Compiling Java code with Japanese characters

I have a Java code with some Japanese characters. My compiler doesn't recognise these characters and gives me error messages.
Please help me.

Obviously it's not the copmiler's fault. You need to fix your code.
Here is a link to the Java Language Specification.
The link is to section 3.8 - Identifiers.
It describes the acceptable naming:
http://java.sun.com/docs/books/jls/second_edition/html/lexical.doc.html#40625
Perhaps your editor is not saving the text file in an appropriate format.
What editor are you using?
Try vim http://www.vim.org
or SciTE http://www.scintilla.org/SciTE.html

EXCEPTION_ACCESS_VIOLATION (0xc0000005) on compiled Java code

I'm confronted with the following error of this code.
http://db-www.naist.jp/~makoto-y/tmp/Int2LongHash.java
The exception appears only when the system gets high-load.
Is there work-arounds?
I've tried also with jdk1.5.0_06, but the same error occurred.
Converting the inner class to a top-level class has no effects.

Issue with Japanese characters in files/filenames in terminal.

I recently downloaded a zip file with Japanese characters in the archive and in the files within the archive. The name of the archive is "【批量下载】パノプティコン労働歌第一等.zip"
The characters are properly displayed in firefox, chrome, and other applications, but in my terminal some of the characters appear corrupted. Screenshot: https://i.imgur.com/4R22m0D.png
Additionally, this leads to corruption of the files in the archive. When I try to extract the files, this is what happens:
% unzip 【批量下载】パノプティコン労働歌第一等.zip
Archive: 【批量下载】パノプティコン労働歌第一等.zip

extracting: +ii/flac/---- -instrumental-.flac bad CRC 569b6194 (should be adb5d5fe)
I'm not sure what could be the cause of this. I'm using uxterm with terminus as my main font and IPA gothic (a Japanese font) as my secondary font. I have a Japanese locale set up and have tried setting LANG=ja_JP.utf8 before, but the results never change.
Also, this issue isn't just with this file. This happens with nearly all archives that have Japanese characters associated with it.
Has anyone encountered this issue before or knows what might be wrong?

Maybe 7zip or another tool has workarounds for broken file names, you could try that.
Or you could try to go over the files in the zip archive one-by-one and write it to files out-1, out-2, ..., out-$n without concerning yourself with the file names. You could get file endings back via the mimetype.
This script might work:
#include <stdio.h>
#include <zip.h>
static const char *template = "./out-%04d.bin";
int main(int argc, char**argv)
int err = 0;
zip_t *arc = zip_open((const char*)argv[1], ZIP_RDONLY, &err);
if(arc == NULL)
printf("Failed to open ZIP, error %d\n", err);
return -1;
zip_int64_t n = zip_get_num_entries(arc, 0);
printf("%s: # of packed files: %d\n", argv[1], n);
for(int i = 0; i < n; i++)
zip_stat_t stat;
zip_stat_index(arc, i, ZIP_FL_UNCHANGED, &stat);
char buf[stat.size];
char oname[sizeof(template)];
zip_file_t *f = zip_fopen_index(arc, (zip_int64_t)i, ZIP_FL_UNCHANGED);
zip_fread(f, (void*)&buf[0], stat.size);
snprintf(&oname[0], sizeof(template), template, i);
FILE *of = fopen(oname, "wb");
fwrite(&buf[0], stat.size, 1, of);
printf("%s: %s => %lu bytes\n", argv[1], oname, stat.size);
zip_fclose(f);
fclose(of);
zip_close(arc);
return 0;
Compile with
gcc -std=gnu99 -O3 -o unzip unzip.c -lzip
and run as
./unzip $funnyzipfile
You should get template-named, numbered output files in the current directory.

Compiling Java Servlet with Depricated Methods

I have a problem of compiling Java servlets that contain depricated methods. If you compile against modern version of servlet.jar I see depricated methods error messages and if I use a very old servlet.jar it cannot find newer methods. What is is the best solution in this case?
Thank you,
Boris.

The best thing to do would be compile your code with the -depreciated option to find which methods have been depreciated and the refactor your code to remove them.
The next best thing is to ignore the messages (they are warnings not errors) and your code should still work

Error while running compiled java code

Hi
I have an evaluation license of the JDeveloper2.0 installed on my WindowsNT 4.0 workstation.
I seem to have a problem running my compiled jave code. After compiling the source code(.java file) when I try to run the same I get a message saying
"<FileName> not found in outpath classpath or sourcepath ".
What does this mean and how can I rectify it?
Regards
Sree

Your classpath tells Java run time where to look for the class files it needs. In JDeveloper the class path is set in your project properties. Select Project->Properties and check that the source and output paths correspond to your myprojects and myclasses directories.

