• SOCharts: Charts by Tags

  - by abhin4v

  Screenshot I created this small app as a weekend hack. It shows the reputations, upvotes, downvotes and accepted answers for a user against the tags for the answers. About I wanted to know how may upvotes I was away from getting the bronze badge for the clojure tag. But I could not find any straightforward way of doing that. So I wrote this app (in Clojure, of course). The SO API is used for the data and the charts are created using the Google Chart API. The charts are opened in the default browser. License Licensed under EPL 1.0. Download If you have Clojure and Leiningen installed, you can simply get the code from https://gist.github.com/725331, save it as socharts.clj and then run lein repl -e "(load \"socharts\")(refer 'socharts.socharts)(-main)" for launching the Swing UI If you don't have Clojure installed, but have Java then download the standalone jar from http://dl.dropbox.com/u/5247/socharts-1.0.0-standalone.jar and run it as javaw -jar socharts-1.0.0-standalone.jar Once the UI is launched, just type your user id in the input box and press <ENTER>. It will take some time to download the data from the SO API (the progress bar shows the download progress) and then it will open the charts in your default browser. You can also run it as a command line app by running lein repl -e "(load \"socharts\")(refer 'socharts.socharts)(-main <userid>)" or java -jar socharts-1.0.0-standalone.jar <userid> where you replace <userid> with your user id. Be warned that because of a missing feature in the SO API, it will fetch the data for each question you have answered. So the maximum limit is 10000 answers (the SO API call limit). Platform All platforms with Java 1.6. Contact You can reach me at abhinav [at] abhinavsarkar [dot] net. Please report bugs/comments/suggestions as answers to this post. Code Code was written in Clojure with the UI in Swing. It is available at https://gist.github.com/725331. It's a public gist so your can fork it if you like to do some changes.

• ROA on top of SOA

  - by Vaibhav Pujari

  I already have a stable Service Oriented Architecture for my application which exposes services as API calls. (the verbs) Now, I need to build a Resource Oriented Architecture to expose a RESTful API to interact with the application objects. (the nouns) What are the best practices to reuse the existing services: - without any persistence inside my new code. - without putting unnecessary logic into the REST layer i.e. it should ideally just leverage the services provided by SOA API. I want this layer to be as thin as possible. - without modifying the existing SOA API - allow easy extension of the REST API i.e. it should be easy to add more resources without changing the (yet to be written) core code. (I want to make resource names and their associated actions configurable so more contributors can easily add resources without a need to understand my module) Any advices/suggestions how to achieve this? Edit: Adding more info My Stack: My existing stacks is in Java. But since I plan to just use the services, I don't think that should affect the design of new REST code. I am planning to implement the new REST code in PHP. How well the services map to resources? Some services are mapped well i.e. there are services for creating, updating application objects. But for other application objects, there are no direct services available. More importantly, there are actions beyond just create, update etc. that apply to application objects. And I would like to provide some way for these actions to be exposed through REST. Since these are verbs, how do I deal with them? Where exactly I need help? I would appreciate any help towards high level design to accomplish the task along-with making the framework extendible. For instance, tomorrow there are some new services added to my SOA layer, I want to make sure it is easy for a fresh developer to write a REST call by simply registering a new resource (in a config file/db) and write code for connecting it with SOA calls. Just like plugin.

• java+netbeans+mysql+ubuntu 64 bits LTS VS C#+MS SQL for fast develop trading system

