BPEL Adapters & Scheduling

Question

Hi guy,
I have downloaded BPEL Process Manager 2.1.2 (the last production version, i think) and already read documentation ... I have some questions:
1) Do exist an FTP Adapter to move file via FTP? I have seen File Adapter and that it moves/handles file on the same machine (I think so). Is it possible using File Adapter? If it's possible, how can I use File Adapter to do it?
2) Where can I find a complete list about Oracle BPEL Adapter (because I also need an E-mail Adapter to manage sending and receiving e-mail with attachment or DB Adapter to manage database connection)
3) Is it possible to schedule BPEL Process activation inside BPEL Process Manager?
Thanks for your answer.
Bye,
Seba.

No, but have implemented something that works.
Basically, using quartz as a servlet. This schedules the initation of a generic Java class which pulls out job config information from quartz job.xml file. This java class then calls another java class which connects to the bpel jndi server, and kicks of the bpel process.
Initially I had problems understanding what functionality the Quartz library provided with BPEL actually supported. It doesn't support reading job/trigger definitions from an xml file, so we decided to go with a later version, Quartz 1.6.0. This then led to conflicts between the two libraries if deploying your servlet to the OC4J_BPEL home. A fix for this was to create an orion-web.xml, and add:
<web-app-class-loader search-local-classes-first="true"/>which causes it to look at the version of the quartz lib deployed with the servlet before looking at the earlier quartz libs packaged inside orabpel.jar in the applib directory.
The next problem I had was related to the java class which kicks off the bpel processes. For this to be able to lookup bpel objects in the OC4J_BPEL instances JNDI server, I had to add:
parent="orabpel"to the config file ~/OraHome_2/j2ee/OC4J_BPEL/config/server.xml for the servlet web application otherwise i would get the error:
Caused by: java.lang.Exception: Failed to create "ejb/collaxa/system/DomainManagerBean" bean;
exception reported is: "javax.naming.NameNotFoundException: ejb/collaxa/system/DomainManagerBean not foundI think that's about everything, but if anything else springs to mind I'll edit the post.
If you use quartz as a servlet, you'll have to add the entry:
  <servlet>
    <servlet-name>QuartzInitializer</servlet-name>
    <servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
       <init-param>
          <param-name>config-file</param-name>
          <param-value>quartz.properties</param-value>
      </init-param>
      <init-param>
          <param-name>shutdown-on-unload</param-name>
          <param-value>true</param-value>
      </init-param>
      <init-param>
          <param-name>start-scheduler-on-load</param-name>
          <param-value>true</param-value>
      </init-param>
  </servlet>to you're web.xml, in addition to other servlets you create.
