taglib

问题 I have a custom JSP tag which is using a parameter which is an enum. This approach is a consequence of using other classes which need this enumeration. The point is I have no clue how to assign an enum value in the EL: <mytaglib:mytag enumParam="${now what do I type here?}" /> The only workaround which I found so far was to make the enumParam an Integer and convert it to desired values: <mytaglib:mytag enumParam="3" /> I believe there must be a better way to do it. Please help. 回答1: EL allows

问题 Is it possible to integrate Spring beans and JSP tags somehow in Spring. That is use a Spring bean as a JSP Tag? And if so is this a good/terrible idea? So something like this would be possible: @Component public class SomeBean extends SimpleTagSupport { @Autowired SomeBean someBean; @Override public void doTag() throws JspException, IOException { getJspContext().getOut().write(someBean.doSomething()); } } What would I do in the tags.tld to get it to use the Spring bean instead of creating a

问题 Total 'testing newbie' wanting to test the addJsFile method of my custom TagLib. What am I missing? TagLib: import com.company.group.application.helper.Util ... class MyTagLib { static namespace = 'mytag' def util ... def addJsFile = { if (util.isSecureRequest(request)) { out << '<script src="https://domain.com/jsfile.js"></script>' } else { out << '<script src="http://domain.com/jsfile.js"></script>' } } } Test (as far as I could get): import org.springframework.http.HttpRequest import com

问题 I'm trying to add metadata keywords to image files using Taglib-Sharp. My problem is that the following code: image.ImageTag.Keywords = (string[])newTags.ToArray(typeof(string)); image.Save(); does nothing if there are no keywords in the file to begin with. If I open the file properties in Explorer and add tags manually first, it works just fine and adds the tags to the file. I've tried setting a breakpoint at the top of this method and I can see that image.ImageTag.Keywords has a length of

问题 I am quite new to the C++ 'area' so I hope this will not be just another silly 'C++ strings' question. Here is my problem. I want to integrate TagLib (1.5, 1.6 as soon as I manage to build it for Windows) into an existing Windows MFC VS2005 project. I need it to read audio files metadata (not write). The problem is that the program stores the input file names using CString(), and it has the Unicode option turned on (so the default chars are "wchar_t"). The reason for this (I think, the

问题 Using taglib-sharp and OleDb, I'm attempting to index a folder of music files and store all the metadata from said files in an Access Database (I'll probably switch to SQL Compact or something later but the book I have uses Access). The below code should retrieve and store the metadata of the first 1000 files in a given folder and subfolders OleDbCommand cmd = con.CreateCommand(); DirSearch(@"C:\Users\Stephen\Music"); TagLib.File tagFil; for (int i = 0; i < 1000; i++) { tagFil = TagLib.File

问题 I've got a two classes (pupil, class) in a Roo-project and their scaffolded views. pupil and class have a 1:1 relationship In the list.jspx of pupil I'd like to display a column for a property of class. I don't know the correct attributes to give to the table:column-tag. This following example gives the error: SpelEvaluationException: EL1027Epos 4): Indexing into type 'com.pupil' is not supported <table:table data="${pupil}" duplicate="true" id="l_com_pupil" path="/admin/pupil" z="user

问题 I am trying to set the image from a stream. However when I set the source from the background thread and use a dispatcher it freezes the app completely. The stream is not null, I have verified that. I am using the taglib api to get the stream of the album picture of an mp3 file. I've tried everything. async void Background(object sender, MediaPlayerDataReceivedEventArgs e) { IRandomAccessStream AlbumArtStream = await Media.GetAlbumArt(MediaFile.Name, await MediaFile.OpenStreamForReadAsync());

问题 A list of books is displayed on the page. When a user clicks a book, its detail page is opened. Now the problem is that I need to encode each book's id with the detail page url. The link to detail page is /loadDetailForm.do. If a book has id=23, the link should appear as /loadDetailForm.do?id=23. I am pasting code here: <logic:notEmpty name="BrowseForm" property="books"> <logic:iterate id="book" property="books" name="BrowseForm" type="com.nms.bks.app1.domain.Book"> <p><html:link action="
