Oc4j versus apache

Hi
I have a minor problem with apache-oc4j ...
Given a host name proposed by oracle as while installing all the stuff.. let say x.y.local...
using this host to access a j2ee application works perfectly, from anywhere on the network.
this server have alternative names, let say aHostName. When i use this the web application still work, excepts in one place. When i access a resources constrained to a role and i dont have the role, the redirect is from aHostName to x.y.local ... causing some problems to our application... We suspect that apache override some http header info about the hostname..
Any idea ?

You can try setting the UseCanonicalName, which defaults to be on, to be off in your Apache/Apache/conf/httpd.conf file. Or you can set your ServerName to aHostName instead of x.y.local.

OC4J Versus 9ias

With all the fuss over OC4J, what is the strategic importance of using OC4J versus deploying your application on 9ias? Is there something proprietory within 9ias that would be a dis-incentive? A response from would be greatly appreciated. When it seemed ORACLE had something stable they suddenly seemed to have created a whole lot of confusion!!

Rajendra,
Before OC4J, we had the Oracle JVM running inside the database. This meant that users had to install a database to run J2EE applications. Though there were some benefits of running J2EE applications with Oracle JVM, there were some usability issues
and our customers gave us feedback that they did not like to idea of installing a database ( in the middle tier) to run J2EE applications. To address these and other concerns OC4J was launched about 6 week back.
Oracle JVM will continued to be enriched to run Java stored procedures and server -side JDBC and SQLJ. For your J2EE needs, please use OC4J. It is easy to use and very fast as another person on this thread mentioned.

OC4J behind apache

Hi All,
OC4J and Apache can both be used as Web Servers. OC4J contains
its own Web server, but as per OC4J documentations it is
recommended that you configure for handling J2EE applications
behind Apache. Is there any advantage in using Apache for
processing proxy requests instead of OC4J?
can anyone reply?
Regards,
Yogavelan

Another reason is for ModPLSQL which can only be accessed from
Apache. You could use DB Prism 1.2.1/2.0.0 with OC4J to replace
mod_plsql with a complete servlet technology, but with other
features such as calling PLSQL code from jsp:include or
jsp:forward tags, integration with Apache Cocoon framework, and
so on.
DB Prism is at http://www.plenix.com/dbprism/
A dpls.ear file which is preconfigured as mod_plsql is ready to
use with OC4J at: http://www.plenix.com/dbprism/dist/dpls.ear
Best regards, Marcelo.

Deploy JSP, XSQL-XSL Application on OC4J or Apache?

I have an application having JSPs and XSQL-XSL pages (not EJBs)
for the internet.
Which is the best deployment type?
- Running both on OC4J (after installing XSQL),
- Running both on Apache,
- Running one on Apache and other on OC4J?
What about using Apache as a proxy sending requests to OC4J?
Thanks.

I deployed both on Apache (JSP,XSQL) and I have another PC with Apache as Proxy.
It works fine. I dont know the performance when many users try to connect.

Performance advantage to standalone OC4J versus App Server?

If one uses only the JMS server part of the 10g Application Server, would there be any performance advantage to running the standalone version of the OC4J JMS server versus running the entire application server?

Are you saying there is zero overhead associated with passing JMS messages through the application server?
Logic suggests a performance increase when a step is removed...

Configuring OC4j with Apache HTTPD server

I want to use OC4j as servlet container and Apache Server as a
Http server handling all static requests. Now as per the OC4j
documentation I created a OC4j.conf file and included the same
in the main httpd.conf file.
However I could not get my servlets running.I get the page not
found error.Can you suggest a way out.

Hi,
Try this step.
Comment the following statements from your Jserv.conf file in
<oracle_home>/Apache/Jserv/conf :-
ApJServMount /servlets /root
ApJServMount /servlet /root
Still not working, reply.

OC4J and Apache Virtual Hosts

Server Setup
OS Version: Windows Server 2003 64bit
Server Version: Oracle-Application-Server-10g/10.1.3.1.0 Oracle-HTTP-Server
API Version: 19990320:18
Run Mode: standalone
I have setup two seperate Apache VirtualHosts address1.mycompany.com and address2.mycompany.com I have also setup 2 seperate OC4J application groups appgroup1 and appgroup2. I need to tie appgroup1 to the virtualhost address1.mycompany.com and appgroup2 to address2.mycompany.com. There will be two seperate applications running on each app group and they both need to run at the root level of the address .... instead of running like so address1.mycompany.com/application1 ....
Is this possible to do with this version of Oracle Application Server. I have seen that in the Weblogic version there are ways in which to do this, but due to a deadline and my limited knowledge of Weblogic at this point I am unable to go that direction ... Any help with this would be greatly appreciated and well recieved.

