System.getProperty can't read jnlp - resources since java 7 - Could this be because of an unsigned JNLP-File -


I try to eliminate a Java Web Starter application, since the witch is broken by java 7. All jar files are signed

I try to get information about resource-tags from my jnlp-file

I use System.getProperty but this blank.

I searched for a while but I could not find any answer to the following questions:

  1. Do I have to sign the JNLP-file so that the resource tag?
  2. If I do, how can I do this? I have read that I have put it in the jar just like the initial class, but I do not get this good instruction.
  3. I have read, that JNLP should be named APPLICATION. Be nice in JNLP and JSLL-INF folders. Is it necessary? What's in this folder? Can he be anywhere?
  4. I've read what's new in Java version 7, from Java. I did not get a change in the system .getProperty and the security manager was used in this function. Am I right, that this change has not happened?

Here I find the important part of the code:

OK, it's a line that I try to get one of the resource tags: 

  string strApiPath = System.getProperty ("uppath"); Println (strApiPath);

  • need to sign with the certificate of the jars the (self-signed with the certificate)
  • manifest file needs to be updated - see

some output warning but allow "tags required tag is.

What type of error are you getting?

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
