Overview
You have a JSP that is external to Aurea Process (aka CX Process, Savvion or SBM) that needs to access a document stored as a global or instance dataslot within Aurea Process as a byte stream.
Solution
You can access a document stored as a global or instance dataslot from Aurea Process as a byte stream using the BLServer and SDMS API. The following code example demonstrates how to retrieve a document from a global level document dataslot in a JSP (it is also possible to retrieve from a process instance level document dataslot):
<%@ page import="java.util.*, java.sql.Timestamp, com.savvion.sbm.bpmportal.bizsite.util.*, com.savvion.sbm.bpmportal.bizsite.api.*, com.savvion.sbm.bizlogic.client.queryservice.*,com.tdiinc.BizLogic.Server.*, com.savvion.sbm.bizlogic.client.BLClientUtil, com.savvion.sbm.bizlogic.server.ejb.BLServer, com.savvion.sbm.bizlogic.server.svo.*, com.savvion.sbm.bizlogic.util.Session, com.savvion.sbm.dms.svo.Document" %>
<%
BLClientUtil blc;
BLServer blserver = BLClientUtil.getBizLogicServer();
Session blsession = blserver.connect("ebms","ebms");
out.println("\n"+"Got Connection to BLServer..."+"\n");
// get processtemplate bl_sampleProcess object
ProcessTemplate pt = blserver.getProcessTemplate(blsession, "bl_sampleProcess");
// ask for the global dataslot name docDS
DocumentDS docObj = (DocumentDS) pt.getGlobalDataSlot("docDS");
// list of all document in the document bundle, assuming it is document bundle
List<Document> listOfDocs = docObj.getDocuments();
// Just extracting first document and getting its content below to demonstrate:
out.println("\n"+"ByteArrayInputStream to be plugged into external interface >> "+listOfDocs.get(0).getContent(docObj.getDSContext())+"\n");
%>
Note: You will need to ensure that the Aurea Process jar files and conf directory are added to your Java classpath.
Testing
Using the sample JSP code above, your external JSP is able to access the document dataslot from Aurea Process.
