我想从worklight适配器调用java类 [英] i want to call a java class from the worklight adapter
问题描述
我已在此网址中跟踪此文档模块5.5 http ：//www.ibm.com/developerworks/mobile/worklight/getting-started.html#authentication 或 ftp://public.dhe.ibm.com/software/mobile-solutions/worklight/docs/v505/Module_05_5_-_Using_Java_in_Adapters.pdf
i have followed this document module 5.5 in this url "http://www.ibm.com/developerworks/mobile/worklight/getting-started.html#authentication" or ftp://public.dhe.ibm.com/software/mobile-solutions/worklight/docs/v505/Module_05_5_-_Using_Java_in_Adapters.pdf
和我的代码结构相同
server/java folder name
com.worklight.custonmode package name
loginfunction.java java file inside com.worklight.custonmode package
login java method in class loginfunction
我从工作灯适配器调用了
and i have called from the worklight adapter as
function loginmodules(username, passwd) {
return {
result : com.worklight.custonmode.loginfunction.login()
};
}
当我打电话时收到这样的错误
when i am calling am getting the error like this as
response [/apps/services/api/Light/common/query] success: /*-secure- {"responseID":"2","errors":["Ecma Error: TypeError: Cannot call property login in object [JavaPackage com.worklight.custonmode.loginfunction]. It is not a function, it is \"object\".

我在loginfunction.java中的登录功能
my login function in loginfunction.java

推荐答案
我只想出了这个。有趣的是，每个人都对这个问题保持沉默两个月。对我而言，它根本不是很明显，因为它适用于某些项目，而其他项目则不然。机器也是如此。它可以在一个地方工作，但不能在另一个地方工作（如果你不知道发生了什么）。
I just figured this out. It's funny how everyone went silent on this issue for two months. For me it wasn't obvious at all because it works in some projects and simply doesn't in others. The same is true for machines. It'll work one place, but not another (if you're not aware of what's going on).
检查.project文件并确保它是正确的buildCommand标签。
Check your .project file and make sure it has the right buildCommand tags in it.
<buildCommand>
<name>org.eclipse.jdt.core.javabuilder</name>
<arguments>
</arguments>
</buildCommand>
