Re: Logs from different web apps go to same file with log4j?!

[G.Cholakov]

Hi Jake,

log4j.jar is in WEB-INF/lib, log4j.xml is in WEB-INF/classes. 
What do you mean by "use autoconfiguration or
some other location and use manual confguration"?

I attached the log4j.xml, because in the first post some lines dissapeared.

[Jacob Kjome]

Where do you place log4j.jar?  In WEB-INF/lib or in some shared location?  And
where do you place log4j.xml?  In WEB-INF/classes and use autoconfiguration or
some other location and use manual confguration?

The SMTPAppender has a configurable string property that specifies the protocol 
to be used and which is passed down to the java.mail API.  The value "smtps" 
has no special meaning to log4j, but does to java.mail and would result in use 
of an SMTP+SSL transport.   As the value is passed through log4j to the lower 
level API without special treatment, log4j is not specifically designed to use 
encryption.  We are just we are aware it can happen with some values.  In the 
same manner, if any FileAppender is configured to use a encrypted filesystem, 
the underlying system will perform encryption.

Not that I'm aware of.  The log4j extras companion (distributed separately from 
log4j 1.2.x), does call the Java API for Gzip and Zip compression of log files.

ECCN Question -- Apache Log4J 1.2

[Erin Clark]

Hi All:



I'm assisting a client with the export classification of their product
and the subject product utilizes Apache Log4J 1.2.  Do you know who
might be the correct developer(s) for this open source code?  If it's
you all, do you happen to know what the Export Control Classification
Number (ECCN) for this code?  If you don't know the ECCN, can you please
respond to the following questions at your convenience?

 

a. Does the code perform cryptographic functions (i.e.,
encryption/decryption)?

b.Does the code contain any cryptographic algorithms (i.e., 3DES,
Diffie-Helman, Blowfish, Rijndael, RC4, RSA) (whether or not these
algorithms are actually being used by the software)?

c. Is the code capable of interfacing with, calling to, using,
invoking or enabling/disabling the cryptographic features within other
software or within the underlying platform in any way?

d.Is the code capable of performing message digesting/hashing (i.e.,
MD5, RIPEMD, SHA, Tiger), fixed data compression or authentication?

e. Does the code contain/utilize and open cryptographic interface
(OCI), where the cryptographic capabilities of the code are
user-accessible and/or modifiable?  (See below for a more detailed
definition of OCI.)  

 

If 'yes' to any of the above, please provide detailed response.

(Open cryptographic interface - A mechanism which is designed to allow a
customer or other party to insert cryptographic functionality without
the intervention, help or assistance of the manufacturer or its agents
(i.e., manufacturer's signing of cryptographic code or proprietary
interfaces). If the cryptographic interface implements a fixed set of
cryptographic algorithms, key lengths or key exchange management
systems, that cannot be changed, it will not be considered an "open"
cryptographic interface. All general application programming interfaces
(i.e., those that accept either a cryptographic or non-cryptographic
interface, but do not themselves maintain any cryptographic
functionality) will not be considered "open" cryptographic interfaces
either.)

Please let me know if you have any questions for me and many thanks in
advance for your assistance.

Logs from different web apps go to same file with log4j?!

[G.Cholakov]

Hi,

The problem is the following - I have several web apps, running in Tomcat 6.
I've noticed that all logs go to one file, which is specific for only one of
the web applications! Each file in each application is named unique.
What I did wrong?

Here is the log4j.xml:

Re: Doubt about log4j configuration and OCI

[Douglas E Wegscheid]

I don't think you can load the Oracle native driver more than once (that 
tries to load the native bits/dlls more than once, and that's what the 
"Native Library already loaded" is about).

A couple of choices are to try to use the existing DataSource (which I 
don't think JDBCAppender can do out of the box, though I'd be surprised if 
no one has fixed that), or trying to leave the driverClassName off (if 
possible) so that you rely on the driver that was loaded earlier. (That's 
assuming the log4j appender is the later of the two to load, and that the 
JDBCAppender will let you leave off the "driver" parameter).

Doubt about log4j configuration and OCI

[Exposito Aguilera, Francisco]

Hello,

I have a doubt about how to configure log4j in order to avoid the error 

java.lang.UnsatisfiedLinkError: Native Library
C:\oracle\product\10.2.0\client_1\BIN\ocijdbc10.dll already loaded in
another classloader

I want log write the log in the same database as the other sql statements I
need for my application.


I have a DAO Connection class with this method:

public static Connection getConnection()
{
InitialContext initContext = new InitialContext();
Context envContext  = (Context)
initContext.lookup("java:/comp/env");
DataSource dataSource = (DataSource)
envContext.lookup("jdbc/testdb");
return dataSource.getConnection();
}

This method uses the DB info placed in META-INF/context.xml file:




Then I have my log4j.xml files configured like that:

   
   

   







But when I execute the first log.debug statement (the connection class has
been already executed), I receive the error

java.lang.UnsatisfiedLinkError: Native Library
C:\oracle\product\10.2.0\client_1\BIN\ocijdbc10.dll already loaded in
another classloader

Any idea?

Thanks in advance.
