Here is what I did for re-initiating BPEL instances from BAM.

a) While defining the BAM sensor action, passed in the conversation Id of the instance [obtained using the xpath function ora:getConversationId()]
b) Developed a Servlet that takes in a conversationId as a request parameter and initiates a new BPEL instance with the same input message.
c) Created a table with an Action button that invokes the Servlet [using Open URL action] and passes in the conversationId.. The table contains columns that contain key identifiers for the transaction. [e.g. POId etc]
d) At runtime, users select the rows in the table based on the identifiers and click on the action button - this will re-initiate the BPEL instance.

Here is a snippet of code that does the trick.

        IBPELDomainHandle domain = null;
        Locator locator = null;
        String convId = request.getParameter("convId");

        Properties p = new Properties();
        java.net.URL url = ClassLoader.getSystemResource("context.properties");
        p.load(url.openStream());

        locator = new Locator("default","weblogic",p);
        domain = locator.lookupDomain();
        WhereCondition wc = new WhereCondition("conv_id=?");
        wc.setString(1,convId);
        IInvokeMetaData[] invMetadataArr = locator.listInvokeMessages(wc);
        IInvokeMetaData invMetadata = invMetadataArr[0];
        String messageGuid = invMetadata.getMessageGUID();
        domain.recoverInvokeMessages(new String[]{messageGuid});
