Re: [ptp-dev] Questions about remote support
Great thanks. I've been trying to work out the best way to do this for some time. I'll take a look tomorrow.

Hi Greg,
I got another problem on ptp remote. I cannot find "RSE" in combo box of "remote service provider" in Resource Manager Wizard. I found there is an error occurred while initializing rse service. Please see RSEServices file and line 86. This line of code always returns false. Any idea?
I commented that line and tried to connect to remote server. I can connect to the remote server, but I cannot connect to orte proxy. Please see the following message:
kxc565@ac~ > /home/565/kxc565/workspace-ptp/ org.eclipse.ptp.linux.ia64/bin/ptp_orte_proxy --proxy=tcp -- host=localhost.localdomain --port=53881 ;exit 
proxy connection failed
In linux, method InetAddress.getLocalHost().getCanonicalHostName() will return localhost.localdomain, but it gets the correct addrss at Mac. I provided a method as below that can be avoid the incorrect host address problem on linux. 

   public String getLocalAddress() throws IOException {
String addr = InetAddress.getLocalHost().getCanonicalHostName (); 
       if (addr.endsWith(".in-addr.arpa")) {
           addr = InetAddress.getLocalHost().getHostAddress();
       }
       if (addr.startsWith("localhost")) {
Enumeration<NetworkInterface> netInterfaces = NetworkInterface.getNetworkInterfaces(); 
           while (netInterfaces.hasMoreElements()) {
NetworkInterface ni = (NetworkInterface) netInterfaces.nextElement(); Enumeration<InetAddress> alladdr = ni.getInetAddresses(); 
               while (alladdr.hasMoreElements()) {
InetAddress ip = (InetAddress)alladdr.nextElement (); if (!ip.isSiteLocalAddress() && ! ip.isLoopbackAddress() && ip.getHostAddress().indexOf(":") == -1) { 
                       return ip.getCanonicalHostName();
                   }
               }
           }                  }
       return addr;
   }

I have it working now. I was getting a message about being unable to instantiate factory in the error log. 

I will look at using IPath objects to validate path names

I just updated from head a few minutes ago and now I'm getting a null pointer exception (see bottom of this email) when I try to create a new resource manager. This happens when I open the resource manager wizard, click PE from the list and click next. This worked correctly this morning.
If I updated while you were in the middle of commits, that's fine, just 
let me know to try again later.
Can you check the error log to see if there is any message like 'Failed to instantiate factory...'? Also, make sure you updated the org.eclipse.ptp.remote.rse plugin as well.
Also, the way my parallel tab works, I have a text entry field with a ModifyListener registered, and an accompanying Text field that gets filled in with a path name. This gets filled in either by the user typing in a path name or by my code as a result of the user selecting a file from the file selector, in which case I get the IPath object returned by calling browseFile, call toString() on that object and then fill in the text field 
with that value.

I don't attempt to validate the pathname until the ModifyListener
registered on the text field gets called, which occurs either when the user types in the field or when my code fills in the field using the pathname obtained from the IPath object. If the user has typed in a field, I don't see any way to validate that pathname, since I only know the pathname and the remote connection at that point (I don't have an IPath object). If I do have an IPath object, because the user clicked the 
browse button, then is the intent I call getResource() to get the
associated IRemoteResource, then validate using that object?
Yes. I'd like to see if we can use IPath objects rather than Strings as you get an extra level of validation. You can do something like this: 

                 IPath path = new Path(textfield);
                 if (!path.isValidPath()) {
                                 // invalid
                 }
IRemoteResource res = fileMgr.getResource(path, monitor); 
                 if (!res.fetchInfo().exists()) {
                                 // invalid
                 }

Let me know if that seems ok.

Greg
