问题 In our application we need send some data to foreign customer server web service JAX-WS. I generated required client files from WSDL with using wsimport . Then I tried connect to server side web service. But with Java 1.7.0_67 64bit connection wasn't successfull.

问题 I'm trying to use sqoop to import a MySQL table into HDFS. I'm using JDK 1.7.0_45 and CDH4.4. I'm actually using cloudera's pre-built VM, except I changed the JDK to 1.7 because I wanted to use the pydev plugin for eclipse. My sqoop version is 1.4.3-cdh4.4.0.

问题 Goal: Launch SWT Web Start application on Mac using Java 7 In order to run an SWT RCP application on Mac OS X, it is well documented that it is necessary to include -XstartOnFirstThread as part of the Java Virtual Machine arguments. Unfortunately, Java Web Start seems to be deleting this argument. Looking at Java Web Start’s detailed tracing logs: temp: returning LaunchDesc from XMLFormat.parse(): <jnlp spec="1.0+" codebase=“..." href=“..."> <information> ... <resources> <java java-vm-args="

问题 I modified some code in my current web project to add Spring transaction management. Everything works just fine when I deploy it in Eclipse or even when I call a "Maven clean" and a "Maven install" in my workspace. However when my continuous integration server (jenkins) tries to redeploy it on my distant server I get a java.lang.VerifyError and it fails: maven-glassfish-plugin:2.1:deploy (default-cli) @ myApp --- [INFO] asadmin --host localhost --port 4848 --user admin --passwordfile C:

问题 I see a few question with this title already. I have checked it, if it has a solution for me, but not.
