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. But now I'm getting following exception org.apache.jasper.JasperException: The absolute uri: > http://tiles.apache.org/tags-tiles cannot be resolved in either web.xml > or the jar files deployed with this application > at > org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:55) > at > org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:277) > at > org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:75) > at > org.apache.jasper.compiler.TagLibraryInfoImpl.generateTldResourcePath(TagLibraryInfoImpl.java:240) > at > org.apache.jasper.compiler.TagLibraryInfoImpl.(TagLibraryInfoImpl.java:124) > at org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:411) > at org.apache.jasper.compiler.Parser.parseDirective(Parser.java:469) > at org.apache.jasper.compiler.Parser.parseElements(Parser.java:1430) > at org.apache.jasper.compiler.Parser.parse(Parser.java:139) > at > org.apache.jasper.compiler.ParserController.doParse(ParserController.java:227) > at > org.apache.jasper.compiler.ParserController.parse(ParserController.java:100) > at org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:199) > at org.apache.jasper.compiler.Compiler.compile(Compiler.java:356) > at org.apache.jasper.compiler.Compiler.compile(Compiler.java:336) > at org.apache.jasper.compiler.Compiler.compile(Compiler.java:323) > at > org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:570) > at > org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:356) > at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:396) > at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:340) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:725) > at org.wso2.carbon.ui.JspServlet.service(JspServlet.java:175) > at org.wso2.carbon.ui.TilesJspServlet.service(TilesJspServlet.java:80) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:725) > at > org.eclipse.equinox.http.helper.ContextPathServletAdaptor.service(ContextPathServletAdaptor.java:37) > at > org.eclipse.equinox.http.servlet.internal.ServletRegistration.service(ServletRegistration.java:61) > at > org.eclipse.equinox.http.servlet.internal.ProxyServlet.processAlias(ProxyServlet.java:128) > at > org.eclipse.equinox.http.servlet.internal.ProxyServlet.service(ProxyServlet.java:68) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:725) > at > org.wso2.carbon.tomcat.ext.servlet.DelegationServlet.service(DelegationServlet.java:64) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:291) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) > at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:239) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) > at > org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:721) > at > org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:466) > at > org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:391) > at > org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:318) > at > org.eclipse.equinox.http.servlet.internal.RequestDispatcherAdaptor.forward(RequestDispatcherAdaptor.java:30) > at > org.eclipse.equinox.http.helper.ContextPathServletAdaptor$RequestDispatcherAdaptor.forward(ContextPathServletAdaptor.java:362) > at > org.apache.tiles.servlet.context.ServletTilesRequestContext.forward(ServletTilesRequestContext.java:198) > at > org.apache.tiles.servlet.context.ServletTilesRequestContext.dispatch(ServletTilesRequestContext.java:185) > at > org.apache.tiles.impl.BasicTilesContainer.render(BasicTilesContainer.java:419) > at > org.apache.tiles.impl.BasicTilesContainer.render(BasicTilesContainer.java:370) > at org.wso2.carbon.ui.action.ActionHelper.render(ActionHelper.java:52) > at org.wso2.carbon.ui.TilesJspServlet.service(TilesJspServlet.java:101) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:725) > at > org.eclipse.equinox.http.helper.ContextPathServletAdaptor.service(ContextPathServletAdaptor.java:37) > at > org.eclipse.equinox.http.servlet.internal.ServletRegistration.service(ServletRegistration.java:61) > at > org.eclipse.equinox.http.servlet.internal.ProxyServlet.processAlias(ProxyServlet.java:128) > at > org.eclipse.equinox.http.servlet.internal.ProxyServlet.service(ProxyServlet.java:68) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:725) > at > org.wso2.carbon.tomcat.ext.servlet.DelegationServlet.service(DelegationServlet.java:64) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilt

Thanks for response and I'm Sorry for missing the info in previous mail.
Yes I'm embedding tomcat version 8.0.20

I'm using following tomcat jars
- tomcat-embed-core
- tomcat-embed-jasper
- tomcat-websocket-api
- tomcat-embed-websocket
- tomcat-jasper

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);

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.

I have checked that as well. But that method didn't get hot when I'm

what could be the reason?

If you can attach a debugger try to see whether the code below is invoked:
org.apache.jasper.servlet.JasperInitializer.onStartup(Set>,
ServletContext) {
.
context.setAttribute(TldCache.SERVLET_CONTEXT_ATTRIBUTE_NAME,
new TldCache(context, scanner.getUriTldResourcePathMap(),
scanner.getTldResourcePathTaglibXmlMap()));
}

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);
}
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

Browse to the sourcecode of v8.0.20 of tomcat here:
https://svn.apache.org/viewvc/tomcat/tc8.0.x/tags/TOMCAT_8_0_20/java/org/apache/jasper/JspCompilationContext.java?view=markup
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.

Graham

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.
Hint: Tomcat is open source. You can look at the source code too.

Hi All,
I'm in the process of migrating embedded tomcat application from Tomcat 7
to Tomcat 8.
When I'm trying to start the embedded instance I'm getting a
