SQL4300 - SQL4399

SQL4300N Java support is not installed on this platform.

Cause: Support for Java stored procedures and user-defined functions is not installed and configured on this server.

Action: Ensure that a compatible Java Runtime Environment or Java Development Kit for the server is installed. Ensure that the "jdk11_path" configuration parameter is correctly set.

SQL4301N Java interpreter startup or communication failed, reason code "<reason-code>".

Cause: An error occurred while attempting to start or communicate with a Java interpreter. The reason codes are:

1: Java environment variables or Java database configuration parameters are invalid.
2: A Java Native Interface call to the Java interpreter failed.
3: The "db2java.zip" file may be corrupt or missing.
4: The Java interpreter has terminated itself and cannot be restarted.

Action: Ensure that the Java database configuration parameters (jdk11_path and java_heap_sz) are correctly set. Ensure that a supported Java runtime environment is installed. Ensure that internal DB2 classes (COM.ibm.db2) are not overridden by user classes.

SQL4302N Java stored procedure or user-defined function "<name>", specific name "<spec-name>" aborted with an exception "<string>".

Cause: The Java stored procedure or user-defined function aborted with a Java exception. The First Failure Service Log (db2diag.log) contains a Java stack traceback for the aborted method.

Action: Debug the Java method to eliminate the exception.

SQL4303N Java stored procedure or user-defined function "<name>", specific name "<spec-name>" could not be identified from external name "<string>".

Cause: The CREATE PROCEDURE or CREATE FUNCTION statement that declared this stored procedure or user-defined function had a badly formatted EXTERNAL NAME clause. The external name must be formatted as follows: "package.subpackage.class!method".

Action: Submit a corrected CREATE PROCEDURE or CREATE FUNCTION statement.

SQL4304N Java stored procedure or user-defined function "<name>", specific name "<spec-name>" could not load Java class "<class>", reason code "<reason-code>".

Cause: The Java class given by the EXTERNAL NAME clause of a CREATE PROCEDURE or CREATE FUNCTION statement could not be loaded. The reason codes are:

1: The class was not found on the CLASSPATH.
2: The class did not implement the required interface ("COM.ibm.db2.app.StoredProc" or "COM.ibm.db2.app.UDF") or lacked the Java "public" access flag.
3: The default constructor failed or was unavailable.

Action: Ensure that the compiled ".class" file is installed in the CLASSPATH, for example under "sqllib/function". Ensure it implements the required Java interfaces and is "public".

SQL4306N Java stored procedure or user-defined function "<name>", specific name "<spec-name>" could not call Java method "<method>", signature "<string>".

Cause: The Java method given by the EXTERNAL NAME clause of a CREATE PROCEDURE or CREATE FUNCTION statement could not be found. Its declared argument list may not match what the database expects, or it may not be a "public" instance method.

Action: Ensure that a Java instance method exists with the "public" flag and the expected argument list for this call.
