  Hello When I use (1) in my xhtml, I get an error as in (2). How can I access the size of an array in my bean?

• Programatically send SMS to email using Verizon Motorola Droid on Android

  - by Dave

  Hi, I was wondering if anyone knew the proper way to send an SMS message to an e-mail address using Verizon's CDMA Motorola Droid phone. The internal messaging application appears to automagically do this. While 3rd party applications like SMSPopup don't seem to be able to properly reply to e-mail addresses unless you compose the message inside the messaging application. When the internal messaging application sends a SMS message there's a corresponding 'RIL_REQUEST_CDMA_SEND_SMS' entry in the logcat (adb logcat -b radio). When you send a SMS to an e-mail address it prints the same thing, so behind the scenes it looks as though it is sending an sms. The interesting thing is that if you look at the content provider sent box the messages are addressed to various 1270XX-XXX-XXXX numbers. On other services you can send e-mail addresses by sending a SMS to a predefined short sms number. And then formatting your SMS as emailaddress subject message i.e. http://en.wikipedia.org/wiki/SMS_gateway#Carrier-Provided_SMS_to_E-Mail_Gateways For example, using T-mobile's number (500) you can send a SMS to an e-mail using the following: SmsManager smsMgr = SmsManager.getDefault(); smsMgr.sendTextMessage("500", null, "[email protected] message sent to an e-mail address from a SMS", null, null); Does anyone know if It is possible to programatically send SMS to email messages from a CDMA Android phone? Does Verizon actually send your replies as SMS messages or are they actually sent as MMS or normal http email messages? Any ideas about how to intercept what the raw message being sent to see what's going on? It might be possible that Verizon somehow generates a fake number temporarily tied to an e-mail address (since repeated messages are not sent to the same number). But, that seems pretty heavy handed. Thanks!

• Selenium RC test - IE gives 403 error on Tomcat app, Tomcat root OK

  - by Ed Daniel

  I'm new to Selenium RC, having previously used Selenium IDE and only run tests in Firefox. I'm trying to get a basic test to run using Selenium RC through Eclipse; my test works OK in Firefox, and in Safari now that I've killed the pop-up blocker, but IE8 is causing a SeleniumException to be thrown, containing an "XHR ERROR" with a 403 response: com.thoughtworks.selenium.SeleniumException: XHR ERROR: URL = http://localhost:8080/pims Response_Code = 403 Error_Message = Forbidden at com.thoughtworks.selenium.HttpCommandProcessor.throwAssertionFailureExceptionOrError(HttpCommandProcessor.java:97) at com.thoughtworks.selenium.HttpCommandProcessor.doCommand(HttpCommandProcessor.java:91) at com.thoughtworks.selenium.DefaultSelenium.open(DefaultSelenium.java:335) at org.pimslims.seleniumtest.FirstTest.testNew(FirstTest.java:32) ... I can do a similar test on http:/ /localhost:8080 (space between the slashes here because SO thinks I'm spamming) and it's fine - I can make IE open that Tomcat default page and click a link. It's only if I try to open my application at http:/ /localhost:8080/pims that I see this error - and only in IE. I can open that URL in IE by typing it into the address bar. I was convinced that there's some setting in IE that's causing this, but I've tried everything I can think of. http:/ /localhost:8080 is in my Trusted Sites, and I've turned the security for that zone down to the minimum, allowed anything that looks related to popups, etc. If I try adding http:/ /localhost:8080/pims/ to Trusted Sites, IE says it's already there. I've also messed around with proxy settings, to no avail, but may have missed something obvious. I've tried starting the test with *iexplore, *iehta, and *iexploreproxy - all behave the same. Is there something I've missed? For reference, here is my test case - this works as is, in Firefox, opening the PIMS application's index page and clicking a link: public class FirstTest extends SeleneseTestCase { @Override public void setUp() throws Exception { this.setUp("http://localhost:8080/", "*firefox"); } public void testNew() throws Exception { final Selenium s = this.selenium; s.open("/pims"); s.click("logInOutLink"); s.waitForPageToLoad("30000"); } } Any help is greatly appreciated!

