Deploying an existing WAR file into the Portal

I have downloaded the Enterprise Portal and the SAP Netweaver Developer Studio (NDS) and have succeeded in creating a couple of projects of the Hello World variety and deployed them on the Portal! So far, so good.
The problem I have is that need to deploy on the Portal an existing JSP/Struts application of ours which is available as a Web Archive (WAR) file.
The problem is that I cannot find a way of deploying an existing WAR file on the Portal either via a Project or otherwise. I have found an entry in the Help files with the NDS which sounds promising, as it is entitled Import a .WAR File into a new project. However, the menu entry it says you should use (File ‑> Import ‑> MDK: Import a web archive (.WAR) into a new project) this last entry does not exist on my installation of NDS.
Any ideas or suggestions?

Hi Mustafa (and All) - thanks you very much for your answers, which has enabled me to make good progress.
I have created a project in the Deploy Tool, imported a simple WAR file into it, loaded to project and depployed it on my instance of the Portal - or at least I have deployed it as far as the Deploy Tool is concerned.
However, when I try to find it in the Portal in order to assign it to an iView in the Portal content, I can't find any evidence of its existence!!
As another 'tack' in the NDS I have created an 'Enterprise Application Project', into which I appear to have imported the WAR file - but I cant package this as a PAR file, which is what I seem to need to do to get it into an iView on the Portal. To create a PAR package I seem to need to create a 'Portal Application Project' - but I can't find a way of getting the WAR file into that!!
Any further advice would be greatefully received.
Thanks for your help to date and thanks in advance for any more you may be able to give.
Regards,
Dave

Deploying a war file to the portal server

How to deploy jsr168 war file into Webcenter Portal

I want to intergated a jsr168 war file with Web Center Portal. I only install WebCenter Portal without JDeveloper and Content. So how should I deploy it?
Thank you!
Regards,
Jugela

You have the weblogic domain right ? Opent the enterprise manager in browser by hitting the below url -
http://<Admin Server address>:<port>/em
login with credentials.
From deployments end,you can install the war file which will targeted to WC_Portlet server.
After that register the portlet WSRP url with your application and use it.
The above suggest is without the intervention of jdeveloper /webcenter.

Deploying Java Web Application (WAR-File) into a cluster environment

Hi,
we have a web application which has to read from and write to the file system.
Since a short time we have a cluster environment (2 parallel servers) and since thisa time we have the problem, that files are worked double in the cluster. The application is working on both servers now and so we have this problem.
Does anybody know how we have to deploy the application correctly in a cluster environment or do we have to change anything in our source code of the application?
I didn't find any documentation about this.
At the moment we have deployed the application on one of the two servers only, but I think there must be a better way to solve this problem.
Thanks for your replies.

Thorsten

Adding files to the portal

Hi
I have an HTML form which has an <input> of type "file." I want to enter a file into the portal, into a specific folder within a specific content area. Supposedly, all I need to do is use the wwsbr_api.add_item function. I've created a PL/SQL procedure which I call from my HTML that what it does is get the parameters from the HTML form (the file name), and then apply the add_item function.
(I do know the folder's and the content area's id).
It's not working. I'm getting an ORA-29532 Error. (some Java security exception)
So, how do I enter a file directly into the Portal?
(A code example would be great!!!)
Thanks,
Dan
p.s
I've seen in some example where they use a wwv_.....saveitem function (cant remember the package name -- I could look it up if anybody is interested). This function is not documented anywhere, and so I'm afraid to use it because I dont understand all the parameters, and who knows what changed they'll do to it in the next version and I wont be able to use it anymore....

Dan,
You have two options.
If you want to upload the document via a browser - then use the add_item_post_upload function (vs the add_item function).
This function assumes that the document is already uploaded and that the p_file_name being passed is the actual document 'NAME' returned when the document is uploaded.
The other option is to use the add_item procedure and put the document somewhere on the same machine as the database
-- then the value for p_file_filename is expected to be "The full directory and filename for the file to be uploaded for this file item. The file path must be visible from the
database machine." If this method is used then the document will be uploaded from the directory into the database as part of the add_item function.
Hope this helps.

Before deploying the app, you could check database table PF_PORTLET_DEFINITION for any entries there which might conflict with yours.

How to check who has deployed a PAR into the portal

Hi there,
is there any log from which can be checked who has deployed a PAR into the portal (probably using NWDS directly)?!
Thanks in advance
Praveen

Hello Praveen,
You can find the user info from the trace files which are located in usr/sap/SID/DVEBMGS<SysNo.>/j2ee/cluster/server0/log/ subfolders.
Try to extract the info from the Tracefiles.
Again if you have the Logviewer configured then you might be able to find the same info there too.

Do i have to pack all files into the war file/

Hi,
suppose a file (say bb.html, for example) within a war has a link to a document outside the war, say c:\aa.doc for example, after deploying the war into the j2ee application server, the linked file cant be found, simply because the file(aa.doc) isn't packed with bb.html. I am wondering if there is a way that I can establish the link, even they are placed in different location.
to exend the question, in my understanding, the web container within the j2ee application server is a Tomcat run evironment, do I need to connection the applicaiton server to one of web servers like appache web server, IIS etc to get better preform? if yes, how?
Can anyone give some explanation please?
Thank you very much!
Ken

No they do not have to be packed into the same War file.
The application server does have to know where they are so that it can handle requests for a given "html" file.
For example: "bb.html" was found in the war file you deployed.
it links to "aa.doc" - where is the directory or war file that contains "aa.doc"?
It too needs to be "deployed" within the server in order to be found.
I hope this helps.

