“I have worked with many different servlet engines (some are app servers too) like Jrun, jServ, Tomcat, Orion, WebLogic etc and in the neighbourhood of servlet/jsp engines your product has sold me as being the best of the breed. I’m also anxiously awaiting the newest version of your Resin Hardcore…

Keep up the good work.”

“We’re using Resin with WebLogic because the JSP engine is faster, and the xsl transforms would be far too heavy to load onto a machine that is already bogged down with heavy EJB traffic.

It is also far easier (and cheaper) to cluster Resin to handle all of the servlets, JSPs and XSL transforms onto multiple heavy-weight servers than it is to keep spending money on licensing fees for clustered WebLogic licenses.”

“It’s things like this, the excellent technical support, and the general feeling of ‘good people’ that keeps us as customers. We have had people in upper management asking why we don’t use JBoss… there’s just no comparison. You’ve gone above and beyond, so thank you.”

“We have used Resin as our JSP application server for years. We are impressed with the speed and stability as well as the keep-alive feature. Our resin server runs for months at a time without maintenance.”

“The Caucho Resin application server is at the core of our product’s infrastructure, and due to its stability and reliability we’ve been able to achieve phenomenal uptime and performance for our Enterprise SaaS project portfolio management (PPM) software. While most companies with SaaS products focus primarily on small-to-midsize businesses, PowerSteering is used by global enterprises and government organizations with large, worldwide deployments. We could not serve the need of such demanding, geographically diverse users without the cost effective, feature rich, and scalable solution that Caucho provides.”

“With Resin we have vastly reduced memory requirements by setting the startup-mode for each host and using shared libraries. OpenEdit hosting also uses the quick reload ability and the great performance of Resin to keep uptime in the high 99.99 percentile. Resin and OpenEdit are a perfect combination to build fast, full featured and reliable web sites for clients.”

“I’ve worked with Caucho/Resin for 12 years now, introduced it at 2 companies, one of which the largest newspaper in the Netherlands and it has never disappointed me.”

“Resin is by far the best JSP engine out. I’ve been using it with Apache on Solaris and also with IIS 5.0 on Windows2000. It it easy to configure and works very nicely.”

“I’ve been using Tomcat since it was first donated, submitted patches, and all that. I’m actually a lead contributor to the JAMES software that was just ported over to the Jakarta site. Anyway, nothing against those guys… I think the Tomcat group is doing an ok job, but I wholeheartedly recommend Resin over Tomcat. We’ve been using Tomcat across almost all of our projects, and we’ve been burnt a lot. Basically it’s a reference implementation (not a production grade or commercial feature-filled server), which is fine because that’s their objective… arbitrate over the specs and do an ok job implemented it. Anyway, we’re in the middle of porting everything we can over to Resin.

I’m sure I’ll get flamed for this, but I’m getting pretty sick of restarting this Tomcat server every few days that is handling about a million hits a month… it’s all db driven and has some intense reports, but still, if I wanted this kind of total cost of ownership, I would have used Microsoft. :)”

“Once we made the move to Resin the availability of our services significantly increased…using Resin helps us scale and grow our services much more easily.”

“We have been using Resin for over eight years in a notoriously demanding environment. Resin has consistently provided us with the speed, resilience and flexibility we need to meet these goals, not to mention the first-class support provided by Caucho.”

“I have to say that your dedication to helping Resin developers and continued improvement of an already-great tool are incredible and set an extremely high standard for the rest of the industry.”

Given that everything you can do with weblogic you can do with Resin (or Resin + third party projects such as jBoss) for far cheaper, faster and with much less overhead, I’m convinced there’s only two reasons anyone would use weblogic:”

• Massive cost is self-justifying to the beanheads (”it must be the best!”)
• Two words: Management Console. If you’re in management, you need a console.

“Our servers handle tens of millions of requests per day. Our customers require up to the second market data. We need a robust application server that can handle that load without getting in the way. Resin gave us that before anyone else got close, and continues to lead the way with superior performance, frequent updates, and superb support.”

“I’ve been using Caucho’s Resin application server for over ten years, and it has been the foundation for our backend Java applications ever since.”

“Your engineers have helped us solve several onerous problems by providing timely review of sent logs and highly effective troubleshooting tips. We have some great software developers here but occasionally even they get stuck and need the deep technical understanding the Caucho staff provides. Resin has proven itself to be a stable yet versatile product and it’s really great to see such a talented staff behind it.”

“Honestly you are really better off sticking with Resin. Indeed my experience with Tomcat was extremely frustrating. I would say the best thing about is the documentation available on caucho’s web site. I found extremely well documented…

The real advantage of Resin for us is its support for caching; Our pages are built up with “template JSPs” that includes 1..n JSPs for each “sub-part” of the page, where these sub-parts are cached individually (most of them are obtaining their data through beans which in turn uses JDBC to talk to our databases). Resin then takes care of all the caching issues for us, and we can enjoy a unix-server serving 1.6-2.0 mill. pageviews pr/month with almost no load (< 0.50), and database access is only needed when the given JSP needs to be refreshed because its cache TTL has expired (when cached the pages are served with the speed of static pages - or even faster than static pages served from disk when the cached JSPs are fetched from memory (!))”.

“in that case use Resin! … with Resin you just copy the updated source files and refresh the page! it really is very fast and easy to use…

I started using Tomcat here at work to prototype a new web site we’re developing, but found the documentation to be very lacking. We then looked at Resin and found that along with great documentation it has excellent support… and the other people on this mailing list. I was on the Tomcat mailing list for a while and it seemed that 99% of the traffic was people asking things that should have been in the documentation if not at least in a FAQ.

I think Resin is much faster, easier to install/configure, and has much better support.”

“Hey guys, I just wanted to thank you for the great project! I’m using Resin1.1b4 for an intranet site and the response time is so fast that users think we’re using client-side scripting!

I have been using the Struts framework almost since it came into being. At first, Struts and Resin had some disagreements. Those were worked out, with both parties interested in cooperating with each other. That was many months ago. Today, the combination of Struts + Resin provides a very powerful environment in which to develop web applications.

In contrast to how quickly problems are fixed in Resin and in Struts, I have read so many messages about problems with WebLogic that I am amazed that people would even pay for it. That it commands a price of around $15K per processor is completely mind-boggling…”

“I am enjoying working with Servlets/JSP after ASP. They are actually very similar (I was quite surprised) and JDBC is very similar to ADO in a lot of ways. I am enjoying learning new things.

The great thing about RESIN for me is that I work in a total MS environment. Resin allows me to use java in that environment and that is great! Your product is excellent, and I will be doing everything I can to encourage my company to buy it.”
