Anyone using soafaces for client server communication ?

http://code.google.com/p/soafaces/

I've tried to get it working but it seems to be broken ... it claims
to allow passing of Object[] but when I try to use it (Object[] objs =
new Object[2]) I get a Serialization exception which seems to be from
generated code ...

com.google.gwt.user.client.rpc.SerializationException:
[Ljava.lang.Object;
at
org.soafaces.services.client.rpc.UniversalClientRPC_TypeSerializer.raiseSerializationException
(transient
source for
soafaces.services.client.rpc.UniversalClientRPC_TypeSerializer:3133)
at
soafaces.services.client.rpc.UniversalClientRPC_TypeSerializer.serialize
(Native Method)

It does work if I pass a single argument, anyone have any experience
using this ?

[mike_mac]

On further investigation this seems to be a hosted mode issue and
different behaviour of instanceof between hosted mode and complied
versions of the code.

Passing an Object[] called obj that has two objects that implement
IsSerializable
results in "obj instanceof Serializable" returning true in hosted mode
but false in the compiled Javascript.

See
org.soafaces.services.client.rpcGenericDataUtil.createGenericDataWrapper
(Object obj) in soafaces source.

Anyone have a logical explanation why hosted mode thinks its a
Serializable object ? Object is not Serializable right so neither
should Object[] right ?

Hi Mike,

I think I see the problem. In Hosted mode, java is evaluating the
Object[] as instanceof Serializable since per java spec every java
array implements Serializable interface. Production mode must be
letting this slip by. So actually looks like an inconsistency between
compiled javascript mode and java spec.

I will verify, but the fix should be easy in soafaces to move the the
check for instanceof Object[] earlier in the if else chain. I will
work on a bug fix for soafaces.

Thanks,
Sam

Hi Sam and Mike,

I'm currently reviewing Soafaces but:
- I can't get it 100% to work;
- I couldnt find a soafaces related forum.

It could be my problem is related to the problem just described.
Because the object (string) returned by service doesn't seem to be
received by the client.

I created a normal gwt (1.5.2) client and added:
- jettizon
- soafaces-services-client
- soafaces-services-servlet-nomule
- xstream
- added lines to ...gwt.xml:
<source path="client"/>
<inherits name='org.soafaces.services.Services'/>

When running my app and invoking the service
'onUniversalClientSuccess' is triggered. So far so good, but the
string sended by server "You got it" isn't received.
The result object parameter of onUniversalClientSuccess is null, see
my code and log output below.


Any ideas / tips / additional examples ?


I get number of errors/warnings in my log:

[Sam Taha]

Do you only see this problem in hosted mode? Do you see it in web
mode?

What version of soafaces are you using?

Are you getting any servlet errors?

Hi Sam,

Thank you for responding, I really like to get soafaces up and
running.

The jars I'm using are:
jettison-1.0.1.jar
soafaces-services-client-2.4.2.jar
soafaces-services-servlet-nomule-2.4.2.jar
xstream-1.2.2.jar

In my hosted browser at least:
- onUniversalClientSuccess is triggered

But when building a jar and depoying in tomcat:
- onFailure is triggered
I couldn't find any error message, the exception thrown in onFailure
doesn't have a message in it.

Any ideas ?
Or is there any change you could post an (maven2 enabled) example
using gwt and soafaces ?

correction:
'But when building a JAR and depoying in tomcat: '

I'm not building a JAR, but I'm building a war...
