• Bad crypto error in .NET 4.0

  - by Andrey

  Today I moved my web application to .net 4.0 and Forms Auth just stopped working. After several hours of digging into my SqlMembershipProvider (simplified version of built-in SqlMembershipProvider), I found that HMACSHA256 hash is not consistent. This is the encryption method: internal string EncodePassword(string pass, int passwordFormat, string salt) { if (passwordFormat == 0) // MembershipPasswordFormat.Clear return pass; byte[] bIn = Encoding.Unicode.GetBytes(pass); byte[] bSalt = Convert.FromBase64String(salt); byte[] bAll = new byte[bSalt.Length + bIn.Length]; byte[] bRet = null; Buffer.BlockCopy(bSalt, 0, bAll, 0, bSalt.Length); Buffer.BlockCopy(bIn, 0, bAll, bSalt.Length, bIn.Length); if (passwordFormat == 1) { // MembershipPasswordFormat.Hashed HashAlgorithm s = HashAlgorithm.Create( Membership.HashAlgorithmType ); bRet = s.ComputeHash(bAll); } else { bRet = EncryptPassword( bAll ); } return Convert.ToBase64String(bRet); } Passing the same password and salt twice returns different results!!! It was working perfectly in .NET 3.5 Anyone aware of any breaking changes, or is it a known bug? UPDATE: When I specify SHA512 as hashing algorithm, everything works fine, so I do believe it's a bug in .NET 4.0 crypto Thanks! Andrey

• Poor LLVM JIT performance

  - by Paul J. Lucas

  I have a legacy C++ application that constructs a tree of C++ objects. I want to use LLVM to call class constructors to create said tree. The generated LLVM code is fairly straight-forward and looks repeated sequences of: ; ... %11 = getelementptr [11 x i8*]* %Value_array1, i64 0, i64 1 %12 = call i8* @T_string_M_new_A_2Pv(i8* %heap, i8* getelementptr inbounds ([10 x i8]* @0, i64 0, i64 0)) %13 = call i8* @T_QueryLoc_M_new_A_2Pv4i(i8* %heap, i8* %12, i32 1, i32 1, i32 4, i32 5) %14 = call i8* @T_GlobalEnvironment_M_getItemFactory_A_Pv(i8* %heap) %15 = call i8* @T_xs_integer_M_new_A_Pvl(i8* %heap, i64 2) %16 = call i8* @T_ItemFactory_M_createInteger_A_3Pv(i8* %heap, i8* %14, i8* %15) %17 = call i8* @T_SingletonIterator_M_new_A_4Pv(i8* %heap, i8* %2, i8* %13, i8* %16) store i8* %17, i8** %11, align 8 ; ... Where each T_ function is a C "thunk" that calls some C++ constructor, e.g.: void* T_string_M_new_A_2Pv( void *v_value ) { string *const value = static_cast<string*>( v_value ); return new string( value ); } The thunks are necessary, of course, because LLVM knows nothing about C++. The T_ functions are added to the ExecutionEngine in use via ExecutionEngine::addGlobalMapping(). When this code is JIT'd, the performance of the JIT'ing itself is very poor. I've generated a call-graph using kcachegrind. I don't understand all the numbers (and this PDF seems not to include commas where it should), but if you look at the left fork, the bottom two ovals, Schedule... is called 16K times and setHeightToAtLeas... is called 37K times. On the right fork, RAGreed... is called 35K times. Those are far too many calls to anything for what's mostly a simple sequence of call LLVM instructions. Something seems horribly wrong. Any ideas on how to improve the performance of the JIT'ing?

