Hi,

Cache_Lite has integrated serialize function, and I guess it's
basically a wrapper of the php serialize function. I can cache and
retrieve the object without problem. The issue is if I leave some java
objects in the cache without using for a while, they become invalid or
expired or sth, as you could see from the error message.

I'll take a look at JPersistenceAdapter.php tmw, but please let me
know if I was wrong, thanks.

Regards,

Rong

Hi,

You cannot cache java objects this way. Please serialize it. 

Please see the JPersistenceAdapter.php and the serialize php test from the php5 test folder for an
example.

Hi,

I'm wondering whether the connection between PHP scripts/Apache and
the Java bridge has a timeout? I'm using the standalone mode and I
cached (using PEAR Cache_Lite) the Java object created with the "new
Java(...)" call, so the object can be used to serve more than one
request. It worked well initially, until after some time (probably
some idle time), the cached object seemed no longer valid, and yielded
the following error:

Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: Invoke
failed: [[o:JavaBridge]]->deserialize((o:String)[o:String],
(o:int)[o:Integer]). Cause: java.lang.IllegalArgumentException:

Any idea about how to make this timeout unlimited? or is this (caching
java object) a good way to maintain persistent object across the
bridge? thanks.
