AW: "Fatal Error: Unable to locate package java.lang in classpath or bootclasspath" when upgrading to Tomcat9

I think I remember this being an issue with XSP … it required an SDK and not just a Java Runtime as it needs to compile stuff at runtime.

Betreff: "Fatal Error: Unable to locate package java.lang in classpath or bootclasspath" when upgrading to Tomcat9
Hello Cocoon community,

I am encountering an issue while migrating from Tomcat7 to Tomcat9. I am working with Cocoon 2.1.13 and Java11.

During the deployment process I don't have any problems. However when I try to access the application, I got a white page  and this StackTrace is generated

org.apache.cocoon.components.language.LanguageException: Error compiling userinfos_xsp:
Line 0, column 0:

In the class org.apache.cocoon.components.language.programming.java.JavaLangugae I have checked the method compile and this error suggests a problem with the classpath or bootclasspath configuration. I have tried the following steps to address the issue without success:

- Checked and verified the Java installation and the "JAVA_HOME" environment variable. It is important to note that the installation works well with Tomcat7 and Java11
- Examined and updated the Cocoon configuration files, such as "cocoon.xconf," to ensure proper classpath settings. The parameter compiler is configured to work with org.apache.cocoon.components.language.programming.java.Javac

Despite these efforts, the issue persists. I suspect there might be an underlying compatibility issue or misconfiguration that I am overlooking.

If anyone has encountered a similar issue or has insights into resolving this problem, I would greatly appreciate your guidance and suggestions. Additionally, any general tips for configuring Cocoon with Apache Tomcat 9 would be highly appreciated.

Thank you in advance for your support and assistance.

Best regards,
