Latest JAVA supported version is  1.8.0_181

 

The most asked question concerns the use of 32bit JAVA on a 64bit machine.  It you are using a 64bit operating system, download the 64bit JAVA from Oracle.  The current url for JAVA 8 from Oracle is.

Take care not to update to unsupported versions of 9, 10 or 11

For those running "ix" operating systems ...

$ sudo apt-get install openjdk-8-jre

or 

$ su -c "yum install java-1.8.0-openjdk"

 

During the installation of the ResCarta Toolkit you will see that the installer selects 32bit or 64bit options based on your installed JAVA. If you run 32bit JAVA on a 64bit machine you will get poor performance and have access to only one gigabyte of memory.

Most ResCarta problems over the years involve early untested releases of JAVA by Oracle. See the history of releases at wikipedia.  If you see a release date within a day or two of another release date, chances are you will be experiecing some malfunction.  We advise updating JAVA only if you need to do so for some known reason.

Root Identifiers

Should I pick my own root identifier or let the program create one?

The METADATA Creation tool will assign a sequential number as a root identifier by default. This is to assist you in creating unique root ids. If you want to tag your digital objects with your own UNIQUE eight character identifier you can just overwrite the number presented in the dialog box. Remember however that these ids must be kept unique.
