Include my jars in a ear

Hi, i'm using servicegen ant tag to create an ear from my webservice.
Everything is ok, but i don't know how to include into the ear file the other
jar i use?.
If i put this jars in the wls classpath, my webservice works fine, but i want
to put the jars into the ear and just deploy it.
I'm using jdk 1.3.1, WLS 7.0
Thanks.

Libraries (.jar, .zip) in ear file.

Hi !
Sorry if someone asked this before.
I have a package (.jar) which would like to be shared by both ejb and war
component, I put them in the ear/lib/, and add an entry in the manifest
file. Somehow I couldn't access those package after deployed in iPlanet, nor
seeing them being extracted to any directories. Do I have to put 2 copies in
each of them in iPlanet ? Or there's any other way to work around this ?
Thanks,
Brandon

Hi,
I haven't tried out this, please try to include this .jar file in one
of the path where the path in application server points to. This might
help. You can find the application server's classpath in
Software/iPlanet->Application Server->6.0->Java->Classpath.

Invoking JAR within an EAR

I am having trouble invoking my project which is packaged in a jar and the jar is then packaged in an ear file.
I need to deploy this big ear file onto an AIX server. No single jar file can be deployed onto the server so I have no option but to include my batch project into the ear file, however, when I try to invoke my main within this jar (within the ear), the class can't be found! Can anyone help me with this? Thanks!

oh also I forgot to mention that I am invoking my program via shell script.
My script invokes the main function, so my first problem is not being able to 'see' that main function in my ear.I did, however, defined my ear file inside the classpath and used the classpath option when calling my programs. Thanks!

How to share dependant jars across rars & ears / avoid classcast exceptions

<b>How can one share dependant jars between a ear application and a resource adapter and avoid getting a ClassCastException? </b>
<P>
In some appservers(such as Oracle) the resource adapter is the parent of your ear classloader, so a single instance multiple classloader problem doesn't occur. But in some appservers such as BEA Weblogic this isn't the case. Not sure why BEA decided to make resource adapter class loader seperate and not the parent of ear loader...
<P>
If I bundle the resource adapter specific classes in the corresponding module archive file, I will get a class cast exception, becos I will have a <i>single instance and multiple class loader situation</i> (assuming resource adapters uses its own classloader).
<P>
Second question related to the above: Web logic documentation recommends that we bundle the common files in APP-INF direcotory for embedded resource adapter apps. If I start bundling the resource adapter in an ear file, for every ear app we will have a rar bundled. What about the JNDI names? won't you have to rename the resource adapter differently for each ear so that there is no jndi name clash? Doesn't this defeat the purpose of having one common connector for all apps?
<P>
Here is a detailed description of what I want:
Let say you have a ear file. Let's say there is a common.jar shared between your ear application (say the ejb module uses it), and your resource adapter.
<P>
In the case of Oracle's OC4J I can see there won't be any problem of having this common.jar part of the resource adapter(RA). When the RA class loader loads the rar, it makes sure the common.jar files are accessible in the chain of all class loaders it is a parent of. So, the ear loader, ejb loader etc...will have visibility -> hence no class cast exception.
<p>
But what do clients do when they want to have their ear deployable across multiple appservers not just oc4j. BEA recently changed their class loader structure...their resource loader is no longer parent of the ear, so the ejb app in the ear doesn't have visibility into common.jar packaged with rar. So, the only solution was to bundle the common.jar file with the ear. But this causes problems, because we can have a situation where certain object instances (that are not serialized or copied) can be shared across class loaders. This ends up in the single instance multiple class loader situation->hence classcastexception.
<p>
The only solution I found was to make the common.jar file a shared library. That way only one copy of the class files are there for both the rar and the ear and its visibility is there not only for rar but for ear since it is loaded by the system class loader or shared library class loader (if ther eis one such).
<P>
Please convey best practise recommendation.

How to access a jar file in EAR file?

I have a EAR file which contains EJB.jar file and util.jar file. Outside of EAR, I mean in client side, I need to reference util.jar file. How can I access it?
EAR structure is
|--+META-INF/
|--|---application.xml
|--|---manifest.mf
|--EJB.jar
|--|---+MEAT-INF/
|--|---|--- deployment descriptors...
|--|---|--- manifest.mf
|--|--- EJB classes
|--Util.jar
Util.jar must be executed in server side. If I just add Util.jar in client program's classpath, when client program is executed, serverside Util.jar is executed? Or what else I should do in the client program to reference server-side Util.jar?

