Java compiler/debugger

i'm getting pretty sick of writing my java application notepad, saving it as "file.java" and then going to the command prompt to compile it and run it.
is there any tools out there that can make it quicker for me?

This search list tells it all. Just use the box in the upper ritht hand corner.

Run time java compiler

Last year I researched oracle spatial technology and created prototype using oracle 9i, standalone oc4j. In order to start oc4j, i had to download java 1.4.2 from sun site. everything worked fine.
Now I am expanding on the prototype on different machine but am using oracle 10g. I followed the same steps (installed 10g, oc4j, downloaded j2se 1.4.2 and installed). When I start oc4j by following command
java -jar oc4j.jar, I get
error message stating Error loading package at file:/E:/oracle_downloads/oc4j/j2ee/home/applications/admin_ejb.jar, javac.exe no
t found under F:\oracle\product\10.1.0\db_1\jre\1.4.2, please use a valid jdk or
specify the location of your java compiler in server.xml using the <java-compil
er .../> tag.
I am not sure how do I specify location of java compiler in server.xml file sysntactically. I do not not recall this step with oracle 9i.
I edited server.xml and http-wev-site.xml as per instructions in my spatial class for mapviewer application but I need help on how to enter the location of java compiler file in server.xml file.
Thank you

You cannot use the JRE java to start oc4j. Must install a complete 1.4.2 J2SDK (not JRE) then use the java binary under its bin directory to start oc4j (not the one under jre/bin directory).

How to run a java program without Java Compiler

I have a small project and I want share it with my friends but my friend'pc have not
Java compiler.
for example, I writen a application like YM, then 2cp can sent,receive messege. My cumputer run as Server, and my frien PC run as client.
How can my friend run it? or how to create an icon in dektop tu run a java program..??..
(sorry about my English but U still understand what i mean (:-:)) )

To run a program you don't need a Java compiler. Just the Java Runtime Engine. That can be downloaded from the Sun website and comes with an installer.
You could then turn your application into an executable jar file and start it somehow like jar myYM.
There is also software that packs a Java program into an executable file. I've never used that but one that comes to my mind is JexePack. It's for free if you can live with a copyright message popping up every time you start the program.

Javax.sound missing with Fedora Core 3 linux's java compiler?

I'm running Fedora core 3, and I did a complete install(selected all the packeges). I have the java compiler that FC3 installed. I can compile most things, but I seem to be missing the sound package/folder.
This leads to an error when I try to import the sound libraries.
//start code
//simple non-working example
import javax.sound.*;
class sounds
//end code
results in the error "The import javax.sound cannot be resolved"
I am trying to run a code snippet from javaAlmanac, and of course it won't work. Today, a friend of mine had the exact same problem on a windows machine using JDK 1.5.
I'm going to test this code out on a windows machine also.
Are there issues with the FC3 java compiler?
Has anyone else run into and solved this issue?
I'm considering copying the sound folder from some other Java installation, anyone try this?
Thanks,

I'm pretty new at this myself. I've also installed Fedora Core 3 on an AMD 64. When I do the same uname - a I get:
Linux localhost.localdomain 2.6.9-1.667 #1 Tue Nov 2 14:50:10 EST 2004 x86_64 x8 6_64 x86_64 GNU/Linux
Maybe you didn't install as 64 bit ?
I've also successfully installed Jave Runtime Environment. java -version gets me:
java version "1.4.2_08"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_08-b03)
Java HotSpot(TM) Client VM (build 1.4.2_08-b03, mixed mode)
I'd suggest installing 32 bit. I can't tell the difference when I run programmes that use 64 or 32 bits - it will be just as good.

Java Compiler API Status?

Does anyone know what the current status of JSR 199: Java Compiler API is?
(http://www.jcp.org/en/jsr/detail?id=199)
To me it seems the inclusion in JDK 1.5 was silently dropped. I have not found the smallest bit of information, though.

JSR199 is in suspended animation. For Tiger, we're
merely documenting the com.sun.tools.javac.Main entry
point.Hi,
where could this documentation be found?

