Question

给为大侠给我看看这个代码: 
System.out.println("Inside Test_1"); 
m_test.begin("1.1", "Create new Instance object"); 
MInstance level1 = m_app.getClassRegistry().getDataFactory().newInstance("/tibco/public/class/ae/level1"); 
level1.set("name", "level1_name"); 
level1.set("qty", new Integer(10)); 
m_test.pass(); m_test.begin("1.2", "Create new Sequence object"); 
MSequence seqInt4 = m_app.getClassRegistry().getDataFactory().newSequence("/tibco/public/sequence/ae/seq[i4]"); 
seqInt4.append(new Integer(10)); 
seqInt4.append(new Integer(11)); 
seqInt4.append(new Integer(12)); 
level1.set("seqId", seqInt4); 
m_test.pass(); String name = (String) level1.get("name"); 
int qty = ((Integer) level1.get("qty")).intValue(); 
m_test.begin("1.3.1", "Get name from instance"); 
if (name.equals("level1_name")) { 
System.out.println("pass: name = " + name); 
m_test.pass(); 
} else { 
System.out.println("fail: name = " + name); 
m_test.fail(); 
} 
m_test.begin("1.3.2", "Get qty from instance"); 
if (qty == 10) { 
System.out.println("pass: qty = " + qty); 
m_test.pass(); 
} else { 
System.out.println("fail: qty = " + qty); 
m_test.fail(); 
} 
m_test.begin("1.4", "Create sequence[level1] and impilcit test for newContainedData()");

MInstance seqLevel1_0 = (MInstance) seqLevel1.newContainedData(); 
seqLevel1_0.set("name", "seqLevel1_0");

try {

else

}

Answer 1

MInstance 接口能找到吗?
编译器和真正的运行期是有区别的
你把一个包加入到Classpath中,是不会在编译期报错,但是如果你在Tomcat的lib下没有这个包,同样是不成的.

Answer 2

Note: /adapters/adasdkqa/sdk_suit/qa_test/java/common/MComparator.java uses or overrides a deprecated API. 此API已经过时,改用它的新API.

Answer 3

你用的MInstance 已经被JDK新版废弃而保留名称的类,
你得去找官网或文档里面去找覆盖了MInstance 的新类.

Answer 4

造成原因是你的旧系统用了新版的JDK

又报这个错误

Answer 6

我把我的jre下的rt.jar  换成jdk1.4的rt.jar  报这个错误Error occurred during initialization of VM
java.lang.NoSuchMethodError: java.lang.System.nanoTime()J
sh: 6452 Abort(coredump)上边这个错误没有了
