Property (config) files inside an EAR

I would like to deploy the configuration files for my application inside an EAR
file so I do not have to modify the classpath for my server (WLS 8.1 sp2).
My quesion is can I make all the property files available to all the EAR components
(WAR and JAR) by putting them somewhere in the EAR or do they need to be on the
class path?

They don't need to be in the classpath.
If you're on 8.1, then placing the properties file in the
APP-INF/classes directory would make it accessible for anything in the
EAR. I'd probably use an ApplicationLifecycleListener to read it when
the app deployed.
If you're using < 8.1, I'd use either a ServletContextListener or a
load-on-startup servlet in a "fake" webapp to read the file.
Let me know if you need more details.

Specify a property file inside a ear file

Hi guys I have this myApplication.ear file.
All the project inside the ear file are using myProperties.properties file.
I have been told that this property file has to be inside the ear file.In websphere 7.0 ,the administrator will specify a jvm classpath like /webAS/installedApps/myApplication.ear/myProperties.properties.During runtime my code will find the property file using this class path
I am using RAD 7.5 to generate the ear file.Can some one tell me how to achieve this.Basically my ear file has to be bundled with the property file.
thanks

You might get better results from a RAD forum if you a havent already figured out your issue.

Session sharing among multiple WAR files inside an EAR file

Hi all,
Is there a way where I can share my session object among multiple WAR files which are inside an EAR file?
Please suggest.

ClassNotFoundException trying to load classes in a .war file inside an .ear file

Hi. I've deployed an EJB2 enterprise app as an ear file on WebLogic 6
          without errors. The ear file contains web app and ejb components in war and
          jar files. The web component is set to be the default web app in the
          config.xml file. Everything deploys without error messages.
          My problem is that I get ClassNotFoundExceptions when I try to invoke a
          servlet (via its servlet-mapping) or do Class.forName() on any class file in
          the war file.
          I see in '.wl_temp_do_not_delete' that the ear file has been decomposed into
          the ejb jar and web war files. The war file is not 'exploded' into a
          directory structure, however (as the console.war is). Is this an error
          (should the class packages in the war file be 'exploded'?)
          I don't see a tag in the web.xml, config.xml, or application.xml that tells
          the server to explode the war file--is there one?
          Note that if I manually copy the exploded class folders into the
          '_tmp_war_myserver_myserver_<<webappname>>' directory (and not, curiously,
          into a WEB-INF/classes subdirectory of that directory), the servlets and
          other classes load correctly. Also, jsps and html files load just fine
          without exploding the war file.
          Note also that the server complains about not being able to find the
          classes, even though it reports that the decomposed war file is in the
          classpath. Is there a problem loading class files from a .war file (because
          the namespace is different, with root classes located in WEB-INF/classes
          rather than the .war file's root?)
          Also, in the application.xml file, what is the meaning of the
          <context-root></context-root> element? What should its value be? What if
          you leave it blank?
          Thanks for any help,
          Reid


Is there a way to add jar libraries to the Oracle JVM CLASSPATH? Is this the same as the system's CLASSPATH env. variable?
Thank you!
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Alex McClennan ([email protected]):
The package prefix in the code extract was correct - i.e. "oracle.aurora.jndi". A value of "oracle.aurora.jndi.*" would be incorrect.
The problem is that the context factory implementation specified (com.evermind.server.ApplicationClientInitialContextFactory
) can't be found, the mostly likely reason being that the library containing the class isn't on the classpath.

Can I place jar files inside ejb-jar.jar?

