Latest JAVA ISSUES

We have suggested using Oracle (previously Sun Microsystems) JAVA for many years, but recent events has changed our thinking.

Oracle will no longer provide free continuing support (updates) for OpenJDK LTS versions at https://jdk.java.net

AdoptOpenJDK does provide support at https://adoptopenjdk.net/ .

AdoptOpenJDK is now distributing OpenJDK msi installers. The installers will optionally updated the PATH and JAVA_HOME. We recommend removing Oralcle JAVA with the operating system supported method and installing OpenJDK 11 LTS. Version 7.0.2 of the ResCarta Toolkit supports OpenJDK 11.

AdoptOpenJDK is also providing updates to OpenJDK 8.

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.

http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

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

For those running "ix" operating systems ...

$ sudo apt-get install openjdk-11-jdk

$ 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 experiencing some malfunction. We advise updating JAVA only if you need to do so for some known reason.

Disable the Print Function in ResCarta-Web

How can i completely disable the print function in ResCarta-Web?

The jsp file that contains the print function button is called RcWebImageViewerToolbar.jsp

The line of jsp code that controls the sort is listed below.

<td>

</td>

You can simply rem out the lines by cutting the --> from the print line and replacing it below the three lines of code like...

Save the edited file and restart your ResCarta-Web. You may want to clear your tomcat work directory prior to restarting do insure your changes are recompiled. ( N.B. The Tomcat Server work directory NOT the ResCarta-Web/work directory)

No Subjects in my OAI xml files

I used the OAI perl script and the resulting xml files do not contain subject information. I know the data is in my collection mangager view. What's up with that?

There is a known bug in version 2.0 of the RcOai.zip

If you use lower case text for the authority, subjects will not be extracted properly. Please download the

2.2 version of the ResCarta OAI kit and replace only your makeOAI.pl file. It is case independent now.

Windows Installer EXE fails (2009-09)

When I attempt to install the ResCarta Toolkit from the Windows .EXE file, I get a BOING!# sound and then nothing?

We have had this reported on certain newer Windows XP systems with more than 2 gigabytes of ram. The work around is to install from the .JAR file. Just download the ResCarta toolkit jar installer and double click like you would the exe file.

We have yet to determine the culprit. We can have the same version, service pack, and updates on two similar but not exact hardware systems and see the BOING!# on one and not the other. Hopefully we can resolve this shortly.

NOTE: It has been determined that the Java virtual machine is taking more memory that it can use. Machines with 2 gigabytes of ram on Windows XP will take 1638 megabytes of ram for the JVM. Any machine running Windows XP with more than 2 gigabytes of ram will exceed the XP JVM limit of 1650 megabytes. We have corrected this problem in version 2.2.1.

More memory needed

How do I work on larger collections without running our of memory ?

The start batch files and sh files for RcTools have a setting for your Java maximum memory. You can make this larger for your collections by adjusting the -Xmx setting. The default is -Xmx512m for 512 megabytes of memory. If your tool reports an out of memory error you can increase this setting to available memory in the machine less start up. So a machine with 2 gigabytes of ram could easily be set to -Xmx1024m for this setting.

You can find the batch files under your installation directory. For Windows the default location is C:\Program Files\RcTools\bin\ and on Mac OSx installs the default is the /Applications/RcTools/bin directory.
