Tomcat – java.lang.InternalError: name is too long to represent
I’ve got the aforementioned exception when I was trying to load a jsp page on Tomcat 6 running in a debug mode. Turns out the problem occurs when a jsp page grows big. It’s a known JVM issue described by bugs 39089 and 6294277. Here is how to solve it without touching the jsp.
Open conf/web.xml In your Tomcat install directory and add a supressSmap parameter to the jsp servlet:
<servlet> <servlet-name>jsp</servlet-name> <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class> .. <init-param> <param-name>suppressSmap</param-name> <param-value>true</param-value> </init-param> .. </servlet>
SMAP stands for a source map generator (see Javadoc – SmapGenerator). Suppressing it will prevent the jsp be generated into the associated .class file. For full details, see JSR45 – Debugging Support for Other Languages.
