I started jetty in nonstop server on port 18095 and it was running fine, few days later suddenly noticed it consumes more CPU, when I check the log noticed the following log writing continiously

Exception clearing file manager: java.io.IOException: Bad file number

I see the following exception when closing the environment. Not reproducible easily, happens only with production user's data occasionally. Any ideas on what causes this and what can be done to resolve it?

Thanks for the pointers.
We are running on Solaris.
I located a narrow window in our code where another thread from the same process was permitted to close the environment when a close is already in progress. Will plug that window.

Forwarding/Redirecting throws java.io.FileNotFoundException but file exists

http://www.mydomain.com/common/handler.jsp:
<jsp:forward page="/common/error_page.jsp" />This throws a java.io.FileNotFoundException:
java.io.FileNotFoundException: resource not found: /common/error_page.jspHowever, I can go to http://www.mydomain.com/common/error_page.jsp and verify that it does indeed exist.
Why would it throw a FileNotFoundException if not only does the forwarding page exist but exists within the exact same web module?
I checked ibm-web-ext.xml for the "common" web module to notice that fileServingEnabled="true".
Any ideas why this is happening?

A forward is relative to the context root - not the server's root.
So assuming you have a web application called "common", and "common" is its context name, then "/" would already refer to http://www.mydomain.com/common/
Thus your forward should just be to "/handler.jsp"
A redirect is slightly different, because it is resolved on the client, not the server.
So if you had a web context "myContext"
You access it with http://www.mydomain.com/myContext
<jsp:forward page="/mypage.jsp"> (or getRequestDispatcher("/mypage.jsp")) would refer you to http://www.mydomain.com/myContext/mypage.jsp.
to achieve the same destination with a redirect you would have to have
response.sendRedirect("/myContext/mypage.jsp");

Upload-Szenario - WDRuntimeException Bad file descriptor

Hi All,
i'm using the Adobe Document Services on a NW04, ADS SP 19, NWDS 2.0.19 with IE 6.0.2900 SP2.
If i use the Upload-UI-Element to show a PDF i got the error: Bad file descriptor !!
The PDF to upload is not corrupt, an i can open it with Acrobat Reader or the Tutorial (Download-Upload-Szenario) - Example.
I had a binary Value-Attribute mapped as Data-Element of the UploadUI-Element. Read the Context-Value-Attribute to the controller context element and the Interactive Form Element had the reference to the attribute as pdfsource. The same code as the tutorial.
What's wrong ?
I didn't find anything about the error !
Thanks for help.

Two things I think helped to solve this
PROPAGATE_EXCEPTIONS = True
in config.py and I removed threading from my vassal ini file the ending uwsgi files looked like this:
/etc/uwsgi/emperor.ini:
[uwsgi]
emperor = /etc/uwsgi/vassals
master = true
plugins = python2
uid = http
gid = http
[/etc/uwsgi/vassals/test.ini:
[uwsgi]
chdir = /srv/http/test_dir/src
wsgi-file = run.py
callable = app
processes = 4
stats = 127.0.0.1:9191
max-requests = 5000
enable-threads = true
vacuum = true
thunder-lock = true
socket = /run/uwsgi/test-sock.sock
chmod-socket = 664
harakiri = 60
logto = /var/log/uwsgi/test.log
Not sure on the
PROPAGATE_EXCEPTIONS = True
but removing the threads option in test.ini and making sure there was a master option in emperor.ini seemed to have solved the issue of sql being tossed around to different treads, or at least it complaining about it and crashing the site out, either or.
Also don't use the uwsgi from this distribution, get it from pip, the distros are broken.

Hello Naveen,
I am experiencing exactly the same error message when trying to create a database through dbca(RH LInux). The assistant guides me through the process of locating the directories and naming the database but when I validate all choices and try to finish up the process I get the following error and dbca seem to enter some kind of loop. However nothing of the database is created. Did you manage to pass that stage if yes could you let me know how you went throught it. I am stuck to that point and no script was generated to manually create the DB.
If anyone else has a clue your advices are much awaited thanks in advance.

