  • TreeMap randomly stops properly returning values

    - by smessing
    I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else ever encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

  • Why does multiplying a double by -1 not give the negative of the current answer

    - by Ankur
    I am trying to multiply a double value by -1 to get the negative value. It continues to give me a positive value double man = Double.parseDouble(mantissa); double exp; if(sign.equals("plus")){ exp = Double.parseDouble(exponent); } else { exp = Double.parseDouble(exponent); exp = exp*-1; } System.out.println(man+" - "+sign+" - "+exp); The printed result is 13.93 - minus - 2.0 which is correct except that 2.0 should be -2.0

  • Tomcat Compression Does Not Add a Content-Encoding: gzip in the Header

    - by Julien Chastang
    I am using Tomcat to compress my HTML content like this: <Connector port="8080" maxHttpHeaderSize="8192" maxProcessors="150" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="150" connectionTimeout="20000" disableUploadTimeout="true" compression="on" compressionMinSize="128" noCompressionUserAgents="gozilla, traviata" compressableMimeType="text/html" URIEncoding="UTF-8" /> In the HTTP header (as observed via YSlow), however, I am not seeing Content-Encoding: gzip resulting in a poor YSlow score.

    Hi all, I'm new to JTable.I'm working in Swings using JTable & Toplink(JPA). I have two buttons "add Row", "Del Row" and I have some records displayed from db. when ever "add row" is clicked a new record, row header should be added to JTable with an auto increment number displayed in sequential order to the JTable Row Header. During deletion using "Del row " button the record has to be deleted & not its corresponding header so that next rows got updated to the previous headers & the auto increment number remain unchanged and always be in sequence. please help me on this regard.

  • Creating method templates in Eclipse

    - by stevebot
    Is there any way to do the following in eclipse? Have eclipse template a method like the following public void test(){ // CREATE MOCKS // CREATE EXPECTATIONS // REPLAY MOCKS // VERIFY MOCKS } so then I could presumably just use intellisense and select an option like "createtest" and have it stub out a method with the comments similar to the above?My problem is that often myself and other developers I know forgot all the steps we need to follow to do what we dub as a valid unit test for our application. If I could template our test methods to stub out the comments above it would be a big help.

  • Invoke webservice using jaxws when the wsdl has more than one service

    - by Hugo Palma
    I'm trying to get hold of the FindService on this wsdl using jaxws. I generated the classes just fine using wsimport. But when i do: FindService findService = new FindService(); i get the exception: Exception in thread "main" javax.xml.ws.WebServiceException: {http://s.mappoint.net/mappoint-30/}FindService is not a valid service. Valid services are: {http://s.mappoint.net/mappoint-30/}CommonService So, it seems that jaxws is only finding CommonService in the wsdl which is the first one declared in it. Any idea how i can use the FindService ? Thanks.

  • JPA optimistic lock - setting @Version to entity class cause query to include VERSION as column

    - by masato-san
    I'm using JPA Toplink Essential, Netbean6.8, GlassFish v3 In my Entity class I added @Version annotation to enable optimistic locking at transaction commit however after I added the annotation, my query started including VERSION as column thus throwing SQL exception. None of this is mentioned in any tutorial I've seen so far. What could be wrong? Snippet public class MasatosanTest2 implements Serializable { private static final long serialVersionUID = 1L; @Id @Basic(optional = false) @Column(name = "id") private Integer id; @Column(name = "username") private String username; @Column(name = "note") private String note; //here adding Version @Version int version; query used: SELECT m FROM MasatosanTest2 m Internal Exception: com.microsoft.sqlserver.jdbc.SQLServerException Call: SELECT id, username, note, VERSION FROM MasatosanTest2

  • How do you document anonymous functions ?

    - by clutch
    I'm specifically referring to JavaScript anonymous function but this could be relevant to other languages. I like to use JSDoc notations in my scripts because I know other people will be hacking at it sooner or later. When i have pretty complex anonymous function how do people document it so that it gets picked up by Eclipse and other IDE's that understand JSDoc or JavaDoc notations? /** * Blah Blah blah * * @param Object Blah blah blah * @return Blah Blah Blah * @type Object */ function foo(this) { ...... this.bar = function () { ... complex code .....}; ...... return obj; } Thanks

  • Android spinner inside a custom control - OnItemSelectedListener does not trigger

