Making SvnAnt use JavaSVN

Step-by-step instructions:

• Remove existing javahl.jar and svnClientAdapter.jar (libraries distirbuted with the svnant) from your Ant classpath (ANT_HOME/lib/ directory).
• Download latest version of JavaSVN library. You will need javasvn.jar and javasvn-javahl.jar files from the library distribution.
• Get patched version of svnClientAdapter.jar (version 0.9.32).
• Put javasvn.jar, javasvn-javahl.jar and svnClientAdapter-0.9.32.jar files on your Ant classpath (ANT_HOME/lib/ directory).

After performing the steps above svnant will use JavaSVN instead of JavaHL bindings.

If you have any questions regarding JavaSVN, would like to report a bug or contribute a patch, please write to support@tmatesoft.com

How do I keep the DTD from loading? Even when I turn off validation the parser tries to load the DTD file.

Even when validation is turned off, an XML parser will by default load the external DTD file in order to parse the DTD for external entity declarations. Xerces has a feature to turn off this behavior named "http://apache.org/xml/features/nonvalidating/load-external-dtd" and if you know you're using Xerces you can set this feature on the builder.

builder.setFeature(
  "http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

If you're using another parser like Crimson, your best bet is to set up an EntityResolver that resolves the DTD without actually reading the separate file.

import org.xml.sax.*;
import java.io.*;

public class NoOpEntityResolver implements EntityResolver {
  public InputSource resolveEntity(String publicId, String systemId) {
    return new InputSource(new StringBufferInputStream(""));
  }
}

Then in the builder...

builder.setEntityResolver(new NoOpEntityResolver());

There is a downside to this approach. Any entities in the document will be resolved to the empty string, and will effectively disappear. If your document has entities, you need to setExpandEntities(false) code and ensure the EntityResolver only suppresses the DocType.

这两天在修改代码中的log4j的配置。
log4j的配置有两种，一种是按照属性进行配置，一种是使用代码进行配置。
1、按照属性进行配置
按照属性进行配置可以分为按照properties格式的进行配置，一种是按照XML格式的进行配置，后者没有研究过，在此就不写了。
按照properties 的设置比较简单。使用org.apache.log4j.PropertyConfigurator类就可以了
最简单的当时是如下所示的代码了。
