If there is already an entry in the store with alias s1as, all you have to do is perform step 4 as described in "When the Enterprise Profile is Used" to delete the original entry:                certutil -D -n s1as -d $AS_NSS_DB  Then perform step 5 to import the new s1as.pfx file into the NSS store:                   pk12util -i s1as.pfx -d $AS_NSS_DB  If there is no entry in the store with alias s1as, simply perform step 5. The application server profile is the developer profile and the server key pair is already in a PKCS#12 file. In this case, all you need to do is perform step 5 as described in When the Enterprise Profile is Used to delete the original s1as entry. Then use the pkcs12import utility to import the PCKS#12 file into the GlassFish keystore:                pkcs12import.sh -file s1as.pfx -alias s1as       -keystore keystore.jks -storepass changeit       -pass <exp_password> where <exp_password> is the password that was used when the PKCS#12 file was exported, for example, changeit. You can find the pkcs12import utility in the pkcs12import package, which you can download from the XWSS downloads page in Project Metro Thu, 30 Apr 2009 11:45:30 GMT http://www.javafaq.nu/index.php?name=News&file=article&sid=1192 When the Cluster Profile is Used You perform the same steps to enable GlassFish v2 as an SSL server when the application server is configured with the cluster profile as you do for a developer profile. However, in this case you need to ensure that the same server key in replicated in all the application server instances in the cluster. When the Enterprise Profile is Used The Security Store parameter value for the enterprise profile is NSS, which stands for Network Security Services. In an NSS security infrastructure there is no JKS keystore and so there is no default GlassFish keystore.

Let's first examine the process if the developer profile is used. Then let's examine the process when the enterprise profile is used. When the Developer Profile is Used Thu, 30 Apr 2009 11:39:58 GMT http://www.javafaq.nu/index.php?name=News&file=article&sid=1190 SSL with GlassFish v2 By Kumar Jayanti Most enterprise applications need to run in a secure environment. Transport Layer Security (TLS)/Secure Sockets Layer (SSL) is a point-to-point secure transport mechanism that can be used for authenticating messages exchanged between a client and a server, and for ensuring message integrity and confidentiality. TLS/SSL (or in this tip, simply "SSL") meets the security requirements of most enterprise application environments, and is widely adopted. However to participate in SSL-secured message exchanges, the server needs to be enabled as an SSL server. This tip will show you how to enable the GlassFish v2 application server as an SSL server.

For example, the block for the main method is nested within the block for the App class in the sample program.

It is new site and have not so much articles but can be helpfull for those who has no knowledge about robotics. Site publishes articles on regular base and soon will become bigger. Here you can find descriptions, code examples and references to how use Java in small processors and microcontrollers.

As stated previously, Java requires that a method either catch or specify all checked exceptions that can be thrown within the scope of the method. This requirement has several components that need further description: "catch", "specify," "checked exceptions," and "exceptions that can be thrown within the scope of the method." Thu, 28 Feb 2008 21:16:41 GMT http://www.javafaq.nu/index.php?name=News&file=article&sid=1184 Advantage 3: grouping error types and error differentiation Part I was published here. Often exceptions fall into categories or groups. For example, you could imagine a group of exceptions, each of which represents a specific type of error that can occur when manipulating an array: the index is out of range for the size of the array, the element being inserted into the array is of the wrong type, or the element being searched for is not in the array. Furthermore, you can imagine that some methods would like to handle all exceptions that fall within a category (all array exceptions), and other methods would like to handle specific exceptions (just the invalid index exceptions, please).

What's an exception and why do I care? First encounter with Java exceptions. Java's catch or specify requirement. Dealing with exceptions.

It is true! Exactly 10 minutes you need to download it, run with your program and find why your program spends much memory and time in just that Java class! Find why just one-two classes try to sabotage the whole your Java project JProfiler enables Java developers to tune up the performance of their Java programs. It combines in a single tool the capabilities for detailed examination of VM load and applications’ work, for memory usage and CPU loading, etc. JProfiler is an ideal choice for profiling of embedded devices and target boards, due to the highly optimized architecture and low memory consumption of the agent profiling component. JProfiler allows for both local and remote profiling. It can be used as a stand-alone tool or within the Eclipse environment. Sat, 16 Feb 2008 22:27:54 GMT
