Re: java.lang.NullPointerException at org.apache.jasper.JspCompilationContext.getTldResourcePath(JspCompilationContext.java:536) when starting Embedded Tomcat Instance
Hi, I manually set the TldCache in my context and get rid of the NullPointerException.

I can't figure out the reason to get this NullPointerException.
Can someone help me out?
If we knew which version of Tomcat 8 you were using, someone could
look
at the relevant source code to try to figure out what was going
on.
I'm using tomcat version *8.0.20*
Browse to the sourcecode of v8.0.20 of tomcat here:
public TldResourcePath getTldResourcePath(String uri) {
return getOptions().getTldCache().getTldResourcePath(uri);
}
Thanks for the quick response
Obviously either getOptions() or getTldCache() is returning null.
I debug the code as you suggest and found that getTldCache() is null.
In the code As I understand there are 2 point which set the *tldCache*
variable
one is the setTldCache() method and other is
public static TldCache getInstance(ServletContext servletContext) {
if (servletContext == null) {
throw new IllegalArgumentException(Localizer.getMessage(
org.apache.jasper.compiler.TldCache.servletContextNull));
}
return (TldCache)
servletContext.getAttribute(SERVLET_CONTEXT_ATTRIBUTE_NAME);
}
If you can attach a debugger try to see whether the code below is
invoked:
org.apache.jasper.servlet.JasperInitializer.onStartup(SetClass?,
ServletContext) {
.
context.setAttribute(TldCache.SERVLET_CONTEXT_ATTRIBUTE_NAME,
new TldCache(context,
scanner.getUriTldResourcePathMap(),
scanner.getTldResourcePathTaglibXmlMap()));
}
I have checked that as well. But that method didn't get hot when I'm
debugging the source.
what could be the reason?
You wrote that you are running an embedded Tomcat. Is that true?
In Tomcat 8, Jasper initialization is implemented as a standard
ServletContainderInitializer (check Servlet specification).
So you should ensure
that org.apache.jasper.servlet.JasperInitializer.onStartup is invoked
during web app startup
Could someone tell me how can I make sure that this method get call during
the web app startup?
You didn't tell us whether you are embedding Tomcat or not.
If you are embedding it which jar files from Tomcat distribution you are
using etc.
You can start debugging
with org.apache.catalina.startup.ContextConfig.webConfig()
- processServletContainerInitializers(sContext);

Yes I'm embedding tomcat version 8.0.20
If you are embedding it which jar files from Tomcat distribution you are

I'm using following tomcat jars
- tomcat-embed-core
- tomcat-embed-jasper
- tomcat-websocket-api
- tomcat-embed-websocket
- tomcat-jasper
You can start debugging
with org.apache.catalina.startup.ContextConfig.webConfig()

from this 2 methods I couldn't find any point that setTldCache() is been

one is the setTldCache() method and other is
public static TldCache getInstance(ServletContext servletContext) {
if (servletContext == null) {
throw new IllegalArgumentException(Localizer.getMessage(
org.apache.jasper.compiler.TldCache.servletContextNull));
}
return (TldCache)
servletContext.getAttribute(SERVLET_CONTEXT_ATTRIBUTE_NAME);
}
If you can attach a debugger try to see whether the code below is invoked:
org.apache.jasper.servlet.JasperInitializer.onStartup(SetClass?,
ServletContext) {
.
context.setAttribute(TldCache.SERVLET_CONTEXT_ATTRIBUTE_NAME,
new TldCache(context, scanner.getUriTldResourcePathMap(),
scanner.getTldResourcePathTaglibXmlMap()));
}
Regards,
Violeta
from this 2 methods I couldn't find any point that setTldCache() is been
used. So I think getInstance() is the method that is been used.
Should I manually set the value o tldCache?
Thanks
Regards

I can't figure out the reason to get this NullPointerException.
Can someone help me out?
If we knew which version of Tomcat 8 you were using, someone could look
at the relevant source code to try to figure out what was going on.
I'm using tomcat version *8.0.20*
Browse to the sourcecode of v8.0.20 of tomcat here:
public TldResourcePath getTldResourcePath(String uri) {
return getOptions().getTldCache().getTldResourcePath(uri);
}
Thanks for the quick response
Obviously either getOptions() or getTldCache() is returning null.
I debug the code as you suggest and found that getTldCache() is null.
In the code As I understand there are 2 point which set the *tldCache*
variable
one is the setTldCache() method and other is
public static TldCache getInstance(ServletContext servletContext) {
if (servletContext == null) {
throw new IllegalArgumentException(Localizer.getMessage(
org.apache.jasper.compiler.TldCache.servletContextNull));
}
return (TldCache)
servletContext.getAttribute(SERVLET_CONTEXT_ATTRIBUTE_NAME);

The lines you want look like this:
535 public TldResourcePath getTldResourcePath(String uri) {
536 return getOptions().getTldCache().getTldResourcePath(uri);
537 }
Obviously either getOptions() or getTldCache() is returning null.
Reverse engineer the source to find out which, or stop the code in a debugger.

org.apache.jasper.servlet.JasperInitializer.onStartup(SetClass?,
ServletContext) {
.
context.setAttribute(TldCache.SERVLET_CONTEXT_ATTRIBUTE_NAME,
new TldCache(context,
scanner.getUriTldResourcePathMap(),
scanner.getTldResourcePathTaglibXmlMap()));
}
I have checked that as well. But that method didn't get hot when I'm
debugging the source.
what could be the reason?
You wrote that you are running an embedded Tomcat. Is that true?
In Tomcat 8, Jasper initialization is implemented as a standard
ServletContainderInitializer (check Servlet specification).
So you should ensure
that org.apache.jasper.servlet.JasperInitializer.onStartup is invoked
during web app startup
Thanks for the quick response. Could you please tell me how can I do so?
Thanks
