(java.lang.NoClassDefFoundError javax.crypto.Cipher.getInstance) when trying to execute JSP

I have (java.lang.NoClassDefFoundError javax.crypto.Cipher.getInstance) when trying to execute JSP it a couple of times and spent quite a lot time initially to figure out what is wrong, which class is missing etc. The first mistake I did was mingling java.

Java Classpath they are completely different to each other. Compile time and that’s why the program successfully compiled but not available during runtime for any reason. Classpath, so we need to add that into Classpath or we need to check why it’s not available in Classpath if we are expecting it to be. The class is not available in Java Classpath. Any start-up script is overriding Classpath environment variable. JAR file or JAR was not added into classpath or sometimes jar’s name has been changed by someone like in my case one of my colleagues has changed tibco.

In order to solve this keep your dll along with JAR. If you are running your Java program in a multi-user operating system like Linux then you should be using application user id for all your application resources like JAR files, libraries, and configuration. As most of Java frameworks like Spring, Struts they all use XML configuration for specifying beans. EJB class doesn’t found that because it was loaded by WAR classloader which is a child of it. One of the examples of this scenario is just delete the User class from our static initializer failure example after compilation and they try to run the program. User class from the testing package. Watch out for this carefully as here root cause is absent of User.

Java In-Depth: Become a Complete Java Engineer! I checked the classpath and seems class is there. Is it the same as the discussion above? If yes, how do I fix it? I’m sure I placed the necessary files in the correct locations, according to a manual specifically for PTA. Many times it happened with me that my classes were compiled with JRE 1.

Displaytag has dependency on some third party jars like apache commons lang, poi , tyring adding all those library and you will be fine. I have written a filter to authorize my application which takes ldap details from context. I have used spring to create objects to the bean in the context. I’m trying to get a class to run in an Eclipse project. It doesn’t seem right that I can’t generate the byte code for the class ’till I have the byte code for that class. I use eclipse, and when i do system. The situation is my uni is marking our java assignment using a system called Plate.

You must have the first two lines of code for PLATE to run. I use BlueJ as the IDE. My code runs if I run the main method, but is not running after I exported to jar file. When exporting, I chose, include source, Main clas: Trader. Here is my jar, if you can take a look at it, that will be great. Pointed me to my mistake, which i just spent 2h or so. I just don’t know what are those Eclipse options.

I check my classpath and nothig wrong ! The issue in my jar file was that classpath was not being picked up when declared in shell file. I added required class path to ant build file that inturn added it to manifest. Hi everybody, I have this problem ONLY with Eclipse: if I try to compile by terminal this is all right. The application runs as appuser and imports failedlcass from the class-loader. Changing the owner back to appuser resolved the issue.

The app’s architecture is that I have a free and a pro version that both are using the same library project. Android manifest mentiones the activity explicitly. Am i supposed to add the library project’s jar explicitly to the classpath? SEVERE: Exception sending context initialized event to listener instance of class org. I have posted 1 issue in Jan-05.

I think I have installed the Mac Java update, but still no luck. I think there is a more fundamental problem.

I have just tried to compile the . I have tried also setting the classpath and the sourcepath. If you have any further insight that would be gratefully appreciated. GUI is it “grui” or “gui” ? When you have this kind of problem you have to be sure that all the jars are added in the main project’s build path. That last jar file was the problem.

It wasn’t in the build path of the main project. The problem was solved when I added it in the main project’s build path. The “cause” was running with ‘-jar’ parameter. Do you see anything obvious here? I do have Java_Home in the classpath. It worked fine when I removed the .

I simply saved the class, then deleted it from eclipse and then rebuilt it. It won’t be possible for us to pin-point exactly what has caused this without actually seeing the details.
