Hi Experts:

Opted to post this in this java boards instead of pl/sql.. Hope i did the right thing.. Anyway i'm just clueless right now..

I was given this java class / java file:

> Myclass.class

- takes and input like this:

public class Myclass {
  public static void main(String[] args) {
  .
  .
  .
  }
}


- though it calls a package and other classes, and most likely these other classes are the ones returning a string output.

and i did these steps:


$ loadjava -user arbor Myclass.class
Password: password


SQL> EXECUTE DBMS_JAVA.GRANT_PERMISSION ('MYSHEMA', 'SYS:java.io.FilePermission', '<<ALL FILES>>', 'execute' )

PL/SQL procedure successfully completed.

SQL> EXECUTE DBMS_JAVA.GRANT_PERMISSION ('MYSHEMA', 'java.lang.RuntimePermission', '*', 'writeFileDescriptor' )

PL/SQL procedure successfully completed.

SQL> EXECUTE DBMS_JAVA.GRANT_PERMISSION ('MYSHEMA', 'java.lang.RuntimePermission', '*', 'readFileDescriptor' )

PL/SQL procedure successfully completed.

-----

SQL> create or replace procedure Myclass_Proc (p_args IN VARCHAR2)
  2  AS LANGUAGE JAVA
  3  NAME 'Myclass(java.lang.String)';
  4  /

Warning: Procedure created with compilation errors.

3/1      PLS-00311: the declaration of "Myclass(java.lang.String)"
         is incomplete or malformed

-----

-- i also did these:

SQL> create or replace function Myclass_Func (p_args IN VARCHAR2)
  2  RETURN VARCHAR2 AS LANGUAGE JAVA
  3  NAME 'Myclass(java.lang.String) return java.lang.String';
  4  /

Dont know if my error is on java or pl/sql, but most likely its in my format.. im just clueless right now, if you could help or suggest something i would really appreciate it..

Wilbert

Should be something like:
create or replace function Myclass_Func (p_args IN VARCHAR2)
RETURN VARCHAR2 AS LANGUAGE JAVA
NAME 'Myclass.Myfunction(java.lang.String) return java.lang.String';
/

Hi Michel C.,

Its seems there aren't any other function in the Myclass.class file.. just the main() and SEVERAL other import package.classes.. too bad i cant really post the java code itself in this thread, it would cause me alot of trouble..

even tried it this way:

SQL> create or replace function Myclass_Func (p_args IN VARCHAR2)
  2  RETURN VARCHAR2 AS LANGUAGE JAVA
  3  NAME 'Myclass.main(java.lang.String) return java.lang.String';
  4  /

Warning: Function created with compilation errors.

SQL> sho err
Errors for FUNCTION MYCLASS_FUNC:

LINE/COL ERROR
-------- -----------------------------------------------------------------
0/0      PL/SQL: Compilation unit analysis terminated
3/1      PLS-00311: the declaration of "Myclass(java.lang.String) return java.lang.String"
         is incomplete or malformed


i'm still looking into this java Myclass.class file, if i was the one who created it, it would much easier to debug, oh well these scenarios cant be helped in this line of work...

Regards,
Wilbert

"main" does not return a string. It is a procedure not a function from what you posted.

Note: You can always post a test case that reproduces your issue.

In addition, main does not have String as parameter, but String[]
