This tab contains all the opinions collected from Stack Overflow about the API. The other tabs present summaries of the opinions using different algorithms.
  • Do you also want all the "inherited" properties that comes with java.util.Properties, like java.home ?. details
  • It's working just fine.. details
  • I worked, thanks.. details
  • Thanks!. details
  • Show the code of your Registration class, please.. details
  • I got the json content as a result from a GET request using google custom search API.. just extra information in case it can help in some ways!. details
  • Thanks!.. details
  • You are absolutely right!. details
  • OH!. details
  • JSONObject is a java.util.Map and JSONArray is a java.util.List, so you can access them with standard operations of Map or List .. details
  • JSONObject is a java.util.Map and JSONArray is a java.util.List, so you can access them with standard operations of Map or List .. details
  • I've continued the properties file approach and it has greatly reduced maintenance effort each time something needs to be added and changed, but still doesn't quite feel seamless.. details
  • CODETERM3 is a java.util.Date (MySQL -> date) and I annotated the POJO like this: CODESNIPPET_JAVA3 .. details
  • Removing CODETERM6 , everything is okay and works as expected.. details
  • Thank you for your question.. details
  • Most of what I have done has been smooth as butter but for some reason I am having issues converting JSON timestamp strings into CODETERM1 objects.. details
  • Most of what I have done has been smooth as butter but for some reason I am having issues converting JSON timestamp strings into CODETERM1 objects.. details
  • The JSON that is coming in looks like this.. details
  • You can use the return value from URL_http://docs.oracle.com/javase/6/docs/api/java/util/Set.html#add%28E%29 [CODETERM6] , which true if the set did not already contain the specified element, to check that the word being added is in fact unique: CODESNIPPET_JAVA3 .. details

  • "result" as String works fine but for the "registration_moment" I get this exception:java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to Registration I also tried casting it to a String in the same way as "result" and doing mapper.readValue on that string.No success.. details
  • Please tell me in an easy way because I am a beginner (just touched NetBeans for 2 months).. details
  • Many thanks!!!. details
  • Any input will be appreciated.. details
  • BTW, the fact that you require this, doesn't sound correct.. details
  • Once you have guessed some good "business objects" built in your configuration you can reduce the configuration to an array of those objects.. details
  • Also, the json solution may be good, since structuring your properties in a hierarchical tree may help to keep down the complexity in your configuration files, but again I would avoid mapping the json object to a Java object since your model is subject to change frequently (as far as I understand).. details
  • So you need two things in my opinion: 1. extract some organization in your configuration 2. use some structured configuration format (like JSON or XML) .. details
  • Any help would be appreciated.Thanks,Eric Now I just have to fix my javascript to treat the groups array as an array and not a string: CODESNIPPET_JAVA5 .. details
  • @Ted Hopp: Thanks for creating/adding the svenson tag.. details
  • Well, you could use List.indexOf(), as others have suggested: URL_http://docs.oracle.com/javase/6/docs/api/java/util/List.html#indexOf%28jav a.lang.Object%29 [Java-List-API:-indexOf()] If you plan on doing this a lot, then presumably you have a handle on your Object reference.. details

  • Thanks a lot.. details
  • OK, I am probably being slow, but what would that look like then ?. details
  • If this is not the case, you could convert to a java.util.List as well.. details
  • So you're JSON could look something like: CODESNIPPET_JAVA1 .. details
  • The following represent valid three-dimensional matrices which should be perfectly handled by Gson: CODETERM4 (recommended) CODETERM5 CODETERM6 CODETERM7 CODETERM8 That said, I would prefer URL_http://download.oracle.com/javase/6/docs/api/java/util/List.html [CODETERM9] above URL_http://download.oracle.com/javase/6/docs/api/java/util/Collection.html [CODETERM10] in this particular case.. details

  • The JSON that is coming in looks like this .
  • Any help would be appreciated Thanks,Eric Now I just have to fix my javascript to treat the groups array as an array and not a string: CODESNIPPET JAVA5 .
  • If this is not the case, you could convert to a java util List as well .

  • JSONObject is a java util Map and JSONArray is a java util List, so you can access them with standard operations of Map or List .

  • Also, the json solution may be good, since structuring your properties in a hierarchical tree may help to keep down the complexity in your configuration files, but again I would avoid mapping the json object to a Java object since your model is subject to change frequently (as far as I understand) .
  • Well, you could use List indexOf(), as others have suggested: a lang Object%29 Java List API: indexOf() If you plan on doing this a lot, then presumably you have a handle on your Object reference .

      • To be honest I do not see how this works with even known types.. details
      • If you're doing anything _significant_ with dates and times, I'd thoroughly recommend using URL_http://joda-time.sf.net [Joda-Time] instead of the classes in java.util.. details
      • Code for my collection based on java.util.list looks more or less like this: CODESNIPPET_JAVA2 .. details

      • Most of what I have done has been smooth as butter but for some reason I am having issues converting JSON timestamp strings into CODETERM1 objects.. details
      • Also, the json solution may be good, since structuring your properties in a hierarchical tree may help to keep down the complexity in your configuration files, but again I would avoid mapping the json object to a Java object since your model is subject to change frequently (as far as I understand).. details
      • So you need two things in my opinion: 1. extract some organization in your configuration 2. use some structured configuration format (like JSON or XML) .. details
      • So I don't think I need to create a new class as the JSON will be very simple like: {"pref1", "pref2"...}, so I was trying to get it added to a List (@RequestBody List body), but this doesn't seem to be getting the following error message, "Can not deserialize instance of java.util.List out of START_OBJECT token".. details