  - by crunchor

  I am going to build a trading system and use with the broker "Interactive Broker" API. The API supports C++ Socket, Java Socket, DDE, Active X APIs in Windows. The API supports Java Socket API, Posix C++ Socket API in Unix kind like Ubuntu. My trading system has some real time long calculations to do and a lot of maths for backtest. I am using a retail trading program Amibroker which is written in C++ and I run it in windows xp 32 bits, it will take me days to do one serious backtest with my G620 Sandy Bridge CPU and 3GB of ram. So for my trading system, I need to have 1. speed, 2. stability, 3. fast development I have done some research, C++ is fastest but I am not good at it and it takes much longer time to develop. Other than C++, Java in linux has the best speed. I also did some research for database and look like mysql has the best speed. Mysql and PostgreSQL both are very popular open source sql db, which one should I choose? I see MySQL has Workbench now which looks like similar to MS SQL management studio so look like a good start. Netbeans should be the most popular Java IDE now and seem like its GUI design can be as easy as Virtual Studio now. I am not sure if made by Netbeans would affect the speed and if its GUI design is really that good and easy to use. Ubuntu 64 bits LTS has good long term support, good community support, and stable. I will buy a new computer if I can create a good trading system for live trading and backtest. Very likely I will buy a I7 or I5 depends on if I7 can really have better speed for my case. Actually I mainly deal with C# in my jobs and I just knew java but not good at java. What would you guys recommend? Any better solution? This will be a big project and very likely life long project for me so I seriously do research including asking you guys before I start and focus on what I should, thanks!

• OAuth with RestSharp in Windows Phone

  - by midoBB

  Nearly every major API provider uses OAuth for the user authentication and while it is easy to understand the concept, using it in a Windows Phone app isn’t pretty straightforward. So for this quick tutorial we will be using RestSharp for WP7 and the API from getglue.com (an entertainment site) to authorize the user. So the first step is to get the OAuth request token and then we redirect our browserControl to the authorization URL private void StartLogin() {   var client = new RestClient("https://api.getglue.com/"); client.Authenticator = OAuth1Authenticator.ForRequestToken("ConsumerKey", "ConsumerSecret"); var request = new RestRequest("oauth/request_token"); client.ExecuteAsync(request, response => { _oAuthToken = GetQueryParameter(response.Content, "oauth_token"); _oAuthTokenSecret = GetQueryParameter(response.Content, "oauth_token_secret"); string authorizeUrl = "http://getglue.com/oauth/authorize" + "?oauth_token=" + _oAuthToken + "&style=mobile"; Dispatcher.BeginInvoke(() => { browserControl.Navigate(new Uri(authorizeUrl)); }); }); } private static string GetQueryParameter(string input, string parameterName) { foreach (string item in input.Split('&')) { var parts = item.Split('='); if (parts[0] == parameterName) { return parts[1]; } } return String.Empty; } Then we listen to the browser’s Navigating Event private void Navigating(Microsoft.Phone.Controls.NavigatingEventArgs e) { if (e.Uri.AbsoluteUri.Contains("oauth_callback")) { var arguments = e.Uri.AbsoluteUri.Split('?'); if (arguments.Length < 1) return; GetAccessToken(arguments[1]); } } private void GetAccessToken(string uri) { var requestToken = GetQueryParameter(uri, "oauth_token"); var client = new RestClient("https://api.getglue.com/"); client.Authenticator = OAuth1Authenticator.ForAccessToken(ConsumerKey, ConsumerSecret, _oAuthToken, _oAuthTokenSecret); var request = new RestRequest("oauth/access_token"); client.ExecuteAsync(request, response => { AccessToken = GetQueryParameter(response.Content, "oauth_token"); AccessTokenSecret = GetQueryParameter(response.Content, "oauth_token_secret"); UserId = GetQueryParameter(response.Content, "glue_userId"); }); } Now to test it we can access the user’s friends list var client = new RestClient("http://api.getglue.com/v2"); client.Authenticator = OAuth1Authenticator.ForProtectedResource(ConsumerKey, ConsumerSecret, GAccessToken, AccessTokenSecret); var request = new RestRequest("/user/friends"); request.AddParameter("userId", UserId,ParameterType.GetOrPost); // request.AddParameter("category", "all",ParameterType.GetOrPost); client.ExecuteAsync(request, response => { TreatFreindsList(); }); And that’s it now we can access all OAuth methods using RestSharp.

• Selenium Webdriver (FirefoxDriver)

  - by Samareri

  Hey all, I'm using Selenium Webdriver to do some robottesting. Since some functions appear to only work in Firefox, I'm obligated to use Firefoxdriver. Now and then, something weird happens. Starting up te driver driver = new FirefoxDriver(); driver.get(URL); gets firefox to startup but not to go to the specified url. The strange thing is that it works on another computer with the same preferences set in Firefox. I solved this problem once by changing to another version of firefox, but this time this doesn't do the trick for me, it did however worked for the other developers. Yes, the error started for all developers on the same time, same day... My first question is: is it a firefox problem or Webdriver problem. Second question: how is it possible that it works on other pc's? Any help would be very appreciated Thanks Error: org.openqa.selenium.WebDriverException: Could not parse "".

