Org/apache/log4j/Category on OAS 10.1.3 and Jdev 10.1.3.5

Hi,
I am new to ADF and my company is also new to ADF. We are doing how it coudl help us in acclerating the development of custom screens on top of OTM 5.5
I am using OAS 10.1.3. I am getting org/apache/log4j/Category error at the time of deployment causing road block. Plz help...
Below are the steps I followed
1. Stopped OAS
2. Install ADF Installer 10.1.3.5 by extracting files, changing adfinstaller.properties, and running java -jar runinstaller.jar adfinstaller.properties
3. Started OAS
4. OAS never started up as server.xml had an new entry
<application name="datatags" path="../../../BC4J/redist/datatags.ear" start="true" />
<import-shared-library name="oracle.ws.jaxrpc"/>
5. datatags directory was malformed in the sense META-INF/application.xml and other .xml file was not created at all.
6. Since ADF requires only libraries to be available, I removed this 2 enteries and started up the OAS.
7. Started the OAS
8. Copied files from
[$Jdeveloper Home]\jakarta-taglibs
to
[$OC4J Home]\BC4J\lib
the files are:
commons-digester.jar
commons-logging.jar
commons-collections.jar
9. Download and copy apache-log4j-1.2.15 (log4j-1.2.15.jar) to [$OC4J Home]\BC4J\lib
10. I created a simpel ADF Helloworld page.
11.Created a deployment discriptor orion-application and added the following enteries
<imported-shared-libraries>
<remove-inherited name="apache.commons.logging"></remove-inherited>
</imported-shared-libraries>
12. I right clicked on my UserInterface ->New-> Deployment profile -> Created a WAR file
13. Right click the WAR file and deployed to the OAS
14. I got the following deployment error

Your help is highly appreciated.

ADF 11g requires JEE 5.0 server.
Oracle Application Server 10.1.3 supports J2EE 1.4.
JDeveloper 11g application won't run on OAS 10.1.3.

Org/apache/log4j/Category

Hi,
When I try to run a client problem by using
log4j. It gives me the folllowing error:
java.lang.NoClassDefFoundError: org/apache/log4j/Category
at java.lang.Class.newInstance0(Native Method)
at java.lang.Class.newInstance(Class.java:237)
I am wondering if the above class is still included in log4j-1.2.8.jar
thanks,
Rick

The long answer is, look for yourself. You can look into a jar file with any zip utility program (e.g. Winzip if you are working on Windows). However it happens that I have that jar file on my system and the short answer is, yes.

Import classes like org.apache.log4j.*

Dear All,
I am studying some programs which use XML parsers in Java to read and write data in XML format.
I am unable to compile the main program as I am unable to import library
org.apache.log4j.Category and org.apache.log4j.PropertyConfigurator
I have downloaded the entire XML pack from your site and unzipped each jar. Many classes have been identified except the ones above.
Please tell me how to get around solving this problem.
Thanks
Ranjan

Those classes are part of jakarta log4J, not the Java XML pack.
You will need to visit http://jakarta.apache.org/log4j/docs/index.html and install log4j to compile/run that program. Or have you already installed it and successfully imported org.apache.log4j.*?
Hope that helps.

How to configue plugins for java like org.apache.log4j.Logger

My application tries to import org.apache.log4j.Logger ,import org.apache.commons.lang.StringUtils
and many such packages of org.
I got downloaded Logger package but could not figue it out how to configure it so that application can find it out through org.apache.log4j.Logger etc directory structure , because the installation instructions they gave there seems to create different directory structure.
Also is there any place where I can get the all packages of org group and cnfiguration tips for them.
Thanks & Regards,

Import problem org.apache.log4j.PropertyConfigurator

Sorry if this is a dumb question but:-
I have entered
import org.apache.log4j.PropertyConfigurator;
into NB5.5 and it says "package org.apache.log4j does not exist".
Am I supposed to download this package or is it on my PCs hard disk somewhere? I've done a file search but failed to find it. Does it come with JDE or JDK? or have I not set up a CLASSPATH variable/parameter?
Please can someone help?
Drew

First check whether you have log4j libraries on your machine.
By Default its not available with JRE or JDK.
If you dont find locally, download it from the apache site.

Import org.apache.log4j.Level;

Cannot Resolve Symbol
symbol : class Level
location: package log4j
import org.apache.log4j.Level;
Can anyone suggest something.
Thanks Tiboy.

There is a second possible issue that is specific to the commons-logging and related libraries when used with Integrated WLS and the configuration (which includes ADF) out-of-the-box. Because the commons-logging.jar is apparently in the system classpath, due to the way Java classloader delegation works, any log4j classes at the web application level are not visible to the logger factory by default. As long as this is the case, you may need to add the following to your web-application's WEB-INF/weblogic.xml:
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
What this does is tell the WLS JSP servlet to let web application classes override classes found in the system classloader. Standard Java classloader delegation gives the highest priority to the system classes.

