Cause of 'tmpFile.renameTo(classFile)' during JSP compilation

问题

I'm using Jetty 6 server and sometimes this exception shows up:

java.io.IOException: tmpFile.renameTo(classFile) failed
    at org.apache.jasper.compiler.SmapUtil$SDEInstaller.install(SmapUtil.java:235)
    at org.apache.jasper.compiler.SmapUtil.installSmap(SmapUtil.java:158)
    at org.apache.jasper.compiler.Compiler.generateClass(Compiler.java:390)
    at org.apache.jasper.compiler.Compiler.__compile(Compiler.java:437)
    at org.apache.jasper.compiler.Compiler.compile(Compiler.java)
    at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:608)

Can this be solved by updating Jetty, or does exist any other way?

回答1:

I was using eclipse and in my case the issue was resolved by just reloading the page once again. The issue occurs first time, but on reloading the page once again I do not see the error.

Try to disable indexing tools, virus scanners and so on for .jsp files.

This issue can be resolved by just deleting the temp and deployment folders once. Do a fresh deployment and this will work.
