Informix Error -9450

Reasons / Common Causes

-9450 fires when a Java method invocation fails — per the official guidance.

1. The Java method not being accessible to the caller, per the official guidance — the direct, named cause; it must be either public or in the same package as the caller.

Solutions / Resolution

1. Make sure the Java method is accessible — public, or in the same package as the caller, per the official guidance.

Examples

An inaccessible (package-private) method

class MyClass {
    static int myMethod(int a) { ... }   // -9450: not public, caller in a different package
}

Corrected

public class MyClass {
    public static int myMethod(int a) { ... }
}

Diagnostic Checks

1. Check the Java method's access modifier and package relative to the calling code, and make it public if needed.
