Connection aborted by peer: socket write error! Please Help me!

I'm tring to put a file in a webdav folder in my project. For experience
I read a file from disk. If I do it in a single project, in a test
class, everithing goes well. 
But I wan't to do do it in a Servlet environment. Using ServletServer
that comes with jBuilder with the same exact code I get an exception.
I've tried also with Jrun, TomCat and the same happens.


Code and Exception fallows:
	  
InputStream input_stream = new FileInputStream(path+"/"+name);

...


	  File temp_file =  new File(temp_files_path, filename);
        BufferedReader in = new BufferedReader(new
InputStreamReader(input_stream));

        PrintWriter out = new PrintWriter(new BufferedWriter(new
FileWriter(temp_file)));
        while (in.ready())
          out.write(in.read());
        in.close();
        out.flush();
        out.close();
        try {
          method.sendData(temp_file);
          client.executeMethod(method);
          temp_file.delete();
        }
        catch(Exception ex){ex.printStackTrace();}
      }


This works fine standalone. But in servlet environment I get: 

java.net.SocketException: Connection aborted by peer: socket write error
	at java.net.SocketOutputStream.socketWrite(Native Method)
	at java.net.SocketOutputStream.write(SocketOutputStream.java:83)
	at
org.apache.commons.httpclient.RequestOutputStream.write(RequestOutputStr
eam.java:281)
	at
org.apache.commons.httpclient.methods.PutMethod.streamQuery(PutMethod.ja
va:255)
	at
org.apache.commons.httpclient.HttpClient.sendRequestBody(HttpClient.java
:1012)
	at
org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:5
07)
	...


I'm using Jakarta-Slide1.0.14 release in JDK1.3. . I've tried with
Crimson.jar+jaxp.jar, and with Xerces. 

Please help me, it's the only problem I have now. My project it's
finished and I need to solve this so I can graduate.

THANKS IN ADVANCE,

Regards 

Maik

RE: Connection aborted by peer: socket write error! Please Help me!

Posted by Miguel Carvalho <mc...@infopulse.pt>.
Well, since you have tested that simple example, I believe the problem
can be the server! I'm interacting with  MS IIS 5 (you mus't have missed
it in log files i've sent). It dosen't makes any sense those reconnects,
does it? I'm thinking about to try tomcat as server (you missunderstood
me, i used tomcat for test but only to run client servlet, the dav dirs
where in iis). do you know any howto install tomcat slide dav enabled?
i've tried it some months ago, but i had some troble to make it work
out. That's why i started using iis (bah).

Your TestServlet works for me...     :-)
I compiled your example using servlet.jar(2.2) and the latest cvs
version of httpclient. Looking at your example, I think you are using
Tomcat 4 as your webdav server ?

I did the following:
- changed following lines in your example
        System.out.println("temp_file path:   " +
temp_file.getAbsolutePath());
        System.out.println("temp_file length: " + temp_file.length());
        method.sendData(temp_file);
        client.setDebug(1000);
        client.executeMethod(method);
- used "http://localhost:8080/webdav" as http_url
- compiled TestServlet and put it in:
jakarta-tomcat-4.0-b7\webapps\examples\WEB-INF\classes
- put the following libraries in
jakarta-tomcat-4.0-b7\webapps\examples\WEB-INF\lib
    crimson.jar,jaxp.jar,commons-httpclient.jar,webdavlib.jar
    (both httpclient and webdavlib from slide cvs)
- run the servlet using:
http://localhost:8080/examples/servlet/TestServlet

The servlet works and gives "sucess!", on the log I get:
=============================================
Starting service Tomcat-Standalone
Apache Tomcat/4.0-b7
Starting service Tomcat-Apache
Apache Tomcat/4.0-b7
temp_file path:   D:\Temp\dontwork.exe
temp_file length: 625181

As you can see the client doesn't have to reopen the connection in my
case. What is your precise webdav server configuration ?

Hi! I've followed your suggestion Dirk. Debug mode didn't help me very
much. 

I separated the webdav put tests from all the remaining process so I can
trace package crossovers better. I've tried this 
With several combinations of need packages, and diferent webservers:

WebServers: ServletServer, Jrun, TomCat;
Servlet classes: jsdk.jar (2.0), Servlet.jar (2.2 and 2.3).

Xml: Xerces 1_3_1 versus jaxp.jar + crimson.jar (slide).

And I allways get the same results. I don't know if in Jrun case som
libraries may make interferience.

Please se the atacched files. The Test2.java first. It's the simple
example, that works fine TestServlet.java it's the same code in a
servlet. When putting small files (<100KB) it succeded but don't writes
anithyng. Putting larger files it gives the output in the log files.

Normally, running this code in a servlet environment shouldn't make a
difference.
There are 2 things you can do:
- check the file length after the close (temp_file.length())
- do a client.setDebug() before excutemethod

If this doesn't give an answer please send a complete servlet example that
gives the error.
