What do you think of this book: "Programming and Problem Solving with Java"

Hello Everyone:
This may be a strange post but I am wondering if anyone has read this book and what do you think of it?
Book Information
Title: Programming and Problem Solving with Java
Authors: Neell Dale, Chip Weens, Mark Headington
Publisher: Jones & Bartlett
Thanks for any comments

No believe me the book is bad! The only reason I asked is I am in a university class that uses those two books for there course. The author messed up on HelloWorld.java with 4 errors at compile time! How can anyone be that stupid since they are the ones who are supposed to be teaching me the fundamentals of Java. Anyhow I just wanted other people's thoughts about the books.
Thanks again for your input.

Mediawiki, mysql, php? problems [SOLVED]

On Sunday my Arch install that is hosted by Slicehost became unresponsive to them so they had to do an emergency reboot. After it came back up my install of mediawiki was (and still is) only returning a blank page (at least in Firefox). After some digging I found out that part of the problem was that mysqld wasn't starting so I managed to get that fixed by commenting out the lines relating to innodb and putting in skip-innodb into my.cnf. But I'm still getting a blank page.
According to Mediawiki's manual, "A blank white page indicates a PHP error which isn't being printed to the screen." They give two lines to put into LocalSettings.php to force error messages but after doing that I'm still getting a blank page. Changing display_errors in php.ini to ON didn't have any effect. When I load the wiki in Safari I get the following error: "Got java.io.EOFException (Server closed connection while sending the HTTP header.): http://some_url.com/mediawiki/index.php/Main_Page". I have no idea what this error means and googling java.io.EOFException doesn't bring up anything very helpful. My PHP Test Page indicates that PHP is up and running.
Any ideas on fixes or where I can find more clues?
[EDIT]
Mysql was definitely the root of the problems with Mediawiki. I tried nearly every suggestion listed in the forums for fixing a mysql install that wouldn't start but nothing worked. I even completely uninstalled mysql and reinstalled it but it still refused to start. I switched over to postgresql and switched mediawiki to run with that. Problem solved.

There are some other things that must be done to connect to
the database
(such as passing the usernamee, password, and host info to
mysql_connect()
and storing the connection resource), and those might be in
the include
files. I generally place all of the connection parameters in
a separate file
that is located in a folder that can't be accessed by a
browser, for
security purposes.

Error Code 16 on Mac with Newly-Installed Yosemite (a Java problem?)

Like many out there I am unable to use CS6 applications at all after an OS update to Yosemite (in my case from 10.8.5, on my 2012 iMac). I get an Error 16 message, and a Java problem error message.
I've read many posts about fixing this issue, including the Adobe gospel very specific to this problem—about changing the permissions in a couple of folders—, which I found here: https://helpx.adobe.com/x-productkb/policy-pricing/configuration-error-cs5.html I did exactly as directed and saw no change in the problem.
I also read that the Java version necessary for CS6 products to run on Yosemite is a boondoggle in itself. Java 6 is apparently necessary for CS6 products to run, but that version is insecure, and besides, it's old. Java 8 Build 31 is the current and safe version but it apparently is incompatible with none but the most recently-updated Adobe products. Several posts on Adobe's support pages suggest a hacky fix for this Java issue, which involves downloading and installing the latest Java version from Oracle, and then creating specifically-named empty folders on one's hard drive within a couple of obscure System/Library/Java folders:
http://oliverdowling.com.au/2014/03/28/java-se-8-on-mac-os-x/
https://forums.adobe.com/message/7193884
I did this too, and again saw no change in the problem.
Re-installing my CS6 suite has not worked, either. I receive the same error code message when starting up any of the applications. At this point I've been forced to go back to my previous operating system, since I am heavily reliant on CS6 to do my work each day.
I understand that many people are having this trouble after updating to Yosemite, and more than a few posts on these forums indicate this is true even for people like me who've followed Adobe's purported fix that I linked above. Has anyone in userland or at Adobe found anything lately that could help here?

uninstall cs6 and clean (Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6).
update your os, Java for OS X 2014-001
then install cs6.

Installing 9.2.0.4.0 on EL4 - Can't start netca, JAVA problem!!!!

Dear all,
Please help with my Java problem. Thanks in advance.
After successfully installed Oracle 9.2.0.4.0 on EL4, I tried to start netca but I received this error message:
[oracle@localhost bin]$ ./netca: line 138: /u01/app/oracle/product/9.2.0.4.0/JRE/bin/jre: No such file or directory
The JRE link at $ORACLE_HOME is as follows:
lrwxrwxrwx 1 oracle oinstall 21 Oct 27 17:41 JRE -> /usr/java/jre1.6.0_03
.bash_profile as follows:
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/9.2.0.4.0; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=$ORACLE_HOME/bin:$PATH; export PATH
ORACLE_OWNER=oracle; export ORACLE_OWNER
ORACLE_SID=OSIM; export ORACLE_SID
LD_LIBRARY_PATH=$ORACLE_HOME/lib; export LD_LIBRARY_PATH

CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib; export CLASSPATH
LD_ASSUME_KERNEL=2.6.9; export LD_ASSUME_KERNEL
What do you guys think my problem is?

