For every import ,there should be class file

suppose, i have written some servlets and complied .
Their class files will be placed in their packages.
does we need to set class path for those classes?
i think that ,those classes we are using i.e weblogic.jar or rowset.jar for them we have to set the class path.
but why do we need ,for our classes ,need to set.It will check in web-inf ->classes
please clear information

does we need to set class path for those classes?No. Because your app server will take care of that anyway.

please clear informationAll you need to do is to create a bundle (WAR, EAR) with all the JARs you need. What you're doing might not work because you're also relying on JARs you're notnecessarily supposed to use and that aren't provided to you by the app server.

PSE 10 organizer displays SAMSUNG CAMERA PICTURES title for every imported image.   How to eliminate?

PSE 10 organizer now displays SAMSUNG CAMERA PICTURES as the title for every imported image. This is very annoying.   How to I prevent PSE from assigning this attribute to the title metadata upon import?   I have thousands of photos, and going through each one to delete the title isn't really an option.   Has anyone encountered this type of behavoir?
Windows 7 pro, if that matters.

Should deployed class files execute permission should be 755?

im getting the following error
Request URI:/OA_HTML/OA.jsp
Exception:
java.lang.ClassFormatError: adb/oracle/apps/xxtra/gtl/webui/XxtraGtlInquiryCO (Illegal constant pool type)

Although there should be execute permissions on the class file, this issue is not because of file permission.
There is a JDK bug (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4165020) for applet classloader.
For us (since we are not trying to load an applet codebase), this could also be due to corrupted class file.
upload the file in binary mode , bounce server and retry.

Is it possible to define one language for every imported text? And other problems when placing text.

Problem is, that Indesign cc 2014 does not recognize language correctly. In my case it should always be slovenian (and documents like doc and docx are set to slovenian), but it set it as slovakian. I get many documents from different programs (Word, Libre Office, Open Office ...). And setting every one after placing it into document is time consuming. Word import was working great in InDesign 5.5. Now it just mixes local character formating. Also: importing docx takes too long, and when in document is some picture, it just freeze. So I must first open every doc/docx file and delete every picture/logo that is inside.
Any suggestions?

Check the language of your default Character Style. If it's set to Slovakian, change it to Slovenian with no documents open.

Class file has wrong version 51.0,should be 49.0

Dear All,
I have 2 jdk in my computer, one is 1.7 and another is 1.5. I got a eclipse from my co-worker, checkout project from svn, complied it successful. However, there is error : class file has wrong version 51.0，should be 49.0 when I run it in eclipse( this is google gwt project).
One of my colleague said I should modify one cache file under the eclipse direcotry, but he forgot the loaction of this file.
Anyone knows?

After modified this file : org.eclipse.jdt.launching.prefs under : <project folder>\.metadata\.plugins\org.eclipse.core.runtime\.settings,
this problem has been fixed.
The modification is :
add
<libraryLocations>\r\n<libraryLocation
jreJar\="D\:/Java/jdk7/jre/lib/resources.jar"
jreJavadoc\="http\://docs.oracle.com/javase/7/docs/api/"
jreSrc\="D\:/Java/jdk7/src.zip" pkgRoot\=""/>\r\n
to it.
eclipse is :
Eclipse Java EE IDE for Web Developers.
Version: Luna Release (4.4.0)
Build id: 20140612-0600
my questions are :
1. what is this file used for?
2. when use this file?
3. why I have to add these information to it by hand rather than generate these automatically when I set jdk in eclipse preference?
4. why this error occur if this file doesn't has <libraryLocations> when running project(the project compile success before running)?

InDesign "Save As" dialog box for every operation in INDB book file; updating page numbers, etc.

So I haven't used INDB files in awhile in InDesign, and today was the first time I attempted to adjust an old INDB (created originally with CS5). For every operation of adjusting the book file, such as updating page/section number or adding/removing an INDD file I get a Save As dialog box for each constiuent INDD file. This is quite annoying since the book has lots of INDDs, and I have to click through the tedious save as with each. I previously worked with INDBs in CS5, and never encountered this, there was no need to save each INDD in the book just to update the page numbers. I tried creating a new INDB in CS5.5 thinking that maybe it was because I was working from a file created with an older version of InDesign. Does anyone know if there is a way to suppress the Save As dialog? Another thing I noticed that is supremely frustrating is that this new build of InDesign doesn't default to saving the file in its original location, and I have unwittingly ended up saving files in other places, only to later realize it. I am using InDesign CS5.5 Ver. 7.5.2 on Mac OSX 10.7.3 Any help is greatly appreciated.

