Hello:

My Application use a property file, loaded to a Property class (see example). I need download this using JWS. My first attempt was use <resources>/<jar> tag:
<resources> <j2se version="1.4+"/> <jar href="lib/teste.jar" main="true"/> <jar href="configdir/teste.properties"/> <jar href="lib/commons-lang-2.0.jar"/> <property name="meuvalor" value="uga-buga-jws"/> </resources>
But it did not work. When JWS launched my application, I got this message:

Bad MIME type returned from server when accessing resource: http://localhost:8080/teste/configdir/teste.properties - null

Probably JWS try downloaded this file like a binary one.
Someone suggest me to include property file in a jar file and load this in application using ClassLoader.getResourceAsStream(). But I preferred load this like a (text) File.
So my question is how download configuration or other helper files using JWS. Does JWS download only JAR files?

Thanks,

Hello:

Ok. Add jar in class path works. My buildfile is below:
<?xml version="1.0" encoding="UTF-8"?> <project name="testant" default="build" basedir="."> <property name="src.dir" location="src" /> <property name="bin.dir" location="bin" /> <property name="lib.dir" location="lib" /> <property name="jar.dir" location="${lib.dir}" /> <property name="jar.name" value="teste.jar" /> <property name="jar.file" location="${jar.dir}/${jar.name}" /> <path id="classpath.basic"> <fileset dir="${lib.dir}"> <include name="**/*.jar" /> </fileset> </path> <path id="classpath.runjar"> <path refid="classpath.basic"/> </path> <target name="build" depends="init"> <javac destdir="${bin.dir}"> <src path="${src.dir}" /> <classpath refid="classpath.basic" /> </javac> </target> <target name="jar" depends="build" description="--> cria Jar"> <jar destfile="${jar.file}" basedir="${bin.dir}" update="true"> <manifest> <attribute name="Main-Class" value="Teste" /> <attribute name="Class-Path" value="commons-lang-2.0.jar" /> </manifest> </jar> </target> <target name="runjar" depends="jar"> <java fork="yes" jar="${jar.file}"> <classpath refid="classpath.runjar" /> </java> </target> </project>
But now I have a new doubt. If I had more than a jar file in my classpath. Would I include these files one by one in "Class-Path" attibute?

Thanks,

In your runjava target your class Teste isn't in your classpath.

Ok, I include bin directory in classpath and it works. Build.xml was modified:
<?xml version="1.0" encoding="UTF-8"?> <project name="testant" default="build" basedir="."> <property name="src.dir" location="src" /> <property name="bin.dir" location="bin" /> <property name="lib.dir" location="lib" /> <property name="jar.dir" location="." /> <property name="jar.name" value="teste.jar" /> <property name="jar.file" location="${jar.dir}/${jar.name}" /> [B] <path id="classpath.basic"> <fileset dir="${lib.dir}"> <include name="**/*.jar" /> </fileset> </path> <path id="classpath.runjava"> <path refid="classpath.basic"/> <path location="${bin.dir}"/> </path> [/B] <target name="init"> <mkdir dir="${bin.dir}" /> </target> <target name="clean"> <delete dir="${bin.dir}" /> <delete file="${jar.file}" /> </target> <target name="build" depends="init"> <javac destdir="${bin.dir}"> <src path="${src.dir}" />[B] <classpath refid="classpath.basic" />[/B] </javac> </target> <target name="jar" depends="build" description="--> cria Jar"> <jar destfile="${jar.file}" basedir="${bin.dir}" update="true"> <manifest> <attribute name="Main-Class" value="Teste" /> </manifest> </jar> </target> <target name="runjava" depends="build"> <java fork="true" dir="${bin.dir}" classname="Teste">[B] <classpath refid="classpath.runjava" />[/B] </java> </target> <target name="runjar" depends="jar"> <java fork="yes" jar="${jar.file}">[B] <classpath refid="classpath.runjar" />[/B] </java> </target> </project>
It works to runjava task. But my problem with runjar continues.