• Problem with Unit testing of ASP.NET project (NullReferenceException when running the test)

  - by Alex

  Hi, I'm trying to create a bunch of MS visual studio unit tests for my n-tiered web app but for some reason I can't run those tests and I get the following error - "Object reference not set to an instance of an object" What I'm trying to do is testing of my data access layer where I use LINQ data context class to execute a certain function and return a result,however during the debugging process I found out that all the tests fail as soon as they get to the LINQ data context class and it has something to do with the connection string but I cant figure out what is the problem. The debugging of tests fails here(the second line): public EICDataClassesDataContext() : base(global::System.Configuration.ConfigurationManager.ConnectionStrings["EICDatabaseConnectionString"].ConnectionString, mappingSource) { OnCreated(); } And my test is as follows: TestMethod()] public void OnGetCustomerIDTest() { FrontLineStaffDataAccess target = new FrontLineStaffDataAccess(); // TODO: Initialize to an appropriate value string regNo = "jonh"; // TODO: Initialize to an appropriate value int expected = 10; // TODO: Initialize to an appropriate value int actual; actual = target.OnGetCustomerID(regNo); Assert.AreEqual(expected, actual); } The method which I call from DAL is: public int OnGetCustomerID(string regNo) { using (LINQDataAccess.EICDataClassesDataContext dataContext = new LINQDataAccess.EICDataClassesDataContext()) { IEnumerable<LINQDataAccess.GetCustomerIDResult> sProcCustomerIDResult = dataContext.GetCustomerID(regNo); int customerID = sProcCustomerIDResult.First().CustomerID; return customerID; } } So basically everything fails after it reaches the 1st line of DA layer method and when it tries to instantiate the LINQ data access class... I've spent around 10 hours trying to troubleshoot the problem but no result...I would really appreciate any help! UPDATE: Finally I've fixed this!!!!:) I dont know why but for some reasons in the app.config file the connection to my database was as follows: AttachDbFilename=|DataDirectory|\EICDatabase.MDF So what I did is I just changed the path and instead of |DataDirectory| I put the actual path where my MDF file sits,i.e C:\Users\1\Documents\Visual Studio 2008\Projects\EICWebSystem\EICWebSystem\App_Data\EICDatabase.mdf After I had done that it worked out!But still it's a bit not clear what was the problem...probably incorrect path to the database?My web.config of ASP.NET project contains the |DataDirectory|\EICDatabase.MDF path though..

• Help decrypting in ColdFusion passwords created in .NET

  - by KnightStalker

  I have a SQL db storing passwords that were encrypted through a .NET application, that I need to decrypt through a ColdFusion app. I just can't seem to get things set upproperly for the CF decryption to work. Any help would by appreciated. Thanks. The .NET decryption code is: public string Decrypt(string input) { try { DESCryptoServiceProvider des = new DESCryptoServiceProvider(); int ZeroBasedByteCount = (input.Length / 2); //Put the input string into the byte array byte[] inputByteArray = new byte[ZeroBasedByteCount]; int i; int x; for (x = 0;x<ZeroBasedByteCount;x++) { i = (Convert.ToInt32(input.Substring(x * 2, 2), 16)); inputByteArray[x] = (byte)i; } //Create the crypto objects des.Key = ASCIIEncoding.ASCII.GetBytes(key); des.IV = ASCIIEncoding.ASCII.GetBytes(key); MemoryStream ms = new MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(), CryptoStreamMode.Write); //Flush the data through the crypto stream into the memory stream cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); //Get the decrypted data back from the memory stream StringBuilder ret = new StringBuilder(); foreach(byte b in ms.ToArray()) { ret.Append((char)b); } return ret.ToString(); } catch(Exception ex) { throw(ex); return null; } }

• Is is possible to populate a datatable using a Lambda expression(C#3.0)

  - by deepak.kumar.goyal

  I have a datatable. I am populating some values into that. e.g. DataTable dt =new DataTable(); dt.Columns.Add("Col1",typeof(int)); dt.Columns.Add("Col2",typeof(string)); dt.Columns.Add("Col3",typeof(DateTime)); dt.Columns.Add("Col4",typeof(bool)); for(int i=0;i< 10;i++) dt.Rows.Add(i,"String" + i.toString(),DateTime.Now,(i%2 == 0)?true:false); There is nothing wrong in this program and gives me the expected output. However, recently , I am learning Lambda and has done some basic knowledge. With that I was trying to do the same thing as under Enumerable.Range(0,9).Select(i = > { dt.Rows.Add(i,"String" + i.toString(),DateTime.Now,(i%2 == 0)?true:false); }); But I am unsuccessful. Is my approach correct(Yes I know that I am getting compile time error; since not enough knowledge on the subject so far)? Can we achieve this by the way I am doing is a big doubt(as I donot know.. just giving a shot). If so , can some one please help me in this regard. I am using C#3.0 and dotnet framework 3.5 Thanks

