Issue with storing image files for profile pictures

I'm doing a coursework project for university and I'm in charge of getting the profile system functioning. Our lecturer has given us some sample code to get a file-upload working which I'm going to use for the user's profile picture however even though my code looks to be very similar I just can't seem to get it working. The issue is that the file won't actually create and save in my project, yet the code my lecturer gave me does!
Here is the code the lecturer gave me:
NewsStory newsstory = new NewsStory();
newsstory.uniqueid = "story_"+System.currentTimeMillis();
newsstory.dateItWasPublished = System.currentTimeMillis();
newsstory.title = toProcess.params.get("title");
newsstory.description = toProcess.params.get("description");
newsstory.journalists.add(toProcess.params.get("journalist"));
newsstory.filepathToImage = toProcess.params.get("fileupload");
File uploaded = new File(newsstory.filepathToImage);
int ind = newsstory.filepathToImage.lastIndexOf('.');
String extension = newsstory.filepathToImage.substring(ind);
uploaded.renameTo(new File("httpdocs/"+newsstory.uniqueid+extension));
newsstory.filepathToImage = newsstory.uniqueid+extension;
//At this point you would normally add the newsstory to the database
MVMap<String, NewsStory> newsStories = db.s.openMap("NewsStories");
newsStories.put(newsstory.uniqueid, newsstory);
This basically takes in a String from a fileupload paramater passed in through a form and runs the code below. Here is my code:
user.userEmail = toProcess.params.get("email");
user.profilePicturePath = toProcess.params.get("filepath");
System.out.println(user.profilePicturePath);
File uploaded = new File(user.profilePicturePath);
int ind = user.profilePicturePath.lastIndexOf('.');
String extension = user.profilePicturePath.substring(ind);
uploaded.renameTo(new File("httpdocs/"+user.username+"ProfilePicture"+extension));
user.profilePicturePath = user.username+"ProfilePicture"+extension;
System.out.println(user.profilePicturePath);
users.put(user.username, user);
db.commit();
Does anyone know why I might be having this issue?

Create BE Initiative, BE Feature and CPM Feature using Rally Rest Client in Java

We are trying to automate the project migration from one Rally workspace to other. Everything seems to work fine like we are able to migrate project and related releases/iterations/userstories/tasks from one workspace to another workspace.
But while trying to migrate BE Initiative/BE Feature/CPM Feature we are getting some exception related to Null Pointer exception but the error we are getting in Response doesn't seem to give much info.
A sample of code is -
String oldProjectObjectId = "12345";
String newProjectObjectId = "67890";
String oldRallyWorkspaceObjectId = "32145";
String newRallyWorkspaceObjectId = "67894";
QueryResponse beInitiativeResponse = queryRally("portfolioitem/beinitiative", "/project/"+this.oldProjectObjectId, "/workspace/"+this.oldRallyWorkspaceObjectId);
int beInitiativeCount = beInitiativeResponse.getTotalResultCount();
if(beInitiativeCount >0){
JsonArray initiativeArray = beInitiativeResponse.getResults();
for(int i=0; i< initiativeArray.size();i++){
JsonObject beInitiativeObject = initiativeArray.get(i).getAsJsonObject();
String oldBeInitiativeObjectId = beInitiativeObject.get("ObjectID").getAsString();
String oldBeInitiativeName = beInitiativeObject.get("_refObjectName").getAsString();
String owner = getObjectId(beInitiativeObject, "Owner");
JsonObject BeInitiativeCreateObject = getJsonObject(oldBeInitiativeName, "/project/"+this.newProjectObjectId, "/workspace/"+this.newRallyWorkspaceObjectId, owner);
CreateResponse beInitiativeCreateResponse = createInRally("portfolioitem/beinitiative", BeInitiativeCreateObject);
if(beInitiativeCreateResponse.wasSuccessful()){
String newBeInitiativeObjectId = beInitiativeCreateResponse.getObject().get("ObjectID").getAsString();
String mapKey = oldBeInitiativeObjectId;
String mapValue= newBeInitiativeObjectId;
this.beInitiativesHashMap.put(mapKey, mapValue);
}
else{
String[] errorList;
errorList = beInitiativeCreateResponse.getErrors();
for (int j = 0; j < errorList.length; j++) {
System.out.println(errorList[j]);
}
}
}
}
queryRally and createInRally functions use Rally rest client to fetch and create the required projects and associated attributes like releases, iterations etc.
After executing CreateResponse beInitiativeCreateResponse = createInRally("portfolioitem/beinitiative", BeInitiativeCreateObject); when it's trying to execute if(beInitiativeCreateResponse.wasSuccessful()) it is instead going to else block and thus printing the below mentioned error.
An unexpected error has occurred.We have recorded this error and will begin to investigate it. In the meantime, if you would like to speak with our Support Team, please reference the information below:java.lang.NullPointerException2017-12-05 11:01 AM PST America/Los_Angeles
But the important point that is when trying to migrate projects and it's related attributes like release/iterations etc. withing same Rally workspace the above piece of code works just fine.
Update1:
While analysing the issue I made the following observations -
The workspace in which I am trying to create the BeInitiative doesn't have BEinitiative, Be Feature, CPM Feature options in Portfolio items dropdown. Rather it has Theme, Initiative and Feature options in it.
Therefore, I think I was getting the previouly mentioned error. Now I made the following changes to the code.
CreateResponse beInitiativeCreateResponse = createInRally("portfolioitem/theme", themeCreateObject);
So now instead of creating the BEInitiative I am trying to create the theme only in new workspace but getting the following error -
Requested type name \"/portfolioitem/theme\" is unknown.
The object that i am passing to CreateResponse function is -
{"Name":"xyz","Project":"/project/1804","Workspace":"/workspace/139"}
Also code for createInRally function is as mentioned below -
public CreateResponse createInRally( String query, JsonObject object) throws IOException{
CreateRequest createRequest = new CreateRequest(query, object);
CreateResponse createResponse = restApi.create(createRequest);
return createResponse;
}

