Hi,

I have to run some shell program provided by Paypal for encrypting their buttons.

In the build-app2.sh program they give:

#!/bin/bash

export CRYPTO_HOME="/x/home/dhan/java_client/crypto-124"

if [ ! -d ${CRYPTO_HOME} ]; then
	echo cannot find crypto distribution ...
	return 1;
fi

CLASSPATH="."
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bcprov-jdk14-124.jar"
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bcpg-jdk14-124.jar"
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bctest-jdk14-124.jar"
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bcmail-jdk14-124.jar"
export CLASSPATH

JAVA=/x/contrib/j2sdk1.4.0/bin/java
JAVAC=/x/contrib/j2sdk1.4.0/bin/javac
JAR=/x/contrib/j2sdk1.4.0/bin/jar

echo
echo "Be sure Java version is at least 1.4"
$JAVA -version
echo ; echo ; #sleep 3


echo "CLASSPATH="
echo $CLASSPATH
echo

echo compiling java files ...
$JAVAC -g -classpath "$CLASSPATH" 	                \
	ButtonEncryption.java	\
	com/paypal/crypto/sample/*.java

echo "Done!!!!!"

Open in new window


I have to change the paths.

I'm wondering about JAVA path section:

JAVA=/x/contrib/j2sdk1.4.0/bin/java
JAVAC=/x/contrib/j2sdk1.4.0/bin/javac
JAR=/x/contrib/j2sdk1.4.0/bin/jar

Open in new window


when I login as my user and su and type:
which java
/usr/bin/java

I get this output in the bin folder:
ls -al | grep 'java'
lrwxrwxrwx  1 root root          22 Jan 13 18:21 java -> /etc/alternatives/java*
lrwxrwxrwx  1 root root          23 Jan 13 18:22 javac -> /etc/alternatives/javac*
lrwxrwxrwx  1 root root          25 Jan 13 18:22 javadoc -> /etc/alternatives/javadoc*
lrwxrwxrwx  1 root root          23 Jan 13 18:22 javah -> /etc/alternatives/javah*
lrwxrwxrwx  1 root root          23 Jan 13 18:22 javap -> /etc/alternatives/javap*

So I have to change the JAVA paths to:
JAVA=/usr/bin/java
JAVAC=/usr/bin/javac
JAR=?

But where do I find the jar files for the java sdk? I'm not quite sure even I installed the java sdk though. Still new to Java.

I'm on a VPS on Godaddy using WHM/cPanel. It's Centos 5.9.

Thank you,
Victor

JAR is Java Archive tool which you will find inside your jdk folder.

Inside windows, it is located at
D:\Java\jdk1.7.0\bin\jar.exe

If you install JDK, then check out your directory,

/usr/lib/jvm/jre******/bin
/usr/lib/jvm/java-xxxxx/lib/tools.jar

Does it matter which one I use?

 [/usr/lib/jvm]# ls -al
total 36
drwxr-xr-x  3 root root  4096 Jan 13 18:22 ./
drwxr-xr-x 73 root root 28672 Jan 13 18:21 ../
lrwxrwxrwx  1 root root    26 Jan 13 18:22 java -> /etc/alternatives/java_sdk/
lrwxrwxrwx  1 root root    32 Jan 13 18:22 java-1.7.0 -> /etc/alternatives/java_sdk_1.7.0/
lrwxrwxrwx  1 root root    27 Jan 13 18:22 java-1.7.0-openjdk -> java-1.7.0-openjdk-1.7.0.25/
drwxr-xr-x  7 root root  4096 Jan 13 18:22 java-1.7.0-openjdk-1.7.0.25/
lrwxrwxrwx  1 root root    34 Jan 13 18:22 java-openjdk -> /etc/alternatives/java_sdk_openjdk/
lrwxrwxrwx  1 root root    21 Jan 13 18:21 jre -> /etc/alternatives/jre/
lrwxrwxrwx  1 root root    27 Jan 13 18:21 jre-1.7.0 -> /etc/alternatives/jre_1.7.0/
lrwxrwxrwx  1 root root    31 Jan 13 18:21 jre-1.7.0-openjdk -> java-1.7.0-openjdk-1.7.0.25/jre/
lrwxrwxrwx  1 root root    29 Jan 13 18:21 jre-openjdk -> /etc/alternatives/jre_openjdk/

There is a:
java_sdk or
 java_sdk_1.7.0 or
 java-1.7.0-openjdk-1.7.0.25

Java symlinks can be nightmarish. Since you seem to have java set up pretty well, try the following simplification

#!/bin/bash

export CRYPTO_HOME="/x/home/dhan/java_client/crypto-124"

if [ ! -d ${CRYPTO_HOME} ]; then
echo cannot find crypto distribution ...
return 1;
fi

CLASSPATH="."
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bcprov-jdk14-124.jar"
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bcpg-jdk14-124.jar"
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bctest-jdk14-124.jar"
CLASSPATH="$CLASSPATH:$CRYPTO_HOME/jars/bcmail-jdk14-124.jar"
export CLASSPATH

echo
echo "Be sure Java version is at least 1.4"
java -version
echo ; echo ; 


echo "CLASSPATH="
echo $CLASSPATH
echo

echo compiling java files ...
javac -g -classpath "$CLASSPATH" 	                \
ButtonEncryption.java	\
com/paypal/crypto/sample/*.java

echo "Done!!!!!"

Open in new window


Obviously the path given by $CRYPTO_HOME has to exist and all those crypto jars under it must be correct
