Jasper report errors- Invalid character found in method name. HTTP method names must be tokens

[Frank Messie]

Invalid character found in method name [0x160x030x010x07O0x010x000x07K0x030x03P0xff0x930xeb0x160x03b0x020x110x0d[w0x820xbd0xc80xfa0xb8{0x9a0x040x910xbe0xf3d0x0eT0x0bz0xd8i0x160xd7 ]. HTTP method names must be tokens

We are running the example as described in lesson 2.
It is now compiling and running without errors. But as soon as we create a report we get Null as a result in the fields and in OpenXava console we get the long message.
What is wrong ?

Hi Frank,

Remember the forum rules:
https://sourceforge.net/p/openxava/discussion/419690/thread/84073f3433/
That is because, basically we have not magic powers, so we need to examine the code and the stacktrace to figure out what is happening.

Put here the complete code of your print action.
Attach your JRXML.
And the most important, put here the stack trace produced when you click on Print and it fails.
