java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log

Lets build a new spring 3 app from maven.

See the maven version is 3.x

set path=c:\mavan\bin
mvn --version

See what are the archetypes are available

E:\workspace>mvn archetype:generate

Now, let’s generate the project

E:\workspace>mvn archetype:generate -DarchetypeGroupId=org.fluttercode.knappsack -DarchetypeArtifactId=spring-mvc-jpa-demo-archetype -DarchetypeVersion=1.1 -DgroupId=com.mycoompany.springapp -DartifactId=my-spring-app -Dversion=1.0-SNAPSHOT -DinteractiveMode=false

Now you can see a new folder my-spring-app is created

E:\workspace>cd my-spring-app

Convert the project as a Eclipse project and take a coffee break

E:\workspace\my-spring-app>mvn eclipse:eclipse

To instruct Eclipse about mvn, do the following. e:\workspace is my Eclipse workspace

E:\workspace\my-spring-app>mvn -Declipse.workspace=e:\workspace eclipse:add-maven-repo

Import my-spring-app to eclipse and publish to Weblogic.

weblogic.application.ModuleException: java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)

Solve this by replacing the sl4j version to the one compatible with weblogic. For me it is 1.6.1

java.lang.NoSuchMethodError while starting tomcat 7 from Eclipse

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.

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

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.

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

Integrating tomcat 6.0 and Eclipse europa

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.

Register Tomcat with Eclipse

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!
