Usage

From source file:org.gridgain.grid.GridFactory.java

/**
 * Starts all grids specified within given Spring XML configuration file URL. If grid with given name
 * is already started, then exception is thrown. In this case all instances that may
 * have been started so far will be stopped too.
 * <p>// ww  w  .j a va 2 s .c  o m
 * Usually Spring XML configuration file will contain only one Grid definition. Note that
 * Grid configuration bean(s) is retrieved form configuration file by type, so the name of
 * the Grid configuration bean is ignored.
 *
 * @param springCfgUrl Spring XML configuration file URL. This cannot be {@code null}.
 * @param ctx Optional Spring application context.
 * @return Started grid. If Spring configuration contains multiple grid instances,
 *      then the 1st found instance is returned.
 * @throws GridException If grid could not be started or configuration
 *      read. This exception will be thrown also if grid with given name has already
 *      been started or Spring XML configuration file is invalid.