• How would the conversion of a custom CMS using a text-file-based database to Drupal be tackled?

  - by James Morris

  Just today I've started using Drupal for a site I'm designing/developing. For my own site http://jwm-art.net I wrote a user-unfriendly CMS in PHP. My brief experience with Drupal is making me want to convert from the CMS I wrote. A CMS whose sole method (other than comments) of automatically publishing content is by logging in via SSH and using NANO to create a plain text file in a format like so*: head<<END_HEAD title = Audio keywords= open,source,audio,sequencing,sampling,synthesis descr = Music, noise, and audio, created by James W. Morris. parent = home END_HEAD main<<END_MAIN text<<END_TEXT Digital music, noise, and audio made exclusively with @=xlink=http://www.linux-sound.org@:Linux Audio Software@_=@. END_TEXT image=gfb@--@;Accompanying image for penonpaper-c@right ilink=audio_2008 br= ilink=audio_2007 br= ilink=audio_2006 END_MAIN info=text<<END_TEXT I've been making PC based music since the early nineties - fortunately most of it only exists as tape recordings. END_TEXT ( http://jwm-art.net/dark.php?p=audio - There's just over 400 pages on there. ) *The jounal-entry form which takes some of the work out of it, has mysteriously broken. And it still required SSH access to copy the file to the main dat dir and to check I had actually remembered the format correctly and the code hadn't mis-formatted anything (which it always does). I don't want to drop all the old content (just some), but how much work would be involved in converting it, factoring into account I've been using Drupal for a day, have not written any PHP for a couple of years, and have zero knowledge of SQL? How might a team of developers tackle this? How do-able is it for one guy in his spare time?

• How to replace openSSL calls with C# code?

  - by fonix232

  Hey there again! Today I ran into a problem when I was making a new theme creator for chrome. As you may know, Chrome uses a "new" file format, called CRX, to manage it's plugins and themes. It is a basic zip file, but a bit modified: "Cr24" + derkey + signature + zipFile And here comes the problem. There are only two CRX creators, written in Ruby or Python. I don't know neither language too much (had some basic experience in Python though, but mostly with PyS60), so I would like to ask you to help me convert this python app to a C# code that doesn't depend on external programs. Also, here is the source of crxmake.py: #!/usr/bin/python # Cribbed from http://github.com/Constellation/crxmake/blob/master/lib/crxmake.rb # and http://src.chromium.org/viewvc/chrome/trunk/src/chrome/tools/extensions/chromium_extension.py?revision=14872&content-type=text/plain&pathrev=14872 # from: http://grack.com/blog/2009/11/09/packing-chrome-extensions-in-python/ import sys from array import * from subprocess import * import os import tempfile def main(argv): arg0,dir,key,output = argv # zip up the directory input = dir + ".zip" if not os.path.exists(input): os.system("cd %(dir)s; zip -r ../%(input)s . -x '.svn/*'" % locals()) else: print "'%s' already exists using it" % input # Sign the zip file with the private key in PEM format signature = Popen(["openssl", "sha1", "-sign", key, input], stdout=PIPE).stdout.read(); # Convert the PEM key to DER (and extract the public form) for inclusion in the CRX header derkey = Popen(["openssl", "rsa", "-pubout", "-inform", "PEM", "-outform", "DER", "-in", key], stdout=PIPE).stdout.read(); out=open(output, "wb"); out.write("Cr24") # Extension file magic number header = array("l"); header.append(2); # Version 2 header.append(len(derkey)); header.append(len(signature)); header.tofile(out); out.write(derkey) out.write(signature) out.write(open(input).read()) os.unlink(input) print "Done." if __name__ == '__main__': main(sys.argv) Please could you help me?