Thanks,

Hello:

I have this class:
import java.util.Date; import javax.swing.JOptionPane; import org.apache.commons.lang.ObjectUtils; public class Teste { public static void main(String[] args) { JOptionPane.showMessageDialog(null, "Now it is\n" + ObjectUtils.toString(new Date())); System.exit(0); } }
org.apache.commons.lang.ObjectUtils package comes from Jakarta Commons Lang. This source is in src directory and Commons Lang jar is in lib directory. My buildfile is in root directory and it is:
<?xml version="1.0" encoding="UTF-8"?> <project name="testant" default="build" basedir="."> <property name="src.dir" location="src"/> <property name="bin.dir" location="bin"/> <property name="lib.dir" location="lib"/> <property name="jar.dir" location="."/> <property name="jar.name" value="teste.jar"/> <property name="jar.file" location="${jar.dir}/${jar.name}"/> <path id="classpath"> <fileset dir="${lib.dir}" > <include name="**/*.jar"/> </fileset> </path> <target name="init"> <mkdir dir="${bin.dir}"/> </target> <target name="clean"> <delete dir="${bin.dir}"/> <delete file="${jar.file}"/> </target> <target name="build" depends="init"> <javac destdir="${bin.dir}"> <src path="${src.dir}"/> <classpath refid="classpath"/> </javac> </target> <target name="jar" depends="build" description="--> cria Jar"> <jar destfile="${jar.file}" basedir="${bin.dir}" update="true"> <manifest> <attribute name="Main-Class" value="Teste"/> </manifest> </jar> </target> <target name="runjava" depends="build"> <java fork="true" dir="${bin.dir}" classname="Teste" > <classpath refid="classpath"/> </java> </target> <target name="runjar" depends="jar"> <java fork="yes" jar="${jar.file}"> <classpath refid="classpath"/> </java> </target> </project>
build and jar target run OK. But when I run runjava target I get this message:

Buildfile: C:\java\eclipse\workspace\testant\build.xml
init:
build:
runjava:
[java] java.lang.NoClassDefFoundError: Teste
[java] Exception in thread "main"
[java] Java Result: 1
BUILD SUCCESSFUL
Total time: 1 second

And runjar target prints this:

Buildfile: C:\java\eclipse\workspace\testant\build.xml
init:
build:
jar:
runjar:
[java] java.lang.NoClassDefFoundError: org/apache/commons/lang/ObjectUtils
[java] at Teste.main(Unknown Source)
[java] Exception in thread "main"
[java] Java Result: 1
BUILD SUCCESSFUL
Total time: 1 second

But if I remove reference to ObjectUtils method:
import java.util.Date; import javax.swing.JOptionPane; public class Teste { public static void main(String[] args) { JOptionPane.showMessageDialog(null, "Agora S�o\n" + new Date()); System.exit(0); } }
runjar target runs correctly, but runjava target shows same message.
I it was problem of classpath configuration, I had problems with build target. So my mistake must be in other place, but I know where.

Thanks,

Hello:

Thanks to all. I have did this using javascript:
<script description="Run rimc to create RMI stubs" language="javascript" > <![CDATA[ importClass(java.io.File); // "myproject" is the project name defined in "project"'s attribute "name" var rmic = myproject.createTask("rmic"); rmic.setStubVersion("1.2"); rmic.setBase(new File(pegasus2NG.getProperty("build.dir"))); // defined in property file // "mytarget" is the target name defined in "name" attribute of "target" mytarget.addTask(rmic); var classes = myproject.getProperty("rmi.classes").split(","); // defined in property file for(var i = 0; i < classes.length; i ++) { rmic.setClassname(classes[i]); rmic.execute(); } ]]> </script>
I did not know about ant-contrib. I will look at this.

thanks

Hello:

In a ant buildfile, I have a property with strings separated with commas:
<property name="classes" value="Classe1,Classe2,Classe3"/>
Now I want iterate over these tokens to execute some task. It would be like use String.split() Or use <forToken> JSTL tag. Exemple:
<forToken items="${classes}" var="classe"> <rmic base="bin" classname="${classe}"/> </forToken>
But I did nothing about this in Web. Comeone knows how to do this?

Thank,

Hello:

I have a problem with my eclipse 3.0. When I want do Software Update (Help -> Software Updates -> Find And Install) I got this message: "Error retrieving 'feature,xml'. [error inopening zip file]". The "Install/Update" is showed anyway. If I check "Search for new features to install", prior error message is showed. I don't know what "feature.xml" it referenced, So I renamed all "feature.xml" in Eclipse directory to "--feature.xml" . But my problem persists. Someone know what does it means? I am using eclipse 3.0 in Windows 2k.