Hi,
I have a similar problem, I'm running apache 2.2 on windows and oc4j 10.1.3.4.0.
I'd like to map http://app1.example.com/home.html in apache to http://10.1.1.3:8888/app1/home.html and http://app2.example.com/home.html to http://10.1.1.3:8888/app2/home.html
I have the ProxyPass settings in my httpd.conf file
ProxyPass / http://10.1.1.3:8888/app1
ProxyPassReverse / http://10.1.1.3:8888/app1
This works fine for the first URL and the browser shows the correct page at http://app1.example.com/home.html however as soon as I click a link in the page the browser tries to go to http://app1.example.com/app1/page2.html
And since I have my ProxyPass mapping in apache, I think its trying to get to the following page in oc4j http://10.1.1.3:8888/app1/app1/page2.html which doesn't exist.
Is there any way to map a subdomain/virtual host to an oc4j context but hide from the browser the oc4j context in each of the URLs.
To make matters more tiricky (or maybe not), I'm using Struts 1.3.10 as my application framework, so I don't normally construct the <a> links myself but have Struts do that for me with <html:link> tags.
Thanks in advance for any pointers,
Andy.

Oc4j behind apache - possible to prevent hitting oc4j port directly?

Hello -
Is it possible to configure OC4J standalone running behind apache to accept only requests coming from apache instead of hitting OC4J's port (8888) ?
We use OC4J stand-alone (9.0.3) behind Apache (1.3.x). We use mod_proxy to send requests from apache to OC4J. The directives in httpd.conf look like this:
ProxyPass /myApp http://myserver.xyz:8888/myApp/
ProxyPassReverse /myApp http://myserver.xyz:8888/myApp/
Therefore, a user typing http://myserver.xyz/myApp will get their request sent to OC4J.
Question: Is it possible to configure OC4J so that it only responds to request going through mod_proxy. i.e., I want to PREVENT someone from accessing myApp by hitting 8888 directly through their browser. Possible?
Thanks.

Hi there,
if you specify the host in you web-site.xml (eg. <web-site host="127.0.0.1" port="8888" display-name="The Web Site">
), then oc4j should only respond to requests from localhost and shouldn't be available externally via apache...
all you should need then is to modify your proxypasses like so:
ProxyPass /myApp http://127.0.0.1:8888/myApp
ProxyPassReverse /myApp http://127.0.0.1:8888/myApp
hope this helps,
Andy

Using OC4J with Apache Web Server

Hi,
I followed the instruction to put the following lines in apache/config/httpd.conf:
<IfModule mod_proxy.c>
ProxyRequests On
ProxyPass /servlet/ http://sundev.ultradns.net:8888/servlet/
ProxyPassReverse /servlet/ http://sundev.ultradns.net:8888/servlet/
</IfModule>
I can access my servlet as:
http://sundev.ultradns.net:8888/servlet/MyServlet
But when I tried to access through apache server as:
http://sundev.ultradns.net:80/servlet/MyServlet
I got an error:
The requested URL /servlet/MyServlet was not found on this server.
Thanks,

Are you using OHS aka Apache from an Oracle9iAS install. In Oracle9iAS, there is another servlet engine Jserv configured for URI /servlet and this is causing the problem.
If you are not using JServ then you can disable Jserv by commenting out the directive for mod_jserv in your httpd.conf file and this should work fine.

Apache in front of OC4J? AJP13?

Hello,
I need to place OC4J behind Apache.
I have a working Apache setup that talks to JBoss/Jetty via AJP13 on port 8009. How can I configure OC4J to listed to some port and listen for AJP13 requests?
Does OC4J come with its own protocol and Apache module?
When I start OC4J and use `nmap' to check which ports OC4J is listening, I only see port 8888, which is OC4J's internal HTTP server. I want to put Apache in front instead.
I couldn't find any documentation about this, so any help would be great.
Thanks,
Otis

For 9.0 PE you can also use the apache mod_jk plugin to have an apache in front of Glassfish/9.0PE. Google around for mod_jk and glassfish and you should find some blogs about it.

