Using the javac command

I'm trying to create a class with the javac command. I used notepad to write the code and saved the file as .java, but when I try to use the javac command to compile it I'm told that it can't read the file. Not sure what the problem is. Any help is appreciated. Thanks.

Notepad will try to save any file with .txt as the extension. In the Save As dialog, even if you type factorial.java, Notepad might save the file as factorial.java.txt. If you look at the file in a Windows folder, it might display as factorial.java. To find out if this is your problem, use the DIR command in a DOS console to display the actual file name. If this is the problem you can (1) put double quotes around the file name in the Save As dialog, "factorial.java" or (2) make .java a text file type for your system.

Using the "java" command in Java 1.4.1

Hello..
I don't seem to be able to run any application that should run with
the "java" command in Java 1.4.1. Everytime I use "java" I get the "java.lang.NoClassDefinitionError"
Even running this simple program doesn't work:(
package chapter10;
public class test {
public static void main(String args[]) {
System.out.println("Hello WORLD!!");
}//end class
when I run: "java chapter10/test"
I get the following message:
"Exception in thread 'main' java.lang.NoClassDefinitionError: chapter10/test"
And the sam happens to any other class when I try to run it:(
The "javac" command works fine:) but the "java" is giving me a hard time:(
I would appreciate any suggestions or answers to this problem:) THANK U

See if this explanation helps.
Assume that your programs are part of a package named divelog, which is specified by the first line in each source file: package divelog;
Also assume that this directory (C:\javaT\myWork\) is part of the CLASSPATH list of directories.
Also assume that all the source files reside in this directory structure: C:\javaT\myWork\divelog\
Then a statement to compile a source file Named Divelog.java is:
C:\JavaT\myWork\>javac divelog\Divelog.java
Explanation:
Java starts looking for classes in the directory(s) listed in the classpath. In this case, one of the directories should be: C:\JavaT\myWork\ since it contains your divelog package.
Compiling
A class can either be part of a package (ie, no package statement at the top of the class.), or not.
If the class is not part of a package: Its source file needs to be in one of the classpath directories. To compile you use the command: javac SomeFile.java, from within the classpath directory that contains the file.
The class is part of a package (this case): The source file must be in a subdirectory structure that starts in one of the classpath directories. The subdirectory structure must match the package statement.
So, you generate a directory structure C:\javaT\myWork\divelog\ which is the [classpath directory + the package subdirectory structure], and place Divelog.java in it.
Then from the classpath directory (C:\JavaT\myWork\) use the command: javac divelog\Divelog.java
This creates a file, Divelog.class in the divelog directory. (The following is where people tend to get lost.) The correct name now, as far as java is concerned, is the combination of package name and class name: divelog.Divelog (note I omit the .class)
Running
To run a class that's not part of a package: From within the classpath directory that contains the class. use the command: java SomeFile
To run a class that is part of a package: From within the classpath directory (C:\JavaT\myWork\) use the command java divelog.Divelog (Note that this is analogous to the command for a class not in a package, you just use the fully qualified name)

the problem I have since I upgraded to Mavericks version 10.9.1
The problem appears only with Mail not with other programs, not even with my browser.
When I try to zoom the text of an e-mail I received or sent , I can no longer use the keys Command + to enlarge the text, although I can reduce it with Command -.
As I have a problem with my eyes, This is a serious matter for me.
When I write an e-mail, if I select text and press Command +, it just displaces the text to the right.
Now, my husband has a USB keyboard. If he connects it to my computer, his regular Command + does not work either, but he uses the extended keyboard, then it works. Unfortunately, he needs it for a musical application which does not work with a wireless keyboard.

Firefox 3.6.4 and 3.6.6 use a process called, "plugin-container.exe" which was using up most of my CPU when I opened up multiple tabs that contained Adobe Flash files, and caused Firefox to lock up.
My solution was to use Firefox 3.5.10 which you can get from the Mozilla website at [http://www.mozilla.com/en-US/firefox/all-older.html]
I am using Adobe Flash 10.1.53.64 without any problem in this version of Firefox. Check the release notes, I believe it contains all the latest security fixes in "Firefox 3.6.4".
Hopefully, they will fix Firefox 3.6 in the next version (e.g. Firefox 3.6.7), until then you should probably use "Firefox 3.5.10".

Saving a pdf file using the print command

I'm having a problem saving a document to pdf using the print command. I'm using an old version of Adobe. it's Adobe Acrobat 6. it is giving me the following error The instruction at "0x775355b2" referenced memory at "0x775355b2". The memory could not be "read". Could someone please help me resolve this issue. Thank you.

