[jboss-user] [JBoss Seam] - Re: Help injecting the SessionContext
Stop, forget what I said. I just had a look at UnsafeObjectFieldAccessorImpl.java and its
set-method:
public void set(Object obj, Object value)
| throws IllegalArgumentException, IllegalAccessException
| {
| ensureObj(obj);
| if (isFinal) {
| throw new IllegalAccessException("Field is final");
| }
| if (value != null) {
| if (!field.getType().isAssignableFrom(value.getClass())) {
| throw new IllegalArgumentException();
| }
| }
| unsafe.putObject(obj, fieldOffset, value);
| }
As you can see, the IllegalArgumentException (that is the root cause auf your exception)
is thrown, if the class of a field (namely sessionContext here) doesn't fit the class
of the object that should be injected.
Or, to put in a nutshell:
Whatever Seam tries to inject into private SessionContext sessionContext; is not
compatible to class SessionContext! Try it like this:
@In(required=false)
| private Object sessionContext;
|
| ...
|
| log.info("The class of the injected thing is: " +
sessionContext.getClass());
Then you will see what's injected and you can start solving the issue.
