deobfuscation does not work

[confile]

I tried to get remote log messages. I tried this:

Log.fatal("This is what an exception might look like", new RuntimeException("2 + 2 = 5"));

I can see that in WEB-INF/deploy/web/symbolMaps/ there are many files of size 4.3MB each. So I guess the symbolMaps are generated successful. 

My remote servlet config is:

<servlet>

  <servlet-name>gwt-log-remote-logger-servlet</servlet-name>

  <servlet-class>com.allen_sauer.gwt.log.server.RemoteLoggerServiceImpl</servlet-class>

<init-param>

<param-name>symbolMaps</param-name>

<param-value>WEB-INF/deploy/web/symbolMaps/</param-value>

      </init-param>

</servlet>

<servlet-mapping>

<servlet-name>gwt-log-remote-logger-servlet</servlet-name>

<url-pattern>/gwt/web/gwt-log</url-pattern>

</servlet-mapping>

On the client side I get

(-:-) 2014-02-20 15:22:04,388 [FATAL] This is what an exception might look like java.lang.RuntimeException: 2 + 2 = 5 at Unknown.X7b(Unknown Source:180) at Unknown.CTb(Unknown Source:518) at Unknown.ATb(Unknown Source:56) at Unknown.CVb(Unknown Source:29) at Unknown.GVb(Unknown Source:29) at Unknown.vQ(Unknown Source:53) at Unknown.N7b(Unknown Source:180) at Unknown.E7b(Unknown Source:345) at Unknown.R7b(Unknown Source:78) at Unknown.L7b(Unknown Source:138) at Unknown._6b(Unknown Source:290) at Unknown.d7b(Unknown Source:347) at Unknown.anonymous(Unknown Source:93) at Unknown.anonymous(Unknown Source:42)

On the server side I get:

What do I have to do to get the deobfuscation working?

I made a demo gwt project to show this problem: https://github.com/confile/gwtlogtest  

When I compile with style obfuscated I get on the client: 

(-:-) 2014-02-20 23:09:54,529 [FATAL] This is what an exception might look like java.lang.RuntimeException: 2 + 2 = 5 at Unknown.ui(StackTraceCreator.java:180) at Unknown.Zf(StackTraceCreator.java:518) at Unknown.Yf(Throwable.java:56) at Unknown.kh(Exception.java:29) at Unknown.mh(RuntimeException.java:29) at Unknown.PW(Testgwt.java:66) at Unknown.TW(Testgwt.java:52) at Unknown.ki(SchedulerImpl.java:180) at Unknown.bi(SchedulerImpl.java:345) at Unknown.oi(SchedulerImpl.java:78) at Unknown.ii(SchedulerImpl.java:138) at Unknown.Kh(Impl.java:290) at Unknown.Oh(Impl.java:347) at Unknown.anonymous(Impl.java:93) at Unknown.anonymous(UnloadSupport.java:42)

and on the server:

I use GWT 2.6

In my catalina.out I see: 

WARNING: Servlet configuration parameter 'symbolMaps' specifies directory 'WEB-INF/deploy/testgwt/symbolMaps/' which does not exist or is not relative to your server's current working directory '/'

Feb 21, 2014 12:08:11 AM com.allen_sauer.gwt.log.server.ServerLogImplJDK14 log

WARNING: In order to enable stack trace deobfuscation, please specify the 'symbolMaps' <init-param> for the com.allen_sauer.gwt.log.server.RemoteLoggerServlet servlet in your web.xml

How do I fix that?

[Fred Sauer]

Note this part of the error message:

         .....or is not relative to your server's current working directory '/'

You specified 'WEB-INF/deploy/testgwt/symbolMaps/', and the working directory is '/', which means it will expect '/WEB-INF/deploy/testgwt/symbolMaps/' to contain the symbol maps. Unless your webapp is deployed to '/', then this is wrong.

Please see https://code.google.com/p/gwt-log/wiki/GettingStarted

I made it working see my other post.

Now I find that remote logging only works with error and fatal messages. When I set

<inherits name="com.allen_sauer.gwt.log.gwt-log-TRACE" /> 

I do not get any trace, debug, info, warn messages reported to the server. They appear in the console but only error and fatal written to server logs.

Is there any option I miss?

[Fred Sauer]

Yes you need to configure the server-side logging level separately

How do I configure the server side log level? Could you please give an example?

Depends on what server side logging library you use, e.g. java.util.logging, log4j, etc.

Simply write Log.debug(...) ... Log.error(...) in your server side code (e.g. in a servlet) and make sure you see those messages.
