- Call for Papers: World Congress on Engineering and Computer Science WCECS 2008CFP: World Congress on Engineering and Computer Science WCECS 2008
From: International Association of Engineers (IAENG)
WCECS 2008: San Francisco, USA, 22-24 October, 2008
http://www.iaeng.org/WCECS2008
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.

- 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?

- 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

- 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

java-programmer, How to re-asign a value to a variable in XSLT
Sorry 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!

You really shouldn't, even if you can.
Here's a great explanation why.
[quote src=http://www.xslt.com/html/xsl-list/2002-04/msg00185.html]
However, it's very dangerous to use extension functions or extension
elements that have side-effects in XSLT, such as counters or
extensions that read and update databases. This is because XSLT is
designed around the basic assumption that you can evaluate the same
expression multiple times without affecting the result of that or
other expressions.
[/quote]
More points made there, too. Check out the full link.

As the previous poster said as well, XSL is designed as a Meta Language, a
pure functional language that does not allow for so-called 'side-effects'.
Such languages are purely declarative in nature, allowing its
interpreters/compilers for any valid possible optimization that the
interpreters/compilers can come up with and no unpredictable side-effects
are introduced.

- getting hostname from NT machine via CitrixHi All,
I don't know if any one can help or has any ideas about this.
We are writing a web based application which will run on a Unix box. It will
be accessible only via a login to Citrix from client machines. We have
achieved a transparent login to the application (running in Tomcat) using an
LDAP lookup. What we are stuck on is the following. We would like to be able
to get the hostname of the NT machine which is logging on. Someone has
suggested that we may be able to do this using a signed applet. I have no
experience with Applets at all & wondered if any one knows if this is
achievable or has accomplished anything similar? Any other ideas on how we
might do this?
Many thanks

- JTable size adjustment after addrow(), JScrollPaneHi all.
Basically I'm doing the following:
--snip--
DefaultTableModel myTableModel=
new DefaultTableModel(new String[] {"header1","header2"},0);
JTable myTable=new JTable();
myTable.setModel(myTableModel);
TableScrollPane.setViewportView(myTable);
--snap--
When I do some myTable.addrow(...)s, the table is not resizing istself
appropriately, resulting in data being "cut off" at the bottom.
Does anyone know how to correctly adjust a table's preferred size (or
whatever) after changing its contents to fit the new row count and thus
making it usable in a ScrollPane?
Many thanks in advance,

- changing Reader midstreami have what seems to be a fairly common problem, but i can't seem to find an
answer... i have a java program which opens a connection to a webpage and
seeks to read the webpage in. if the charset is defined in the header, then
no problem - i simply set up my InputStreamReader using the correct Charset
and away i go. but if the charset is defined in a META tag, then i want to
be able to recognize that.
a good example of why this is important: Yahoo! Japan uses EUC-JP encoding,
and specifies it in the header. Excite Japan uses Shift_JIS encoding, and
specifies it in the META tag.
here's some pseudocode:
URL url = new URL(webpage);
URLConnection conn = url.openConnection();
if (conn.contentType() != null)
charset = getCharset(conn.contentType()); // yay!
else
charset = ISO-8859-1; // default
InputStream = conn.getInputStream();
BufferedReader reader = new BufferedReader(new
InputStreamReader(in,charset));
while (get data from reader) {
if (data is META tag && content-type specifies a new charset) {
reader = new BufferedReader(new InputStreamReader(in,newCharset));
// this is the problem
}
}
this, unfortunately, does not seem to work. is there a better (i.e.,
standard) way to do this?
thanks!

However when you use JDBC to query the column definitions, see:
http://java.sun.com/j2se/1.4.2/docs/api/java/sql/DatabaseMetaData.html#getColumns
with code like:
Cx = DriverManager.getConnection(aJDBCP + aTblDB, aUsr, aPW);
DBMD = Cx.getMetaData();
// __
RSFlds = DBMD.getColumns(aTblDB, null, aTblNm, "%");
// __
while(RSFlds.next()){
++itFldIx;
aFldNm = RSFlds.getString(4);
// __
iFTp = RSFlds.getInt(5); // java.sql.Types
aFTpS = RSFlds.getString(6); // TYPE_NAME
iFSz = RSFlds.getInt(7); // COLUMN_SIZE
iDecDigs = RSFlds.getInt(9);
iFNull = RSFlds.getInt(11);
iOrdPos = RSFlds.getInt(17);
...
}
// __
You will for example see that for a tinyint 4 bytes are being used
and that the column type in string format, does not return the
'unsigned' type specifier. Also, apparenly MySQL uses one byte less
for 'unsigned' variables.
Which is a little fishy to me. Both 'signed' and 'unsigned' variables
should use the same storage they are just interpreted differently,
since just one bit is used for the sign.
MySQL returns the same DATA_TYPE in the form of an java.sql.Types int
and TYPE_NAME as a String for 'signed' and 'unsigned' variables
Trying to use the difference in the COLUMN_SIZE specifier does not
work for example for 'BIGINT' and 'BIGINT UNSIGNED'.
How can you tell from the Data Type Definition/specifiers which
fields are unsigned ones?
There should be a 'descriptive' way right? (Other than going the
monkey way, inserting some data, retrieving it, comparing it and
deleting the test record, with which, well . . ., should be definitely
safe)
Do you know of standard or none standard ways to do that?