Serializing org.apache.log4j.Level

Hi,
I'm working with Log4j and I have to serialize an org.apache.log4j.Level that has not an empty constructor but only more static instaces.
Is there a workaround to do this ?
Or How can I use the static instance ?
Thanks,
Bye Luigia

this is my XML file
<java version="1.5.0_08" class="java.beans.XMLDecoder">
<object class="org.apache.log4j.net.SyslogAppender">
<void property="name">
<string>my.syslog</string>
</void>
<void property="SyslogHost">
<string>localhost</string>
</void>
<void property="Facility">
<string>local0</string>
</void>
How can I specify the "Threshold" Property of the SyslogAppender at "INFO" or int value?
The threshold is a org.apache.log4j.Level.

Hi,
        Now I understood the problem and it is related to the dependency jar files. For running my custom actions I have the
dependency of 2 jar files . One is sqljdbc.jar and second is xalan.jar. sqljdbc.jar I have added in the following way. Can anyone tell me how can I add the xalan.jar in catalog.xml file
<?xml version="1.0" encoding="UTF-8"?>
<ComponentCatalog >
     <Category Name="My Functions" Description="My Custom Objects">
          <Component Type="Action" Name="XAController12" Description="" Label="XA Controller" ClassName="com.my.xacute.actions.XAController12" AssemblyName="my.jar" Dependencies="sqljdbc.jar"/>

Apache log4j

I need to use logger in my application.
Can anyone give me some ideas how to start.Small introduction will be good and sufficient.
Is apache log4j good or the java.logger?

The core of Apache log4j is the log4j.properties file which you can download from different sites.
This file defines the various way of logging the messages.
After placing this file in the folder where you have the java classes,you need to have the log4j.jar file which provides the API related to this logger.
Then on any java file u can log the message using the logger object.
Ex: Logger log=Logger.getRootLogger();
log.warn("this is warining message");
log.info("this is info message");
Depending on the appender specified on the log4j.properties the log may be displayed on the console or may be printed on the specified file.
Here is the part of log4j.properties file:
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout
#log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.rootLogger=info, stdout
I think this will help you a lot!

Eclipse won't resolve org.apache.* packages

Hello everyone,
I'm relatively new to java and eclipse and I am really stuck trying to use various packages.
First a little history on what I am doing. I've created a project from existing source using the new java project wizard. This source code is obtained from the Book: XML and Java: Developing Web Applications, 2nd Edition. It's sort of dated. It uses SDK 1.3, and xerces 1.4.3 the current is 2.9.1. I have version 2.9.0 according to the Eclipse plugin registry. ( Thought I'd mention this in the event it may be relevant ).
The problem is Eclipse will not resolve this line of code:
import org.apache.xerces.parsers.DOMParser;
I look at plugins and I see xerces listed:
Provider:: eclipse.org
Plug-in Name:: Apache Xerces-J
Version:: 2.9.0v200909240008
Plug-in ID:: org.appache.xerces
However, Eclipse content assist does not list any org.apache packages and of course it won't compile without fatal errors.
In an attempt to correct the problem I've created a classpath variable in
Preferences > Java > Buildpath > Classpath variables:: xerces_2_9_0 - /Applicatins/Eclipse/plugins/org.apache.xerces_2.9.0.v200909240008.jar
Then added the var to a launch configuration.
The same error still persists::
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
DOMParser cannot be resolved to a type
DOMParser cannot be resolved to a type
at chap02.SimpleParse.main(SimpleParse.java:20)
I've also tried to add jar's to the libraries using Preferences > Java > Build Path > User Libraries but the the button on the right 'Add jars...' is not acitve.
The complete source code is listed below. Although I don't think the problem resides there.
Anyone who can help me in understanding this problem and resolving it would be greatly appreciated.
( I obviously am misunderstanding something ).
Regards,
gjames
package chap02;
* SimpleParse.java
import org.w3c.dom.Document;
import org.apache.xerces.parsers.DOMParser;
import org.xml.sax.SAXException;
import java.io.IOException;
public class SimpleParse {
public static void main(String[] argv) {
if (argv.length != 1) {
System.err.println(
"Usage: java chap02.SimpleParse <filename>");
System.exit(1);
try {
// Creates a parser object
DOMParser parser = new DOMParser();
// Parses an XML Document
parser.parse(argv[0]);
// Gets a Document object
Document doc = parser.getDocument();
// Does something
} catch (SAXException se) {
System.out.println("Parser error found: "
+se.getMessage());
System.exit(1);
} catch (IOException ioe) {
System.out.println("IO error found: "
+ ioe.getMessage());
System.exit(1);
}

2) You will be better off figuring how to do that in Ant or from the command line, rather than an IDE.
3) When posting code, code snippets, HTML/XML or input/output, please use the code tags. The code tags protect the indentation and formatting of the sample. To use the code tags, select the sample and click the CODE button.
4) For best help on Eclipse, see the [Eclipse forums|http://www.eclipse.org/forums/].