    - by Idan
    I am writing a custom control that extends LinearLayout. Inside that control I am using a spinner to let the user select an item from a list. The problem I have is that the OnItemSelectedListener event does not fire. When moving the same code to an Activity/Fragment all is working just fine. I have followed some answers that was given to others asking about the same issue, and nothing helped. still the event does not fire. This is my code after I followed the answers that suggested to put the spinner inside my layout XML instead of by code. I am getting the same result when I try to just "new Spinner(ctx)"... layout XML: <Spinner android:id="@+id/accSpinner" android:layout_width="0dip" android:layout_height="0dip" /> Initialization function of the control (called on the control constructor): private void init() { LayoutInflater layoutInflater = LayoutInflater.from(mContext); mAccountBoxView = layoutInflater.inflate(R.layout.control_accountselector, null); mTxtAccount = (TextView)mAccountBoxView.findViewById(R.id.txtAccount); mSpinner = (Spinner)mAccountBoxView.findViewById(R.id.accSpinner); mAccountBoxView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { mSpinner.performClick(); } }); setSpinner(); addView(mAccountBoxView); } private void setSpinner() { ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_spinner_item, mItems); dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); mSpinner.setAdapter(dataAdapter); mSpinner.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { String selectedItem = mItems.get(position); handleSelectedItem(selectedItem); } @Override public void onNothingSelected(AdapterView<?> parent) { } }); } The spinner raises just fine when i touch my control and the list of items is there as it should. When I click an item the spinner closes but I am never getting to onItemSelected nor onNothingSelected.. Any ideas?

  • rich suggestions - why input is null? (seam framework)

    - by Cristian Boariu
    Hi, I'm trying to build a rich suggestions and i do not understand WHY the input value is null... I mean, why inputText value is not taken when i enter something. The .xhtml code: <h:inputText value="#{suggestion.input}" id="text"> </h:inputText> <rich:suggestionbox id="suggestionBoxId" for="text" tokens=",[]" suggestionAction="#{suggestion.getSimilarSpacePaths()}" var="result" fetchValue="#{result.path}" first="0" minChars="2" nothingLabel="No similar space paths found" columnClasses="center" > <h:column> <h:outputText value="#{result.path}" style="font-style:italic"/> </h:column> </rich:suggestionbox> and action class: @Name("suggestion") @Scope(ScopeType.CONVERSATION) public class Suggestion { @In protected EntityManager entityManager; private String input; public String getInput() { return input; } public void setInput(final String input) { this.input = input; } public List<Space> getSimilarSpacePaths() { List<Space> suggestionsList = new ArrayList<Space>(); if (!StringUtils.isEmpty(input) && !input.equals("/")) { final Query query = entityManager.createNamedQuery("SpaceByPathLike"); query.setParameter("path", input + '%'); suggestionsList = (List<Space>) query.getResultList(); } return suggestionsList; } } So, input beeing null, suggestionList is always empty... Why input's value is not posted?

  • How to tell axis2 to use an existing object as a service?

    - by Christian Hausknecht
    I am trying to expose some methods of a running application as a webservice. The core idea is to use an embedded web-server and send the soap messages to the apache axis2 framework in order to invoke the services. The problem is, that axis2's createService methods only accept Classes as parameter, not existing objects. So I believe that axis2 itself creates an object of the service class and then uses it to call methods when an external service call arrives. But I need to pass an existing object for being used as a service, because I need to call methods of other objects of the running application within the service methods. So the "standard" way that axis2 creates a new instance of the service class and calls then its methods is obviously no sulution for me. So is there a way to realize this? Or is there another solution? Perhaps you can pass objects later on to the allready created service object by axis2? If there is another solution without axis2 I might consider that one. Basically I am only interested in exposing some functionality of a runnning application as a webservice.

  • Hibernate sequence should only generate when ID is <=0

    - by Tim Leys
    Hi all, I'm using the folowing sequence in my code. (I got the sequence and @Id @SequenceGenerator(name = "S912_PRO_SEQ", sequenceName = "S912_PRO_SEQ", allocationSize = 1) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S912_PRO_SEQ") @Column(name = "PRO_ID", unique = true, nullable = false, precision = 9, scale = 0) public int getId() { return this.id; } And using the following sequence / triggers in my DB. CREATE SEQUENCE S912_PRO_SEQ nomaxvalue minvalue 20; CREATE OR REPLACE TRIGGER S912_PRO_B_I_TRG BEFORE INSERT ON S912_project REFERENCING OLD AS OLD NEW AS NEW FOR EACH ROW ENABLE begin IF :NEW.pro_ID IS NULL THEN select S912_PRO_SEQ.nextval into :new.pro_ID from dual; END IF; end; I was wondering if there is a way to let hibernate generate a sequence ONLY if the ID is <=0 (not set) or if the ID already exists. I know for most cases my trigger would fix the situation. But I do not want to rely completely on it. I hope someone can help me out :p

  • Include static file in JSP with variable filename on WebSphere 6

    - by cringe
    I'm struggling with including a static file into my JSPs on Websphere 6.0.2.17. I tried this: <% final String MY_DIR = ResourceBundle.getBundle("mybundle").getString("props.pages.wcm"); %> <% final String page = ResourceBundle.getBundle("mybundle").getString("page"); %> <% final String inc = MY_DIR + "/" + bonus; %> <%@include file="<%= inc %>"%> The path is /wcm/some/other/dir/page and I can happily print that out with out.write(inc). Unfortunatly the include (and the jsp:include) isn't including the file at all. There is no error message, but the content isn't included... The file is accessible via the browser though. Do I have to create a full JSP for this to work? I just need a HTML file.