• Problem with XML encoding of database contents with Latin characters

  - by user89691

  I have an ASP Access database that contains strings in various European languages. The database was populated prior by agents in the respective countries. It contains entries with accented etc characters as you would expect. If I open the database with MS Access these characters show up fine. For example the the German equivalent of "Open" shows as "Öffnen" (hopefully you can see an "O" with 2 dots above it!). I have ASP code that reads the database and returns records in XML. The text is passed to XMLEncode to construct the XML, but that only seems to deal with the 5 specials like "<", "&", etc. If I dump the XML the accented characters are unchanged. <English>Open</English> <German>Öffnen</German> If I look at the raw packets with Wireshark I see that the "Ö" byte is hex D6, which appears to be it's decimal Unicode and ISO 8859-1 value. The problem starts when I try to parse the XML in client-side JS. I get: "An invalid character was found in text content" from IE. FF and Chrome happily accept the XML without hiccup but the browser shows the "Ö" character as a diamond with a question mark inside. http://www.validome.org/xml/validate/ reports "encoding error." http://www.w3schools.com/dom/dom_validate.asp thinks it is fine. The XML is UTF-8 encoded. What do I need to do to have IE accept my XML without complaint? What do I need to do to have browsers display the stuff correctly?

• Mathematica regular expressions on unicode strings.

  - by dreeves

  This was a fascinating debugging experience. Can you spot the difference between the following two lines? StringReplace["–", RegularExpression@"[\\s\\S]" -> "abc"] StringReplace["-", RegularExpression@"[\\s\\S]" -> "abc"] They do very different things when you evaluate them. It turns out it's because the string being replaced in the first line consists of a unicode en dash, as opposed to a plain old ascii dash in the second line. In the case of the unicode string, the regular expression doesn't match. I meant the regex "[\s\S]" to mean "match any character (including newline)" but Mathematica apparently treats it as "match any ascii character". How can I fix the regular expression so the first line above evaluates the same as the second? Alternatively, is there an asciify filter I can apply to the strings first? PS: The Mathematica documentation says that its string pattern matching is built on top of the Perl-Compatible Regular Expressions library (http://pcre.org) so the problem I'm having may not be specific to Mathematica.

• how to compile with llvm and g++?

  - by Sriram

  Hi, I use a fedora-11 system and recently I installed llvm ( sudo yum -y install llvm llvm-docs llvm-devel ). When I search for llvm I get them in /usr/bin. some of the links to the binaries are broken(llvm-gcc,llvm-g++,llvm-cpp,etc.) the include files are found within /usr/include/llvm and libs at /usr/lib/llvm. How to compile them using g++? I tried to compile the kaleidoscope code given in the tutorial (http://llvm.org/docs/tutorial/LangImpl3.html) as per directed, but it fails to compile.. I get this... toy.cpp:5:30: error: llvm/LLVMContext.h: No such file or directory toy.cpp:352: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In member function ‘virtual llvm::Value* NumberExprAST::Codegen()’: toy.cpp:358: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In member function ‘virtual llvm::Value* BinaryExprAST::Codegen()’: toy.cpp:379: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’ toy.cpp:379: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In member function ‘llvm::Function* PrototypeAST::Codegen()’: toy.cpp:407: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’ toy.cpp:407: error: ‘getGlobalContext’ was not declared in this scope toy.cpp:408: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’ toy.cpp: In member function ‘llvm::Function* FunctionAST::Codegen()’: toy.cpp:454: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In function ‘int main()’: toy.cpp:543: error: ‘LLVMContext’ was not declared in this scope toy.cpp:543: error: ‘Context’ was not declared in this scope toy.cpp:543: error: ‘getGlobalContext’ was not declared in this scope I cannot find the LLVMContext.h file too. so i guess this might be a version problem. what should i do to make it work? some help would be good! thanks in advance... :)

• Easiest way to use speex preprocessor in C#?

  - by eselk

  I need to use the speex preprocessor, and only the preprocessor in my VOIP app (don't need to use the codec). My app is written in C#. I think I know the easiest steps, but not sure where to find these items. Easiest in my opinion, if I can find these: Windows DLL that contains only the preprocessor functions, or if small enough in size I guess the entire speex library would be OK. So far I've only found binarys in EXE format, so if I can't find the binaries I'd have to install the compiler they use to build their source and probably several other libraries (as is my experience with most open source builds). C# versions of the header files, for pinvoking the DLL functions. So my question is, does anyone know where I can find these? I'm sure people have created these before, based on the huge number of speex users, just not able to find any on-line. Hope people don't think I'm lazy, I just hate doing this kind of "busy work" if I know many others have probably already done the exact same thing :) Update: I did find http://www.rarewares.org/files/others/libspeex-dll-1.2rc1.zip which includes libspeex.dll, but the DLL has no exports so not sure how they expect that to work. The other binaries they have are also just EXEs.

