I am new to Nginx and I need your help, According to many forums I understood that all our static pages are stored in Nginx. When there is request comes I have to pass that request to tomcat for data and after response from tomcat response generated. Currently, I have just done that I request directly passed to tomcat and respond to request. but I think that is not solution for performance. So anyone can Help me? Jason You can using proxy_pass mapping to your tomcat server port, for example : if your tomcat port is 8080, your conf/nginx.conf should be configured like this: ... http { ...

DISCLAIMER: I'm relatively new to Linux. I debated putting this on SuperUser or ServerFault because the answer does require an explanation of Linux as a system (and not a specific programming problem), however I'm interested in this from a Java developer's perspective, and I argue that this is a specific problem because where I install GlassFish greatly impacts my Java configuration, and ultimately, app configuration. Not to mention posting this question on those other sites probably won't garnish any attention from a Java developer, more over system admins, who may not know enough about Java

How is gzip compression for Jboss 5.1.0 enabled? Within the tomcat http connector right? I cant remember where this file is stored, server.xml? The file is under server.xml and you are correct in stating that you have to updated the http connector. Following link is info for tomcat, but same applies to JBoss except location of server.xml file. I believe you need to update the server.xml under deploy\jbossweb.sar\ http://viralpatel.net/blogs/2008/11/enable-gzip-compression-in-tomcat.html James Clarke edit jboss\server\default\deploy\jbossweb.sar\server.xml Edit this: <Connector protocol="HTTP/1

Is Tomcat a web server or an application server? BalusC Tomcat is a web server (can handle HTTP requests/responses) and web container (implements Java Servlet API , also called servletcontainer) in one. Some may call it an application server , but it is definitely not an fullfledged Java EE application server (it does not implement the whole Java EE API ). See also: What exactly is Java EE? How do servlets work? Instantiation, sessions, shared variables and multithreading Tomcat is an application container that is also a web server. An application container can run web-applications (have

It seems that some servlet containers reuse HttpServletRequest (or more generally, ServletRequest ) instances between requests. Question: Can someone point to the servlet spec where this behavior (or the validity rules for references to such instances) is defined ? It is not defined in the Servlet API. It is an implementation detail. In 3.11 for request objects (and 5.6 for response objects) Each request object is valid only within the scope of a servlet’s service method, or within the scope of a filter’s doFilter method, unless the asynchronous processing is enabled for the component and the

Google search results suggested that it's possible via PHP/Java Bridge . This bridge requires Java Application Server. My host (bluehost) does not allow to run any Java Application Server. What are the alternatives in this case to make iText work? Switching a host is not viable option for me. Thanks. There's always iTextSharp , a C# translation of iText. Will your host let you run C#? It looks like you can call C# from PHP, as detailed here . I know this is an old post, but for those still looking for an answer, may I suggest having Java do your work for you as a REST service using Jersey (JAX

I'm having trouble undrstanding the difference about both platforms? Both seem to offer an environment for deploying and managing applications. First I thought app servers use OSGi under the hood, I don't think so now but I see large AS (jboss, glassfish, websphere, etc) use OSGi. What's the big picture? Thank you There is (to some extend) an overload of the term "application". OSGi is a runtime environment (and development model) for modular Java applications. The term "application" in this case can be really, really low level. For example, an application server can be considered such an

If I were to deploy an application on Tomcat vs. Websphere, what are things that I need to consider? Do I have to develop my Java code differently if developing in one app server vs another? Edit: I will be funneling people from a website into a web app that does credit card processing and e-signatures (cc processing and e-sigs are through separate services). That is its sole job You cannot use EJBs on Tomcat (unless you add OpenEJB). If your WebSphere deployment uses EJBs, you'll have to remove them to deploy on Tomcat. If you use any Java EE features beyond servlet/JSP engine and JNDI naming

I need to deploy a major deployment on my system (more that 15 ear file ) , my system is high available system , So how can I do this deployment with zero downtime ? my application server is IBM-WAS After updating the applications, you can utilize the " Rollout Update " feature. Rather than saving and synchronizing the nodes after updating, you can use this feature which automatically performs the following tasks to enable the changes to propagate to all deployment targets while maintaining high availability (assuming you have a horizontal cluster, such that cluster members exist on multiple
