Annotations: package-info.java

In Eclipse IDE I do the next thing:
@MyAnnotation
package annotations;
@interface MyAnnotation {
}And Eclipse tells me that Package annotations must be in file package-info.java. In Java Language Specification I didn't find something about file package-info.java. Where I can read something about it?
What is the syntax of the file package-info.java. Maybe you have an example?

Problem with "package-info.java" using EJB 3.0 and OC4J

Hi all.
I already posted this question on JDeveloper forum, but didn't get any answer,
so I'll try posting here.
Anyway, I'm new both to JDeveloper and J2EE,
so I'm trying out examples for EJB 3.0, and I got stuck at "Use Security Annotations with EJB 3.0"
(http://www.oracle.com/technology/tech/java/oc4j/ejb3/howtos-ejb3/howtoejb30security/doc/how-to-ejb30-security-ejb.html).
Example code is working perfectly, if one builds it using Ant, but I'm importing all examples into JDeveloper (or at least I'm trying to :))
JDeveloper can't build file "package-info.java" containing following code:
@javax.annotation.security.SecurityRoles(roleNames={"superuser", "user"})
package oracle.ejb30;I'm getting following output in "Compiler - Log" window:
Error(2,1): 'class', 'interface', or 'enum' expected.
Help much appreciated...
platform used:
Windows XP SP2
JDeveloper Studio (Version 10.1.3, Build 3412)
JDK 1.5_06
OC4J 10.1.3 developer preview 4 (standalone version)

Since you're using EJBs, you can use JTA and can skip the getTransaction() calls. If you want to use getTransaction().begin() and commit(), then make sure that your EntityManager is resource-local. The configuration for this is in persistence.xml. Set a transaction-type of RESOURCE_LOCAL rather than JTA.

Creating package-info.java in Netbeans

I'm a little frustrated that Netbeans won't even let you create a 'package-info.java' file because of its naming rules. Is there any way to get around this?

I don't know NetBeans very well, so don't know of any workaround for the naming.
You can just name the file "package.html" and it will do the same thing. The drawback is that it won't allow for package annotations -- it can still have javadoc tags, though.

XML without namespace and prefix, modified package-info.java, JAX-WS option

Hello
I have created a consumer business service which will be called from JDEdwards EOne, pulls data from database and send it to Fusion Middleware.
SO, I have created proxy using JAX-WS option. And suggested in oracle doc, I created proxy outside OMW and then copied it to my project. XML payload is getting generated without namespace and prefix. After some research, I modified package-info.java. Now, I am able to send the payload and if test it locally from Jdeveloper and take xml output using marshaller I can see it has namespace and prefix as well. BUt, when I run this from server it does not have namespace and prefix.
Please help.
Thanks
TK

Just to clerify,
The common complex types are StatusInfo, IdcProperty and IdcPropertyList. I ahve 3 more WSDL's with the exact same entires for those 3.

Checkstyle warning: Missing package-info.java file

Hi,
I'm getting a checkstyle warning for a simple class which looks like:
package tools.interprocess;
* Class for testing RMI.
* @author spinth
public final class RMITest {
     * Private constructor.
    private RMITest() {
     * Main method.
     * @param args User arguments
    public static void main(final String[] args) {
}The warning message says: Missing package-info.java file
I really couldn't figure out what this means and how I can fix it. Do I have to add something to the source tree?
I'm using Eclipse for development and Eclipse-cs as my checkstyle plug-in.
Thanks.
Edited by: spinth on Apr 15, 2010 12:37 PM

If you don't want that warning then simply turn it of.
A package-info.java file is there mostly to attach JavaDoc to the package itself.
If you don't need/want that, then the checkstyle warning is useless. Checkstyle (and similar tools) are meant to be tweaked to your needs and not used blindly.

Package info in javadoc

hi folks,
Can any one tell me how to get Package info in the Java Doc??
ie how to include comment in source code so as to get the Package
info in the javadoc ??
ex
package hiall;
* @param args
public class Hello {
} will print only the class info

Why we can not import a user defined package as an ordinary java package that is
java.swing.*;
we have to explicitly menction that class name inorder to import that specified class that is like
giri.addints;
Here giri is my own package and addints is class..........
it is not going to work if import as
import giri.*;
with regards...

How browse through the sun.* package in java

in java we have some packages starting with sun.java..... how to read these packages info.

Well unless you find urself a java class decompiler you cant see the source code but if you open the rt.jar file (found in the lib folder of your jre installation) in winzip or winrar you can see all the classes and their packages.

Which jar contains this ( com.bea.control.annotations ) package?.

Hi All,

Ok, after updating your original post and asking this question I understand what you are actually trying to do. The "local package database" generally refers to /var/lib/pacman/local, not /var/lib/pacman/sync, which is why it was unclear.
fakeroot pacman -Syb /tmp/tmpdb -i pcre
should do what you want, but be very careful never to install anything using that temporary database. Take a look at the checkupgrades script to see how it does things if you want to do more than just check remote package info.

How to query package info from the server repo instead of local DB?

Greetings!
Is there an option in pacman to query the package info ( like -Si ) from the server repo instead of the local package database? Or maybe some additional program is needed for this?
Update: Maybe this can be done by downloading a fresh copy of package DB with -Sy, but how to specify a custom package DB file? Is this accomplished with --dbpath option? Say
pacman -Sy --dbpath /tmp/tmpdb

How can I get the working directory of a project from an Annotation Processor in Java

I am writing an annotation processor in Java and in this annotation processor I want to be able to find a file in the Project hierarchy of the project on which I am using this annotation processor. Through the annotation I can pass in the path of the file I am searching for relative to the project root but i cannot retrieve the project's working directory.
Let's say that the processor is MyCustomProcessor and I am using it on the project MyProject. I want to be able to access(read) a file (a properties file) from the project structure of MyProject from the "process" method of MyCustomProcessor.
I have read this link Eclipse - Annotation processor, get project path but when I use their solution I get a null returned from the StandardJavaFileManager.getLocation(StandardLocation.SOURCE_PATH) call.
Some more details regarding the implementation:
MyAnnotationProcessor:
@SupportedAnnotationTypes(value = {"MyAnnotation" })
@SupportedSourceVersion(RELEASE_6)
public class MyCustomProcessor extends AbstractProcessor {
@Override public boolean process(final Set<? extends TypeElement> annotations, final RoundEnvironment roundEnv) {
for (final Element element : roundEnv.getElementsAnnotatedWith(MyAnnotation.class)) {

More details about the testing and development environment: Eclipse Kepler, JRE 1.7.
If you need more details just ask.

There is an identical post with an answer located at this link.