The Unknown Type error was occurring as a result of not passing the workspace's object id in which we were trying to create the portfolio item.
So after modifying the createInRally function to include the workspace object id we were able to create the initiative portfolio item.
The modified createInRally function is as shown below-
CreateRequest createRequest = new CreateRequest(query, object);
createRequest.addParam("workspace", "/workspace/1333333333");
CreateResponse createResponse = restApi.create(createRequest);
return createResponse;

So this is definitely an error in the web services api. You should never get 500 responses with an unhandled nullpointer. My initial guess is that when you're creating your new object some field on it is still referencing an object in the old workspace, and when we try to correctly hook up all the associations it fails to read one of those objects in the new workspace. Can you provide some more information about what your actual object you're sending to create looks like? Specifically what object relationships are you including (that may not be valid in the new workspace)?

Update JIRA Customfield value using java

I'm simply trying to update a customfield value in jira using java. I had created a method updateCustomField which accepts 3 parameters (customFieldCode, value, jiraId). Had tried using transition but all it did is change the jira status from "Open" to "Resolved 2". I googled everywhere but they suggest to use JSON which I have no idea how to apply.
here's my update method:
public void updateCustomField(String customFieldCode, String value, String jiraId) throws Exception {
final IssueRestClient issueRestClient = jiraClient.getIssueClient();
final Issue issue = issueRestClient.getIssue(jiraId).get();
FieldInput fieldInput = new FieldInput(customFieldCode, value);
List <FieldInput> fields = new ArrayList <FieldInput> ();
fields.add(fieldInput);
TransitionInput transision = new TransitionInput(1, fields);
issueRestClient.transition(issue, transision);
}

For those who want to simply update jira using java, you can try this jira-client library.

Smack - How to read a MultiUserChat's configuration?

I tried to create a multiuserchat with Java. I'm using smack library.
Here is my code to create multiuserchat:
MultiUserChat muc = new MultiUserChat(connection, "roomname#somehost");
muc.create("mynickname");
Form form = muc.getConfigurationForm();
Form submitForm = form.createAnswerForm();
submitForm.setAnswer("muc#roomconfig_roomname", "A nice formatted Room Name");
submitForm.setAnswer("muc#roomconfig_roomdesc", "The description. It should be longer.");
muc.sendConfigurationForm(submitForm);
muc.addMessageListener(mucMessageListener); // mucMessageListener is a PacketListener
Then, I tried to capture the message sent by this room created above using mucMessageListener:
private PacketListener mucMessageListener = new PacketListener() {
public void processPacket(Packet packet) {
if (packet instanceof Message) {
Message message = (Message) packet;
// this is where I got the problem
}
}
}
As the message received by other part (the user who is not the owner of this multiuserchat), can he somehow get the value set in this line above:
submitForm.setAnswer("muc#roomconfig_roomname", "A nice formatted Room Name");
You see, getting just the JID of the room is not really good for the view. I expect I could have a String which value is "A nice formatted Room Name".
How can we get that?

You can easily get its configurations like name and etc from this code:
MultiUserChatManager mucManager = MultiUserChatManager.getInstanceFor(connection);
RoomInfo info = mucManager.getRoomInfo(room.getRoom());
now you can get its informations like this:
String mucName = info.getName();
Boolean isPersistence = info.isPersistent();
and etc.

Retrieving the value of muc#roomconfig_romname is described in XEP-45 6.4. Smack provides the MultiUserChat.getRoomInfo() method to perform the query.
RoomInfo roomInfo = MultiUserChat.getRoomInfo(connection, "roomname#somehost.com")
String roomDescription = roomInfo.getDescription()

If you want to read a value of var for example title name of room in config
Form form = chat.getConfigurationForm();
String value = form.getField("muc#roomconfig_roomname").getValues().next();
then do what ever you want with value..

Issue while adding attachment to QC Test Case using Com4j API

I am trying to add attachment to QC Test LAB Test Case run from my Java code using Com4J API. I was able to create a successful run, however while adding attachments below code is throwing invalid parameter for "IAttachment attach = attachfac.addItem(null).queryInterface(IAttachment.class);". In this case additem is expecting Java Item Object. I also tried to pass addItem(""), but then attach.Type(1) is failing with reason:- Attachment Type cannot be changed. Could anyone please help me with this:
IBaseFactory obj2 = testset.tsTestFactory().queryInterface(IBaseFactory.class);
IList tstestlist = obj2.newList("");
for(Com4jObject obj3:tstestlist){
ITSTest tstest = obj3.queryInterface(ITSTest.class);
if(tstest.name().contentEquals("[1]TC1")){
System.out.println("TC found");
IRunFactory runfactory = tstest.runFactory().queryInterface(IRunFactory.class);
IRun run=runfactory.addItem("RunNew").queryInterface(IRun.class);
run.status("Passed");
IAttachmentFactory attachfac = run.attachments().queryInterface(IAttachmentFactory.class);
IAttachment attach = attachfac.addItem("").queryInterface(IAttachment.class);
attach.type(1);
attach.fileName("Path to File TC1");
attach.post();
run.post();.
