deploying java through Cygwin - java

My Java development done in a windows machine and i run my processes on a centos machine.
I have a bash script that build all my Jars and SCP them to my centos machine. i run this bash script in Cygwin (java -version is 1.5.0_12), but when i try to run the process in my centos machine, the jVM can't open the Jars. also, running jar -tf throws:
java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(ZipFile.java:114)
at java.util.zip.ZipFile.<init>(ZipFile.java:75)
at sun.tools.jar.Main.list(Main.java:979)
at sun.tools.jar.Main.run(Main.java:224)
at sun.tools.jar.Main.main(Main.java:1149)
so the only way i can deploy is running mvn commands in cmd.exe in order to build my jars and then copy everything using WinSCP (that way i have no problems in the jars).
is there any known problem running mvn in cygwin?
(running mvn -version returned
Apache Maven 2.2.1 (r801777; 2009-08-06 22:16:01+0300)
Java version: 1.6.0_26)
thank you

Solved it.
i found the solution in cygwin sets file permission to 000
Edit /etc/fstab and add this line at the end of the file:
none /cygdrive cygdrive binary,noacl,posix=0,user 0 0
Then close all Cygwin processes, open a new terminal and ls -l on your files again.

Maven being a Java application runs the same whether launched via Cygwin script or cmd.exe. The Java executable in this case is the same tool.
First, you might want to post the copy command you are using in the bash script. Secondly, have you checked the permissions on the jar files once they are pushed to the CentOS box? Are the files actually readable to the process owner when sent via your bash script and are the owners/permissions the same as when copied using WinSCP?

Will below command work as it as on jenkins for running my jar file with command line arguments?

I have built an executable jar file which is also a standalone SpringBoot Application. The requirement is that I have to run this jar file from command line which also provides command line arguments which are meant to override application.properties properties and will be used further.
I have tried and this works perfectly when ran from Windows Command Prompt.
Now I further want to deploy this on jenkins and run the same jar file usign jenkins using the command:Note that the command is important since it overrides application.properties.
Will it work in jenkins? Should i go with "Execute Shell" or "Execute Windows batch command" for it in jenkins? I would be trying it but need o know .
Command: java -jar myJArName.jar --server.port=10 --another.argument=1 --another.argument=2
Yes, you can use execute shell as you mentioned above if:
Java is installed on the host that Jenkins runs on
java is part of $PATH (you can check this by running which java on your jenkins host)
myJarName.jar is actually on the host jenkins runs on
Btw. I assume Jenkins runs on a Linux host. Otherwise you might have to use Execute Windows batch command which will work in a similar way to execute shell, but I never used it.

I am getting the following error when I run mvn on OS X Mavericks: Cannot run program "/bin/sh": error=2, No such file or directory

I am running OS X Mavericks on a MacBook Pro.
I have maven 3.0.5 installed.
When I run mvn, I am getting the following error message.
Error while executing process. Cannot run program "/bin/sh": error-2, No such file or directory
And before you ask:
PATH="/usr/local/apache-maven-3.0.5/bin:/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin:/usr/local/bin:/bin:/usr/bin"
M2_HOME="/usr/local/apache-maven-3.0.5"
M2="/usr/local/apache-maven-3.0.5/bin"
MAVEN_OPTS="-Xms256m -Xmx768m -XX:MaxPermSize=512m"
I am also seeing the following near the beginning of the mvn output:
[WARNING] Some problems were encountered while building the effective settings
[WARNING] Failed to use environment variables for interpolation: Cannot run program "env": error=0, spawn failed #
I had the same problem: exec() failed with ANY executable. Finally remembered that I was using a private jre. That jre was a copy of the original one, just with bin/java set as executable.
I made lib/jspawnhelper executable and it worked!
If you are using eclipse , this is due to the java version. point java to your OS java instead of eclipse java. this will be solved
It seems your system is missing the "sh" shell to start interpreting the script.
I just looked up installed shells on Mac OSX and got this result:
/bin/zsh
/bin/ksh
/bin/tcsh
/bin/bash
/bin/sh
So when "/bin/sh" is missing, try "/bin/bash" for example.
Better:
Check if "/bin/sh" exist
If exist check if the user which runs the command can execute the shell
Because it can be possible that the shell binary exist but isn't executable for you. Then you have to make it executable for the user trying mvn.
Hope that helps ;)

