#Preauthorize in GWT - java

I'm writting my application using GWT. There're two roles (ROLE_USER and ROLE_ADMIN) in my app. ROLE_ADMIN has access to some handler
#Service
#PreAuthorize("hasAnyRole('ROLE_ADMIN')")
public class GetAuditDataListHandler extends AbstractActionHandler<GetAuditDataListAction, GetAuditDataListResult> {
// Code here
}
When I try to access under ROLE_USER I want to show dialogbox ("Access denied!"). But it returns 500 The call failed on the server; see server log for details

Spring will be checking the security roles and throwing an exception before executing the handler.
You would normally be able to catch this exception in the client onFailure() method of the Request but the exception thrown may not be serialisable or most likely not available to the GWT client side code and cannot be serialised - leading to the error.
It looks like you are using the gwt-dispatch library? I haven't used this for some time but you can override the SpringSecureDispatchServlet and add your own implementation of the doUnexpectedFailure(Throwable e) method. In there you could check the exception to see if it is a Spring security exception and instead of calling RPCServletUtils.writeResponseForUnexpectedFailure(...) that returns a status code of 500 implement your own that returns a more suitable error code (401, or 403).


Couldn't you add a Servlet Filter to catch this particular exception and turn it into the HTTP response you would like?

Unable to Validate Json Schema in rest assured

I am using rest assured and validating JSON schema using it. I generated the schema using jsonschema.net(draft 7) and saved the generated schema in the file and matched the generated schema against the response of GET API.

my genereated schema is schema link
Repsonse of the api API repsonse

Maybe the current REST Assured library work until draft 4. I'm using json-schema-generator tool to generate json schema in draft 4 and able to validate the response.
Commands to install and generate schema: -
npm install -g json-schema-generator
json-schema-generator path/to/input_response.json -o path/to/json_schema.json

Could someone help me, I'm very difficult to find a solution for this problem!!

This has been resolved. I ended up generating my own web service proxy services for the TaskService, instead of using the one that was bundled with jDeveloper. So honestly speaking, because of time constraints, I did not get a chance to fix the exact root cause of this error. After generating this webservice proxy/stub, i bundled it as a shared webapp library and my Custom Worklist portlet refers to this library. This worked for me.
I used this WSDL to generate the proxy classes and then used the generated classes/methods to query tasks data.
http://soa_host:soa_port/integration/services/TaskQueryService/TaskQueryService?wsdl
Also, later taking the original case forward, I was also able to get around the token problem by using RMI/EBJ provider ( t3://: ) instead of SOAP binding (http://:).
Here's what my code looks like :
String serverUrl ="t3://soa_server:soa_port"; // host:Port of the soa server
Map<IWorkflowServiceClientConstants.CONNECTION_PROPERTY, String> connProperties = new HashMap<IWorkflowServiceClientConstants.CONNECTION_PROPERTY, String>();
connProperties.put(IWorkflowServiceClientConstants.CONNECTION_PROPERTY.CLIENT_TYPE,WorkflowServiceClientFactory.REMOTE_CLIENT);
connProperties.put(IWorkflowServiceClientConstants.CONNECTION_PROPERTY.EJB_PROVIDER_URL,serverUrl);
connProperties.put(IWorkflowServiceClientConstants.CONNECTION_PROPERTY.EJB_INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
IWorkflowServiceClient wfSvcClient = WorkflowServiceClientFactory.getWorkflowServiceClient(connProperties, null, null);
ITaskQueryService querySvc = wfSvcClient.getTaskQueryService();
IWorkflowContext adminCtx = wfSvcClient.getTaskQueryService().authenticate(adminID, adminPass.toCharArray(), "jazn.com" );
IWorkflowContext userCtx = querySvc.authenticateOnBehalfOf(adminCtx, userID);
List displayColumns = new ArrayList();
displayColumns.add("TASKNUMBER");
displayColumns.add("TITLE");
displayColumns.add("STATE");
displayColumns.add("CREATOR");
List optionalInfo = new ArrayList();
optionalInfo.add("Comments");
optionalInfo.add("Payload");
tasks=querySvc.queryTasks(userCtx, null, null, ITaskQueryService.AssignmentFilter.MY,null, null, null, 0, 0);
This returns list of tasks assigned to the user whose ID you send to authenticateOnBehalfOf() method call above.
I hope this helps.

