Issue while mapping REST

deepak · October 20, 2020, 9:36am

Hey Friends,

I have created a application (on windows) where I have rest mapping as below:
Virtual: /api
Physical: C:\lucee\tomcat\webapps\ROOT\sesAPIs

When I try to replicate similar in my prod environment which in on linux where mapping is done as below:
Virtual: /api
Physical: …\ROOT\sesAPIs

On saving the configuration i am getting the error page with below error:

Lucee 5.3.6.61 Error (java.lang.NullPointerException)

I believe this is something to do with the physical address I have provided.

Thanks.

the nice thing about open source and stack traces, is you can look directly at the source of the problem

github.com

lucee/Lucee/blob/5.3.6/core/src/main/java/lucee/runtime/functions/system/ExpandPath.java#L137


      
          				arr[index++] = m;
          			}
          		}
          		return arr;
          	}
          
          
	private static String toReturnValue(String realPath, Resource res) {
          		String path;
          		char pathChar = '/';
          		try {
          			path = res.getCanonicalPath();
          			pathChar = ResourceUtil.FILE_SEPERATOR;
          		}
          		catch (IOException e) {
          			path = res.getAbsolutePath();
          		}
          		boolean pathEndsWithSep = StringUtil.endsWith(path, pathChar);
          		boolean realEndsWithSep = StringUtil.endsWith(realPath, '/');
          
          
		if (realEndsWithSep) {
          			if (!pathEndsWithSep) path = path + pathChar;

I think you’re problem is that physical root on Linux should be using / not \ ??

Thanks Zac!!

I believe solution you suggested is working.

I was initially mapping the rest in the web interface.

/lucee/admin/web.cfm?action=resources.rest.

here i am getting the error which i posted.

I tried solution suggested by you in the server interface

/lucee/admin/server.cfm?action=resources.rest

and the it worked fine.

Now i want help to know how remove that error in the web interface? because this url /lucee/admin/web.cfm?action=resources.rest. always results in the error page