• C# 4.0: casting dynamic to static

  - by Kevin Won

  This is an offshoot question that's related to another I asked here. I'm splitting it off because it's really a sub-question: I'm having difficulties casting an object of type dynamic to another (known) static type. I have an ironPython script that is doing this: import clr clr.AddReference("System") from System import * def GetBclUri(): return Uri("http://google.com") note that it's simply newing up a BCL System.Uri type and returning it. So I know the static type of the returned object. now over in C# land, I'm newing up the script hosting stuff and calling this getter to return the Uri object: dynamic uri = scriptEngine.GetBclUri(); System.Uri u = uri as System.Uri; // casts the dynamic to static fine Works no problem. I now can use the strongly typed Uri object as if it was originally instantiated statically. however.... Now I want to define my own C# class that will be newed up in dynamic-land just like I did with the Uri. My simple C# class: namespace Entity { public class TestPy // stupid simple test class of my own { public string DoSomething(string something) { return something; } } } Now in Python, new up an object of this type and return it: sys.path.append(r'C:..path here...') clr.AddReferenceToFile("entity.dll") import Entity.TestPy def GetTest(): return Entity.TestPy(); // the C# class then in C# call the getter: dynamic test = scriptEngine.GetTest(); Entity.TestPy t = test as Entity.TestPy; // t==null!!! here, the cast does not work. Note that the 'test' object (dynamic) is valid--I can call the DoSomething()--it just won't cast to the known static type string s = test.DoSomething("asdf"); // dynamic object works fine so I'm perplexed. the BCL type System.Uri will cast from a dynamic type to the correct static one, but my own type won't. There's obviously something I'm not getting about this...

• Why ClassCastException on JMS ConnectionFactory lookup in JNDI?

  - by Derek Mahar

  What might be the cause of the following ClassCastException in a standalone JMS client application when it attempts to retrieve a connection factory from the JNDI provider? Exception in thread "main" java.lang.ClassCastException: javax.naming.Reference cannot be cast to javax.jms.ConnectionFactory Here is an abbreviated version of the JMS client that includes only its start() and stop() methods. The exception occurs on the first line in method start() which attempts to retrieve the connection factory from the JNDI provider, a remote LDAP server. The JMS connection factory and destination objects are on a remote JMS server. class JmsClient { private ConnectionFactory connectionFactory; private Connection connection; private Session session; private MessageConsumer consumer; private Topic topic; public void stop() throws JMSException { consumer.close(); session.close(); connection.close(); } public void start(Context context, String connectionFactoryName, String topicName) throws NamingException, JMSException { // ClassCastException occurs when retrieving connection factory. connectionFactory = (ConnectionFactory) context.lookup(connectionFactoryName); connection = connectionFactory.createConnection("username","password"); session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); topic = (Topic) context.lookup(topicName); consumer = session.createConsumer(topic); connection.start(); } private static Context getInitialContext() throws NamingException, IOException { String filename = "context.properties"; Properties props = new Properties(); props.load(new FileInputStream(filename)); return new InitialContext(props); } }

