The Jar file that I am using already have its own existing class files and I would like to update one of the the .class file with a few lines of codes. But when I copied the codes from the class file and put it into a java file together with my added lines of codes, and then try compiling it

问题 The picture is self explanatory. When I validate the document using identical process in CMD, the document is declared valid. It is valid when checked manually. The jar file generates this message: Invalid schema_reference.4: Failed to read schema document 'E:/XML and Java/Pro XML Development with Java/schema.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. The question is: WHY? The process of validating

问题 I've done several projects and packaged them into jar files, but I've noticed that my jar files run much more slowly than in my IDE. I use Eclipse to compile and run my programs. In Eclipse, I have everything working. When I package my project as a runnable Jar and execute it by double-clicking, everything still works. But when I have animation, the program runs extremely slowly. Instead of 30 frames per second in Eclipse, I now get about 2 frames per second. The animation is very laggy.

问题 I'm trying to use Maven to create an executable jar file that includes the dependencies in a separate directory. I've seen a lot of questions on SO about creating an "uberjar"--I don't want that. What I want is to have the depenedencies copied into a "lib" directory like so (and the jar MANIFEST.MF file with a ClassPath entry that points to them): /myApp myApp.SNAPSHOT-1.0.jar /lib hibernate.jar log4j.jar ... As an added bonus it would be nice if I could copy /src/main/resources/* into /myApp
