Data Adapter's subscribe() method not getting called

[CitiMan]

Adapter name is fine too, set to PORTFOLIO on both lsengine_config.js & in adapters.xml, located in root of /adapters/Portfolio folder on server. rest of the adapters.xml file is:

<?xml version="1.0"?>
<adapters_conf id="PORTFOLIO">

<metadata_provider>
<adapter_class>com.lightstreamer.adapters.metadata .LiteralBasedProvider</adapter_class>
<param name="search_dir">.</param>
<param name="max_bandwidth">16</param>
<param name="max_frequency">5</param>
<param name="buffer_size">30</param>
</metadata_provider>

<data_provider>
<adapter_class>com.lightstreamer.adapters.portfoli o.PortfolioDemoProvider</adapter_class>
<param name="config_file">portfolio.conf.properties</param>
</data_provider>

</adapters_conf>

I should maybe also point out the only difference I have in architecture is that the index.html and other js/html files are located on a tomcat server (8080) with the lightstreamer server (8081) on the same host/domain.

changed loadEngine to loadEngineMinimal and added the startEngine js function to lsPage's onEngineReady event and works fine now
