Hi all,
I am trying to write a tag handler for a custom tag
(xdoclet-1.3-SNAPSHOT-cvs). The tag's example is:
@ejb.auth
parameter-object=”code”
type="both"
In the tag handler:
/**
* @xdoclet.taghandler namespace="EjbAuth"
*/
public class AuthTagsHandler extends XDocletTagSupport {
/**
* Detects if the method is using before processing
* @doc.tag type="block"
*/
public void ifBeforeAuthRequired(String template) throws XDocletException {
XMethod method = getCurrentMethod();
XDoc doc = method.getDoc();
java.util.List tags = doc.getTags();
for (java.util.Iterator i = tags.iterator(); i.hasNext(); ) {
XTag thisTag = (XTag)i.next();
System.out.println("Tag name is: " + thisTag.getName());
java.util.Collection attrs = thisTag.getAttributeNames();
for (java.util.Iterator h = attrs.iterator(); h.hasNext();) {
Object thisAttName = h.next();
System.out.println("\tAtt Name is: " + thisAttName.toString());
}
}
String value =
getTagValue(
FOR_METHOD,
"ejb.auth",
"parameter-object",
null,
null,
true,
true
);
System.out.println("EJBAuth is: " + value);
value =
getTagValue(
FOR_METHOD,
"ejb.auth",
"action",
null,
null,
true,
true
);
System.out.println("EJBAuth is: " + value);
value =
getTagValue(
FOR_METHOD,
"ejb.auth",
"type",
null,
null,
true,
true
);
System.out.println("EJBAuth is: " + value);
if (value != null) {
if (value.equalsIgnoreCase("both") || value.equalsIgnoreCase("before")) {
generate(template);
}
}
}
}
The session-custom.xdt template is like:
<XDtMethod:forAllMethods>
<XDtEjbIntf:ifIsInterfaceMethod superclasses="false" interface="remote">
<XDtMethod:ifHasMethodTag tagName="ejb:auth">
...
<XDtEjbAuth:ifBeforeAuthRequired>
// doing before
</XDtEjbAuth:ifBeforeAuthRequired>
...
The method in question is tagged:
/**
* Finds a full value of the action set by it's code
* @param code
* @return
*
* @ejb.interface-method
* @ejb.transaction type="Required"
* @blah action=”code” parameter-object=”code” type=”code”
* @ejb.auth
* parameter-object=”code”
* type="both"
*/
The relevant output from running ant is:
[exec] [ejbdoclet] Tag name is: param
[exec] [ejbdoclet] Tag name is: return
[exec] [ejbdoclet] Tag name is: ejb.interface-method
[exec] [ejbdoclet] Tag name is: ejb.transaction
[exec] [ejbdoclet] Att Name is: type
[exec] [ejbdoclet] Tag name is: blah
[exec] [ejbdoclet] Tag name is: ejb.auth
[exec] [ejbdoclet] (XDocletMain.start 53 ) Running XDoclet failed.
[exec] [ejbdoclet] (XDocletMain.start 54 ) <<Mandatory parameter
'parameter-object' missing for ejb.auth tag in findFullByCode method of
com.dcs.applications.service.ActionSetServiceBean class.>>
[exec] [ejbdoclet]
/home/collinl/workspaces/UserAuthorities/ejb-applications/build.xml:233:
XDoclet failed.
[exec] [ejbdoclet] at xdoclet.DocletTask.start(DocletTask.java:471)
As you can see, I'm listing out the tags on the current method, but the
attributes for the blah and ejb.auth tag are not included. If I remove
the parameter-object="code" line under ejb.auth, then I do get the type attribute found.
Right now, I'm lost. Why does the positioning of the attributes matter
to the tag. Why doesn't the tag listing print out all the attributes...
I've been looking at this all day, with not a clue as to how to fix it.
The cvs snapshot that I'm using is dated April 26th 2005, and I'm now
looking at retrieving another snapshot and trying it out... but given
that other tags used on ejb beans are working correctly with multiple
attributes, somehow I think I'm missing something.
Cheers for any help,
