MATLAB: Am I unable to deploy the documentation example WebFigureQuickStart.war on Apache Tomcat 6.0 Web Server using MATLAB Builder JA 2.2.2 (R2011a) on 64-bit Linux

MATLAB Compiler SDK

When I try to deploy the example WAR I get the following error:

<SNIP>

Could not access the MCR component cache

<SNIP>

Best Answer

This is due to missing permissions on the directory to which the MCR Cache is written. Enable MCR_CACHE_VERBOSE as described in the below web page and check permissions on the MCR Cache path returned.

MATLAB: Am I getting a java error when trying to run the java class compiled by MATLAB Builder JA 2.2.3 (R2011b)

The MathWorks javabuilder.jar java library is missing. Make sure the javabuilder.jar file is added to the java class path when running your java class, as below:

java -classpath <mwroot>/toolbox/javabuilder/jar/javabuilder.jar:foo.jar foopackage.fooclass

where mwroot is either the MATLAB root directory (if running against MATLAB) or the MCR root directory (if running against the MCR).

If you have another java application that utilizes the compiled java class, make sure to also import it as below:

import com.mathworks.toolbox.javabuilder.*

MATLAB: Do I receive an error when I am attempting to use the WebFigures example using Builder JA 2.0.3 (R2009a)

A Tag Library Descriptor (TLD) file is required for using custom JSP tags. The 'webfigures.tld' file is included within 'javabuilder.jar'. If there are more than one "javabuilder.jar" files, possibly of different versions, on the web server, the intended 'webfigures.tld' file will not be resolved correctly and thus the above error message will be generated.

To resolve the issue, check that there is only one copy of "javabuilder.jar" in the web server's common library directory. If you are using an Apache Tomcat Web Server version 6.0, place the "javabuilder.jar" file in the "lib" folder in the Tomcat installation directory.

For example, if the home directory of Tomcat server is declared as CATALINA_HOME environment variable then the javabuilder.jar should be placed in CATALINA_HOME/common/lib directory."
