Thanks Tiboy.

Hi there,
I have another doubt. Im trying to deploy a web application/J2EE. I use JBOSS. Now, after compiling and placing my jar files in the required directory and as i start the JBOSS server I get the following error in the console............
10:11:06,551 WARN [jbossweb] java.lang.IllegalStateException: Servlet class
com
.ncit.user.server.servlet.MainPageRequestHandler is not a
javax.servlet.Servlet
java.lang.IllegalStateException: Servlet class
com.ncit.user.server.servlet.Main
PageRequestHandler is not a javax.servlet.Servlet
at
org.mortbay.jetty.servlet.ServletHolder.start(ServletHolder.java:203)
I just can't seem to figure out whats the problem.
My RequestHandler extends an Abstract Req.Handler which imports javax.* etc etc.
Please suggest a solution.
Thanks,
Tiboy.

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.

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.

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.

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.

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

Your help is highly appreciated.

Did 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.

What is there inside your jxl.jar.
Apache POI library name is poi-3.0.2-FINAL-20080204.jar in the last release available on [http://www.apache.org/dyn/closer.cgi/poi/]. Check your classpath, IMHO it doesn't contain any POI class.

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;

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.

Any ideas what causes Blocked trying to get lock: org.apache.log4j.spi ...

Hi, We are using WebLogic 9.2.2 with Java 1.5. The application is written using Struts 1.3 and log4j 1.2.15. We found a numbeer of errors that looked like below in our managed server's .out file. Any ideas what might be a cause or how to troubleshoot further? Our sys admin sadly did not preserve a thread dump:
<Jun 30, 2009 3:00:11 PM UTC> <Error> <WebLogicServer> <BEA-000337> <[STUCK] ExecuteThread: '148' for queue: 'weblogic.kernel.Default (self-tuning)' has been busy for "604" seconds working on the request "Http Request: /myapp/hhFlow.do", which is more than the configured time (StuckThreadMaxTime) of "600" seconds. Stack trace:
Thread-135888 "[STUCK] ExecuteThread: '148' for queue: 'weblogic.kernel.Default (self-tuning)'" <alive, in native, suspended, blocked, priority=1, DAEMON> {
