Weblogic 10 ANTLR issue

Due to the issue of ANTLR that weblogic 10 uses internally, we need to add a file WEB-INF/weblogic.xml with the following contents to solve the conflict:


<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app
xmlns="http://www.bea.com/ns/weblogic/90"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90
                    http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">

   <container-descriptor>
      <prefer-web-inf-classes>true</prefer-web-inf-classes>
   </container-descriptor>
</weblogic-web-app>


This file make Weblogic use classes and libraries in the web application before other libraries in the classpath.

public ActionForward doViewAttachFile(ActionMapping aMapping, ActionForm aForm,
HttpServletRequest aRequest, HttpServletResponse aResponse) throws Exception {
Efp136Form efp136Form = (Efp136Form) aForm;
Efp136m efp136m = (Efp136m) efp136Form.getEntity();

String fileName = URLEncoder.encode(efp136m.getAttachFileName(), "UTF-8");
aResponse.setHeader("Content-disposition", "attachment; filename=" + fileName);
aResponse.setContentType(efp136m.getAttachFileType());
aResponse.setContentLength(efp136m.getAttachFileSize().intValue());

ServletOutputStream servletOutputStream = aResponse.getOutputStream();
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(servletOutputStream);
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(efp136m.getAttachFileData());
BufferedInputStream bufferedInputStream = new BufferedInputStream(byteArrayInputStream);
byte[] bytes = new byte[2048];
while (bufferedInputStream.read(bytes) != -1) {
bufferedOutputStream.write(bytes);
}

servletOutputStream.flush();
byteArrayInputStream.close();
servletOutputStream.close();
return aMapping.findForward(VIEW_ATTACH_FILE_SUCCESS);
}

根據hibernate configuration file建立table schema

程式範例如下：

package mytest;

import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;

public class SchemaExportTester {

public static void main(String[] args) {
new SchemaExportTester().createSchema();
}

private void createSchema() {
Configuration cfg = new Configuration().configure();
SchemaExport schemaExport = new SchemaExport(cfg);
schemaExport.setOutputFile("schema.sql");
schemaExport.create(true, true);
System.out.print("ok");
}
}


其中
schemaExport.create(true, true);
第一個參數是表示是否要產生schema.sql，第二個參數是表示是否要在database立建立table。
