Diagnose failed deployment

I have to deploy an EAR archive corresponding to a Java EE application in a client's WebLogic server. I have full access to Enterprise Manager but I'm not allowed to deploy through it—instead, I need to invoke a web service that triggers a home-brew shell script. I can see its source code: it first attempts to undeploy the app and (no matter the result) then attempts to deploy the uploaded EAR; each task call a Python script and that's where I lose track. I believe actual work is eventually done by Java libraries from WebLogic Scripting Tool.
The problem is that I'm not getting any error code or message but the application stubbornly remains in its previous release. I'm positively sure there's nothing wrong with the EAR. I've recompiled everything several times and it deploys successfully to the staging server (where I do use EM).
Is there any log file to be found either in Enterprise Manager or Administration Console?

Connecting application built in Tomcat server with application built in Windows server

I have an application built in Tomcat server(Java) and another application built in Windows server(Dot net). I want to connect tomcat with windows as i want to run both the module in one application with one database. Please help me with
Process to connect
2.If there are no ways to connect, then help me with the process to convert windows server to tomcat.
Thanks

In your case, the most straightforward solution would be to expose a rest API on the .net component and call this API from the tomcat component.

How can i change deployed application to webserver from application server?

I am having a web application which is deployed in oracle weblogic application server. After getting analysed, i found that there is no need for application server(atleast for this application), i am in need to deploy this application into the oracle weblogic web server.
can anyone help on this, how can i change deployed application to webserver from application server ?
Or in a different words, i can say how can i migrate my application deployment from oracle weblogic application server to oracle weblogic web server ?
I am using weblogic 10. and Maven to build the application
About the application, it is using Apache axis, webservices, jsf, and few java classes.
Thanks in advance!

I've recently migrated one application from WAS to tomcat
The approach i followd is.
Identify and remove all the WL specific dependencies / jars (that you may not need of)
Change the build script to generate .war instead of .ear
deploy the generated .war to any servlet container/ webserver
with your specs (axis,ws,jsf) you dont need a .ear but .war will do.
if you are using ant modify your build script, i'd suggest go for maven for better dependency management

building of top of the answer by #TechExchange
even for Jboss, you still need to analyze the application to remove all WL specifics.
Ex: Descriptors for EJB's MDB's and so on.
with JBOSS you can still use the ear format.
A quesiton, you had mentioned that because you found that the application doesn't need a app server you decided to migrate it to web server, now with JMS in the picture do you still need to move?

how to deploy struts2 eclipse web application on remote server

I want to check deploying procedure of my struts2 web application developed using eclipse juno on local tomcat server. I want to deploy it to a remote host like 000webhost. Can you provide me any information how to do that?
well, I run my application by typing
http://localhost:8080/Struts2starter/
on browser I want to run it by typing
http://myapp.com/Struts2starter
like something on browser. I wanted to know how to do it.

I don't believe you can deploy a Java application in 000webhost. For example, you can deploy on Google App Engine. Here is an example of how to do that: http://www.mkyong.com/google-app-engine/google-app-engine-struts-2-example/

It depends on server in question. Most servers provide some kind of remote deployment using manager applications / rmi connectors / whaever else exitic means , and eclipse can work with most of them. But of course it needs to be configured on both sides in order to work. Be more specific about your server config, and you will surely get proper answer

Deploying to a Tomcat server which is already running outside of IntelliJ IDEA

I have installed Tomcat server on my PC and I have added it as a service in Windows. So now it starts each time I boot my computer. Now, in IntelliJ I have configured an application server, and that is my Tomcat server, however when trying to "run" the application it says that the port is already in use....and it is ofcourse since Tomcat is started on boot. Is it possible that IntelliJ deploys to the already running Tomcat server instead of trying to start again?

If you want to deploy to Tomcat started outside of IDEA, use the Tomcat Remote Run/Debug configuration type.
The difference of the Remote configuration is that it doesn't start the server, ensure you create Remote configuration, not Local:
It's possible to update application without restarting the server, refer to the Updating Applications on Application Servers help section.

You can use Jrebel plugin. It will be helpful to update your application without restarting your server.
