HTTP communication

[Maxim Neshcheret]

I have a problem with my java application related to HTTP communication.

Application description:

1.  Client – server. Server is running in servlet container. We use Tomcat.

Client use java HTTP library to communicate with the server.

2.  When client establish connection to the server it sends GET request 
(keepalive) and server creates AsyncContext for the client with 10 days timeout.

3.  After connection established server periodically sends data to the 
client using AsyncContext and on the client side there is special thread which 
reads and processes the data.

Client reading thread example:

private class GetRunnable implements Runnable {

   private final HttpURLConnection httpConn;
   private final MyConnection myConn;

   public GetRunnable(final MyConnection myConn) throws IOException, 
AppException {
 this.myConn = myConn;
 final String jSession = myConn.getJSession();
 httpConn = openHttpUrlConnection(false, httpPostTimeout, jSession);
 httpConn.connect();
 final int respCode = httpConn.getResponseCode();
 if (respCode != HttpURLConnection.HTTP_OK) {
String info = "Incorrect response from server, 
responseCode:" + respCode + ", message:" + httpConn.getResponseMessage();
log.error(info);
throw new AppException(info);
 } else {
log.trace("GET connected");
 }
   }

   @Override
   public void run() {
 try (final BufferedReader reader = new BufferedReader(new 
InputStreamReader(httpConn.getInputStream(), "UTF-8")) ) {
log.info("doGet STARTED");
final Thread t = Thread.currentThread();
while (!t.isInterrupted()) {
   log.trace("before readline");
   final String line = reader.readLine();
   log.trace("after readline: [" + line + "]");

   //INFO: DATA PROCESSING HERE
}
 } catch (IOException e) {
log.error("Error while doGet");
 } catch (Throwable e) {
log.debug("doGet STOPED...");
log.error("Error while read input msg, do logoff", e);
logoff();
throw e;
 }
 log.debug("doGet STOPED...");
 myCallback.onGetClose(myConn, connInfo);
   }
}

Server side code to push data looks like this:

protected int sendMsgs(final MyConnection myConn, final String info) {

   int res;
   try {
 final AsyncContext lAc = _ac;
 final ServletRequest req = lAc.getRequest();
 if (!req.isAsyncStarted()) {
log.debug("AsyncStarted=false on begin, uid:" + uid + ", 
sid:" + sid);
return -1;
 }

 final ServletResponse res = lAc.getResponse();
 ServletOutputStream  os = null;
 final String text = getData(myConn);

 if (os == null)
os = res.getOutputStream();

 write2stream(os, text, 0x4000);
 os.println();

 if (os != null)
os.flush();
} catch(IOException ex) {
 log.error("Notify failed");
} catch (InterruptedException e) {
 log.error("Notify failed");
 Thread.currentThread().interrupt();
 } catch (Throwable e) {
log.error("Notify failed");
logoff(true);
 }

return res;
}

public static void write2stream(final OutputStream outputStream, final String 
text, int bufferSize) throws IOException {
 final CharsetEncoder encoder = 
getHttpEncodingCharset().newEncoder();

 final int fullLen = text.length();
 final int byteBufferSize = Math.min(bufferSize, fullLen);

 final int en = (int)(byteBufferSize * 
(double)encoder.maxBytesPerChar());
 final byte[] byteArray = new byte[en];

  final ByteBuffer byteBuffer = ByteBuffer.wrap(byteArray);
  final CharBuffer charBuffer = CharBuffer.wrap(text);
 for(int pos=0, len=byteBufferSize;
   pos < fullLen;
   pos=len, len=Math.min(pos+byteBufferSize, fullLen)) {

  try {
final CharBuffer window = charBuffer.subSequence(pos, len);

   CoderResult res = encoder.encode(window, byteBuffer, 
true);

if (!res.isUnderflow())
res.throwException();

res = encoder.flush(byteBuffer);

if (!res.isUnderflow())
res.throwException();

} catch (final CharacterCodingException x) {
throw new Error(x);
   

NullPointerException when using NIO connector

[João Sávio]

Hello guys

I'm using Tomcat 7.0.53 and I've changed it to use the NIO connector
recently. So, the following error start appearing on the logs (few per day)

Jan 25, 2016 3:10:16 PM org.apache.tomcat.util.net.NioEndpoint processSocket
SEVERE: Error allocating socket processor
java.lang.NullPointerException


Any guesses? Is it a bug already fixed on newest versions?

Thanks
João

Those commands mean you compile source code of those libraries. So you 
have to either download source code as zip archives and extract them or 
check it out from version control. You probably need more C development 
tools like a compiler.