Excellent question. I don't see any client-jar in your EAR file structure. So I am assuming you are writing a separate client application which will talk to the ejbs deployed as part of this EAR. You need to do the following:
Write another EAR file with the following structure:
ear:
META-INF/application.xml
util.jar
client.jar
client.jar should have a META-INF/MANIFEST.MF and that should contain Class-Path:util.jar and value for Main-Class attribute.
Now deploy this new ear to your application server and execute it using Application Client Container that comes with your app server.
If you don't want to write another EAR file, then bundle th client.jar in your original EAR file.
Points to note are:
you have to repackage util.jar again inside this ear file.
For portability reason, you should use Class-Path manifest entry in client.jar. Refer to http://java.sun.com/j2ee/verified/packaging.html and J2EE platform spec section #8.2.
Hope this helps,

How to Create a jar war or ear--Probelms in deploying

I have the following dir structure. I am using Struts 1.1 and weblogic 7.0

1> Do I need to create a ear file since i want both the ejb (under service folder) and war as reusable components. Whenever we have a EJB component do we always need to have an EAR file??
2> Whats the best way to create the jar, war or ear file. I am facing great difficulty in deploying the war.Do we need to set any classpath before we create the war and jar files except for the deployment descriptors.I have created the ejb descriptors correctly through ejbc.
3>I have kept struts.jar,log4j.jar under lib folder. However when i create the ear and try to deploy it under weblogic it deploys the war file but gives error in deploying the jar which has the ejb. I have aslo validated the jar using ejbc.
It gives error indicating that it requires struts.jar in classpath. If we give the classpath of struts.jar at system leve the Application deploys with ease..Can anyone tell whats the error.The jar does not use any strust component .
4>Also the valueobject which has some beans which are used to populate the jsp through Actionformbean. Is it ok if we give refrences in both ejb jar and war?
ie while creating jar and war folder have the valueobject in both the files or will it lead to any errors..
Thanks in Advance

Yes, I have tried that. But, as the server is running and the jars are in use, it throws and EditFailedException

How to include external .js file into .ear file using NetBean 5.5.1?

I am using JBOSS 4.2.2 GA as server
thx!!

Even this is also not possible because, the code in that package is developed by DWR and i am just adding it to my lib folder and importing the respective classes. In the same manner i need to include the *.js* file in the JSP.It took me about 3 minutes reading through the [DWR Getting Started|http://getahead.org/dwr/getstarted] page to learn that you don't have to do any of that. Perhaps you should read that page?

Jar, War or Ear file ?

Hi,
I am a total newbie in J2EE technology.
I am currently using Sun One Application. Using the sample application, it produces all the Jar, War and Ear files.
My understanding is Jar is produced to be a library-like usage.
War is for web application.
And Ear is for what?? oops EJB? Can someone tell me?
Anyway, my concern is, if I am to produce Ear, war, or Jar file after deploy, I have problems doing the testing. Let's say I want to modify the Jsp file, then I have to use ant to compile all, undeploy the instance and deploy again.
Any better way?

your jar files contain your EJBs, your WAR file contains your web application (JSPs, servlets and support) and these are all bundled into your EAR file. All of these files are just zip-formatted archives, you can look at them all via the jar tool (or something like WinZip, if you are so inclined). Each of these will contain a descriptor file (in XML format) - check out the J2EE spec on it.

Including utility jar when packing ejb in weblogic

Hi,
I am new to j2ee programming. I have an ejb which uses some utility jars. I followed the bea documents to structure the directory. The directory structure is, like,
EjbProject
- classes
--com
---mine
----projectTracking --> has the class files of the ejb and supporting java files
- src
--com
---mine
----projectTracking --> contains the source files of the ejb and the supporting java files
META-INF > contains ejb-jar.xml and weblogic-ejb-jar.xml
The source java files are dependent on an utility jar file.
so when I try the java weblogic.appc src, it throws me exception saying the utility file is missing. My question , is where should I put this utility jar file. Please send me your thoughts.
Thanks in advance

Hi,
you can put your utility jar in the ear file along with the EJBs and make a classpath entry to these files in the EJB jar's META-INF\Manifest.mf file. As you said if you are working with weblogic you can put these files any where in the directory structure and place the entry in the startWeblogic.cmd file. But i recomend first option.

