java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader

[Nick Sher]

Hello,

I am not sure what is going on here. It runs fine on one machine but not the other. Here is the stracktrace:

Caused by: java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstr
ap classloader, but this RI (from jar:file:/I:/.../WEB-INF/lib/
jaxb-impl.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API.
 Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap cla
ssloader. (See http://java.sun.com/j2se/1.5.0/docs/guide/standards/)

I have JDK 6 on both machines and tomcat 6.

I googled a bit about this issue but no help. The online help talked about copying few jars to endorsed directory. But I don't have any endorsed directory in JDK, JRE or Tomcat.

Please help.

You don't have an endorsed standards directory? Then make one. Unfortunately the link mentioned in the stack trace seems to be broken at the moment, while Oracle moves all the Java pages from sun.com to oracle.com. (but you did try to follow it, didn't you?) So here's a link to someone else who explains it for you, which I found after a couple of minutes googling: http://futuretask.blogspot.com/2005/01/java-tip-4-endorsed-standards-override.html.