Apache does'n propagate request information to OC4J

Hello,
We are successfuly using a great piece of code, modNTLM (sets REMOTE_USER request variable to "PRAHA\Kolek_R" for example), on our intranet server. We are implementing security on "LOCATION" container (see uncommented part of httpd.conf bellow). Everything works fine till time we tried to apply security on "remote" location. In other words security on "local" location only works fine.
So, the question is, how we have to setup apache to behave the same way in respect of "remote" locations ? The redirection to remote location we implemented through ProxyPass and ProxyPassReverse directives as You can see bellow in commented section. It works well except of discovering the username of incomming user. It can be seen in access.log file too.
Note that "remote" location is placed on our application server (OC4J) and apache serves as its frontend.
PLEASE FORGET THAT WE ARE USING NOT SUPPORTED APACHE MODULE (MODNTLM) AND PLEASE HELP US TO DISCOVER WHY APACHE (FRONTEND) DOES NOT PROPAGATE REQUEST INFORMATION TO APPLICATION SERVER (BACKEND).
Please help and & thanks in advance for Your time and answer,
Radim.

HTTPS mode for OC4J - Very Urgent

Hi,
I am trying to implement HTTPS mode with OC4J for our internal application. The Server Configuration and how I tried to implement is detailed below.
The Server Configuration :
Operating System     :     Linux 7.1
Java Development Kit     :     j2sdk1.3 with j2sse 1.0.3
Web Server          :     Oracle9iAS Containers for J2EE (OC4J) OC4J build# 020712.1645.
The command for generating the CSR (for test certificate from Entrust)
1. keytool -genkey -keyalg "RSA" -keystore keystore -storepass 123456 -keysize 512
2. keytool -certreq -keyalg "RSA" -file gisl-dev -keystore keystore
I had generated a CSR from the server and submitted the CSR online for a test certificate. On submission freecert.entrust.com had issued the web server certificate and the CA certificate successfully.
After this I tryed to import the Web Server Certificate with this command:
3. keytool -keystore -keyalg "RSA" -import -trustcacerts -file gisl-dev.cer
I am getting an error:
keytool error: java.security.cert.CertificateException: Unsupported encoding
Is there anyway to come out of this problem, I think I can use Apache Server and tunnel the request for OC4J through Apache. But the sad thing is that I don't know how do it.
Please help me out to solve this problem

1/ try to add a LF to your reply certicate. (there is a bug on keytool import)
2/ Also you need to check if your CA provider certicate is known on cacerts file. If not you need to import it.
Hope this help

Mod_orion for Apache?

Does anyone know if a mod_orion (or similar) is in the works somewhere to hook up Orion (or OC4J) to Apache?
John H.

As Philip Ross already said, Orion announced AJP13 support with version 1.4.8. Upto 1.5.2 this is disabled due to 'pending issues', but when it will be available, you can use mod_jk from tomcat3.3 to connect Apache and OC4j/Orion. This would provide a more efficient connection and access to parts of the request like certificates.
<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by John Haasbeek ([email protected]):
My interest stems from all of the other mod's I like to use in Apache (php, perl, etc) to supplement the Java stuff I build applications with. I must research this reference to AJPV13 protocol support, as that seems to imply that Orion could work with mod_jk, which would be rather nice. Thanks for the replies,

Deploying servlets (not in jar/war/ear!) to OC4J?

I must be missing some very tiny but crucial issue....
For over 2 days now (shame) I have been trying but not
succeeding to deploy servlets to OC4J behind Apache. The 'behind
Apache'-part is easy. Just set up a proxy. This is because
Apache configuration is easy and well documented. But here is my
real problem. I am using JDev 3.2 (9i too large) and this is
what I want:
I want to code a servlet in Jdeveloper, compile it to a class-
file, not a jar, war, ear or whatever-r. Then I want to set up
OC4J in such a way that I can access my servlets from the
directory where the class files are. I do NOT want to use the
default-web-app subdirectory for obvious reasons. Please, how do
I set up OC4J to just look in my own classes-directory with my
own servlets???? No jar, no war, no ear.
I have been reading all sorts of information on this and tried
everything, but am not succeeding and getting all sorts of
error/not found messages.
Extra info:
I am using OC4J on windows. To start I use java -jar orion.jar,
to restart I use ^C and repeat the start command. Is that ok or
do I need to restart in a different way? I tried to setup OC4J
as a service but the link to runexecsvc went astray to judosoft
Any help will be greatly appreciated!

Avi,
Thanks for your swift reply. I have indeed read the docs, but
the exploded directory format does not seem to work for one
reason or another (got some error messages on file not found or
something). Have you succeeded in deployment using exploded
directories? If so, I would be greatly interested in your xml-
files and directory structure!
But, please do not spend too much time on this, because I have
now decided that I will deploy using a war. I have written a
small script to make a war out of my whole project and copy it
to de OC4J file system. This works and everybody is happy.
Thanks again,
Martijn
