Thread-47 java.lang.NullPointerException
hi , I click and browse through some of the features accessing applets in the application, quite often I get the following Null Pointer Exception in the java console. I really do not understand the cause of the problem.I am using tomcat4.1. the error is : Exception in thread Thread-47 java.lang.NullPointerException at sun.plugin.util.GrayBoxPanel.paint(Unknown Source) at sun.plugin.util.GrayBoxPanel.setImage(Unknown Source) at sun.plugin.util.GrayBoxPanel.setCustomImage(Unknown Source) at sun.plugin.util.GrayBoxPainter.getGrayBoxPanel(Unknown Source) at sun.plugin.util.GrayBoxPainter.paintGrayBox(Unknown Source) at sun.plugin.util.GrayBoxPainter.repaintGrayBox(Unknown Source) at sun.plugin.util.GrayBoxPainter.access$000(Unknown Source) at sun.plugin.util.GrayBoxPainter$1.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Next time when I repeat the same scenario I get the following: Exception in thread Thread-182 java.lang.NullPointerException at sun.plugin.util.GrayBoxPanel.paint(Unknown Source) at sun.plugin.util.GrayBoxPanel.setImage(Unknown Source) at sun.plugin.util.GrayBoxPanel.setCustomImage(Unknown Source) at sun.plugin.util.GrayBoxPainter.getGrayBoxPanel(Unknown Source) at sun.plugin.util.GrayBoxPainter.paintGrayBox(Unknown Source) at sun.plugin.util.GrayBoxPainter.repaintGrayBox(Unknown Source) at sun.plugin.util.GrayBoxPainter.access$000(Unknown Source) at sun.plugin.util.GrayBoxPainter$1.run(Unknown Source) at java.lang.Thread.run(Unknown Source) I do not really know if it is really a Tomcat issue or not..

Re: Thread-47 java.lang.NullPointerException
Applets are a client side technology not a server side one. This means that applets are executed by browsers, not by Tomcat. As far as Tomcat is concerned, an applet is just a file delivered to the browser. This is a bug in the applet you are using or possibly an error in the way you are using it. Also, if you look at the stack trace, it is all from the sun.plugin.util.GrayBoxPanel class which is not a Tomcat class.

Re: java.lang.NullPointerException in tomcat 5.5.4
In your login.jsp you're calling the dispatch method of gnu.beanfactory.servlet.Dispatcher and most likely passing it null as an argument. I don't know anything about this beanfactory, so I can't say much more at the moment. -Original Message- From: ssk 2001[EMAIL PROTECTED] To: tomcat-user@jakarta.apache.org Date: Fri Dec 31 00:08:20 PST 2004 Subject: java.lang.NullPointerException in tomcat 5.5.4 I installed tomcat 5.5.4 ,jdk1.5 and beanfactory 1.0.1.

Brandon, the scriptlet in your jsp gets your server's cookies from the client:
Cookie[] cookies = request.getCookies();
but on the initial request, there are no cookies set by your server on any
given client, so getCookies() returns null in accordance with the servlet
spec. That triggers a NPE when you try to process the cookies later:
for (int i=0; icookies.length; i++) {
...
}
Put an if statement around your for loop to check if cookies is null or
not and that should fix your problem.

interesting java.lang.NullPointerException error when first viewing an index.jsp page - refresh once and page loads correctly
This may be a rather easy issue but with my limited knowledge of Tomcat - I thought one of you more qualified folks would have a solution.

Jeff,
When you said importing the bean class at the top of the page, Is it
like that in the JSP page:
% page import=com.imedge.admin.IMDbFamilyBean %

java.lang.NullPointerException at TldLocationsCache.processJars when running Tomcat 4.x built from sources
Dear Collegues ! I tried to build Tomcat 4.0.3 and then 4.1 (from cvs) and every time failing the same way (!) when running the built project.

