Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What version are you using? (morphia-0.99-SNAPSHOT/Driver: mongo-2.3/MongoDB 
1.6.5)

Hi currently I'm integrating morphia with play! framework. Now I have problem 
with Blob data type issue.

So I have this code:

String email = "my.email@gmail.com";
User user = (User) User.find("byEmail", email).get();

When I run it there are error as a stack trace below:

RuntimeException occured : java.lang.RuntimeException: 
java.lang.RuntimeException: java.lang.RuntimeException: 
java.lang.RuntimeException: java.lang.RuntimeException: 
java.lang.RuntimeException: com.google.code.morphia.mapping.MappingException:

And this is the exception detail in my console:

Notes:
In my class model User above, I have class model Profile which is have 
profilePic field using Blob type. When I try to change it to string, the 
exception is just gone, but my file is not uploaded (of course).

How can I fix this?

Thanks
