PRWEB startup failure – PRMiniLoader cannot find prbootstrap JAR (Pega 8.23 on Tomcat 9)
Hello,
I am facing an issue starting the PRWEB application during a base Pega 8.23 setup on Apache Tomcat when I install Pega Infinity 23 .1.0 with multitenancy for PDC setup.
Environment
-
Pega version: Pega 8.23.0
-
Installer package: Pega8.23.0.zip
-
Application server: Apache Tomcat 9.0.115
-
Java: OpenJDK 17
-
OS: RHEL 9 EC2 AWS
When I followed the steps to install.sh and saw Build succeeded, I noticed the prweb.war is not found under webapps. So i manually copied from archives folder.
Issue Observed
During startup, PRWEB fails to initialize and the context does not start successfully.
From catalina.out, I consistently see the following error:
WARNING com.pega.pegarules.internal.bootstrap.PRMiniLoader.
Could not find file:
/opt/apache-tomcat-9.0.115/webapps/prweb/WEB-INF/lib/prbootstrap-8.23.0-110.jar
SEVERE org.apache.catalina.core.StandardContext.startInternal
Context [/prweb] startup failed due to previous errors
I troubleshoot and found the file at /opt/apache-tomcat-9.0.115/webapps/prweb/WEB-INF/lib/prbootstrap-8.23.0-110.jar and chmod 755 already. Not sure why Tomcat startup script ignore this.
