Re: JWS on Linux
John, Many thanks for replying to my original enquiry, I have since managed to get the server working, however I am still having problems connecting and adding an oracle servlet (using oracle 8.0.5) and adding/registering it to the javaserver. I think mysql databases work fine however I am attempting to use an oracle database. If anyone can help regarding the correct protocols to use and syntax for connecting oracle and an http javawebserver it would be great so that I can use a homepage to query my database.

Calling Same Native method more than once.
Hi all, Thanks for helping me in interfacing C with Java.I am facing a problem in executing my program(java) which calls a 'C' function. I am calling 'C' native method for every 10 secs in my 'java' program , but after first loop, my program(java) exits by giving SIGSEV 11* Segmentation violation . How to call same native method for more than one time ?. Thanks in advance, -- Nagaraj S.B.

Re: Calling Same Native method more than once.
I don't think there is any limitations on the number of calls of C routine. I call my C routine from Java thousand times without any problem. Look for something else - memory problem of threads. Do you call your routine from the main tread or you created separate one?

Re: Calling Same Native method more than once.
I have call the same native method from several threads under several different JDK's and have not had any such problems. I am not sure that Blackdown's 1.2 with native threads is in the list of JDK's I have used. Not, that I think the JDK is the problem I just do not want to imply that I have tested this scenario.

File or class transfer over tcpip
I am in the mist of developing an RMI Update utility for clients. Like
most updaters they would download a small 30k(+-) java application that
would talk to an RMI server and decide what files (.class) the client
needed. It works like a charm but, the typical but word my classes when
used by the JVM either through security exceptions or are unreadable. To
transfer the class file we are using the following:
NOTE: FileDataInterface is just an RemoteInterface that returns the
byte array to the client so they may store it in the proper place with the
given name.
public FileDataInterface getFileData(String packageKey) throws
RemoteException
{
if (m_FileList.containsKey((String)packageKey))
{
FileInfo fi = (FileInfo)m_FileList.get((String)packageKey);
String loc = fi.getLocation();
System.out.println("Getting file: " + loc);
try
{
DataInputStream di = new DataInputStream(new
FileInputStream(new File(loc)));
int avail = di.available();
System.out.println("Available: " + avail);
byte[] data = new byte[avail];
di.readFully(data);
FileData fd = new FileData(data);
return fd;
}
catch (FileNotFoundException fn)
{
System.out.println("FileNotFoundException: " + fn);
return null;
}
catch (IOException io)
{
System.out.println("IOException: " + io);
return null;
}
}
else
{
return null;
}
}
Is there another way to transfer class files or other files for that
matter across tcpip that will not modify the file layout, just taking raw
data from one maching to another. Can anyone see what I might be doing
wrong.
-Bob

I'm afraid it's an RTFM. available() tells you how many bytes can be read
without blocking. This is NOT necessarily the size of the file. You're
probably sending the first 1k of each file to your clients. The class
file will then of course fail during loading.
Just a guess,
dstn.
PS - I wrote an app that does something like this (transferring file via
RMI), and I would suggest that you be extremely careful about path
separator characters.
