How to program availability check and to create new meeting to Outlook?

I am creating a Java web app to manage meetings between a set of students and teachers. All of them already use Outlook to manage their email and personal calendar.
I would like to know if it's even possible to build the schedule feature of my web app using Exchange, Office365 or Sharepoint Team Calendar via REST service in order to check the availability and create a meeting for a student and one of the teachers available:
SharePoint 2013 REST service
So far, the most promising mechanism I have found is Microsoft Sharepoint Server's calendar, which collaborative features makes possible to create a meeting and check availability for a list of users. The downside is that it does not support one to one meetings but for the entire team (as far I have found).
My second option would be to require everyone in the group (students and teachers of the department) to make public their personal calendar so the web app be able to check the availability of both student and teacher and send a meeting request. The obvious problem is the privacy/security concern derived from this approach.
My last option (and by far the less favourite because it feels like re-inventing the wheel) is to build a proprietary calendar within the web app and send iCal requests to each person. The obvious problem with this approach is synchronisation between the two separated calendars.
In addition, this feature must be a pretty common need so there should be tons of blogs explaining how to take advantage of Exchange/Sharepoint/Office365 to implement it (other platforms are not considered since my employer's infrastructure is based on Microsoft). However, whether it is so obvious that nobody talks about it or I have not searched in the right place. Any advice to point me in the right direction?

Exchange natively shows user calendar availability exposed in EWS (Exchange Web Services), your network administrator must configure Exchange server enabling EWS.
But guess what... Office 365 (as I know) have EWS services enabled, due exchange is part of office 365 offer.
As EWS are normal Web services you should create a "service stub" or proxy in whatever you use in java to create services references mapping wsdl files.
Exchanged EWS is my preferred solution.
Hope this helps.
This is the reference page, this link show how to use the service references from C# to make the right API calls.

Calling Microsoft Dynamics CRM 2011 online from JAVA

I'm doing a Dynamics CRM integration from a Java application and I've followed the example from the CRM training kit and managed successfully to connect and create accounts and contacts.
Now I'm having some problems with adding some more fields in the account creation and when connecting a contact with an account.
For instance I cannot create accounts with "address1_freighttermscode" that is a picklist.
My code is the following:
private static OrganizationServiceStub.Guid createAccount(OrganizationServiceStub serviceStub, String[] args) {
try {
OrganizationServiceStub.Create entry = new OrganizationServiceStub.Create();
OrganizationServiceStub.Entity newEntryInfo = new OrganizationServiceStub.Entity();
OrganizationServiceStub.AttributeCollection collection = new OrganizationServiceStub.AttributeCollection();
if (! (args[0].equals("null") )) {
OrganizationServiceStub.KeyValuePairOfstringanyType values = new OrganizationServiceStub.KeyValuePairOfstringanyType();
values.setKey("name");
values.setValue(args[0]);
collection.addKeyValuePairOfstringanyType(values);
}
if (! (args[13].equals("null"))){
OrganizationServiceStub.KeyValuePairOfstringanyType incoterm = new OrganizationServiceStub.KeyValuePairOfstringanyType();
incoterm.setKey("address1_freighttermscode");
incoterm.setValue(args[13]);
collection.addKeyValuePairOfstringanyType(incoterm);
}
newEntryInfo.setAttributes(collection);
newEntryInfo.setLogicalName("account");
entry.setEntity(newEntryInfo);
OrganizationServiceStub.CreateResponse createResponse = serviceStub.create(entry);
OrganizationServiceStub.Guid createResultGuid = createResponse.getCreateResult();
System.out.println("New Account GUID: " + createResultGuid.getGuid());
return createResultGuid;
} catch (IOrganizationService_Create_OrganizationServiceFaultFault_FaultMessage e) {
logger.error(e.getMessage());
} catch (RemoteException e) {
logger.error(e.getMessage());
}
return null;
}
When it executes, I get this error
[ERROR] Incorrect attribute value type System.String
Does anyone have examples on how to handle picklists or lookups?
To connect the contact with the account I'm filling the fields parentcustomerid and parentcustomeridtype with the GUID from the account and with "account", but the contact does not get associated with the account.

