J2EE Enterprise App Directory Structure

Can anyone point me to a resource that descibes the recomended development directory structure for a J2EE app with EJB? MyEclipse create three directories:
J2EEAppName
J2EEAppNameEJB
J2EEAppNameWeb
But I don't know where to put the shared classes, etc. I want to do it right.. Any help would be greatly appreciated.

Apps Directory Structure

Hi,
With the help of many good posts on this forum I got 11.5.10.2 Apps running on Suse Linux 9.0. I installed Vision Demo database and the installation location is
/opt/oracle
under this directory following directories have been created by rapidinstall
visappl
viscomn
visdata
visdb
visora
Could someone please educate me about this directory structure.
Also where should my environment variables like ORACLE_BASE and ORACLE_HOME point, which environment files should I put these env variables so that these get applied after reboot automatically.
Thanks in advance.

Hi Ravi
Let me answer to your query...
What all i understand you want to know the file structure, as you have installed vission DB thus
visappl - APPL_TOP
viscomn - COMMON_TOP
visdata - data_top (data top for appl utilies 806 home)
visdb - database
visora - ora_top
There are 2 oracle home
1) 9i oracle_home which I feel must be -- visdb
and
2) 806 oracle home which is visdata
8.0.6 oracle home is ussed for apps utlities adpatch/adclone etc
when you source different environment file you then see the difference
FYI
appl_top env file --> $APPL_TOP APPS<SID>_server.env
let me know if you still have doubt

Web app directory structure

Is there some standard directory structure when building J2EE web application that consists for example JSP pages, servlets, EJB components, pictures etc.

place all your jsps in "jsp" folder under the project folder.
Create a folder called "WEB-INF" under the project folder which contains all your servlets, and web.xml and taglib.tld files. Your servlets that is .class files should be in a folder "classes" under "WEB-INF".
The .html files and picture files are under the project folder.
I hope it will help you some how.
But, the directory structure depends upon the Framework you are using such as Struts, Spring or Axis.

Directory structure for a J2SE+J2EE project: suggestions are very welcome

Hi, I have to start coding and organizing the CVS tree of an already mature project which is J2SE. This J2SE project can be described as a "core engine" for something else, and is a quite large project, and up to now has only a command line User Interface. I organized the dir structure as this:
/build.xml
/src/
/src/java/<package>/...../*.java
/src/demo/<package/...../*.java
/src/test/<package>/....../*.java
when I ant compile, all the .classes will be done in the "build" directory (reflecting the structure in the "src" dir):
/build/
/build/java/<package>/....../*.class
/build/demo/<package/...../*.class
/build/test/<package>/..../*.class
I am happy with this, but now comes the issue: a web interface to use this core engine (it will have the same package namespace) is in developing progess, so I have to put somewhere the *.jsp, the WEB-INF dir with web.xml and servlet sources: how would you do this? And where would you let Ant put the compiled servlet classes?
I can modify the previous directory structure to accomodate the J2EE part, this is really not a problem!
Thanks to who can suggest me a clean solution

Create a web-inf folder at the same level of src and
jsp folder inside src
i mean
/build.xml
/src/
/src/java/<package>/...../*.java
/src/demo/<package/...../*.java
/src/test/<package>/....../*.java
/src/jsp
/web-infSo, would you put in /src/jsp only the *.jsp?
And what in /WEB-INF ? What woud you put there? Would you do something like:
/WEB-INF/web.xml
/WEB-INF/src/<package>/..../<my_servlets_and_j2ee_stuff>.java
/WEB-INF/classes/<package>/..../<my_servlets_and_j2ee_stuff>.java
In this manner sources and classes are in the same tree, it does not seem very clean to me, expecially if you consider that probably I must have a "test" directory to unit test some j2ee stuff (as for the j2se stuff in "src"): how would you do that?
Is this directory structure anyway what you meant or not?

An EFFECTIVE development directory structure for J2EE platform?

Hi, here we r talking about deployment environment more than development
environment. Have u ever think about designing an EFFECTIVE development
directory structure for J2EE platform( e.g. weblogic )? u r not using the
deployment directories for coding, r u? :)
I used to construct a dir structure for dev and want to improve it.
d:/wholesystem/*.prj // Project files
...../module1/src/com/.... // Module source files
...../module1/doc/... // Module doc files
...../module1/classes/... // Module class files
...../module2/...
...../web/*.jsp // web page files
...../web/images/... // web page images
...../web/WEB-INF/... //...
Do u have any good ideas? Thanks!

J2EE Deployment 1.1 API and Split Directory Structure

How do you think the Deployment API from J2EE 1.4 will affect the WL split directory
structure?

I believe they're orthogonal and wasn't expecting any split-directory
changes. Did you have any particular concerns?

