Java backed webscript in Share

Question asked by dmartinc on Mar 23, 2011

I have a java backed webscript deployed in Alfresco and it works ok (it is successfully used by Share dashlets). I would now like to deploy it in Alfresco Share.

The reason to do that is that I need to call some java code to make CAS SSO with third application from Share, so REST (javascript) + Alfresco java webscript combination is no more usable (I need to have session information from Share in webscript).

As far as I have found out until now, the problem is that the webscript configuration file is in the wrong location, so I would appreciate help with it or the working example with file locations so I could make it work on my system.

The system is:
JBOSS 4.3 + Alfresco 3.4 + Alfresco Share 3.4.0b

The web beans configuration file custom-slingshot-application-context.xml is placed in JBOSS_ROOT\server\default\conf\alfresco\web-extension contains:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>
   <bean id="webscript.org.alfresco.test.intaliobridge.get" parent="webscript" class="org.alfresco.module.test.IntalioBridge" />
</beans>

The webscript description file intaliobridge.get.desc.xml is placed in JBOSS_ROOT\server\default\deploy\deploy.last\share.war\WEB-INF\classes\webscripts\org\springframework\extensions\webscripts  and it contains:
<webscript>
  <shortname>Intalio bridge</shortname>
  <description>Return intalio data</description>
  <url>/intaliobridge</url>
  <format default="json">any</format>
</webscript>

Jar file "intaliobridge.jar" is placed in folder JBOSS_ROOT\server\default\deploy\deploy.last\share.war\WEB-INF\lib and the package and class name of the webscript are:

package org.alfresco.module.test;
public class IntalioBridge extends AbstractWebScript {
}

When I access the web script it says "File not found" in browser but the script is successfully registered and displayed in the webscripts list https://localhost:8443/share/page/index/all.

The error (JBOS output) is:

16:10:34,044 ERROR [AbstractRuntime] Exception from executeScript - redirecting to status template error: 02230010 Cannot locate template processor for template

The most similar problem on internet, that I have found, is in this link http://forum.springsource.org/showthread.php?t=93411. According to that, problem is that webscript description file is on the wrong path and SURF doesn't know how to find the java class to display the output.

I have tried to place the webscript description file in various places (folders under WEB-INF) but none of it worked.
