java - How can I read data from USB? -

-

I got a question: I have found libusb library for Java, but I really do not understand how to read some data Go. ReadBulk () or readInrrupt is a method, but they have an integer form of return type. I do not know how the data is stored, because the method only gives the actual number of bytes, the method that was read. The command class supports a method called getInputStream (), in this method there is a return type of the inststream and so I can do something with that data.

I am trying to get a basic CXF RS JX-RS example for working. Unfortunately, the GET on a resource which I want to return HTML does not apply the resource at all. Here is an extraction from spring bean: & Lt; Bean id = "HelloResource" class = "com.example.HelloResource" /> & Lt; Camelcontext xmlns = "http://camel.apache.org/schema/spring" & gt; & Lt; Route & gt; & Lt; From Yuri = "cxfrs: bean: rsssver" /> & Lt; From Yuri = "Log: Later?

ajax - Decimal('12000') is not JSON serializable -

-
I have a dijongo example running on Apache 2. One of my webpages is doing an AJAX callback to the project. Most of the time, it works great, but for some reasons I can not determine this, it stops working with Django from the following error: Decimal ('12000') is not a JSON serial Once I get this error once, it stops working for ever. I know that the only solution is to start Apache again. Python / Django is not changing, nor does the data requested by Ajax calls. I never got this problem when I ran my code on Django web server. @login_required def KPIInitTable (requested): kpi_values ​​= [ob. KPI.Obages '' As_json () for OB in March '' 'table_data': kPI_group, 'callheader': ['kpi', 'citecatcher', 'type', 'jan', 'february' 'April', 'May', 'Jun', 'Jul', 'Aug', 'September', 'Oct', 'Nov', 'Dec' '],' Roha Headers...
