How to compile and package my EJB application

Hi,
I just ran the sample programs from the Sun J2EE tutorial. Seems to work fine. I used the ant utility to compile all the programs and the J2EE Deployment Wizard to package and deploy everything. Now how do I compile and deploy a sample EJB program that I have written ?
I am using the following platforms:
1: JBuilder 3.0 : IDE (for writing the source code)
2: JDK 1.4.0_01
3: J2SDK EE 1.3.1 (EJB/Appln server)
How do I make ant recognize my program and compile it... i guess the deployment procedure would still be the same.
Can somebody please help me out on this ??
Thanks
prasanna

Hi,
Thanks for your prompt reply. I tried that out.. I have a directory called "customer" under which I have my interfaces,bean implementation class and the J2EE application client.
ANT_HOME is set to : the directory where ant is installed
JAVA_HOME is set to : the directory where JDK is installed
J2EE_HOME is set to : the directory where J2EE server is installed
and PATH : includes the bin directories of JDK, ant and J2SDK EE
These are the paths I had to set when I ran the J2EE tutorial programs. It worked fine.
Now when I say : ant myprogram I get an error saying:
BUILD FAILED
Target "myprogram" does not exist in this project
How do I add my program also to the project so that ant can recognize it ?
Also if there is any other way you can suggest to compile and package my application it would be great...
Thanks
prasanna

How to compile and deploy an ejb into Sun ONE app.server 7.0

I am new to Sun ONE application server. I Have .java files and deployment descriptor files with me. How should proceed. When i tried to use asant it is saying that build.xml not found. I copied build.xml from some other directory to the current directory. Then it is saying that common.xml not found. Please help.
Regards,
Nagaraju.

Hi,
The build.xml file should be in a directory from where
you are running the asant command.
To resolve the common.xml file not found error,
open your build.xml and check from which location the common.xml file is incuded.
In the sample application it is four directories above
the directory where build.xml is located.
You can copy the common.xml in the current directory and then change the following in your build.xml
<!ENTITY include SYSTEM "../../../../common.xml">
to <!ENTITY include SYSTEM "common.xml">
Hope this helps.
Get back in case you have more issues

How to compile and run package programs in Java

Hi,
I want to know how to compile and run the package programs in Java using -d. instead of creating the package folder manually.
eg:
package Test;
class test1
public void disp()
//Any code;
I want to compile this without creating the folder ' Test ' manually. that is if we use -d with javac the Test folder will be created automatically. I need the format of -d
could anyone please help me.
Thanks in Advance ,

How to compile and creat JAR with native function

Hi there,
I wrote some native function for J2ME. But it seems like using J2ME wireless Toolkits, we can not compile native function. Is it right?
Is anyone knowing how to compile and make JAR with J2MEWTK or command line?
Thanks,
Merry Christmas!!

[zack327],
JNI like or native interfaces APIs is not supported in the CLDC/MID Profile 1.0 specification. If you have J2ME code that includes JNI code, the J2MEWTK tool will not compile successfully for you.
To package the compiled code to a MIDlet suite .jar file, use the 'Package' command in the J2MEWTK toolkit. It is found on the top menu bar 'Project' option as item on the dropdown list.
To package the MIDlets into a MIDlet suite .jar file from the command line, you can execute the usual jar file command:
jar cf MyMIDletSuite.jar Midlet.class
You will also need to create a MIDlet .jad Application Descriptor file as well.

How to compile and run a .java file from another java program

hello,
can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?

