[jira] Created: (TAPESTRY-650) ClassNotFoundException thrown when deserializing an object from a client persistent property
ClassNotFoundException thrown when deserializing an object from a client persistent property
--------------------------------------------------------------------------------------------
Key: TAPESTRY-650
URL: http://issues.apache.org/jira/browse/TAPESTRY-650
Project: Tapestry
Type: Bug
Components: Framework
Versions: 4.0
Environment: Windows XP
Reporter: Kent Tong
An object of a class defined in a web-app can be serialized to be stored as a client persistent property, but when it is deserialized, a ClassNotFoundException is thrown. It works fine if a session persistent property is used instead. The Tapestry and Hivemind jar files are put into c:\tomcat\shared\lib. A test case is shown below.
P1.html is:
<html>
value is: <span jwcid="@Insert" value="ognl:foo.n"/>
<form jwcid="form">
<input type="submit" value="OK"/>
</form>
</html>
P1.page is:
<?xml version="1.0"?>
<!DOCTYPE page-specification PUBLIC
"-//Apache Software Foundation//Tapestry Specification 4.0//EN"
"http://jakarta.apache.org/tapestry/dtd/Tapestry_4_0.dtd">
<page-specification>
<component id="form" type="Form">
<binding name="listener" value="listener:onSubmit"/>
</component>
</page-specification>
P1.java is:
public abstract class P1 extends BasePage implements PageBeginRenderListener {
@Persist("client")
public abstract Foo getFoo();
public abstract void setFoo(Foo foo);
public void pageBeginRender(PageEvent event) {
if (getFoo() == null) {
setFoo(new Foo());
}
}
public void onSubmit() {
getFoo().n++;
}
}
Foo.java is:
public class Foo implements Serializable {
private static final long serialVersionUID = 8812267940530652652L;
public int n = 0;
public int getN() {
return n;
}
}
The stack trace is:

[jira] Commented: (TAPESTRY-650) ClassNotFoundException thrown when deserializing an object from a client persistent property
Posted by "Andreas Andreou (JIRA)" <ta...@jakarta.apache.org>.
[ http://issues.apache.org/jira/browse/TAPESTRY-650?page=comments#action_12329995 ]
Andreas Andreou commented on TAPESTRY-650:
------------------------------------------
I tried your code with 4.0-beta-7 (but without annotation support, I defined the persistence strategy in the jwc file) ,
and I have 2 remarks.
1) I did NOT get any exceptions thrown (so, I don't know why you get them - does it have to do with annotations???),
2) the persistent value does NOT update past 1. Only when i use persist="session" all work ok.
Then I remembered that for the page recorder to record changes of a property, you have to use the correct setter,
i.e. in onSubmit() add a line such as setFoo(getFoo())
This was also mentioned in TIA as the correct way, especially when working in a cluster.
In a single dev machine, the simple getFoo().n++ works (when persist="session") because there's
only an instance of the Foo property, and the n++ 'touches' it.
In a cluster, or when persist="client" you have to trigger the page recorder (using setFoo(...))

> An object of a class defined in a web-app can be serialized to be stored as a client persistent property, but when it is deserialized, a ClassNotFoundException is thrown. It works fine if a session persistent property is used instead. The Tapestry and Hivemind jar files are put into c:\tomcat\shared\lib. A test case is shown below.

[jira] Commented: (TAPESTRY-650) ClassNotFoundException thrown when deserializing an object from a client persistent property
Posted by "Kent Tong (JIRA)" <ta...@jakarta.apache.org>.
[ http://issues.apache.org/jira/browse/TAPESTRY-650?page=comments#action_12330336 ]
Kent Tong commented on TAPESTRY-650:
------------------------------------
I'm testing it with beta 7, it will throw a ClassNotFoundException, no matter I'm using annotation or <property> to declare the property.
Yes, you're right that I should call setFoo() again to trigger the page recorder. But this has nothing to do with the bug here because the exception makes it impossible for the counter to get to 2 (unless "session" is used).
