我正在尝试编译AdminOps.java文件,它是软件包adminOps的一部分
这是文件结构:
C:\ Users \ Hp \ git \ fls-web-Lucy \ src \ adminOps \ AdminOps.java
根据Ant的输出,我认为Ant无法找到javax.servlet。
我尝试手动导入javax.servlet-api-3.1.0.jar文件,但仍然出现错误。我正在使用build.xml文件,以便可以创建WAR文件并使用XAMPP将其部署在localhost上。
谁能帮我找出问题所在?

由于Tomcat是XAMPP的一部分,因此我没有单独安装它。这会产生问题吗?
最佳答案
在您的Ant脚本中,代码段...
<javac ... classpathref="classpath" ... />
...配置
<javac>
在classpath
定义的路径中搜索库。在您的脚本中,classpath
被定义为...<path id="classpath">
<fileset dir="${jar.dir}" includes="**/*.jar"/>
</path>
所以:
javax.servlet-api-3.1.0.jar需要在
${jar.dir}
下存在。或
<path id="classpath">
需要另一个<fileset>
指向javax.servlet-api-3.1.0.jar。
