我正在使用 Eclipse Neon 和 Tomcat 服务器 9.0 和 JDK 1.8 它运行良好,但不幸的是它给了我错误“Server Tomcat v9.0 Server at localhost failed to start”。我尝试更改端口,即连接端口和其他端口,但它没有解决我的问题,并且当我启动服务器或运行我当前正在处理的网络应用程序时,会显示此错误。除了更改端口之外的其他解决方案,因为我尝试过但它没有解决我的问题???

输入测试用例如下:
test.describe("Testing function to_camel_case")
test.it("Basic tests")
test.assert_equals(to_camel_case(''), '', "An empty string was provided but not returned")
test.assert_equals(to_camel_case("the_stealth_warrior"), "theStealthWarrior", "to_camel_case('the_stealth_warrior') did not return correct value")
test.assert_equals(to_camel_case("The-Stealth-Warrior"), "TheStealthWarrior", "to_camel_case('The-Stealth-Warrior') did not return correct value")
test.assert_equals(to_camel_case("A-B-C"), "ABC", "to_camel_case('A-B-C') did not return correct value")

这是我到目前为止所尝试过的:
def to_camel_case(text):
str=text
str=str.replace(' ','')
for i in str:
if ( str[i] == '-'):
str[i]=str.replace('-','')
str[i+1].toUpperCase()
elif ( str[i] == '_'):
str[i]=str.replace('-','')
str[i+1].toUpperCase()
