• Java Formatter specify starting position for text

  - by purecharger

  I'm trying to position a string at a certain starting position on a line, regardless of where the previous text ended. For instance: Mandatory arguments to long options are mandatory for short options too. -a, --all do not ignore entries starting with . -A, --almost-all do not list implied . and .. The explanation of the options begin at position 30 regardless of the text preceding. How do you accomplish this with java.util.Formatter? I have tested with both the width (%30s) and precision (%.30) arguments, and neither provide the desired result.

• Java SOAP WSDL 1.1 message sending all the parameters (even future ones)

  - by Eduardo

  I have to communicate with a SOAP Web Service defined in a WSDL 1.1. All the parameters are optional in the WSDL like: <xsd:element name="Submitter" type="xsd:string"/> but if I do not send them I get an error because the parameter was not sent, so instead I have to send an empty string for any parameter I do not intent to send. So instead of not sending the element I have to send: <Submitter></Submitter> The problem is that the WebService publisher does not have any problem adding new parameters at any point in time but I must sent at least an empty string for all the parameters. How may I call this WebService in Java so every time I call the WebService the WSDL is read so that all the parameters are sent having the parameters I care for are actually filled with the data I provide? I am currently using Apache CXF but I am open to anything to solve this problem.

• Low overhead Java Web Services container?

  - by trojanfoe

  I want to provide a Java-based Web Service, but I don't require the features of a full-blown J2EE Application Server. I would like it to start as quickly as possible, though that's not a hard requirement. The Web Service will handle multiple connections and require access to an Oracle database so it will at least require a thread pool and database connection pool. I may want to put a JSP interface onto it later to provide an internal maintainence interface. I have looked at Jetty with an Apache CXF stack, but it looks like I'll have to do a fair amount configuration before even coding the web service - Will it be worth it? Will it even work? Should I forget about the complexity and simply go with JBoss/Weblogic/etc and put up with the bloat and extra start-up time?

• A good Sorted List for Java

  - by Phuong Nguyen de ManCity fan

  I'm looking for a good sorted list for java. Googling around give me some hints about using TreeSet/TreeMap. But these components is lack of one thing: random access to an element in the set. For example, I want to access nth element in the sorted set, but with TreeSet, I must iterate over other n-1 elements before I can get there. It would be a waste since I would have upto several thousands elements in my Set. Basically, I'm looking for some thing similar to a sorted list in .NET, with ability to add element fast, remove element fast, and have random access to any element in the list. Has this kind of sorted list implemented somewhere? Thanks.

• How to implement image map type interface for a game board in Java 6

  - by Billy

  My group project at school is to implement a style of monopoly in which students can buy courses and land on various squares and move around the board. This is not a regular square board so we were wondering if anyone had any ideas on how we would implement an image map or something like it to create many clickable regions not in a perfect square. I have attached the image of the game board. Just a way to start is needed, not lots of code or anything as we all know java pretty well. If anyone has any ideas that would be great. Image of board is here. http://imgur.com/fH5WC.png

• MySQL with Java: Open connection only if possible

  - by emempe

  I'm running a database-heavy Java application on a cluster, using Connector/J 5.1.14. Therefore, I have up to 150 concurrent tasks accessing the same MySQL database. I get the following error: Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Too many connections This happens because the server can't handle so many connections. I can't change anything on the database server. So my question is: Can I check if a connection is possible BEFORE I actually connect to the database? Something like this (pseudo code): check database for open connection slots if (slot is free) { Connection cn = DriverManager.getConnection(url, username, password); } else { wait ... } Cheers

• Doubt about constructor in JAVA

  - by Harry Joy

  I have few doubts regarding constructor in java Can a constructor be private? If yes then in which condition? Constructor is a method or not? If constructor does not return anything then why we are getting a new Object every time we call it. Whats the default access modifier of a constructor if we did not specify. Thanks & Regards Edit---------- Answer for 1 & 3 are very clear. But still doubt about 2&4 as i'm getting different answers for them.

• Can Somebody Explain this java code

  - by dubbeat

  Hi, I'm just starting out on android and my java is verry rusty. I can't remember ever seeing a function nested in another function like this before. Could somebody explain to me exactly what final does and explain why you would nest a function in another like this? private final Handler handler = new Handler() { @Override public void handleMessage(final Message msg) { Log.v(Constants.LOGTAG, " " + ReviewList.CLASSTAG + " worker thread done, setup ReviewAdapter"); progressDialog.dismiss(); if ((reviews == null) || (reviews.size() == 0)) { empty.setText("No Data"); } else { reviewAdapter = new ReviewAdapter(ReviewList.this, reviews); setListAdapter(reviewAdapter); } } };

• Disambiguating Named Entities in Java

  - by Alterscape

  I have a list of strings (company names, in this case), and a Java program that extracts a list of things that look like company names out of mostly-unstructured text. I need to match each element of extracted text to a string in the list. Caveat: the unstructured text has typos, things like "Blah, Inc." referred to as "Blah," etc. I've tried Levenshtein Edit Distance, but that fails for predictable reasons. Are there known best-practices ways of tackling this problem? Or am I back to manual data-entry?