• Is this possible? Overflow-y:visible with overflow-x:scroll/auto

  - by Kostrzak

  We have a problem in our team which we cannot solve :/ We made our own Grid control. When you click on the icon next to column name, the pop-up div (call it divFilter) appears and you can set filtering there. There can be dynamically generated div for each column so we can have f.e 5 divFilters in 5 different places. It works, but the only problem is that when there is for example 1-2 records on the Grid, the pop-up div will be displayed under horizontal scroll of div. We've tried with z-index but it looks like that won't work. We can set overflow:visible but we also need that horizontal scroll(our grids have up to 50 columns). We thought that we can solve it buy setting overflow-y visible and overflow-x:scroll but according to our tests and that page: http://www.brunildo.org/test/Overflowxy2.html it isn't possible(for IE7,IE8). I've also found this similar question CSS overflow-y:visible, overflow-x:scroll ,but our pop-up div must be position:absolute, because we need to position them under columns. Any ideas or workaround to it? Is it even possible to set it only with CSS without using Javascript(for dynamically changing gridview hight etc.). Thanks!!

• .NET Test Harness what should it have

  - by Conor

  Hi Folks, We have a software house developing code for us on a project, .NET Web Service (WCF) and we are also paying for a test harness to be built as a separate billable task on a daily rate. I have just joined the company and am reviewing what we are getting from the software house and wanted to know what you guys in industry thought about it? Basically what we got was a WinForm that called the w/s that had an input area (Web Service Request) to drop our XML a Submit button along with a response area for the result of the Web Response and that's it... Our internal BA has created all the xml request documents so there was no logic put into the harness around this. Looking on the Net for a definition of a Test Harness I got this: http://en.wikipedia.org/wiki/Test_harness It states it should have these 3 below things: Automate the testing process. Execute test suites of test cases. Generate associated test reports. Clearly we have got none of this apart from a partial "Automate the testing process" via a WinForm. OK, from my development background I would expect someone to Produce a WinForm as a test harness 5 years ago and really should be using some sort of Tooling around this, I explicitly told the Software House I expected some sort of tooling (NUnit,NBUnit, SOAPIU) so we could create a regression test pack for future use. [Didn’t get it but I asked for this after the requirements were signed off as I wasn’t employed then :)] Would someone be able to clarify with me if my requirement for this is over realistic, I know if I did this, I would use NUnit and TDD and then reuse the test harness as a regression test pack in future? I am interested to see what the community thought. Cheers

• In wicket, combine wicket:link with IAuthorizationStrategy

  - by seanizer

  Hi everybody. I use an IAuthorizationStrategy in wicket to limit access to certain pages. However, I also use html menus like this one: <div class="siteMenu"> <wicket:link> <a href="Page1.html" class="siteMenuLink"> <wicket:message key="pages.page1.title" /> </a> <a href="Page2.html" class="siteMenuLink"> <wicket:message key="pages.page2.title" /> </a> <a href="Page3.html" class="siteMenuLink"> <wicket:message key="pages.page3.title" /> </a> </wicket:link> </div> , that are automatically picked up and expanded using the wicket:link mechanism (like here: http://wicket.apache.org/examplenavomatic.html ). However, the IAuthorizationStrategy may not allow one or more of these target pages, so I may end up either with lots of links that lead to "permission denied" pages or lots of deactivated links (i.e. em tags or the like), neither of which is pretty. I could of course write an IComponentInstantiationListener that checks all BookmarkableLinks to see whether their target is accessible through the IAuthorizationStrategy and renders them invisible otherwise, but I wonder if there is an out-of-the-box solution to this problem. For clarification: I only use the isInstantiationAuthorized() method of IAuthorizationStrategy.

