[opencms-dev] Compiling Java Sub-Classes

[Paul-Inge Flakstad]

Hi Frank

You could just create a Java class library, and export it as a .jar file using your IDE (Eclipse, from what I gather). If you don't know how to do this, you'll find tutorials on the web, just google a bit.

If you then upload the .jar file to your /system/modules/your.module.name/lib/ folder, you will have your classes available and ready to use. E.g. if you want to use them in a .jsp file, all you have to do is import them using the page import directive: <%@ page import="your.package.name.YourJavaClassName"%>.

It's strictly speaking not even neccessary to create your own module, you can just upload your .jar files to any /system/modules/****/lib folder - though I recommend you add them to your own modules.

The "drawback" of using .jars is that you'll have to restart Tomcat (and I assume you're using Tomcat) in order for your system to be aware that the .jar has been added or modified. (If you use .class files, I suppose you won't have to restart after adding or modifying your files - but I can't tell you anything about this approach, as I've only been using .jar files.)

Hope this helps.

Cheers,
Paul

Subject: [opencms-dev] Compiling Java Sub-Classes


Hello,

presently I am wasting a lot of time on trying to compile Java-Classes for OpenCms templates (according to the packt-publishing book "OpenCms 7 Development".
Unfortunately they only explain, how a Subclass is developed but there is not a word, how I can compile itand in which directory I have to copy it in the VFS. I adapted the suppied java-source-file of the Blog example since I changed the directory in which the index.html resides. But I don't know how to compile the java class inside eclipse and where to copy it. There are no ".class"-files in the "/system/com.deepthoughts.templates"-directory.
So please can anybody help me to solve this problem?

Thank you in advance
