Tomcat hangs on startup
I'm running Tomcat 6.0.18 on Debian Linux (Lenny). Tomcat is configured to start automatically through the init process, but it hangs using 95+% of the CPU and won't respond to /etc/init.d/tomcat stop. I have to kill the process. I've tried manually starting it as root with /etc/init.d/tomcat start and with /opt/tomcat/bin/startup.sh but the same thing happens. The last entry in catalina.date.log in all cases is INFO: Overriding property struts.configuration.xml.reload old value false new value:true However, if I cd to the directory /op/tomcat/bin and run ./startup.sh from there Tomcat starts normally.

Re: Create FileInputStream in servlet from remote file with accentuated character name
Christopher Schultz wrote: ... What is the source of that file name? Is it hard-coded into your Java code? If so, how? Did you just type fichié.txt into your .java file, or did you use \uxyz syntax to specify the UNICODE character you intended? If you are reading the filename from a remote client, then all the request URI encodings and all that stuff are definitely relevant (ion spite of my previous statements to the contrary). ... Honestly, I think the above should not be a problem. ... Christopher, what I am trying to say is that such matters are horrible, because *everything* matters. One cannot even be sure that the logfile message, as seen by the user and as pasted in the email to the list, and as further seen by the reader on this list, is really how the message is physically stored in the logfile. That's because in-between, there can be umpteen layers of decoding/encoding which can make matters really confusing. (Even the encoding used by the process which writes the logfile may matter, because fichié.txt may already have been re-encoded right there.) Your note about making sure, in the source code of the program, that the filename is really made out of the bytes which the OP thinks it is made of, is a good example. If, to create this program source, one uses an editor which is set to save its files in the iso-latin-1 charset, then fichié.txt will be saved, in the program source, as a string of 10 bytes. Conversely, if one uses an editor set to save its files in Unicode/UTF-8, then this same string will be saved as 11 bytes (the é occupying 2 bytes). Then comes the compiler.. I don't know how a Java compiler handles source code respectively saved as an iso-8859-1 encoded file, or as a UTF-8 encoded file. How does it tell the difference ? does it make assumptions based on the locale it is running under ? About the creation and subsequent finding of a file : Generally-speaking, filesystems are encoding agnostic, in the precise sense that : - if on a given platform and with a given programming language, you arrange for a string variable S to contain a precise series of bytes (for example, the UTF-8 encoding of the string fichié.txt, 11 bytes long) - if you then use that variable as the name of a file which you create on disk - then no matter where this file directory ultimately resides, the name of the file in it will generally be these same exact 11 bytes. - if you then, from the same platform and using the same programming languages, use this same variable A as the name of a file which you try to open, it will work. However, as soon as you deviate from the strict case above, what looks to you like fichié.txt /may/ not be the same series of bytes anymore, and that's where the problems start. How the filename will look like is however another matter, depending on what you use to display it and from where you do it. In the case of Sylvie (and I am talking here about the final issue she is trying to handle, not just about the test case) - presumably, some (other) users and/or applications, running on some (other) platform and using some (other) tools, are creating files inside of a Windows host's directory. One item of interest here would be to know how these files are created, and if that process is consistent (meaning, are these files always created by the same programs, running always on the same platform, using the same encoding etc..). That is to make sure that when a file named fichié.txt is created there by whatever, it will always be created the same way, with a name of either 10 or 11 bytes (it does not matter which, just that it be consistent). - then, some program created by Sylvie, has to access that directory, and pick up files from there. So this program may have to know how a filename fichié.txt will be encoded in that directory (either as 10 or 11 bytes). It also does not matter which, as long as Sylvie's program has a way to consistently spell this name correctly. The problem is generally unsolvable, if the original entry in the directory can be created in several ways, because there are multiple agents capable of creating it, and these agents use inconsistent encodings. The issue can be simpler, if Sylvie's program just opens the directory, reads the filenames that it finds there (whatever their encoding is), into some variable, and then just uses this variable as the filename to open the file and that's it. But if, in Sylvie's program, the filename itself has to be compared to some pre-defined other string stored in the program, and some action taken or not whether it is considered equal or not, then there may be a problem. Yet another aspect to consider, is whether Sylvie is really testing the right thing. For instance, when Sylvie runs her Java test program, she does this from inside a Linux session, which is set for a specific locale. However, the Tomcat server may well be started under a different

What I want is to append app_context in the file name.
Thanks,

IIRC, there is no way to obtain the application context path as an

You should configure Log4j using its APIs, using a ServletContextListener.
Probably the best way is to load the log4j.properties file and
modify only the property that refers to the path of the file, then
configure Log4j.

