I have a Java application installed on a USB which the user should be able to run from any OS.
For this,
I'm packaging a JRE instance on the USB along with my application.
I'm having a FAT32 file-system on the USB.
However, the problem is, FAT32 has no concept of execute ("+x") permissions. While I can launch a shell script, like so:
$ sh /path/to/fat32-usb/helloWorld.sh
, and while I can launch a simple ELF binary, like so:
$ /lib64/ld-linux-x86-64.so.2 /path/to/fat32-usb/helloWorld
, I can't seem to be able to launch the Java ELF program. I get these errors:
Error: could not find libjava.so
Error: Could not find Java SE Runtime Environment.
Before launching java, I've tried setting these environment variables as follows:
export JAVA_HOME=/path/to/fat32-usb/jre
export LD_LIBRARY_PATH="$JAVA_HOME/lib/amd64:.:$LD_LIBRARY_PATH"
export PATH="$JAVA_HOME/bin:.:$PATH"
I have also tried launching java from inside the $JAVA_HOME/bin directory. Finally, I've also tried copying all the libXXX.so's from $JAVA_HOME/lib/amd64/ to $JAVA_HOME/bin, hoping that they would get picked up from the current directory, ., somehow.
But nothing has worked.
EDIT
Here are the last few lines of strace output:
$ strace -vfo /tmp/java.strace /lib64/ld-linux-x86-64.so.2 /path/to/fat32-usb/jre ...
...

write(2, "Error: Could not find Java SE Ru"..., 50) = 50
write(2, "\n", 1) = 1

EDIT2
And here is the output of ltrace (just a single line!):

This is ltrace excerpt around loading of libjava.so by a Java on an ext4 partition (and not the problem FAT32 partition), which I can load fine:

everyone, I am using tabula-py in python to extract table from pdfs. I used following codes.
import tabula
table_temp = tabula.read_pdf('./example_pdf/sample1.pdf',pages=11)
However, I got the error message as pasted below, in which I was told "no such file or directory: 'java'". I have installed Java in the following folder
"/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home".
Could anyone help me on solving the problem?
Thanks.

I had run into the same error. The line actually causing the error for me was subprocess.call('java').
Installing Java on my machine fixed the error for me.
If installing Java still doesn't solve the problem for you, try running which java, and add the output directory to your PATH environment variable.
I am trying to execute a perl script via a cron job that uses the system command to execute a java wrapper for boilerpipe. It fails when executed via cron. The script (simplified) is
my $link = "http://foo.bar"; # with a real link
my $cmdstring = 'java -jar boilerpipe-wrapper.jar url '.$link.' out.txt';
my $result = system($cmdstring);
if ($? == -1) {
print LOG "failed to execute system command: $!\n";
die;
}
elsif ($? & 127) {
printf LOG "child died with signal %d, %s coredump\n",
($? & 127), ($? & 128) ? 'with' : 'without';
die;
}
else {
printf LOG "child exited with value %d\n", $? >> 8;
die;
}
The die commands are in there for debugging purposes. What appears in LOG is
child exited with value 1
The crontab line is
24 7 * * * perl /home/retrievetext.pl >> /home/cron-msgs 2>&1
What appears in cron-msgs is
Error: unable to access jarfile boilerpipe-wrapper.jar
Died at /home/retrievetext.pl line 15
The ls -la for boilerpipe-wrapper.jar is
-rwxr-xr-x 1 steve sudo 1945275 Apr 29 03:53 boilerpipe-wrapper.jar
The Perl script and the system call work as expected when executed from the terminal. Anyone know what the problem is?

I manually patched the files generating those error and builded the image. It gave a new error but successfully wrote the image. Java in installed:
root#intel-corei7-64:~# java -version
java version "1.7.0_99"
OpenJDK Runtime Environment (IcedTea 2.6.5) (99b00-2.6.5)
OpenJDK 64-Bit Zero VM (build 24.95-b01, interpreted mode)
The solution is either:
Manually patch openjdk following
this
Use a newer version of openjdk. This can be achived using a more
recent commit for the meta-java repository or setting a newer
preferred version in the local.conf.
EDIT: Added guide link.
Guide
Since I'm using this image in an OpenSource project I made a little guide on how to overcome the problems I had during the building process.
The guide can be found here.
UPDATE: I upgraded the JRE and JDK version. The new guide can be found here. For the bravest among you there's also an installer script.
I've seen some links for counting the methods on Linux and MacOS, but I haven't seen anything for Windows. How do you count a number of methods in a .dex or .jar file?
After unsuccessful search for a solution, I wrote two simple batch/shell scripts that do that.
The first one, methodcount.bat, checks if the file is .dex or .jar, and if it's a .jar file, it processes it with dx into dex file and then calls the second one, printhex.ps1, that actually checks the number of methods in the dex file - it reads 2 bytes beginning at 88 (little endian) and converts them into a decimal number.
To use this you to have dx somewhere in your path (it's in the android SDK build-tools/xx.x.x folder) and have PowerShell installed (it should already be installed on Windows 7/8).
Usage is very simple: methodcount.bat filename.dex|filename.jar.
Here are the scripts, but you can also find them on gist: https://gist.github.com/mrsasha/9f24e129ced1b1db791b.

I see this question is old, but there's a Gradle plugin that will work on Windows which will report the method-reference count in an APK on each build: https://github.com/KeepSafe/dexcount-gradle-plugin.
I'm trying to install WWW::HTMLUnit on Windows 7. There're step that I run through:
Install Inline::Java 0.53
Install WWW::HTMLUnit 0.15
At step 2, after nmake, I type nmake test to test module but it failed. Here's output:

Stop.
From above log, I could see that:
class Error: com.gargoylesoftware.htmlunit.WebClient could not be found.
I have no idea that I missed anything.
Any help would be appreciated.
Thanks.

I found it.
There's different between path in Unix and Windows system. Unix uses ':' for a delimiter but Windows uses ';'. So what I've done is that open HTMLUnit.pm and change all of ':' to ';'.
With HTMLUnit version 0.15 I made changes at these lines below:
Line 78:
return join ';', map { "$jar_path/$_" } qw( # return join ':', map { "$jar_path/$_" } qw(
Line 127:
$custom_jars = join(';', #{$parameters{'jars'}}); # $custom_jars = join(':', #{$parameters{'jars'}});
Line 148:
CLASSPATH => collect_default_jars() . ";" . $custom_jars, # CLASSPATH => collect_default_jars() . ":" . $custom_jars,
And it works like a magic.
(it wouldn't let me comment on an existing answer)
I see your answer about ':' vs ';'. I'll try to include a fix in the next WWW::HtmlUnit release (I am the author of the perl bindings).
