Cramming for solving a java problem

I got a problem , my java code is reffering a class method of a jar file (which comes along with installation).
But while debugging I found that it could not found that method so it is throwing the following exception
java.lang.UnsatisfiedLinkError: no Jawin in java.library.path

I hope this error will come when we refer to some native method and if it could not found that.
I kept that external jar file into classpath still the problem persists .
Can you suggest me what could be done to access native methods of a jar file from my java code
Please suggest me immediately as I have serious problem in production environment.

You need to add the directory that contains Jawin's native .so libraries to LD_LIBRARY_PATH (on Linux/UNIX) or .dll to PATH (on Windows).

Re: Help needed for easy Math & Java problems

The logic in pseudo code :
IF length <= 1
Price = Base price;//Base price = 8 in your case;
ELSE IF length <= 10
Price = Base price + (Extra Meter Price * (length - 1));
ELSE IF length <= 20
Price = (Base price + (Extra Meter Price * (length - 1))) * Discount1
ELSE
Price = (Base price + (Extra Meter Price * (length - 1))) * Discount2
RETURN Price.
Code it in Java then.
Do not use magic numbers.

Thank you for solving that USB-problem!

After last update my wireless usb-mouse now works fine. No more unplugging & plugging in after sleep-mode or completely disabling energy-saving anymore.
Thanks.

The ipad does not have a phone number.

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.

*PROBLEM SOLVED: Using "java" command in JSDK1.4.1

I had a problem before when using the java command for JSDK1.4.1
What I just realised/found was that there different situations
for using the "java" command. I will give you some tips in
case you are running in the same problem or may be to help
another person:
RUNNIN FILES (.java) THAT ARE "NOT" PART OF A PACKAGE
1)Let's say you have a "test.java" file in "C:\APP\SUB\"
2)You can compile it from iside or outside the folder that
holds the "test.java" (i.e. SUB)
3)After compiled, you can ONLY run the "test.class" file
from within the folder that holds the CLASS file i.e. "SUB"
You can not be at the "APP" folder and type:
"java SUB.test" NOR "java SUB/test"
RUNNING FILES (.JAVA) THAT ARE PART OF A PACKAGE
1)Let's say you have a "test.java" file in "C:\APP\SUB\COM\"
2)Now let's say that the fiel includes the "package SUB.COM;" line
in the code, which makes it part of a package.
COMPILING
3)If the "test.java" file does NOT use another file in the same
folder, you can compile it from where ever you want. It could
be from within inside OR outside the folder holding the file
4)If the "test.java" file DOES use another file in the same folder,
then you have to go "javac" it from any folder aoutside the
folder that is hosting (holding) the "test.java" file
EXMAPLE:
If am in folder "APP" I can do this: "javac SUB/COM/test.java"
Or if am in "SUB" I can do: "javac COM/test.java"
BUT if Im in "COM" I can NOT do: "javac test.java"
RUNNING
5)Make sure that you have produced a "test.class" file when compiling
6)Recall that the "test.java" file includes the line "package SUB.COM;"
which means that it is part of this package. and that it is stored
inside "COM"
7)You can ONLY run the "test.class" file from the FIRST folder above
the package where that the "test.class" file is forming part of
i.e from inside the "APP" folder, You CAN NOT run the file from
anywhere else but the first folder (APP) above the package (SUB.COM)
8)EXAMPLE:
To run the "test.class" I must be in: "C:\APP"
I can NOT be in "C:\" nor "C:\APP\SUB" nor "C:\APP\SUB\COM"
Then type in the command window: "java SUB.COM.test" and..
*** ESO ES TODO AMIGOS!! **** (THAT'S ALL FOLKS)
I hope this help to other people.. some factors like enviromental
variable may change what I just stated though.
In my computer runnning "Windows 2000" my variables are:
1)JAVA_HOME: C:\j2sdk1.4.1
2)path: <other paths>;C:\j2sdk1.4.1\bin;
THANK U FOR ALL THE PEOPLE WHO WERE TRYING TO HELP ME SINCE YESTERDAY
my email: [email protected]

Yeah, he did get a lot of it wrong but oh well, at least he's putting forth some effort. If you need any help alex, just send me a note. Everyone should also look into using Jakarta Ant for even your simple applications, it makes all these little directory issues go away real fast. If you need a generic build.xml file that has nice features, again, just send me a note.

Hi,
Not sure why are you getting this kind of error (which is pointing to a URL with Jpg file) while creating a journal.
Could you please bounce your server once and try..
Please let us know if the error/warning stopping you to enter a journal in GL??
We don't think profile option is a show stopper here.... We assume that you have assigned Sets of Books, MO: Operating unit & HR USer Profile option at Responsibility level correctly....

