使用cxf从wsdl生成java代码会产生代码太大的错误

Question

I have generated the code form wsdl to java using cxf 2.7.3 but when building the assembly I get "code too large" error. Indicating that one of the methods have exceeded java 64kb limit. I know exactly which class and to me this seems like bug in cxf. Actully Axis2 does the same so I was wondering if anyone knows how to solve this.

The code I'm playing around with is provided here in path eco-api-ex / examples / java /

How can I force the code generation to split up large generated method? or should I use some external tool for this?

Answer 1

Don't run wsdl2java with the -client flag. The _Client.java class is just a sample class to show how to use the generated service class and proxies and such. It's not normally needed for anything. That SHOULD be the only class generated with a large method like that.

Answer 2

You've got a 3MB WSDL document there. (No wonder my browser was a bit unhappy when I tried to view a general XML document of that size.) It's got around 3000 elements defined in it; also 3k messages and 4.5k operations. I don't know exactly what you're hitting the limit in (there's a few places where registries of all entities of a particular type are constructed) but it doesn't matter too much. It's just far too large for most code to normally handle. (The limit you're hitting appears to be the one on the total size of bytecode for a method; hitting that is usually an indication of something somewhere else going badly awry: in this case, it's the bunker-busting WSDL document.)

Constructing a cut-down version that has a much smaller set of elements, messages and operations would be an excellent idea. Putting that cut-down version in your repository where Maven can find it (eg, in src/main/wsdl ) would also make a lot of sense, as it would stop you from downloading that 3MB document again each time you build.