• Calling ASP.NET Web API using JQuery ajax - cross site scripting issue

  - by SimonF

  I have a Web API which I am calling using the JQuery ajax function. When I test the service directly (using the Chrome RESTEasy extension) it works fine, however when I call it using the JQuery ajax function I get an error. I'm calling it on port 81: $.ajax({ url: "http://127.0.0.1:81/api/people", data: JSON.stringify(personToCreate), type: "POST", contentType: "application/json;charset=utf-8", statusCode: { 201: function (newPerson) { callback(newPerson); } }, success: function (newPerson) { alert("New person created with an Id of " + newPerson.Id); }, error: function (jqXHR, textStatus, errorThrown) { alert('Error. '+textStatus+'. '+errorThrown); } }); ...but when I trace it using FireBug Lite the response comes from port 82: {"Message":"No HTTP resource was found that matches the request URI 'http://127.0.0.1:82/api/people'.","MessageDetail":"No action was found on the controller 'People' that matches the request."} I think the error is, effectively, due to cross-site scripting being blocked, but I'm not actually cross-site scripting, if you see what I mean. Has anyone else come across this and been able to fix it? Edit: Routing config (global.asax.vb) is: RouteTable.Routes.MapHttpRoute(name:="DefaultApi", routeTemplate:="api/{controller}/{id}", defaults:=New With {Key .id = System.Web.Http.RouteParameter.Optional}) Controller: Public Function PostValue(ByVal departmentid As Integer, ByVal emailaddress As String, ByVal firstname As String, ByVal lastname As String) As Guid Dim context As New WSMModelDataContext Dim bllPeople As New PeopleBLL(context) Return bllPeople.Create(firstname, lastname, emailaddress, departmentid) End Function When I debug it, it doesn't get as far as running the controller, although when calling it through RESTEasy it routes correctly and the controller executes successfully. The only difference seemes to be that wen called through RESTEasy it is (correctly) using http://127.0.0.1:81 but for some reason when called via JQuery/ajax it seems to be using http://127.0.0.1:82.

• Wrapping FUSE from Go

  - by Matt Joiner

  I'm playing around with wrapping FUSE with Go. However I've come stuck with how to deal with struct fuse_operations. I can't seem to expose the operations struct by declaring type Operations C.struct_fuse_operations as the members are lower case, and my pure-Go sources would have to use C-hackery to set the members anyway. My first error in this case is "can't set getattr" in what looks to be the Go equivalent of a default copy constructor. My next attempt is to expose an interface that expects GetAttr, ReadLink etc, and then generate C.struct_fuse_operations and bind the function pointers to closures that call the given interface. This is what I've got (explanation continues after code): package fuse // #include <fuse.h> // #include <stdlib.h> import "C" import ( //"fmt" "os" "unsafe" ) type Operations interface { GetAttr(string, *os.FileInfo) int } func Main(args []string, ops Operations) int { argv := make([]*C.char, len(args) + 1) for i, s := range args { p := C.CString(s) defer C.free(unsafe.Pointer(p)) argv[i] = p } cop := new(C.struct_fuse_operations) cop.getattr = func(*C.char, *C.struct_stat) int {} argc := C.int(len(args)) return int(C.fuse_main_real(argc, &argv[0], cop, C.size_t(unsafe.Sizeof(cop)), nil)) } package main import ( "fmt" "fuse" "os" ) type CpfsOps struct { a int } func (me *CpfsOps) GetAttr(string, *os.FileInfo) int { return -1; } func main() { fmt.Println(os.Args) ops := &CpfsOps{} fmt.Println("fuse main returned", fuse.Main(os.Args, ops)) } This gives the following error: fuse.go:21[fuse.cgo1.go:23]: cannot use func literal (type func(*_Ctype_char, *_Ctype_struct_stat) int) as type *[0]uint8 in assignment I'm not sure what to pass to these members of C.struct_fuse_operations, and I've seen mention in a few places it's not possible to call from C back into Go code. If it is possible, what should I do? How can I provide the "default" values for interface functions that acts as though the corresponding C.struct_fuse_operations member is set to NULL?

• How can i ignore map property in NHibernate with setter

  i need ignore map property with setter in NHibernate, because the relationship between entities is required. this is my simple model public class Person { public virtual Guid PersonId { get; set; } public virtual string FirstName { get; set; } public virtual string SecondName { get; set; } //this is the property that do not want to map public Credential Credential { get; set; } } public class Credential { public string CodeAccess { get; set; } public bool EsPremium { get; set; } } public sealed class PersonMap : ClassMapping<Person> { public PersonMap() { Table("Person"); Cache(x => x.Usage(CacheUsage.ReadWrite)); Id(x => x.Id, m => { m.Generator(Generators.GuidComb); m.Column("PersonId"); }); Property(x => x.FirstName, map => { map.NotNullable(true); map.Length(255); }); Property(x => x.SecondName, map => { map.NotNullable(true); map.Length(255); }); } } I know that if I leave the property Credential {get;} I was not going to take the map of NHibernate, but I need to set the value. Thanks in advance.