Hi,
I'm reading about the packaging rules for creating an ejb-jar.jar file, and I'm wondering whether it's possible to include a jar file (containing helper classes) inside of the ejb-jar file. A "lib" dir (for containing such helper jars) doesn't seem to be part of the ejb-jar file format.
The EJB 3 spec has this to say (Ch 20, "Enterprise JavaBeans 3.0, Final Release):
"The ejb-jar file must also contain, either by inclusion or by reference, the class files for all the classes and interfaces that each enterprise bean class and the home interfaces, component interfaces, and/or web service endpoints depend on, except Java EE and J2SE classes. This includes their superclasses and superinterfaces, dependent classes, and the classes and interfaces used as method parameters, results, and exceptions"
Now, it seems that the root of the the ejb-jar file contains all the classes (in the appropriate Java package layout). But what about including JAR files? The ejb-jar spec seems to have nothing to say about a "lib" dir that can contain jars (as a WAR file can).
Summary of questions:
1) Can an ejb-jar file contain a jar file? If so, how/where?
2) Can the ejb-jar file's META-INF/MANIFEST.MF file contain a reference to a JAR file?
I'm not considering correct design at the point... I'd just like to know if these 2 scenarios are possible.
Thank you!

Yes, I have an ear file..................
I have an EAR file; inside the EAR I have a WAR file (web module) and an EJB-jar file (EJB module).......... the EJB need some classes placed in a jar file (a helper .jar or an util .jar)...........
my question is: How can I use the classes of the .jar files in te EJB??????

Changing values in property file inside a jar in an ear

Hi,
I have an application that contains EJB. The environment values needed for initial context of the ejb is kept in a .properties file. I have created an ear of the application. Inside the ear there is a jar which contains the .properties file. I need to deploy the ear to different environments. However before deploying I need some kind of script to change the values in the .properties file inside the jar in the ear.
Can anyone provide some help/pointers about how can I achieve it (Using ANT/WLST)

WLST does not have any capability to update a JAR.
WLS 10.3 (still in tech preview) has the ability to override properties
files inside the jar with an external properties file. This would allow you
to deploy the same ear to different environments, and then only deploy a
different properties file in the plan directory.

Unable to load classes from jar files inside APP-INF/lib in EAR.

Weblogic version: 10.3.3
Platform: Linux x86-64 bit
We deployed an ear packaged with all the common library jars inside APP-INF/lib. Deployment was successful.
for some reason, it is always giving ClassNotFoundException for the classes inside the jars. This does not happen
in 10.3.2 version of weblogic.
We tried to add them to domain/lib directory (instead of APP-INF/lib) but still it is not able to resolve the classes.
Any pointers would be appreciated.

try using prefer-web-inf-classes in the weblogic.xml file in your WAR file
or using prefer-application-packages in the weblogic-application.xml file in your EAR.

Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ?

Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ? Please help me as its urgent.THanks for your help in advance.

Hi Jay,
SSIS can only recognize the absolute path of a XML Configuration file, the relative path is not supported. Furthermore, if the XML Configuration file is already generated, we can use the Environment variable package configuration type instead so that
SSIS runtime automatically looks for the configuration file from the path defined in the environment variable. This is convenient when we need to deploy a package to different environment. We only need to define the environment variable for package configurations
once on each server, and then the variable can be used by all the packages on this server.

Java files from a EAR file and from inner (inside EAR)

I want to read all Java files from a EAR file and from inner (inside EAR) EAR or WAR file with out unpacking.
suppose "Demo.ear" contaions the following files:
abc.java
programs / a.java
programs / b.java
src / index.java
src / com / myFolder / main.java
src.war
and suppose "src.war" again contains some java files inside differenet folders.
The main problem is that i can read all java files from "Demo.ear" but unable to reading from "src.war" b'coz my program is using JarFile class constructor which needs a archive file path, So only top level archive having the path but not the inner archives.
So, pls help me out to this problems
Thanks in advance

Firstly Sorry to writing long letter. but i was unable to express my problem.
see my code==============================
JarFile jarFile = new JarFile("Demo.ear");
Enumeration e=jarFile.entries();
while (e.hasMoreElements())
JarEntry entry=(JarEntry)e.nextElement();
if (entry.getName().endsWith(".war"))
// Then what Next to do...........
===========================================
you have mentioned "theFile" , What is this?...............
InputStream in = theFile.getInputStream(theEntryOfTheWAR);
This line is not a compatible type casting in Java..........
ZipOutputStream theWar = new ZipInputStream(in);

Using Custom Config Files with WinForms

I have created a new .config file for my application called "MyConfigFile.config" but I do not know how to reference, read or update it. Should I treat it as any other generic XML file?
Rob E.