Below solution from Oracle Support Documentation fixed the issue for me. In summary, it's a jar mismatch between server and jdev that caused the issue.

Also, If you log the username from the context you'll notice it is null.
Cause
The bpm-services.jar on the client application and the server may not match. The SOA/BPM related jars being used on the client and server must be the same or unexpected issues can occur.
Solution
Copy the bpm-services.jar from the server
Replace the bpm-services.jar on the client application with the one from the server
Ensure that after any patches are applied that the jars on the server are replaced in the client application.
This also applies to using jars within JDeveloper which can become out of sync due to patches not being applied on both dev and server machines. You may need to replace the bpm-services.jar located here JDeveloper/soa/modules/oracle.soa.workflow_11.1.1/bpm-services.jar with the one located here [soa_install_dir]/soa/modules/oracle.soa.workflow_11.1.1/bpm-services.jar.

GWT Maps Icon.NewInstance intermittently throwing exception

I'm creating a custom icon to use as a marker on a map, and intermittently, but quite often this function:
private Icon createIcon(String Url) {
Icon icon = Icon.newInstance(Url); //<-- This line throws exception
icon.setIconSize(Size.newInstance(30, 30));
icon.setIconAnchor(Point.newInstance(6, 20));
icon.setInfoWindowAnchor(Point.newInstance(14, 4));
return icon;
}
throws this exception:

Does anybody have any insight as to why this happens and what I can do to fix this behavior?

This ended up being a concurrency issue where the map was not finished loading when the icons were trying to be generated. When I moved some code around so it only ran after the Maps asynchronous load was finished this issue went away.

Gwtp NullpointerException- annotation

I am trying to implement a mobileweb app using Gwtp. I have the desktop and tablet view working but i get an error for mobile view. I am binding 3 different presenters for desktop, mobile and tablet view. So it will be a different landing page on different devices. I need different landing page functionality on different devices. The first presenter on a tablet will be a list of tasks, but on a mobile the user has to login first to see the list of tasks. Also, some of the presenters will be shared by a tablet and mobile view.
MobileModule-
bindConstant().annotatedWith(DefaultPlace.class).to(NameTokens.login);
bindPresenter(LoginPresenter.class, LoginPresenter.MyView.class,
LoginView.class, LoginPresenter.MyProxy.class);
bindPresenter(MainListTabletPresenter.class,
MainListTabletPresenter.MyView.class, MainListMobileView.class,
MainListTabletPresenter.MyProxy.class);
TabletModule-
bindConstant().annotatedWith(DefaultPlace.class).to(NameTokens.mainList);
bindPresenter(MainListTabletPresenter.class,
MainListTabletPresenter.MyView.class, MainListTabletView.class,
MainListTabletPresenter.MyProxy.class);
bindPresenter(LoginPresenter.class, LoginPresenter.MyView.class,
LoginView.class, LoginPresenter.MyProxy.class);
Any ideas why i would get the following (NullpointerException about annotations), when i run the application? I think i have the annotations correct for the LoginPresenter.

Please let me know whats the problem......of this error....thanx in advance
Ya....all of you are right ....But what i am getting is that it is an SOAP request and i have already see the request carefully there is no bad character.....But the problem is that when i am invoking the web service through soap request it gives null as a respone so i am getting the error.....
As soon as Webservice work properly ......this works fine now....thanks all of you

It means that there is something in xml before <?xml ... look carefully in it. Also check that there is no invisible character (you can do it in any HEX editor). Sometimes windows notepad adds his marker in the file beginning.

The parser sees character data before the actual XML itself is started. Either make sure your XML does not contain any stuff before the XML starts, or let your SAX parser ignore this...

Try to display the data you're actually parsing. Maybe some bad characters are inserted before the beginning of your xml, or maybe you're not reading the right file.

This may be a because of a BOM, if your XML file is stored as UTF-8 (which it probably is).
Here, you have an example of an InputStream, that gets rid of the BOM.
