Frequently Asked Questions Frequenty Asked Questions


Here you will find commonly asked questions of the ResCarta support team...

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


$ 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.




Tomcat Default Port

I can't see my ResCarta-Web site from outside my institution?


The default port for the Apache Tomcat service is 8080.  This port is defined for HTML traffic along with the more often used port 80.  On many campus networks all high ports are blocked.   This means the high HTML port of 8080 is also blocked.

If your server is not using port 80 for any other server (APACHE, IIS), you can change the default port of your Apache Tomcat server to port 80 by editing the  server.xml file located in the conf directory. Look for the connector which should be set to 8080. It should be like the following...

<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000" redirectPort=

"8443" />

Change the 8080 to 80 and restart your Tomcat service.

 <Connector port="80" protocol="HTTP/1.1"connectionTimeout="20000"

redirectPort="8443" />

 If your server is also running IIS and it is located on port 80,  your Tomcat service will not start.  To run both IIS and Tomcat and use a sinlgle port 80 will require a more extensive configuration of both IIS and tomcat.

Seeing Double

I know my data is good but when I copied it from my work area the collection manager does not recognize it as valid data. What could be wrong?

Sometimes while coping using a drag and drop method your mouse may have been a bit off the mark when you dropped your data.  Look for the occurance of another RCDATA01 directory under your top-level RCDATA01 directory.  It might look like  C:\mydata\RCDATA01\myinstid\RCDATA01\myinstid\myaggreg\00000516 

You might have just dropped the RCDATA01 into a lower directory. Since the collection manager looks up and down the tree for valid ResCarta data formats it can be confused by multiple top level names. 

IIS installation

Will ResCartaWeb interfere with my IIS installation?

 No, ResCartaWeb runs under the Apache Tomcat server, so there is required interaction with IIS.

 You can, however, use tomcat as a service which is called from IIS.  This will allow you to forgo the dreaded default 8080 address. Using IIS as a front end to your tomcat will also allow the use of WindowsR authentication if needed.
