Oracle - Java/JSERVER - Debug Load / Compilation

Card Puncher Data Processing


When you load Java unit, you can get such error:

java.sql.SQLException: ORA-24344: success with compilation error
ORA-06512: at line 1

	at oracle.jdbc.driver.SQLStateMapping.newSQLException(
	at oracle.jdbc.driver.DatabaseError.newSQLException(
	at oracle.jdbc.driver.DatabaseError.throwSqlException(
	at oracle.jdbc.driver.T4CTTIoer.processError(

How can we resolve this error ?

How to get the error ?

select name, type, sequence, substr(text,0,100) from user_errors;

Salesforce“JAVA SOURCE”31“ nbSeparator = nbSeparator - 1;”
Salesforce“JAVAOURCE”32“ ”
Salesforce“JAVA SOURCE”33“8 errors”

Solution in this case: change integer with int in the java class

Integer countLine = 0;

was become

int countLine = 0;

How to resolve the java class ?

First, get the correct name of the object:

select object_name, object_type, status
from user_objects
where object_type like '%JAVA%';

Then resolve it:

Before resolution of the problem:

SQL> alter java class "com/gerardnico/Salesforce" resolve;

Warning: Java altered with compilation errors.

After the resolution:

SQL> alter java class "com/gerardnico/Salesforce" resolve;

Java altered.

Redirecting the output to SQL*Plus Text Buffer

As in previous releases, you can use the DBMS_JAVA package procedure SET_OUTPUT to redirect output to the SQL*Plus text buffer:

CALL dbms_java.set_output(2000);

The minimum and default buffer size is 2,000 bytes and the maximum size is 1,000,000 bytes. In the following example, the buffer size is increased to 5,000 bytes:

SQL> CALL dbms_java.set_output(5000);

The output is displayed at the end of the call.

Example of result:

SQL> call AlterSalesforceFile();
AlterSalesforceFile started
Error: the Permission ( /transfer/salesforce_original read) 
has not been granted to STG. The PL/SQL to grant this is dbms_java.grant_permission( 'STG', 
'', '/transfer/salesforce_original', 'read' )

Call completed.