• Workaround for basic syntax not being parsed.

  - by Mark Tomlin

  I want to have a class property that allow for an expression to take place on the right side of the equals sign. All versions of PHP choke on the following code, but it is written in this way to allow for easier extendibility in the future. /* Example SDK Class */ class SDK { /* Runtime Option Flags */ // Strings # 0: Makes no change to the strings. var $STRING_NONE = (1 << 0); # 1: Removes color codes from the string. var $STRING_STRIP_COLOR = (1 << 1); # 2: Removes language codes from the string. var $STRING_STRIP_LANG = (1 << 2); # 3: Removes all formatting from the string. var $STRING_STRIP = SELF::STRING_STRIP_COLOR & SELF::STRING_STRIP_LANG; # 4: Converts color codes to HTML & UTF-8. var $STRING_HTML = (1 << 3); # 8: Converts color codes to ECMA-48 escape color codes & UTF-8. var $STRING_CONSOLE = (1 << 4); # 16: Changes player names only. var $STRING_NAMES = (1 << 5); # 32: Changes host names only. var $STRING_HOSTS = (1 << 6); function SDK($fString = SELF::STRING_HTML & SELF::STRING_NAMES & SELF_HOST) { // constructor code. } } $SDK &= new SDK(SDK::STRING_NONE); (1 << 0) seems like very basic syntax to me, and is not fathomable why PHP would not allow for such a thing. Can anyone think of a work around that would maintain readability and future expandability of the following code?

• Comparable and Comparator contract with regards to null

  - by polygenelubricants

  Comparable contract specifies that e.compareTo(null) must throw NullPointerException. From the API: Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false. On the other hand, Comparator API mentions nothing about what needs to happen when comparing null. Consider the following attempt of a generic method that takes a Comparable, and return a Comparator for it that puts null as the minimum element. static <T extends Comparable<? super T>> Comparator<T> nullComparableComparator() { return new Comparator<T>() { @Override public int compare(T el1, T el2) { return el1 == null ? -1 : el2 == null ? +1 : el1.compareTo(el2); } }; } This allows us to do the following: List<Integer> numbers = new ArrayList<Integer>( Arrays.asList(3, 2, 1, null, null, 0) ); Comparator<Integer> numbersComp = nullComparableComparator(); Collections.sort(numbers, numbersComp); System.out.println(numbers); // "[null, null, 0, 1, 2, 3]" List<String> names = new ArrayList<String>( Arrays.asList("Bob", null, "Alice", "Carol") ); Comparator<String> namesComp = nullComparableComparator(); Collections.sort(names, namesComp); System.out.println(names); // "[null, Alice, Bob, Carol]" So the questions are: Is this an acceptable use of a Comparator, or is it violating an unwritten rule regarding comparing null and throwing NullPointerException? Is it ever a good idea to even have to sort a List containing null elements, or is that a sure sign of a design error?

• Mapping Cassandra Super Columns

  - by Laubstein

  Hello dudes, I guess everybody that played with Cassandra already read this article. I trying to create my schema on CassandraCli, but I am having a lot of problems, can someone guide me to the right way? I am trying to create a similar structure like the Comments column family from the article. In CassandraCli terminal I type: create column family posts with column_type = ‘Super’ and comparator = ‘AsciiType’ and subcomparator = TimeUUIDType; It works fine, there is no doc telling me that if I add a column_metadata attribute those will be for the super columns cause my column family is of type super, i can’t find if it is true so: create column family posts with column_type = ‘Super’ and comparator = ‘AsciiType’ and subcomparator = ‘TimeUUIDType’ and column_metadata = [{column_name:'body'}]; I am trying to create the same as the comment column family of the article, but when i try to populate set posts['post1'][timeuuid()][body] = ‘Hello I am Goku!’; i got: Invalid UUID string: body I guess because i chose the subcomparator be of type timeuuid and the body is a string, it should be a timeuuid, so HOW my columns inside the super column which is the type timeuuid could holds columns with string type names as the comments of the article are created? Thanks

• How do I associate Parameters to Command objects in ADO with VBScript?