Instead of compiling it yourself you can try to install a precompiled 
version from your linux disros repositories:

yum install apr tomcat-native

If you use a recent version of tomcat it might happen that precompiled 
libraries are outdated.

If you just want to avoid that log message you can disable apr connector 
AprLifecycleListener in server.xml.

following mod_jk binaries are available :

However, I am looking for a "x86_64-httpd-2.2.x" version. (Windows, Apache 2.2 
64-bit).
Any idea where I could find ditto ?

(In a pinch, we could de-install the Apache 64-bit and re-install a 32-bit version, but 
we'd rather not have to do that)


Thanks for any info

Re: Installing APR based Apache Tomcat Native Library

[Yuval Schwartz]

Thank you Christoph,

I installed a compiled version from the distros on my production servers
and I installed the binary version from
http://tomcat.apache.org/download-native.cgi
on my development server.

A slight problem is that when I install from the distros I don't have
control of the version and therefore there is a slight mismatch between my
development and production environments (development version: Apache Tomcat
Native Library 1.1.34 using APR 1.5.1, production version: Apache Tomcat
Native Library 1.1.33 using APR 1.5.1)


Thank you

Tomcat 8.0.30 silently transforms 302 into 404

[Thomas Scheffler]

Hi,

it seems that Tomcat 8.0.30 silently transforms a redirect response into 
a not-found response.


https://bz.apache.org/bugzilla/show_bug.cgi?id=56917 introduces redirect 
to relative URLs.


Before 8.0.30 a redirect URL string was simply returned to the client. 
Now it has to be a valid URI (not URL) for the response to succeed.
If URI.create() fails, no error message is given or exception is thrown. 
Tomcat just sets the response code to 404.


This behavior was introduced in revision 1717256. I appreciate stricter 
rules in this point, but please consider throwing a RuntimeException 
(best option) or at least log the error somewhere.


kind regards,

Thomas

FW: Re: tomcat 6.0.41 heap size issue

[Guo, Denny]

Hi All,

Looking for help on tomcat heap size issue.

We are see below GC activity before tomcat reports the heap size error. Please 
see below message. However, we assign -Xmx=24G to the heap size, why tomcat 
reports error even not reach 20G heap size usage ?  Can someone please help. 
How the tomcat decides how much memory allocate to young/old generation?

We are running tomcat 6.0.41 on red hat linux as per our vendor.

Thanks,
Denny

Re: FW: Re: tomcat 6.0.41 heap size issue

[kidambi madhu]

Ok What's the size of the war file you have deployed to Tomcat?

I suspect the problem is with PermSize (The class loading part of JVM) than
Heap though the error points out Java Heap.

Pls set the PermSize with -XX:PermSize and -XX:MaxPermSize options and test.

Thanks,
Madhu

Hi.

On the page

the following mod_jk binaries are available :

However, I am looking for a "x86_64-httpd-2.2.x" version. (Windows, Apache
2.2 64-bit).
Any idea where I could find ditto ?

(In a pinch, we could de-install the Apache 64-bit and re-install a 32-bit
version, but we'd rather not have to do that)



You may try here:
http://www.apachelounge.com/download/win64/

The Tomcat committers no longer provide binaries for mod_jk (the dev
environment was lost).
E.g. 1.2.41 was a sources-only release.

It is known that apachelounge.com builds mod_jk for their builds of httpd.




I think that I hit the send button too quickly before..

I wanted to say thanks,
I did indeed find what I was looking for on apachelounge.

You may try here:
http://www.apachelounge.com/download/win64/

The Tomcat committers no longer provide binaries for mod_jk (the dev
environment was lost).
E.g. 1.2.41 was a sources-only release.

It is known that apachelounge.com builds mod_jk for their builds of httpd.

Hi.

On the page
http://apache.lauf-forum.at/tomcat/tomcat-connectors/jk/binaries/windows/,
the following mod_jk binaries are available :

tomcat-connectors-1.2.40-windows-i386-httpd-2.0.x.zip   2014-04-14 21:40
130K  ZIP compressed archive

tomcat-connectors-1.2.40-windows-x86_64-iis.zip 2014-04-14 21:40
216K  ZIP compressed archive

However, I am looking for a "x86_64-httpd-2.2.x" version. (Windows, Apache
2.2 64-bit).
Any idea where I could find ditto ?

(In a pinch, we could de-install the Apache 64-bit and re-install a 32-bit
version, but we'd rather not have to do that)

Ok, understood.
