El código java del que dispongo es el de la clase hmpwkw01_impl.java puesto que a partir de allí se utilizan clases que están en un jar del cual no dispongo el código fuente. En la traza se menciona la línea

at hmpwkw01_impl.start1G2(hmpwkw01_impl.java:122)

que es la última de la que dispongo código fuente así que se las paso:

if ( ( GXutil.strcmp(httpContext.getRequestMethod( ), "POST") == 0 ) )

O sea que el error parte del método getRequestMethod() de la clase httpContext de la cual no dispongo código fuente.

Saludos.