• How to use BeanTreeView?

  Hello. I have read through whole platform.netbeans.org and I do not find how to add some instance to existing children. I can add static array of diagrams(created in addNotify()), but how to add new Diagram object to the Children? I want to add it from an action that I will create(not included in code).

• x86 instruction encoding tables

  - by Cheery

  I'm in middle of rewriting my assembler. While at it I'm curious about implementing disassembly as well. I want to make it simple and compact, and there's concepts I can exploit while doing so. It is possible to determine rest of the x86 instruction encoding from opcode (maybe prefix bytes are required too, a bit). I know many people have written tables for doing it. I'm not interested about mnemonics but instruction encoding, because it is an actual hard problem there. For each opcode number I need to know: does this instruction contain modrm? how many immediate fields does this instruction have? what encoding does an immediate use? is the immediate in field an instruction pointer -relative address? what kind of registers does the modrm use for operand and register fields? sandpile.org has somewhat quite much what I'd need, but it's in format that isn't easy to parse. Before I start writing and validating those tables myself, I decided to write this question. Do you know about this kind of tables existing somewhere? In a form that doesn't require too much effort to parse.

• VS2010 compiles solution without errors, msbuild fails: "fatal error CS0002: Unable to load message string from resources"

  - by Nathan Ridley

  I'm having a lot of trouble trying to track down the cause of this error message. I have a large Visual Studio 2010 solution which compiles without error on my local machine but on the build server, msbuild fails on one of the projects with the error: fatal error CS0002: Unable to load message string from resources Here's the red error section at the end: Build FAILED. "C:\TeamCity\buildAgent\work\85eff164854b9e67\Libraries\Domainface.Proxy.Common\Domainface.Proxy.Common.csproj" (default target) (9) -> (CoreCompile target) -> CSC : fatal error CS0002: Unable to load message string from resources.

UPDATE I have just run msbuild /version on both machines and it turns out the .net framework versions are very slightly different. Local machine is 4.0.30319.488 and build server is 4.0.30319.1. I'm about to run windows update on the server to allow it to install some updates, as several seem to be .net framework-related, so I'll see if that makes a difference. UPDATE Installing the updates didn't help. Just remembered I copied up csc.exe from the async preview a little while ago in order to facilitate async compilation (the actual async preview had failed to install on the server due to visual studio not being there, but installing visual studio team viewer seems to have fixed that, so i've just run the proper async ctp3 installer to see if that makes a difference.

• JavaScript types

  - by Alex Ivasyuv

  Hi, as per http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf JavaScript has 6 types: undefined, null, boolean, string, number, object. var und; console.log(typeof und); // <-- undefined var n = null; console.log(typeof n); // <--- **object**! var b = true; console.log(typeof b); // <-- boolean var str = "myString" console.log(typeof str); // <-- string var int = 10; console.log(typeof int); // <-- number var obj = {} console.log(typeof obj); // <-- object Question 1: Why null is object type, if it has to be a null type. Question 2: What about function? var f = function() {}; console.log(typeof f); // <-- function Variable f has "function" type. Why it doesn't specified in specification as separate type. Thanks,

• best practice for directory polling

  - by Hieu Lam

  Hi all, I have to do batch processing to automate business process. I have to poll directory at regular interval to detect new files and do processing. While old files is being processed, new files can come in. For now, I use quartz scheduler and thread synchronization to ensure that only one thread can process files. Part of the code are: application-context.xml <bean id="methodInvokingJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" <property name="targetObject" ref="documentProcessor" / <property name="targetMethod" value="processDocuments" / </bean DocumentProcessor ..... public void processDocuments() { LOG.info(Thread.currentThread().getName() + " attempt to run."); if (!processing) { synchronized (this) { try { processing = true; LOG.info(Thread.currentThread().getName() + " is processing"); List xmlDocuments = documentManager.getFileNamesFromFolder(incomingFolderPath); // loop over the files and processed unlock files. for (String xmlDocument : xmlDocuments) { processDocument(xmlDocument); } } finally { processing = false; } } } } For the current code, I have to prevent other thread to process files when one thread is processing. Is that a good idea ? or we support multi-threaded processing. In that case how can I know which files is being process and which files has just arrived ? Any idea is really appreciated.

