I tried to visit my webapp with /appinfo appended after the context url but I get a 404 and I see no errors in the GlassFish4 log.
My project is using JSF 2.x with the viewservlet mapped on *.xhtml and it is using Spring Beans as well (using the Spring Context Loader), mapped to /rest/*. Do I need to map something else?
I can only get this servlet working without annotations but only using the old web.xml way.
I don't know what I need to do to get my servlet working with annotations.
I was just programming, when I discovered that you can create custom annotations. So I was wondering: what can I use these for? I a m also curious about what the limitations and possibilities are and what to put in the program.
I have a bean that represents data been collected from a form on a jsp page. Currently I would like to validate my fields and write some test cases for them. As you can see from my test case example I test a string in the hope that it fails because it contains only one letter. My problem is my unit test is passing. The reason this is from what I can tell is that at runtime it fails when I try to persist my object using my entity manager. During my unit test I just I don’t call my entity manager I just try and set the field.
What I thought would happen was that when I use my bean fields set method the annotations would be checked and fail at that point. Hence why I expected my unit test in this case to fail.
What I would like to know is
1.Are annotations specifically designed to validate when I persist my object and am I using them incorrectly at this point?
2.Is this the best method to use to validate fields, is there a better way, should I write my own code to validate for me when I set my value?
a. Should I throw an exception from the set method of each bean field?
Unit Test:
@Test public void testName(){ Human h=new Human(); try { h.setFname("a"); } catch (Exception e) { // TODO Auto-generated catch block fail("failed"); e.printStackTrace();
I have imported several maven projects but I am trying to import a spring project via eclipse and it is not displaying. I did the following file->import->Existing maven projects->browse (found my project)->finish..... The project does not display and I cannot find it. I tired to do it again and the project cannot import because I cannot select it meaning it is already installed.
public class StudentJDBCTemplate implements StudentDao
above class giving error as
The type StudentJDBCTemplate must implement the inherited abstract method
StudentDao.listStudents()
Interface is as below

In my integration test, I tried to use resttemplate to send a Get request to a dummy server created by MockMvcBuilders. However I got an error:I/O error on GET request for `"http://localhost:8080/test"`:Connection refused:(In the function testAccess(), url is `"http://localhost:8080/test"`). My code is as below:
@RunWith(SpringJUnit4ClassRunner.class) @WebAppConfiguration @IntegrationTest("server.port=8080") public class MyTest { private MockMvc mockMvc = null;
My requirement is to display a table containing multiple rows and multiple columns. and row headers must be link type and that table should be retrieved dynamically from db where the values entered by the admin. this is the user view. and am new to spring. unable to implement this. my demo is on monday and i need to show the demo to survive in this job. I had given the link. but am unable to implement by seeing that also because it has no complete code which is my actual requirement. Code should be written in controllers, pojo, dao's, jsp's etc... URL....
In my code am unable to get in one table. So I went with alternative that to come each row and 3 columns in one table... 4 rows 4 different tables I did... but it was not my requirement. I used embedded to get that...in my pojo I wrote
and each embedded one i have created 4 pojo's where i wrote column headers. get it all in one table view with 4 row headers and 3 column headers but this is not my requirement...
For some time i've been trying to rewrite my XML configurated webapp into one that has Java Based cofiguration. Unfortunately ,even after going through many tutorials i've been unable to do so.
currently we can able to monitor all calls given to this class but whenever any exception thrown in this class hierarchy we are not able to track it on exceptions.jsp of JAMON
URL....In the mentioned project in this blog I used Spring Web Flow to satisfy some requirements but now that development of the Spring Web Flow stopped I like to check what Faces Flows can present to satisfy the same requirements.From a quick look similarities between Spring Web Flow and Faces Flows are obvious but there is one specific point I like to ask.In SWF it is possible to define flowing element at the beginning of an flow.
which will trigger an event when you will start executing a flow, I look to the Faces Flows flow descriptors but I can see an element that fullify similar requirement.similar functionality built into the Faces Flow or not?And is there a way to configure Faces Flows that it reacts to events from the users like the following.
I am trying to find a way to make a URL that is used during a background AJAX call to log a user out more flexible. Currently, I have it as a static value, as below:
var logoutURLTest = "https://test.myorg.com/cas/logout"; ...AJAX stuff that uses the logoutURLTtest variable...
