<DIV><FONT size=2>I was having trouble with <FONT size=2>version 4.3.17 and
a ClassCastException when the opencms servlet initializes and tries to cast the
Sun Class Loader to a CmsClassLoader on Tomcat 3.2.1</FONT></FONT></DIV>
<DIV><FONT size=2><FONT size=2> </DIV>
<DIV><FONT size=2>If I run the opencmsboot stuff it's fine so I looked at the
com.opencms.boot.OpenCmsHttpServlet source and find in line 80 that it
instatiates a brand new CmsClassLoader and uses that with no problem. However
the com.opencms.core.OpenCmsHttpServlet does the following in line 701
:-</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>CmsClassLoader loader = (CmsClassLoader)
(getClass().getClassLoader());</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>This throws the exception </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV>java.lang.ClassCastException: sun.misc.Launcher$AppClassLoader<BR>at
com.opencms.core.OpenCmsHttpServlet.init(OpenCmsHttpServlet.java:701)<BR>at
com.opencms.boot.OpenCmsServlet.init(OpenCmsServlet.java:89)<BR>at
org.apache.tomcat.core.ServletWrapper.doInit(ServletWrapper.java:317)</DIV>
<DIV> </DIV>
<DIV><FONT size=2>I can't see a valid reason why it should prefer to
cast the existing loader rather than instantiate a new CmsClassLoader. So I
changed the offending line to :-</FONT></DIV>
<DIV> </DIV>
<DIV>CmsClassLoader loader = new CmsClassLoader() ;</DIV>
<DIV> </DIV>
<DIV>I hope this finds it's way into the release source.</DIV>
<DIV> </DIV>
<DIV>I am also having trouble publishing due to the session problem e.g.</DIV>
<DIV> </DIV>
<DIV>java.lang.NullPointerException<BR> at
org.apache.tomcat.core.RequestImpl.getSession(RequestImpl.java:480)<BR> at
org.apache.tomcat.facade.HttpServletRequestFacade.getSession(HttpServletRequestFacade.java:387)<BR> at
com.opencms.file.CmsRequestContext.getSession(CmsRequestContext.java:173)<BR> at
com.opencms.workplace.CmsAdminPublishProjectThread.run(CmsAdminPublishProjectThread.java:62)</DIV>
<DIV> </DIV>
<DIV>appears in my stderr</DIV>
<DIV> </DIV>
<DIV>I have seen discussion about this in the mail archive but no soluion.
Please help me someone.</DIV>
