java.lang.ClassNotFoundException : org. owasp.encoder.Encode

Question

我正在尝试在我的 java 类中使用 OWASP 编码器库来对输入进行编码，但我没有任何运气。它一直给我这个

java.lang.ClassNotFoundException: org.owasp.encoder.Encode and java.lang.NoClassDefFoundError: org/owasp/encoder/Encode

我将 JAR 包含在 -classpath 中关于编译。不知道还能尝试什么

/usr/java/jdk1.6.0_20/bin/javac -classpath /path:/path/encoder-1.1.1.jar xxxx.java

这是堆栈跟踪:

它还需要运行时类路径中存在该 jar

像这样运行

/usr/java/jdk1.6.0_20/bin/java -classpath /path:/path/encoder-1.1.1.jar xxxx
