Log4J and OAS 10.1.2.0.2

Greetings, all!
I've searched this forum and the OC4J forum and have not found any clues to help with my log4j woes. I'm hoping someone may have encountered similar issues and can share their thoughts.
I am developing a web application and would like to use log4j. I have successfully integrated it in my development environment (JDev 10.1.2.1.0/Standalone OC4J 10.1.2.0.2) by placing the log4j jar (log4j-1.2.14) in WEB-INF/lib. I have not been successful in moving it to our staging OAS environment, however. We are running 10gR2 OAS (10.1.2.0.2) on Windows 2003.
Since I read in the docs (http://download-west.oracle.com/docs/cd/B14099_19/web.1012/b14017/jkosfram.htm#sthref698)that the log4j jar should not be put in the applib directory of the OAS_HOME I have been trying to deploy the application with the jar file within the WEB-INF/lib location. Every time I try to deploy, I get the following error complaining that it cannot find the correct classes.
Base Exception:
com.evermind.server.rmi.OrionRemoteException
Class not found: org.apache.commons.logging.LogConfigurationException; nested exception is:
java.lang.ClassNotFoundException: org.apache.commons.logging.LogConfigurationException. Class not found: org.apache.commons.logging.LogConfigurationException; nested exception is:
java.lang.ClassNotFoundException: org.apache.commons.logging.LogConfigurationException
I understand it is probably a classloader issue, but using an orion-web.xml file with the search-local-classes-first set to true does not work either. I was successful in deploying the app and writing to a log when the log4j jar was in the applib directory, but since the docs state that this could cause conflicts with OEM, I removed the jar. I have also been able to log to the application.log file by using context.log() statements, but this is less than optimal.
I know 10.1.3 may solve this issue, but we are not planning on that version for some time. How are others using log4j in the OAS? Should I just place the jar in the applib and hope for the best?
TIA for any help or insight,
Dixie.

I resolved the problem and wanted to post the solution in case anyone had similar problems. The issue was related to the commons.logging package used by JSF. I had version 1.0.4 in the applib directory of the OAS_HOME along with the other jars needed for JSF. Once I upgraded to the 1.1 version of commons-logging I was able to deploy the app and use log4j. I received this metalink reference from a colleague and it helped me solve the problem: Note:413981.1

BC4J and OAS with Java Application Client

Could you show me an example about using the BC4J and OAS with Java Application client.
The JDeveloper Help is not enough to solve this kind of problem.
Configuration:
Jdeveloper 3.1
OAS 4.0.8.1
Database 7.3.4
null

if you can logon with client tools then that should be an indication that the service account running the CMS IS working! Good news.
So the problem is likely with the java portion (krb5/bsclogin or java options)
If the files are in c:\winnt\ (if not copy them there) and perform c:\program files\business objects\javasdk\bin\kinit username
then enter and password/enter again
Probably get the same message. To note in your krb5.ini all domain info must be in CAPS (the .com appears to be in lower case)
kinit works with just the krb5.ini, java SDK and AD (removing BO config and the service account from the picture). Once that works if your java options are specified properly you should be able to login to CMC/infoview.
also 1 last point. Add udp_preference_limit = 1 to the krb5 lib defaults section
libdefaults
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
udp_preference_limit = 1

PDF printing with APEX version 3.2.1 and OAS 10.1.2.3

Hello,
Is it possible to print PDF's with APEX version 3.2.1 and OAS 10.1.2.3? (Not using freeware- that'll never fly with my company).
Thanks!

JasperReports will do this and there is an integration toolkit out there for it and APEX.
BI Publisher is available, and costly
Oracle Reports can do this and is still available..
One question, why would your company shy away from open source software like Cocoon/FOP? It comes with APEX 3.2 as an installable WAR and if you use the APEX listener, it comes with that for FREE!!
Thank you,

Log4j and log4cxx together

Hi,
I'm using RollingFileAppender to append log4j and log4cxx logs in a common log file. This works only for the first log file. But, the subsequent log files which got created when the size exceeds the specified range, does not getting appended the log4cxx logs.
I have referred http://www.dreamcubes.com/blog/?itemid=59#nucleus_cf

Logger experts,
First of all, trying to point a common logging file from two different log configuration file is possible?
If this is not at all possible, Keeping the two different log file would work, but it is cumbersome on debugging..
Thanks and Regards,

Log4j and WAS logging

Hello all,
Is there anyway to redirect log4j logging to WAS loggers.
For example, axis needs log4j and may need to log to some appenders.
Can we safely use SAP logging and how?
Is there an example somewhere?
Antoine

There's an article "Integrating 3rd party logging Frameworks into SAP NetWeaver" (https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/36085e78-0801-0010-678d-8b4e89ddff3c)
It mentions sample code and a tutorial for a "Log4j bridge", but I couldn't locate that. I have posted a separate question for that.
Hope this helps,
Michael

