Getting generated class files using the compiler api??

I am writing a compiler/IDE for java, and i use the new JavaCompiler API
(javax.tools.JavaCompiler)
i want to ask, is it possible to get the generated class file(compiled file) names??
can anyone help me with this, read at the documentation and i have no idea which one is used to do such thing..
Or is it impossible??
Thanks, please guide me on this..

don't.

yes, probably (after all, other tools can do it). Don't ask me how though, I've never had a need to.

no. Someone else reading the documentation for you won't help you any. Read it yourself, you might learn something.

Problems while uploading files using the FileReference API

I've built an image uploader module in Flex using the FileReference API and PHP.
While this works perfect for images upto 1 MB, What I'm noticing is that for images greater that 1 MB even after the Event.COMPLETE has triggered, the file hasn't yet been uploaded into the folder.. its only after a couple of seconds or minutes after the Event.COMPLETE, that the image actually shows up in the FTP folder. Morever I also noticed that for such files the DataEvent.UPLOAD_COMPLETE_DATA that we are using to get feedback from PHP never gets called.
I thought it would be related to the PHP script getting timed out... but the PHP script does get executed and the images do show up in the folder but thats way after the Event.Complete has been triggered and more importantly DataEvent.UPLOAD_COMPLETE_DATA doesnt get called.
Everything seems to work fine as long as the file size is under 1 MB
Did others too face similar problems and any ideas on how to fix it?
Thanks in advance

I don't believe there is, as the browse button renders out as an html input type file component, and this has no ability to get native file size from the client. The only way to do it is to check the file size server side, but that kind of defeats the purpose to some extent, as the file is required to be uploaded before the file size can be checked.
There is no way to do this on the client short of using a third party client side component - ie. java, flash or some other active component that gets file system level access.

Avoid *$1.class files after the compilation

Hi
i made an applet called ChatClientApplet.java ... As a result from the Compilation, I receive the classes
ChatClientApplet.class
ChatClientApplet$1.class
ChatClientApplet$2.class
I'd like to avoid these $ files or to choose a different character... How can i do that?
Thank's

Don't use inner classes. If you use inner classes you always get classes with a $ inside it.
Use outer classes to avoid this naming.

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.

Two class files with $ on compile

Hello friends, I have a simple java program, that consists of two classes, coded in the the same java file.
One of hte classes extends Thread.
When I compile the source file, I get one class file for the base class, and two for the other one - ClassName.class and ClassName$1.class.
Why is the second one created?

The ClassName$1.class is a class file for an anonymous inner class. You create them with code likebutton.addActionListener(new ActionListener() {
actionPerformed(ActionEvent ae) {
System.out.println("button was pressed");
});This particular example is from the GUI world where event listeners are commonly created using anonymous inner classes. There's a separate file for it just because there's always exactly one class file for each class.

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.

Than how can i get java class by using it's class file?

Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.

get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.

2. Created New project
3. Imported the page .xml file
4. Added new .java file by extending the controller class
5. Added code in the .java file.
6. Ran the .xml file
As I copied all the folders from Unix box, the page was opened.
But My question was where can I see the .class file the extended controller. It's a .java file. How to compile and get the .class file for this .java file. If I get this .class file, I can go to the page and click the personlize page. and change the Controller name to the new path by ftp ing the new class to the cust.oracle.apps.pos.changeorder.webiui.
Please let me know how to create the .class file.
Thanks,
HP

All are Java files are stored in JDEV_INSTALL_DIR:\jdevhome\jdev\myprojects\
In your case the path java would be
JDEV_INSTALL_DIR:\jdevhome\jdev\ myprojects \cust\oracle\apps\pos\changeorder\webui\
AND
Once you compile the java file in Jdeveloper, Class files get generated @ below path
In your case the path of class would be
JDEV_INSTALL_DIR:\jdevhome\jdev\ myclasses \cust\oracle\apps\pos\changeorder\webui\

Generating PDF file using FOP API in Web Dynpro

Hi experts,
I would like to generate PDF files from a WebDynpro application without using Adobe Interactive forms.
I think that I can export context data to XML stream and then apply XSLT transformation to produce XSLFO format and then pass it to xlfo processor i.e FOP to generate the PDF file.
Has someone already try this way of generating PDF files?
Is it a good way of processing ?
Thanks in advance.
Thomas.

hi Thomas,
You can make use of the iText API to create pdf documents through webdynpro.
For this you'll have to download the Itext api jar file.
Right click your webdynpro project include this jar file using the 'add external jar files'.Now you'll be able to make use of this api in your webdynpro project.

The above link will help you in using iText API.
hope this one helps you.

Hi, 80 % of my itunes files are located on a 3tb external drives; the remainder on a 4TB drive as I ran pout of space. ALL my files are on copied on to the 4TB drive . How do I get iTunes just to use the files on the 4tb drive so I can use the 3tb for other purposes THX .

Select the desired location in preferences, then consolidate the media files to it.

Why do I get error -17500 when calling a batch file using the call executable step type?

I am calling a batch file using the call executable step type. If the path to the batch file contains a space I get error -17500 and a message stating there was an error in "Post". For example the path to the batch file is "c:\TestWin\Test Files\...\Program.bat" When I run this I get the above mentioned error, however if I change my directory structure so the path is now "c:\TestWin\TestFiles\...\Program.bat" it runs fine. I use the browse feature to find my batch file so it is not me typing in a path incorrectly. I have removed the batch file and I get a different error stating that it couldn't find the file so it appears that for my error it can find the file but can't run it. I am
sure that this has something to do with the fact that batch files are written in DOS but really don't want to resort to changing my directory structure on all my test stations. Is there any way to fix this problem so I can leave a space in my path?

It appears I have figured it out. This was on another computer so I was unaware of how they used their computer. I like you got it to work in the temp directory and in fact got the program.bat file to work as long as I put it under the temp directory, but when I switched out to my TestWin directory it wouldn't work, so I removed everything from the directory except the batch file it self and it work. What I found out after adding files in one at a time is that the person had a file called "Test" with no file extension in there "c:\TestWin\" directory. Removing this file made it work. Putting the file back broke it. So it appeares that when teststand was running it followed the path saw a space and attempted to grab the "Test" file instead of bro
wsing into the "Test Files" directory. If you create a file in your temp directory called "temp" with no file extension you will see the same problem. Thank you for your help.