Fair enough, let's consider as a warm up for the discussion that will come
once you'll show your proposal ;-)

- Add ActionListener to an Action
Okay so Action is fine for centralising event handling for multiple controls
of the same function. But I want to add a plain ActionListener for this
event. Seems reasonable. If I was just using ActionListeners I would add
as many as I like to a component. And they'd all be notified, but if I use
Action then I need to add the ActionListener to the Action, I can't.
Do I really need to get my subclassed AbstractAction to manage
ActionListeners and propagate the ActionEvent by calling
super.actionPerformed ?
Is there a better way? Other than abusing PropertyChangeListener ?

- Servlet as JMS Sender/Receiver ?
Can a Servlet act as both a JMS Message Sender and Receiver?
Clients who call on this servlet would be BLOCKING for a response.
The servlet itself upon receival of client request sends the message to
the request MQ queue. This message will be picked up by a standalone
app(JMS client), after processing would write to the response queue.
Meanwhile the servlet would be polling onto the response JMS queue with
receive(timeOutPeriod) with the appropriate msg-selector.
Is there any other approach to avoid the blocking receive. I have read
that server side polling would use lot of sys resources and block the
threads. What other feasible approach is possible?
Having an asynch imple. is a NO in this case because clients cannot
write messages to the Queue.
The appln is hosted on WebSphere5 ND.
Any feedback would be very helpful. Thanks.

As a great example of c++ portability, this doesn't even compile with
my version of g++ (mingw), so I will use cygwin to compile. gcc
version 3.4.4 (cygming special)
g++ -pipe -O3 -fomit-frame-pointer -mfpmath=sse -msse2 fasta.cpp -o

jet 0.420s 1.701s 14.602s
(note this guy uses -Xbatch flag everywhere. I have to see how that
helps anywhere. It's just slightly slower with -Xbatch flag if
anything).
HotSpot VM is faster than native Jet compiler once again? That's three
in a row. g++ is only slightly faster, not 50 or 100 times as some
think.

In following my hearts calling it leads me to tell you to say
welcome
I see some-thing that i guess allot of people do not see.
And that is a blessing from the storm.
Let me tell you a little bit about me self if i may.
You see all i have i gave up to GOD to this vary day.
For all i had is now in GOD'S hands i have nothing left but HIM.
No Car , ID , Income , House ,Wife Every-Thing is gone.
Plus i have never been happier living in faith totally.
>as i make my bed in SHEOL thou art with me .
For in Not knowing what i will be doing up until the time i do it
gives GOD all the time HE needs to work through me.
And in doing so giving HIM all the GLORY found in it as well.
The truth found in a Ethereal world we all live in
And my faith in him is growing faster and faster on a daily bases.
For HE is giving me guidance from my prayers through is SON.
To show you ; and the world.
That with out doughy HE is real.
And have that doughty cast into the Ocean for good.
Just like you see that HELL washed away.
Right from the boat you see me on in this site in-which i gave back
to
HIM
HIM who GOD.
Are Father in Heaven who it be thy name.
So to get back to what i mean ; in i see something that i feel allot
of you don't see.
and that being the blessing found in the wood laying all a muck down
south in the Gulf Coast of are Country. For Behold it is overlaid
with
Gold and silver.
Look in the Bible to see some answers to just what can happen when
you
wait on HIM for the answer

" Behold, it is overlaid with gold and silver,
Yet in it there is no breath at all.
20 " But the LORD is in His holy temple.
Let all the earth keep silence before Him."
What we do is simple we pick up all the little pieces that are laying
every were. And stock pile it for Manufacture.
say at all the Libraries to start. And just a shoe box full.
For then theo's well off or well to do people who wish to give Money
to these Paper-weight-pen-holders.
Ones lets say that are made just for these Donates in the Gluf Coast
and New Orleans area in-which were they were made our collected
at.People then who pay for them with this program could go through
its
fruition creating something of value big time for its monetary Value.
Plus everyone who helped from the people how picked it up to the
driver who drove it plus the plant.
Who made particle board out of it.
And with the scraps left over sent it then to have it then in-cased
in plex-glass and made into that paper weight pen holder thanking the
Donation given from that person who bought it and in faith allow
blessing to come from it when being seen to all who see it on there
desk.
Plus they then can write there vision like i wrote mine.
>From this blessing found in the storm and are Country's biggest
natural disaster.
Thank you GOD for this vision