Can i download java for my ipad, the problem is i open glovis.usgs from my ipad, but i can't see the full page, cause the page need a java...help me please

Can i download java for my ipad, the problem is i open glovis.usgs from my ipad, but i can't see the full page, cause the page need a java...help me please

Nope. The iPad (and iPhone and iPod touch) cannot execute Java applets. It's a limitation in iOS from the beginning (just like lack of Flash). You will either need to use a desktop computer or access a desktop computer via RDP or VNC to access that page on iPad.mIn short: there is no native way to use a Java applet on iOS.

Java Problem solving!

Hay Guys,
Can anyone tell me about sites that offer free Java Problems and Excercises, for both begineers and advanced levels...
Thank You for you help

Can anyone tell me about sites that offer free Java Problems and Excercises,Whats wrong with this site. Spend time answering questions here.
Read and learn from the postings of others who make suggestions and post solutions.
That way you learn while helping someone else at the same time.

I wish to thank cor-el for solving the problem I expressed earlier.

Thanks to cor-el for solving the problem I had with tiny text when I opened AOL mail. Using Ctrl-0 worked perfectly.
Thanks very much.

You're welcome.

A solution for Secure Static Versioning problem in 1.5.0_10

Hi,
I have JRE 1.3.1_09 and 1.5.0_10 on my computer and I think I have solved static versioning problem.
My test computer:
- Windows XP sp2
- Internet Explorer 7 (on another computer also IE 6)
- Firefox 2.0.0.1
- JRE 1.3.1_09
- JRE 1.5.0_10
I. Solution for Internet Explorer 6 and Internet Explorer 7
1. Edit registry and add:
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Deployment\Policy
DWORD: EnableSecureStaticVersioning = 0 (Hex)
2. Restart browser if started.
3. Start web page with java applet.
II. Solution for Firefox 2.0.0.1:
1. Install 1.3 JRE in the same parent directory as 1.5 JRE.
Because default default installation path for 1.5 JRE is C:\Program Files\Java\jre1.5.0_10 you need to modify
1.3 installation path from default C:\Program Files\JavaSoft\JRE\1.3.1_09 to C:\Program Files\Java\jre1.3.1_09
After installation check out that "bin" directory is in the following path:
C:\Program Files\Java\jre1.3.1_09\bin
2. Install 1.5 JRE in default installation directory: C:\Program Files\Java\jre1.5.0_10.
After installation check out that "bin" directory is in the following path:
C:\Program Files\Java\jre1.3.1_09\bin
3. Restart browser if started.
4. Start web page with java applet.
Note: HTML page must use <object> tabs for Internet Explorer or <embed> tabs for any other browser (e.g. Firefox). You need to specify correct classid in object and/or embed tag.
P.S. If anyone would like to discuss with me send me an e-mail to [email protected], but please post question to forum and just mail me a link to forum. I will write my answer to forum.
Hope this helps,
Grofaty

I have been trying to find a solution for this issue at our organization for over 6 months. Finally, we have a work around to run multiple java versions for newer and aging java apps.

Need to solve serious security problem with Oracle Reports URL

As mentioned repeatedly on this forum, Oracle Reports allows serious security breaches that allow users to see reports that they did not generate -- it's easy to guess a legal URL by changing the getjobid parameter.
I've reviewed the JavaDocs to part of the rwrun.jar file and reviewed some of the example report plugins. This shows promise in helping to solve this security problem but critical pieces are missing.
1) The javadocs are accurate for only 10g (9.0.4) but not correct for 10g (10.1.2+), which we are currently using. I need access to the updated version of this javadoc.
2) Even with the updated version of the JavaDoc, I haven't found a class from which to inherit that would give me the opportunity to generate random jobid values, which then would effectively prevent users from guessing other jobid values, and thereby gaining access to other's reports (which in our cases, may contain sensitive information.
3) We have found that we can send the parameter=value of EXPIRATION=1 which helps protect such information, but this requires that every program which invokes a report be modified to add this parameter. It would be far better for the report server to be configured to use a java class we write that inherits from some rwrun.jar class that would by default, add the EXPIRATION=1 parameter.

Hi,
Thanks for our replies. I will ask to an administrator about this security problem, now I know it depends of a security parameter.
But I would know if it could be possible to hide the technical name of the query in the url. It could improve the security level of our reports in a first time in this way.
Thanks a lot,
JW.

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=$ORACLE_HOME/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
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