The OS and release version of the source file's authoring application have a significant impact on use of Acrobat 6.
For example, Acrobat 8.1 is where Vista support begins.
With MS Office, Acrobat 6 PDFMaker compatiblility is only for Office 97, 2000, XP, and 2003.
Be well...

Export to PDF - Can a single report (rpt file) create multiple PDF files using the export command?

Post Author: markeyjd2
CA Forum: Exporting
Greetings forum members,
My question is, in its entirety: Can a single report (rpt file) create multiple PDF files using the export command, ideally one PDF file per DB record?
In my case; I have a Crystal Report that reads data from a DB table containing ~ 500 records. When I export the report to a PDF file, I get one PDF file, with ~ 500 pages.
What I would like to do is export the report to ~ 500 individual PDF files; One file per DB record. The file names would be based on the table's primary key.
Is this possible?

CA Forum: Exporting
Hi,
you need some lines of code, but its easy. Dependend on how to start the generation of your 500 PDFs, you can write an ASP page and start it via Web Browser, or a Windows Script and start it via scheduled job...
Here's an abstract of the ASP code I use:
First, you create a recordset (here: "rsc") which gives you the list of ID fields you want to export, then you create CrystalRuntime.Application object, then you loop through the recordset, open your report (here: "oRpt") and set login info. Then set the selectionformula, so that the report displays only the data of the current ID, e.g.:
oRpt.RecordSelectionFormula = "(" & oRpt.RecordSelectionFormula & ") AND {myTab.myVal}=" & rsc("myVal")
Then you export the report, move to the next record in recordset, and repeat the loop until recordset.EOF. Then you close recordset and connection.

Do we need a ODI agent to be running for using the startscen command

Do we need a ODI full installation(both server and client) for using the Startscen command or just the client install should be enough. And also do we need a ODI agent to be configured and running for using this StartScen command
Thanks

ODI client is an agent.
So you don't need to declare one more if not needed on your infrastructure.
But to run odistartscen you need to configure the odiparams.bat with your repository connexion.
If not it will try to connect by default to the demo repostory on HSQL.
best regards,
Brice

LR V1.2 Having problems using the find Command

Have just recently started using lightroom and so far managing most applications imported a series of photos and after import added keywords to them using the find function I cannot get images to appear. What seems to happen is that in the keyword tag and the folders any of the headings that contain the keyword become active the remainder show a zero no in number of images held in that folder but no images on screen
can anyone assist me
Peter

thanks for the reply
have switched of global filters, made sure that using the Find command have set keywords in "text box" and in the "rule box "contains". When I then enter a key word as soon as a type the first two or three letters
a message appears on the screen no "No photos in the selected keyword Tag" Also when you look at the folders which have a series of numbers indicating the photos in the directory the first number in each set turns to 0 with the exception of the folder and sub folder were the images are
So have not managed to make any progress

How do I turn off the alt scroll zoom? When I'm in Adobe photoshop and illustrator using the pen tool, alt is utilized for another short cut. I would like to use the alt command for the pen tool instead of zooming into the screen.

I tend to select things from left to right and every time I am moving in a downward right diagonal motion during lasso selection I am missing a clear view and I am tending to have a more sloppy selection. All this does is slow me down since I need to go back and hit those areas again. The big arrowhead just get's in the way. The original lasso tool with the thin line and small active point at it's lower left was far better for me.
I don't like turning the cursors to precise because I like to see the active tool icon where my cursor is and as the icon changes as I hold modifier keys down. If I am forced to get comfortable with using pricise cursors I guess I will, but man, I've never had to do this in my 15 years of photoshop use...
I would absolutely LOVE to find a way to get the old lasso icon -- without the arrowhead above it.
Is there any chance this option could be inlcuded in cursor preferences? I'd give much thanks, Adobe.

What are the advantages/disadvantages of using the Form Command over Creating a User Form in VBA?

