    11-27 03:32:04.471: E/AndroidRuntime(23137): Caused by: android.database.sqlite.SQLiteException: near "order": syntax error (code 1): , while compiling: create table order (_id integer primary key autoincrement, origin text not null, quantity integer not null); 

MyDatabase类:

public class MyDatabase extends SQLiteOpenHelper {

    public static final String TABLE_NAME = "order";
    public static final String TABLE_ID = "_id";
    public static final String TABLE_ORIGIN = "origin";
    public static final String TABLE_QUANTITY = "quantity";
    private static final String DATABASE_NAME = "Appple.db";
    private static final int DATABASE_VERSION = 1; …

我正在编写一个 PrimeFaces 应用程序。我的 XHTML 中有以下代码：

<p:selectOneMenu value="#{lottoCheckerBean.selectedPowerBallDrawingDate}">
    <f:selectItems value="#{lottoCheckerBean.powerBallDrawingDates}" />
</p:selectOneMenu>

我期待在LottoCheckerBean选择一个值时在我的下面执行以下代码：

public void setSelectedPowerBallDrawingDate(String selectedPowerBallDrawingDate) {
    //get drawing
    PowerBallDrawing currentDrawing = null;
    for (int d = 0; d < powerBallDrawings.size(); d++) {
        if (powerBallDrawings.get(d).getDrawingDate().equals(selectedPowerBallDrawingDate)) {
            currentDrawing = powerBallDrawings.get(d);
            break;
        }
    }
    if (currentDrawing == null) {
        try {
            //create new drawing;
            currentDrawing = new PowerBallDrawing(selectedPowerBallDrawingDate);
            powerBallDrawings.add(currentDrawing);
            Arrays.sort(powerBallDrawings.toArray());
        } catch (Exception ex) {
            //will not happen so ignore
        }
    }
    this.selectedPowerBallDrawingDate = selectedPowerBallDrawingDate;
}

但是，如果我在上述方法的开头设置了断点，则不会到达断点。

我错过了什么？

在 json-schema-validator 2.1.7 jar 中获取以下提到的异常：

java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/TreeNode
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:621)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:466)

我在用：

• json-schema-validator 2.1.7 jar
• json-schema-core 1.1.8 jar
• jackson-coreutils 1..0 jar
• jackson-databind-2.2.2 jar

代码片段如下：

            System.out.println(" inside json validation -- 0");
            JsonNode data = JsonLoader.fromString(responseString);
            System.out.println(" inside json validation -- 1");
            JsonNode jsonSchema = JsonLoader.fromResource(schemafilePath);
            System.out.println(" inside json validation -- 2");
            JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
            System.out.println(" inside json validation -- 3");
            JsonSchema schema = factory.getJsonSchema(jsonSchema);
            System.out.println(" inside json validation -- 4");
            ProcessingReport report = schema.validate(data);

这个值出现在poison.h(linux source\include\linux\poison.h)中:

/*
 * Architectures might want to move the poison pointer offset
 * into some well-recognized area such as 0xdead000000000000,
 * that is also not mappable by user-space exploits:
 */

我只是好奇价值的特殊性0xdead000000000000？

我正在使用注释expectedExceptionsMessageRegExp上的propery @Test来测试异常消息,但它没有正确执行.请参阅下面的代码.

单元测试代码:

@Test (dependsOnMethods = "test1", expectedExceptions = IllegalArgumentException.class, expectedExceptionsMessageRegExp = "incorrect argument")
public void testConverter()
{
    try
    {
        currencyConverter  = Converter.convert(val1,val2)
    }
    catch (MYException e)
    {
        e.printStackTrace();
    }
}

申请代码:

if (val1 == null || val1.length() == 0)
{
    throw new IllegalArgumentException("Val1 is incorrect");
}

单元测试代码应检查异常消息,如果消息彼此不匹配,则测试应该失败.

目前这还没有发生.难道我做错了什么？

我已经读过,当ejbPassivate()被称为有状态会话时,豆通常被驱逐,但实体豆和无状态豆被合并,这意味着它们不适用于钝化.

在另一篇文章中,我读到激活和钝化仅适用于有状态会话Bean和实体Bean,这与实体Bean和无状态Bean合并的声明形成对比.

钝化适用于什么豆类？当它们发生时会发生什么？

这是我第一次来这里,如果我犯了一些错误,我很抱歉.

我有一个IE浏览器读取LESS文件的问题.它会引发以下错误:

'SyntaxError:Object不支持test.less中的此属性或方法'

这是一个非常好的特殊div,页面顶部有这些单词.不在调试中,没有什么,它很干净.所有其他浏览器都没有问题.

我整天都在尝试,什么都没有.现在即使我只尝试使用这个LESS文件:这是test.less文件.

body { margin: 0 auto; background-color:red; }

没什么特别的,对吧.但仍然没有.所以我想有一个我不知道的问题.但是什么？

这是我头上的剪辑:

<link rel="stylesheet/less" type="text/css" href="src/showcase/Presentation/Css/test.less" />    
    <script src="src/showcase/Presentation/Script/less.js"></script>
    <script src="src/showcase/Presentation/Script/main.js"></script>

顺便说一句,它在IE 10中有效.

我真的很感激有用的暗示.

通过jboss 5.1.1进行部署时,我遇到了以下错误:

我已经开发了一个普通的Java项目,我想明白之间的差别ClassNotFoundException和NoClassDefFoundException.我发现了一个奇怪的行为,就是我在调用时需要包含整个包结构Class.forName().

请参阅以下代码:

package org.com;

public class MainApp {

    public static void main(String[] args) {
        try {
             Class cls = Class.forName("org.com.MainApp");
             System.out.println("Class = " + cls.getName());
         } catch(ClassNotFoundException ex) {
             System.out.println(ex.toString());
         }
    }

}

如果我使用Class.forName("MainApp")而不是Class.forName("org.com.MainApp")抛出异常.

有人可以解释一下这个的实际原因吗？

我试图通过命令行运行我的Selenium测试.为了实现它,我创建了一个包含多个测试的示例类和一个testng.xml文件.

我在命令行中一个接一个地运行以下命令:

d: 
cd D:\Yes\selenium\sel_mock_aut_tests\Nothing
set pp=D:\Yes\selenium\sel_mock_aut_tests\Nothing
set classpath=%pp%\bin;%pp%\lib\*
java org.testng.TestNG %pp%\ATestNG.xml

这会导致以下错误:

[TestNG] [ERROR] java.lang.NumberFormatException: For input string: "1.0"

我的testng.xml文件看起来像这样(并命名为ATestNG.xml):

<suite name="MyTests" verbose="1.0">
<test name="BatExecution">
    <classes>
        <class name="TestNGOperations.RunUsingBatFile" />
    </classes>
</test>
</suite>

导致错误的原因是什么？如何解决？
