RE: [E] Re: Cannot get a connection, pool error Timeout waiting for ideal object

[Halder, Arpan [ITSUS Non J]]

Hi Chris,

Thank you for your reply!!

Please note that we tried to make changes to the contex.xml file located under 
the conf directory of tomcat.

However, on restarting the tomcat server after making changes to values in 
these, the application is throwing a 404: Resource not Found error. The tomcat 
server is up and running but on hitting the application URL, we are getting the 
404 error.

We even tried restoring the context.xml file to its original values but that 
did not seem to  make a difference.

Can you  please advise what steps we need to follow in  order to fix this issue?

Thanks and Regards,
Arpan

That is the wrong file. The file conf/context.xml contains the defaults for 
every application deployed onto that Tomcat server. Your application should 
have its own, separate context.xml file in the META-INF directory.

Okay.

Everything looks okay up there. You might want to add:

   logAbandoned="true"

This will log places in your code where you have resource leaks.

Those are the deployment descriptors for the host-manager and the manager 
applications respectively. Do not modify those files.

Re: Tomcat stopped and Debug can't be done in Eclipse

1. On the topic of debugging, see the following page:
https://wiki.apache.org/tomcat/FAQ/Developing

The following two items on that page should be interesting for you:
a) "Official Eclipse IDE Web Tools FAQ for Tomcat"

with links to Eclipse documentation

b) "How do I configure Tomcat to support remote debugging?"

This is for the use case when you start Tomcat separately and attach a
debugger to an already running Tomcat.


2. On a topic of simply running Tomcat (not debugging), official
documentation is "RUNNING.txt" file.

There is also
http://tomcat.apache.org/tomcat-8.5-doc/setup.html

Environment variables used by launch scripts are documented in a
comment at the top of those scripts (catalina.bat, catalina.sh).

3. When Tomcat starts, its actual arguments are printed by
VersionLoggerListener.

You can see them in your previous e-mail, Search for "Command line argument"
http://markmail.org/message/tgymk3r43ox5ggps

> Cos I can't proceed with any debugging at all as in run the green button : 
> Please see this attachment at https://imgur.com/OQLyJFb

4. In your image I see that your Tomcat is not running

(The "Console" view at the bottom says "". The "Servers"
view says "[Stopped, Synchronized]".)

How did you start it?

5. My recipe will be:
- In the "Servers" view select the server and deploy you application
onto it (right click -> context menu -> ...)
- Then click the small green "bug" button in the toolbar of this view
(in the small toolbar right above "Servers" view, not the one in the
main toolbar). The server should launch in debug mode.

Random shot in the dark given the minimal date provided :) Does it
look like this:

If so, then your client is sending you requests with unencoded special

I can't answer that without more information. What is throwing the
exception? A stack trace would be helpful.

I keep running into the an IllegalArgumentException at or near startup of
tomcat 8.5 with a bunch of cxf web services deployed and I have no idea
what's causing it. The error message mentions turning on logging at the
debug level.

Question: Assuming i need to edit the logging.properties file, which

 1. How exactly do you start
 Tomcat in debug mode? What instructions
 and
 documentation are you following?

 I think that
 "suspend=y" option is the cause of the behaviour
 that you
 are seeing.
 
 IIRC, with that option Java stops and waits for
 a debugger just after
 JVM launch. I think
 that in Eclipse you can look into "threads"
 view,
 find a running (stopped)
 "main" thread there and hit a green button to
 resume it.
 
Hi Konstantin,

Can you point me some useful resources where I can learn about setting the 
Tomcat launch configuration.

Currently, I have the below inside my arguments :

-Dcatalina.base="C:\Users\Karen.Goh\workspace3\.metadata\.plugins\org.eclipse.wst.server.core\tmp0"
 -Dcatalina.home="C:\Program

 -Djava.endorsed.dirs="C:\Program 
Files\Apache\apache-tomcat-9.0.4-windows-x64\apache-tomcat-9.0.4\endorsed"

Is this the part that is causing Tomcat to just hang ? Or I have missed out 
something I am not aware of.  Kindly highlight please.

Cos I can't proceed with any debugging at all as in run the green button : 
Please see this attachment at https://imgur.com/OQLyJFb

Is there any other changes I need to make since I am also using a maven plug in 
as below :


org.apache.maven.plugins
maven-war-plugin
3.2.0
 

It used to be very easy for me to do debugging and now things are so much 
complicated now.

Re: asgard tomcat application 404

[Simon De Uvarow]

I don't know about Spring, but according to your exception, and my short
experience, could be a database connection issue.

grails.web.context.GrailsContextLoaderError initializing Grails: Error
creating bean with name 'pluginManager' defined in ServletContext resource
*[/WEB-INF/applicationContext.**xml]*: Invocation of init method failed;
nested exception is java.lang.NullPointerException: Cannot invoke method
getAt() on null object

Usually in the context file is where u define the connection pool, and JPA
stuff.
The null pointer exception makes me imagine that a DB connection, or entity
manager, couldn't be created.

Maybe the asgard database was not created as expected by the app?

Hope it helps,

Stream closed error while rendering JSP

[Sergey Zolotarev]

Hello,

I'm trying to debug an exception that sometimes happens when Tomcat
renders a JSP page. I have a custom error page (error.jsp) in a Struts
2 application defined in struts.xml like this:


/error.jsp


Sometimes it fails to render with and Tomcat says that it can't read
the JSP file:

org.apache.jasper.JasperException - Cannot read file: /error.jsp

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:55)

org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:277)
org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:75)
org.apache.jasper.compiler.JspReader.(JspReader.java:122)
...

and the underlying exception is:

org.apache.jasper.compiler.JspReader. Exception parsing file
 java.io.IOException: Stream closed
at 
java.util.zip.InflaterInputStream.ensureOpen(InflaterInputStream.java:67)
at

But error.jsp exists in the .war file, I checked that. How can I
determine what is causing the input stream to get closed?

I would appreciate any help.

Thank you.