  - by Krashman5k

  I have been working an ADO VBScript that needs to accept parameters and incorporate those parameters in the Query string that gets passed the the database. I keep getting errors when the Record Set Object attempts to open. If I pass a query without parameters, the recordset opens and I can work with the data. When I run the script through a debugger, the command object does not show a value for the parameter object. It seems to me that I am missing something that associates the Command object and Parameter object, but I do not know what. Here is a bit of the VBScript Code: ... 'Open Text file to collect SQL query string' Set fso = CreateObject("Scripting.FileSystemObject") fileName = "C:\SQLFUN\Limits_ADO.sql" Set tso = fso.OpenTextFile(fileName, FORREADING) SQL = tso.ReadAll 'Create ADO instance' connString = "DRIVER={SQL Server};SERVER=myserver;UID=MyName;PWD=notapassword; Database=favoriteDB" Set connection = CreateObject("ADODB.Connection") Set cmd = CreateObject("ADODB.Command") connection.Open connString cmd.ActiveConnection = connection cmd.CommandText = SQL cmd.CommandType = adCmdText Set paramTotals = cmd.CreateParameter With paramTotals .value = "tot%" .Name = "Param1" End With 'The error occurs on the next line' Set recordset = cmd.Execute If recordset.EOF then WScript.Echo "No Data Returned" Else Do Until recordset.EOF WScript.Echo recordset.Fields.Item(0) ' & vbTab & recordset.Fields.Item(1) recordset.MoveNext Loop End If The SQL string that I use is fairly standard except I want to pass a parameter to it. It is something like this: SELECT column1 FROM table1 WHERE column1 IS LIKE ? I understand that ADO should replace the "?" with the parameter value I assign in the script. The problem I am seeing is that the Parameter object shows the correct value, but the command object's parameter field is null according to my debugger.

• How do I avoid repetition in Java ResourceBundle strings?

  - by Trejkaz

  We had a lot of strings which contained the same sub-string, from sentences about checking the log or how to contact support, to branding-like strings containing the company or product name. The repetition was causing a few issues for ourselves (primarily typos or copy/paste errors) but it also causes issues in that it increases the amount of text our translator has to translate. The solution I came up with went something like this: public class ExpandingResourceBundleControl extends ResourceBundle.Control { public static final ResourceBundle.Control EXPANDING = new ExpandingResourceBundleControl(); private ExpandingResourceBundleControl() { } @Override public ResourceBundle newBundle(String baseName, Locale locale, String format, ClassLoader loader, boolean reload) throws IllegalAccessException, InstantiationException, IOException { ResourceBundle inner = super.newBundle(baseName, locale, format, loader, reload); return inner == null ? null : new ExpandingResourceBundle(inner, loader); } } ExpandingResourceBundle delegates to the real resource bundle but performs conversion of {{this.kind.of.thing}} to look up the key in the resources. Every time you want to get one of these, you have to go: ResourceBundle.getBundle("com/acme/app/Bundle", EXPANDING); And this works fine -- for a while. What eventually happens is that some new code (in our case autogenerated code which was spat out of Matisse) looks up the same resource bundle without specifying the custom control. This appears to be non-reproducible if you write a simple unit test which calls it with and then without, but it occurs when the application is run for real. Somehow the cache inside ResourceBundle ejects the good value and replaces it with the broken one. I am yet to figure out why and Sun's jar files were compiled without debug info so debugging it is a chore. My questions: Is there some way of globally setting the default ResourceBundle.Control that I might not be aware of? That would solve everything rather elegantly. Is there some other way of handling this kind of thing elegantly, perhaps without tampering with the ResourceBundle classes at all?