Directory Structure ?s for an Exploded Web Application

We have an application that consists only of JSPs and Servlets, no
EJBs. I am researching whether or not it's worthwhile to start using
EJBs. We're also migrating from Weblogic 5 to 6.1. I've managed to
migrate our application fine and have it up and running on WLS 6.1.
I'm confused about the exploded directory structure, the
application.xml file, where to put the EJBs and whether or not I have
to jar them. Here's our current directory structure:
DefaultWebApp/               JSPs here
DefaultWebApp/WEB-INF          web.xml and weblogic.xml here
DefaultWebApp/WEB-INF/classes     Servlets and other classes here
DefaultWebApp/WEB-INF/lib     do my un-jar-ed EJBs go here?
I've been reading a lot of BEA's documentation, particularly
‘Deploying an Exploded J2EE Application' and a ‘Web Application PDF',
and looking for relevant threads on the weblogic.developer.interest
groups. It looks like the application.xml should go in a new
DefaultWebApp/META-INF directory. But where do the EJBs go?
I also see some directory structures with another /web directory
that's confusing me.
Oh, I've also managed to compile and jar up a trial Stateless Session
EJB. Then I think I ‘auto-deployed' it into the /applications
directory, and Weblogic seems to recognize it. But when I tried to
reference it in a JSP, I got an error message ‘class x is public,
should be declared in a file named x.java'. I'm assuming this is
related to the application.xml, where I need to define the ejb
directory.
Thanks.

To deploy your web app together with your EJBs, you need to create
an "EAR" structure. Both your webapp and your EJB jars will be within
this new structure, at the same level. You may jar up your EJBs, or you
may explode their structure, it's up to you.
The resulting structure should look something like below:
EnterpriseApp/ <-- new top level
EnterpriseApp/META-INF/
EnterpriseApp/META-INF/application.xml
EnterpriseApp/lib/ <-- shared libraries (if any)
EnterpriseApp/EJB/ <-- ejbs go here
EnterpriseApp/EJB/META-INF/ejb-jar.xml
EnterpriseApp/EJB/META-INF/weblogic-ejb-jar.xml
EnterpriseApp/EJB/com/your/ejb/classes/here
EnterpriseApp/WebApp/ <-- move your current app here
EnterpriseApp/WebApp/index.jsp <-- JSPs goes here
EnterpriseApp/WebApp/other.jsp
EnterpriseApp/WebApp/WEB-INF/web.xml
EnterpriseApp/WebApp/WEB-INF/weblogic.xml
EnterpriseApp/WebApp/WEB-INF/lib <-- ui libraries go here
EnterpriseApp/WebApp/WEB-INF/classes <-- servlets go here
The above structure is identical to the structure to an EAR file, only "exploded"
as actual files and directories instead of being "jarred" into a single EAR file.
Your application.xml in this case would specify something like:
<application>
<display-name>EnterpriseApp</display-name>
<description>My Enterprise Application</display-name>
<module>
<ejb>EJB</ejb>
</module>
<module>
<web>
<web-uri>WebApp</web-uri>
<context-root>/yourAppRoot</context-root>
</web>
</module>
</application>
And in config.xml you would have an entry similar to:
<Application Deployed="true" Name="EnterpriseApp"
Path=".\config\mydomain\applications\EnterpriseApp">
<WebAppComponent Name="ui" Targets="myserver" URI="WebApp"/>
<EJBComponent Name="ejb" Targets="myserver" URI="EJB"/>
</Application>

Web Application directory structure

Please can someone help me with directing me to any online guide as to how webapp could be created and web.xml configuration in Sun Application server 8.
I do not understand the directory structure of sun, unlike Tomcat the webapps contains all the virtual context part with a default ROOT direct set in the server.xml as the default docbase.
Now, where is the default ROOT in Sun server? Where can I put my index file. When I create a web context, where will I put it? Does J2EE has similar WEB-INF structure in Tomcat? Does it have web.xml to configure the webapp
Finally, I have written a simple EJB called Hello World using stateless protocol. I have my Hello.class, HelloHome.class and HelloBean.class. I also have ejb-jar.xml for container configuration. I have jar then up to hello.jar and have deployed them. Now I want to access the beans, Home bean to be precises. I have written a hello.jsp and I put it in the orignal directory where the main index.html file is in Sun server which is /user/Sun/AppServer/domains/domain1/docroot, I got errors.
Could someone shade a light on this please.
Thanks Guys.
NB
Do not point me to online reference
I have awared max point for this question

The developer's guide discusses in pretty clear terms how to deploy a J2EE app from a directory structure.
The tomcat directory structure is really the same as a packaged war which once you read the documentation you will see is basically no different with SJSAS.
You need to deploy an application. See previous posts on how to have docroot be the top level (search for posts by janluehe)

Directory Structure for Discoverer

I have couple of queries...
1. What is the directory structure for discoverer on Unix in Application Server?
2. Is there any extention for the woekbook saved in the database like .dis?
I am working on discoverer 10g with Oracle Apps.
Thanks...