I managed to solve this one. For more information you can search the forum with much earlier dates, as far as 2002. I'm very outdated.
In case you need the solution:
I tried using java 1.3.1 provided together with the Oracle9iR2 installation Disks instead of 1.1.8.
1. Delete the JRE link in $ORACLE_HOME
2. Relink it to 1.3.1 directory
3. create a jre symbolic link in the bin directory to the .java_wrapper
4. create another jre symbolic link in the i386/nativethreads directory to the java file
Good luck

Dr.Watson problems solved.

DR.WATSON PROBLEMS SOLVED:
System:
WLS 5.1 with SP11 running on NT4 Using OCI817_8.
Oracle 7.3.4 running on NT4.
Problems:
Dr.Watson exceptions in native code...
# An EXCEPTION_ACCESS_VIOLATION exception has been detected in native code outside
the VM.
# Program counter=0x60239689
When asking BEA and Oracle:
"Use the latest OCI available. It is backward compatible !"
What have been done to solve the problem:
Going through all SQL code (and doing some rewriting), configuring connection
pools (TestOnReserve / TestOnRelease, refresh, etc) and several other configurations...
At last, we tried to change to the OCI version matching the Oracla versions we
were connecting to (from OCI817_8 to OCI734_7).
Voila ! NO MORE DR.WATSON EXCEPTIONS !
Our conclusion:
If possible, use the OCI version that matches the Oracle version you are running
on.

Hi Abhijit
Couple of pointers which could resolve the issue:
1. Since you are using the JDBC-ODBC bridge what occurs internally is that your JDBC API through the Virtual Machine make calls into the ODBC API on your Windows system. So the Watson error that you are getting is probably an illegal access by one of the methods in the ODBC API - this is for the Diagnosis part.
2. The Solution part -
a. Should I change my JDBC-ODBC driver? Not necessarily because the problems could be with the ODBC interface implementation and changing the driver might not help.
b. Should I change my programming style? This is one thing which could really help. The problem with creating connections each time is that it takes a lot of resources to do it, So there is a performance degradation. What you could do inyour code is use a Java Bean to create the required Connection. You can also think of using a prepared statement appropriately encapsulate it since you are invoking a particular query repeatedly. In your JSP page you can retrive(create) this bean through the jsp:useBean tag with the session as the scope attribute. The <jsp:setProperty methods could also be used to set the DSN name and the driver.
Once this bean is successfully created you have an open connection.
Now for the part you have pasted - replace the create connections with getting a new Statement object which would hold your Query. At the end of the JSP just close the Statement object.
Once you are done updating the page you may transfer the control to a different JSP - Let that transfer trigger the connection close in the Java bean.
This should solve the Dr.Watson problem.
Good Luck!

Java problem after updating to mountain lion 10.8.2

sorry ... the problem solve, it seems that I had a problem with my router.

JTable displays string in wrong order : my code problem or Java problem ?

I have the following code that displays data in a JTable, most of the time it works fine, but I've realized when I have a cell with values like : "Snowboarding"+"[123456789]"
It would display it as : [Snowboarding[123456789
For a string like : "Chasing toddlers"+"<123456789>"
It would display it as : <Chasing toddlers<123456789
It not only moved the last bracket to the front, but also changed its direction from "]" to "[" and from ">" to "<"
Is there anything wrong with my code ? Or is this a Java problem ?

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* 
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* 
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* 
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* 
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* 
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* 
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

How to problem solve adf issue in the mx340 model

how to problem solve adf issue in the mx340 model

Alex,
the missing thing in your example is the fact, that if only one value is selected, the parameter has exact this value like BOSTON. If you choose more than one value, the parameter includes the *'*, so that it looks like *'BOSTON','NEW YORK'*. So you need to check in the package, if there's a *,* in the parameter or not. If yes there's more than one value, if not it's only one value or it's null.
So change your package to (you need to expand your variables)
create or replace package bip_departments_2_parameters
as
p_dep_2_param varchar2(1000);
p_loc_1_param varchar2(1000);
p_where_clause varchar2(1000);
function beforereporttrigger
return boolean;
end bip_departments_2_parameters;
create or replace package body bip_departments_2_parameters
as
function beforereporttrigger
return boolean
is
l_return boolean := true;
begin
p_where_clause := ' ';
if p_dep_2_param is not null then
if instr(p_dep_2_param,',')>0 then
p_where_clause := 'WHERE DNAME in ('||p_dep_2_param||')';
else
p_where_clause := 'WHERE DNAME = '''||p_dep_2_param||'''';
end if;
if p_loc_1_param is not null then
if instr(p_loc_1_param,',')>0 then
p_where_clause := p_where_clause || ' AND LOC IN ('||p_loc_1_param||')';
else
p_where_clause := p_where_clause || ' AND LOC = '''||p_loc_1_param||'''';
end if;
end if;
else
if p_loc_1_param is not null then
if instr(p_loc_1_param,',')>0 then
p_where_clause := p_where_clause || 'WHERE LOC in ('||p_loc_1_param||')';
else
p_where_clause := p_where_clause || 'WHERE LOC = '''||p_loc_1_param||'''';
end if;
end if;
end if;
return (l_return);
end beforereporttrigger;
end bip_departments_2_parameters;
I've written a similar example at http://www.oracle.com/global/de/community/bip/tipps/Dynamische_Queries/index.html ... but it's in german.

