WLS logging api

Hi All,
My app is running on WLS 8.1. I am using WLS logging api to log the messages and
I also email those messages. I would like to configure the logging so that I can
send a particular message once every x time interval.
e.g. If the same error message is thrown multiple times in an hour, currently
the app will send those many emails. I want to change it so that even though the
same error message is thrown multiple times in an hour, the app will send only
one email.
Is there a way to do this using WLS api?
Thanks,
WD

I did not set up the email messages within WLS 8.1. I have written my own emailer
class that I use.

WLS logging/statistics

Hi!
I wonder whether there is possible to gather the continous information
one can view in the WebLogic Console for statistical purposes.
E.g. it could be valuable to view curves for connection pool usage,
memory usage, bean cache usage and so on.
Thanks for any comments on this topic :-)

Logging API

I am trying to use the logging APIs within a channel's java application code. The code will successfully create the log file, but I can not get it to log any information into that file. Can anyone point me to what I might be missing?
I am running Portal 6.0 on Solaris 2.9 with JVM version 1.3.1_04.
Here is the code I am working with, which is more or less right out of the developers guide. When I execute it i get no errors, no exceptions, no data in log file.
Any help would be appreciated.

      try {
            SSOTokenManager manager = SSOTokenManager.getInstance();
            token = manager.createSSOToken(req);
            if (!manager.isValidToken(token)) {
                    message = "*** InValid Token. ***";
      } catch(Exception e){
                    message = "*** SSOToken Exception. ***" + e.toString();
       try {
                  LogManager logger = new LogManager(token);
                  logger.create("SampleLog.log");
                  LogRecord lr = new LogRecord("Session", "Sample Data");
                  logger.write(lr, "SampleLog.log");
        } catch (Exception e) {
                      content.append( "Logging Error: " + e.toString() + "\n");

Thanks for your feedback.
BEA is on the expert group of this JSR and we are tracking this standard.
We will consider implementing this API in the next release.

Logging api hangs

Im starting a java application from an applet calling Runtime.getRuntime().exec("java bla bla bla")
Worked fine until I implemented Java 1.4 logging api. Now the application hangs after writing a few info lines to a FileHandler log. It's clearly the logger that hangs because if I set log level = OFF the the program runs just fine.
Has anyone seen anything similar?
* To make it harder to debug, the problem only occurs when starting the application from an applet.

That might happen that spawn process generates lots of output.
Runtime.getRuntime().exec() returns object of type java.lange.Process. That object provide access to the stdout and stderror of the newly created process. If those streams are not cleaned properly then process will hang as soon as OS buffers of those stdout and stderr streams get full.
One way to work around it just read output from the process and throw it away. You can try using something like this:
package com.xxx;
import java.io.InputStream;
public class ProcessOutputWaster {
    public ProcessOutputWaster(Process process)
        throws Exception {
        createWorker(process.getErrorStream()).start();
        createWorker(process.getInputStream()).start();
    protected Worker createWorker(InputStream is) {
        return new Worker(is);
    protected static class Worker
              extends Thread {
        private InputStream inputStream_;
        public Worker(InputStream inputStream) {
            inputStream_ = inputStream;
        public void run() {
            if (getInputStream() != null) {
                try {
                    byte[] buffer = new byte[1024];
                    int read;
                    while(true) {
                        read = inputStream_.read(buffer);
                        if (read < 0)
                           break;
                catch(Exception ex) {
                    Handle the error some how. E.g. show the error box.
Process process = Runtime.getRuntime().exec(strCommand);
ProcessOutputWaster outputWaster = new ProcessOutputWaster(process);

WLS logging - quick questions

Hi
In JDeveloper, we could write our application logging to logs for debugging and viewable from JDeveloper.
When we deploy to Standalone weblogic server, we cant find our logging.
Of the 3 loggers (Msg Catalog, nonCatalog, Commons log API),
Which logging mechanism is the best practice used logging for development environment ? Does it print to AdminServer.log ? If not, how can we accomplish that printing app log to AdminServer.log ?
Which logging mechanism is the best practice used logging for production environment ? Does it print to AdminServer.log ? If not, how can we accomplish that printing app log to AdminServer.log ?
Thanks

Practical use of Java Logging API

There was a recent technical tip about the Java Logging API, but after reading it I still don't understand how to use it in a real situation.
Can anyone help me with this with a practical example?
At the moment I have try-catch clauses that catch exceptions and print a message in a System.err log that I can consult if there's a specific problem.
How should I be using the Logging API? I feel sure that it can help me, but can't see how.
Thanks for any practical information.