Including a jar file inside an executable jar file

Is it possible to include a jar file inside another (executable) jar file such that the included file is part of the class path for the outer file? If so, how do you specify this in the classpath in the manifest?

Russ_Bjork wrote:

What do you see as the advantage of doing that?
Is your app. a rich client (e.g. Swing, AWT, SWT..)?
Can you distribute the app. from a server or the internet?

How to include ojdbc.jar with applet in apex

I am integrating applet with apex. I need to use ojdbc.jar to connect to Database. How can i include this jar. I tried uploading it as a static file. But i am not sure how to embed it with applet code in region source of a page. I am using following code to embed the applet.
<applet code="TestApplet.class" archive="#APP_IMAGES#Test.jar" width="500" height="500">

Please suggest how to include the ojdbc.jar.

Thank you all for help, from your posts I was able to get the datepicker working with a different version of jQuery (but not jQueryUI) included on the page. There are two methods:
1. Include the new library before #HEAD# and change the reference to a different variable, for example:
<script src="jquery-1.6.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
var jq164 = jQuery;
</script>
#HEAD#2. Include the new library after #HEAD# and enable noConflict() mode, for example:
#HEAD#
<script src="jquery-1.6.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
var jq164 = jQuery.noConflict(true);
</script>In both examples above, $, jQuery and apex.jQuery point to apex jQuery, while jq164 points to the new one.
However, I couldn't manage to include a newer version of jQueryUI. I only found a page ([url http://stackoverflow.com/questions/6358961/using-multiple-jquery-ui-versions]http://stackoverflow.com/questions/6358961/using-multiple-jquery-ui-versions) that says you have to specify a different context for each version of jQueryUI included on the same page. I haven't yet had time to look at this, so if anyone already knows how to do it, it would be really nice to share it with us.

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.

Include many jars for a complex signed applet in html file??

hello
I'd like to know how it's possible to put a signed applet in an html file, that needs many jar files.
I explain myself: I know that to create a signed applet and to put it in an html file, I need to create a Jar file that contains this applet, create a private key with keytool, sign the jar and include it in my html file with the tag <applet code="....." archive="......jar".... />
This works fine if my applet is a simple program that only uses the clases present by default in the jdk.
In my case, I have a big project, with many packages. In one of these packages, I have my applet that uses some classes of the other packages, which use classes from imported jars, such as BouncyCastle, and others...
There is still no problem when I run the applet from the applet viewer.
The problem appears when I put the JAR file with all these classes in the html file: there is a problem since it doesn't know anything of these classes imported from these jars.. It's quite obvious actually.
My question is: how do I do to make the html file aware of these classes? Is there an html tag that allows us to include many jar files? Do I have to decompress all these jars, take all the directories, add them to the directories of my project and create a BIG jar (that's what I did, but it's really dirty, and heavy! (11M))??
Does anyone have an idea about how I can do it?
Thanks for your help
Philippe

11 MB is pretty big for an applet.
Let's say your applet uses java 3d, normally a client would download and
install this seporately, meaning the jars needed end up in lib/ext directory where
any applet can find them.
Check what applets need to be installed (put in lib/ext) and what can be
downloaded:
<object .....
<param name="archive" value="myJar.jar, myOtherjar.jar" />

First, you need to be able to boot from the Recovery HD:
Boot Using Command+R keys:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"COMMAND" and the "R" keys together.
3. Release the keys when the Utilities Menu appears.
Once at the Utilities Menu select Terminal from the Utilities menu in the screen's menubar. Now, you need to know where these new files are located. You move to any location using the 'cd' command such as cd /Users/user_name/Documents, then press RETURN. Replace user_name with your actual username. Next you need to do a directory listing to see if your files are in that location, Documents. Use ls -al to do a directory listing of the files and folders in Documents. If you find your new files there, then connect an external drive or flash drive. You will need to know the name you have assigned to this drive. It needs to be already formatted. Copy your files using cp /Documents/filename /Volumes/volname/filename. Replace volname and filename with those that apply. Press RETURN.
Or take it to your local Apple Store and see if they can do the chore for you.