Embedded Java code with bpelx:exec

When I embed Java code with bpelx:exec, I would like use classes packaged in a jar file. How do I ensure that the jar file is deployed with the suitcase? I tried adding the library to the JDeveloper project (right-click project, choose properties, libraries), but that did not work.

Although the tooling does not expose this functionality yet, the bpel packaging and bpelc command line tool support the ability to put a library in BPEL-INF/lib and using it in the exec activity. You can also put classes in BPEL-INF/classes. Please look at:
[ORACLE_HOME]\integration\orabpel\samples\references\JavaExec for more information.

How to check for a logic bomb in compiled java code ?

I have couple of security requirements.
1. How do I check for logic bomb in the compiled java code ?
2. Is there any way to monitor memory utilized by class when running inside a constructor ?

1. Let me see if you can define 'logic bomb', then maybe a answer can be supplied. If you simply mean malicious code, then in general you cannot. You can attempt to do the kinds of things that antivirus software does, like check for the existence of known malicious code and code patterns, but that won't work any better on Java than it does on anything else.
2. Google java profiling. Also, for something relatively simple, read about jconsole.

Collation issue with Japanese characters in Oracle8i

Hi,
I have japanese data in a varchar2 column in an Oracle8i instance which contains both single byte and multibyte Japanese characters. The encoding type of the instance is UTF-8.
I want to sort them in such a way that equivalent single byte and multibyte Japanese characters are treated as same. Also while selecting, if I specify the single byte characters in the where condition it should select both single and double byte characters and vice-versa.
The functionality I'm looking for is similar to the one which can be achieved by using Collator class in Java with FULL_DECOMPOSITION as decmposition mode.
Could anyone please let me know how can I do it ?
Thanks in advance.
Best Regards,
Sourav

Maybe 7zip or another tool has workarounds for broken file names, you could try that.
Or you could try to go over the files in the zip archive one-by-one and write it to files out-1, out-2, ..., out-$n without concerning yourself with the file names. You could get file endings back via the mimetype.
This script might work:
#include <stdio.h>
#include <zip.h>
static const char *template = "./out-%04d.bin";
int main(int argc, char**argv)
int err = 0;
zip_t *arc = zip_open((const char*)argv[1], ZIP_RDONLY, &err);
if(arc == NULL)
printf("Failed to open ZIP, error %d\n", err);
return -1;
zip_int64_t n = zip_get_num_entries(arc, 0);
printf("%s: # of packed files: %d\n", argv[1], n);
for(int i = 0; i < n; i++)
zip_stat_t stat;
zip_stat_index(arc, i, ZIP_FL_UNCHANGED, &stat);
char buf[stat.size];
char oname[sizeof(template)];
zip_file_t *f = zip_fopen_index(arc, (zip_int64_t)i, ZIP_FL_UNCHANGED);
zip_fread(f, (void*)&buf[0], stat.size);
snprintf(&oname[0], sizeof(template), template, i);
FILE *of = fopen(oname, "wb");
fwrite(&buf[0], stat.size, 1, of);
printf("%s: %s => %lu bytes\n", argv[1], oname, stat.size);
zip_fclose(f);
fclose(of);
zip_close(arc);
return 0;
Compile with
gcc -std=gnu99 -O3 -o unzip unzip.c -lzip
and run as
./unzip $funnyzipfile
You should get template-named, numbered output files in the current directory.