1. On a Solaris machine where I have Discoverer 10g (9.0.4.3) installed the directory structure for the Oracle home looks like this:
$ cd h9043
$ pwd
$ /home2/h9043
$ ls
Apache install.platform opmn srvm
BC4J inventory oracore sso
JRE j2ee ord syndication
OPatch javacache otrace sysman
assistants javavm oui tk
bibeans jdbc owm tools

Using wlappc with split directory structure

I am trying to generate an EAR file of my application using wlappc in WLS8.1sp3.
I am using the split directory structure, I have a src directory containing my
source and xml descriptors, and a output directory containing the compiled classes.
I am using the split structure to deploy to the app server in development, that
is working fine. I use wlcompile to compile the code, that works ok too.
I assume that the purpose of wlappc would be to take a split directory structure
and create an EAR file from it, but there is only one source directory that you
can pass to the ant task. If I pass the src directory, it complains that it cannot
find the classes. If I use the output directory, it complains that it cannot
find the META-INF directory.
Am I missing a step? Do I have to use wlpackage to put everything in one directory,
then wlappc? Do I have to copy the class files or xml files manually first?

will do hundreds of checks against your EJBs to make sure they comply
with the spec. It will compile your JSP files into servlets etc. You
just need to pass wlappc the output directory. It will automatically
find the src directory.
When you're ready to deploy to a production or staging server, you can
use wlpackage to put everything into one directory or an archived EAR file.

Directory Structure for multiple applications at one host

Can I have multiple (more than one) WEB-INF directory structures in the public_html directory for different web applications? If I do this, how do setup the url-pattern in the Servlet Mapping tag in the web.xml file? How do I setup the URL that calls the servlet from the HTML that has been send to the user�s browser?

If I understand your question, you want multiple contexts. All App Servers/Web Servers allow you to setup multiple contexts. Normally if your root context is in /home/myhome/app_server/
then you would setup multiple contexts by creating a folder for each context:
/home/myhome/app_server/context1/
/home/myhome/app_server/context2/
Each would have their own full application/website. And the way to reference these would be as such:
if the domain, www.mydomain.com, is mapped to /home/myhome/app_server/
www.mydomain.com/context1/
www.mydomain.com/context2/
I think that is what you were asking. Hope it helps

Deployment of RDF File in Oracle Apps Directory

Hi,
I am facing problem in deploying the custom RDF file in Oracle Apps Instance.
My RDF file works fine when it is deployed in the XXASO directory structure with Profile option ASO:Print_Report_Directory set to XXASO directory.
But When the same RDF File is deployed in ASO directory structure with
Profile option ASO:Print_Report_Directory set to ASO directory it throws error.
Can anybody please Pour light on this.

Its very urgent for me,CAn u please spare some time and throw some pointers on y it is behaving in this manner?and what all i need to do for it to pick my report from custom top.

Creating a Standby Database with the Same Directory Structure

Hello gurus,
I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
Thanks in advanced.

Uwe and mseberg: thanks for your quick answers
I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
Do you understand my doubt? Excuse me for my english.
Thanks.

Directory structure for the new Data Services Project

1) I do as prescribed in the manual "Building and deploying
Flex 2 Applications", page 325
"To create a web application make a copy of the /flex
directory and its contents. Rename the copy and store it in the
same location under /servers/default directory."
("flex" is an empty Flex Data Services application that
serves as a template for creating your custom application)
2) I create a corresponding project from Flex Builder 2 :
Project type: Flex Data Services
Root folder: C:\fds2\jrun4\servers\default\MyDS
Root URL:
http://localhost:8700/default/MyDS
Project name: MyDS
Project contents: C:\fds2\jrun4\servers\default\MyDS
2) I build the project
Immediately after "build project" the directory structure at
C:\fds2\jrun4\servers\default\MyDS becomes the following:
.settings
bin
----------------META-INF
----------------WEB-INF
---------------- --------------- classes
---------------- ---------------flex
--------------------------------jsp
--------------------------------lib
-------------------------------sessions
html-template
META-INF
WEB-INF
----------------classes
----------------flex
----------------jsp
----------------lib
----------------sessions
Notice that bin directory now contains another pair of
META-INF and WEB-INF in addition to those already existing in the
template project "flex".
Can anybody comment on this directory structure?
Which META-INF and WEB-INF are supposed to be used for
configuration?
What is the purpose of having two pairs of META-INF and
WEB-INF in the same web app?

Hello -
first, those folders are necessary in deployment - You need
only the contents of the bin folder for deployment, not the
sources. Since you're compiling the application locally in FB2 it
places all of the supporting and necessary files into one location
namely the "bin" folder. You'd deploy the "bin" folder's contents
to the FDS server, perhaps another FDS server that is not your
"development" server -- like a production server. The data and
configuration information that your app needs for FDS services are
stored in the WEB-INF and META-INF folders so these need to travel
with the final product. On the production server you'd just cop the
"bin" folder and it's contents to the /servers/default folder -
where you could then rename your bin folder to "MyDS"
HTH, Bill