WiFi connection problem solved

My intel iMac and MBA had no problem but iPods 3g and 5g did. I had an old Netgear router connected and sitting next to my Airport Express. On a hunch I diconnected the Netgear and created a guest network to replace the one on the Netgear. PROBLEM SOLVED!
Evidently our iPods and boarder's iPhone had problems sorting out the signals and finding the right addresses. Moving the AE to a higher and slightly more central position also helped.

Same here on a Vodafone PocketWiFi 2.
Tried NetworkManager, wicd, wifi-menu but all have the same issue.
I recently installed Aptosid on another machine and it has the same problem... It also has kernel version 3.9.
All the live CDs I've tried work, even an Arch CD from May works, though a current install does not.
I have no problems connecting to another (wpa2 enterprise) network yet can't on this 3G modem.
I'm hoping this isn't a permanent issue and perhaps an update very soon will fix this.
It seems the only way to fix this for now is to use an old version of Linux. I'm currently running a virtual machine only for the purpose of Internet sharing, very annoying.

Bug fix for Mac book wireless - problem solved!

Aparantly there is a rather large number of folks out there who've discovered this dillema with wireless not working very well at this point on the Macbook.
Well, I can attest there is one very good solution out there for this issue. This application called Sonar Theater from www.sunray.tv includes a bug fix for the wireless connection issues with Macbook in their latest 1.5 release of Sonar Theater.
I downloaded it, put it into my start up folder and waalaa! problem solved. I've haven't any more issues with dropped wireless since - it's been running constantly for over 2 weeks now.
I haven't even attempted to touch my router configuration - don't need to.

Welcome to the better life of Macs. I am using Sonar Theater too and it's been working very well for me. In fact, I'm getting hooked on just texting a message to my Mac book to fire up user sessions now. I think if you give the Mac Book some time however, you'll find that there really is no comparison to PC's. Your life overall is going to just keep getting better as you dig in to the resources available to new Mac users.
I'm sure it seems confusing to PC users at first, but here's how to set up any application as part of your startup sequence. It really is extremely easy and simple compared to the PC world. Oh and by the way, in reality, Mac users refer to this as your login sequence. So, at login time, you can do a multitude of different things for each user account you might want to set up. Naturally, you can choose to share or not share applications and data between these user accounts on your Mac too....
Mac OS X 10.3 or later
1. Log in as the user who wishes to have a login item or as an admin user.
2. Choose System Preferences from the Apple menu.
3. Choose Accounts from the View menu.
4. Click the name of the user.
5. Click the Startup Items button
6. Click the "Add {+}" button.
The item you selected will automatically open the next time you log in.
there are several ways to get good info from the apple community on tips and tricks as well. you should just try the apple os x web site...here,
http://www.apple.com/macosx/resources/
happy mac-ing!

Java problems-locking

i have 10.6 and the latest download of java. I am trying to run Scottrader Streaming quotes and it locks up constantly/ Tech support suggest it is a java problem and i have a bad instalition of jave which i do not understand as software update installed it for me. the problem is that the java application will suddenly stop running/ any ideas? scottrade suffested reinstalling java. ig that is needed how do i unstall java?

If Java functions at all, then it is not apt to be an issue with the Java installation. There's really no such thing as a "bad installation of Java". Java will run or it will crash. Lock-ups are generally the result of application errors or communication errors (e.g., it's waiting on a responsed from a server that never comes).
You can reinstall Java using Pacifist and your restore DVD. I doubt that it will be worth your time, however.

Acrobat printing problems (solved)

Hi Folk
I'm getting on well with Arch apart from one problem, I can not print from Acrobat reader, it accepts the command and does precisely nothing, the jobs are appearing in cups but not being printed, I can print from Open Office and test print from cups but no cooperation with acrobat, anyone have any ideas? thanks
Pete

I don't know what DE are you using. In my case, I use xfce and when acroread starts with his stupidity I just change the print command to 'xfprint'. That forces acroread to redirect the print job to xfce's printing frontend, and problem solved.
Now, if you're using kde, I guess there is something named 'kdeprint', 'kprint' or similar. For gnome, I've no idea.
I hope this helps.
p.s. Sometimes, cups takes his time to print. When its taking too long I purge cups' temp files and restart the daemon.