You do not control these agents, nor the file names that they choose to put there. - your application, running (later) under Tomcat, is supposed to read these files and do something with them.

Eh.. well, yeah. :) Your note about making sure, in the source code of the program, that the filename is really made out of the bytes which the OP thinks it is made of, is a good example. If, to create this program source, one uses an editor which is set to save its files in the iso-latin-1 charset, then fichié.txt will be saved, in the program source, as a string of 10 bytes. Conversely, if one uses an editor set to save its files in Unicode/UTF-8, then this same string will be saved as 11 bytes (the é occupying 2 bytes). Then comes the compiler.. I don't know how a Java compiler handles source code respectively saved as an iso-8859-1 encoded file, or as a UTF-8 encoded file. How does it tell the difference ? does it make assumptions based on the locale it is running under ? javac is documented to use the platform default encoding (for /Java/), which may not be the default encoding of your editor. :( http://java.sun.com/javase/6/docs/technotes/tools/windows/javac.html Without any interference from me, my compiler chooses ANSI_X3.4-1968 which is roughly Latin-1, so any funny business in there like Thử nghiệm Tiếng Việt isn't going to fly. It's always best in Java source files to use something as close to ASCII as possible and use the \u encoding of any special UNICODE characters. The OP won't cough-up the source code, though, so we don't even know if this is a source code problem or an HTTP-request-parameter interpretation problem. One item of interest here would be to know how these files are created, and if that process is consistent (meaning, are these files always created by the same programs, running always on the same platform, using the same encoding etc..). That is to make sure that when a file named fichié.txt is created there by whatever, it will always be created the same way, with a name of either 10 or 11 bytes (it does not matter which, just that it be consistent). +1 The problem is generally unsolvable, if the original entry in the directory can be created in several ways, because there are multiple agents capable of creating it, and these agents use inconsistent encodings. Yup. Unless you read the directory entry from the filesystem and guess at the right file (ha!), you might not get the one you want. However, the Tomcat server may well be started under a different locale setting, and this may have an impact as to how each one of them looks at the filename fichié.txt. Unfortunately, the Java API says nothing about the encoding used to read and write filenames. :( Then of course, after the above trivial matter of the filename is resolved, one may have to tackle the matter of how the file contents are encoded. At least the programmer has some measure of control over that. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkq45ewACgkQ9CaO5/Lv0PAVsQCgt9YnaEBJhRatVGgsUWjkmLlC 9yEAn03E+uM5bslLUZ1/sC4y3/3z1y0u =pCP2 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

André, Thanks to you, my testcase is now running without any exception.

Let me see if I understand correctly your basic issue (not the test program, but the real application you need to create). - miscellaneous agents create files, on some media, which is later connected to a Windows system and becomes a shared directory. You do not control these agents, nor the file names that they choose to put there. - your application, running (later) under Tomcat, is supposed to read these files and do something with them. I suppose that you do not know in advance, what the names of these files will be, and you just have to take what is there. Is that correct ? You perfectly undestood requirements of my real application. I know that I will expect others wonderful problems :-) Thank you again for your great help.

RE: Log4j
I had a similar problem with log4j.
We host our webapp for various customers, an instance (host) per
customer, therefore the same code for each customer. I tried sharing
log4j.jar in shared/lib, but found all customer loading into the same
log file - very confusing.
My solution was to put log4j.jar in WEB-INF/lib of each instance, along
with individual log4j.properties files and setting different file paths
in the properties files. Only solution I could find.

What should be the configuration in log4j.properties?
I am currently using
log4j.appender.xml.file=${catalina.base}/output/logs/service.log
What I want is to append app_context in the file name.
IIRC, there is no way to obtain the application context path as an
environment variable.
You should configure Log4j using its APIs, using a
ServletContextListener.
Probably the best way is to load the log4j.properties file and
modify only the property that refers to the path of the file, then
configure Log4j.

I wonder if Java uses the file.encoding system property (which is set by
the portion of $LC_ALL after the .) to convert bytes returned from the
filesystem into filenames and vice versa.
Yeah, that appears to be the case:
import java.io.*;
public class FileEncodingTest
{
public static void main(String[] args)
throws Exception
{
System.out.println(Using file.encoding= +
System.getProperty(file.encoding));
File file = new File(\u03c0); // That's a lowercase Greek pi
Writer out = new FileWriter(file);
out.write(A test file\n);
out.close();
file = new File(.);
File[] files = file.listFiles();
for(int i=0; ifiles.length; ++i)
{
file = files[i];
System.out.print(file.getName());
System.out.print(\tunicode: );
byte[] bytes =
file.getName().getBytes(UnicodeBigUnmarked); // Trust me

if(1 == hex.length())
System.out.print(0);
System.out.print(hex);
System.out.print( );
}
System.out.println();
}
}
}
Output on my system:

