阅读更多关于 How to self-sign an applet with NetBeans?

问题 In the previous months I developed a sandbox applet for an academic project. Due to the Java 1.7.51 security restrictions to applets, I have been trying to self-sign my applet with the hope that it can comply or overcome JRE's requisites for applets. I'm using NetBeans and I have taken as a point of departure some links that show how to self-sign a jar file. Unfortunately, I haven't been able to get it working. I have tried to add the following instructions on the build.xml file: <target name

Sign SOAP request on client-side with Spring

阅读更多关于 Sign SOAP request on client-side with Spring

问题 I have read the Spring doc regarding Securing your Web services with Spring-WS but it looks for me as if the article is just regarding server side and not client side.

Am I right and chapter 7 of Spring Web Services documentation just apply to server side? Second. It is possible, to add security, like signed headers, to SOAP requests on client

Python: Pass inequality as string in dict for evaluation

阅读更多关于 Python: Pass inequality as string in dict for evaluation

问题 I need to pass inequalities to a function for evaluation within the function. Is there a way to evaluation the inequality if passed as a string? Or must I pass a representation of the inequality and use if/else statements to generate the sign? 回答1: Your question is a little vague, but it sounds like you want to evaluate a string containing an expression (such as x > 5 ). Rather than doing that, which is unnecessarily complex, and potentially a security hazard, just define a function, either

问题 I have to do a sign extension for a 16-bit integer and for some reason, it seems not to be working properly. Could anyone please tell me where the bug is in the code?
