CDH4 Hadoop Ubuntu precise server

I got this error "JAVA_HOME "
When trying to install CDH4 of Cloudera Hadoop standalone version.
Although i did all the needed configuration + echo $JAVA_HOME is fine.
+ writing "java" works + writing "java -version" works ok .
Nothing really helped except
1. go to /etc/hadoop/conf
2. edit hadoop-env.sh
add export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_32
then try again, i was trying to format the namenode.

Hoped it helped.

Eclipse is running in a JRE, but a JDK is required

Hi,
1) Right click on windows eclipse shortcut.
2) add in the end of the Target "-vm pathtojdkliberary"
3) Ensure that the JRE library is setup correctly within eclipse->preferences->JRE
Solution refers both to MyEclipse (not matter if its the Blue version or the regular) and Eclipse.
That's it.

Spring LDAP dynamic connecting

Hi,
Lately i saw a question in one of spring ldap forums, were one of guys there asked this question:
How can i connect ldap without using spring xml (application context xml file).
My answer to him was that that i prefer and need in my project to use it dynamically intead of known configuration that can be configured in spring application context file (beans).
This was my solution for him:
LdapContextSource ldapContextSource = new LdapContextSource();
ldapContextSource.setUrl("ldap://localhost:portnumber");
ldapContextSource.setBase("ou=users, ou=system");//*
ldapContextSource.setUserDn("username to connect");
ldapContextSource.setPassword("password");
ldapContextSource.afterPropertiesSet();
//* the base is not necessary needed, it depends what do you need.
Bye,
Dor
