Hi All,

I am new to both glassfish and log4j.
I used to use eclipse ,tomcat and log4j together and every thing was fine
the logs appeared in eclipse console
I did that by following instructions in this file
# HOW TO USE LOG4J WITHIN ECLIPSE IN 10 MINUTES # by Daniel Gonzalez Gasull gasull[at]gmail[dot]com # # 1) Download log4j http://logging.apache.org/site/binindex.cgi # 2) Unpack the .zip file in your Java folder (In Windows it is usually # C:\Program Files\Java\) # 3) In Eclipse: Window - Preferences... - Java - Build Path - User Libraries - # New - write "log4j" - OK - Add JARs... - navigate to find your log4j .jar you just # unpacked in the Java Folder - OK # 4) right click on your project in the Package Explorer - New - Folder - # in "Folder name" write "log4j" - click Advanced - select "Link to a folder in the # file system" - create a new folder "log4j" in your project folder in the file system # 5) Place this file you are reading right now in in the folder you just created. Name # the file as log4j.properties # 6) In Eclipse: Run - Run... - In the navigation bar on the left select either the # server, or the runnable class, or the JUnit test you want to log with log4j - # select the Classpath tab - User Entries - Advanced... - Add folders - OK - select # the "log4j" folder you created in your project - OK # 7) Repeat step 6 for other servers, runnable classes or JUnit tests you want to log # 8) Change in the following line the "org.example.foo.bar" with whatever you want. log4j.category.org.log=DEBUG # 9) Add the following import to the Java Class you want to log: # import org.apache.log4j.Logger; # 10) Add this lines to the Java Class you want to log: # /** # * Log4j logger # */ # static Logger log4j = Logger.getLogger("org.example.foo.bar"); # 11) Substitute in the code above "org.example.foo.bar" with whatever your wrote in # in the step 8. # 12) Add something like the following code in your Class whenever you want to log: # log4j.debug("WTF?"); # 13) Repeat steps 9, 10, 11 and 12 for every Java Class you want to log # 14) Enjoy! log4j.rootCategory=DEBUG, R, O # Stdout log4j.appender.O=org.apache.log4j.ConsoleAppender # File log4j.appender.R=org.apache.log4j.RollingFileAppender log4j.appender.R.File=log4j.log # Control the maximum log file size log4j.appender.R.MaxFileSize=100KB # Archive log files (one backup file here) log4j.appender.R.MaxBackupIndex=1 log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.O.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=[%d{ISO8601}]%5p%6.6r[%t]%x - %C.%M(%F:%L) - %m%n log4j.appender.O.layout.ConversionPattern=[%d{ISO8601}]%5p%6.6r[%t]%x - %C.%M(%F:%L) - %m%n


but the problem now that i want to use glassfish
I use eclipse with glassfish and no problems ,i see the logs in glassfish server log file
but when i use log4j i can not see the logs in eclipse console or in server log file

Please help
Thanks

Hi John ,

Thanks for your reply
I am sorry for being late.

First i forgot to mention that i am using eclipse IDE.
i was using org.hibernate.cfg.Configuration in my code which caused this problem.

But i have another problem now.

i started getting error : hibernate.cfg.xml not found

hibernate.cfg.xml is in scr folder and my mapping files are in src\comm folder just beside the persistence classes.

i tried this to work around :
java.io.File hibernateConfigurationFile= new File("C:\\Documents and Settings\\Raghda Ismail\\glassfish_workspace\\TestWebApp\\src\\hibernate.cfg.xml"); net.sf.hibernate.SessionFactory sf=new Configuration().configure(hibernateConfigurationFile).buildSessionFactory();


but i am getting this error

any idea what is wrong??

Thanks in advance

Hi every body ,

I am still having this problem.
could any body just have a look on the mapping and tell me if there is something wrong with it?

Thanks

hi David ,

Thanks for your reply.
You did not misunderstand ,what you said is exactly what i mean:
" I translate that to mean that a department can have only one head, not that a user can't have multiple departments"

and my problem with using one to one mapping is that i am not able to fetch users eagerly with the departments
I tried using this mapping :

<one-to-one
name="head"
class="helper.User"
foreign-key="department_head" //this is the name of the foreign key column in departments table
fetch="join"
/>

is there any thing wrong with this mapping??

Thanks in advance

Hi All,

I have User and Department classes ,the relation from Department to User is one to one unidirectional(Department has head ,and User can be head of only
one Department).
I did some search and found that to do this mapping i must do the following

<many-to-one
name="head"
class="helper.User"
column="department_head"
unique="true"
/>

and that unique="true" will force the relation to be one to one.

is that true??

I tried that but it works as many Departments to the same user, i add new department to user who is already a head and it works fine.

if this mapping is wrong ,could any one please tell me how to do it?

Thanks

Thanks dharmendra for your help

Hi every body,

I was reading code conventions from java.sun and i read these two lines and i really cannot understand them

Numerical constants (literals) should not be coded directly, except for -1, 0, and 1, which can
appear in a for loop as counter values.

i need to follow java standards in my current application and its important to me to understand it.

any help is appreciated.

Thanks in advance

Raghda

thanks Henry

hi everybody ,
please i need to know what does it mean that hash table is synchronized and hash maps are not?

Thanks

Thanks Balu ,
i moved log4j.properties in classes folder and it works fine now

Thanks David and Balu ,your answer solved my problem but now i am getting this warning

log4j:WARN No appenders could be found for logger (org.log).
log4j:WARN Please initialize the log4j system properly.

and i cannot see my logs
i have log4j.properties in log4j folder inside my application folder(beside src folder)

Thanks David,
But i am new to log4j and i don not know what do you mean by deploying log4j to the server
I am using tomcat, if you could give me more directions that would be great.

Thanks in advance

Hi everybody,

i am not sure if this is the right place to ask a question about log4j ,please redirect me to thr right place if i am wrong.
i followed this link to integrate log4j with eclipse

http://snippets.dzone.com/posts/show/3248

but when i run the servlet that use the Logger ,i get this exception
