CONIMEX is a Dutch based Indonesian foods brand that does produce Sambal Badjak. I have seen their Sambal Olek, Ketjaps and packaged goods in Kensington Market (House of Spice etc.) and downstairs at the St Lawrence Market. Their ketjap manis isn't much like ABC brand's (the king of ketjap), but their sambal olek is a reasonable copy of the real thing. Those stores may be able to help.
Below is a link to a Dutch Products website that has Indonesian products available.
