gwt - How to formulate a JSONP request -

-

I am in the process of learning about GWT, I am currently experiencing problems in making an RPC call on a specific server using JSONP.

.

The server wants to communicate with the Jason-RPC service for which {'content-type': 'application / JS'} , and for example: { "Params": ["hollosver"], "method": "server.greeting", "id": 10} .

I wonder if it is possible to request JSONP on this server, because I think that JSONP is the only only solution, similar to Origin Policy restrictions of GWT. Edit : As mentioned, I think I have to be on JSON because the server does not provide JSONP service suggesting that the solution of SOP is correct It has also been suggested.

I wonder if it is possible to request a JSONP on this server

If the server does not support it, then no. To support JSONP server response is required: ": 10})

Where some callback is the name of a function that can be specified by the client If you do not have control over the server and do not support JSONP then you have to write a server-side script on your domain which will act as a bridge. Then you will send an AJAX request to this script which is distributed on the remote domain Do Gay.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
