java.lang.UnsatisfiedLinkError: ars3wapi32 still after updating path variable

I am trying to set up On Demand Server in my local machine and when ever I am deploying the application on tomcat server I am getting below error message on browser. I have updated the PATH variable also.

Here is a guide the solution (for Windows and OnDemand V9.5).
First of all, you need to install ODWEK on the machine where you want to run your java app. Please install in the default folder, this whole thing is tricky enough as it is...
Set the environment variable "PATH" in Windows, add "C:\Program Files\IBM\OnDemand\V9.5\bin"
Set CLASSPATH in your development environment - point out the ODApi.jar file and ALSO point "Native library..." to the \bin folder above. (You can also call the program and setting the CLASSPATH in the call as a parameter: -Djava.library.path="C:\Program Files\IBM\OnDemand\V9.5\www\api\ODapi.jar"
Copy the file ars3wapi64.dll from C:\Program Files\IBM\V9.5\www to C:\Program Files\IBM\OnDemand\V9.5\bin
Ensure that all of these files are in the bin-catalog above:
**ars3wapi64.dll**
icudt53.dll
icuin53.dll
icuio53.dll
icule53.dll
iculx53.dll
icuuc53.dll
arsgsk64.dll
If you are getting the error "java.lang.UnsatisfiedLinkError: ars3wapi32 (Not found in java.library.path)" one of the above is most likely incorrect.
OR you could be using different versions of ODWEK and OnDemand.

Accessing HDFS on Cloudera with Java and Kerberos Keytab from Windows

I'm trying to connect to my HDFS instance running on Cloudera. My first step was enabling Kerberos and creating Keytabs (as shown here).
In the next step i would like to authenticate with a keytab.
Configuration conf = new Configuration();
conf.set("fs.defaultFS", "hdfs://cloudera:8020");
conf.set("hadoop.security.authentication", "kerberos");
UserGroupInformation.setConfiguration(conf);
UserGroupInformation.loginUserFromKeytab("hdfs#CLOUDERA", "/etc/hadoop/conf/hdfs.keytab");
FileSystem fs = FileSystem.get(conf);
FileStatus[] fsStatus = fs.listStatus(new Path("/"));
for (int i = 0; i < fsStatus.length; i++) {
System.out.println(fsStatus[i].getPath().toString());
}
It fails with the following error
java.io.IOException: Login failure for hdfs#CLOUDERA from keytab
/etc/hadoop/conf/hdfs.keytab:
javax.security.auth.login.LoginException: Unable to obtain password
from user
The question is: how do I correctly handle the keytab? Do i have to copy it to my local machine?

When running a Hadoop client on Windows to reach a kerberized cluster, you need a specific "native library" (i.e. DLL).
As far as I can tell there is no good reason for that, because that lib is not actually used outside of some automated regression tests (!?!) so it's a pain inflicted to Hadoop users by Hadoop committers.
To add extra pain, there is no official build of that DLL (and of the Windows "stub" that enable its use from Java). You must either (a) build it yourself from source code -- good luck -- or (b) search the internet for a downloadable Hadoop-for-Windows runtime, and pray that is does not contain any malware.
The best option (for 64-bit Windows) is here: https://github.com/steveloughran/winutils
...and the ReadMe explains why you can reasonably trust that run-time. But if you are stuck with an older 32-bit Windows, then you are on your own.
Now let's assume you deployed that run-time on your Windows box under
C:\Some Dir\hadoop\bin\(the final bin is required; the embedded space is just extra fun)
You must point the Hadoop client to that run-time with a couple of Java properties:
"-Dhadoop.home.dir=C:/Some Dir/hadoop" "-Djava.library.path=C:/Some Dir/hadoop/bin"
(note the double quotes around Windows args as a whole, to protect embedded spaces in the paths, which have been translated to Java style for extra fun)(in Eclipse, just stuff these props under "VM Arguments", quotes included)
Now, there's the Kerberos config. If your KDC is your corporate Active Directory server, then Java should find the config parameters automatically. But if your KDC is a standalone "MIT Kerberos" install on Linux, then you have to find a valid /etc/krb5.conf file on the cluster, copy it on your Windows box, and have Java use it with an additional property...
"-Djava.security.krb5.conf=C:/Some Other Dir/krb5.conf"
Then let's assume you have created your keytab file on a Linux box, using ktutil (or an Active Directory admin created it for you with some AD command) and you dropped the file under C:\Some Other Dir\foo.keytab
Before anything else, if the keytab is for a real Windows account -- i.e. your own account -- or a Prod service account, then make sure that keytab is secure!! Use the Windows Security dialog box to restrict access to your account only (and maybe System, for backups). Because that file could enable anyone, on any machine, to authenticate on the cluster (and any Kerberos-enabled system, including Windows).
Now you can try to authenticate using
UserGroupInformation.loginUserFromKeytab("foo#BAR.ORG", "C:/Some Other Dir/foo.keytab");
If it does not work, enable the Kerberos debug traces with both an environment variable
set HADOOP_JAAS_DEBUG=true
...and a Java property
-Dsun.security.krb5.debug=true
(in Eclipse, set these in "Environment" and "VM Arguments" respectively)

Do you have set proper permissions?
chown hdfs:hadoop /etc/hadoop/conf/hdfs.keytab
chmod 440 /etc/hadoop/conf/hdfs.keytab

Eclipse Warning When I try to run a GAE project

Am using this link as a reference so that I can be able run a GAE project locally. Am using the Google Plugin for eclipse.
When I click the button Run, i get WARNINGS in the console.