Please point me into the right direction. I know something went wrong. But what ? Has anybody similar problems ? There were some inconsistences: The downloaded jakarta-tomcat-connectors does not contain SystemLogHandler.class - I found it on the one downloaded from cvs. Also there were no # - Commons Logging, version 1.0.1 or later - in the location pointed in build.properties.sample file: commons-logging.loc=http://jakarta.apache.org/builds/jakarta-commons/release /commons-logging/v1.0.1/commons-logging-1.0.1.tar.gz I have found them also somewhere among cvs downloaded files. sincerely Olek Poznan, Poland System : w2k JDK: 1.4.0 ANT: 1.4.1 Tomcat 4.0.3 - source download Tomcat 4.1 from cvs javax.servlet.ServletException: Servlet.init() for servlet jsp threw exception at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:94 7) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:656) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.ja va:214) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.ja va:191) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2350) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:180 ) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve. java:170) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:641) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:171 ) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:641) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java :174) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.coyote.tomcat4.CoyoteAdapter.service(CoyoteAdapter.java:223) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:405) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConne ction(Http11Protocol.java:380) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:508) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.jav a:518) at java.lang.Thread.run(Thread.java:536) root cause java.lang.NullPointerException at org.apache.jasper.compiler.TldLocationsCache.processJars(TldLocationsCache.j ava:203) at org.apache.jasper.compiler.TldLocationsCache.(TldLocationsCache.java:139) at org.apache.jasper.EmbededServletOptions.(EmbededServletOptions.java:350) at org.apache.jasper.servlet.JspServlet.init(JspServlet.java:265) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:91 9) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:656) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.ja va:214) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.ja va:191) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2350

Have a look at line 123 in the generated source file _0002fjsp_0002fNew_0002fdyeing_0002ejspdyeing_jsp_0.java to see which statement causes the exception. If you found the region and can't see the error, try to reduce the page to the bare minimum that reproduces the error and post the source for that. -Ursprüngliche Nachricht- Von: Naeem Malik [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 17.

If you found the region and can't see the error, try to
reduce the page to the bare minimum that reproduces the
error and post the source for that.
I have seen a similar problem which I posted to tomcat dev. The
generated source code is
...
} finally {
if (out != null) out.flush();
if (_jspxFactory != null)
_jspxFactory.releasePageContext(pageContext);
}
...
and the error came from the releasePageContext method which tried to do
something with pageContext. It seems quite repeatable if tomcat is run
with security. e.g. standard 3.2 examples/numguess. My case is when I
have access controls turned on and am doing authentication. No answer
in the dev list. This always occurs if you have no permissions when
compiling the login page which is the result of a redirection from the
protected resource. This is in 3.2.2b4
Seems to be a general problem when run with security.

RE: Handler Thread Problem : java.lang.NullPointerException
How
about trying this for your index.jsp:
--- Begin Code --
!-- Put your imports here
--
%@ page import="java.io.*,java.util.*
%
html
body
% response.sendRedirect
("http://212.100.172.240/park/index.jsp");
%
/body
/html
!-- End Code --
Just a
thought

HANDLER THREAD PROBLEM : java.lang.NullPointerException
Hi I've got my website uprunning http://www.be-day.com and it is completely running using Tomcat. We are selling domainnames for .BE (Belgium) Everything works fine but our latest feature : URL Forwarding. Tomcat always reports : HANDLER THREAD PROBLEM : java.lang.NullPointerException We configured apache to take any unknown URL entering to one specific virtual host which has an index.jsp file ready. In case the customer configured URL Forwarding, I query the database and turn the index.jsp page into a forwarding page to forward to the configured URL. If no URL Forwarding is configured by the customer in the database, I just turn the index.jsp page into a "parked domain" page. If I access the index.jsp page directly I get no problems. I just type : www.myserver.be/park/index.jsp and Tomcat responds properly. But if I enter with www.mycustomerdomain.be, then apache takes this URL to www.myserver.be/park/index.jsp but Tomcat responds with HANDLER THREAD PROBLEM : java.lang.NullPointerException The parked pages and the rest of the website run in the same Tomcat context. I already tried to fix this by separating the contexts. No luck. Thx for your time patience, Pls CC: [EMAIL PROTECTED] Koen
