Oracle EBS R12 整合ADF
環境:
ADF version: 11.1.1.6.0
Oracle EBS version: R12.2.3
程式的目的在於取得 EBS 登入時的使用者相關資訊。整個程式架構如下圖:
ADF 的程式面:
Step 01: 在 ViewController 依序建立 Java Class:ConnectionProvider、EBizUtil、EBSWrapperFilter、以及存取使用者資訊的 Java Bean: UserInfo資料的 ConnectionProvider.java程式碼:
package com.oracle.view; import java.sql.Connection; import java.sql.SQLException; import javax.naming.Context; import javax.naming.InitialContext; import javax.naming.NamingException; import javax.sql.DataSource; public class ConnectionProvider { private static DataSource ebsDS = null; static{ try { Context ctx = new InitialContext(); ebsDS = (DataSource) ctx.lookup("jdbc/TEST32"); // your datasource jndi name as defined during configuration if (ctx != null) ctx.close(); } catch (Exception e) { // TODO: Add catch code //ne.printStackTrace(); //ideally you should log it throw new RuntimeException(e); // means jndi setup is not correct or doesn't exist } } private ConnectionProvider() { super(); } public static Connection getConnection() throws SQLException{ if (ebsDS == null) throw new IllegalStateException("AppsDatasource is not properly initialized or available"); return ebsDS.getConnection(); } }
PS: 在 EBS 環境中是以 jdbc 的模式取得資料庫聯機,可以進入 weblogic 的 Services-> Data Sources 檢視,如:EBSDataSource 的 JNDI: jdbc/TEST32 ,並可以得知要佈署到那一個主機上:oacore_cluster1
EBizUtil.java 程式碼:
package com.oracle.view; import java.sql.Connection; import java.sql.SQLException; import java.util.logging.Level; import java.util.logging.Logger; import oracle.apps.fnd.ext.common.EBiz; public class EBizUtil { public EBizUtil() { super(); } private static final Logger logger = Logger.getLogger(EBizUtil.class.getName()); private static EBiz INSTANCE = null; static { Connection connection = null; try { connection = ConnectionProvider.getConnection(); // DO NOT hard code applServerID for a real application // Get applServerID as CONTEXT-PARAM from web.xml or elsewhere INSTANCE = new EBiz(connection, "F1CB87199593E5F4E0431F030A0AD0AB31310251131793525291714692481335"); } catch (SQLException e) { logger.log(Level.SEVERE, "SQLException while creating EBiz instance -->", e); throw new RuntimeException(e); } catch (Exception e) { logger.log(Level.SEVERE, "Exception while creating EBiz instance -->", e); throw new RuntimeException(e); } finally { if (connection != null) { try { connection.close(); } catch (SQLException e) { throw new RuntimeException(e); } } } } public static EBiz getEBizInstance() { return INSTANCE; } }
PS: APPL_SERVER_ID 可以到 EBS APP Server 路徑下的 $INST_TOP/appl/fnd/12.0.0/secure/TEST32.dbc 取得Server ID :
APPL_SERVER_ID=F1CB87199593E5F4E0431F030A0AD0AB31310251131793525291714692481335
EBSWrapperFilter.java程式碼:
package com.oracle.view; import java.io.IOException; import java.sql.SQLException; import java.util.logging.Level; import java.util.logging.Logger; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import oracle.apps.fnd.ext.common.AppsRequestWrapper; import oracle.apps.fnd.ext.common.AppsRequestWrapper.WrapperException; public class EBSWrapperFilter implements Filter { public EBSWrapperFilter() { super(); } private static final Logger logger = Logger.getLogger(EBSWrapperFilter.class.getName()); public void init(FilterConfig filterConfig) { logger.info("Filter initialized "); } public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,ServletException { AppsRequestWrapper wrapper = null; logger.info("-current URI =" + ((HttpServletRequest)request).getRequestURI()); try { wrapper = new AppsRequestWrapper((HttpServletRequest)request, (HttpServletResponse)response, ConnectionProvider.getConnection(), EBizUtil.getEBizInstance()); } catch (WrapperException e2) { logger.log(Level.SEVERE, "WrapperException error encountered ", e2); throw new ServletException(e2); } catch (SQLException e2) { logger.log(Level.SEVERE, "SQLException error encountered ", e2); throw new ServletException(e2); } try { logger.info("Created AppsRequestWrapper object." + " Continuing the filter chain."); chain.doFilter(wrapper, response); logger.info("- the filter chain ends"); } finally { //AppsRequestWrapper caches a connection internally. //AppsRequestWrapper.getConnection()--returns this connection this connection can be used in doGet()/doPost() service layer //whenever our application requires a connection in order to service the current request. //When AppsRequestWrapper instance is in use, this connection should not be closed by other code. //At this point, we are done using AppsRequestWrapper instance so, as good practice, we are going to close (release) this connection now. if (wrapper != null) { try { logger.info("- releasing the connection attached to the" + " current AppsRequestWrapper instance "); wrapper.getConnection().close(); } catch (SQLException e3) { logger.log(Level.WARNING, "SQLException error while closing connection--", e3); throw new ServletException(e3); } } wrapper = null; } } public void destroy() { logger.info("Filter destroyed "); } }
UserInfo.java 程式碼:
package com.oracle.bean;
import java.util.Map;
import javax.faces.context.FacesContext;
import javax.faces.event.PhaseEvent;
import oracle.apps.fnd.ext.common.AppsRequestWrapper;
import oracle.apps.fnd.ext.common.Session;
public class UserInfo {
private String user;
private String userInfo;
public UserInfo() {
super();
}
public void setUser(String user) {
this.user = user;
}
public String getUser() {
return user;
}
public void beforePhase(PhaseEvent phaseEvent) {
// Add event code here...
