Flavien Binet commented on WW-2796:
-----------------------------------
some update, i managed to get it working with velocity-tools-1.4 :
I subclassed the VelocityManager class, overriden the createContextMethod, and
replaced the deprecated constructor by the new one :
MyVelocityManager.java :
--------------------------------------------------------------------------------------
import java.util.Iterator;
import java.util.Map;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.util.VelocityStrutsUtil;
import org.apache.struts2.views.jsp.ui.OgnlTool;
import org.apache.struts2.views.util.ContextUtil;
import org.apache.struts2.views.velocity.StrutsVelocityContext;
import org.apache.struts2.views.velocity.VelocityManager;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.context.Context;
import org.apache.velocity.tools.view.context.ChainedContext;
import com.opensymphony.xwork2.util.ValueStack;
public class MyVelocityManager extends VelocityManager
{
private static final Logger LOG =
Logger.getLogger(MyVelocityManager.class);
public Context createContext(ValueStack stack, HttpServletRequest
req, HttpServletResponse res) {
VelocityContext[] chainedContexts = prepareChainedContexts(req,
res, stack.getContext());
StrutsVelocityContext context = new
StrutsVelocityContext(chainedContexts, stack);
Map standardMap = ContextUtil.getStandardContext(stack, req,
res);
for (Iterator iterator = standardMap.entrySet().iterator();
iterator.hasNext();) {
Map.Entry entry = (Map.Entry) iterator.next();
context.put((String) entry.getKey(), entry.getValue());
}
context.put(STRUTS, new VelocityStrutsUtil(getVelocityEngine(),
context, stack, req, res));
ServletContext ctx = null;
try {
ctx = ServletActionContext.getServletContext();
} catch (NullPointerException npe) {
// in case this was used outside the lifecycle of struts
servlet
LOG.debug("internal toolbox context ignored");
}
if (toolboxManager != null && ctx != null) {
// here is the new constructor :
ChainedContext chained = new
ChainedContext(getVelocityEngine(), req, res, ctx);
chained.setToolbox(toolboxManager.getToolbox(chained));
return chained;
} else {
return context;
}
}
}
--------------------------------------------------------------------------------------
Now just add this line :
struts.xml :
--------------------------------------------------------------------------------------
<constant name="struts.velocity.manager.classname"
value="your.package.MyVelocityManager" />
--------------------------------------------------------------------------------------
and struts will use your new manager instead of the build in one.
Tested with velocity-tools-1.4 only, it seems to work fine.
Hope this help ;-)
