ClassNotFoundException: DLFileEntryImpl

[Arthur Grohe, geändert vor 11 Jahren.]

Hi guys,

On my 6.1.0 Portal Instance with a 6.1.0 SDK-Portlet that makes use of ServiceBuilder and the DL-Api
this line:
DynamicQuery query = DynamicQueryFactoryUtil.forClass(DLFileEntry.class)

produces this error:

16:46:46,319 ERROR [DynamicQueryFactoryImpl:83] Unable find model

I searched for hours for the reason but I didnt find it.
I also tried to add portal-impl.jar to my lib/ folder, but that didnt help and is not nice ;)

Thanks for any help!

Hi,

I hope this link may help you !! Click Here

Arthur Grohe:

DynamicQuery query = DynamicQueryFactoryUtil.forClass(DLFileEntry.class)

This is your problem. You're using the wrong class loader. Instead of your line, you'd use:

 DynamicQuery query = DynamicQueryFactoryUtil.forClass(DLFileEntry.class, PortalClassLoaderUtil.getClassLoader());

[Arthur Grohe, geändert vor 11 Jahren.]

Wow, that worked, thank you!

[Arthur Grohe, geändert vor 11 Jahren.]

Hi,
can you tell me why this DynamicQueryFactoryUtil.forClass(DLFileEntry.class, PortalClassLoaderUtil.getClassLoader());
is the right call? How should I have found this out by myself, is there a docu that suggests to use this on 6.1.0 or where did you get this information?

Thanks

[David H Nebinger, geändert vor 11 Jahren.]

The necessary class loader is selected by knowing which class loader is used to handle the Xxx model impl class (not the model interface). In this case you are using DLFileEntryImpl which is in the portal, therefore it's class loader is used when using DQ.

[Arthur Grohe, geändert vor 11 Jahren.]

Ok, thanks
