If the value is a valueBinding only the String #{xxxs.d} is serialized.
Please try it with a managed bean that contains only the file nothing else.

Hello Bernd,
there was of cource a value binding. I stripped the example to the
bones, to see if it works eventually.
I learned meanwhile why there's the serialization. It's for the state
saving between request. But the question remains, how can state saving
ever work, when there's a class, which is not serializable
(DeferredFileOutputStream)?

Hello Helmut,
oh tc:file without a valueBinding.
Please add a valueBinding to tc:file.
I should declare the property value required and it should be a valueBinding
Please consult the JSF Spec why stateSaving is required.

Hello Bernd,
there isn't any field in the bean. The exceptions occurs even there's
any bean at all. Example:
<f:view>
<tc:page label="Test" width="200px" height="100px">
<tc:file/>
<tc:button label="Submit"/>
</tc:page>
</f:view>
The problem is, that JSF tries to serialize the view. This can't work,
because the fileItem isn't serializable. The question is, why should
the view be serialized? Is this a problem with Tomcat (5.5.15)? I
use the standard configuaration.

Hello Helmut,
I didn't know your managed bean. Can you declare the field in the
managed bean transient. Maybe the managed bean is a tabChangedListener?

What do you mean exactly with statesaving tags? Any JSF or Tabago with a
state
attribute?
Helmut
No, the question was for removing these tags

Adding Serializable doesn't help.
I don't know any savestate or keepalive tags.
Helmut
AnlagenController implements the Serializable Class??
Is there any savestate or keepalive tag in your jsp?

Hi,
I want to do a file uplaod with Tobago, but I always get an

classpath:

I've no idea what's wrong or missing. And there's no
documentation,
except the simple example in the source...