Oracle Report Server Issue with Japanese Characters

We are trying to setup a Oracle Report Server to print the Japanese characters in the PDF format.
We have separate Oracle Report servers for printing English, Chinese and Vietnamese characters in PDF formats using Oracle Reports in the production which are running properly with Unix AIX version 5.3. Now we have a requirement to print the Japanese characters. Hence we tried to setup the new server for the same and the configurations are done as same as Chinese/Vietnamese report servers. But we are not able to print the Japanese characters.
I am providing the details which we followed to configure this new server.
1.     We have modified the reports.sh to map the proper NLS_LANG (JAPANESE_AMERICA.UTF8) and other Admin folder settings.
2.     We have configured the new report server via OPMN admin.
3.     We have copied the arialuni.ttf to Printers folder and we have converted this same .ttf file in AFM format. This AFM file has been copied to $ORACLE_HOME/guicommon/gk/JP_Admin/AFM folder.
4.     We have modified the uifont.ali (JP_admin folder) file for font subsetting.
5.     We have put an entry in JP_admin/PPD/datap462.ppd as *Font ArialUnicodeMS: Standard "(Version 1.01)" Standard ROM
6.     We have modified the Tk2Motif.rgb (JP_admin folder) file for character set mapping (Tk2Motif*fontMapCs: iso8859-1=UTF8) as we have enabled this one for other report servers as well.
Environment Details:-
Unix AIX version : 5300-07-05-0831
Oracle Version : 10.1.0.4.2
NLS_LANG : JAPANESE_AMERICA.UTF8
Font Mapping : Font Sub Setting in uifont.ali
Font Used for Printing : arialuni.ttf (Font Name : Arial Unicode MS)
The error thrown in the rwEng trace (rwEng-0.trc) file is as below
[2011/9/7 8:11:4:488] Error 50103 (C Engine): 20:11:04 ERR REP-3000: Internal error starting Oracle Toolkit.
The error thrown when trying to execute the reports is…
REP-0177: Error while running in remote server
Engine rwEng-0 crashed, job Id: 67
Our investigations and findings…
1.     We disabled the entry Tk2Motif*fontMapCs: iso8859-1=UTF8 in Tk2Motif.rgb then started the server. We found that no error is thrown in the rwEng trace file and we are able to print the report also in PDF format… (Please see the attached japarial.pdf for your verification) but we are able to see only junk characters. We verified the document settings in the PDF file for ensuring the font sub set. We are able to see the font sub setting is used.
2.     If we enable the above entry then the rwEng trace throwing the above error (oracle toolkit error) and reports engine is crashed.
It will be a great help from you if you can assist us to resolve this issue…

}this does the same as your program: the for loop is the best for this, but i agree with the others read some tutorials on loops in java. As posted before java has no concept of the GoTo syntax, loops or recursion are your only options

Help required in compiling Java Code.

I have java1.6 installed on my PC but I want to compile my code in such a way that
it will run on PCs with lower versions of java installed.
I am not using any feature specific to java1.6 in my program.
I am using Netbeans IDE 6.1
Thanks in advance.

Im not 100% sure of this but I would of thought a program will compile on any version of java as long as you dont use classes that are exclusive to higher version of java
for example i would think if you comiled the helloworld tutorial on v.1.6 it will run on computers with lower versions.
However a program which uses the scanner class (i think exclusive to 1.6 or 1.5 not sure though) will not run on say 1.2
CalypsoIve tested to run an complied class(version 1.6) on an computer with jre 1.5 installed(before), and it doesnt work. Dont remember precisly the error but it didnt run atleast.

Executing tiny programming language compiled byte code with the JVM

Hello,
For a project, I am developing a simple programming language, with a syntax not unlike Pascal, which compiles to Java Byte Code. Currently I execute the compiled byte code using my own interpreter. This works OK, but what I'd like to do now is to execute the compiled byte code using the actual existing JVM. The compiled byte code resides in a text file upon compilation of a sample program written in my tiny programming language. Does anyone know how I may start to go about this? Thanks in advance.

The only way of getting a standard Java virtual machine to execute your java byte code, is to wrap it up into a completely valid java class file.
Any constants you use, must be put into the classes constant pool.
Any local variables will have to go into the local variable table of the method which uses them... etc, etc.
Something like ASM, would let you dynamically create a Java class file.

Compiling java code from a running java application

How does compiling of java code from a running java application work?
I found a class: com.sun.tools.apt.main.JavaCompiler
but cannot find any documentation of how this class works.

How does compiling of java code from a running java
application work?Probably most reliably using Runtime.exec().
I found a class:
com.sun.tools.apt.main.JavaCompiler
but cannot find any documentation of how this class
works.For a purpose. You are not supposed to use this class. With the next JRE release or implementation, it might not exist anymore - it's not part of the standard API.

Compile c code with makefile

i have the source code for a program on my mac and i dont really know how to compile it.
it has a makefile and all of the sources but i dont really know how to compile it
the source code is at this website
http://bcrypt.sourceforge.net/
how do i compile the code on os x
?

Hi--
First off, you have to have the developer tools installed. You can download the latest version at Apple's Developer web site:
http://developer.apple.com/products/online.html
Or, there will be an appropriate version for your OS located on the DVD or CD that contains your OS installation.
Since your code has a makefile, you simply need to open the Terminal application and change into the directory with your source code, and type make at the prompt. If you're not familiar with the Unix command line, I'd suggest any one of dozens of tutorials on how to maneuver around your computer in the Terminal. This is only one example:
