[pulkit tiwari，修改在6 年前。]

Hi everyone,
I am currently developing a liferay 7 plugin portlet and after configuring all the settings of service builder in the plugin project including service.xml, ext-sping.xml, service-ext.properties . I am getting this Unknow entity exception whenenver i try to use XXXLocalServiceUtil class to save or update or perform any other operation on database.

Below are the exception logs i am getting :-

I am attaching service.xml, ext-spring.xml ,portal-hbm.xml and web.xml files.
Please guide me how to resolve this exception. Am i missing something to configure or i configured wrong database settings.

Likely cause? You've included the service jar in your module, instantiated an instance of Pe_userImpl yourself in your own class loader and are trying to push that through the service layer to update.

I am getting instance of Pe_userImpl from Pe_userLocalServiceUtil.create() method and neither i am forcing it through service layer as i am using LocalServiceUtil add() method to save it.
My Project is plugin Spring mvc portlet not a module thats why service jar is included in it.
I am trying to insert a value in the table , something like below code,

long id=CounterLocalServiceUtil.increment(Pe_mail_utility.class.toString());

Pe_mail_utility pe_mail_utility =Pe_mail_utilityLocalServiceUtil.createPe_mail_utility(id);
pe_mail_utility.setUser_id(userId);
pe_mail_utility.setStatus(PEConstants.MAIL_STATUS_INITIALISED);
pe_mail_utility.setRetry_count(0);
pe_mail_utility.setMail_s3_id(UUID.randomUUID().toString()+PEConstants.UNDERSCORE+pe_mail_utility.getId());
Pe_mail_utilityLocalServiceUtil.addPe_mail_utility(pe_mail_utility);

And i am getting exception unknown entity Pe_mail_utilitymodelImpl .
There is this file named as portlet-hbm.xml in which all entity mappings are defined. Now this file is getting read, but i think it is getting associated to default liferay session factory ,instead of session factory i defined in ext-spring.xml . I dont want to manually include this file as mapping resource in my session factory as that will not be the right way of doing things. This settings used to work fine on liferay 6.2 server.
Is there something changed regarding session factory in liferay 7 ?
Also i am developing a liferay 7 portlet plugin not a module.

The attached code snippet does not correspond to the stack trace.

check if your issue is related to class loading.

Possible related issue and solution:
Unknown entity for Custom Filder

[Lemuel Lumapas，修改在6 年前。]

Were you able to solve this issue? I encountered the same error.

[pulkit tiwari，修改在6 年前。]

No , i wasn't.
I had to build a new module for connecting to external database and then copied this module's jar file to tomcat ext folder and also deployed this to server. And then was able to connect to external database through LocalServiceUtil methods.
