RE: Shark, Eclipse and the ClassLoader

Hi Josh, 

I Hava a simular setup in my dev Environment,

Here is a Snippet from my SharkInitialize function (This configures the
server, and loads some other properties as well)

	Properties props = new Properties();
	String path = SharkServer.class.getResource(
"/za/gov/tshwane/config/shark" ).toString().replace("file:/","");
	System.out.println("Path is " + path);
	Properties sharkServerProperties = new Properties();
	
	sharkServerProperties.load(new FileInputStream(path +
"/SharkServer.conf"));
	props.load(new FileInputStream(path + "/Shark.conf"));

	props.setProperty("enginename", SHARK_ENGINE_NAME);
			
	props = utilReplaceInProperties( props, "@@BASE@@", path );
	props = utilReplaceInProperties( props, "@@XPDL@@",
sharkServerProperties.getProperty( "SharkServer.XPDL.Location" ) );
	props = utilReplaceInProperties( props, "@@LOGS@@",
sharkServerProperties.getProperty( "SharkServer.LOGS.Location" ) );
	props = utilReplaceInProperties( props, "@@DBSV@@",
sharkServerProperties.getProperty( "SharkServer.Database.IP" ) );
			
	Shark.configure(props);


Hope this helps you

Regards

Subject: [shark] Shark, Eclipse and the ClassLoader

Hello,

   I am currently trying to develop a simple application in Eclipse that
uses Shark.  My app has one line:

       org.enhydra.shark.Shark.configure( "conf/Shark.conf" );

  This causes a nullPointerException when this code executes:

URL u=Shark.class.getClassLoader().getResource("Shark.conf.forJar");

  because for some reason, the code tries to load the default .conf file
located in the .jar file even though I am supplying my own Shark.conf file.
The problem is that the getClassLoader() function returns null.  
Sun offers some useful info:

******************************************


      getClassLoader

public ClassLoader
<http://java.sun.com/j2se/1.4.2/docs/api/java/lang/ClassLoader.html>
*getClassLoader*()

Returns the class loader for the class. Some implementations may use null to
represent the bootstrap class loader. This method will return null in such
implementations if this class was loaded by the bootstrap class loader.
******************************************


So when I use Eclipse, the getClassLoader() function returns null and throws
a fatal exception, but I can run Shark from the standard .bat files.  Any
ideas?  Anyone using Eclipse + Shark?

  Thanks, Josh Zeidner
