S2: basic question on rest plugin
Hello All, I'm experimenting with the rest plugin (2.1.8) using the example struts2-rest-showcase as a starting point. I wanted to implement a simple search such that a URL like http://localhost:8080/struts2-rest-showcase-2.1.8/orders?amount=66 returned a list of order with the amount of 66. I approached this by adding an amount property to the controller and corresponding setter method and then modifying the controller's index method to use that value to constrain the results. Problem is that the amount never gets set either on the controller or on the model. Can someone please help me understand what's going on or suggest a better way to approach this problem? Thanks! --john - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: RE: S2: basic question on rest plugin
Thanks for your reply Martin, I think I now have it working using the attribute
on the model.

S2: multiple file upload
Hello All, I'm having trouble getting the FileUpload interceptor (v2.0.14) to work w/ multiple files. My form looks like this: s:file name=shapefile[0] label=shapefile / s:file name=shapefile[1] label=shapefile / s:file name=shapefile[2] label=shapefile / s:submit name=upload/ and then my Action contains: File[] shapefile; String[] shapefileContentType; String[] shapefileFileName; w/ corresponding setters: public void setShapefile(File[] files) public void setShapefileContentType(String[] contentTypes) public void setShapefileName(String[] names) problem is that Parameters interceptor is trying to set shapefile[1]FileName. I first tried elements w/o the index like: s:file name=shapefile label=shapefile / s:file name=shapefile label=shapefile / s:file name=shapefile label=shapefile / but then I got a single shapefile parameter w/o separators.

S2: @SkipValidation annotation
Hello All,
I'm having trouble getting the SkipValidation annotation to work. I
have a single action w/ multiple methods. Some of the methods don't
require any input and I'd like to skip validation, e.g.
@SkipValidation
public String list() {
return(list);
}
However the annotation does not seem to prevent the validate method from
running and short circuiting the process. I'm using Struts 2.0.14 and
have included an excerpt from my struts.xml below. Can someone please
help me here?
Thanks!

Re: S2: chart result type not recognized
Hi Ian, thanks for your reply. For testing purposes, I'm simply calling it via URL: http://localhost:8080/viewer-commons-2.0/chart/serverIronLoadChart.action Strangely, I was able to get the chart example from the docs to run in new context, I just can't seem to be able to integrate it into a more complex existing application. I'm assuming that the result type is not being recognized, but don't see any errors in the logs and don't know how to pursue debugging the problem.

Re: RE: S2: chart result type not recognized
Thanks for your offer to help Martin!
Listed below is the struts.xml, web.xml, and source for the Action class
(taken straight from the docs).
I'm testing it by simply typing the URL into the browser:
http://localhost:8000/viewer-commons-2.0/chart/ViewModeration.action
I notice that if I embed the same URL into the src attribute of an img
element in an html page, the chart displays. Makes me think perhaps the
mime type is not being set. Is this possible? In that case would I
potentially get different behavior from Apache/Tomcat on different
platforms (Mac vs Linux)?

Re: error in strutsel-exercise-taglib
Thanks for your reply, David. I'm not sure that I understand though. I
am using tomcat 5.0.x and JSP2.0. However, when I change the taglib
directive to:
%@ taglib prefix=html uri=http://jakarta.apache.org/struts/tags-html%
and try something like:
html:img src=${images[iconClosed]} height=16 width=16/
(where images is a HashMap in request scope), I get an error. Indeed,
the documentation for the html:img taglib specifies a RTExpr.
Can you clarify for me?
Thanks!

In fact, it won't work. I don't know what this particular exception is,
but you can avoid this situation entirely by just not doing it.
