I am successfully logging with GAE. See: Logging

To view the log, you have to go to the admin console See: Admin Console Select Main >> Logs.

Be sure you have a logging.properties file in the location you specified in the appengine-web.xml file. The entries in this file determine what is logged. See: logging.properties example

You don't need a Google Apps domain name. Access the Admin Console (and Logs) at: http://appengine.google.com/a/anctdb

It is my experience that local logs are output in the (Eclipse) System console prefixed by INFO, WARNING, SEVERE, etc.

java.util.Logger

Do you see output in your system console when running your app?

1. Make sure your app can see the logging.properties file. Note: The default property in appengine.web.xml was incorrect when I installed the plugin. Use the following property declaration:



2. Make sure you have a file named logging.properties in WEB-INF/classes that contains (at a minimum):

Hi,

I dont get the log in my console of eclipse..just it shows the lines below:


datanucleusenhance:
[enhance] DataNucleus Enhancer (version 1.1.0) : Enhancement of classes
[enhance] DataNucleus Enhancer completed with success for 0 classes. Timings : input=141 ms, enhance=0 ms, total=141 ms. Consult the log for full details
[enhance] DataNucleus Enhancer completed and no classes were enhanced. Consult the log for full details
runserver:
[java] The server is running at http://localhost:8080/


I already configured as you said.Still pointing logging.properties in WEB-INF/classes.

I am not sure what to tell you. Configuring the appengine-web.xml and logging.properties file are the keys. If logging is not working, then most likely something is wrong with one of these files. When configured correctly and logging on a development server, you will see output similar to the following in the system console:



Notes:
1. Instance.Log is a wrapper around the logging mechanism.
2. An informational message is displayed because the specific servlet is configure to display INFO messages. e.g.

Iam using Struts FrameWork.Is it not working because of Struts?


in my logging.properties file i mentioned like

# Set the default logging level for all loggers to WARNING
.level = WARNING
com.web.struts.StrutsAction.level=INFO

I have no idea. My recommendation would be to create a separate, small project that does not use Struts. If logging works, then it is a Struts issue. If it is a Struts issue, I would post a query with Google App Engine for Java group. I cannot help you if it is a Struts issue.

Hi jay,

Using Struts:

I cant get logs in any manner and also i tried for setting an attribute in HttpServletRequest,But i cannot get the same attribute using request.getAttribute().

Without Struts:

I can get my application logs and also able to set and get Attributes in HttpServletRequest object.

Whats the Solution for this Jay?

Re Struts: I don't know. I don't use Struts. You are on your own if you choose to use Struts. My best suggestion would be to post to Google App Engine for Java group.
 
It is sorta covered in the JavaRanch Style Guide.
