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:

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:

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?

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:

It works to runjava task. But my problem with runjar continues.

Hello:

I have this class:

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:

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:

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.

Hello:

In a ant buildfile, I have a property with strings separated with commas:

Now I want iterate over these tokens to execute some task. It would be like use String.split() Or use <forToken> JSTL tag. Exemple:

But I did nothing about this in Web. Comeone knows how to do this?

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,

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

Thanks,

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:

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:

Called class:

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

...


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: 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,

I need verify a exstence of attribute in JNDI (in Tomcat 3 or 4). I would like do something like this:

But I do not find anything like this in JNDI api. So I must use exception:

Does Someone know better way?

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, 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?
