我试图在Windows中使用参数启动JBoss但是出现了一些错误.如果我删除参数比JBoss启动iwht没有错误.有人可以看看.

环境变量:

JAVA_HOME=C:\Java\jdk1.6.0_45
JBOSS_HOME=C:\bin\jboss-eap-6.1
Path=C:\Java\jdk1.6.0_45\bin;C:\WINDOWS\system32;

用以下参数启动jboss:

set "JAVA_OPTS=%JAVA_OPTS% 
    -Djava.rmi.server.hostname=myhost
    -Dcom.sun.management.jmxremote.port=myport
    -Dcom.sun.management.jmxremote.ssl=false
    -Dcom.sun.management.jmxremote.authenticate=true
   -Dcom.sun.management.jmxremote.password.file=C:\Java\jdk\jre\lib\management\jmx.password
   -Dcom.sun.management.jmxremote.access.file=C:\Java\jdk\jre\lib\management\jmx.access
"

错误:

WARNING: failed to load the specified log manager class org.jboss.logmanager.LogManager
Error: Operation <"parallel-extension-add"> failed - address:<[]>
                   java.lang.RuntimeException: failed initializing module org.jboss.as.logging

================================================== ========================

所以要解决上面的错误.我在下面添加了logmanager参数.

使用参数启动jboss:

set "JAVA_OPTS=%JAVA_OPTS%
-Djava.util.logging.manager=org.jboss.logmanager.LogManager
-Djava.rmi.server.hostname=myhost
-Dcom.sun.management.jmxremote.port=myport
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=true
-Dcom.sun.management.jmxremote.password.file=C:\Java\jdk\jre\lib\management\jmx.password
-Dcom.sun.management.jmxremote.access.file=C:\Java\jdk\jre\lib\management\jmx.access
?"

错误:

Could not load Logmanager "org.jboss.logmanager.LogManager"
java.lang.ClassNotFoundException: org.jboss.logmanager.logManager

================================================== ========================

所以修复上面的错误.我添加了-xbootclasspath参数.

使用参数启动jboss:

set "JAVA_OPTS=%JAVA_OPTS%
-Djava.util.logging.manager=org.jboss.logmanager.LogManager"
-Xbootclasspath:C:\bin\jboss-eap-6.1\modules\system\layers\base\org\jboss\logmanager\main\jboss-logmanager-1.4.0.Final-redhat-1.jar

-Djava.rmi.server.hostname=myhost
-Dcom.sun.management.jmxremote.port=myport
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=true
-Dcom.sun.management.jmxremote.password.file=C:\Java\jdk\jre\lib\management\jmx.password
-Dcom.sun.management.jmxremote.access.file=C:\Java\jdk\jre\lib\management\jmx.access
?"

错误:

我是java来创建一个strut项目但是出现错误。我相信这个错误是因为缺少 jar 文件，我不知道要下载哪个版本。

这是我的 lib 文件夹中的 jar 文件：

commons-digester-2.1.jar

commons-logging-1.2.jar

commons-beanutils-1.9.2.jar

commons-collections4-4.0.jar

commons-validator-1.4.1.jar

jasperreports-javaflow-6.1.0.jar

jasperreports-6.1.0.jar

我正在使用 java、libgdx 和 box2d

在主类中我创建了一个播放器。我想在玩家类中将 shape.setAsBox 更改为 100 。换句话说，我想在创建 shape.setAsBox 后对其进行更改。我相信做到这一点的唯一方法是删除夹具并重新创建一个大小为 100 的新夹具。我怎样才能做到这一点。

public class main{
  ...
  public main(){
    //create player
    BodyDef bdef = new BodyDef();
    Body body;
    FixtureDef fdef = new FixtureDef();
    PolygonShape shape = new PolygonShape();

    /***Body - Player ***/
    bdef.type = BodyType.DynamicBody;
    bdef.position.set(50 / PPM, 50 / PPM);
    bdef.linearVelocity.set(1.5f, 0);
    body = world.createBody(bdef);

    /*** 1st fixture ***/
    shape.setAsBox(50/ PPM, 50 / PPM);
    fdef.shape = shape;
    fdef.filter.categoryBits = Constants.BIT_PLAYER;
    fdef.filter.maskBits = Constants.BIT_GROUND;
    body.createFixture(fdef).setUserData("player");

    player = new Player(body);
  } …

我想做什么:

我想用MS 8连接我的MS Access数据库.所以我使用"UcanAccess"驱动程序连接到我的数据库.

我在用什么:

Eclipse,Java 8和MS Access数据库

我的MS Access数据库路径:

C:/Users/dave/My_WorkSpace/Eclipse_Workspaces/workspace-jsp/Database11.accdb"

我的项目中有以下Jar文件:

• MySQL的连接器的Java-5.1.35-bin.jar

• ucanaccess-2.095.jar

• jackcess-2.1.2.jar

• 的hsqldb.jar

• 公地lang3-3.4.jar

• 共享记录-1.2.jar
