use of org.apache.cocoon.pipeline.component.sax.XMLSerializer in project sling by apache.

the class PipelineImpl method eval.

@Override

            step.eval();
        }
        this.getEnv().getCcPipeline().addComponent(new XMLSerializer());
        // Don't retrieve OutputStream from response until actually writing
        // to response, so that error handlers can retrieve it without getting
        // an error
