Hi Sumit,
Seems like our code is not able to fetch the Serialization policy. This is
how it looks like -
This is how doGetSerializationPolicy() iin RemoteServiceServlet looks like -
************************************
rotected SerializationPolicy doGetSerializationPolicy(
HttpServletRequest request, String moduleBaseURL, String strongName) {
// The request can tell you the path of the web app relative to the
// container root.
String contextPath = request.getContextPath();
String modulePath = null;
if (moduleBaseURL != null) {
try {
modulePath = new URL(moduleBaseURL).getPath();
} catch (MalformedURLException ex) {
// log the information, we will default
log("Malformed moduleBaseURL: " + moduleBaseURL, ex);
}
}
SerializationPolicy serializationPolicy = null;
/*
* Check that the module path must be in the same web app as the servlet
* itself. If you need to implement a scheme different than this,
override
* this method.
*/
if (modulePath == null || !modulePath.startsWith(contextPath)) {
String message = "ERROR: The module path requested, "
+ modulePath
+ ", is not in the same web application as this servlet, "
+ contextPath
+ ". Your module may not be properly configured or your client
and server code maybe out of date.";
log(message, null);
} else {
// Strip off the context path from the module base URL. It should be a
// strict prefix.
String contextRelativePath =
modulePath.substring(contextPath.length());
String serializationPolicyFilePath =
SerializationPolicyLoader.getSerializationPolicyFileName(contextRelativePath
+ strongName);
// Open the RPC resource file read its contents.
* InputStream is = getServletContext().getResourceAsStream(
serializationPolicyFilePath);* this is where the code breaks -
'is' comes out as NULL, however, it shouldn't have happened
As module is in in
the same web app as the servlet itself.
try {
if (is != null) {
try {
serializationPolicy =
SerializationPolicyLoader.loadFromStream(is,
null);
} catch (ParseException e) {
log("ERROR: Failed to parse the policy file '"
+ serializationPolicyFilePath + "'", e);
} catch (IOException e) {
log("ERROR: Could not read the policy file '"
+ serializationPolicyFilePath + "'", e);
}
} else {
String message = "ERROR: The serialization policy file '"
+ serializationPolicyFilePath
+ "' was not found; did you forget to include it in this
deployment?";
log(message, null); - this causes the log method to blow up; null
causes a NULLpointerException
}
} finally {
if (is != null) {
try {
is.close();
} catch (IOException e) {
// Ignore this error
}
}
}
}
return serializationPolicy;
}
*****************************************************
Way around this was to override the method in our local Class; we did that,
and have got it working. Though I would liek to know the exact
problem...would appreciate if you could help.
thanks,
Karan
