Revised Execute script. Server was running out of heap space with large attachments. Creating the Document objects as temp files instead of in memory solves that. I also added the part that wipes the Base64 Attachments out of the XML.
int count = 0; Map attachmentMap = new HashMap(); String name=""; String b64Data=""; File tempFile=null; FileOutputStream outStream=null; Document attDoc=null; int i=0; Node ndAttach = (Node) patExecContext.getProcessDataValue("/process_data/xmlData/Formdata/FileAttachments"); NodeList children; Node childNode = null; if (ndAttach != null) { children = ndAttach.getChildNodes(); if (children != null) { childNode = children.item(i); if (childNode instanceof Element) { System.out.println("tag name: " + ((Element)childNode).getTagName()); } count = children.getLength(); } } for (i = 1; i <= count; i++){ b64Data = patExecContext.getProcessDataStringValue("/process_data/xmlData/Formdata/FileAttachments/FileAttachment[" + i + "]/Base64Data"); if (b64Data != null && b64Data.length() != 0) { name = patExecContext.getProcessDataStringValue("/process_data/xmlData/Formdata/FileAttachments/FileAttachment[" + i + "]/FileName"); tempFile = File.createTempFile("Attachment", ".tmp"); outStream = new FileOutputStream(tempFile); outStream.write(Base64.decodeBase64(b64Data.getBytes())); outStream.close(); attDoc = new Document(tempFile, true); attDoc.setAttribute("basename", name); attDoc.setAttribute("description", patExecContext.getProcessDataStringValue("/process_data/xmlData/Formdata/FileAttachments/FileAttachment[" + i + "]/FileDesc")); attDoc.setAttribute("wsPermission", "1"); attachmentMap.put(name, attDoc); } } patExecContext.setProcessDataMapValue("/process_data/mapAttachments", attachmentMap); while (ndAttach.hasChildNodes()) { ndAttach.removeChild(ndAttach.getLastChild()); }