Without much clarity from you about your set up I can see that you need to clean up your Java installation.
It is complaining about finding a choice between two possibly different, but probably identical, classes called "JavaLaunchHelper".
You have one here :
{JAVAHOME}/Contents/Home/bin/java
You have another one here :
{JAVAHOME}/Contents/Home/jre/lib/libinstrument.dylib.
I believe it is also hinting that you fix it in the command line you use to launch Eclipse.
-server must be followed by an argument for servletContainerLauncher[:args]
If I were you I would try renaming the first of the two options temporarily, from ...
{JAVAHOME}/Contents/Home/bin/java
... TO ...
{JAVAHOME}/Contents/Home/binTEMP/java
Suck it and see, as they say in England. That might get you going, while borking up a whole bunch of other things.
Really, you need to read up on JAVA_HOME, JAVA_PATH and JavaLaunchHelper and how they must be prepared for your operating system. Having JRE and JDK both in your path can lead to all kinds of confusing behaviour.

Error in starting java application as windows services

I have downloaded commom-daemon tool and used with a java application. I have created a bat file as shown below

error code 1
UPDATED
When I run
prunsrv.exe //ES//sample
it shows
The data area passed to a system call is too small.
Failed to start service
Can any one help me in this?

I had the same problem. In my case (not yours exactly), the problem was the jvm.dll path, because the variable %JAVA_HOME% has spaces. So to solve this, I modify the assignment
set CG_PATH_TO_JVM=%JAVA_HOME%\jre\bin\server\jvm.dll
to
set CG_PATH_TO_JVM="%JAVA_HOME%\jre\bin\server\jvm.dll"
and that's all.
Also, you could check the variables assignment with this command:
prunmgr//ES//yourservicename_as_in_windows

To help others troubleshooting.
If you look at:
https://commons.apache.org/proper/commons-daemon/procrun.html
There is a parameter:
--LogPath
which defaults to:
%SystemRoot%\System32\LogFiles\Apache
A log file is generated there which contains some additional error messages and possibly useful information.
The original questioner changed the log path to:
set PR_LOGPATH=D:\logs
So looking there would be the appropriate thing to do in their case.

I also had this cryptic error message 'The data area passed to a system call is too small.' with no further information in either the startup log or the Windows/System32/LogFiles/Apache/ logs on Win 8/Server 2008.
I had renamed my packages and the --StartClass and --StopClass parameters were wrong.

I agreed with OscarSan that a space in %JAVA_HOME% could cause the "error code 1" problem. I solve this problem by re-installing JDK 1.8 to change the installation path from C:\Program Files Java\jdk1.8.0_144 to C:\Java\jdk1.8.0_144. Problem solved.

Java Stored Procedure using MQ

I need to create a Java stored procedure in Oracle. I have used IBM's sample class for creating an MQ message from a simple class outside of Java EE environment. I have tested the class by itself and it is working.
My Oracle vesrion is 11i.
When I am trying to add the jars used in the simple application to load to Oralce along with my simple class, I am getting errors about class not found, even if same jars work with the test case. I am stuck with this for over a week and am desperately hoping that someone would be able to help me with it.
Kinds of errors I am getting are like this from -v flag with loadjava utility on the client
on line 326 / 327, you see this:
creating : class com/ibm/mq/jms/admin/AP loading : class
com/ibm/mq/jms/admin/AP
and then at the end starting from line 6224 to end, it indicates that the above class can’t be resolved:
com/ibm/mq/jms/admin/APRCXI: ORA-29534: referenced object
xxxx.com/ibm/mq/jms/admin/AP could not be resolved
com/ibm/mq/jms/admin/APSDX: ORA-29534: referenced object xxxx.com/ibm/mq/jms/admin/AP could not be resolved exiting : errors
resolving class com/ibm/mq/jms/admin/AP
the command I used is:
c:\Oracle\product\11.2.0\client_1\bin\loadjava.bat -f -jarsasdbobjects
-prependjarnames -stoponerror -u xxxx/yyyy#SID -v -resolve lib\jms.jar lib\com.ibm.mqjms.jar lib\com.ibm.mq.jmqi.jar lib\dhbcore.jar
lib\fscontext.jar src\com\test\javasp\mq\JmsProducer.java
I also tried with -genmissing option with some additional jars ( list I found here ), but still get similar error for a different class.
Other issue with this that I am facing is that if I get an error and try to use the dropjava command from Oracle, it doesn't work either.
I also saw from this link, that this person was successful, but unfortunately, he/she didn't indicate how they used loadjava to load the jars.
If i can provide any other information, please let me know.
If anyoneone has any idea on how to get the Java Stored Procedure to use IBM MQ working with Oracle 11i, I would really appreciate the help.

Found a detailed answer in this blog entry. I tried it and it worked for me.

In Oracle there is no concept of CLASSPATH, so the standard MQ Client install is useless. You can only load the jars reference by your app within the database schema. Classes are resolved when loaded with the -r option. You can further on specify your own resolved using -r -Resolver (schemas). (check Oracle docs for exact format). So in effect the database schemas becomes the classpath.
Using Websphere MQ classes for Java poses a number of problems, you have to ensure that the Oracle JDK version is at an appropriate support level to connect to the chosen MQ server version. Check the system requirements for websphere MQ Vx.x. You should find IBM's web references. check the support for MQ classed for java.
I have such an issue at the moment trying to connect to Mq using Oracle 10 and JDK 1.4.2. I had to recompile my Java code using JDK 1.4.x. This does not work and I assume it is because I connect to MQ 7.0.1.7 which requires JRE 1.7 as minimum.