  - by Jess

  We are trying to figure out how to setup Dependency Injection for situations where service classes can have different dependencies based on how they are used. In our specific case, we have a web app where 95% of the time the connection string is the same for the entire Request (this is a web application), but sometimes it can change. For example, we might have 2 classes with the following dependencies (simplified version - service actually has 4 dependencies): public LoginService (IUserRepository userRep) { } public UserRepository (IContext dbContext) { } In our IoC container, most of our dependencies are auto-wired except the Context for which I have something like this (not actual code, it's from memory ... this is StructureMap): x.ForRequestedType().Use() .WithCtorArg("connectionString").EqualTo(Session["ConnString"]); For 95% of our web application, this works perfectly. However, we have some admin-type functions that must operate across thousands of databases (one per client). Basically, we'd want to do this: public CreateUserList(IList<string> connStrings) { foreach (connString in connStrings) { //first create dependency graph using new connection string ???? //then call service method on new database _loginService.GetReportDataForAllUsers(); } } My question is: How do we create that new dependency graph for each time through the loop, while maintaining something that can easily be tested?

• Liferay hook: filter url giving filterstart error and current url generates exception null

  - by jack

  I'm trying to make an autologinfilter in Eclipse using a liferay hook. Now I've added the: <filter> <filter-name>myautologinfilter</filter-name> <filter-class>bla.bla.xyz</filter-class> </filter> <filter-mapping> <filter-name>myautologinfilter</filter-name> <url-pattern>/c/login/myurl</url-pattern> </filter-mapping> To the liferay hook's web.xml. In the liferay-hook.xml I added: portal.properties And in that hook.xml I added: auto.login.hooks=bla.bla.xyz bla.bla.xyz implements AutoLogin, but for now it's pretty gutted: @Override public String[] login(HttpServletRequest request, HttpServletResponse response) throws AutoLoginException { Object parameters = request.getAttribute("javax.servlet.forward.query_string"); Map<String, String> x = parserClass.parsing(parameters.toString()); System.out.println("voornaam: " + geparsdeParameters.get("tokenvalue1")); try { return null; } catch (Exception e) { throw new AutoLoginException(e); } } Since the hook doesn't start when I add the filtering I removed it and just tried: http://localhost:8080/c/portal/login?tokenvalue1=55 but when I check my tomcat I see: Error XYZ Url: url myUsedUrl exception null Also I tried adding some util classes but I got: classnotfoundexceptions. Is there anything specific I have to do when I add extra classes in a hook? Any advice/input would be appreciated. Or someone's ear I could lend so I could mail them a little bit so I could pick their brain a bit would be really appreciated since I don't know anyone who programs for liferay.

  Iam trying to get a location (latitute and longitude), I cant figure out what Im doing wrong but my location keeps returning null. Anybody knows what I am doing wrong? public class ParseJSON extends Activity implements LocationListener { private TextView latituteField; private TextView longitudeField; LocationManager lm; String provider; int lat; int lon; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.test); lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Criteria crit = new Criteria(); provider = lm.getBestProvider(crit, false); Location location = lm.getLastKnownLocation(provider); if (location != null){ lat = (int) location.getLatitude(); lon = (int) location.getLongitude(); latituteField = (TextView) findViewById(R.id.lattest); longitudeField = (TextView) findViewById(R.id.lontest); latituteField.setText(lat); longitudeField.setText(String.valueOf(lon)); } else { Toast.makeText(ParseJSON.this, "Couldnt get location", Toast.LENGTH_SHORT); } String readWeatherFeed = readWeatherFeed(); try { JSONArray jsonArray = new JSONArray(readWeatherFeed); Log.i(ParseJSON.class.getName(), "Number of entries " + jsonArray.length()); for (int i = 0; i < jsonArray.length(); i++) { JSONObject jsonObject = jsonArray.getJSONObject(i); Log.i(ParseJSON.class.getName(), jsonObject.getString("text")); } } catch (Exception e) { e.printStackTrace(); } } I dont have a clue, thanks in advance

