property的读取&log4j配置

1.log4j 如下:

 <appender name="sf.easyajax.remote.IpFilter" class="org.jboss.logging.appender.RollingFileAppender"> 
    <param name="File" value="/${jboss.server.home.dir}/log/IpFilter.log"/>                      
    <param name="Append" value="true"/>                                                        
    <param name="MaxFileSize" value="500KB"/>                                                  
    <param name="MaxBackupIndex" value="1"/>                                                   
                                                                                               
    <layout class="org.apache.log4j.PatternLayout">                                            
      <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>                              
    </layout>                                                                                  
  </appender> 


 <logger name="sf.easyajax">                                                                              
  <level value="ERROR" />                                                                 
   <appender-ref ref="sf.easyajax.remote.IpFilter"/>
 </logger> 

2.ejb context的初始化 & ejb 远程调用

try {
    Properties props = new Properties();
    Properties icProps = new Properties();
    InputStream in = getClass().getResourceAsStream(
      "jndi.properties"); 

    if (in != null) {
     try {
      props.load(in); 

      // icProps = new Properties(); 

      icProps.put(Context.INITIAL_CONTEXT_FACTORY, props
        .getProperty("java.naming.factory.initial"));
      icProps.put(Context.PROVIDER_URL, props
        .getProperty("java.naming.provider.url"));
      icProps.put(Context.URL_PKG_PREFIXES, props
        .getProperty("java.naming.factory.url.pkgs")); 


     } catch (IOException e) {
      e.printStackTrace();
     }
    }
    context = new InitialContext(icProps); 

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=10.2.1.234:1099