To set a picklist value you must use an OptionSet and for a lookup you must use an EntityReference. See the SDK's C# documentation, should work the same way using the Axis generated Java code.
incoterm.setKey("address1_freighttermscode")
//assuming the arg is an integer value that matches a picklist value for the attribute
OptionSetValue freight = new OptionSetValue();
freight.Value = args[13];
incoterm.setValue(freight);
collection.addKeyValuePairOfstringanyType(incoterm);

I haven't worked with Java for over a decade (and never towards an MS creation like Dynamics) so it might be way off from what you like. :)
You could use the REST web service and call directly to CRM creating your instances. As far I know, that's platform independent and should work as long as you can connect to the exposed service OrganizationData.

insert a domain name into servlet authentication token

I am using Waffle for an SSO solution in my web-app.
Everything works fine but I would like to modify some functionality slightly:
Currently, if a user is not connected to the domain the SSO fails and opens a little authorization dialog:
The windows authorization requires the user name formatted like Domain\Username but most of my users will not know to add the domain in front of their username. So I would like to provide a default domain name if one is not specified.
I found a waffle function that I can override which will give me access to the decoded authentication token, I added a println to the waffle function and it shows the username in plain text (either with or without the domain depending on what is typed in the dialog):
public IWindowsSecurityContext acceptSecurityToken(String connectionId, byte[] token, String securityPackage) {
// I can see the passed username in the logs with this
System.out.println(new String(token));
// I don't understand any of the JNA stuff below this comment:
IWindowsCredentialsHandle serverCredential = new WindowsCredentialsHandleImpl(
null, Sspi.SECPKG_CRED_INBOUND, securityPackage);
serverCredential.initialize();
SecBufferDesc pbServerToken = new SecBufferDesc(Sspi.SECBUFFER_TOKEN, Sspi.MAX_TOKEN_SIZE);
SecBufferDesc pbClientToken = new SecBufferDesc(Sspi.SECBUFFER_TOKEN, token);
NativeLongByReference pfClientContextAttr = new NativeLongByReference();
CtxtHandle continueContext = _continueContexts.get(connectionId);
CtxtHandle phNewServerContext = new CtxtHandle();
int rc = Secur32.INSTANCE.AcceptSecurityContext(serverCredential.getHandle(),
continueContext, pbClientToken, new NativeLong(Sspi.ISC_REQ_CONNECTION),
new NativeLong(Sspi.SECURITY_NATIVE_DREP), phNewServerContext,
pbServerToken, pfClientContextAttr, null);
WindowsSecurityContextImpl sc = new WindowsSecurityContextImpl();
sc.setCredentialsHandle(serverCredential.getHandle());
sc.setSecurityPackage(securityPackage);
sc.setSecurityContext(phNewServerContext);
switch (rc)
{
case W32Errors.SEC_E_OK:
// the security context received from the client was accepted
_continueContexts.remove(connectionId);
// if an output token was generated by the function, it must be sent to the client process
if (pbServerToken != null
&& pbServerToken.pBuffers != null
&& pbServerToken.cBuffers.intValue() == 1
&& pbServerToken.pBuffers[0].cbBuffer.intValue() > 0) {
sc.setToken(pbServerToken.getBytes());
}
sc.setContinue(false);
break;
case W32Errors.SEC_I_CONTINUE_NEEDED:
// the server must send the output token to the client and wait for a returned token
_continueContexts.put(connectionId, phNewServerContext);
sc.setToken(pbServerToken.getBytes());
sc.setContinue(true);
break;
default:
sc.dispose();
WindowsSecurityContextImpl.dispose(continueContext);
_continueContexts.remove(connectionId);
throw new Win32Exception(rc);
}
return sc;
}
That whole function is from the Waffle API I only added the println at the beginning.
The passed username prints in plain text inside this token between a bunch of random byte chars (ÉsR=ÍtÍö?æ¸+Û-).
I am admittedly in very far over my head with JNA and java in general but I thought that because I can see the username here there must be a way to prepend the domain name to the username part of this token? I could be wrong.
My other idea was to add the domain to the pbClientToken that is created from the raw byte[] token this method is passed.
The pbClientToken is a JNA Structure object derivative. It has the Stucture method writeField which looked promising but I can't seem to figure out what field I should write. The Structure.getFields method doesn't seem to be available from pbClientToken.
I was hoping that this was a simple problem for someone more familiar with byte[] processing or JNA.

You cannot do this. What happens behind this dialog is a call to LogonUser on the user's machine, which gives you a ticket, which is then sent to the server. Unfortunately the server is not in the same domain, so even if you manage to extract the username it's completely useless.

How to get data via MBean

I'm implementing a servlet as a JMX manager that runs in the same instance of Tomcat that all of the monitored servlets are running in. I can see the data of the monitored servlets when I open JConsole. From within my manager servlet I can enumerate all of the available standard MBeans, including the ones I've created in the monitored servlets, using this code like this:
JMXServiceURL url = new JMXServiceURL( "service:jmx:rmi://localhost:1099/jndi/rmi://localhost:1099/jmxrmi" );
mConnector = JMXConnectorFactory.connect( url );
mMBSC = mConnector.getMBeanServerConnection();
mObjectName = new ObjectName( "com.blahCompany.blah.blah:type=BlahBlah" );
// just looking for one specific bean
Set<ObjectName> myMbean = mMBSC.queryNames( mObjectName, null );
if( myMBean.size() == 1 ) // I know it exists
{
MBeanInfo mbeanInfo = mMBSC.getMBeanInfo( <ObjectName extracted from Set> );
MBeanAttributeInfo[] mbeanAttributeInfos = mbeanInfo.getAttributes();
for( MBeanAttributeInfo attribInfo : mbeanAttributeInfos )
{
if( attribInfo.isReadable() )
{
String attribName = attribInfo.getName();
String attribReturnType = attribInfo.getType();
// The data's somewhere ... where????
// In the MBeanInfo?
// In the MBeanAttributeInfo??
}
}
}
The problem is I don't know how to actually extract the data from these MBeans. The answer must be godawful obvious because no one else seems to have asked, but I do have a gift for overlooking the obvious. Your help will be gratefully appreciated.
Bill

