J2me can load a .class file (using classLoader)?

Hi everybody,
I am developing a J2ME application that can load a .class file on a PDA.
Recently, I have found that the java.lang.CLASSLOADER is not defined on the J2ME. So, there is no way to use it.
I am asking if there is any way to load a .class file from another one on a PDA or mobile phone.
Thanks for your time and interest,

Use the class Class, that have a forName() method.

Can load image from file using LabVIEW and display on IMAQ graph?

I dont have IMAQ Vision for LabVIEW on my computer. Is it possible to load image file and display on an IMAQ graph?
Thanks!

Hey werwr,
In response to: "I dont have IMAQ Vision for LabVIEW on my computer. Is it possible to load image file and display on an IMAQ graph?"
As of right now, in order to read an image from file, you actually do need the IMAQ Vision software. The IMAQ driver without the Vision VI's will allow you to collect images from a framegrabber, and it will allow you to save those images to file. But the function that allows you to read an image from file does require the Vision VI's. Once you have the VI to read images from a file, you will be able to display the image on an IMAQ "Graph" or otherwise known as an Image Display.
I hope this helps. Please let me know if you have any further questions.
Thanks,

How to load a .class file dynamically?

Hello World ;)
Does anyone know, how I can create an object of a class, that was compiled during the runtime?
The facts:
- The user puts a grammar in. Saved to file. ANTLR generates Scanner and Parser (Java Code .java)
- I compile these file, so XYScanner.class and XYParser.class are available.
- Now I want to create an object of XYScanner (the classnames are not fixed, but I know the filename). I tried to call the constructor of XYScanner (using reflection) but nothing works and now I am really despaired!
Isn't there any way to instantiate the class in a way like
Class c = Class.forName("/home/mark/XYScanner");
c scan = new c("input.txt");
The normal call would be:
XYLexer lex = new XYLexer(new ANTLRFileStream("input.txt"));The problem using reflection is now that the parameter is a ANTLRFileStream, not only an Integer, as in this example shown:
Class cls = Class.forName("method2");
Class partypes[] = new Class[2];
partypes[0] = Integer.TYPE;
partypes[1] = Integer.TYPE;
Method meth = cls.getMethod("add", partypes);
method2 methobj = new method2();
Object arglist[] = new Object[2];
arglist[0] = new Integer(37);
arglist[1] = new Integer(47);
Object retobj = meth.invoke(methobj, arglist);
Integer retval = (Integer)retobj;
System.out.println(retval.intValue());Has anyone an idea? Thanks for each comment in advance!!!

Dump all of your class files into a directory.
Use the File class to list all files and iterateover
the files.NastyNot really, when you are dynamically creating code, I would expect the output to be centralized, not spread out all over the place.
>
Use a URLClassloader to load the URL that isobtained
for each file with file.toURI().toURL()(file.toURL()
is depricated in 1.6)Wrong, the URL you give it must be that of the
directory, not the class file.No, I did this quite recently, you can give it a specific class file to load.
>
Load all of the classes in this directory, thatway
any anonymous classes are loaded as well.Anonymous classes automatically loaded when the real
one isIt can't load it if it doesn't know where the code is. Since you haven't used a URL classloader to load once class file at a time, you would never encounter this. But if you loaded a class file that had an anonymous classfile it needed, would it know where to look for it?
>
From this point you should be able to just get a
class with Class.forName(name)No. Class.forName uses the classloader of the class
it's called in, which will be the system classloader.
It won't find classes loaded by a URLClassLoader.got me there.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. The Guest login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Dreamweaver can't open .class files

