Windchill Java 代码：根据流程模板查找具体流程节点

以下是一个简单的示例代码，可根据流程模板 ID 查找具体流程节点：

import wt.fc.PersistenceHelper;
import wt.fc.QueryResult;
import wt.method.RemoteMethodServer;
import wt.org.WTPrincipal;
import wt.org.WTPrincipalReference;
import wt.pom.Transaction;
import wt.query.QuerySpec;
import wt.query.SearchCondition;
import wt.workflow.engine.ProcessData;
import wt.workflow.engine.ProcessDefinition;
import wt.workflow.engine.ProcessTemplate;
import wt.workflow.engine.WfProcess;

public class FindProcessNode {

    public static void main(String[] args) throws Exception {
        RemoteMethodServer rms = RemoteMethodServer.getDefault();
        rms.setUserName('admin');
        rms.setPassword('admin');

        String processTemplateId = 'myProcessTemplateId';

        try (Transaction tx = new Transaction()) {
            ProcessTemplate processTemplate = ProcessTemplate.newProcessTemplate();
            processTemplate.setTemplateID(processTemplateId);
            QuerySpec qs = new QuerySpec(ProcessDefinition.class);
            qs.appendWhere(new SearchCondition(ProcessDefinition.class, ProcessDefinition.TEMPLATE_REFERENCE + '.' + ProcessTemplate.ID_NAME, SearchCondition.EQUAL, processTemplate.getPersistInfo()));
            QueryResult qr = PersistenceHelper.manager.find(qs);
            while (qr.hasMoreElements()) {
                ProcessDefinition processDefinition = (ProcessDefinition) qr.nextElement();
                WfProcess wfProcess = initializeProcess(processDefinition);
                ProcessData processData = wfProcess.getContext();
                // 根据 processData 中的信息查找具体流程节点
                // ...
            }
            tx.commit();
        }
    }

    private static WfProcess initializeProcess(ProcessDefinition processDefinition) throws Exception {
        WTPrincipal principal = WTPrincipalReference.newWTPrincipalReference('admin').resolve();
        WfProcess wfProcess = null;
        try {
            wfProcess = WfProcess.newWfProcess(principal);
            wfProcess.setDefinition(processDefinition);
            wfProcess.setName(processDefinition.getName());
            wfProcess.getContext().setProcess(wfProcess);
            wfProcess.getContext().setContainerReference(wfProcess);
            wfProcess.setNumber(WfProcess.getNextNumber());
            wfProcess.getContext().setNumber(wfProcess.getNumber());
            wfProcess = (WfProcess) PersistenceHelper.manager.store(wfProcess);
            return wfProcess;
        } catch (Exception e) {
            if (wfProcess != null) {
                PersistenceHelper.manager.delete(wfProcess);
            }
            throw e;
        }
    }

}

在上面的代码中，首先需要设置用户名和密码以进行远程调用。然后，通过流程模板 ID 查找对应的流程定义，然后初始化一个流程实例，从中获得流程上下文 ProcessData，最后根据 ProcessData 中的信息查找具体流程节点。

需要注意的是，该示例代码仅适用于 Windchill 11 和 12，Windchill 10 中的 API 可能略有不同。