AppsRequestWrapper wrappedRequest =
(AppsRequestWrapper)FacesContext.getCurrentInstance().getExternalContext().getRequest();
Session session = wrappedRequest.getAppsSession();
setUser(session.getUserName());
Map columns = session.getInfo();
StringBuffer temp = new StringBuffer();
temp.append("<table>");
for (Object key : columns.keySet()) {
temp.append("<tr>");
temp.append("<td>");
temp.append(key);
temp.append("</td>");
temp.append("<td>");
temp.append(columns.get(key));
temp.append("</td>");
temp.append("</tr>");
}
temp.append("</table>");
setUserInfo(temp.toString());
}
public void setUserInfo(String userInfo) {
this.userInfo = userInfo;
}
public String getUserInfo() {
return userInfo;
}
}
Step 02:在 adfc-config.xml 建立 view: userInfo.jspx 及 設定 Managed Beans
userInfo.jspx
版面:PageGroupLayout :layout = vertical
OutPutText:value="Hello #{pageFlowScope.userInfoBean.user}!!"
inlineStyle="font-size:medium; color:Red;"
Separator
OutPutText:value="#User Info:<br>#{pageFlowScope.userInfoBean.userInfo}"
escape="false"
inlineStyle="font-size:medium;"
Managed Beans:userInfoBean :
Step 03: 設定 userInfo.jspx 的 beforePhase
這是在 UserInfo.java 的一段程式
public void beforePhase(PhaseEvent phaseEvent) {
// Add event code here...
AppsRequestWrapper wrappedRequest =
(AppsRequestWrapper)FacesContext.getCurrentInstance().getExternalContext().getRequest();
Session session = wrappedRequest.getAppsSession();
setUser(session.getUserName());
Map columns = session.getInfo();
StringBuffer temp = new StringBuffer();
temp.append("<table>");
for (Object key : columns.keySet()) {
temp.append("<tr>");
temp.append("<td>");
temp.append(key);
temp.append("</td>");
temp.append("<td>");
temp.append(columns.get(key));
temp.append("</td>");
temp.append("</tr>");
}
temp.append("</table>");
setUserInfo(temp.toString());
}
Step 04 : web.xml 中設定 Filters
Oracle EBS 上的設定 :
Step 01: 設定 Function : Menu: Responsibiliey:
Function: WEI_ADFLAB_USERINFO
Function |
WEI_ADFLAB_USERINFO |
Properties-Type |
External ADF Application |
WebHTML-HTML Call |
GWY.jsp?targetPage=faces/userInfo |
Menu:WEI_LAB_MENU
Responsibility: WEI Labs
Step 02: Responsibility: Functional Administrator 上的設定
a.Core Services → Profiles → Code: FND_EXTERNAL_ADF_URL → Go
b.然後點選External ADF Application URL 後按 Define Profile Values
a. 點選Define Profile Values → Responsibility
b. 選擇 Responsibility & Value
c. Value: 客製程式在 weblogic 的路徑,如: http://lnxap104:7214/LAB_EBS-ViewController-context-root/ ,最後要加 /
d. 按 Update
一個Responsibility只能繫結一個程式的root,所以如果有多個功能,可能要放在同一包應用程式裡面。也有其它使用者在問此問題,但現在並沒有進一步的解法。例如: Oracle論壇,其他使用者提問的 >> 問題
Step 03: 清除 Caching Framework & Testing
