我目前正在开展一个学校项目，我们必须通过python脚本在cgi网站上运行一个jar文件。
我的jar输出看起来像这样：
String str = "<body>"+str+"</body>";
BufferedWriter writer = new BufferedWriter(new FileWriter(s+".html"));
writer.write(str);
writer.close();
我的python脚本是这样的：
#!/usr/bin/env python3
import cgi, cgitb
import os
import subprocess
cgitb.enable()
HTML="""
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Validation</title>
</head>"""
HTML2="""
</html>
"""
out = subprocess.check_output(["java -jar test.jar])
print(out)
如果我运行它总是给我一个语法错误任何帮助非常感谢。

进程以退出代码1结束
不应该out = subprocess.check_output(["java -jar test.jar])：
out = subprocess.check_output(["java -jar test.jar"])？
（缺少关闭"）
如果这不是问题，我们需要查看完整的堆栈跟踪。
