Hi all

I'm facing issues with backend webscript when implementing the DeclarativeWebScript helper class.
The facts:
When using DeclarativeWebScript, the class is NOT executed.
   -> no log entry
   -> variables a not recognized by ftp template
When using AbstractWebScript, the class is executed.
   -> log entry OK

I'm using stricly the same xml description, class declaration and file locations.
details are below.
COuld please tell me what if I'm missing something ?

Another question: I can't have any debug log in catalina.out file (only logger.error) even
with these settings in log4j.properties
   log4j.logger.org.springframework.extensions.webscripts=debug
   log4j.logger.org.springframework.extensions.webscripts.ScriptLogger=debug
   log4j.logger.org.springframework.extensions.webscripts.ScriptDebugger=off

Thanks a lot for your help !

class using DeclarativeWebScript (not executed)


package org.alfresco.module.ks2.dlockws;

import …..
   
   public class lock extends org.springframework.extensions.webscripts.DeclarativeWebScript
   {
      private Logger logger = Logger.getLogger(lock.class);

      public Map<String, Object> executeImpl (WebScriptRequest req, WebScriptResponse res)
      throws IOException   {
          
         Map<String, Object> model = new HashMap<String, Object>();
         String txt = "";
         try
          {                       
            txt = "String from java";

              logger.debug("—– test log debug ——-");
              logger.info("—– test log info ——-");
              logger.warn("—– test log warn ——-");
              logger.error("—– test log error2——-");
              
          }
          catch(WebScriptException e)
          {
             throw e ;
          }
          
          model.put("servertext", txt);
         return model;
      
       }
   
      public Logger getLogger() {
         return logger;
      }

      public void setLogger(Logger logger) {
         this.logger = logger;
      } 
   }

class using AbstractWebScript (works fine)



package org.alfresco.module.ks2.dlockws;

import …

   public class lock extends org.springframework.extensions.webscripts.AbstractWebScript
   {
      
      private Logger logger = Logger.getLogger(lock.class);
      
      public void execute (WebScriptRequest req, WebScriptResponse res)
      throws IOException
         
       {
         try
          {
                       

              logger.debug("—– test log debug ——-");
              logger.info("—– test log info ——-");
              logger.warn("—– test log warn ——-");
              logger.error("—– test log error2——-");
              
          }
          catch(WebScriptException e)
          {
             throw e ;
          }
        
       }

      public Logger getLogger() {
         return logger;
      }

      public void setLogger(Logger logger) {
         this.logger = logger;
      } 
   }

I finally found my problem after days working around !!

It was a beginners mistake: (hope it can help other beginners)
I was not implementing correctly the DeclarativeWebScript interface (see below).
Because I was missing the @Override instruction, type error was not shown in Eclipse.

Correct implementation:


@Override
protected Map<String, Object> executeImpl(WebScriptRequest req, Status status)
 ‍‍‍‍

Incorrect implementation:


public Map<String, Object> executeImpl (WebScriptRequest req, WebScriptResponse res)
      throws IOException
