[jira] [Updated] (DBCP-544) Custom Shared ClassLoader not working
after migrated from Tomcat 7 to Tomcat 9.0.17
[ https://issues.apache.org/jira/browse/DBCP-544?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Akram updated DBCP-544:
-----------------------
Description:
Hi,
I have Custom SharedClassLoader in Tomcat 7 to load shared library jars,
which is used by different applications in that tomcat. We migrated to
Tomcat 9, now it is not working. How to achieve the same functionality in
tomcat 9.
In Tomcat 9 it expects resources to be passed. I don't find any sample Code
on how to populate resources.
I tried like below
public CustomSharedClassLoader(ClassLoader parent) throws Exception {
super(parent);
//The below three lines are added by me to work for Tomcat 9.
StandardRoot standardRoot = new StandardRoot();
standardRoot.addPreResources(new DirResourceSet());
setResources(standardRoot);// End for tomcat 9 changes.
for (URL urlForJars : getClassPath(SHARED_LIB))
{ addURL(urlForJars); }
start();
}
It didn't work.
public class CustomSharedClassLoader extends WebappClassLoader
{//Which takes shared folder libarary, it returns those classes.}
