- ResultSet and getArray()Then I have a result set named rs. I need that one column of ResultSet
rs will be in an array.
I've read about method getArray(), so i've thinked that my code will
be something like that:
================================
private void formWindowOpened(java.awt.event.WindowEvent evt)
{
ResultSet rs=mdbc.inviaQuery("select * from ... where ...");
try {
rs.next();
txtNome.setText(rs.getString("DB_COLUMN_NAME_1"));
rs.getArray("DB_COLUMN_NAME_2");
} catch {
// EXCEPTION
}
================================
Alas there's something that's go wrong and I get this error
(paziente.java552 is the line containing
rs.getArray("DB_COLUMN_NAME_2");) where's my mistake:
Exception in thread "AWT-EventQueue-0"

- creating an internalFrameI'm trying to create an instance of the JInternalFrame class, which
works fine.
I defined a JDesktopPane named desktop and I am able to add an internal
Frame to this JDesktopPane.
Inside this JInternalFrame (lets call ist Frame1) I got a button which
"should" open another JInternalFrame called Frame2 inside the same
desktop. But it doesn't work. The compiler says it doesn't recognize the
variable "desktop".
How do I get him to refer to the current instance of the JDesktopPane
I'm using? I have just one JDesktopPane as my workspace.
thx in advance,
Daniel

- ResultSet is closedI was testing my program and the above appeared in the output. I have
searched all classes in this particular folder and I do not even have any of
that coded. Does Java issue messages like that? Is it an error? My code ran
ok, just the message appeared.

- append string into FileHi,
I am having a big trouble while saving information into a file. I would
like append some information into file. However, each time that I try to
do this, the information of the file is replaced by the new information.
What is wrong with my routine?
File simFile = new File("simulations.txt");
//System.out.println("simulations: "+simFile.getAbsolutePath());
try{
if(simFile == null)
throw new IOException();
BufferedWriter output = new BufferedWriter(new FileWriter(simFile));
String text = simObj.getInfo();
output.append(text);
//output.newLine();
closeFile(output);
}catch(IOException e){
System.err.println("Cannot save Simulation into file");
}
thanks very much,

- EasyMock, JUnit, Java5 and generics...I'm trying to create a unit test. In the unit test I need to create a
mock java.util.List object. The List is going to be a collection of
WebForm objects, so the way it's declared using generics as
List<WebForm>. For my unit test I want to mock this List, but cannot
find a way to declare the mock object in my code. The declaration is as
follows:
private MockControl<List<WebForm>> controlWebforms;
private List<WebForm> webforms;
When I try to create the mock object, the following code is invalid:
controlWebforms = MockControl.createControl(List.class);
webforms = controlWebforms.getMock();
I get the error message "Type mismatch: cannot convert from
MockControl<List> to MockControl<List<WebForm>>" However, the following
declaration:
controlWebforms = MockControl.createControl(List<WebForm>.class);
webforms = controlWebforms.getMock();
is invalid. How do I reference the class for List<WebForm> to create my
mock object? Any ideas?

- Transactions QuestionsI have been reading about transactions in java and have some questions:
*) Which is mostly used: Container-managed transactions (CMT) or
Bean-managed transactions (BMT)? I dont have Entity Bean in my application.
*) Is this statement true: Use JTA only when the transaction involves more
than 1 database else use JDBC? If yes then how would you deal with this?
It would be nice if somebody points to a detailed tutorial about
transactions.
Thanks

java-programmer, Jar file exploring
Hi,
I want to read files and direcotories under a specific directory in a jar
file. In this way I can explore
the jar file interactively. The jar file contains thousands of files and has
no index.
So it is impractical to enumerate entries then filter them.
How can I do this? Thanks.

java-programmer >> Jar file exploring
Given that the JAR file format is such that the files can appear in any
order at all, you have no choice but to enumerate the entries.

