Hi @jayv25585659 ,
Try below solutions:
Solution1: Use SlingRequestDispatcher (internal request)
Servlet (Example)
@Component(service = Servlet.class,
property = {
"sling.servlet.methods=GET",
"sling.servlet.paths=/bin/myservlet"
}
)
public class MyExampleServlet extends SlingSafeMethodsServlet {
@Override
protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response)
throws ServletException, IOException {
response.getWriter().write("Hello from Servlet!");
}
}
2. OSGi Component (Calling the Servlet Internally)
@Component(immediate = true, service = Runnable.class)
public class ServletCallerComponent implements Runnable {
@Reference
private SlingRequestProcessor requestProcessor;
@Reference
private ResourceResolverFactory resourceResolverFactory;
@Override
public void run() {
try (ResourceResolver resolver = resourceResolverFactory
.getServiceResourceResolver(Collections.singletonMap(
ResourceResolverFactory.SUBSERVICE, "my-service-user"))) {
HttpServletRequest request = new DummySlingHttpServletRequest(resolver, "/bin/myservlet");
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
HttpServletResponse response = new DummySlingHttpServletResponse(outputStream);
requestProcessor.processRequest(request, response, resolver);
String servletOutput = outputStream.toString(StandardCharsets.UTF_8.name());
System.out.println("Servlet Response: " + servletOutput);
} catch (Exception e) {
e.printStackTrace();
}
}
}
3. Helper Dummy Request/Response Classes
Use mock implementations or leverage Sling Mocks in testing. But for real-world use, create minimal functional mock objects or invoke via external HttpClient.
Solution2: Use HttpClient (external HTTP call)
@Activate
public void activate() {
try (CloseableHttpClient client = HttpClients.createDefault()) {
HttpGet request = new HttpGet("http://localhost:4502/bin/myservlet");
CloseableHttpResponse response = client.execute(request);
String body = EntityUtils.toString(response.getEntity());
System.out.println("Servlet Output: " + body);
} catch (IOException e) {
e.printStackTrace();
}
}
Use only if external HTTP call is acceptable (e.g., running on the same server or across instances). Otherwise prefer internal dispatch.
