	}

i get the sample code from the sdn sap, when i run the sample it works well,

but if i want to get the absolute path instead of "/" context

for instance c:
logon.properties or /WEB-INF/logon.properties in tomcat how i going to do this

logon.properties

jco.client.client=100

jco.client.user=cpic_sms

jco.client.passwd=exxx

jco.client.language=EN

jco.client.ashost=emi-sap

jco.client.sysnr=00

Have a look at the ServletContext object. This object has a method getRealPath() hat allows to find out the exact path of your application. So, if you want to get the path for WEB-INF/logon.properties, try something like this:

String filename = getServletContext().getRealPath("/") + "WEB-INF/logon.properties";

If you don't work in a servlet context, it is also possible to access files with

this.getClass().getClassLoader().getResourceAsStream(
				"my/package/name/some.file");

Hi,

You can do this by creating a FileInputStream with absolute path of the property file. The only thing you need to do is, you need to override the <b>load</b> with InputStream.

public void load(InputStream inputS)

{

orderProperties.load(inputS);

}

//Create FileInputStream

FileInputStream fileIn = new FileInputStream("c:
logon.properties ");

//call your custom method..

obj.load(fileIn);

If you keep files under Web-Inf, tomcat automatically identifies the .properties. You need not to create FileInputStream for this case.

public JCOConnection(LogOnInfo logOnInfo){
		JCO.Pool pool = JCO.getClientPoolManager().getPool(connectionPool);
		if (pool == null) {
			System.out.println("createPool");
			OrderedProperties logonProperties;
			try {
				
                FileInputStream fileIn = new FileInputStream("c:\logon.properties");
	
       //>>>previous> logonProperties = OrderedProperties.load("/logon.properties");
				
	
      //error here			 	

logonProperties=OrderedProperties.load(fileIn);
				
	JCO.addClientPool(connectionPool,5,logonProperties);
				
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
				System.err.println("logon:" +e);
			}
		       
		
		}
		mRepository = new JCO.Repository("ElectcomsRepository", connectionPool);
		System.out.println("mRepository " + mRepository);
	}

i dun understand your obj.load(fileIn);

your load method is void , instead i need to have a Properties to put it in

addClient(String,int,Properties);

Hi,

Replace your code with the following code.

// java.io.InputStream is =OrderedProperties.class.getResourceAsStream(name);

java.io.InputStream is =new FileInputStream(name);
