Compiling all possible java files

Hi,
I have a project in which not all files/packages compiles but a set of packages compiles always.
Say set of classes which might not compile as 'A' and set of classes which will always compile as 'B'
On frequent basis i need to get update. And I am only concerned about set 'B' but when i compiles my project using ant
compilation fails as 'A' compilation fails and because of that it doesn't go further to compile 'B'.
So how to get eclipse like functionality to compile all possible files?
what i have is
================================
<javac debug="${debug}" deprecation="${deprication}"
               optimize="${optimize}" destdir="${build.home}/WEB-INF/classes"
               listfiles="${listfiles}" target="${jdk.compliance}"
               verbose="${verbose}" srcdir="${src.home}"
               memoryMaximumSize="512M" fork="true"
               source="${src.compliance}">
               <classpath refid="compile.path"/>
               <include name="**/*.java"/>
               <exclude name="HBM/**"/>
               <compilerarg value="-Xlint:unchecked"/>
===================================
I do not wish to write all the classes specifically that compiles in ant script.
Thanks in Advance

Try with failonerror option in your javac.
        <javac debug="${debug}" deprecation="${deprication}" optimize="${optimize}" destdir="${build.home}/WEB-INF/classes" listfiles="${listfiles}" target="${jdk.compliance}" verbose="${verbose}" srcdir="${src.home}" memoryMaximumSize="512M" fork="true" source="${src.compliance}" {color:#0000ff}*failonerror="false"*{color}>
            <classpath refid="compile.path" />
            <include name="*/.java" />
            <exclude name="HBM/**" />
            <compilerarg value="-Xlint:unchecked" />Regards,

How to compile dunamically genrated java files through java program?

Hi, I have a requirement where i generate java files from WSDL dynamically using wsdl2java jaxbri. I need to compile these files dynamically on the fly and jar it. Everything should happen through java program. Bcos everything is dynamic here, no information is known (like dir, file names ...) until the runtime. Everything is user fed.
the directories may contain other directories with java files. its recursive
i tried com.sun.tools.javac.Main.. but either its not scaling to my needs or i donno how to wok with this.
is there any option to compile the java files as they are created thru JAXBRI (wsdl2java)?
any help is appreciated..
-s

my requirement is :
i create java files from wsdl2java (axis).. i need to compile all the java files.. directories with in the directories (recursive)...
as bcos the the java files have inter-dependencies they have to be compiled as a bunch something like (java *.java). I donno how to do this in javac.Main tool
Once all these files are compiled i need to create a jar out of them
Any help is appreciated!

How to compile and run java files on a mac using command line?

can someone tell me or link me to some article on how to compile and run java files from command line on a mac? I have mac OS X leopard

What do you mean by "where to put them" ? What do you want to put anywhere ?
Have you read Peter's comment in brackets ? Perhaps you have a classpath problem ?

Is it possible to compile & run other java files from one file

hi friends,
i need to run 2,3 java sourse files(first.java,second.java etc) from one file.i tried the Runtime.getRunTime().exec( cmd) but here cmd must be a executable file
what is need is to compile and run the files (first.java,second.java) from one other source file
pls. help me in this matter,
with warm regards,
Vishal

Sure:public class Test {
   public static void main(String[] args) {
      try {
         Runtime r = Runtime.getRuntime();
         r.exec("javac Test2.java");
      } catch (Exception e) {
public class Test2 {
   public static void main(String[] args) {
      System.out.println("Hello World!");
}Note that Test and Test2 are in two seperate files.

Compiling / Running a Java file in JSP

Hi,
ok, I have a jsp page, which we will call page 1. Once I go to that page, I all I want it to do is compile a certain file.java, and then run the file.java. The user doesn't actually know that this is going on in the background. Page 1 automatically redirects the user to page 2 (also a jsp page).
The java program that I created (that was previously compiled and ran) creates a special javascript file. After running the file.java in page #1, the java file creates a javascript file that will be used in page 2 to display a tree node (group of information).
so, right now, I'm trying to figure out how to write the jsp code that will tell how to compile and run a java file. I was thinking about using javabeans before, but I think you HAVE to actually display the contents of the java file into the jsp (I think). Anyhow, thanks for the help!

sorry about being ambiguous before. What I mean by
running a java file was that I already created a java
file. I don't want to hava my java statements inside
the jsp file. I just want the jsp file have a command
in it that would call a java file, tell the java file
to compile and run. All the jsp file would do
(hopefully) is just give commands for a seperate java
file to compile and run. Thanks again for any help!Ok, so this other java file has some entry-point method, like main(), right? So call it...
<%
YourJavaClass.main(appropriateArgumentsGoHere);
%>
or better yet, it's an object you can use:
<%
YourJavaClass x = new YourJavaClass();
x.callSomeMethodHere(withAppropriateArgumentsHere);
x.callAnotherMethodMaybe();
%>
You don't need the jsp file to "compile" this java file, you'd already have compiled it beforehand, and it's class bytecode needs to be in your classpath (on the server side) of course.