Log4j and Jboss are acting weird

This question is reagards to Log4j and JBoss and I thought this is the best place to ask this question.
I am using Jboss 3.2.3. My purpose was to log messages in a seperate file "developer.log" using Log4j. These messages has to be logged in this file only. So in my WAR's folder under WEB-INF/classes I created a file log4j.properties:
log4j.logger.standard=DEBUG, devlog
log4j.appender.devlog=org.apache.log4j.RollingFileAppender
log4j.appender.devlog.File=C:/logs/developer.log
log4j.appender.devlog.layout=org.apache.log4j.PatternLayout
log4j.appender.devlog.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%nNow my code :
import org.apache.log4j.Logger;
private static Logger log = Logger.getLogger("standard");
log.debug("a debug message");
log.info("a info message");
log.warn("a war message");I test run this code without Jboss and it works perfect. It created a file "developer.log" in the desired location and logs messages in it.
Now i run with JBoss. JBoss does not create "developer.log" file at all. Instead it logs all the messages in server.log
2005-09-30 23:07:35,459 DEBUG [standard] a debug message
Jboss is recognizing that it is standard but after that it is not gving me the desired results. Any input on how to fix this problem?
TIA

You can tell it you don't want to inherit, by adding
this to your "standard" category tag:
<category name="standard" additivity="false">
thanks. it works perfect.
ok i got it working kind of. Jboss already comeswith
a log4j.xml so i put my log4j stuff in this file :You should be able to deploy your own log4j.xml with
your app's resource files and make it use yours when
it is running your app.Ok I took out my stuff from Jboss log4j.xml, create a new xml progtest.log4j.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">
<appender name="DEVLOG" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="${jboss.server.home.dir}/log/developer.log" />
    <param name="Append" value="true" />
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d{ABSOLUTE} %5p %c{1}:%L - %m%n" />
    </layout>
</appender>
<category name="standard" additivity="false">
    <priority value="INFO"/>
    <appender-ref ref="DEVLOG" />
</category>
</log4j:configuration>My web application is in a ProgTest.WAR folder. I put the above file "progtest.log4j.xml" under WEB-INF/classes in ProgTest.WAR folder. When i run the app the very first problem again arises that no developer.log file was created; instead the concerned messages were put into server.log and console.
All my classes are in one jar file. I include progtest.log4j.xml in that jar file, redeploy it and test it but still the same problem.
What i am doing wrong here?
Thanks

Log4J and LogConfigurationException...

I get an error when I try to deploy an old application to the newly updated Oracle Application Server 10.1.3. It has something to do with Log4J, and I've tried a lot of different things, but nothing seems to help.

Request failover between Load Balancer and OAS 10.1.3.3

Hello,
I have a Load Balancer hardware "Cisco 11500 content service"
Working on 4 applications server OAS 10.1.3.3 on the oracle enterprise lunix
We are using Oracle HTTP Server And deployed application Under (j2ee) I am using Cluster between them "instant” as the same on all 4 servers
If an OC4J process goes down between requests, then this module is able to hide that failure from the end user by transparently routing the next request to another OC4J that is available within the same group of JVM.
BUT when I shutdown the opmn the Load Balancer Hardware is still sending that requests to the opmn that is already down
How can I configure or fix that request that is common to that opmn stopped process
Do you have the solution to solve this issue?
Thanks.
Regards.

Dear All,
Will appreciate if someone can answer this. Please let me know.........

Log4j and Tomcat-problem

Hi all,
First I tried to add some logging to my simple Java code with a xml configuration file and it worked fine.
Now I am trying to add logging to the whole java application in the same way which runs in tomcat and face with the foll problem.Tomcat is not able to find the configuration file.I tried to place the xml file in all feasible locations in tomcat and also tried to add in classpath but in vain.

DOMConfigurator.configure("sudarson.xml");//**********its telling it cant find/open this xml fileWhat does "sudarson.xml" mean to you? To me, it means a file name relative to the current directory. What do you think the current directory is when you're running this in Tomcat?
You need to research the APIs more fully, to figure out how to give it a resource name relative to the application's classpath, and put that file in said classpath.
If I were you, I would try to avoid explicitly calling DOMConfigurator.configure altogether, and just pass the appropriate Log4J system property to the commandline that starts up Tomcat. Let Log4J worry about loading the file, given the property. If I recall correctly, the system property name is "log4j.configuration", which defaults to "log4j.properties" if unspecified. Also, rather than have each application running in Tomcat have their own log4j configuration file name, I'd name them something more universal, like "log4j.xml" - then if you deploy multiple apps in Tomcat, they can all load their own log4j.xml file, as long as (again) you corrected the "log4j.configuration" system property.