HotSpot VM is faster than native Jet compiler once again? That's three

The WCECS 2008 is organized by the International Association of
Engineers (IAENG), a non-profit international association for the
engineers and the computer scientists. The congress has the focus on
the frontier topics in the theoretical and applied engineering and
computer science subjects. The WCECS conferences serve as good
platforms for our members and the entire engineering community to meet
with each other and to exchange ideas. Our last IAENG conference has
attracted more than one thousand participants from over 30 countries,
and our conference committees have been formed with over two hundred
and sixty committee members who are mainly research center heads,
faculty deans, department heads, professors, and research scientists
from over 20 countries.
All submitted papers will be under peer review and accepted papers
will be published in the conference proceeding (ISBN:
978-988-98671-0-2). The abstracts will be indexed and available at
major academic databases. The accepted papers will also be considered
for publication in the special issues of the journal Engineering
Letters, in IAENG journals and in edited books. Revised and expanded
version of the selected papers may also be included as book chapters
in the standalone edited books under the framework of cooperation
between IAENG and Springer, and between IAENG and America Institute of
Physics. For reference, the following post conference edited books of
our recent IAENG 2007 conferences have been scheduled to be published
by Springer in early 2008: Trends in Intelligent Systems and Computer
Engineering, Advances in Communication Systems and Electrical
Engineering, Advances in Industrial Engineering and Operations
Research, and Advances in Computational Algorithms and Data Analysis.

- Anyone have any experience with WebLogic 8?Hello, I have just installed WebLogic 814 for Solaris 8. The machine
is in a remote location, so I did all the installation remotely. My
question is, how do I create a data source? I am used to WL 5 with the
weblogic.properties file, but WL 8 seems different.
Any help is greatly apprciated, - Dave

- ANN: VRMLmagic - New Interactive 3D VRML Web/World Authoring ToolHi All,
We at Scintillating Graphics would like to announce the release of
VRMLmagic, our Interactive 3D Web Development Tool.
VRMLmagic is an easy to use tool for creating interactive 3D (Virtual
Reality) web pages in the VRML/X3D format(s). With its interactive 3D
development environment and a range of powerful tools, you'll find
yourself building interactive 3D worlds in no time. Take a look at our
web site for more info:
http://www.scintillatinggraphics.com.au/VRMLmagic/
Initially developed as part of a research project with the aim of
making a rapid development environment for the construction of 3D user
interfaces. It was clear that VRMLmagic's features (which enabled us
to quickly build interactive 3D interfaces) had enormous potential for
the mainstream web development industry, and in particular its ability
to bring 3D content to the web. We now hope this tool will enable you
to begin developing the potential of interactive 3D content for the
web.
The initial release is for the Windows (98 and above) platforms.
However we will soon be releasing versions for Mac OS X and other Unix
variants.
If you have any questions or would like additional information, email
us at email***@***.com

- Corrupt String or bytearray transport over RMIHello,
I have a strange problem when transporting a String and it's byteArray
between 2 JVM's on the same machine. The JVMs are seperately started
instances of IBM's 1.3.1 JVM which also comes with Websphere 4.5.
On JVM1, I have something along the lines of:
String jvm1String = "Some nice String";
byte[] jvm1bytes = jvm1String.getBytes("ISO-8859-1");
Now, I transport the string and the array through RMI toto JVM2. In
JVM2 I do the following:
jvm2bytes = jvm1String.getBytes("ISO-8859-1");
for (int i = 0; i < jvm2bytes.length; i++) {
if (jvm2bytes[i] != jvm1bytes[i]) return false;
}
This allways returns false. Manually checking the arrays shows that the
two byte arrays only differ somewhere in the middle, and only for about
2 bytes, regardless the content of the String. I have no idea what
would cause java to behave differently between the two jvm's.
My question is: Is this likely to be a bug in:
a) the transportation of Strings over RMI
b) the transportation of byte arrays over RMI
c) the way String.getBytes("ISO-8859-1") is implemented
d) the way I am using rmi or the getBytes() method
Due to requirements, I can not change the JVM, so I need to find a way
around this. I am using the bytearrays to verify data integrity.
Thanks in advance,
Rolf

- About Sun Developer Network SubscriptionHello,
I have downloaded the Sun Java Studio Creator from sun.com.
Now I am having a trial subscription of Sun Developer Network for 30
days.
But what are the advantages of it?
It seems that I can post queries about Sun Java Creator or Java Server
Faces technology only.
Can I have access to other technology documentation or it is meant for
some restricted technologies only?
PLease guide.

- How to re-asign a value to a variable in XSLTSorry Dudes,
I couldn't find an appropriate group to post about XML/XSLT issues.
I can only post to these close groups.
In most of programming languages are VERY easy to do:
int i = 0;
i = 3;
i = i + 1;
i += 2;
i++;
But how can I do these in XSLT?
I got error when I do
<xsl:variable name="i" select='0' />
<xsl:variable name="i" select="$i + '1' />
Can dudes (American West Coast's Term) out there can help?
Thank Q!