Where do I find all the Java files?

First, let me say that I know very little about Java. I updated to "Java for Mac OSX 10.4 Release 6" using Software Update. The size of the Java update file is supposed to be 80.7 MB. Although I cannot identify any possible Java related problems, other than slow loading of some web pages, I am curious as to where Java related files of anywhere near this size are located on my computer. All I see is a Java application file of 1.6 MB, which is actually smaller than before the update (3.2 MB Rel 5), and a few KBs in user>caches>java and system>library. The file dates are all correct for the update and the receipt file is present. How can I be sure that I got all of the update and where are all the Megabytes? Thanks in advance for any help. RG.

The files are scattered through the system.
e.g. /System/Library/Java
/System/Library/Frameworks/Java* (whole bunch of sub-folders here)
/System/Library/PrivateFrameworks/Java* (ditto)
and a bunch more in the hidden folders under /usr, for example.
Not sure if this requires Developer Tools, but in Terminal:
lsbom /Library/Receipts/JavaForMacOSX10.4Release6.pkg/Contents/Archive.bom
will give a list of all the files installed/updated by the package.

Error in compilation satge of java files

Hi all
Whenever i m trying to compile java files i m getting this error .I have no idea how to go about fixing this issue. Can any one help me out with this.
Error occurred during initialization of VM
Could not reserve enough space for object heap

Well i could go ahead and solve the issue by bringing down the memory allocation at the minimum and maximum level during the compilation stage.
I got the tip from the forum itself where a similar problem had been reported and there this tip was provided.
Earlier in my case i was allocating 1GB of memory for compilation but due to some issue that much space was not being detected on the server. When i pruned that down to 512mb the compilation went ahead without any trouble.
Thanks kelly for geting in involved in geting to know the issue .

Where are all the .java files????

I placed a few of Oracle's demo JAR and fmb/fmx files on my server to test a couple of things, and they are working fine. (I moved them over to the server by copying the JAR file off my local machine and pasting then into the forms90/java folder on my server. Then I copy and pasted the fmx and fmb files over and created a [this_demo] profile for each one I was using. I also added the .jar to the formsweb.cfg)
Anyways.....
I would like to look at the actual code for one of these demos, but can't find the .java file anywhere. It's not in the JAR file. All that is in the JAR file is META-INF and oracle/forms/demos/enhancedItems2/.class(es) files.
I also downloaded sun's juggling duke JAR file(s) -juggler.jar and methodtracer.jar. I created a test form and got Duke to juggle just fine, but I would like to take a look at the .java code. Where should that be???
Thanks in advance

An error occured when trying to open the file for reading. Filename: ".\jad\tmp\MOLine.java"
Current Working Directory: C:\Program Files\Cavaj Java Decompiler\
System error message: The system cannot find the file specified.
C++ exception: ios: failbit setDo you get the same error if you use a directory name which has no space in name?
Question is, when I am trying to decompile MOLine.class to produce MOLine.java, why is it looking for MOLine.java?Most probably because you cannot decompile the class file (I believe if it was possible, Oracle would have provided the java file).
Thanks,
Hussein

Error: code too large for try statement, when compiling a big java file.

Hi,
I have a big java file ( around 16000 lines). When compiling it, I got following error message:
MyMain.java:15233: code too large for try statement
} catch ( Throwable t ) {
In MyMain.java, I just repeat following statements about 1000 times.
try {
if ( year >= 2002 ) {
System.out.println( "year: Evaluation version is not valid" );
} else {
System.out.println( "year: Evaluation version is still valid" );
} catch ( Throwable t ) {
if ( year >= 2002 ) {
System.out.println( "year: Evaluation version is not valid" );
} else {
System.out.println( "year: Evaluation version is still valid" );
I tried 1.3 and 1.4 javac compiler, there was some error.
How to make compiler to compile this code?