• Java - converting String in array to double

  - by cc0

  I'm stuck with this pretty silly thing; I got a textfile like this; Hello::140.0::Bye I split it into a string array using; LS = line.split("::"); Then I try to convert the array values containing the number to a double, like this; Double number = Double.parseDouble(LS[1]); But I get the following error message; Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1 Does anyone have any idea why this doesn't work?

• download mail attachment with Java

  - by Don

  Hi, I had a look in the reference doc, and Spring seems to have pretty good support for sending mail. However, I need to login to a mail account, read the messages, and download any attachments. Is downloading mail attachments supported by the Spring mail API? I know you can do this with the Java Mail API, but in the past I've found that very verbose and unpleasant to work with. EDIT: I've received several replies pointing towards tutorials that describe how to send mail with attachments, but what I'm asking about is how to read attachments from received mail. Cheers, Don

• Connecting a PHP front-end to a back-end java service

  - by christopher-mccann

  I am currently using various back-end services and I want to use PHP to simply query these services and perform the final page construction. These services could be coded in any number of programming langauges such as Erlang, Java, Python etc. However I am unsure of the best way to actually interface the back-end services with the web app. Requests to these services would be both synchronous and asynchronous. Would I use something like SOAP or JSON-RPC?? Any help greatly appreciated.

• Issued by DNOA service access token parsing and validating in Java application

  I am creating OAuth 2.0 access token using DotNetOpenAuth, like here public AccessTokenResult CreateAccessToken( IAccessTokenRequest accessTokenRequestMessage) { var token = new AuthorizationServerAccessToken(); token.Lifetime = TimeSpan.FromMinutes(10); var signCert = LoadCert(Config.STS_CERT); token.AccessTokenSigningKey = (RSACryptoServiceProvider) signCert.PrivateKey; var encryptCert = LoadCert(Config.SERVICE_CERT); token.ResourceServerEncryptionKey = (RSACryptoServiceProvider) encryptCert.PublicKey.Key; var result = new AccessTokenResult(token); return result; } Token issued by this method looks like: { "access_token": "gAAAAH44atDAyWeu8BFwhLof7rtBRpiZrSlAC0zci8xU81tXHZDVkBX8LXrMLDHDYfimjuSOsdrXQIAY7Xf4JnK1x_fo_JSmvuiA5CvO5JUJNuEmHNSlR4ePO4tBPkOHQnN50DIRJMbHJdQrFZCqqaWz6s0iuvCuTMcTua6J0yaTPQaD9AAAAIAAAADHgef78SHh4-K2aZ87xYRoRFfmQ0lc3ET7Y5vAS7BadLM5btYvmrSkAWsCxhUji92D0LbKgyVkbQuuw5LnRP_zsxe_W_VztTqZ5m9PwJDL6q7McrUfiVQj_XBQqpv2slBeouD0F1k1KjVedR9Pwm7ganz4R7dmeYivnx8f0_isEGBqSZrtnILoit3SOCPyVxmIwizYwLE2bQOtlwVpqtrBMyzc4MVPVyaSiJb2-Lj5tOftEWl0k93Qmr8uzmjDyeCn3TsFX0f_qFgCmxp32_kt4ZTMf4zgmh5yUS1Hy7ERNQxpCIxRTx9yma7JN_K5Pss", "token_type": "bearer", "expires_in": 43200, } I need to know whether Java application will be able to parse and validate token issued in such manner?

• Help with setting up panels in Java

  - by Milos

  I'm new to Java awt, so I am having trouble with setting up panels. I have one giant panel, which needs to hold 3 panels inside (photo is attached at the bottom). One will go on top(1), second one will be in the middle(3), and third goes on the bottom(2). Any remaining space has to be divided equally between (1)/(3) and (3)/(2). Also, the middle panel (3) is a table, so GridLayout has to be used. How can I achieve this? Thanks in advance! P.S. I've tried to draw it in MS Paint (http://i45.tinypic.com/2w523ie.jpg)

• Java, how to trace functions called

  - by user435657

  Hi all, I want to trace the beginning [& ending] of functions called in Java, like the following code: public void foo() { System.out.println("begin of foo()"); ... System.out.println("e-n-d of foo()"); } But maintaining of the dump code System.out.println is something tedious and error-prone, for there may be tens of thounds of function in an class. Any good idea can ease this work? I don't want dump statements all over the file. Implementation of both or one of the beginning & ending traces is perferd. But, if impossible, recordings of that the function has been called is also helpful. I mean not care the exact beginnig and ending, just tell that the function has been called.