Bad file number - comes when i upload the file

While i tried to upload the file more 300 kb (any file type)to 2 apache server using nfsmount (nfsmnt-apache 1 and nfsmnt2 -apache 2) through weblogic 9.2 (it is running in linux), i got the following exception, but less 200kb file i can upload the file (any type) to both apache server.
java.io.IOException: Bad file number at java.io.FileInputStream.readBytes(Native Method) at java.io.FileInputStream.read(FileInputStream.java:177) at
anybody known this prob, pls help me

Suggestion: read [the documentation|http://commons.apache.org/fileupload/using.html] for it.
By default it will store files in memory up to about 10k. Larger than that will be written to disk.
If you are really worried about memory, perhaps you should take a look at the [streaming API|http://commons.apache.org/fileupload/streaming.html]
How large are the files being uploaded?
How many users are we talking about?

SEVERE: java.io.FileNotFoundException: ./config/jps-config.xml (No such file or directory)

I am installing OIM/OAM in a cluster configuration using release 11.1.1.7.
I looked at the EDG here:

Exception: java.lang.UnsupportedClassVersionError: Bad version number in .class file

Hi, thank you for the reply. However, java is definitely enabled on my computer, on all my browsers. In fact, if I go to the SUN website and run the java test, I get that all is OK.
I think it may have something to do with the .class (maybe in .jar-file) compiled with a higher version of java than the virtual machine trying to run it.
The example I found (google search) is .class-file that is compiled with JDK 6 and I am trying to run it with 1.4 JVM.
There is some software error going on somewhere... but I do not know enough to fix it.
Many thanks for all your help

Java.io.FileNotFoundException (Too many file open)

Hi,
I have an application wherein I have to open an XMl file, make amends to it and then write it back. It is possible that the same XML file be opened more than once. After processing lots of XMl files I get the following error:

     else

return response;
}Here also I am not explicitely opening any handle. parse method should close the file after creating a DOM tree.
I would appreciate if someone could give me some directions as to what might be wrong.

I'm finding that builder.parse(File) doesn't close the file. I now create a FileInputStream from the File and make sure I close it myself in a finally{} block.

Hi,
Yes, i was able to fix the issue. The template associated with the bursting process needs to be in a single table. I had 2 separate tables due to which the program was completing with error. When i placed both those tables in a single table the issue was resolved.

Getting java.io.FileNotFoundException: Too many open files

I have search for different strings in a file again and again. I am using following code:
try
               fileReaderObject = new BufferedReader(new FileReader(fileObject));
               String inputLine;
               while ((inputLine = fileReaderObject.readLine()) != null)
                    if (zipCode.equalsIgnoreCase(inputLine.split("\t")[0]))
                         s = inputLine;
                         fileReaderObject.close();
                         return s;
               fileReaderObject.close();
          catch (Exception e)
               Utils.writeMessage(e.toString());
               e.printStackTrace();
          }But getting java.io.FileNotFoundException:file/emp_info (Too many open files)
1. Whats the main reason of this exception and how can it be removed.
2. Is there any way to move the pointer to the start of the file. I tried reset() but its seems to have some problem.

A hint: your fileReaderObject is not closed if an exception occurs.
Lacking desctructors, the Java-ish way is to close in a finally clause.

Java.io.FileNotFoundException: d:/tmp/dummylog.txt (No such file or directo

We are using WL 8.1 SP4 on RH Linux 7.2 and have this (non-critical, but annoying) error during runtime. When it hits, the same error gets printed out like a 100 times.
This one is really blowing my mind. I have searched through all our files (including binaries) for "dummylog" and "dummylog.txt" and can't find anything referring to this log file, so where the heck could it be coming from?
This error happens at least each time a user logs in to our application:

From the stacktrace,
com.takecargo.utils.SimpleDebugger.write(SimpleDebugger.java:27)
this seems to try to write the file. Do you know what that is? Also create the file with that name manually and see if it works.
Thanks,
