button on the toolbar there is no
XP border at all.

- Macintosh JTable cellBordersDoes anyone know how to make a JTable display with grid lines under the
Macintosh LnF?
I understand it has something to do with the following, but so far have
had no luck with it.
UIManager.getDefaults().put( "TableHeader.cellBorder", LineBorder );

Well, well, what have we here? Did you really think I wouldn't be
paying attention for something like this? Of course it's stooping
pretty low to create a whole new thread to attack someone (and
attacking them directly in the subject line, of course), even if it's
also bloody predictable.
Go play in traffic.

- DocBook Editor ComponentHi,
I am developing an application, which I want to distribute under GPL.
I am looking for a swing component, which will be able to edit docbook
documents in the way jeditorpane does it with HTML files.
Does anyone know anything, which would help me (so that I will not have
to write the component from scratch)?
I also thought about customizing Swing's editor pane. Can I modify the
HTMLEditorKit class so it's capable to handle Docbook files? Could I
then distribute this modified code under GPL or am I facing a conflict
with a kind of Sun license?

- Date calculationsJust a shor question concerning date calculations.
I want to take the current date, like Date currentDate = new Date(); then
subtract x number of days from it.
What I was thinking of doing was extracting the days, months and year from
currentDate and then make a method to subtract x from days if x is more
than the day in the month then I will have to rework it into the months and
possibly the year.
I was hoping there was an easier and better way of doing this.
Thanks

- deploy of servlet problemI am newbie to servlet and I am trying some simple example of servlet in
which I have written
1) a html form to get data saved in webapps/myplace/
2) a servlet which is to return the data got from the request.get of the
html form.
I have deployed the tomcat server, put the compiled servlet class in the
WEB-INF/classes and also make the web.xml file.
However, when I load the page to the servlet from the html form, and click
submit from the form which is supposed to link to the servlet, it returns
404 error which said it cannot load the page.
I would like to know what I have missed that lead to such problem.
Thousands Thanks

- How do I slow down my network?This may be a bit off-topic, but still:
I'm working with a Java client/server app.
In my test setup the client and server are connected via the 100 MBit
LAN, so bandwidth is virtually unlimited.
I want to test it in a more realistic setup, where the bandwidth is
only, say, 56 kbit/sec.
Is there a simple way to temporarily limit the bandwidth for test
purposes?
I have thought of putting a delay between every IP packet, on the
trasmitting or the receiving side, but in Java I don't have access to
individual packets, so I can't figure out where to insert the delay.
Maybe the solution should be made on a lower layer, like the ethernet.