• Java Security filter together with thickbox pop-ups

  - by user197127

  Hi, I have a java application that uses a security filter to protect certain resources. If there is no user logged on, it will keep in session the request path and redirect to a logon page. After a successful logon, user is redirected to the original requested page. I have now added some thickbox (ajax bases pop-up) popups to the application. Unfortunately, when I get now a popup that is "secure" the filter redirects to a logon page (which is not a popup) and makes the whole application messy. Anyone with ideas on how to solve this? Thanks

• Loading a Windows DLL in Java and initiate a class from it

  - by Joy

  I have a Windows DLL file from .NET namely "System.Management.dll". I work with it using the code I write below: ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_LogicalDisk WHERE Name = 'C:'"); foreach (ManagementObject queryObj in searcher.Get()) { Console.WriteLine("Win32_LogicalDisk instance: "); if (queryObj["VolumeSerialNumber"] != null) { Console.WriteLine("Drive Name : " + queryObj["Name"]); Console.WriteLine("VolumeSerialNumber:", queryObj["VolumeSerialNumber"]); SysdriveSerial = queryObj["VolumeSerialNumber"].ToString(); } } Now I need this piece of code to be in Java. So can I do this? Without anything like c++ unmanaged code. I don't want to use c++ unmanaged code to call to this dll. I want something like this : public class CallToCsharp { private static native void ManagementObjectSearcher(); public static void main(String[] args) { System.loadLibrary("System.Management"); System.out.println("Loaded"); ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_LogicalDisk WHERE Name = 'C:'"); } }

• Understanding character encoding in typical Java web app

  - by Marcus

  Some pseudocode from a typical web app: String a = "A bunch of text"; //UTF-16 saveTextInDb(a); //Write to Oracle VARCHAR(15) column String b = readTextFromDb(); //UTF-16 out.write(b); //Write to http response In the first line we create a Java String which uses UTF-16. When you save to Oracle VARCHAR(15) does Oracle also store this as UTF-16? Does the length of an Oracle VARCHAR refer to number of Unicode characters (and not number of bytes)? And then when we write b to the ServletResponse is this being written as UTF-16 or are we by default converting to another encoding like UTF-8?

• Nested CheckBox in Java

  - by Shailesh Ahuja

  I want to create a nested checkbox list. If the user checks the main item, all the sub-items under and get checked. If the user checks some of the sub-items, then a blue square appears inside the main items checkbox. It should look something like this. How do I do that in Java 1.6? Can I use swing or any external library? I would like to choose the easiest and the fastest way to achieve this? My aim is to create only 1 level of nesting.

• Inheritance in XML Schema definition (XSD) for Java objects

  - by bguiz

  Hi, I need to create an XML schema definition (XSD) that describes Java objects. I was wondering how to do this when the objects in question inherit from a common base class with a type parameter. public abstract class Rule<T> { ... } public abstract class TimeRule extends Rule<XTime> { ... } public abstract class LocationRule extends Rule<Location> { ... } public abstract class IntRule extends Rule<Integer> { ... } .... (where XTime and Location are custom classes define elsewhere) How would I go about constructing an XSD that such that I can have XML nodes that represent each of the subclasses of Rule<T> - without the XSD for each of them repeating their common contents? Thank you!

• Create a Visual Studio type look using Java Swing

  - by JeffHeaton

  I would like to create extend a Java Swing application to have a look somewhat similar to an IDE such as Eclipse or Visual Studio. That’s, there would be a panel at the left that displays a tree, and a tab panel on the right that allows several elements of the tree to be opened and edited on right. For this I could easily use a BorderLayout and just use the center and left areas. However, I would also like to have the ability for the user to drag the border between these two panels, just like Eclipse and Visual Studio allow. I can think of several ways to do this, but was curious if anyone had found a particularly good way to do this, or knew of an example. I’ve googled for it, but have not found anything.

• Inconsistency in java.util.concurrent.Future?

  - by loganj

  For the sake of argument, let's say I'm implementing Future for a task which is not cancelable. The Java 6 API doc says: After [cancel()] returns, subsequent calls to isDone() will always return true. [cancel()] returns false if the task could not be cancelled, typically because it has already completed normally It also says: [isDone()] returns true if this task completed. But what if my cancellation fails not because the task is already completed, but because it simply cannot be cancelled? Is there a way out of this contradiction (other than making my uncancelable task cancelable and sidestepping it altogether)?

• Java application if/case recommendation

  - by Jesse

  I am writing an application for a Java course. I am a complete beginner and am just going off material I have learned from the course and from the web. The application is exhibiting some behavior and I am not sure what is causing it. The application is GUI based and does calculations on user input. For the action listener section, I have a set of If statements such as: "if this button do this if this button do this" All in a row like that. It seems as if the application is running ALL the if statements instead of running the one that corresponds with the button pressed. Would I be better off using a case/switch structure for this sort of thing? I can post my code if necessary, I am new around this site and am not sure if that thing is acceptable.

• Check if a class is subclass of another class in Java

  - by craesh

  Hi! I'm playing around with Java's reflection API and trying to handle some fields. Now I'm stuck with identifying the type of my fields. Strings are easy, just do myField.getType().equals(String.class). The same applies for other non-derived classes. But how do I check derived classes? E.g. LinkedList as subclass of List. I can't find any isSubclassOf(...) or extends(...) method. Do I need to walk through all getSuperClass() and find my supeclass by my own? Thanks! craesh
