How do I install a 3rd party JAR file to my tomcat web application?
I have placed it in every folder I can think of, and am referencing it like:
import com.google.api.translate;
Is there a particular folder? I have tried WEB_INF/lib
If all apps on Tomcat need that JAR, the place to put it would be /lib if you're using Tomcat 6.x or higher and /server/lib if it's version 5.x or lower.
If only your app needs a 3rd party JAR, put it in WEB-INF/lib.
I hope you're packaging your app as a WAR file.

I'd recommend reading a bit more about Tomcat and CLASSPATH before you proceed.
import com.google.api.translate;
This doesn't look like proper Java to me. Shouldn't that be:
import com.google.api.translate.*;
What is the name of the JAR containing those classes? Where did you find it?
Looks like you want to use Google's translate API somehow.

I want to migrate running java application to Jdev12c. Can i use all the jar used in Eclipse as it is. I have eclipse related jars also i.e.
org.apache.commons.logging-1.0.4.v201101211617.jar
org.eclipse.persistence.core-2.5.0-RC2.jar
org.eclipse.persistence.jpa-2.5.0.jar
org.eclipse.persistence.oracle-2.5.0.jar
can i use these all jars in Jdev directly. and also apache logger file will work in Jdev or not. also do i need to change something in classes and code?
I have folders in the application and which have files. I am also using .property file. so can i directly use this all.
JDeveloper has ability to import code from WAR file or a Maven project (import menu under file menu).
Or you can just create project from existing code.
You'll need to point to the jars in the project properties->libraries and class path
I am trying to use postgres on a EJB in a EAR, but i keep getting the error:
java.lang.ClassNotFoundException: org.postgresql.driver
so my app is not finding the jar. According to what I saw here: How to use 3rd party libraries in glassfish?, I should put the jar on either glassfish3/glassfish/domains/domain1/lib/ext or glassfishv3/glassfish/domains/domain1/lib, I tried both and is not working.
I was also not sure of something, should I add the jar to that folder and then reference the build path (using netbeans) of my app to the jar on that folder? or should I omit this step?
Anyhow, I tried both, referencing it and not doing it (only adding the jar to the folder in glassfish) and is not working.
So, how can I add an external jar to my application (EAR) that is put on a glassfish cluster?
I have a pretty basic Java web application (created using Eclipse openshift plugin). The app runs fine on the OpenShift server. Now I need to use an external JAR library for JSON parsing and creation in Java. I can't understand my way around how to add that JAR to openshift server.
I went to project properties>>BuildPath>>Add external JAR. While that does import the JAR, it does not work on openshift server and gives error relating to that file's import (NoClassDefFound, I guess). Could you tell me how to import external jars into openshift project?
Since we use Maven for the build process, all you have to do is add it as a dependency in your pom.xml
Here is an example that adds a mongo driver
https://github.com/thesteve0/openshift-mongo-spatial-jee6/blob/master/pom.xml
Look under the dependencies tag
You can add the jar as a dependency in your pom.xml file. This will cause the jar to be included in your war. If the jar is not available in a public maven repo, please see here: http://www.billdecoste.net/?p=16

You might want to take a look at this link from OpenShift itself.
It includes information about adding jars with and without maven dependencies.
I have a web application which consist of JSP pages, Servlet and Consumes Web Services.
It also references apache axis and excel libraries.
Now I want to deploy my application directly in Weblogic server
How do i do that.Whcih archive shud i make WAR or JAR??
ALso how to ensures that it covers all the referenced libraries.
I have made my application in Jdeveloper, but I dont want to deploy it using Jdevelper..
I would package my solution as a .war file, containing all dependent .jar files.
That way your solution is self-contained. You can deploy to an app server containing other apps with their own versions of your libraries (dependent or developed). If you put the dependent jars directly into the app server (as you can do), then you're forcing those versions on all applications deployed, and that could well cause you grief.
The downside is that your developed .war file can become sizable. It's not normally a major problem, and I wouldn't worry about it until it's identified as an issue.
A JAR-file cannot contain a JAR-file, so that option is out. Since you mention JSPs and servlets a WAR would seem the appropriate option, although an EAR with a WAR and several JARs could also be a way forward...
Cheers,
Consider a WAR with your JAR files in WEB-INF/lib. Or, create an EAR with APP-INF/lib folder.
I really apologize if this is a silly question.
I have a tomcat server running on a unix machine. I want to use the HTTPClient library. Does it come pre-bundled with tomcat or do you need to install it?
If people say to just add it to your class path. Should I download the source or the binary from here:
http://hc.apache.org/downloads.cgi
Once downloaded is there a way to auto install it using a .tar.gz as I think I have done this in the past. If not is it just a case of putting the folder on the drive and adding it to the classpath?
TIA
Each web application is supposed to package its own dependencies inside the deployable WAR file. It is an ill-advised practice to extend Tomcat's global library with any library an application might need.
On the WAR building front, the common practice you should stick to is not to manage dependencies on your own; it quickly turns into a nightmare. Configure your project with Maven , which will both manage the dependencies and build the WAR for you.
Just look for httpclient....jar file in the Tomcat directory. If there is none there, then put it inside the lib directory :)
You should download the appropriate jar file. It contains portable library code. Once placed in the classpath, Tomcat will find it. Tomcat directory has a lib subdirectory. This is global classpath part for all web applications.
