Tomcat started in Eclipse. But application is not started

Posted on September 19, 2019 by Pandian Ramaiah

This is a strange problem after I migrated from old version of STS to STS4.

Removed the server tomcat and added again
Removed few .props files from workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings.
changed the server locations in Server overview screen

Nothing helped except Maven Build.. Still Open. I’ll update if I have a solution later.

Eclipse tomcat does not start – May be locked by another process.

Posted on January 1, 2019 by Pandian Ramaiah

Happy Western New Year 2019!

I had a single spring web project. It became too big over the day. I had to split it up into multiple reusable projects so that I can build APIs. After I split it, Tomcat refused to start with the following error.


Publishing failed with multiple errors
Could not delete D:/Pandian/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/crm-upload/WEB-INF/lib. May be locked by another process.
Could not delete D:/Pandian/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/crm-upload/WEB-INF. May be locked by another process.

I tried to clean work folder, It doesn’t work. I did the following sequence to resolve this.

Remove the tomcat server from eclipse server tab
Restart Eclipse
Add a new tomcat server
Start the project

No Spring WebApplicationInitializer types detected on classpath

Posted on December 7, 2017 by Pandian Ramaiah

Wah, what a stupid error it was!

My Spring web app, which was running smoothly, refused to start. I don’t find any logs in log4j or tomcat log. Only clue I had was –

No Spring WebApplicationInitializer types detected on classpath

Here is how I solved it –

Stop the tomcat
Clean and build all eclipse projects
Goto server tab and select the tomcat server. Press clean. Press clean work directory.
Right click on the tomcat and remove it.
Delete the tomcat from the eclipse run times
Add tomcat server to the eclipse servers again
Start the application

Integrating Apache and Tomat with mod_jk

Posted on January 13, 2016 by Pandian Ramaiah

This post is a continuation of my previous post. In this post I’ll tell you what I did to access my tomcat apps via Apache.

All the files you edit here are very crucial. Take a backup and make a note of the changes you do. Otherwise, it may goof your Apache configuration.

Installing mon-jk library

$ sudo apt-get install libapache2-mod-jk

Make sure the AJP redirect port is enabled on tomcat/config/server.xml

Create a new worker file

sudo vi /etc/apache2/workers.properties

# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009

Reconfigure jk.conf

Change the JkWorkersFile property to /etc/apache2/workers.properties

sudo vi /etc/apache2/mods-available/jk.conf

# JkWorkersFile /etc/libapache2-mod-jk/workers.properties
JkWorkersFile /etc/apache2/workers.properties

Configure the URL Apache should pass through the Tomcat

sudo vi /etc/apache2/sites-enabled/000-default

and add the line starts with JKMount in your configurtation

<VirtualHost *:80>
…………………………………
…………………………………
JkMount /gplus* worker1
</VirtualHost *:80>

Restart apache

I found http://<apacheIP>/gplus worked.

java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

Posted on May 12, 2012 by Pandian Ramaiah

java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

This is another nasty exception, when upgrading the tomcat version. Add the tomcat-juli.jar from tomcat\bin to classpath. It should get resolved

Apache – Tomcat connector in Windows

Posted on October 10, 2011 by Pandian Ramaiah

This is another interesting assignment completed today. Though our CRM portal is no so busy, we want to in a robust infra. There are series of new releases available kn the market. JDK 7, Tomcat 7 etc. Previously the application was using tomcat itself as a web server. This is a risky situation since I expose the complete applivation to public. Hence I have installed the apache as web front-end and tomcat 7 as middleware.

Here is the procedure:

mod_proxy_ajp would be the easiest to use if you are using Apache 2.2. It is part of the Apache distribution so you don’t need to install any additional software.

In your httpd.conf you need to make sure that mod_proxy and mod_proxy_ajp are loaded:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

Then you can use the ProxyPass and ProxyPassReverse directives as follows:

ProxyPass /portal ajp://localhost:8009/portal
ProxyPassReverse /portal ajp://localhost:8009/portal

As simple as that.

java.lang.NoSuchMethodError while starting tomcat 7 from Eclipse

Posted on September 7, 2010 by Pandian Ramaiah

My tomcat 7 server is starting and working fine by itself. When I stop it and try to start from Eclipse, it gives a NoSuchMethodError which aborts the server starting.

java.lang.NoSuchMethodError: org.eclipse.wst.server.core.model.ServerBehaviourDelegate.getTempDirectory(Z)Lorg/eclipse/core/runtime/IPath;

somebody is getting same error, but still not resolved. http://www.eclipse.org/forums/index.php?t=msg&goto=557431&S=432a9edd157438a3661ca16edfe4a4ab

I have raised a bug report to eclipse. Lets see.

>>>

I just got an update from Eclipse Bugzilla

Your Build Identifier indicates you are using Eclipse 3.5, which only works
with WTP 3.1.x. WTP 3.2.x, which includes the new Tomcat 7.0 support, requires
Eclipse 3.6.x. Running WTP 3.2.x with Eclipse 3.5.x is not supported. You
will have to install Eclipse 3.6 since upgrading 3.5.x to 3.6 is not supported.
Once you have Eclipse 3.6 with WTP 3.2.x installed (using the Java EE package
is the easiest) you can create a new workspace and import your existing
projects, or you can simply open old workspace. If you open the old workspace
with Eclipse 3.6 and WTP 3.2.x, using that workspace with Eclipse 3.5 and WTP
3.1.x is not supported.

Since Eclipse 3.5.x and WTP 3.2.x is not a supported combination, I’m marking
this bug as invalid.

Upgrade karega!

Target runtime Apache Tomcat v6.0 is not defined

Posted on September 7, 2010 by Pandian Ramaiah

I was upgrading the tomcat in my eclipse from version 6 to 7. Servers were added, old servers were removed. Tomcat 6 installed. But the server is not starting because of the following error.

Target runtime Apache Tomcat v6.0 is not defined. <project name> Unknown Faceted Project Problem

It keeps my old server entry for the project.

We need to right click on the project, properties and Targeted Runtimes. Uncheck the old entry and enable the new entry. This should solve this error.

Targeted Runtimes

Still server is facing some other issue. Need to check up.

Way to Struts 1.2 DataSource

Posted on November 23, 2008 by Pandian Ramaiah

hurray

Today I had downloaded struts 1.2.7 and tried to write an application. (I know I am selecting a bit old.) I configured the datasource in struts. Alas. When I tried to start my server, tomcat 6.0, I got the error saying "java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource". With Googling I found struts-legacy.jar need to downloaded and copied to lib folder of Tomcat. (I couldnt get the recent version of struts-legacy. I found something in archive). Happily restarted the server. I saw java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool.. oof.. again I need to download commons-dbcp-1.2.2.jar and commons-pool.jar.

My search come to an end 🙂 It is working fine now.

Integrating tomcat 6.0 and Eclipse europa

Posted on April 20, 2008 by Pandian Ramaiah

Till now I was using eclipse and tomcat separately, I was not that much serious about deployment, generally I goto the web application folder and edit/compile there itself. I know tomcat can be integrated with Eclipse, but I never tried. Today I have no other go. I need to do it. Here are the steps.

Select Window>Preferences

select the server you want to add, here we are adding tomcat 6.0 available under apache node

fill the necessary details

Here you can see the server is added to the list

You can see a new Project called Servers added to the Project explorer, If it is already there, the server might have been appended to the list

now open the corresponding web project to be deployed and start running it (ctrl + F11). Select Run on Server option

specify the server in which the application is to be deployed.

Move the projects to be deployed to the server. Here we have only one.

Thats it. done! see the web page is getting loaded!