How to make compiler to compile this code?
You don't. Each method has an absolute limit on the number of byte codes. You have reached that limit. The limit is part of the specification and JVMs will refuse to run classes that exceed the limit. So even if you could compile it, it wouldn't run.
It is quite common for code generators to generate large monolithic blocks of code. Presumably this is how you got to this spot. Modify the code generator to break it into smaller blocks.
If you did it manually then you did it wrong. And you will have to manually break it into smaller blocks. (And re-examine your design since it is probably wrong.)

Compiling a single .java file

Hi,
is it possible to compile a single java class without having to rebuild the complete
application ? If this is not a feature is it going to be available in SP3 ?
Thanks
Mark

Just put your java classes in a Java project under your application and
then compile only that project.

I have spent hours scratching my head but don?t have a clue. I was wondering if you have any idea as why I might be getting these errors.
Thank you for your time.

Hello, did you read the answers?
You have to put j2ee.jar or servlet-api.jar in your classpath. Those JAR files are included in the Java EE package somewhere. Remove the QTJava.zip junk from the classpath.
If you don't know what the classpath is and how to set it, read this:
Setting the class path
How Classes are Found
And I'll repeat what the others say: if you are very new to Java, then Java EE will probably be way over your head. First learn the language and the standard API. If you understand that well, start with Java EE. Or do you already know what servlets are, and that you need a servlet container to run them, and how to deploy them etc.?

Deleted the app in the dock that compiles all your open files and fans them out as icons. What is it and how do I get it back?

When I bought my macbook pro, I deleted the app in the dock that complies all your open files together. When you click on the app it fans all the icons out. What is that app called and how do I find it again/get it back??
Thanks!

okay... got that...but before I deleted it, it would "fan" all my open web pages, or open PDF files. So they were in a little folder as opposed to lined up beside my trash bin?
make any sense?

add C:\Tomcat\webapps\examples\WEB-INF\classes to your classpath.
You can do this through the control panel or by:
set CLASSPATH=%CLASSPATH%;C:\Tomcat\webapps\examples\WEB-INF\classes

How to compile Java files using Ant in Eclipse

Hi All ,
I would like to compile all Java files using Ant in Eclipse.Since am very new to Ant and Eclipse can someone help me to create a build.xml file and let me know how to compile all the java files.
For ex , I have placed my java files inside the path C:\HEC\Terab.Initially the Terab folder holds 7 jar files which i had decompiled using JD compiler and placed the unzipped 7 folders (which contains the java files ).Now i have imported the HEC project into Eclipse using New ->Project ->Java Project.after importig it throwed me an error saying missing jar files.again i copied the jar files and placed inside Terab folder with other 7 folder.
Now How i can compile the java files and convert in to class files.Then after compiling the files i will again need to jar all the 7 folder.
Please tell me the steps i need to follow.How to write an build.xml file ? where i should keep it ? only one build.xml file is enough or should i write 7 build.xml file for each folder ? Please help me out...
Thanks & Regards

Compiling java files in DOS window

Hi,
I have been writin a small Client Server Application. I am attempting to use java packages in order to put certain class files into particular directories, and then import the packages when needed.
So far, i have started my 1st attempt at a very small application just to send / receive messages. My problem is however, that i can compile all the java files into specific directories & packages no problem, but when i try to compile the java files which make use of these classes, i keep getting the same error.
OK, i will try to simplify,
My Server program (called MyServer.java) uses 2 classes (called ProcessTransaction, and NumberValidator), I have compiled the generated class files from ProcessTransaction.java and NumberValidator.java files into a DIR called C:\JavaForm\serverstuff. i.e. my server program imports the package "serverstuff,*;" The problem is that when i try to compile my server program i get the error message:
"cannot access ProcessTransaction
bad class file: c:\JavaForm\ProcessTransaction.java
file does not contain class ProcessTransaction
Please remove or make sure it appears in the correct subdirectory of classpath"
I am using the command:
javac -classpath c:\JavaForm c:\JavaForm\MyServer.java to compile the server file
All the java and class files are stored in the C:\JavaForm folder
I dont understand why the ProcessTransaction call cannot be accessed because it is most definitely in the compiled java file!!!
Any help would be much appreciated!!!
Cheers
Iain

it's OK, i figured out that to compile the Server program successfully, you have to remove all the other java files from the DIR which the Server.java files exists, or else there is a conflict!!!! I dont know why, but that's what you have to do!!!!
