I moved the code to the java class that invoked by the JSP page.
The implementation is as follows.
BrokerClient.java
===============================
public void publish(String topic, String message) throws AxisFault,
XMLStreamException {
log.debug("published element to " + topic);
StAXOMBuilder builder = new StAXOMBuilder(new
ByteArrayInputStream(message.getBytes()));
OMElement omElementMessage = builder.getDocumentElement();
EventBrokerServiceStub service = new
EventBrokerServiceStub(configurationContext, brokerUrl + "/publish/" +
topic);
configureCookie(service._getServiceClient());
ServiceClient serviceClient = service._getServiceClient();
OMElement header = fac.createOMElement(new QName(TOPIC_HEADER_NS,
TOPIC_HEADER_NAME));
header.setText(topic);
serviceClient.addHeader(header);
serviceClient.getOptions().setTo(new EndpointReference(brokerUrl +
"/publish"));
//serviceClient.getOptions().setTo(new
EndpointReference(brokerUrl));
serviceClient.getOptions().setAction("urn:publish");
serviceClient.sendRobust(omElementMessage);
}
The relevant JSP page code
===============================
<%@ page import="org.apache.axiom.om.OMElement" %>
<%@ page import="org.apache.axiom.om.impl.builder.StAXOMBuilder" %>
<%@ page import="org.wso2.carbon.event.client.broker.BrokerClient" %>
<%@ page import="org.wso2.carbon.event.ui.UIUtils" %>
<%@ page import="java.io.ByteArrayInputStream" %>
<%
BrokerClient brokerClient = UIUtils.getBrokerClient(config, session,
request);
String topic = request.getParameter("topic");
String textMsg = request.getParameter("xmlMessage");
session.setAttribute("errorTopic", topic);
session.setAttribute("xmlMessage", textMsg);
String messageToBePrinted = null;
try {
brokerClient.publish(topic, textMsg);
} catch (Exception e) {
messageToBePrinted = "Error: while publishing the message " +
e.getMessage();
}
if (messageToBePrinted == null) {
messageToBePrinted = "Successfully published the message to the
topic :" + topic;
}
%>
<%=messageToBePrinted%>
But I am getting the following error now.
=============== Error =================
org.apache.jasper.JasperException: Unable to compile class for JSP:

Any help on this would be appreciated.