• Is it possible to handle User Defined Exception using JAX WS Dispatch API ?

  - by snowflake

  Hello, I'm performing dynamic webservices call using following code snippet: JAXBContext jc = getJAXBContext(requestClass, responseClass, jaxbContextExtraClasses); Dispatch<Object> dispatch = service.createDispatch(portQName, jc, Service.Mode.PAYLOAD); Object requestValue = getRequestValue(requestClass, pOrderedParameters); JAXBElement<?> request = new JAXBElement(new QName(serviceQNameStr, pOperationName), requestValue.getClass(), null, requestValue); Object tmpResponse = dispatch.invoke(request); Invocation works perfectly, except if I add a user defined exception on the service (a basic UserException extends java.lang.Exception). First I get: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are <{http://my.namespace/}myMethod,<{http://my.namespace/}myResponse Then I added the UserException_Exception JAX-WS generated type to my JAXB Context, and then get: Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions java.lang.StackTraceElement does not have a no-arg default constructor. this problem is related to the following location: at java.lang.StackTraceElement at public java.lang.StackTraceElement[] java.lang.Throwable.getStackTrace() at java.lang.Throwable at java.lang.Exception Only solution available I found are: dispatch directly a Soap message and handle Soap fault directly (this is the way Jboss JAX-WS implementation performs a standard JAX-WS call using services interfaces). This is not an available solution for me, I want to use a high level implementation (the more I get close to Soap message the less dynamic my code can be) usage of JAXBRIContext.ANNOTATION_READER, which is implementation specific and not an available solution for me, in order to annotate annotates java.lang.Exception as @XmlTransient The service with a user defined exception performs well using the JAX-WS generated standard client stubs and using a tool such Soap UI. Problem occurs in deserialization of the message when I have no user defined exception artifact in the JAXB context, and during invocation when I add those non JAXB compatible artifacts in the JAXB context. I'm usign Jboss WS webservice stack within Jboss 4.2.3.GA Any elegant solution to this problem is welcomed !

• Why can't I use WCF DataContract and ISerializable on the same class?

  - by Dave

  Hi all, I have a class that I need to be able to serialize to a SQLServer session variable and be available over a WCF Service. I have declared it as follows namespace MyNM { [Serializable] [DataContract(Name = "Foo", Namespace = "http://www.mydomain.co.uk")] public class Foo : IEntity, ISafeCopy<Foo> { [DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual string a { get; set; } DataMember(Order = 2)] public virtual Bar c { get; set; } /* ISafeCopy implementation */ } [Serializable] [DataContract(Name = "Bar ", Namespace = "http://www.mydomain.co.uk")] public class Bar : IEntity, ISafeCopy<Bar> { #region Implementation of IEntity DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual Baz y { get; set; } #endregion /* ISafeCopy implementation*/ } [Serializable] [DataContract] public enum Baz { [EnumMember(Value = "one")] one, [EnumMember(Value = "two")] two, [EnumMember(Value = "three")] three } But when I try and call this service, I get the following error in the trace log. "System.Runtime.Serialization.InvalidDataContractException: Type 'BarProxybcb100e8617f40ceaa832fe4bb94533c' cannot be ISerializable and have DataContractAttribute attribute." If I take out the Serializable attribute, the WCF service works, but when the object can't be serialized to session. If I remove the DataContract attribute from class Bar, the WCF service fails saying Type 'BarProxy3bb05a31167f4ba492909ec941a54533' with data contract name 'BarProxy3bb05a31167f4ba492909ec941a54533:http://schemas.datacontract.org/2004/07/' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer I've tried adding a KnownType attribute to the foo class [KnownType(typeof(Bar))] But I still get the same error. Can anyone help me out with this? Many thanks Dave

• How do I correctly install dulwich to get hg-git working on Windows?

