[pete_999_I]

ok I have unchecked – create abstract class and enable pagination for query results — and all got generated. I have not checked if all generated code is correct but at least I managed to narrow down what was causing the initial error

[Loyal Water]

Can you go through this FAQ and try the steps mentioned here:-
https://www.genuitec.com/forums/topic/db-error-generating-artifacts/

[Sean Parsons]

I also find this error – removing abstract creation resolves it…can we get some info here?

[ruchitk]

Hi,

Just had the same issue but did not have abstraction checked.

I am using oracle 10.2.0.3 DB and the latest ojdbc14.jar from oracle. It has been working OK for a while but today just suddenly it stopped generating for tables that have any single column primary keys.

The error dialogue boxes message:

An internal error occurred during: “Generating Artifacts”.
MethodInvocationException while processing template Pojo. Invocation of method ‘get’ in class com.genuitec.eclipse.hibernate.tool.hbm2x.VTemplateHelper$Templates threw exception class org.hibernate.tool.hbm2x.ExporterException : MethodInvocationException while processing template pojo/PojoPropertyAccessors.vm. Invocation of method ‘get’ in class com.genuitec.eclipse.hibernate.tool.hbm2x.VTemplateHelper$Templates threw exception class org.hibernate.tool.hbm2x.ExporterException : MethodInvocationException while processing template pojo/Ejb3PropertyGetAnnotation.vm. Invocation of method ‘generateAnnIdGenerator’ in class com.genuitec.eclipse.hibernate.wizards.MEEntityPOJOClass threw exception class java.lang.NullPointerException : null

Please help

Thanks

Try using the -clean and check if it helps:-
https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/

[ruchitk]

Hi,

I just checked my eclipse.ini file and the first line is “-clean” (I have never modified this file).
As far as I know this should do the same as running the eclipse.exe from command prompt with -clean.

I have just tried the command after starting using command prompt “eclipse.exe -clean”, but I am still having the same issue as before when trying to hibernate reverse engineer a table from the DB browser.

Please help, this is very critical to our project.

[ruchitk]

Hi

Just an update, I have reinstalled MyEclipse to see if there was any issue in my installation.

I have just finished and tried to do the hibernate reverse engineering (asking the process to Add Hibernate mappings to the POJO), and it failed with the same error message. If I allow it to create the hibernate mapping file then it seems to work without any errors.

We are using Hibernate 3.2 and I would like the mappings to be part of my POJO’s as we have a number of large tables, and it is very useful to have the mappings in the java file rather than in xml.

Awaiting your response.

[Loyal Water]

ruchitk ,
Can you switch to a new workspace (File > Switch Workspace > Temp) and test this again and let me know what result you get. You said it was working earlier so this might be an issue related to a workspace gone corrupt.

[ruchitk]

Hi Nipun

Thanks for you response, unfortunately it didn’t work:

The steps I followed are:
-Switched to a brand new workspace folder.
-Created a new project.
-Created a new DB Connection.
-Added Hibernate capabilities to the new project.
-From DB Explorer view connect to the db, navigate to the table and right-click and select “Hibernate Reverse engineering”.
While generating the POJO’s I still get the following error:

An internal error occurred during: “Generating Artifacts”.
MethodInvocationException while processing template Pojo. Invocation of method ‘get’ in class com.genuitec.eclipse.hibernate.tool.hbm2x.VTemplateHelper$Templates threw exception class org.hibernate.tool.hbm2x.ExporterException : MethodInvocationException while processing template pojo/PojoPropertyAccessors.vm. Invocation of method ‘get’ in class com.genuitec.eclipse.hibernate.tool.hbm2x.VTemplateHelper$Templates threw exception class org.hibernate.tool.hbm2x.ExporterException : MethodInvocationException while processing template pojo/Ejb3PropertyGetAnnotation.vm. Invocation of method ‘generateAnnIdGenerator’ in class com.genuitec.eclipse.hibernate.wizards.MEEntityPOJOClass threw exception class java.lang.NullPointerException : null

Are there any other ideas on what I need to do, If not I’m going to have to look for another IDE supplier.

[Ton Huisman]

Can you reveal the table structure(s)?, some fieldnames could be reserved words (like: get, class), and so causing these errors to happen.

HTH
Ton

[ruchitk]

Hi
It is an oracle db (v 10.2.0.3), I don’t think any of the fields are reserverd words (either java or oracle) but please correct me if I am wrong.
The table creation script (SQL) is below:

CREATE TABLE APP_REFERENCES
(
RF_TYPE                NUMBER(5)              NOT NULL,
RF_CODE                VARCHAR2(15 BYTE)      NOT NULL,

[Ton Huisman]

Hm, indeed, there don’t seem to be much reserved words in the above structure 😉 Must be some other ‘feature’ of hibernate that is playing up in your case.

Ton