• Installing flex on Mac Parallels

  - by Ali Syed

  Hello folks, I am trying to install Flex 3 on my Windows 7 Virtual machine (parallels desktop) on my Mac Pro.

• NoPrimaryKeyException from DBUnit when loading a dataset into a databse

  - by Omar Kooheji

  I'm getting NoPrimaryKeyException when I try to run one of my unit tests which uses DBUnit. The datatable is created using Hibernate and is a join table between two classes mapping a many to many relationship. The annotations that define the relationship are as follows: @Override @ManyToMany @JoinTable(name="offset_file_offset_entries", joinColumns={@JoinColumn(name="offset_entry_id")},inverseJoinColumns={@JoinColumn(name="file_description_id")}) public List<OffsetEntry> getOffsets() { The other entries in in the XML file I'm using to define the dataset seem to work fine but not the join table. I get the following exception: org.dbunit.dataset.NoPrimaryKeyException: offset_file_offset_entries at org.dbunit.operation.UpdateOperation.getOperationData(UpdateOperation.java:72) at org.dbunit.operation.RefreshOperation$UpdateRowOperation.<init>(RefreshOperation.java:266) at org.dbunit.operation.RefreshOperation.createUpdateOperation(RefreshOperation.java:142) at org.dbunit.operation.RefreshOperation.execute(RefreshOperation.java:100) at org.dbunit.ext.mssql.InsertIdentityOperation.execute(InsertIdentityOperation.java:217) at uk.co.sabio.obscheduler.application.dao.AbstractBaseDatabaseTest.setUp(AbstractBaseDatabaseTest.java:57) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runManaged(AbstractJUnit38SpringContextTests.java:332) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.access$0(AbstractJUnit38SpringContextTests.java:326) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests$1.run(AbstractJUnit38SpringContextTests.java:216) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runTest(AbstractJUnit38SpringContextTests.java:296) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runTestTimed(AbstractJUnit38SpringContextTests.java:253) at org.springframework.test.context.junit38.AbstractJUnit38SpringContextTests.runBare(AbstractJUnit38SpringContextTests.java:213) at junit.framework.TestResult$1.protect(TestResult.java:110) at junit.framework.TestResult.runProtected(TestResult.java:128) at junit.framework.TestResult.run(TestResult.java:113) at junit.framework.TestCase.run(TestCase.java:124) at junit.framework.TestSuite.runTest(TestSuite.java:232) at junit.framework.TestSuite.run(TestSuite.java:227) at org.junit.internal.runners.JUnit38ClassRunner.run(JUnit38ClassRunner.java:83) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) the Dataset entry in question looks like this: <offset_file_offset_entries offset_entry_id="1" file_description_id="1" /> And matches up with the database which has both fields as primary keys (The Databse is MS SQL Server if that helps) There are corresponding entries in the two tables being Joined defined in the following xml: <dataset> <file_description file_path="src/test/resources/" file_pattern=".txt" file_description_id="1"/> <offset_file_description file_description_id="1"/> <offset_entries offset_entry_id="1" field_name="Field1" field_length="10" start_index="0"/> <offset_file_offset_entries offset_entry_id="1" file_description_id="1" /> </dataset> Do I have to define the primary keys in the hibernate annotations? If so How do I do so? do I have to change the way I define my dataset to imply that the two columns are a joint primary key? I'm not very proficient with hibernate or DBUnit for that matter and I'm at my wits end so any assistance would be really appreciated.

I did have a read of this article and its follow-up, but so far I've had trouble determining how to go about adding the interceptor code without the use of Spring (this is for a JUnit test). How might I go about authenticating against this Web service?