Thanks,

Hello:

I've intalled eclipse in my Win98. When I started it, does not open. It is showedd a message saying that it is not possible open it. In log file (in configuration directory) it is written this:

Did Someone see it before? What is "application id"? It happens both with SDK elcipse and RCP Eclipse.

There is no such concept as "all the classes in a package", in much the same way as there is no such concept as "all the subclasses of a class". This is because it is dynamic information.

A quick read of the spec. will reveal that you can use reflection to get all the loaded classes of a particular package.

In ClassLoader there is a protected method called getPackages(). So It is possible get all packages used by ClassLoader. But classes? Well, we back to my question.

Hello:

If have a Package object, how can I get all its classes.

Thanks,

Hello:

I have two classes: One with main() method (caller class) and other not (called class). both record log messages using java.util.loging. Log configuration is done in caller class. I want that log file have messages from caller and called classes. However in log file it is shown only caller messages.
Below, the source codes.
Caller class:
package testalog.launcher; import java.io.IOException; import java.util.Timer; import java.util.TimerTask; import java.util.logging.*; public class LogLauncher { private static final Logger log = Logger.getLogger(LogLauncher.class.getName()); private static final long PERIOD = 15000L; public static class LauncherTask extends TimerTask { public void run() { LogLauncher launcher = new LogLauncher(); launcher.execute(); } } public LogLauncher() { try { FileHandler h = new FileHandler("acao.log"); // log file name h.setFormatter(new SimpleFormatter()); // log formatter log.addHandler(h); log.setUseParentHandlers(true); } catch (SecurityException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public void execute() { Acao acao = new Acao(); log.info("Iniciando ..."); // Beginning ... acao.execute(); log.info("Terminando ..."); // Finishing ... } public static void main(String[] args) { Timer timer = new Timer(); timer.schedule(new LauncherTask(), 0, PERIOD); } }
Called class:
package testalog.launcher; import java.util.Date; import java.util.logging.Logger; public class Acao { private static final Logger log = Logger.getLogger(Acao.class.getName()); public Acao() { log.info("Criando ..."); // Making ... } public void execute() { log.info("Execute �s" + new Date()); // Execute at ... } }
In console I get this:

28/07/2004 15:57:58 testalog.launcher.Acao <init>
INFO: Criando ...
28/07/2004 15:57:58 testalog.launcher.LogLauncher execute

28/07/2004 15:58:13 testalog.launcher.LogLauncher execute
INFO: Terminando ...
...

But in log file It is showed:

28/07/2004 15:57:58 testalog.launcher.LogLauncher execute
INFO: Iniciando ...
28/07/2004 15:57:58 testalog.launcher.LogLauncher execute
INFO: Terminando ...
28/07/2004 15:58:13 testalog.launcher.LogLauncher execute
INFO: Iniciando ...
28/07/2004 15:58:13 testalog.launcher.LogLauncher execute
INFO: Terminando ...

To recapitulate: In console it is showed log messages from caller and called classes, but in log file only caller messages was written. What I need is find a way to record all log messages from called classes in log file.
Suggestions?

Thanks,

Hello:

I need verify a exstence of attribute in JNDI (in Tomcat 3 or 4). I would like do something like this:
Context ctx = new InitialContext(); if(ctx.existis("java:comp/env/ras")) { ds = (DataSource) ctx.lookup("java:comp/env/ras"); } else { ds = null; }
But I do not find anything like this in JNDI api. So I must use exception:
try { Context ctx = new InitialContext(); ds = (DataSource) ctx.lookup("java:comp/env/ras"); } catch (NoInitialContextException ex) { log.debug("No Data Source"); ds = null; }catch (NamingException e) { throw new RuntimeException(e); }
Does Someone know better way?

Thanks,

Hello:
That is the question: I don't want use card sound. So, it seems that I would need JNI to create a *.DLL or *.SO. Is there a library in C or Pascal that can do it?
Thanks,

Stephan:
Thanks, but I do not want anything relationed to Java Media or Multimedia. I want a simpler thing. I remember that in Turbo Pascal (or Turbo C) there is a function similar what I want. But I do not remember what its name and I do not find it anywhere in Internet. Does someone know?
Thanks,