What if you don't want to write to system.err anymore? What if you need to write something to the windows event log? What if system.err is irrelevant (nt service), ...
Btw, lots of examples on the JDK1.4 logging api:

How to set NC Log API

Hi all,
I want to use the following NC log API,but I don't know how to initialize the interface's java object and set the parameter "ApplicationVO".
Interface LogNCApplicationInterface
Method ApplicationVO addNDone(ApplicationVO applicationvo)
Please help me.Thank you!
Qiang Liu

if you just need to log an NC the minimum fields you need to set are the following:
CreateNCRequest ncRequest = new CreateNCRequest();
ncRequest.setActivity("NC500"); // activity where NC is logged - can be any name
ncRequest.setSfcRef(new SFCBOHandle(site, sfcParent).toString());// the SFC for which you are reporting an NC
// ncRequest.setValidateNCCodeOperation(true); // no need to set it, it's true by default
// nc code reference for nc code that is reported
// nc code must exist in the system
ncRequest.setNcCodeRef(new NCCodeBOHandle(site,"NCCODE").toString());
// required custom fields must be set
CreateNCResponse ncResponse = ncPSI.createNC(ncRequest);

Logging the Runtime Fault messages BPEL in WLS logs

Requirement: I need to capture the run time fault from BPEL processes in the WLS logs how to do this?
Solution: I have tried following I created the Java class ot initialise the Java logging.
Java snippet:
private static final Logger logger = Logger.getLogger("oracle.soa.Logger");
static {
LogFormatter.configFormatter(logger);
public static final void log(String message) {
logger.log(Level.INFO, message);
In my BPEL process I have the CatchAll activity
In the ‘AssignFault I’ have the assignments using ora: getFaultAsString() , but I’m not getting the expected fault in Assign Activity which we see in Audit Trail.
In Audit Trail i see the following message against the my Validate Activity
"Invalid data: The value for variable "ReceiveXML_Read_InputVariable", part "body" does not match the schema definition for this part Element 'TimeBandList' not expected.. The invalid xml document is shown below:"
The ora: getFaultAsString() is showing the "com.oracle.bpel.client.BPELFault: faultName: {{http://docs.oasis-open.org/wsbpel/2.0/process/executable}invalidVariables} messageType: {{http://schemas.oracle.com/bpel/extension}RuntimeFaultMessage}"

I had gone thru that documentation. I needed something more than that.
Well, I want to know what entries go into the access log & what into custom
log of ours.
Actually, the entries with 200 status only are going into our custom log ,
how can I make the entries with status 302 (redirection) to get into the
custom log?
Thanks.

Setting Logging API config file

Hi,
Is there a way I can set the Logging API's config file (java.util.logging.config.file) from within my program? I have tried using System.setProperty but it doesn't seem to work. The only way I seem to be able to set the property is with -D on the command line.

Logging API AdapterFramework 3.0

Hello,
i still wonder why it was necessary to provide an own API for Logging and Tracing inside the Adapter Framework.
The Web AS Logging API does the same.
Developing an JCA Adapter that can be used inside the XI Adapter Framework and as a Basic JCA 1.0 Adapter in the Web AS, theres's need to provide support for both APIs.
Has anyone an idea to solve this problem?

There is a lot of logging to the console with 2.3.0 RC1 when I am doing
any trips to the datastore, is it possible to switch this off? I am
using Kodo.rar in Jboss 3.0.0Remove the 'com.solarmetric.kodo.Logger' property from your properties file. You can also remove it from the Properties instance you use to construct the PersistenceManagerFactory. If you'd like to log to a file instead, change the property to the name of a file to log to.

Is this logging code faster than using a standard logging API like log4J

is this logging code faster than using a standard logging API like log4J or the logging API in java 1.4
As you can see my needs are extremely simple. write some stuff to text file and write some stuff to dos window.
I am thinking about using this with a multi threaded app. So all the threads ~ 200 will be using this simultaneously.

In general I'd guess that a small, custom thing will be faster than a large, generic thing with a lot of options. That is, unless the writer of the small program have done something stupid, og the writer of the large program have done something very smart.
One problem with java in this respect is that it is next to impossible to judge exactly how much machine-level processing a single java statement takes. Things like JIT compilers makes it even harder.
In the end, there is really only one way to find out: Test it.

Customize Java logging API

Want to customize java.util.logging api, like write message to message queue, xml file, etc. Would you guys give me some useful suggestion or resource or link? Thanks.

Just write a sub-class of Handler such as this:

}Look into the JDK source code such as MemoryHandler and StreamHandler on how to implement it.

How come logging is so hard? - JDK1.4 Logging API

Have a small project on hand. A standalone java program trigged by unix cron job and do some data cleaning. Need to implement a very simple logger. Tried to use JDK1.4 Logging API, here's my code:
public class MyLogManager {
     public final static String NAME = "mylog";
     public final static String LOG_FILE_NAME = "C:/my.log";
     private static Logger logger;
     static {
          try {
               logger = Logger.getLogger(NAME);
               Handler fh = new FileHandler(LOG_FILE_NAME);
               fh.setFormatter(new SimpleFormatter());
               logger.addHandler(fh);
               logger.setLevel(Level.ALL);
          } catch (Exception e) {
               System.out.println("Unable to initialize logger: " + e.toString());
               System.exit(1);
     public static Logger getLogger() {
          return logger;
and use MyLogManager.getLogger().info("message") to log message.
It works and my.log was generated with log message. However, the problem is everytime a new job (java myprogam ...) runs, it deletes the old log file and create a new one.
I want the message to be appended by the end of old log file. What should I do? Any help?

Use log4j (google for it - it's on http://jakarta.apache.org).
If log4j.jar is in your classpath, the JDK 1.4 logging framework will use it automatically. Then all you have to do is to configure a log4j.properties file in your classpath to log wherever you want it to.
And log4j is sorta-smart about multiple programs logging to the same file.

Jdk logging api

iam using jdk logging api. I've a scenario,
where there are two subclasses for a parent one.
is it suffice to use Logger.getLogger("packagename.superclass");
in the parent class, for all the subclasses to use the same logging medium.