• How to improve Java performance on Informix for Windows

  - by Michal Niklas

  I have problem with performance of Java UDR functions on Informix on Windows. On this server I already have some functions in C and SPL. I chose one function to write it in those 3 languages and I measured performance of this function on test table. Function calculates some kind of checksum so it does not use any db libraries etc. only string and math operations. I observed performance on 30k records with SQL like: select function(txt) from _tmp_perf_test and I changed function to 'function_c, function_spl or function_java. My performance tests showed that C function is the fastest, SPL function is about 5 times slower, where Java is 100 (one hundred!) times slower than C. I checked it few times and 1:100 ratio didn't improve. I changed Java function to simply return length of the string but even this do not help so it looks, that there is general problem with Java function invocation, because there was no difference in time between Java function that calculate checksum and Java function that returns length of the string. I increased JVM_MAX_HEAP_SIZE to 128 and it not helped too. I use IBM Informix Dynamic Server Version 11.50.TC6DE. The same test on Linux server: IBM Informix Dynamic Server Version 11.50.FC6 show more "normal" results, i.e. Java is slower from C and SPL but only 2 to 5 times. What can I do to improve Java performance on Informix server on Windows?

• I get an Exception when trying to implement reset password with Authlogic

  - by Tam

  Hi, I'm using Ruby on Rails 2.3.5 and Ruby 1.9 and implmeneted Authlogic as my authentication engine. Authlogic works fine. But now I have been trying to implement password reset using the following tutorial: http://www.binarylogic.com/2008/11/16/tutorial-reset-passwords-with-authlogic/ But I'm getting the following exception when I type mysite.com/password_resets/new Processing PasswordResetsController#new (for 127.0.0.1 at 2010-03-13 01:09:45) [GET] Completed in 9ms (DB: 0) | 200 [http://localhost/password_resets/new] [2010-03-13 01:09:45] ERROR TypeError: can't convert Array into String /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/activesupport-2.3.5/lib/active_support/core_ext/string/output_safety.rb:34:in `concat' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/activesupport-2.3.5/lib/active_support/core_ext/string/output_safety.rb:34:in `concat_with_safety' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/rack-1.0.1/lib/rack/handler/webrick.rb:63:in `block in service' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/response.rb:158:in `each' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/response.rb:158:in `each' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/string_coercion.rb:16:in `send' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/string_coercion.rb:16:in `method_missing' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/reloader.rb:22:in `method_missing' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/rack-1.0.1/lib/rack/handler/webrick.rb:62:in `service' /Users/tammam56/.rvm/rubies/ruby-1.9.1-p378/lib/ruby/1.9.1/webrick/httpserver.rb:111:in `service' /Users/tammam56/.rvm/rubies/ruby-1.9.1-p378/lib/ruby/1.9.1/webrick/httpserver.rb:70:in `run' /Users/tammam56/.rvm/rubies/ruby-1.9.1-p378/lib/ruby/1.9.1/webrick/server.rb:183:in `block in start_thread' Honestly I'm not sure where to start debugging for this. Is it because I'm using Ruby 1.9? some people seem to be having trouble with Authlogic and Ruby 1.9: http://isitruby19.com/authlogic Please advise me how to go about solving/debugging this issues? Thanks, Tam

• How to fluent-map this (using fluent nhibernate)?

  - by vikasde

  I have two tables in my database "Styles" and "BannedStyles". They have a reference via the ItemNo. Now styles can be banned per store. So if style x is banned at store Y then its very possible that its not banned at store Z or vice verse. What is the best way now to map this to a single entity? Should I be mapping this to a single entity? My Style entity looks like this: public class Style { public virtual int ItemNo { get; set;} public virtual string SKU { get; set; } public virtual string StyleName { get; set; } public virtual string Description { get; set; } public virtual Store Store { get; set; } public virtual bool IsEntireStyleBanned { get; set; } }

• Generate a Version.java file in Maven

  - by Ralph

  I have a Java project that I build using an Ant script. I am trying to convert the project to Maven. One of the tasks generates a Java source file called Version.java that contains a static String representation of the compilation timestamp, as follows: package com.foo.bar; public final class Version { public static String VERSION="100301.1046"; } The Ant task is very simple: <target name="version" depends="init" description="Create Version.java"> <echo file="src/${package.dir}/Version.java" message="package ${package.name};${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message="public final class Version {${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message=" public static String VERSION=&quot;${buildtime}&quot;;${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message="}${line.separator}" /> <echo message="BUILD ${buildtime}" /> </target> Is it possible to do something similar in Maven, using generate-sources, or some other simple method?
