小编non*_*ont的帖子

昨天甲骨文决定取消java.sun.com一段时间.这对我来说很麻烦,因为xalan试图验证一些XML但无法检索properties.dtd.

我正在使用xalan 2.7.1来运行一些XSL转换,我不希望它验证任何东西.所以尝试像这样加载XSL:

SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
spf.setValidating(false);
XMLReader rdr = spf.newSAXParser().getXMLReader();      
Source xsl = new SAXSource(rdr, new InputSource(xslFilePath));  
Templates cachedXSLT  = factory.newTemplates(xsl);
Transformer transformer = cachedXSLT.newTransformer();         
transformer.transform(xmlSource, result);  

在XSL本身,我做这样的事情:

  <xsl:variable name="entry" select="document(concat($prefix, $locale_part, $suffix))/properties/entry[@key=$key]"/>

此代码检索的XML在顶部具有以下定义:

<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<entry key="...

尽管上面的java代码指示解析器不是VALIDATE,但它仍然向java.sun.com发送请求.虽然java.sun.com不可用,但这会使转换失败并显示以下消息:

 Can not load requested doc: http://java.sun.com/dtd/properties.dtd

如何让xalan停止尝试验证从"document"函数加载的XML？

我看到有一个名为Cabal的很好的包系统可以处理依赖项解析.所以我正在尝试安装它,所以我可以让它为我安装Haskell OpenGL模块.但是,Cabal本身有很多依赖.有没有办法在不手动解析所有依赖项的情况下安装Cabal？我尝试运行引导程序,但似乎没有这样做,因为它报告缺少模块parsec和网络(反过来又有自己的依赖项).

在mtl模块安装到我之前,手动构建dep让我大约3个深度:

user@machine:~/haskell/mtl-1.1.0.2$ runghc Setup build
Preprocessing library mtl-1.1.0.2...
Building mtl-1.1.0.2...

Control/Monad/Cont.hs:74:7:
    Could not find module `Control.Monad':
      Perhaps you haven't installed the profiling libraries for package base?
      Use -v to see a list of the files searched for.

我一直试图按照这个例子并使用引用来指导我,但我没有运气.

我已经定义了一个转换器:

import org.springframework.binding.convert.converters.StringToObject;

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.text.ParseException;
import java.util.Date;

public class StringToDateTwoWayConverter  extends StringToObject {
    private DateFormat format = null;

    public StringToDateTwoWayConverter () {
        super(StringToDateTwoWayConverter.class);
        format = new SimpleDateFormat("MM/dd/yyyy");

    }

    @Override
    protected Object toObject(String string, Class targetClass) throws Exception {
        Date date = null;
        try {
            date = format.parse(string);
        } catch (ParseException e) {
            e.printStackTrace();
            return null;
        }
        return date;
    }

    @Override
    protected String toString(Object object) throws Exception {
        Date date = (Date) …

我正在尝试学习Android开发,我想知道如何从麦克风中捕获音频,然后更改音频中的声音,使其听起来更浓或更清晰等等.简而言之:如何录制和更改声音的参数？(在java中,当然)

我正在尝试安装Manuel Chakravarty的加速模块，但是在使用cuda依赖项时遇到了一些麻烦。

我已经安装了NVIDIA的CUDA开发人员驱动程序和CUDA工具包。以机智：

ludflu@beefy ~/Downloads $ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver

这样安装cuda cabal模块失败：

cabal  install cuda

我正在使用D3.js渲染包含光栅图像的节点的图形.

var mainscreenURL = s3_base_url + viewController + "/screenshot.jpeg";
svg.select(".mainScreen").transition().attr("height",0).remove();

svg.append("image").attr("xlink:href", mainscreenURL)
        .attr("width", mainScreenW)
        .attr("height", mainScreenH)
        .attr("x", (w / 2) - (mainScreenW / 2)) 
        .attr("y", (h / 2) - (mainScreenH / 2)) 
        .attr("class", "mainScreen")
        .attr("id", viewController)
}); 

其中一些图像非常大,因此HTTP请求(由浏览器隐式发出)可能需要相当长的时间.我无法缓存图像,因为它们是动态生成的.

如果这是常规HTML,我会显示一个占位符图像,然后在成功完成HTTP get请求后将其换成真实的东西.但由于这是SVG,没有明确的请求,我最终得到了一个令人讨厌的破碎图像,然后被真实的东西取代.

在图像满载时,是否有任何可以挂钩的事件？

我想使用haste-compiler包来执行haskell-to-javascript的事情:

jsnavely@beefy:~/project$ cabal install haste-compiler

cabal: Error: some packages failed to install:

我注意到有一个更新版本的zip-archive将二进制版本提升到> = 0.7,它提供了这个decodeOrFail功能.因此,我尝试检查haste-compiler repo并将zip-archive版本提交到新的zip-archive 0.2.3.2.但这没有帮助:

我正在尝试使用XRPC连接到汤森路透研究员ID服务.

我的问题如下:

1)什么是XRPC？
2)发送适当的数据需要做什么

我正在做基于Spring 3注释的控制器.问题是,当验证失败时,参考数据会丢失,即countryDivisions的东西.我没有把它放在表单中,因为它不是用户可编辑的数据,这里的正统观点是只有用户可编辑的数据才会出现在表单中.我还有其他选择吗？

@Controller
public class MyInfoController {

   @Autowired
    private MyInfoFormValidator validator;

 private void loadReferenceData(ModelMap model) {
        model.put("countryDivisions",countryDivisionService.getCountryDivisionOrderedByCode());
    }

  @ModelAttribute
    private MyInfoForm loadMyInfo() {
        MyInfoForm form = new MyInfoForm();
     //load it up
    return form;
    }


    @RequestMapping(value="/editMyInfo", method = RequestMethod.GET)
    public String editMyInfo(ModelMap model ) {
        loadReferenceData(model);
        return "contactEdit";
    }

  @RequestMapping(value="/editMyInfo", method = RequestMethod.POST)
    public String saveMyInfo(ModelMap model, MyInfoForm form,BindingResult result ) {
        validator.validate (form,result);
        if (result.hasErrors()) {
            model.put("commandName", "myInfoForm");
            return "contactEdit";
        }
         //save some stuff
        return "redirect:viewMyInfo";
    }

}

我正在尝试使用Haskell解析二进制格式(PES):

import qualified Data.ByteString.Lazy as BL
import Data.Word
import Data.Word.Word24
import qualified Data.ByteString.Lazy.Char8 as L8

data Stitch = MyCoord Int Int deriving (Eq, Show)

data PESFile = PESFile {
      pecstart :: Word24
    , width :: Int
    , height :: Int
    , numColors :: Int
    , header :: String
    , stitches :: [Stitch]
    } deriving (Eq, Show)


readPES :: BL.ByteString -> Maybe PESFile
readPES bs =
        let s = L8.drop 7 bs
            pecstart = L8.readInt s in
            case pecstart of