It will only happen once (and frankly, what you are doing is a very bad idea).
When you open the old book in CS5, you are converting to the new format. All of the legacy files also need to be converted, even if added to a new book in CS5.5, hence the Save As since ID will not overwrite the old versions until you tell it to (and that's the bad idea). I strongly recommend (though it's too late for any books you've already updated and overwritten) that you either continue to edit in the old version, or that you take the time to open each file in the original version if it's older than CS5, then export to interchange format (.inx or .idml, depending on version), open those files in CS5.5, save with new names so you don't overwrite anything, then add to a new book and proceed.
One of the reasons I recommend this seemingly time-consuming approach is that there are too many reports (another one yesterday) of some sort of problem that pops up late in the editing cycle when converting legacy files to CS5/5.5 by opening them directly and saving. This is a belt and suspenders insurance approach, and is far less labor intensive than starting over, which might end up being your other option down the road if something goes wrong.

Folders for saving imported files - "From Files or Folders"?

When I "get" photos into PSE 10 from my camera or card reader, I have the option of saving each photo to a folder named after the shot date. I can also delete the original once it has been copied to my PC. Is there a way to do the same thing for photos imported using "Get Photos > From Files or Folders"? When I use the From Files and Folders route, the file organization scheme is entirely different and I would like to use the same storage organization that applies when I "get" photos from my camera or card reader.
Thanks,
Bob

Warning !
There is a big difference between getting files from camera or card reader (this implies a copy from the camera or card reader to your computer) and getting files from files and folders (already present in your computer). In the last case there is no copy (no download), just a recording in the database of the real location of the files already in your computer.
You can delete the original in the first case : it has been transferred to your computer by the downloader module. In the second case, there is no copy and the catalog is only a list of the files and their location (paths) on your computer drive. Deleting originals will delete all.
If you want to organize your already present folders in a similar date scheme at the default option of the downloader, you'll have to move or rename existing files and folders. The only way to do this would be to do the moves and renaming from the organizer itself, not from the explorer. A lot of work, and totally useless if you use the right tools like tags, categories or albums.

How do I make a batch file if the .class file uses a foreign package?

I am trying to make an MS-DOS batch file using the bytecode file from the Java source file, called AddFields.java. This program uses the package BreezySwing; which is not standard with the JDK. I had to download it seperately. I will come back to this batch file later.
But first, in order to prove the concept, I created a Java file called Soap.java in JCreator. It is a very simple GUI program that uses the javax.swing package; which does come with the JDK. The JDK is currently stored in the following directory: C:\Program Files\Java\jdk1.6.0_07. I have the PATH environment variable set to the 'bin' folder of the JDK. I believe that it is important that this variable stay this way because C:\Program Files\Java\jdk1.6.0_07\bin is where the file 'java.exe' and 'javac.exe' are stored. Here is my batch file so far for Soap:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java Soap
pause
Before I ran this file, I compiled Soap.java in my IDE and then ran it successfully. Then I moved the .class file to the directory C:\acorn. I put NOTHING ELSE in this folder. then I told the computer where to find the file 'java.exe' which I know is needed for execution of the .class file. I put the above text in Notepad and then saved it as Soap.bat onto my desktop. When I double click on it, the command prompt comes up in a little green box for a few seconds, and then the GUI opens and says "It Works!". Now that I know the concept of batch files, I tried creating another one that used the BreezySwing package.
After I installed my JDK, I installed BreezySwing and TerminalIO which are two foreign packages that make building code much easier. I downloaded the .zip file from Lambert and Osborne called BreezySwingAndTerminalIO.zip. I extracted the files to the 'bin' folder of my JDK. Once I did this, and set the PATH environment variable to the 'bin' folder of my JDK, all BreezySwing and TerminalIO programs that I made worked. Now I wanted to make a batch file from the program AddFields.java. It is a GUI program that imports two packages, the traditional GUI javax.swing package and the foreign package BreezySwing. The user enters two numbers in two DoubleField objects and then selects one of four buttons; one for each arithmetic operation (add, subtract, multiply, or divide). Then the program displays the solution in a third DoubleField object. This program both compiles and runs successfully in JCreator. So, next I moved the .class file from the MyProjects folder that JCreator uses to C:\acorn. I put nothing else in this folder. The file Soap.class was still in there, but I did not think it would matter. Then I created the batch file:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java AddFields
pause
As you can see, it is exactly the same as the one for Soap. I made this file in Notepad and called it AddFields.bat. Upon double clicking on the file, I got this error message from command prompt:
Exception in thread "main" java.lang.NoClassDefFoundError: BreezySwing/GBFrame

