Hi All,

anyone know how to get the source code of XF 

below i tried but its giving an null pointer error  .

private String getExperienceFragmentHtml(SlingHttpServletRequest request) throws ServletException, IOException { ResourceResolver resourceResolver = request.getResourceResolver(); Resource xfResource = request.getResource(); String xfPath = xfResource.getPath(); Page xfPage = resourceResolver.getResource(xfPath).adaptTo(Page.class); String html = ""; if (xfPage != null) { try { // Create a StringWriter to capture the HTML source code StringWriter writer = new StringWriter(); // Create a PrintWriter with the StringWriter PrintWriter printWriter = new PrintWriter(writer); // Create a new HtmlLibraryManager instance HtmlLibraryManager htmlLibraryManager = resourceResolver.adaptTo(HtmlLibraryManager.class); HtmlLibrary xfHtmlLibrary = htmlLibraryManager.getLibrary(xfPage, request); xfHtmlLibrary.include(request, printWriter, true); // Get the HTML source code from the StringWriter html = writer.toString(); } catch (Exception e) { // Handle any exceptions e.printStackTrace(); } } LOG.info("HTML" + html); return html; }

Hi @test566 ,

You can use service user to get the session so that resource can able access path, we had the same issue.

@test566 You can try like below

 

public class AemResourceResolutionServlet extends SlingSafeMethodsServlet { /** Service to create HTTP Servlet requests and responses */ @Reference private RequestResponseFactory requestResponseFactory; /** Service to process requests through Sling */ @Reference private SlingRequestProcessor requestProcessor; @Override protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException { /* The resource path to resolve. Use any selectors or extension. */ String requestPath = "<XF path>"; /* Setup request */ HttpServletRequest req = requestResponseFactory.createRequest("GET", requestPath); WCMMode.DISABLED.toRequest(req); /* Setup response */ ByteArrayOutputStream out = new ByteArrayOutputStream(); HttpServletResponse resp = requestResponseFactory.createResponse(out); /* Process request through Sling */ requestProcessor.processRequest(req, resp, request.getResourceResolver()); String html = out.toString(); } }
