这是从示例javafx2.1软件包运行示例DataApp应用程序时面临的挑战:我正在运行Netbeans 7.1.2,javafx 2.1。,glassfish 3.1.2,Java EE6,并且我有6gig ram。
当我右键单击DataAppServer项目或我对DataAppClient项目执行相同操作并点击Run时,我收到以下错误消息:
C:\Users\Staples\Desktop\ITOWER STUDIO\javafx-samples-2.1.1\src\DataApp\DataAppServer\nbproject\build-impl.xml:533: The following error occurred while executing this line:
C:\Users\Staples\Desktop\ITOWER STUDIO\javafx-samples-2.1.1\src\DataApp\DataAppClient\build.xml:48: Problem: failed to create task or type javafx:com.sun.javafx.tools.ant:application
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet
BUILD FAILED (total time: 8 seconds)**
我尝试添加一个taskdef标签,如同在类似问题中所解释的那样,但它也会出现同样的错误。当我打开项目并连接到MySQL数据库时没有错误。这是我添加的taskdef标签:
<taskdef resource="com/sun/javafx/tools/ant/antlib.xml"
uri="javafx:com.sun.javafx.tools.ant"
classpath="C:\Program Files(x86)\Oracle\JavaFX 2.1 SDK\lib\ant-javafx.jar"/>
第48行显示了这个字符串:
preloaderClass="dataapppreloader.DataAppPreloader"/>
和第533行显示:
<ant antfile="${project.DataAppClient}/build.xml" inheritall="false"target="jar">
我真的被困在这里了。需要帮忙。感谢。
答案 0 :(得分:0)
..告诉你添加
<taskdef resource="com/sun/javafx/tools/ant/antlib.xml"
uri="javafx:com.sun.javafx.tools.ant"
classpath="C:\Program Files\Oracle\JavaFX 2.1 SDK\lib\ant-javafx.jar" />
下的
行 <target name="-post-jar" depends="-init-javafx, -jfx-copylibs">
在DataAppclient文件夹的build.xml文件中