Press any key to continue . . .
I know that most of this makes no sense; but that it only means that it cannot find the class BreezySwing or GBFrame (which AddFields extends). Notice, however that it does not give an error for javax.swing. If I change the "set path..." command to anything other than the 'bin' folder of my JDK, I get this error:
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .
I know this means that the computer cannot find the file 'java.exe' which I believe holds all of the java.x.y.z style packages (native packages); but not BreezySwing or any other foreign packages. Remember, I do not get this error for any of the native Java packages. I decided to compare the java.x.y.z packages with BreezySwing:
I see that all of the native packages are not actually visible in the JDK's bin folder. I think that they are all stored in one of the .exe files in there because there are no .class files in the JDK's bin folder.
However, BreezySwing is different, there is no such file called "BreezySwing.exe"; there are just about 20 .class files all with names like "GBFrame.class", and "GBActionListener.class". As a last effort, I moved all of these .class files directly into the bin folder (they were originally in a seperate folder called BreezySwingAndTerminalIO). This did nothing; even with all of the files in the same folder as java.exe.
So my question is: What do I need to do to get the BreezySwing package recognized on my computer? Is there possibly a download for a file called "BreezySwing.exe" somewhere that would be similar to "java.exe" and contain all of the BreezySwing packages?

There is a lot of detail in your posts. I won't properly quote everything you put (too laborious). Instead I'll just put your words inside quotes (").
"..there are some things about the interface that I do not like."
Like +what?+ This is not a help desk, and I would appreciate you participating in this discussion by providing details of what it is about the 'interface' of webstart that you 'do not like'. They are probably misunderstandings on your part.
"Some of the .jar files I made were so dangerously corrupt, that I had to restart my computer before I could delete them."
Corrupt?! I have never once had the Java tools produce a corrupt Jar. OTOH, the 'cannot delete' problem might relate to the JRE gaining a file lock on the archive at run-time. If the file lock persisted after ending the app., it suggests that the JRE was not properly shut down. This is a bug in the code and should be fixed. Deploying as .class files will only 'hide' the problem (from casual inspection - though the Task Manager should show the orphaned 'java' process).
"I then turned to batch files for their simple structure and portability (I managed to successfully transport a java.util containing batch file from my computer to another). This was what I did:
- I created a folder called Task
- Then I copied three things into this folder: 1. The file "java.exe" from my JDK. 2. The program's .class file (Count.class). and 3. The original batch file.
- Then I moved the folder from a removable disk to the second computer's C drive (C:\Task).
- Last, I changed the code in the batch file...:"
That is the +funniest+ thing I've heard on the forums in the last 72 hours. You say that is easy?! Some points.
- editing batch files is not scalable to 100+ machines, let alone 10000+.
- The fact that Java worked on the target machine was because it was +already installed.+ Dragging the 'java.exe' onto a Windows PC which has no Java will not magically make it 'Java enabled'.
And speaking of Java on the client machine. Webstart has in-built mechanisms to ensure that the end user has the minimum required Java version to run the app. - we can also use the [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit] on the original web page, to check for minimum Java before it puts the link to download/install the app. - if the user does not have the required Java, the script should guide them through installing it.
Those nice features in deployJava.js are available to applets and apps. launched using webstart, but they are not available for (plain) Jar's or loose class files. So if 'ensuring the user has Java' is one of the requirements for your launch, you are barking up the wrong tree by deploying loose class files.
Note also that if you abandon webstart, but have your app. set up to work from a Jar, the installation process would be similar to above (though it would not need a .bat file, or editing it). This basic strategy is one way that I provide [Appleteer (as a downloadable ZIP archive)|http://pscode.org/appleteer/#download]. Though I side-step your part 1 by putting the stuff into a Jar with the path Appleteer/ - when the user expands the ZIP, the parts of the app. are already in the Appleteer directory.
Appleteer is also provided as a webstart launched application (and as an applet). Either of those are 'easier' to use than the downloadable ZIP, but I thought I would provide it in case the end user wants to save it to disk and transport the app. to a machine with no internet connection, but with Java (why they would be testing applets on a PC with no internet connection, I am not sure - but the option is there).
"I know that .jar and .exe files are out because I always get errors and I do not like their interfaces. "
What on earth are you talking about? Once the app. is on-screen, the end user would not be able to distinguish between
1) A Jar launched using a manifest.
2) A Jar launched using webstart.
3) Loose class files.
Your fixation on .bat files sounds much like the adage that 'If the only tool you have is a hammer, every job starts to look like a nail'.
Get over them, will you? +Using .bat files is not a practical way to provide a Java app. to the end user+ (and launching an app. from a .bat looks quite crappy and 'second hand' to +this+ user).
Edit 1:
The instructions for running Appleteer as a Jar are further up the page, in the [Running Appleteer: Application|http://pscode.org/appleteer/#application] section.