  - by Joshua Flanagan

  I'm trying to use the hg-git Mercurial extension on Windows (Windows 7 64-bit, to be specific). I have Mercurial and Git installed. I have Python 2.5 (32-bit) installed. I followed the instructions on http://hg-git.github.com/ to install the extension. The initial easy_install failed because it was unable to compile dulwich without Visual Studio 2003. I installed dulwich manually by: git clone git://git.samba.org/jelmer/dulwich.git cd dulwich c:\Python25\python setup.py --pure install Now when I run easy_install hg-git, it succeeds (since the dulwich dependency is satisfied). In my C:\Users\username\Mercurial.ini, I have: [extensions] hgext.bookmarks = hggit = When I type 'hg' at a command prompt, I see: "* failed to import extension hggit: No module named hggit" Looking under my c:\Python25 folder, the only reference to hggit I see is Lib\site-packages\hg_git-0.2.1-py2.5.egg. Is this supposed to be extracted somewhere, or should it work as-is? Since that failed, I attempted the "more involved" instructions from the hg-git page that suggested cloning git://github.com/schacon/hg-git.git and referencing the path in my Mercurial configuration. I cloned the repo, and changed my extensions file to look like: [extensions] hgext.bookmarks = hggit = c:\code\hg-git\hggit Now when I run hg, I see: * failed to import extension hggit from c:\code\hg-git\hggit: No module named dulwich.errors. Ok, so that tells me that it is finding hggit now, because I can see in hg-git\hggit\git_handler.py that it calls from dulwich.errors import HangupException That makes me think dulwich is not installed correctly, or not in the path. Update: From Python command line: import dulwich yields Import Error: No module named dulwich However, under C:\Python25\Lib\site-packages, I do have a dulwich-0.5.0-py2.5.egg folder which appears to be populated. This was created by the steps mentioned above. Is there an additional step I need to take to make it part of the Python "path"?

• How to add DOCTYPE and xml processing instructions when marshalling with JAXB?

  - by Juha Syrjälä

  I am marshalling (serializing) JAXB beans to output stream. How can I add DOCTYPE declaration and xml processing instructions to ouput? I am doing currently marshalling like this: JAXBContext jaxbContext = JAXBContext.newInstance("com.example.package"); Marshaller marshaller = jaxbContext.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema"); Schema schema = schemaFactory.newSchema(schemaSource); marshaller.setSchema(schema); marshaller.marshal(object, output); I'd like have output that looks something like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Something SYSTEM "some.dtd"> <?xml-stylesheet type="text/xsl" href="some.xsl"?> JAXB bean are generated code so I don't want to change them. There are some undocumented tricks to add the xml processing instructions and doctype. But what is the preferred or right way to do this?

• OSMDroid simple example required

  - by Bex

  Hi! I am trying to create an app that uses offline maps and custom tiles. For this I have decided to use OSMDroid and have included the jar within my project. I will create my custom tiles using MOBAC. I have been directed to these examples: http://code.google.com/p/osmdroid/source/browse/#svn%2Ftrunk%2FOpenStreetMapViewer%2Fsrc%2Forg%2Fosmdroid%2Fsamples but I am struggling to follow them as I am new to both java and android. I have created a class file called test (which I have created following an example!): public class test extends Activity { /** Called when the activity is first created. */ protected static final String PROVIDER_NAME = LocationManager.GPS_PROVIDER; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); MapView map = (MapView) findViewById(R.id.map); map.setTileSource(TileSourceFactory.MAPQUESTOSM); map.setBuiltInZoomControls(true); map.setMultiTouchControls(true); map.getController().setZoom(16); map.getController().setCenter(new GeoPoint(30266000, -97739000)); } } with a layout file: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <org.osmdroid.views.MapView android:id="@+id/map" android:layout_width="fill_parent" android:layout_height="fill_parent" tilesource="MapquestOSM" android:layout_weight="1" /> </LinearLayout> When I run this I see no map, just an empty grid. I think this is due to my tilesource but I'm not sure what I need to change it to. Can anyone help? Bex
