I am using data source explorer in eclipse. the connection is setup and now I want to use it in the normal Java file. I have used the same datasource explorer in a JSP file.
As per this article under the web project section I have tried doing the same.
I tried creating a datasource object as per this Java code
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/mysqltest");
con = ds.getConnection();
but it throws an exception as follows
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context

Setting up the datasource in the datasource explorer has no influence on your server environment.
You will need to define the datasource in Tomcat: either in your context.xml or in the server.xml.
you have to configure your JNDI properties for this datasource properly.
for example: if you are using JBOSS app server then it can be done in db2-ds.xml file.

I have a running ejb in Jboss.
Jboss Port: 8080. I can access it using an application which runs in JBOSS.
JNDI Properties :
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=jnp://localhost:1099
I am trying to access the same ejb using a Tomcat application. My Tomcat server runs on the port 8180. I am using the same JNDI Properties.
But I am getting the following error while running it:

Do you have the mysql jdbc driver jar on your classpath ??
Class is not accessible to JVM java.lang.ClassNotFoundException, please make sure driver jar file is added in your build path.
Class is not accessible to JVM java.lang.ClassNotFoundException, please make sure it is added in your tomcat lib folder and restart your tomcat server
Since sometimes mysql jar is no longer a part from tomcat libs so you have to add it manually.
Particulary for mysql driver it's more confortable to add to tomcat libs folder inside of ../web-inf/lib

After searching on google for the Exception which is thrown I could not find any thing relevant.
Can some body point where things are going wrong?
Any help would be greatly appreciated.
Well I have solved the problem.
Issue was with the permissions on directory structure. Tomcat didn't had enough permissions to access the required directory structure. In my case i was getting the error for repository named jackrabbit.reposiory and i had directory structure like jackrabbit/repository.
Once I made sure tomcat has sufficient permissions on these directories(in my case write permission was lacking), things started moving in the right direction.
I am implementing Google Cloud Messaging service for android. I have created a test server which sends push notifications to application users. But the server I have created is generating following error. I am using Java Servlet at server side and have included gcm-server.jar file in project.
Here is the log:

From the javax.servlet.jsp.SkipPageException javadoc:
Since:
JSP 2.0
This particular exception thus suggests that your webapp's /WEB-INF/lib or, worse, the JRE's /lib or /lib/ext is polluted with servletcontainer-specific JSP libraries such as jsp-api.jar or j2ee.jar which originated from a different servletcontainer which supports only an older JSP version.
You should make absolutely sure that you don't have servletcontainer-specific libraries in your webapp's /WEB-INF/lib folder or elsewhere in the runtime classpath which would only get precedence in classloading over the target servletcontainer's (in your case, Tomcat 6.0's) own libraries.
That they're been placed there is a common starters mistake in an attempt to "fix" compilation errors. It has to be solved differently.