How to import custom java jar/class into oracle to be used in java proc ?

Hi
I would like to know how to import custom java jar/class files into oracle to be used in java stored procedure.
I am developing a oracle pl/sql procedure to call java program. The java program will be created as procedure and will be published.
But, my question is that I do have a other external jar/class file that need to be imported into this java program.
example
raise_sal.java
import java.util.*;
import oracle.sql.*;
<<reference other java programs >>
import cmpmsgsvc.xxxx.* ;
import cmpmsgsvc.yyyy.* ;
import cmpmsgsvc.zzzz.* ;
how do I import the cmpmsgsvc jar/class file into oracle so that I don't have any
compilation errros on raise_sal.java program ??
what are the steps to import/compile and validate to do this?
thanks for your help in advance.
Thanks
rrb.

Problem is that, I have 6 jar files that are needed to be included in the main java program. And, there are more than 50+ classes, propertiers in those 6 jar files.
It might be not good idea to have all those 50+ classes in the production database.
Is there anyway that I keep all those 6 jar files in unix box (our's is oracle erp installation with oracle being installed on unix box) and just refer them in the main java program. I mean database will be loaded with main java program and it should able to refer other 6 jar files from unix.
if we create a directory and keep all jar files in there and include that directory in classpath variable, does this works? or what is other method?
Please let me know.
Thanks

How do I alter the bytes of a Class file to add calls to the methods?

If i had the bytes of a class file, and I wanted to alter the bytes that constitute each method for the class so that it included a call to the security manager, how would i do it?
1. How would I know which bytes were the opening of a method?
2. how would I know what the name of the method is?
3. How would I create bytes for something like:
   SecurityManager sm = System.getSecurityManager().checkPermission(thismeth, subject);
4. I assume that if by some miracle I can do the above, then all I have to do is call defineClass(...) in ClassLoader and send it the new bytes, right?
Thanks to all!

OK, if it will help anyone get me the answers here, I found a class on the internet that can read a class file and tell you where in the bytes a method occurs and what its name is, and how long it is. What I need now is how to convert a call into the correct manner of bytes.
For example, so I could add the bytes that would do:
   System.out.println("Added!");

Running Class file

Hello,
I am a beginner.
I got a problem which is every time I run a class file after compiling *.java. I have to type the whole path
java -classpath C: (foldername) (filename)
to run the program.
It is suppose to be no problem once I can run the command "javac" successfully. Now everytime I have to type
javac (filename)
Also the setting still got something wrong which it cannot generate the path to /Lib/tools.jar as well
Could anyone help me on this?
Thank you very much
My operating system is Window 98 SE
Here is my autoexec.bat setting:
SET PATH=c:\windows;c:\windows\COMMAND;C:\PROGRA~1\SYMANTEC\PCANYW~1
@SET CLASSPATH=C:\PROGRA~1\PHOTOD~1\ADOBEC~1
SET PATH=%PATH%;C:\PROGRA~1\COMMON~1\AUTODE~1
SET PATH=%PATH%;c:\PROGRA~1\COMMON~1\AUTODE~1
PATH C:\WINDOWS;C:\WINDOWS\COMMAND
SET PATH=%PATH%;C:\JAVA\BIN
set CLASSPATH=.:C:\JAVA\lib\tools.jar
PATH c:\windows;c:\windows\COMMAND;C:\WINDOWS/DESKTOP
SET CLASSPATH=C:\WINDOWS\COMMAND;C:\WINDOWS/DESKTOP

Your batch file overrides the value of CLASSPATH several times. Try putting the paths of everything you require into the last instance of the "SET CLASSPATH" line and then eliminate all other instances of it for purposes of readability.
By the way, this kind of question should probably not be posted in the "Java Virtual Machine" forum. No offense, but the "New to Java Technology" forum would be more appropriate.

