Examples with AbstractSlingFilterChain org.apache.sling.engine.impl.filter.AbstractSlingFilterChain used on opensource projects

Example 1 with AbstractSlingFilterChain

use of org.apache.sling.engine.impl.filter.AbstractSlingFilterChain in project sling by apache.

the class SlingRequestProcessorImpl method handleError.

// ---------- Error Handling with Filters
void handleError(final int status, final String message, final SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {
    // wrap the response ensuring getWriter will fall back to wrapping
    // the response output stream if reset does not reset this
    response = new ErrorResponseWrapper(response);
    FilterHandle[] filters = filterManager.getFilters(FilterChainType.ERROR);
    if (filters != null && filters.length > 0) {
        FilterChain processor = new AbstractSlingFilterChain(filters) {

            @Override
            protected void render(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {
                errorHandler.handleError(status, message, request, response);
            }
        };
        request.getRequestProgressTracker().log("Applying " + FilterChainType.ERROR + " filters");
        try {
            processor.doFilter(request, response);
        } catch (ServletException se) {
            throw new SlingServletException(se);
        }
    } else {
        errorHandler.handleError(status, message, request, response);
    }
}

Example 2 with AbstractSlingFilterChain

use of org.apache.sling.engine.impl.filter.AbstractSlingFilterChain in project sling by apache.

the class SlingRequestProcessorImpl method handleError.

// just rethrow the exception as explained in the class comment
private void handleError(final Throwable throwable, final SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {
    // wrap the response ensuring getWriter will fall back to wrapping
    // the response output stream if reset does not reset this
    response = new ErrorResponseWrapper(response);
    FilterHandle[] filters = filterManager.getFilters(FilterChainType.ERROR);
    if (filters != null && filters.length > 0) {
        FilterChain processor = new AbstractSlingFilterChain(filters) {

            @Override
            protected void render(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {
                errorHandler.handleError(throwable, request, response);
            }
        };
        request.getRequestProgressTracker().log("Applying " + FilterChainType.ERROR + " filters");
        try {
            processor.doFilter(request, response);
        } catch (ServletException se) {
            throw new SlingServletException(se);
        }
    } else {
        errorHandler.handleError(throwable, request, response);
    }
