Tutorial - Web Application Modules (WAMs) - 404

[Weissnix]

Hello everyone,

I'm new to LANSA programming and currently working on Web Application Modules (WAMs).

I'm watching this tutorial:

https://docs.lansa.com/14/en/...

I noticed that there is no CSS in the design view. The design is just HTML and there is nothing to choose from in the Class dropdown. see screenshot

And the second problem: When I execute and the browser calls this URL: http://localhost:8080/lansa/lansaweb?wa ... UT&lang=DE

I get HTTP Error 404 - Not Found.

When I get http://localhost:8080/ I get the "Welcome to the "LANSA" website, created by the LANSA install."

Do you have any tips for me?

Tip# 1: Don't use WAM's. Use VL-WEB.

Did you compile your WAM?

Hi Weissnix

I Agree with Art (if you are just starting to develop for Web) use Web pages instead of WAMs.

However, if you have to maintain existing WAMs, then going through the tutorials is a good idea.

On the bottom of the IDE you will see "LANSA:XHTML". Click on it and you will be presented with this dialog:

Run the first two tests. If the first one passes (you have a working web server) run the second (you can run a WAM webroutine).

If the first test fails, contact Support who will help you troubleshoot your installation. If it passes, run the second one and if the page loads but the page doesn't look right, press F12 (developer tools) on your browser and see what errors are shown.

Forgot to mention to first confirm Art's suggestion that you have compiled your WAM.

Cheers

I agree with the others that have posted here already. For new web development, don't proceed with WAMs as you are starting with a technology from 2005 and this isn't the technology that LANSA will be pushing on with in terms of future development and enhancements. The WAM technology is in a 'fixes only/no further enhancements' status. There's even a notice regarding wams posted on the support section of the web site https://www.lansa.com/support/tips/t0639.htm

I'd suggest to...
Install or upgrade to V14 SP2 and execute any of the sample apps from the home page in the VL IDE. Or create your own version of the apps based on the sample apps. Checkin and compile and execute against the IBM i.
Or if you are on an older version of LANSA and, for application maintenance reasons, cannot upgrade then just download the free trial from the LANSA web site and play around with with the web samples in that environment.

First of all thank you and apologize for the late reply, many other projects ...

Thanks for the hint, I'm really inexperienced in this area and just worked my way through the tutorials

Thank you for the link and the hint, I will follow the advice.
I have also already installed the latest version V14 SP2 with the latest EPC

Your WAM is not compiling due to the errors shown.

If you use fields defined in the LANSA repository, you don't need to define them in your RDMLX, just use them. When you define your own fields, don't start their names with "std" or" x", as these prefixes are reserved for fields and components shipped by LANSA.
