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 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
RanjanThose 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. -

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
Wrote EAR file to C:\shobz\SOFTWARES\otm_jdev_10G\jdev\mywork\TestADF\UserInterface\deploy\webapp1.ear

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,

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,
RickThe 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.

Truncated. see log file for complete stacktraceDid you read this part there:
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,

Cannot import package org.apache.catalina in Tomcat 4.1
Hi,
Don't know why I cannot import org.apache.catalina.realm.RealmBase.*; or org.apache.catalina.*; but no problem in importing org.apache.*; ?
error prompts "package org.apache.catalina.realm.RealmBase does not exist " Thanks.
JackieYes, I can find org.apache.catalina.jar in /lib but why my jsp program cannot locate this class? Something wrong with my web.xml / server.xml? Thank you.

Help to solve problem with packaging log4j in a EAR file
Hi All
i struggle hard to create a EAR composed of EJB JARs and WARs and the programs
in these JARs and WARs use log4j to log msg. Because i want all J2EE apps to have
their own version of log4j library, i package log4j.jar in the EAR file. Below
is my EAR package structure
EJB1.jar
EJB2.jar
SharedUtilities.jar
log4j.jar
log4j.properties
WEBAPP1.war
WEBAPP2.war
META-INF/manifest.mf
For both EJB1.jar and EJB2.jar's META-INF/manifest.mf, there is a below entries
Manifest-Version: 1.0
Class-Path: SharedUtilities.jar log4j.jar
However, my program always hit below runtime error.
[java] Caused by: javax.ejb.TransactionRolledbackLocalException: EJB Exception:
: java.lang.NoClassDefFoundError: org/apache/log4j/PropertyConfigurator
But the program in EJB1.jar and EJB2.jar seem to have no such problem in loading
classes in SharedUtilities.jar. The problem can be eliminated if i put log4j.jar
at system classpath. Can anybody provide me with info on how to package a log4j
library within a EAR package ?
In addition, where should i put the log4j.properties so that it will be at search
path of log4j and automatically loaded by log4j lib
regards
DannyHi Slava Imeshev
I am a bit confused about your reply. As said, the log4j.jar was packaged in my
ear file. If the log4j.jar was not packaged in ear file, how come the ejb classloader
can locate it.
Secondly, if log4j.jar is included in system classpath, the ejb also can load
log4j classes by system classloader. No "NoClassDeffound" exception is thrown.

Hi Slava Imeshev
thanks for your response. I am a bit confused about your answer.
i can't understand why u said the classloader COULD loadorg/apache/log4j/PropertyConfigurator.
According to the error msg, it said
" java.lang.NoClassDefFoundError: org/apache/log4j/PropertyConfigurator".
Seemingly,
this class in log4j.jar could not be located. But as i said in lastquestion,
i seemed to have properly
edit the "META-INF/manifest.mf" in EJB1.jar and EJB2.jar to includelog4j.jar
in "Class-path" attribute. And my EJB classes have no problem in loadingclasses
in SharedUtilities.jar. Would u please elaborate on it in more details?
Sure. NoClassDefFoundError means that a DEPENDING class
can not be loaded. If the classloader were not able to load the class
itself, it would give you ClassNotFoundException.
Just make sure that you don't have the same packages in
the ear and in the class path so that you don't have classes
loaded by system classloader trying to load classes loaded
by ejb classloaders.

First, this error means that classloader was able to load
org/apache/log4j/PropertyConfigurator, but cold not load
one of depending classes. I'd inspect the CLASSPATH
to see if there are any log4 classes there.
Second, you can package your log4.properties into
log4.jar itself.

The import org.apache cannot be resolved
Hi All,
I am a Java\Eclipse newbie. I am trying to import the org.apache.xerces package, and the import is failing with this error:The import org.apache cannot be resolved
I am not using Maven\Ant for building the project. I know I need to download some class files\jar files to get this to work, but I am not sure where to download these packages from. Could someone please help me out here?
import org.w3c.dom.Node;
import org.apache.xerces.parsers.DOMParser;
import org.apache.xerces.dom.traversal.TreeWalkerImpl;
import org.apache.xerces.domx.traversal.NodeFilter;
import org.apache.xerces.dom.DocumentImpl;
THanks a lot!Well, if you are in fact looking to download the JARs for the Apache Xerces project, you should be able to find them at the Apache Xerces project page.
If you already have the JARs downloaded, you need to make sure that they appear on your CLASSPATH, otherwise your application will never find them. Since you are using an IDE, this should be as easy as adding the JARs to your project.