Need a script to import the data from flat file

Hi Friends,
Any one have any scripts to import the data from flat files into oracle database(Linux OS). I have to automate the script for every 30min to check any flat files in Incoming directory process them with out user interaction.
Thanks.

# Example INIT.ORA file
# This file is provided by Oracle Corporation to help you customize
# your RDBMS installation for your site. Important system parameters
# are discussed, and example settings given.
# Some parameter settings are generic to any size installation.
# For parameters that require different values in different size
# installations, three scenarios have been provided: SMALL, MEDIUM
# and LARGE. Any parameter that needs to be tuned according to
# installation size will have three settings, each one commented
# according to installation size.
# Use the following table to approximate the SGA size needed for the
# three scenarious provided in this file:
# -------Installation/Database Size------
# SMALL MEDIUM LARGE
# Block 2K 4500K 6800K 17000K
# Size 4K 5500K 8800K 21000K
# To set up a database that multiple instances will be using, place
# all instance-specific parameters in one file, and then have all
# of these files point to a master file using the IFILE command.
# This way, when you change a public
# parameter, it will automatically change on all instances. This is
# necessary, since all instances must run with the same value for many
# parameters. For example, if you choose to use private rollback segments,
# these must be specified in different files, but since all gc_*
# parameters must be the same on all instances, they should be in one file.
# INSTRUCTIONS: Edit this file and the other INIT files it calls for
# your site, either by using the values provided here or by providing

# estimates for computer memory availability. You should adjust values upward

Central auto-reactions for individual MTEs, not entire MTE classes

Hello.
I am trying to set up central autoreactions on a Sol Man system (CEN) to monitor certain MTEs on a satellite system (soon to be many more satellite systems and other MTEs). I know that auto-reactions can be assigned to a satellite system and specific MTE class in RZ21 on CEN, but I don't want auto-reactions for every MTE in a specific class. For example, I want to monitor the percentage full for a specific file system, which has the class "FilesystemPercentageUsed", but there are many other MTEs in the parent "file systems" branch which also have the same class. I only want a central auto-reaction for the one--not all of the MTEs in that class.
Has anyone else achieved this? If so, I'd love to hear your recommendations. Any help is appreciated!
Thanks!

Hello Matthew,
central autoreaction is only possible for MTE classes.
> For example, I want to monitor the percentage full for a specific file system, which has the class "FilesystemPercentageUsed", but there are many other MTEs in the parent "file systems" branch which also have the same class. I only want a central auto-reaction for the one--not all of the MTEs in that class.
In this case: change the MTE class. As you use already agents (otherwise central autoreaction would not be possible) you can configure the agent to use MTE classes different to the default ones.
The Online documentation for the agents describes this: [Monitoring Operating System Data with CCMS Agents|http://help.sap.com/erp2005_ehp_03/helpdata/EN/2b/6dcd06dc6b084a840f209e027e39b1/frameset.htm].

Executing class files from a Java App dynamically

Hi!, Is there any way i can execute java .class files from my Java Application dynamically. I know that java uses Dynamic method Invocation. Is that true of class files generated using some other language compiled for the JVM.
In my case i would like to make a Web browser that interprets HTML and also java applets embeded in them. I would like to use the JRE of the platform execute the applets for me rather than writing the code for my Browser to interpret the class files.
Thanks in Advance.

You just need a custom class loader to bring these applets into your JVM.
http://developer.java.sun.com/developer/onlineTraining/Security/Fundamentals/magercises/URLClassLoader/index.html
Then you can use the methods of java.lang.Class to create an instance of such a class. As soon as you have it, you can just treat it as a regular Applet and invoke init(), stop() etc. appropriately.
If you want to execute anything else than conventional Applets, you might consider reflection to find out about methods implemented:

How can I hide the class file ??

Hi !
I has a question, when i write a program of Java, then use the command "javac" to compiler to class file for other people using, but the class file can be disassembled and convert to source code. How can I hide the class file and let people can not disassemble, or can not see the source code. Thinks

See these....