I’m in the early stages of creating a spreadsheet that will require data entry into the worksheet. The worksheet could get to 1000s of rows, depending on the particular user.
When I refer to the ‘Form Command’ I’m referring to the option of adding a Quick Access Tool bar button by selecting ‘more commands’, ‘all commands’, ‘Form…’
My questions/concerns would be relating to ‘should I develop this spreadsheet with the Form Command or a User Form in VBA?
Concerns/Questions:
Deployment to other users
Protecting worksheet cells so the user can only add records using the form command or the user form in vba. In other words, don’t allow users to edit cells that are not within the table structure of the sheet or add rows if they’re not using the form
Data validation when entering data…
Keith
Keith Aul

Hi,
Both variants have pro's and cons. If you plan to use VBA you have to consider the deployment settings on other p.c.'s where you have to allow macro's where as a regular form doesn't have the need for that.
That said the userform gives you much more control because the form command is not saved. it is simply a temporary form which you have to setup every time. It's perfect for data entry. If you are looking for data validation the userform is the one to go
for. You also have the possibility to work on placements of the data entry.
So if you are looking for speed and simplicity then go for the form command. If it is handling control you are after I'd go for a userform.

Suddenly with version 9 and 10 i cant use the shortcut command of ctrl+shift+t to open the most recently closed tab.

Suddenly with version 9 and 10 i cant use the shortcut command of ctrl+shift+t to open the most recently closed tab. a feature used several times a day, previously. This is very Frustrating to me, i have tried looking up a tool keyconfig 20110522 and looked that it says that ctrl+shift+t is the right command, but i still cant use it WHY oh WHY?? if i could get some help figuring this out it would be so awesome, cause i love Firefox, been using it almost daily for the last 10 or so years and i don't intend to switch soon.

Hi,
Please check if this happens in [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode.] This is a temporary diagnostic session and you can exit anytime and start Firefox normally again.

Terminal does something strange when I use the 'say' command

Hello,
I use terminal frequently and have just nocticed something odd. When ever I use the 'say' command it said this:
- -iMac:~ $ say hello
objc[1281]: Object 0x7ffcc2b1ee60 of class NSRunningApplication autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
It doesn't really bother me, but I just want to make sure it is nothing serious
- Thanks

Could you describe this in more detail: did Firefox prevoiusly split the image over two pages and now it no longer does that?
Or is the problem that there are two images, and if they do not both fit on the first page, Firefox is not printing the second page?
Some page layouts may not print well when split across pages; there are some longstanding Firefox bugs. If this just started recently, those might not be relevant...
Could you give an example URL of a page that has this problem, and indicate where the cutover is between scale percentages that work and those that no longer work?

Error when importing Sample OBIEE Files using the IMPDP command

I'm trying to follow the lengthy directions to create the Sample App, and I'm on page 7 of this installation guide:
http://www.oracle.com/technetwork/middleware/bi-foundation/downloads/sampleapp107-deploymentguide-435786.pdf]description
I've successfully completed the first 3 bullets on the page and I'm at the step of using the 'impdp' command to import data from the dmp file. The customized command I'm using is as follows:
impdp sys/password@Eagle as sysdba directory=datapumpdir dumpfile=SASchemas.dmp version=11.2.0.0.0 schemas=BISAMPLE,OBIEE_NAVTEQ,BIFOD,BIBPM,DEV_ODI_REPO,ODI_STAGING LOGFILE=SASchemas_imp.log
(Note that I'm using my actual password in place of 'password')
Unfortunately, I keep getting the error: unknown command beginning "impdp sys/..." rest of line ignored'
Why is this not working? I've checked the syntax very carefully.
Thanks, John

Whoops I was running this from the SQL Prompt and not the Dos Prompt... Never mind.

Solaris won't shutdown using the init commands

I tried using the init commands to shut down the system cleanly. It ask me if I'm sure and I respond yes, but nothing ever happens. The the rc# files look fine. Any help would be greatly appreciated. I checked the /etc directory and the /sbin directory but no luck..

Hi,
Check /etc/inittab for an entry corresponding to the run-level you want to init to. If you're running Solaris 10 (earlier Solaris-es support this, too), you can still create an inittab entry for the run-levels you want to switch to, but this is doing things in 'LEGACY' mode: meaning, Sun is probably going to do away with direct manipulation of inittab and requre use of the SMF
Some useful reading/research:
man inittab and follow the references to other man pages

Using the assert command

I'm trying to use the assert command but when I try and compile my code netbeans outputs a error telling me that I'm trying to use it as a identifer. Although I'm sure I'm not.
Do I have to change any options to compile a assert command?
the code I'm using is:
count = (calories / 50) + (fat / 12) - (fiber / 5);
assert count > 0 : "Adjusted calories < 0";

I don't know how you do that in netbeans. I use Eclipse or JBuilder. There is usually some checkboxes under build cofiguration, and one of them usually says some thing like enable asserts, or enable 1.4 source compability.