Using:
Dreamweaver CS4 Version 10 Build 4117
on Microsoft Vista Home Premium Service Pack 2
I'm trying to edit Menalto PHP Gallery files via Dreamweaver. Some of Gallery's core php module files use the .class file extension. I want the following extensions to be treated as PHP files in Dreamewaver.
phtml, class, cpt
I added these extensions to the following files.
C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS4\configuration\DocumentTypes\MMDocumentTypes.xml
C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS4\configuration\Extensions.txt
C:\Users\Me\AppData\Roaming\Adobe\Dreamweaver CS4\en_US\Configuration\DocumentTypes\MMDocumentTypes.xml
C:\Users\Me\AppData\Roaming\Adobe\Dreamweaver CS4\en_US\Configuration\Extensions.txt
I set Vista to use Dreamweaver as the default program for opening .class files.
I have restarted the computer.
I can open up phtml and cpt files just fine. However, when I try and open .class files, I get the error:
Dreamweaver can't open .class files
Please choose an HTML, XML, or other compatible file
I used Dreamweaver to create a new file in the Dreamweaver file pannel. I called the new file test.class and opened it up in notepad. Dreamweaver is successfully pre-populating the test.class file with the default PHP template.
So Dreamweaver is creating the test.class file using the default PHP template, but it still can't open .class files in Dreamweaver.
I think this might be a reserved extension or something. Anyone else had a similar problem?

Hey, I gave up myself. While I still use Dreamweaver for layout (HTML, images) work and for synching my website via SFTP, I don't code PHP in it anymore. Dreamweaver really isn't a PHP development IDE. So, I do all my PHP work in something called NetBeans. It is less user friendly but once you set it up... my goodness... is it great for coding PHP. So Dreamweaver for visual stuff and HTML stuff. NetBeans for PHP app development. That's my suggestion.

Can I open raw files using photoshop elements

Can I open raw files using photoshop elements

Yes, depending on the Camera Model and version of PSE.
All camera makers like to make slight changes to the RAW format for their new models. Adobe then take a few months to produce a camera RAW plug-in to process the new format.
Give you PSE version and camera model and we could be more help.

Issue while loading a csv file using sql*loader...

Hi,
I am loading a csv file using sql*loader.
On the number columns where there is data populated in them, decimal number/integers, the row errors out on the error -
ORA-01722: invalid number
I tried checking the value picking from the excel,
and found the chr(13),chr(32),chr(10) values characters on the value.
ex: select length('0.21') from dual is giving a value of 7.
When i checked each character as
select ascii(substr('0.21',5,1) from dual is returning a value 9...etc.
I tried the following command....
"to_number(trim(replace(replace(replace(replace(:std_cost_price_scala,chr(9),''),chr(32),''),chr(13),''),chr(10),'')))",
to remove all the non-number special characters. But still facing the error.
Please let me know, any solution for this error.
Thanks in advance.

Unable to load/play sound files using SoundEngine_LoadEffect

Hi All,
I am able to load/play sound files using SoundEngine_LoadBackgroundMusicTrack but unable to load/play sound files using SoundEngine_LoadEffect on iPhone Simulator. I am using the SoundEngine.h/cpp from Crash Landing. Oddly enough sound effects load and play succesffully when i start the app with 'Start with Performance Tool'. Does anyone know what is actually going on.
Also i would like to know what is the difference between playing sound files using these two methods. What are the restrictions on individual sound file types for each method.
Thanks

I was able to load/run the sound effects after using Simulator - iPhoneOS 2.1 in the Active Target/Build drop down on Xcode toolbar. Both Active SDK, and Active Executable should be 2.1 in order to play the sound effects.

Can't read text file using UTL_FILE

Hi All,
how can I read notepad file using UTL_FILE package.I have specified the UTL_FILE_DIR in the init.ora file.My objective is to when a button is clicked, the contents of the file will display in a text item.Here is my code written in WHEN_BUTTON_PRESSED trigger.
DECLARE
     file_handle UTL_FILE.FILE_TYPE;
data_line Varchar2(100);
BEGIN
     file_handle := UTL_FILE.FOPEN('E:\vimal','abc.txt','R');
          message('directory created');
     UTL_FILE.GET_LINE(file_handle, data_line);
     :block2.t1 := data_line;
     UTL_FILE.FCLOSE(file_handle);
END;

Why don't you use text_io? Don't forget that UTL_FILE is reading directories from the database point of view. The E drive for the database is a different E then on your client pc. I presume your database is on a different computer. Are you getting any errors?

How to Load a class file base on .class file name???