• Blackberry Development, adding dynamic number of buttons and setting Fieldchangelistener() for them

  - by Nikesh Yadav

  Hi, I am adding dynamic number of buttons in a Blackberry application and trying to get different events on each button click. I am not able to apply the setchangelistener() for these array of buttons as once the loop finishes after adding all the buttons, the events gets generated only for the last indexed button. If I make us of getIndex(), it runs fine only if I am not adding any other fields on my screen, but if I add other fields along with these array of buttons, the getIndex() function count them in the indexing as well. Can anyone please help me out in setting FieldChangeListener to array of ButtonField? Here is a sample code of the way I am using the array of ButtonField. I the code I have added two test LabelField at the top of the screen, if I remove them the code will run fine and I will get different result for each button click, but if I keep them active, the indexing gets effected and the Button wont work. package buttonclickloop; import net.rim.device.api.ui.DrawStyle; import net.rim.device.api.ui.Field; import net.rim.device.api.ui.FieldChangeListener; import net.rim.device.api.ui.component.ButtonField; import net.rim.device.api.ui.component.LabelField; import net.rim.device.api.ui.container.HorizontalFieldManager; import net.rim.device.api.ui.container.MainScreen; public class ButtoncClickLoop extends MainScreen { int i = 0; private ButtonField[] btn = new ButtonField[50]; public ButtoncClickLoop() { // TODO Auto-generated constructor stub LabelField Field1 = new LabelField("Field1"); LabelField Field2 = new LabelField("Field2",DrawStyle.RIGHT | ButtonField.USE_ALL_WIDTH); HorizontalFieldManager FieldHmgr = new HorizontalFieldManager(); FieldHmgr.add(Field1); FieldHmgr.add(Field2); FieldHmgr.setMargin(0,0,10,5); add(FieldHmgr); while (i < 3){ FieldChangeListener listener = new FieldChangeListener() { public void fieldChanged(Field field, int context) { context = field.getIndex(); if (field == btn[context]){ add(new LabelField("Label" + context + "")); } } }; btn[i] = new ButtonField("Button" + i + ""); btn[i].setChangeListener(listener); add(btn[i]); i = i + 1; } } } Thanks, Nikesh

• Accessing an object's fields without an active session

  - by Dave

  I'm using Hibernate 4.0.1.Final. Is it possible to access an object's fields if that object has been loaded via the org.hibernate.Session.load(Class clazz, Serializable id) method and there is no active session? I use this code to access an object by id … protected Object find(Class clazz, Serializable id) { Object obj = null; try { startOperation(); obj = session.load(clazz, id); tx.commit(); } catch (HibernateException e) { handleException(e); } finally { session.close(); } return obj; } but if I have that object without an active session, like with this code … final Organization foundOrg = orgDao.findById(org.getOrganizationId()); System.out.println(foundOrg.getName()); I get this error on the "System.out" line … org.hibernate.LazyInitializationException: could not initialize proxy - no Session at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:149) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:195) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:185) at org.myco.myproject.orgsclient.model.Organization_$$_javassist_0.getName(Organization_$$_javassist_0.java) at org.myco.myproject.orgsclient.dao.OrganizationDAOTest.testInsertSchool(OrganizationDAOTest.java:43) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

• Junit (3.8.1) testing that an exception is thrown (works in unit test, fails when added to a testSui

  - by Mike Cargal

  I'm trying to test that I'm throwing an exception when appropriate. In my test class I have a method similar to the following: public void testParseException() { try { ClientEntitySingleton.getInstance(); fail("should have thrown exception."); } catch (RuntimeException re) { assertEquals( "<exception message>", re.getMessage()); } } This works fine (green bar) whenever I run that single unitTest class. However, when I add that test to a testSuite, I get a red bar Unit test failure reported on the exception. One more thing... it works in the testSuite, if it's the first test in the suite. Actually, I'm doing two of these tests and just figured out that if I make them the first two tests in the suite, all is good, but I get this failure if a "regular" test precedes it. So I have a work-around, but no real answer. Any ideas? Heres'a stack trace of the "failure" java.lang.RuntimeException: ProcEntity client dn="Xxxxxx/Xxxx/XXX" is defined multiple times. at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.addClientEntity(ClientEntitySingleton.java:247) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.startElement(ClientEntitySingleton.java:264) at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanStartElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.parse(ClientEntitySingleton.java:216) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.reload(ClientEntitySingleton.java:303) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.setInputSourceProvider(ClientEntitySingleton.java:88) at com.someco.someprod.clientEntityManagement.test.TestClientBase.setUp(TestClientBase.java:17) at com.someco.someprod.clientEntityManagement.test.TestClientEntityDup.setUp(TestClientEntityDup.java:8) at junit.framework.TestCase.runBare(TestCase.java:125) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:128) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196)

