Read timed out in tomcat 4.1.31

2010-04-13 Thread Ningappa Koneri
Dear All,

I am getting a strange issue with an application deployed under tomcat 
4(4.1.31) that when I am trying to upload a file through browser along with the 
form data to the tomcat, file stream reader getting read timed out exception. 
In fileupload application I am using following code snippet.


MultipartParser parser = new MultipartParser((HttpServletRequest) request, 1805 
* 1024);
Part aPart;
while ((aPart = parser.readNextPart()) != null) {
if (aPart.isFile() == false) {
//read form data
} else if (aPart.isFile() == true) {
//read file
InputStream is = fPart.getInputStream();
bis = new BufferedInputStream(is);
byte[] buffer = new byte[1024 * 1024];
ByteArrayOutputStream baostream = new ByteArrayOutputStream();
int bytesRead = 0;
while ((bytesRead = bis.read(buffer)) != -1) { -- I am getting 
read timed out exception here

}
  }
}
}

One more thing what is observed that tomcat is taking 1025m virtual memory :(.

When I upload a file which is smaller in size It's getting succeeded.

Any idea ?

Regards,
Ningappa Koneri

RE: Tomcat 6 on RHEL3

2010-03-17 Thread Ningappa Koneri
Hi Gurkan,

I guess ur right, as tomcat is trying to deploy the applications it's taking 
lot of time because of compilation only I guess. One more thing is why home 
page is not coming? The http request bytes got stuck in recv queue of tomcat 
port. How to get rid of this situation ? can't v disable the compiling of jsp 
files at startup ?

It took abt 1328 seconds to startup the applications. Please help.

INFO: Server startup in 1327549 ms :(

Please look at logs file under directory logs. Maybe your JSP files are so
complicated and takes time while Tomcat compiles them on the first time.

  How long is hell lot?  The log message should tell you Tomcat started

 What's the spec of the machine on which you're running Tomcat?  How much
 heap and permspace have you allocated to the Java virtual machine in which
 Tomcat is running, and how much memory is it using?  (top will tell you how
 much memory it's using; it will be more than heap+permspace due to other
 operating system structures)

 Is the machine busy during all this time?  If so, what is the limiting
 factor - disk i/o, memory or CPU?  Run top to get an idea of CPU usage,
 vmstat (I use vmstat 5 until I have a better idea) to get an idea of disk
 i/o.

 How large is the war file?  If you unzip the war files (a war file is just
 a
 zip file with a different extension) on the same machine, how long does it
 take?

 Lots of questions, but we need more information to be able to answer.

RE: Question on allowLinking

2009-09-16 Thread Ningappa Koneri
Hi Pid,

Thanks for your reply and sorry for the delayed ack.

Basically we are creating a softlink to a directory (containing some sound 
files quite large in size) inside the webapps/project/jsp which we don't want 
to put directly under the application's project directory.

Is there any other settings I need to follow to instruct the tomcat not to 
delete the softlink contents ?

 Hi,
 I had a query regarding Tomcat 6.X. We are developing a web application which

 allowLinking property to true in the context.xml configuration. We have 
 observed that, upon un-deploying the .war file by deleting it from the 
 webapps directory, all the contents under the soft link get deleted as well! 
 We do not want this to happen, how do we ensure that only the soft link 
 inside the .war file gets deleted.

What are you linking, exactly, that needs to be inside the web
application directory?

If it's just images and styles, (for example), you should make them
available via a URL external to the application itself.  You could use a
multi-level war file to make the URLs appear inside the app's URL space.

  myapp.war   /myapp/
  myapp#scripts.war   /myapp/scripts/

Tomcat *will* remove the contents of the deployed directory when you
undeploy it, this is intentional - otherwise how could you update an
application?

 You probably have a memory leak in your application.

 The first thing to check thoroughly, and I do mean thoroughly, is that
 you are properly closing all database connections and related objects.
 Don't assume that you have done so - check every location in the code
 carefully.

 Depending on which OS  JVM version you have, (you didn't say - so we
 have to guess), there are tools you can use to examine the
 application's state and memory consumption.

 Google memory leak, jmap and thread dump

 Thanks in advance.

Enabling allowLinking in tomcat 6, deleting the soft link contents while undeploying!

2009-08-20 Thread Ningappa Koneri
Hi,

By Using  allowLinking=true in context.xml of tomcat 6, I am able to access 
soft links within the application project directory.
But the problem is when I undeploy the application by deleting only project.war 
file, tomcat is deleting all the contents inside the soft link along with that 
project directory, By this behavior it's causing the serious problem by 
deleting the valuable web content inside the soft link.

Please help me in this regard.