How to run ZooInspector from Windows

Here's what I did:
Downloaded Apache ZooKeeper 3.4.6 (.tar file), extracted to C:\cygwin\home\user\zookeeper-3.4.6\
Ran ant at the root of the ZooKeeper folder (C:\cygwin\home\user\zookeeper-3.4.6)
Navigated to C:\cygwin\home\user\zookeeper-3.4.6\contrib\ZooInspector\
Ran ant, and I get the following error:
Output:
Buildfile: C:\cygwin\home\Jean\zookeeper-3.4.6\contrib\ZooInspector\build.xml
BUILD FAILED
C:\cygwin\home\user\zookeeper-3.4.6\contrib\ZooInspector\build.xml:19: Cannot find C:\cygwin\home\user\zookeeper-3.4.6\contrib\build-contrib.xml imported from C:\cygwin\home\user\zookeeper-3.4.6\contrib\ZooInspector\build.xml
Total time: 0 seconds
This leaves me with no .cmd or .sh file to execute. How come the build-contrib.xml file isn't there?
Also, I noticed that there seems to be an already-compiled ZooInspector JAR file: zookeeper-3.4.6-ZooInspector.jar. However, attempting to run it with the following command yields failure too:
$ java -cp zookeeper-3.4.6-ZooInspector.jar:lib/* org.apache.zookeeper.inspector.ZooInspector
Error: Could not find or load main class org.apache.zookeeper.inspector.ZooInspector
This is a bit frustrating -- setting up the ZooKeeper server was straightforward but for some reason I just can't figure out how to run this standalone GUI. What am I missing?
For windows:
#echo off
set cp="./*;./lib/*;../../*;../../lib/*"
java -cp %cp% org.apache.zookeeper.inspector.ZooInspector
ZooInspector 3.4.6 (that's bundled with ZooKeeper 3.4.6) doesn't seem to be able to connect to a running ZooKeeper instance on Windows.
Better use zkui:
https://github.com/echoma/zkui/wiki/Download
zooInspector just need 3 libraries and 1 jar to load the main class.
the mainclass lives zookeeper-3.3.0-ZooInspector.jar and it needs jtoaster-1.0.4.jar, zookeeper-3.3.0.jar and finally log4j-1.2.15.jar
After download the tar.gz file from apache servers, you must untar and build with ant. finally copy the zookeeper-3.3.0.jar and log4j-1.2.15.jar to contrib/ZooInspector/lib/. Finally cd to contrib/ZooInspector and launch this command
java -jar zookeeper-3.3.0-ZooInspector.jar -cp lib/*
I met the same issue today, and created a pre-compiled version, which should work on Windows as well. You can find details here:

Error launching sqoop client on windows

Per the installation directions I run:
./bin/sqoop.sh client
and it returns error:
could not find or load main class org.apache.sqoop.shell.SqoopShell
I'm setting up Sqoop for the first time. I have the server up and running on Redhat Linux. Now I am stuck running the client on Windows Server 2012. I am running hadoop v2 and sqoop-1.99.3-bin-hadoop200. At the command line I verified java is installed by running "java -version" at the command line and seeing "1.8.0". Scoop is written in Java 1.6. Does that matter? I'm having difficulty locating an active download link to 1.6 for windows for troubleshooting.
I tried installing Cygwin and running the command. Same error.
Locate the directory traversal for the case of client in sqoop.sh
# Build class path with full path to each library
for f in $SQOOP_CLIENT_LIB/*.jar; do
CLASSPATH="${CLASSPATH}:$f"
done
Just add the following search and replace params (note changes of colon to semicolon in classpath)
# Build class path with full path to each library
PARAMSEARCH="/c/"
PARAMREPLACE="C:\\"
for f in $SQOOP_CLIENT_LIB/*.jar; do
f=${f/$PARAMSEARCH/$PARAMREPLACE}
CLASSPATH="${CLASSPATH};$f"
done
I had the same issue running on Windows 8.1. Turns out it's caused because sqoop.sh uses POSIX style directory paths. So / instead of . This results in the script being unable to set the correct CLASSPATH. This could have been remedied by using a cmd file for Windows. I don't know why they didn't do it. There are cmd files for catalina and such but not for launching sqoop!
Anyway I got around this issue by adding all the jar files in the shell\lib folder to CLASSPATH. You do have to add each & every jar file there and not just the folder path. A restart was required after this which was annoying. However the shell script will still not launch the client even after this change. The little trick I used is to just launch the client at the command prompt from the shell\lib folder with the following command
***java org.apache.sqoop.shell.SqoopShell***
Now I get the groovy prompt from where I can run all the commands provided here
I used the following steps to configure sqoop in a windows machine and now able to work with sqoop 1.99.3 successfully.
*Cygwin must be installed before continuing further steps. Also its just for using the native libraries, we can interact with sqoop directly from windows command prompt.
Save the sqoop package folder in “C:” drive name as sqoop
Copy the hadoop lib folder “hadoop” from C:\hadoop\share into C:\usr\lib\hadoop [If this directory doesn't exists, then create one]
Change the hadoop configuration properties in the file “sqoop.properties” from the location “C:\sqoop\server\conf” as below
at line:132
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=C:\hadoop\etc\hadoop
Copy the sqoop.properties and sqoop_bootstrap.properties from “C:\sqoop\server\conf” into “C:\sqoop\server\bin”.
Set the environment variables for sqoop home as well as path:
SQOOP_HOME = C:\sqoop
Starting the server:
Open Command prompt (run as Administrator) and enter into the $SQOOP_HOME location and type command as follows
C:\sqoop> cd server\bin
C:\sqoop\server\bin> catalina start
The catalina server will be start and check it in the below location
http://localhost:12000/sqoop
Client Shell Command
Open the command prompt and enter the following command
java -classpath C:\sqoop\shell\lib\sqoop-shell-2.0.0-SNAPSHOT.jar;C:\sqoop\shell\lib\sqoop-common-2.0.0-SNAPSHOT.jar;C:\sqoop\shell\lib\sqoop-client-2.0.0-SNAPSHOT.jar;C:\sqoop\shell\lib\log4j-1.2.16.jar;C:\sqoop\shell\lib\json-simple-1.1.jar;C:\sqoop\shell\lib\jline-0.9.94.jar;C:\sqoop\shell\lib\jersey-core-1.11.jar;C:\sqoop\shell\lib\jersey-client-1.11.jar;C:\sqoop\shell\lib\jansi-1.7.jar;C:\sqoop\shell\lib\hamcrest-core-1.3.jar;C:\sqoop\shell\lib\groovy-all-1.8.5.jar;C:\sqoop\shell\lib\commons-lang-2.6.jar;C:\sqoop\shell\lib\commons-cli-1.2.jar org.apache.sqoop.shell.SqoopShell
The client shell command will be displayed as :
Sqoop Shell: Type 'help' or '\h' for help.
sqoop:000>
Hope this helps
Thanks

Unable to run threaded java jar file on Mac OS X 10.6.8 with Java 1.7.0.45 using pacifist

I have installed Java 1.7.0_45 on Mac OS X 10.6.8 using Pacifist [http://www.charlessoft.com/] however I am unable to run a jar file which I have downloaded. The jar file is a threaded application.
The error message I am getting is:
java -jar context.jar
2013-10-31 14:14:41.898 java[330:a07] *** NSInvocation: warning: object 0x109356390 of class 'ThreadUtilities' does not implement methodSignatureForSelector: -- trouble ahead
2013-10-31 14:14:41.900 java[330:a07] *** NSInvocation: warning: object 0x109356390 of class 'ThreadUtilities' does not implement doesNotRecognizeSelector: -- abort
Trace/BPT trap
Is there anyway I can run the jar. I have set the JAVA_HOME path properly and java -version is showing 1.7.0_45 as the version.
The same application works properly on Windows Java 1.7.0_45 and also on Linux Java 1.7.
The web search for the solution and the given keywords return very few results and none of them have any specific solution in it. I am new to mac so I am not fully able to understand the issue.
Alternatively, is there anyway I can run Java from folder in Mac like I can do in windows and Linux by just extracting the Java contents and changing the JAVA_HOME. If that is possible then I should be able to run my JAR.
I had kind of same problem while installing an application through jar file, my Java was not detected by the jar application installer,
Over here I see that one of the method is not accessible, could be a same problem. But I am not very sure of it.
make sure you have rt.jar in your JAVA_HOME/jre/lib/ folder
In case you don't have then you are required to have it through the process of creation of symbolic link.
In the command below replace your_java_version with proper version matching your requirement.
sudo mkdir -p /System/Library/Frameworks/JavaVM.framework/Versions/<your_java_version>/Home/jre/lib
Go into the directory:
cd /System/Library/Frameworks/JavaVM.framework/Versions/<your_java_version>/Home/jre/lib/
Create symbolic link :
sudo ln -s ../../../Classes/classes.jar rt.jar
Hope this solves your problem.
I get the exact same problem with MacOS 10.6.8 and JDK 7. In order to run the jar I had to use the System JRE which is 1.6.x (In my case I wanted to install Squirrel
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -jar >squirrel-sql-3.6-MACOSX-install.jar