The configuration file should be in the same directory as the application. The name of the configuration file should have the same name as the application with .config at the end. For example, an application called Watcher.exe should have
a configuration file called Watcher.exe.config.
To access the appSettings values from inside the program, use the AppSetting property of the ConfigurationSettings class.
string title = System.Configuration.ConfigurationSettings.AppSettings["Title"];
Two things should be kept in mind when accessing appSettings from the configuration file.One, the AppSetting could be null. Two, the AppSetting property always returns a string.When getting values from the configuration file, the code needs
to handle these situations.
One way to approach this is as follows:
int AppSetValueMax = 0;
if (ConfigurationSettings.AppSettings[key] != null)
try
AppSetValueMax = Convert.ToInt32(ConfigurationSettings.AppSettings["Max"]);
catch(Exception e)
//Exception Handling

Referencing a jar inside an ear

Hi,
I have a program where I need to get a reference to a jar inside an ear
file. For example, I have this variable set:
$WL_HOME/config/mydomain/applications/test.ear and I want to set a variable
for a jar inside this ear.
Does anyone know the best way to do that?
Thanks

When you say "set a variable", do you mean read an XML or properties file
and modify it and write it back?
It is relatively simple using the java.util.zip / java.util.jar packages.
Editing XML is a little harder; I would suggest relying on something like
JDOM or the libs from The Mind Electric.

Startup class not found if included in a jar inside the ear

I have written a startup class, i have packed it in a jar file(along with some
other classes). This jar is then packed in side an ear file.(This way i get one
single distribution file). I have added the startup class in the config.xml using
weblogic console.But at start up weblogic is unable to find the class. How to
tell weblogic about the location of the class(classpath) which is inside the ear
file. Error i get is as follows

Shirish:
Classes that are scoped in the application are only visible within the
application, not to the system classloader.
If you want to have startup classses scoped inside an EAR then you need to
use Application lifecycle listeners to actually activate these startup
classes. Application lifecycle listeners are a replacement for startup
classes.
You can check out an example of this in 8.1:
$BEA_HOME/weblogic81/samples/server/examples/src/examples/splitdir/helloWorl
dEar
Docs for it are:
$BEA_HOME\weblogic81\samples\server\examples\src\examples\splitdir\helloWorl
dEar\javadoc\index.html
Check out:
$BEA_HOME\weblogic81\samples\server\examples\src\examples\splitdir\helloWorl
dEar\META-INF\weblogic-applcation.xml
<weblogic-application>
<listener>
<listener-class>examples.splitdir.hello.startup.ApplicationStartup</listener
-class>
</listener>
</weblogic-application>
and
$BEA_HOME\weblogic81\samples\server\examples\src\examples\splitdir\helloWorl
dEar
/appStartup/examples/splitdir/hello/startup/ApplicationStartup.java
Now if you have a "startup class" that needs to be accessible for the entire
Server for a set of applications, I suggest just writing a single EAR with a
dummy web-app (I think you may need a dummy module) and an applicaiton
lifecycle listener, and have this EAR deploy before any other apps.
Cheers

Jars files inside atglib folder

HI Guys
I am creating ear file in atg by using ant script ,inside ear file i found atglib files with some jar files different files
from where it is picking those jar files inside atglib folder
please give me clear picture on this

HI David,
Will it follow config path layering while build the ear file ?
or do we need to provide explicitly each module to build?
in my application i didnot find some ootb modules in build script but inside ear file those modules jar files are i am able to see
how it is possible ? is it because of config path layering?
