Re: Issue with Range

[TKM]

3980273410 is the size of the file that i'm trying to transfer.  actually its
the index of the last byte of the file.  all of my variables are declared as
long -- the catalina stack trace shows:

at
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Integer.parseInt(Integer.java:461)
at java.lang.Integer.parseInt(Integer.java:499)
at 
org.restlet.engine.http.header.RangeReader.update(RangeReader.java:65)

so i guess i'll have to do more to manage a restarted transfer.  

thx.

Issue with Range

[TKM]

I'm using Directory to share files, but i would also like to allow aborted
transfers to restart.  Both server and client are Restlet implementations
that rely on streams for the transfer.   I added Range to the ClientResource
and started to get the message:  Internal Connector Error (1002) - For input
string: 3980273410.  When i look at catalina.log, i see
java.lang.NumberFormatException: For input string: 3980273410.   So, i'm
guessing that i can't use -1 as the Range size?  so the following is goofy?

ClientResource resource = new ClientResource(restRequest);
resource.getRanges().add(new Range(range, Range.SIZE_MAX));

The snapshot with the revised file upload works nicely on my system.  thx for
the fix.

Re: Upload to Directory 2.0m6

[TKM]

Thought I'd contribute this variation on the example from M.Abdel-Aziz
(thanks so much for the inspiration).   It was written using 2.0m6.  There
are 3 code fragments:  1. the routing, 2. a file upload ServerResource, 3.
code that inserts the uploaded file and its name (as specified in the URI)
into a blob in a mysql database table.  There are a couple more notes at the
end.

// 1.  file upload routing in a Restlet Application

Router router = new Router(getContext()); 
router.setDefaultMatchingMode(Template.MODE_STARTS_WITH);
router.setRoutingMode(Router.MODE_BEST_MATCH); 

Router uploadRouter = new Router(getContext()); 

uploadRouter.attach(, FileUploadResource.class);
uploadRouter.attach(/name/{name}, FileUploadResource.class);  

final ChallengeAuthenticator uploadGuard = new
ChallengeAuthenticator(this.getContext(), ChallengeScheme.HTTP_BASIC, 
Restful Access -- Please supply your 
credentials);
uploadGuard.setVerifier(myVerifier); 
uploadGuard.setNext(uploadRouter);
router.attach(/fileuploads,uploadGuard);

/**

json stack overflow

[TKM]

i'm seeing a stack overflow error in catalina.log when i try to return a json
rep of a resource with 20 fields.  same code worked perfectly a month ago,
so i'm wondering if anyone else has seen the problem.  I'm attaching the
code and stack trace.  I'm running 2.0m5 on osx 10.6.1.

duh.  thank you.

 That looks to me that you URL to buildings is http://localhost/

Re: A simple URI problem -- followup

[TKM]

It is likely that my problem has to do with how I am defining my application
in Tomcat.  I'm not using a war file and in my server.xml file, i specify
the default context

Context path= docBase=myApplication debug=5

So, there is probably something that Tomcat is doing with a typical uri
reference like http://127.0.0.1:9006/myResource/buildings/indiana   

btw, if i specify the typical mapping (url-pattern/*/url-pattern), then
i get a nice xml rep of the indiana data -- but the rest of my application
is broken since other servlets cannot be referenced.