Problem in deploying WAR file into OC4J

I have tried deploying a .war file into oc4j (orion) application server using - Deploying Upon OC4J Server Startup option
I have placed the intelliview.war into /applications directory
modified server.xml & web-site.xml
server.xml added
<application name="intelliview" path="../applications/iviewserver.war" auto-start="true" />
web-site.xml added
<web-app application="intelliview" name="iviewserver" root="/iviewserver" />
Here is the error message,
Error instantiating application at file ....applications/intelliview.war
Unable to read/find assembly info (META-INF/application.xml)
Any idea?
Thanks

Following are the steps involved in deploying a WAR file in Oc4j.
1. Copy the file to D:\oc4j\j2ee\home\applications where d:\oc4j is the location OC4J is installed in.
copy mywar.war D:\oc4j\j2ee\home\applications
2. Open the application.xml file in D:\oc4j\j2ee\home\config directory
and add the following after the <web-module id="defaultWebApp" path="../default-web-app" />
line:
<web-module id="mywar" path="../applications/mywar.war" />
3. Open the default-web-site.xml file in D:\oc4j\j2ee\home\config
directory and add the following after the <default-web-app application="default" name="defaultWebApp" /> line:
<web-app application="default" name="mywar" root="/mywar" />
Hope this helps

Unable to Deploy Par File in the Portal

Hi Experts,
When i'm trying to deploy the par file to the portal after Configuring the server settings it's giving me an error.
"Operation Failed: Please make sure the server 'DEV' (hostname:port) is running or check the log (sap-plugin.log) for more detail "
And please guide me where i can find the log file sap-pluginng to check the logs as i'm new to the NWDS i'm not able to locate the file.
Regards,

Dear Nilesh,
Check that you have set the followings configurations:
- Windows -> Preferences -> SAP J2EE Engine:
Message Server host: Portal Server
Message Server port: ms of portal 390x (not 50x00) you cand find your message server port in http://server:port/index.html -> System Information (Message server table)
- Windows -> Preferencies -> Sap Enterprise Portal (there you need to put the 50x00 port).
Try with this a comment, regards.

How Do You Deploy a War File to The OC4J Standalone ?

I have a .war file that contains example code and I would like to deploy it to my OC4J Standalone.
I tried putting the war file in the applications directory and adding a line in the server.xml file but I received the error:
Error instantiating application at file:/C:/OC4JStandAlone/pdk101202_oc4j_extended/j2ee/home/applications/displaytag-examples-1.1.war: Unable to find/read assembly info for C:\OC4JStandAlone\pdk101202_oc4j_extended\j2ee\home\applications\displaytag-examples-1.1 (META-INF/application.xml)
It appears it was expecting an .ear file instead of a .war file
Is there an easy way to deploy a .war file to the OC4J Standalone?
Thanks,

Please refer to the OC4J FAQ on :-
http://www.oracle.com/technology/tech/java/oc4j/1012/collateral/OC4J-FAQ-101202.pdf
Q 24 should have your answer.
Cheers!

Deploying WAR file into OC4J 9.0.3 (IAS)

Hello,
I try to deploy my WAR file using following command:
dcmctl redeployApplication -v -d -f myWAR.war -a myApp -rc /test/myApp -co test
When the deployment is finished I check default-web-site.xml for the "test" component and I a new line there:
<web-app application="myApp" name="myApp" root="/test/myApp"/>
But in the documentation I found that the "name" attribute of the "web-app" tag should contain the name of the WAR file. It is a problem because when I try to deploy another WAR file using the same application name it overwrites "<web-app>" tag. In principal, can I deploy several WAR files using the same application name?
Thanks in advance,
Iouri.

Please look at the following thread in this forum that describes the steps : Re: Query takes large time to execute

I just purchased a new MacPro to replace my existing 2006 MacPro which cannot be undated with the new operating system. My question is what is the safest way to transfer all my files. 1) simply install my existing 2TB HD into the new Mac Pro or 2)

I just purchased a new MacPro 3.2GHz Quad-Core Intel Xeon processor to replace my existing 2006 MacPro 2 x 2.66 GHz Dual-Core Intel Xeon because it cannot be undated with the new Lion operating system.
My question is what is the safest way to transfer all my files to the new computer. 1) simply install my existing 2TB HD into the new Mac Pro, set it as the startup drive, and update its10.7 operating system or 2) or use the migration program.
I'm concerned that simply installing the existing 2TB HD, I may have issues with it not recognising some infromation written for the old 2 x 2.66 GHz Dual-Core Intel Xeon.

your new system runs 10.6.8 just fine as has been said and stated many times.
I would clone it first.
I would even clone the original system it has.
And if you have or want to use Lion and then Mountain Lion, fine - I would still keep backups of every OS.
I am not a fan of putting the OS and Apps plus all the data all on one drive. I like to keep them separate.
Whatever OS, rerun the last combo update is all and any other updates.
And by "new Lion" I assume you don't mean 10.7 but "Moutain" 10.8. Part of me says keep Lion and SL around, and test and try out ML with your apps and other hardware you may have. After too many years, waiting for 10.8.1 - and give everyone time to update their apps and retest.
