      Hey, I've got an idea! After all, EJB already exists and has a shorter name. Jesus, in my very first reply in this thread , I wrote:. It seems more or less related to WELD , but I'm not sure that my patch will help you if you don't have a local interface. Home Content Places Search Cancel. Error: You don't have JavaScript enabled.

NotSerializableException: services.The situation is similar as 1a. When T2 commits, it attempts to acquire an exclusive lock and blocks. The system is blocked again. Conclusion: it's fine with optimistic locking if no premature flushes happen, which you can not stricly control.What is the difference between Inject and EJB. Asked 4 Months ago Answers: 5 Viewed 46 times. Hm, let's list all cases. The read by T1 does not acquire a lock. The read by T1 acquire a shared lock. The situation is similar as 1a 2b If T1 did not flush prematurly, T1 holds a shared lock. Only authorized users can answer the question.

If not, is it possible to create an EJB via a Producer method that performs some configuration upon creation? In our case it works only with Inject but not with EJB. Posted by  Thanks for this clear explanation! This was exactly what I was wondering However if you're building portlets for liferay you cannot use the CDI adding the beans.Just create 2 Java classes and Inject them into each other's public fields. If that works then my answer is wrong. If that does not work, then my answer is correct so far.Next change the Inject to EJB and possibly annotate the classes themselves? I forget. Then the cyclic mutual injection should work fine. Hope this makes sense. I created two pojo's and injected the pojo's into each other.Works without problems in my config WildFly 8. Thanks MartijnBurger, I'll confirm that, and in the meanwhile add a note of caution to my answer. No exactly sure what you wanted to achieve, but this probably does exactly what you wanted and without a circular dependency. Also asynchronous CDI events could be a cleaner way to go depending on the requirements. Basically, Inject is always better, since: it is more typesafe, it supports Alternatives, and it is aware of the scope of the injected object.John Manko John Manko 1, 20 20 silver badges 45 45 bronze badges.

Sharelines from this story. What's the difference between natural gas, liquid natural gas, shale gas, shale oil and methane? You have been signed up successfully.Both are gases at standard temperature and pressure STP. Butane has  LPG is produced during natural gas processing and crude oil refining. Once refined, LPG is stored as a liquid under pressure in gas bottles or tanks. Times have changed and natural gas is no longer the presumed low cost option. LPG supply is often less expensive than natural gas.Natural gas is methane vs LPG which is propane, butane, isobutane or a mixture of the three. Mains gas natural gas is delivered through pipelines whilst CNG comes in natural gas bottles. The calorific value of natural gas and CNG are the same at  The difference between CNG and propane is that while CNG and propane both come in gas bottles, propane gas bottles are much lighter vs natural gas bottles.They are also different gases, as CNG is methane. Propane is stored under pressure as a liquid vs CNG which is stored as a compressed gas in natural gas bottles.The appliances that run on the piped gas connection cannot be used on the LPG gas connection and vice versa. The chemical formula for both butane and isobutane are the same — C 4 H  In its refined form, natural gas is an odourless, colourless gas of predominantly methane. Methane is the simplest hydrocarbon molecule with one carbon atom and four hydrogen atoms constituting a highly flammable gas with the chemical formula CH 4. The natural gas formula is CH 4 , is actually the formula for methane.Natural gas methane is a flammable hydrocarbon fuel gas. To be accurate, this natural gas chemical formula is actually the chemical formula for methane, which is the primary constituent of refined natural gas piped to your home.Raw natural gas, straight out of the ground, also contains natural gas liquids and various impurities. The chemical formula — CH 4 — which means that CNG methane contains one carbon atom and four hydrogen atoms. This single carbon atom means that CNG methane is the lowest carbon hydrocarbon fuel, even lower than propane, which only has 3 carbon atoms and much lower than diesel fuel, with an average of 12 carbon atoms per molecule.The chemical composition of CNG is the same as natural gas. To be accurate, this CNG formula is actually the chemical formula for methane, which is the primary constituent in the chemical composition of CNG. There is little difference between refined natural gas and methane. However, there is a big difference between methane and raw natural gas straight from the well, which contains NGLs and impurities, in addition to methane.Is LPG cheaper than natural gas? Natural gas is generally cheaper than LPG for the gas itself. LPG has a higher energy content and the relative positions of LPG vs natural gas price has changed over time, with LPG now cheaper than natural gas in many cases. Many customers now find that it is cheaper to go with LPG vs natural gas. LPG is now better because it frequently costs less than natural gas. For some low volume users, the total cost of the LPG is cheaper and may be less than half of the cost of the natural gas.When considering LPG vs natural gas cost, times have changed and natural gas is no longer the presumed low cost option. New higher natural gas tariffs and the average cost of LPG vs natural gas makes LPG cheaper than natural gas in many situations. The gas market in different countries may vary. You can see how LPG is better than natural gas when you buy a cooktop. Cooktops usually come with two sets of gas jets. The ones for LPG have a much smaller hole and use less gas. LPG gas has some distinct advantages, including portability and higher energy content.It may also be cheaper than natural gas in many situations. Natural gas has a safety advantage vs LPG. As natural gas is lighter than air, in the event of a leak, natural gas will dissipate more quickly.As LPG propane is heavier than air, it may collect in basements or near the floor of a home. Natural gas has some other advantages, too. So, as to if LPG is better than natural gas, it really comes down to a matter of opinion.Both gases have their advantages. The calorific value of natural gas heating value of natural gas is  The calorific value of LPG gas propane is  So, LPG has a higher energy content than the calorific value of natural gas heating value of natural gas. With this higher calorific value, less LPG is required to produce the same amount of heat.The heating value of methane is  Propane has a higher heating value — energy content — than the heating value of methane, with  It would be difficult, if not impossible, to tell the difference between cooking with LPG-propane vs natural gas. The difference between cooking with propane vs natural gas is an even draw. Propane vs natural gas methane vs propane cooking flame temperatures are almost identical, they both respond instantly to cooking temperature control changes and they both look the same.The cooking user would be unaware of the differences in gas to air ratio and propane vs natural gas supply pressure. Comparing the cooking energy content of propane vs natural gas, natural gas is lower but it is typically less expensive so it tends to cancel out.It really comes down to the prices and tariffs of the two to determine which has a lower effective cost, after daily supply charges network access fee , other charges and the actual cost of the gas. The autoignition temperature is the lowest temperature at which a substance spontaneously ignites in air, with no other ignition source.So, based on their respective autoignition temperatures, propane is more flammable than methane because it spontaneously ignites at a lower temperature. CNG releases less greenhouse gas, while LPG releases carbon dioxide, but is still cleaner than gasoline.Knowing about the different types of alternative fuels can benefit you greatly in your diesel career.
