HELP!!!! alfresco actions

enkidu

hi mates,

need help.. i want to transform xml to pdf using a custom transformer (a script batch file). i copy and paste the example from http://docs.alfresco.com/4.1/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Ftasks%2Fserv-runtimetransformer-extend.html

but i didnt know how the action will be performed (didnt show up under actions). did i need to do something more then create a file under extensions? some advice would be nice.

using alfresco 4.2.d

See if <a href="http://ecmarchitect.com/images/articles/alfresco-actions/actions-article-2ed.pdf">this tutorial</a> on custom actions is of any help, particularly the part about adding the custom action to the Share user interface through the custom config.

hi jeff,

thnx for ur reply.. i downloaded the alfresco sdk but i dont know which one of all those jar files are necessary to compile the code in ur example.. some hints would be nice.
i downloaded the sdk from https://process.alfresco.com/ccdl/?file=release/community/build-4848/alfresco-community-sdk-4.2.e.zip

some issues trying to compile the sample code with some classes like i.e. NodeRef.

still waiting for an answer!.. its easier to get response from jesus as from a developer of the alfresco staff

jpotts

If you import the SDK into your Eclipse workspace and then make the SDK AlfrescoEmbedded project a dependency for the project you are working on, you won't have to hunt down JAR files. Everything will compile.

If you would prefer to use Maven, that's another option. In that case you don't need to download the SDK at all.

All of this is actually covered in various tutorials, books, and wiki pages, so that's probably why you haven't gotten an answer.

Hi jeff,

i got the example work thanx to your hint.. but now i wanna go a step further and get the name of the node so i tried this: http://wiki.alfresco.com/wiki/NodeRef_cookbook

i copy and paste:

       ServiceRegistry serviceRegistry = (ServiceRegistry) beanFactory.getBean(ServiceRegistry.SERVICE_REGISTRY);
       NodeService nodeService = serviceRegistry.getNodeService();
       ContentService contentService = serviceRegistry.getContentService();
       FileFolderService fileFolderService = serviceRegistry.getFileFolderService();

but now i have the problem that he didnt find beanFactory.. where did i get it from? any ideas?

– ok i found the solution:

    <bean id="logger-action" class="org.alfresco.sample.LoggerActionExecuter" parent="action-executer">
      <property name="nodeService">
         <ref bean="nodeService" />
      </property>
   </bean>

hi jeff,

can u give me a hint how to programm a custom transformer lets say: i want to transform a xml from a folder "source" using a stylesheet xsl and store the result in folder "target".

i would like use RuntimeExecutableContentTransformerWorker but didnt find any tutorial which explains how to do so. the only one i found is: http://wiki.alfresco.com/wiki/Content_Transformations

but the java code is useless if u wanna do ur own transformer

here is a comment i found at amazon: http://www.amazon.de/Alfresco-Developer-Guide-Jeff-Potts/dp/1847193110

– amazon –
Alfresco has some of the worst documentation that I have ever seen. This book is only slightly better. No matter what I try and do I have to go to the community to get the real, workable information. I just seem to hit what should be the simple stuff that is not documented anywhere.
– amazon –

maybe the alfresco staff should take it more serious

i totally agree.. alfresco has a problem with its documentation and code samples are poor

jpotts

enkidu,

Your comment isn't really constructive. If you point to something in http://docs.alfresco.com, which is the official documentation, that you think could be improved that would be helpful.

You are in the forums, which is a community-managed resource, asking for help. You'll notice that people who get help are those who (1) read the documentation, (2) try various things, including reading the source code, (3) provide a lot of details about what they are having trouble with, and (4) remain patient and respectful of those who give their time outside of work to help others.

It's okay to be frustrated, but saying only that we have a problem with our documentation and that the code samples are poor does nothing to improve the situation and it makes people reluctant to help you.

Make sure you use NodeService instead of nodeService. The lower-cased bean is private to Alfresco and is missing things like security, audit, and transactions. The upper-cased bean is public. That's the one you should be injecting.

hi jeff,

i just wanna make a point.. and that is there is no decent tutorial about custom actions. and thats a fact. prove me wrong and post the link where i can find a documentation including sample code and i agree that i was completly wrong. but as long as u cant proof me wrong i will stick to my point.

and if u take a closer look at the forum u will realize that there is a problem.

hi jeff,

got my custom action running and shown in UI. just for the beginning i just inherit from ActionExecuterAbstractBase nothing special and make a jar this i copied to "$alfrescodir\tomcat\webapps\alfresco\WEB-INF\lib" and the XML file i copied to -> goes to ($alfrescodir\tomcat\shared\classes\alfresco\extension).

can u tell me why i get WHAAAT? instead of WOOOOO?

package com.myfirstaction;

   private Log logger = LogFactory.getLog("com.myfirstaction");
   protected NodeService nodeService;
   public final static String NAME = "myaction-action";
   
   @Override
   protected void executeImpl(Action arg0, NodeRef arg1) {
      // TODO Auto-generated method stub
                  logger.error("WHAAAAT????");
      logger.info("WOOOOOO!!!!!");

kaynezhang

alfresco use log4j to record log messages. by default The root category is set to error(which is configured in alfresco\WEB-INF\classes) .
As your categories have not had their log level set ,It will inherit their log level from the root, which is set to ERROR.
So only if the level is ERROR or higher will be dumped to log file,that's why you get WHAAAT instead of WOOOOO.

hi kaynezhang.. if u compare the both code i posted u will see there is not so much difference, but at the last code i posted the code will output INFO as well not just ERROR so im wondering what im missing? where does my bottom code know that he now should output INFO as well?

enkidu

thnk u all for ur help and ur patience