All you need to do is something like the below:
Object value = mMBSC.getAttribute(objectName, attributeName);
Or create a proxy object that gets an instance of the MBean interface and allows you to access it that way. A tutorial on how to do this is here: http://docs.oracle.com/javase/tutorial/jmx/remote/custom.html
One note, this is assuming a remote connection, but from your question it seems your are accessing the beans locally? If that is the case then you can use platform.getMBeanServer() to get access to the MBeanServer more directly. E.g. MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();

AMF client in Java

I am using BlazeDS java client to get info from this page.
This page has a form in the middle that when you select a type, the location combo on the button gets updated.
I am trying to use BlazeDS to get those values in java.
I have been using Charles web proxy to debug, and this are the screenshots from the request and the response:
My code so far is the following:
// Create the AMF connection.
AMFConnection amfConnection = new AMFConnection();
// Connect to the remote url.
String url = "http://orlandoinfo.com/flex2gateway/";
try
{
amfConnection.connect(url);
}
catch (ClientStatusException cse)
{
System.out.println(cse);
return;
}
// Make a remoting call and retrieve the result.
try
{
// amfConnection.registerAlias("flex.messaging.io.ArrayCollection", "flex.messaging.io.ArrayCollection");
amfConnection.call("ColdFusion.getLocations", new Object[] {"consumer", "attractions", "ATTR"});
}
catch (ClientStatusException cse)
{
System.out.println(cse);
}
catch (ServerStatusException sse)
{
System.out.println(sse);
}
// Close the connection.
amfConnection.close();
When I run it I get a:
ServerStatusException
data: ASObject(15401342){message=Unable to find source to invoke, rootCause=null, details=null, code=Server.Processing}
HttpResponseInfo: HttpResponseInfo
code: 200
message: OK
Can anyone spot what's wrong?
Thanks for reading!

I ended up using Charles Web Proxy. Sniffing AMF parameters and running my code with -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8888
I compare both calls and modify to look alike.
The working code looks like this:
String url = "http://www.theGateWayurl.com";
// Generates the connection to the amf gateway.
AMFConnection amfConnection = new AMFConnection();
// Must register the class that this library will use to load the
// AMF object information.
// The library will read AMF object variables and use setters from
// the java bean stated in this line.
AMFConnection.registerAlias("", new LabelData().getClass().getName());
try {
// Do the connection.
amfConnection.connect(url);
// This page requires a certain headers to function.
// The Content-type is used to sniff with Charles Web Proxy.
amfConnection.addHttpRequestHeader("Content-type", "application/x-amf");
// The Referer is used by the webpage to allow gathering information.
amfConnection.addHttpRequestHeader("Referer", "http://orlandoinfo.com/ws/b2c/sitesearch/customtags/comSearch.swf");
// The rest of the HTTP POST sent by this library is wrapped
// inside a RemotingMessage.
// Prepare the msg to send.
RemotingMessage msg = new RemotingMessage();
// The method called in the server.
msg.setOperation("getLocations");
// Where the request came from. Similar to referer.
msg.setSource("ws.b2c.sitesearch.components.myService");
// The destination is a needed parameter.
msg.setDestination("ColdFusion");
// Create the body with the parameters needed to call the
// operation set with setOperation()
msg.setBody(new Object[] {"consumer", "attractions"});
// This is needed but not used.
msg.setMessageId("xxxxxxxxxx");
// Send the msg.
AcknowledgeMessage reply = (AcknowledgeMessage) amfConnection.call("null", msg);
// Parse the reply from the server.
ArrayCollection body = (ArrayCollection) reply.getBody();
for (Object obj : body) {
LabelData location = (LabelData) obj;
// Do something with the info.
}
} catch (ClientStatusException cse) {
// Do something with the exception.
} catch (ServerStatusException sse) {
// Do something with the exception.
} finally {
amfConnection.close();
}
The LabelData is just a java bean with with two vars: Data and Label.
I tried to comment every line for a better understanding.
Take into account what Stu mention in previous comments about crossdomain.xml to see if you have the rights to do this kind of things.