However, if that URL was to change for any reason, I would have to modify one or more JSPs if they were affected, instead of just changing it at a single point in the Spring environment context. It would be more desirable to expose the value using a property placeholder; however, the Spring documentation isn't exactly clear on whether this is possible.
in my ui i will i will select enabled or disabled then it will go in controller , i already debug it and it goes on the right controller based on what i select on ui my problem is when i select disabled it dont display the message but when i select enabled it displays the message, then i check the databases status is change based on what i select but when i change into disabled doesnt display any message.if select enabled will go in controller then change status into true then update the status then will see the message in ui
When I hit the url at the first time my call goes to the spring controller and sets the userDetails objects in the modelAndView.addObject("userDetails", userDetails.getUserDetails()) and returns the userDetails.html page. if I click any link in the same page i want to pass same (userDetails) object thru javascript or jquery and calls the another(controller) method and returns the same (userDetails.html) page.
It means how can I pass the java object thru javascript or jquery and calls the controller. If I get the same object in my controller i can avoid calling the db again.
I am going to develop a new web application of medium complexity. Right now i am somewhat comfortable with JSF and hibernate. I have never used JSF and hibernate together before.I just wanted to ask if it is good practice to use JSF (for both view layer and handling business logic) and hibernate(for persistence) without spring as a middle layer. The reason why i am asking this is i don't know anything about spring framework.
There is a weblogic server running at remote place and i need to access the API's in that remote method using JNDI lookup. My application is configured in Spring Tool Suite IDE with java 6 and tomcat 7 and I have used Spring to perform the jndi lookup of weblogic server. In spring i have used simpleremotestatelesssessionproxyfactorybean class to lookup a weblogic server using jndi and get the remote object. But somehow on doing it i'm getting the following error.
org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 203 completed: Maybe at com.sun.corba.se.impl.logging.ORBUtilSystemException.writeErrorSend(Unknown Source) at com.sun.corba.se.impl.logging.ORBUtilSystemException.writeErrorSend(Unknown Source) at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.sendWithoutLock(Unknown Source) at com.sun.corba.se.impl.encoding.BufferManagerWriteStream.sendFragment(Unknown Source)
[Code] ....
The exception is been thrown at com.sun.corba.se.impl.encoding.CDROutputObject method when calling writeTo(). Why I'm getting this error and can I do anything to remediate it. Irrespective of java this error occurs, i tried with java 5, 6 and 7 but still getting the same error.
I am working on a project that uses a custom tag in a JSP file. Here is the tag descriptor
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd"> <taglib> <tlibversion>1.0.0</tlibversion> <jspversion>1.1</jspversion>
[code]...
Everything seems working fine except that the custom tag handler does not get called at call. I set breakpoint and it never stops there. The JSP page is displayed fine, only not showing the custom tag content and there is no logged error/warning from the log. The tld is found fine. Like what classes called/validated the tag handler so I can logging those classes at DEBUG level to see what goes wrong.
I would like to create a custom tag which works similar to <c:forEach/> tag i.e
<c:forEach var = "movie" items = "${collection}> ${movie} </c:forEach>
I would want to create the similar behaviour(as above) in my own custom Tag.Morever I would like to use the doStartTag() and doEndTag() and doAfterBody() methods while creating custom Tag.
My jsp page needs to have a dropdown box. on selecting one/more than one values from this list, the same values get populated in another one.. we have a delete button too , it allows to populate the second box again.
The thing is i am to avoid scripts and use custom tags as much as i can...
I am supposed to implement a custom Map interface and I'm having some trouble with this method:
// 1. From the interface /** * Gives an iterator iterating over the key set from the smallest key that is not less than the key provided. * @param key the key * @return the iterator * @throws NullPointerException if key == null */
public Iterator<Key> tailIterator(Key key);
[Code] .....
My implementation is wrong according to a JUnit test. Also, to get a full score this method should have a worst case running time of O(log N), which obviously isn't the case now. (My Map implementation is currently based on binary search in an ordered array, keeping a prallel array for the values).
I'm having trouble creating a highly efficient algorithm for counting within a custom scale. This problem applies to futures trading, specifically treasuries contracts.
One specific treasury contract has 32 units before rolling over to the next whole number. So, the price scale looks something like this ...
If I pick a number (price) at random, let's say 1 28, and I want to add 8 units to that value, I should end up with 2 4. I can do this using brute force, calculating remainders, etc, etc....

I cant custom my own icon. There is no error. But the image that I tried to show in the joptionpane is not showing. What should i do?
I have a java code that should sort an array of names based on the last name. e.g jane a, jane b, jane z, jane d should be jane a, jane b, jane d, jane z. I have the following code but for some reasons, the s1 in the comparator method is always null.
public class ShuffleName { public static void sortNames(String[] names){ Arrays.sort( names, new Comparator<String>() { public int compare( String s1, String s2 ) { String s1last = s1.split("s+")[1]; String s2last = s2.split("s+")[1]; return s1last.compareTo(s2last);