Well a smarter way of implementing this is by using a solution provided by Java Itself.
If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)
http://java.sun.com/javase/6/docs/api/javax/tools/package-summary.html
How do i do that ??
Check out the below articles which would help you of how to do that
http://www.ibm.com/developerworks/java/library/j-jcomp/index.html
http://www.javabeat.net/javabeat/java6/articles/java_6_0_compiler_api_1.php
http://books.google.com/books?id=WVbpv8SQpkEC&pg=PA155&lpg=PA155&dq=%22javax+tools%22+compiling+java+file&source=web&ots=XOt0siYe-f&sig=HH27ovuwvJgklIf8omTykUmy-eM
Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.
Hope that might help :)

How to compile a package with classess

Hi,
Can any one tell me , how to compile a package ?
Actually, i have three classes under the package named as linklist.
i am unable to compile the classes under this package ? its always raising errors. saying that the package does not exist.
Can any one tell me, why it is like this ?
thanks in advance

Hi,
Can any one tell me , how to compile a package ?I'll try.
Actually, i have three classes under the package named
as linklist. Okay, so you have the package statement at the top of each class, right?
And the 3 classes reside in a folder named linklist?
Okay, if you do, while in the folder above linklist, do:
javac linklist/*.java (using the appropriate slash)
Did it work?

How to compile and register a Java CFX tag with multiple class files?

All-
If this is the wrong forum for CFX questions, please let me
know.
I need to determine how to compile and register a Java CFX
tag that contains multiple class files. One class file implements
the CustomTag interface and the other class files implement various
supporting classes. All of the documentation that I have found
talks about using a single class file. I am assuming that a JAR
file will be involved, but I am not sure of the specifics.
Thanks in advance for your help.
-Josh

Yes, it will involve a jar. Use your java IDE (eclipse,
etcetera ..) to create a jar containing all of the classes. Check
your ide's documentation for how to create jar files. After you
have created the jar, place the jar in the CF class path so CF will
recognize it. For example the {cf_root}/WEB-INF/lib directory. CF
must be restarted before it will detect the new jar. After
restarting CF, register the CFX tag in the ColdFusion Administrator
using the name of the class that implements the CustomTag
interface.
Though it is worth noting you can also instantiate java
classes directly from ColdFusion (ie without using a CFX
tag).

How to compile and execute lex,yac,c and java programs

its the 3rd day on my New MacBook pro..
as i just migrated from windows to mac i love to work on this..
The main problem is i DON't know .......
how to compile and execute
1) lex and yac programs
2) c program
3) java program
so please help me
THIS is the error i got   a1.l is a program
i got the same error when i used gcc
$ lex a1.l
$ cc lex.yy.c
Undefined symbols:
"_yywrap", referenced from:
      _yylex in cc8QDQjW.o
      _input in cc8QDQjW.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

Is the problem that you don't know how to compile and execute these programs on a Mac, or just that you don't know how to compile and execute them?
Mac OS X is really just a version of BSD Unix, as far as programs like like bison, flex and gcc are concerned...and even when Apple specific versions are provided in the Developer Tools, there are symlinks in the usual places in the Unix file hierarchy.
For problems with lex and yacc, I suggest you start with their own references, for example, here.
Or you could just use %option noyywrap, if you only have one file to scan.
Or you could link to libfl.a using -lfl and use the default version from that library.
But you really should (as Keith Barkley was subtly hinting at) learn how these tools work and why they work that way.

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 ?

How to compile all package body using sqlplus ?

hi all,
How to compile all package body using sqlplus ?
Please help.
Amy

dbms_utility.compile_schema will compile all the invalid objects in a schema, including the invalid package bodies. If you only want to compile the invalid package bodies, you could write your own dynamic SQL stored procedure to do that using the user_source view, but that's a lot more effort for a very minimal benefit.

How to compile and publish after modified a .java file?

Hello,
I am a newbie to Business Object. I am now working on a server that installed BusinessObjects Enterprise, to develop and run BO reports. I need to edit some java codes of the InfowView. I found that there are some .java, .class, .jar files under the installed folder. I know that it is a struts framework and I can find which .java file to edit, but I don't know how to compile and publish the codes. Is it necessary to install any development tool to do it?
Regards,
Philip

Since you are using CSV, you can read a line at a time and then use String.split() on it. One you have it split, you upload to your DB using JDBC or if your in the MS world and cannot get a JDBC driver, then use the JDBC/ODBC bridge.
