Hi,

I am getting this error while executing a custom written java service.
The service performs the work of saving the document to Local directory. Which the filename is given to it as a variable, it ends up in the error :

java.lang.ClassCastException: com.wm.data.ISMemDataImpl

stack - trace :

any help or earlier experience on similar issue?

memory issue …Cache the service or flush old memory usage with server restart

Hi,

Its a common java error.

you can get more details at casting - Explanation of ClassCastException in Java - Stack Overflow

or post the java code here. I will try to solve it.

Thanks for reviving this old topic… But, it was in 2011, and I might have got the answer next day through some work on it.

This was probably not even asked in TechCommunity and was WMuser question

Even then, thanks a lot for taking time to respond over.