? unicode: 03 c0 (/this correctly emitted the glyph for pi/)
Then, for good measure:
$ java FileEncodingTest

FileEncodingTest.class unicode: 00 46 00 69 00 6c 00 65 00 45 00 6e 00

61 00 76 00 61
? unicode: 00 3f
?? unicode: ff fd ff fd (/this did not/)
So, when running in ANSI_X3.4-1968-mode, Java takes the codepoint for pi
(0x03c0) and destroys it (note the two-character filename where the
first byte is NUL). I'm not really even sure how it does that... I'd
have expected some broken sign-extension or something but I have no idea
how 0x03c0 becomes 0x003f.
When running in UTF-8 mode, the correct code point is used for the
filename and read-back correctly using listFiles.
When running again in ANSI mode, the original (incorrect) filename is
(predictably) read- back in the same way as the original, but the
filename with the correct code point is again garbled (0x03c0 -
0xfffdfffd).
Somebody needs to write a virus that just converts everything to UTF-8
so we can be done with it.

Hi, We have a web application that runs on Tomcat 6x. We want to deploy this application on a symbol MC 3090 device running windows CE as the OS. Would it be possible to deploy Tomcat 6x on Windows CE and run our application on that? Thanks, Ajay

At least the programmer has some measure of control over that. Not if she doesn't know what they have been created with though.

- your application, running (later) under Tomcat, is supposed to read
these files and do something with them.
I suppose that you do not know in advance, what the names of these
files will be, and you just have to take what is there. Is that correct ?
You perfectly undestood requirements of my real application.
I know that I will expect others wonderful problems :-)
Ok, then we need Christopher's Java knowledge now.
Christopher, how does one, in Java, read a directory item by item ?
We need this kind of thing :
- open the directory
- while (variable fn = next directory item) {
- next if item is not a regular file
- open the file named fn
- do something to that file
- close the file
- delete the file ?
}
- close the directory
And (just to anticipate the next issue), Sylvie, does your program
actually need to read the content of the file and do something with that
content ?

Re: Deploying Tomcat on Windows CE
Could you give me a ballpark estimate of what it could cost and how long the development would take?

I wonder if Java uses the file.encoding system property (which is set by the portion of $LC_ALL after the .) to convert bytes returned from the filesystem into filenames and vice versa. Yeah, that appears to be the case: Christopher, your detailed analysis is impressive and undoubtedly accurate, but beyond what I can swallow right now in Java and after 2 glasses of Spanish wine. So let me ask a simple question : - a file named fichié.txt has been created in a directory, by a process that spoke iso-8859-1 (so the filename is 10 bytes long). - a Tomcat runs in a process whose locale is set to UTF-8, and an application inside this Tomcat reads the filename from the directory into a Java String variable S. What happens ? - does the application get an exception due to invalid encoding ? - if not, why not ? - if not, what is now the content, in bytes, of variable S ? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

It's probably better than having 2 pints of Belgian beer. Wow. So let me ask a simple question : - a file named fichié.txt has been created in a directory, by a process that spoke iso-8859-1 (so the filename is 10 bytes long). Ok. - a Tomcat runs in a process whose locale is set to UTF-8, and an application inside this Tomcat reads the filename from the directory into a Java String variable S. What happens ? - does the application get an exception due to invalid encoding ? No. The results of my other test suggest that you basically just get garbage characters in the filename. - if not, why not ? Good question. Maybe the JVM authors decided that garbage characters were better than an inaccessible file (and I tend to agree with that trade-off). - if not, what is now the content, in bytes, of variable S ? Heh. Beats me. I couldn't understand how the UTF-8 filename had been mangled when in ANSI mode, so I'm not sure if such mangling is reversible. I wonder if you could re-encode the filename something like this: String encoding = System.getProperty(file.encoding); String filename = file.getName(); // gets you junk String recoded = new String(filename.getBytes(encoding), UTF-8); Of course, this only works if: 1. the file was originally written in UTF-8 mode 2. The ANSI mangling that has occurred is reversible using the above method (duh) If you have some suspicion as to the encoding used to encode the filename in the first place, you could re-code the filename several times and attempt a match (using String.equals). Better yet, you could re-code the filename you /think/ you have into a String and then use that to check against the filesystem. I dunno. This is pretty ugly. Again, setting everything to UTF-8 dramatically reduces headaches in these areas. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkq5L04ACgkQ9CaO5/Lv0PAlGQCdEjzO/3Ikf1ooQDVmkpzOiLl1 j0IAn1NiU8tbcdMGDra6thzvPFYml1m3 =yOp/ -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