Hi,
Can anyone help me?
1) Based on filename (d:\temp\bla.class), I want to load this bla.class and get the actual package of this class.
example:
package something.temp;
public class bla
I want to load the file base on filename and get the package of the class. Is it possible ?
Thank you.

Hi nikki96,
It will not work. I will get java.lang.NoClassDefFoundError eventhough I extends classloader to use the findClass(String filename);

import java.util.jar.Attributes;
import java.util.jar.Manifest;
import sun.misc.Resource;
import sun.misc.URLClassPath;
public class MyURLClassLoader extends ClassLoader
String host;
int port;
public Class findClass(String name)
               try
     byte[] b = loadClassData(name);
     return defineClass(name, b, 0, b.length);
               } catch(Exception e)
                    e.printStackTrace();
               return null;

Problem: The class file is not in the proper package (d:\temp\bla.class) where the proper package is d:\something\temp\bla.class.
Objective: I just want to base on the bla.class (no matter where is it located), then get the package of the classfile (bla.class) like example something.temp.
Simple as that but I don't know how to do :(.

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:

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.

WebLogic looking for class file using the wrong case

During my ant build, I precompile my JSPs using weblogic.jspc. All of the jars and wars are packaged into an ear and deployed to WebLogic 8.1 on Linux. When I access one of our normal screens, everything is good. Things go wrong when I try to access one of our help screens. We have a base help file that includes another file based on the screen code passed to it. The screen code is used in combination with a HashMap to look up the correct JSP to include. This part goes fine. But when the JSP is included, I get the following error. The best I can figure is that the class file is in mixed case (i.e., SampleHelp00.jsp and SampleHelp00.class), but Weblogic is looking for samplehelp00.class.
I'm not even where I should begin looking to solve this. Anyone have any ideas?

Ignore the part about precompiled JSPs being ignored on my development server. Turns out I had a stale cache. I cleared that out and now it recognizes the files.
The problem with that, is now I'm getting an Error 500 when I try to access the page.

I passed the -keepGenerated flag to the precompile task in my Ant build so I could look at the line it's choking on, but it's not very helpful. I'm stuck. I can set up the build so it doesn't precompile the JSPs, but then the QA team wouldn't like me very much.

Struts ,can i create .class file

i am created actionform java file can i create .class for that or directly can i place it anywhere .sir plese help me on struts .how can i deploy my application in tomcat .

You are not very specific in your question. You are rquesting for help in Struts and you are also saying that you need help in Tomcat! What is it that you really want? When you load, run or use any application, its always the .class files that are picked up by the server.
Please be more clear on what you want.

How to Load 2 library files using System.loadLibrary in one .java file!!!

Hello,
Someone please help me. What I am trying to do is load two .DLL files in my program. Program works fine when I
do the following way i.e. I have two .java files and in each I am loading one .DLL file. But I don't want to have
two .java files I want to load both the .DLL files in one program.
**************** Example.java **********
import java.io.*;
import java.util.*;
public class Example
public native int A(String in);
static
System.loadLibrary( "API2" );
public static void main( String args[])
     Ex ex = new Ex();
     int r;
     r = ex.A("TEST");
public Example()
*****************Ex.java*****************
public class exsysml
public native int A(String in);
public exsysml()
System.loadLibrary("API3");
The above way works. But I need only one .java file to load both the .DLL files. i.e.
import java.io.*;
import java.util.*;
public class Example
public native int A(String in);
static
System.loadLibrary( "API2" );
System.loadLibrary( "API3" );
public static void main( String args[])
     Example ex = new Example();
     int r;
     r = ex.A("TEST");
public Example()
but when I do this way it doesn't work and I get a UnSatisfiedLinkage Error at ex.A("TEST"). While doing the top way it works.
How can I fix this to just have one .java file and load both the library files as done in the bottom program but doing this program doesn't work. Any help is appreciated.
Thanks!

what I figured out so far is that we can only load one library file in a single class and define all the native methods present in that library in the class where we are loading it. Means we can't load multiple library files in a single class. It's just my thought else if someone provides a better solution. I may be wrong so that's why I need your help.
Thanks

J2me can load a .class file (using classLoader)?