Oracle Java Compiler 11g - JVM ERROR

Hi Jdev Team,
I have an issue to report,
Sometimes when run a project and navigate through the pages, i get the following error message:
Oracle Java Compiler 11g
Unable to create an instance of the Java Virtual Machine
Located at path:
H:\jdevstudio1111\jdk\jre\bin\client\jvm.dll
The only way to solve this is delete the settings of the Jdev and the Jdev from the PC, and install again, with the associated waste of time as consecuence. Please you can give a light to resolve this issue? Thanks
Well i correct what i just said.
The problem doesn´t fix, with the erase of the jdev program folder or settings folder in windows user docs and settings. What else i can do!?, out of ideas in here.
Regards,
Leo

Oracle java compiler

Hi everyone,
I just wanted to create a new Project Build-Script as I stumbled upon this Checkbox (for auto-generating my Script):
"use oracle java compiler for javac task"
Can anybody tell me where I find a list of features this compiler provides in comparison to my normal compiler. (I tried JDev, Google and here...)
Are there any profits with using ADF / Business Components?
Hay.

Hay,
If you are using JDev 10g - you need to use OCJ to get some of the profiling aspects; less of a reason to use OJC in 11g.

out Error in Java compilation: \s7u.log (The system cannot find the file specified)
Any suggestion appreciated.
Daniel Huang

Having not seen this before, I assume that the issue is that the command line string is too long when Javac is invoked.
Here are a few things to reduce the size of the command line:
- do not use the CLASSPATH option, but set the CLASSPATH environment variable (you can to that in a .bat file)
- do not provide the .java files but rely on the implicit make capability in both, the SQLJ translator and the Java compiler. (Note: you must mention all of the .sqlj files that your program requires, do not rely on implicit make to find all of those.)
- you can perform the -ser2class conversion as a separate step (see the SQLJ FAQ), as well as the Java compilation
- there may or may not be a facility in your operating system to increase the size of the environment (and this may or may not have an effect on the maximum command line length)
- you could try to omit the -passes option and see if that helps (that may actually be where your invocation if failing in the first place, in that it cannot write to some temporary file).
Let us know how it goes. Thanks!

Java compiler validation

I've developed a java compiler in java that will be used in a tool to teach java programming. I'd like to test the compiler with an independent set of programs.
Anyone know of a free/inexpensive compiler validation suite of programs?
Many thanks.

Hey Keith,
You may want to post this question on the jboss community forum. No idea what's going on here...

yes.
just include the correct jarfiles in your classpath.

Java Compilation

Hi ,
I want to know how the JAVAC and JAVA command works internally. And also the JVM and JDK architecture to understand the java compilation and execution process. Can anybody help me out .

Its a fun fun world of abstract syntax trees, lexical analysis, etc. etc. Your question is not Java programming related in any case and certainly not something to pose in a forum - perhaps you can find a good book on compiler theory. Its very complex material, I warn you.

Java Compilation Process and how it relates to portability

I need to know more about the java compilation process, how it achieves porability and its drawback and benifits. Can anyone help me with a link or an answer?
Help would be much appriciated!

javac, the Java compiler, is written in Java itself. It generates .class
files from your .java source files. Those .class files are loaded by the
JVM (the Java Virtual Machine) and executed. The javac compiler
itself consists of just a bunch of those .class files and the compiler
doesn't even know on what platform it is running while compiling
your .java files.
If you simply carry over the tools.jar file (and some other .jars) in which
the package com.sun.tools.javac resides to another platform where a
JVM is installed you can compile your .java files on that other platform
too. And those compiled classes will run on that platform too ;-)
kind regards,
Jos

How to specify java compiler options in JDeveloper ?

I am using JDeveloper 10.1.2. I downloaded and installed JDK 5.0.
In my "Project Properties"->"Libraries" I created a new "JDK 5.0" J2SE Version and pointed to the new JDK5.0 execuitable. So far so good.
Now I need to compile all my source code with -source=1.4 option. How do I specify java compiler option "-source=1.4" in JDeveloper ?
Thanks
Sachin

Even before compilig I am not sure that by just going to "Project Properties"->Libraries and creating a new J2SE, I now have the new compiler working with JDEveloper. How do I test this ?
