JSTL中是否有if-else标签？

如何将Long值转换为IntegerJava中的值？

我正在从FindBugs获得以下bug,

发现依赖于MyClass.print(String)中的默认编码:String.getBytes()

方法

protected void print (String str) {
{
private OutputStream outStream = null;
.....
outStream.write(str.getBytes());
.......
}

请告诉我这是什么错误？我们如何解决这个问题？

提前致谢

我在RAD中收到以下错误:

java.net.URISyntaxException: Illegal character in path at index 16: file:/E:/Program Files/IBM/SDP/runtimes/base......

你能否告诉我这是什么错误以及如何解决？

Hibernate中Set和Bag集合之间的主要区别是什么？在什么情况下,我们应该用Set和Bag？

我有一个带有标识列的表.我需要从零重置该标识列.我该怎么办呢.

我安装了ant(apache-ant-1.7.0).但是当我在dos命令提示符下运行ant命令时,它说

‘ant’ is not recognized as an internal or external command, operable program or batch file.

哪里出错了

我需要使用Ant脚本复制除该文件夹中的目录之外的文件夹中的所有文件.

我使用下面的脚本来做到这一点.

<copy todir="targetsir">
  <fileset dir="srcdir">
     <include name="**/*.*"/>
  </fileset>
</copy>

但它会复制该文件夹中的所有文件和目录.

如何限制/过滤该文件夹中的目录？

谢谢,

我的代码出现以下Findbugs错误,

Invocation of toString on <<Package Path>>

 The code invokes toString on an array, which will generate a fairly useless
 result such as [C@16f0472. Consider using Arrays.toString to convert the
 array into a readable String that gives the contents of the array.
 See Programming Puzzlers, chapter 3, puzzle 12. 

码:

logger.info("Adding information"+ Employee.getName()+ " "+
            employeeForm.getQuestionAndAnswers());

请让我知道错误是什么.

我正在使用struts1.1.当我重定向到一个jsp文件时,我得到以下异常.我无法弄清楚错误在哪里.