• Basic Subversion questions

  - by Epitaph

  I've just started using subversion, and have read the official documentation (svn book), cheat sheet and a couple of guides. I know how to install subversion (in linux), create a repository (svnadmin create), and import my Eclipse project into the repository (SVN import), view the repository files (using svn list). But I am unable to understand some of the other terminologies. For example, after importing my Eclipse project into the newly created repository I have made changes to my Eclipse project (more than 1 file). Now, how should I update the repository with this added files/changes made to my Eclipse project? The svn update command brings the changes from the repository into your working copy - which is the opposite of what I want i.e. bring the changes I made in my Eclipse project into the previously imported project in repository. If I am correct, you update the repository more often (as you keep extending your project implementation) than your current project (with update). Also, I do not understand when would you use svn merge. The svn book states it applies the differences between 2 sources to a working copy. Is there a scenario which would explain this? Finally, can I have more than 1 project checked into the repository? Or is it better to create a new repository for each project?

• Eclipselink update existing tables

  - by javydreamercsw

  Maybe I got it wrong but i though that JPA was able to update an existing table (model changed adding a column) but is not working in my case. I can see in the logs eclipselink attempting to create it but failing because it already exists. Instead of trying an update to add the column it keeps going. (Had to remove some < so it displays) property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/jwrestling"/ property name="javax.persistence.jdbc.password" value="password"/ property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/ property name="javax.persistence.jdbc.user" value="user"/ property name="eclipselink.ddl-generation" value="create-tables"/ property name="eclipselink.logging.logger" value="org.eclipse.persistence.logging.DefaultSessionLog"/ property name="eclipselink.logging.level" value="INFO"/ And here's the table with the change (online column added) [EL Warning]: 2010-05-31 14:39:06.044--ServerSession(16053322)--Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.1.0.v20100517-r7246): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'account' already exists Error Code: 1050 Call: CREATE TABLE account (ID INTEGER NOT NULL, USERNAME VARCHAR(32) NOT NULL, SECURITY_KEY VARCHAR(255) NOT NULL, EMAIL VARCHAR(64) NOT NULL, STATUS VARCHAR(8) NOT NULL, TIMEDATE DATETIME NOT NULL, PASSWORD VARCHAR(255) NOT NULL, ONLINE TINYINT(1) default 0 NOT NULL, PRIMARY KEY (ID)) Query: DataModifyQuery(sql="CREATE TABLE account (ID INTEGER NOT NULL, USERNAME VARCHAR(32) NOT NULL, SECURITY_KEY VARCHAR(255) NOT NULL, EMAIL VARCHAR(64) NOT NULL, STATUS VARCHAR(8) NOT NULL, TIMEDATE DATETIME NOT NULL, PASSWORD VARCHAR(255) NOT NULL, ONLINE TINYINT(1) default 0 NOT NULL, PRIMARY KEY (ID))") [EL Warning]: 2010-05-31 14:39:06.074--ServerSession(16053322)--Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.1.0.v20100517-r7246): org.eclipse.persistence.exceptions.DatabaseException After this it continues with the following. Am I doing something wrong or is a bug?

• Subclipse does not recognize my project as an SVN project

  - by Nicolas Raoul

  From SVN I checked out a "myproject" folder to my hard drive. It happens to be an Eclipse project, so I imported it into Eclipse and I can work on it. I have Subclipse installed and working as expected on other projects in the same Eclipse workspace. But for some reason, "myproject" does not have the usual Subclipse controls like TeamCommit or the decorations. Did I miss any obvious steps?
