Additional Steps for Using the IBM JDK

If you are using the IBM JDK, you need to set OWASP to use the correct Pseudo-random Number Generator (PRNG). To do this before installation, you can modify the WAR file as follows:

1. The WAR file is an archive format in a single file.
a. Extract the Websphere.jrs.csrfguard.properties file using the following command: 
cd <js-install>
"%JAVA_HOME%/bin/jar" xf jasperserver-pro.war WEB-INF/csrf/Websphere.jrs.csrfguard.properties

This creates the WEB-INF/csrf folder in the current location and places the extracted file there.

b. Rename the file from Websphere.jrs.csrfguard.properties to jrs.csrfguard.properties using the following command: 
mv ./WEB-INF/csrf/Websphere.jrs.csrfguard.properties ./WEB-INF/csrf/jrs.csrfguard.properties
2. After you have modified the file, replace it in the WAR file archive using the following commands. 
cd <js-install>
"%JAVA_HOME%\bin\jar" uf jasperserver-pro.war WEB-INF/csrf/jrs.csrfguard.properties
