从Java存储过程调用主函数

Question

I have loaded the class file of a java program (that fetches data from an excel file and pushes it to a database and making connection to database using values from properties file) into the SQL developer.

Now I am trying to invoke the main method of the class file as below:

CREATE OR REPLACE PROCEDURE dataset
AS LANGUAGE JAVA
NAME 'data_design_1.main()';

It gives the following error:

Error: PL/SQL: Compilation unit analysis terminated
Error(3,1): PLS-00311: the declaration of "data_design_1.main()" is incomplete or malformed

Could anyone tell me why is this error occurring??

Thank you.

Answer 1

I think that the declaration of your main is this

public static void main(String[] args)

so the declaration of your PL/SQL wrapper is wrong.

You haven't posted the Java code Maybe I'm wrong.