Reports Graphics and OAS 10g

I made a report with a pie char in developer 10g, it runs OK and i see the char in my desktop. When I execute the report (.rep) in OAS 10g (Forms a Reports Services) via the rwservlet, the resulting PDF file contains everything but the chart doesn't appears (white page). Is there any kind of configuration I need to adjust?

Hi,
This is strange. There is no additional configuration needed for charts. If your reports are running fine, it means you should be able to get charts in the output. Does the same problem reproduce if you change the output format from PDF to HTML or HTMLCSS?

Oracle 8i Stored Java Procedure and OAS 4.0.8

Hi,
I'd like to call a Java Stored Procedure
from the OAS, like an ordinary PL/SQL
package. The Java Stored Procedure should
generate HTML-code to display in the browser.
My first try was, to use the
SQL wrapper function and the PL/SQL cartridge
of the OAS, but unfortunately, I always
get an "Request failed" with the error
number 20001 (user defined error).
Does anybody has managed to do this?
Thanks,
Thorsten.

Please read the Jdeveloper release Notes...
There is no version of Jdeveloper certified to deploy to OAS 4.0.8.2.

Oracle ADF and OAS licencing

Hi all,
I have been doing a research on JSF component, ADF and ADF Faces for our project. I have found some intresting things that
ADF faces(donated to Apache by Oracle) is free but it is only for front end (not complete) as of ADF.
ADF is more promising and good frame work. ADF is free to be deployed on OAS. but i am unable to find pricing for Oracle Application Server is it free ?.. and what is the price for Deploying ADF on Tomcat or other Open source Servers...?.Can i get this information I need it urgently. Thanks..

Hi,
the Oracle AS licence depends on the edition you want to use. I suggest to get in touch with a local sales office to get the pricing information.
ADF Faces / ADF deployed to 3rd party servers has a licence cost of 5k USD per CPU (at least this is my latest information. So you better check this too)

Query ON ORACLE AND OAS UPGRADE PLAN

Currently we are running Oracle Server 7.3.4 Under Unix (SunOS5.7) with access to a Sybase 12.5.0.1 via Oracle-Sybase Transparent Gateway 4.1.1.0.0.
For the web services, we use OAS 4.0.8.1. Our web applications are based on Javascript and Oracle PL/SQL to generate HTML.
We plan to upgrade the Oracle Server from 7.3.4 to Oracle 9iAS version 9.2.0.1.
Our quetions are :
1) Is it necessary to upgrade OAS 4.0.8.1 to Oracle 9iAS?
1a)If we have to upgrade then which version of 9iAS (9.0.2, 9.0.3, 9.0.4)is compatible?
1b)what change, if any, do we have to make to our exisiting applications(Javascript, HTML and PL/SQL-generated HTML) (we understand that the application logic would not have to be change in any
way. Is this so?)
2) Are Oracle Server 9i and Oracle 9iAS Application Server compatible with the SunOS5.7 Unix or is an upgrade to a later version necessary?
3) Do we need to upgrade the Oracle-Sybase Transparent Gateway if we upgrade the Oracle Server to Oracle9i and if so, to what version?
Please confirm that Oracle9.2 has a Gateway to Sybase 12.5.0.1 that will support the features of 7.3.4 gateway (i.e it is downward compatible to 7.3.4
gateway).

Not real sure if this is doable or would help, but perhaps you can load the access table into an Oracle Global Temporary Table? See http://www.oracle-base.com/articles/8i/TemporaryTables.php (and google on it). I think I'm assuming your 11 hour query had something to do with shovelling a bucketload of data to the access side, perhaps if you could show us the plan on the Oracle side that access was generating to get the Oracle data there might be a different answer.
Oftentimes cross-db tools won't use Oracle features like analytics, or do slow-by-slow row processing where a short procedure could do things within the Oracle sql engine and return data in larger arrays.
Sometimes mass data cleansings benefit from using server side tools outside of the db. Do you have the data from before it was loaded to Oracle? What Oracle platform are you on?

OEM 10.1.0.3 and OAS 10.1.3

Hi all,
I have a server with Oracle Enterprise Manager 10 Grid Control Release 1 (10.1.0.3) and a server with Oracle Application Server 10g Release 3 (10.1.3.0.0). Is it possible to add the OAS as a target in the OEM?
I tried to install the agent 10.1.0.3 in the OAS server, and the OEM server found the agent, but it seems that the agent did not found the OAS 10.1.3 version.
Could the installation of the last OEM Agent version (10.2) in the OAS server resolve the problem? Or I need to install the last version of OEM Grid Control in the OEM server?
Thanks in advance,
André Panisson

When you go through the Installation pre-requisites and Release notes before installation 9which helps a lot), it lists compartible Managed Targets etc. So, it will be advisable (even if you have not resolved your problem) to go through it for future knowledge.
